Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin
- UUSC - COPAE-
INTRODUCCIÓN
La mina Marlin es operada y pertenece a Montana Exploradora de Guatemala,
S.A., subsidiaria absoluta de la empresa transnacional Goldcorp, Inc. La mina
está ubicada en el norte del departamento de San Marcos en los municipios de
San Miguel Ixtahuacán y Sipacapa.
Montana ha proporcionado una fianza de garantía de $1 millón (Montana
Exploradora de Guatemala, S.A., 2010, p. 50) que el gobierno puede utilizar para
recuperar la mina en caso de que la empresa no cumpla sus obligaciones. Esta
cantidad es insignificante en comparación con las fianzas de recuperación que
se exigen paralas operaciones mineras en otras partes. Por ejemplo, las fianzas
de recuperación de cuatro minas en Colorado, EE.UU. son:
·
·
·
·
Cresson: oro, tajo abierto, tanque de lixiviación, planta de procesamiento$99 millones;
Climax: molibdeno, mina subterránea y tajo abierto, planta de
procesamiento-$52 millones;
Henderson: molibdeno, mina subterránea, planta de procesamiento-$41
millones; y
San Luis: oro y plata, tajo abierto, planta de procesamiento-$7.4 millones
(Colorado DivisionofReclamation, Mining and Safety, 2010).
Aunque los requisitos de recuperación para estas cuatro minas no son
totalmente comparables con la mina Marlin, muchas de las tareas de
recuperación son similares y los costos totales de recuperación anteriores
indican la magnitud de las fianzas de garantías para recuperación en minas
modernas. También se ha observado que la fianza de garantía para la mina
Marlin es baja (On Common Ground, 2010, p. 16; E-Tech, 2010, p.8).
La baja fianza de garantía para la mina Marlin expone al gobierno, a residentes
locales y al medio ambiente a riesgos significativos por cualquier incumplimiento
de Montana en recuperar la mina correctamente. Estos riesgos incluyen la
continua contaminación de efluentes con metales tóxicos y ácidos; erosión y
sedimentación; y tierras alteradas que no pueden devolverse a su uso anterior.
Estos riesgos se discuten en mayor profundidad en la siguiente sección.
El total calculado aproximado de esta investigación para una fianza de garantía
apropiada para la mina Marlin es Q389 millones o $49 millones, obviamente un
aumento significativo sobre la fianza actual. Esta cantidad provee para la
operación indefinida de la planta de tratamiento de agua actual; cubrir la roca
estéril de la mina y colas de procesamiento de la mena; nivelar las tierras
alteradas a formaciones terrestres naturales; control de erosión; la extracción de
edificios, equipo y desechos; y revegetación.
Si se demuestra que el
retratamiento de agua no es necesario, se puede devolver aproximadamente
una cuarta parte de la fianza a Montana. De modo parecido, porciones de la
1
Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin
- UUSC - COPAE-
fianza aplicables podrían devolverse, si se puede certificar que Montana está
realizando adecuadamente la recuperación concurrente.
El costo de recuperación fue estimado con software de computadoras que es
extensivamente aceptado y usado dentro de los EE.UU. Los reguladores del
estado de Nevada y la industria minera de ese estado prepararon el software y
costos unitarios juntos. Donde fue disponible, datos de entrada para el software
fueron tomados de documentos públicos de Montana y Goldcorp.
Desafortunadamente, estos documentos carecen de información de
recuperación y algunos datos de entrada tuvieron que ser asumidos en base a la
experiencia y cálculo de los autores. Si se obtienen datos adicionales, se
pueden actualizar las entradas para el software. Por ejemplo, un calculador
profesional de costos guatemalteco podría ajustar las tasas de costos de
unidades usados a las tasas locales. La tercera sección de este informe
describe la estimación total de costos de recuperación y el software usado. El
anexo adjunto contiene las hojas de cálculo.
La segunda sección de este informe da un resumen de los riesgos de
recuperación presentados por Marlin. Para los lectores no familiarizados con los
planes de recuperación, la cuarta sección describe el contenido y nivel de detalle
requerido generalmente.

RIESGOS AMBIENTALES DE LA MINERÍA
Aunque la mayoría de empresas mineras son medianamente responsables en
cuanto al medio ambiente, siguen ocurriendo desastres monumentales. Algunos
ejemplos de desastres relacionados a la minería de oro incluyen los siguientes:
·
·
·
·
Baia Mare, Rumania: En enero del 2000, una brecha de un dique de colas
descargó unos 100,000 metros cúbicos de colas conteniendo mucho
cianuro al sistema de ríos. Este derrame descargó aproximadamente 50
a 100 toneladas de cianuro, tanto como metales tóxicos, en particular el
cobre, a los Ríos Somes y Tisza y finalmente al Río Danubio antes de
llegar al Mar Negro.
Omai, Guyana: La brecha de un dique de colas en agosto de 1995
descargó 3.5 millones de metros cúbicos de efluente tóxico que contenía
cianuro y metales tóxicos a los ríos Omai y Essequibo.
GiltEdge Mine, EE.UU.: Después que la mina cerró en 1992, efluentes de
metales tóxicos y ácidos se filtraron desde las escombreras de roca estéril
de mina y agua contaminada llenando tres tajos abiertos. El dueño se
volvió insolvente en 1999 antes de terminar la limpieza.
Subsecuentemente la Agencia de Protección del Medio Ambiente (EPA)
de los EE.UU. tuvo que financiar la limpieza.
Yanacocha, Perú: La mina ha descargado efluentes de metales tóxicos y
ácidos a ríos locales, y estos ríos tienen una corriente disminuida como
resultado del consumo de agua por la mina. Los efluentes tóxicos y el
bajo nivel de agua impactan el agua potable y la agricultura. También ha
ocurrido un derrame de mercurio en tránsito hacia la mina.
Ésta es una lista corta de muchos desastres recientes del medio ambiente como
resultado de la minería de oro. La Agencia de Protección del Medio Ambiente
(EPA) de los EE.UU. (1997, p. 1) resumió de 1990 a 1997, en solo ocho estados,
62 casos de descargas tóxicas y daños al medio ambiente de la minería y el
procesamiento de la mena. Cuarenta y nueve de estos casos involucraron
colas, pozas, la roca estéril de mina, la solución de procesamiento (por ejemplo,
cianuro), agua residual, el drenaje acido de mina y aguas pluviales.
Los ejemplos y documento anteriores presentan algunos de los riesgos de la
minería de oro, incluyendo derrames de cianuro, brechas y fugas en los diques
de colas, y efluentes con metales tóxicos y ácidos. Estos y otros riesgos están
ilustrados en figuras 1 a 7.
·
·
La figura 1 muestra un barranco en las colas que erosionó río abajo
después de una brecha en el dique de colas. Estas colas inundaron y
esterilizaron las milpas de los granjeros río abajo.
El fondo del valle estéril en la figura 2 debiera estar cubierto con arbustos
de sauce y pozas de castores; sin embargo, el área está contaminada con
colas tóxicas que también filtran al arroyo adyacente, matando la vida
3

acuática. Está contaminación ocurrió hace más de 100 años y el área
todavía no se ha recuperado.
Las colas en la figura 3 tienen de 20 a 80 años. Las colas nunca se
secaron completamente y los efluentes de metales tóxicos y ácidos se
filtraron al arroyo adyacente durante todo el período. Cuando se tomó la
foto, estaban en el proceso de quitar las colas hacia un vertedero seguro.
El tajo abierto en la figura 4 se llenó con agua superficial y agua
subterránea que se contaminó con los sulfuros y metales filtrados de la
roca mineralizada que se quedó en las paredes del tajo. Esta agua
contaminó el agua subterránea que salió a los arroyos cercanos. Tal
agua también se acumula en minas subterráneas y de una manera similar
se contaminan.
Una fuente de agua de una mina subterránea se muestra en la figura 5
donde el agua de color naranja es una descarga de metal tóxico y ácido
que se mezclan con agua pura.
La figura 6 muestra algunos de los más de 150,000 peces muertos por
una descarga imprevista de colas al arroyo, similar a las de la figura 3.
La figura 7 muestra una planta de tratamiento de agua de una mina con
estanques de lodo encima de colas anteriores. Periódicamente se
remueve la salida de lodo de la planta de tratamiento a un vertedero. La
planta de tratamiento ha operado desde que la mina cerró en los años
1970 y probablemente tendrá que operar perpetuamente.
Los riesgos de todas las calamidades mencionadas anteriormente existen en la
mina Marlin. También existen otros no mostrados en los ejemplos, el documento
y las fotos. Las tierras del sitio se erosionan fácilmente cuando son alteradas y
se les remueve la vegetación. Si las aguas superficiales no son controladas
cuidadosamente, ni el área es revegetada apropiadamente, podría erosionarse
considerablemente y como resultado las tierras no podrían usarse. Río abajo,
los suelos erosionados se decantan fuera del agua y llegan a ser sedimentos
que atascan los arroyos y cubren tierras adyacentes cuando son movilizadas por
el nivel alto del agua durante la temporada lluviosa. Si Montana abandona la
mina de manera súbita, quedarán en el sitio productos químicos peligrosos y
productos de petróleo que pueden ser vulnerables a descargarse en el medio
ambiente.
Cuando desastres como los anteriores ocurren, el gobierno, los residentes
locales y el medio ambiente son los que sufren las consecuencias. Los
ciudadanos que pagan impuestos tienen que financiar los costos de limpieza o la
tierra y gente local sufrirán daños severos y duraderos a la salud pública y al
medio ambiente. Debido a la historia de empresas mineras huyendo de tales
desastres, las autoridades deberían ser agresivas en forzar a las empresas
mineras en el cumplimiento de sus responsabilidades. Esto incluye que
requieran que la empresa minera aparte el costo total de la recuperación. La
sección siguiente provee un cálculo aproximado de los fondos que Montana
debería de proveer como fianza de garantía, en el evento que falle en completar

ESTIMACIÓN DE COSTOS DE LA RECUPERACIÓN
La estimación total de costos de recuperación es Q389 millones ($49 millones, el
tipo de cambio es de Q8.097 = $1.00), asumiendo que Montana se va de la mina
Marlin sin realizar la recuperación adecuada. Esto puede ocurrir si la empresa
abandona la mina, si la empresa se declara en bancarrota, o si la empresa cierra
por orden del gobierno (aún y cuando sea imprevisto). Esta estimación es el
total que el gobierno de Guatemala debiera requerir de Montana en unafianza de
garantía para realizar la recuperación de la mina si cualquiera de los sucesos
mencionados anteriormente llegara a pasar.
Si Montana no realiza la
recuperación adecuada, la fianza de garantía puede ser utilizada para recuperar
las tierras explotadas, proteger a la gente local y al medio ambiente de daños de
largo plazo, y volver las tierras explotadas a su uso anterior. La fianza de
recuperación actual de Marlin es $1 millón (Montana Exploradora de Guatemala,
S.A., 2010, p. 50).

Vale la pena resaltar que las tareas de recuperación que valen más incluyen:
·
·
·
·
Tratamiento de Agua Superficial para operación indefinida de la planta de
tratamiento de agua—total: Q96,776,222/$11,952,108
Roca estéril de minas & tajos abiertos y Colas son costos de movimiento
de tierra para renivelarlos taludes empinados y altos de los lados de los
tajos; y renivelar, cubrir y revegetar todas estas áreas—total:
Q104,121,694/$12,859,293
Sedimento & drenaje y Escollerado (ripio) para controlar erosión—total:
Q28,169,326/$3,478,983
Demolición y extracción de edificios, equipo, cables de alta tensión y
subestación—total: Q13,190,364/$3,478,983
Los altos costos de tratamiento de agua y movimiento de tierra reflejan el riesgo
más grande de la minería, que es la descarga de efluentes tóxicos. Los otros
costos son necesarios para devolver las tierras alteradas por la mina a su uso
anterior, que en este caso es agricultura y silvicultura.
La estimación de costos de recuperación puede ser reducida por recuperación
concurrente y salvamento de equipo. Aunque Montana está haciendo alguna
recuperación concurrente, los informes anuales de monitoreo no proporcionan
ningún detalle (Montana Exploradora de Guatemala, S.A., 2005-2009). Algunas
de las áreas que Montana pueda estar recuperando concurrentemente incluyen
alteraciones o disturbios de exploración, tajos abiertos y vertederos de roca
estéril de mina. Es posible que el equipo de minería y de procesamiento pueda
tener algún valor de salvamento y que pueda ser acreditado al costo de
recuperación. Sin embargo, ningún valor de salvamento del equipo se incluye
en la estimación de costos porque no es posible prever el estado del equipo
11
Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin

cuando la mina cierre. Es difícil dar un costo-ahorro preciso de cualquier
recuperación concurrente, ya que Montana no tiene ningún plan de recuperación
público, y los informes anuales de monitoreo son vagos en cuanto a la
recuperación completada a la fecha. Aún más importante, ninguna autoridad
independiente o gubernamental ha certificado la recuperación realizada hasta la
fecha ni la calidad del trabajo realizado.
Otra posibilidad para reducir costos sería en el costo de operación de
tratamiento de agua, si los efluentes de metales tóxicos y ácidos no se
desarrollan en los dos tajos abiertos, la mina subterránea y la roca estéril de
mina.
Partes de la fianza de recuperación podrían ser devueltas a Montana cuando la
recuperación sea completada y certificada o se demuestre que no es necesaria.
Puesto que Montana no tiene ningún plan de recuperación público ni planes que
muestran los límites finales de la minería y alteración de la tierra, el costo total
de recuperación estimado anteriormente se basó en gran parte en el cálculo
profesional y experiencia previa en minas similares. Una estimación de costos
basada en planes y mapas detallados, datos comprobados y análisis de
ingeniería puede resultar mucho más alta. Todas las tareas de recuperación son
vulnerables a un aumento en costos, si los parámetros de la evaluación de
costos están subestimados. Algunos de los artículos de recuperación que
pueden ser significativamente subestimados en esta estimación son la
suficiencia de la planta de tratamiento de agua existente para usos futuros; la
cantidad de efluentes tóxicos que se desarrollan de los trabajos de la mina, roca
estéril de mina y colas; el tiempo necesario para estabilizar las colas; y el trabajo
necesario para controlar la erosión y revegetar las tierras alteradas.
Montana también planea procesar la mena de otros proyectos cercanos en las
instalaciones de la mina Marlin. El impacto de esta actividad en los costos de
recuperación no está incluido aquí.
El cuadro 2 presenta un resumen de la estimación total de costos de
recuperación, basada en costos de los EE.UU. Estos son los costos ajustados
para las tasas de mano de obra y moneda para llegar a los costos en el cuadro
1. En el cuadro 1, la mano de obra está ajustada a un 15.66 por ciento de la
mano de obra de EE.UU. Este porcentaje se basa en la proporción de
Guatemala a EE.UU. del salario promedio mensual para minería y extracción
obtenida de la Organización Internacional del Trabajo (OIT) en
http://laborsta.ilo.org/. La tasa de cambio utilizada es Q8.097 por $1. Los costos
en Guatemala para equipo y suministros importados pueden ser más altos que
lo estimado. Por el otro lado, los suministros obtenidos localmente pueden ser
menos que lo estimado. La estimación total del cuadro 1 asume que estas
diferencias se compensan. Un ingeniero especializado en evaluación de costos
locales puede actualizar la estimación con tasas de costos unitarios locales. El

TAREAS DE RECUPERACIÓN
La recuperación propuesta en esta estimación de costos tiene el objetivo de
minimizar los impactos de la minería en la población local y el medio ambiente y
devolver las tierras alteradas a su uso anterior,lo más posible, dado el estado
actual de la tecnología para la recuperación. Por uso anterior se entiende
devolver tanto de la tierra como sea posible a la agricultura, pastoreo y
silvicultura. Asegurar que estas tierras vuelvan a sus usos anteriores puede ser
un proceso largo, quizás de quince años o más. Para devolver las tierras
alteradas a su uso anterior, se tienen que remover todas las instalaciones y
equipo superficial. Las tierras alteradas tienen que ser contorneadas a su
estado natural, cubiertas con medios de cultivo y revegetadas. Adicionalmente,
el agua superficial tiene que ser controlada para prevenir la erosión y los
subsiguientes daños por sedimentación pendiente abajo del riachuelo.
El mayor riesgo ambiental es la liberación de efluentes de metales tóxicos y
ácidos de los tajos abiertos (Marlin y Cochise), la mina subterránea, la roca
estéril de mina descargada en la superficie y las colas. El agua superficial y
subterránea pasa por la mineralización sulfurosa en la roca de la mina. El agua
disuelve los metales sulfurosos y se vuelve ácida. Este proceso generalmente
se define como drenaje ácido de roca (DAR). Hay dos defensas en contra del
DAR. La primera defensa incluye varias medidas de control de fuentes
diseñadas para prevenir la formación del DAR. La segunda línea de defensa es
recolectar cualquier DAR, sacar los componentes tóxicos en una planta de
tratamiento de agua y liberar el agua limpia a las vías fluviales cercanas. Los
lodos tóxicos recogidos por la planta de tratamiento de agua tienen que ser
retenidos en un vertedero en el sitio, diseñado por ingenieros calificados. Este
tratamiento puede ser necesario indefinidamente, como en el caso de minas
históricas donde el DAR se descarga por décadas y siglos después de
terminada la minería.
El control de fuente involucra bloquear los ingredientes en las reacciones
químicas que forman el DAR. En el caso de la mina Marlin, esto significa
bloquear el agua y oxigeno de contacto con minerales sulfurosos en la roca
dejada expuesta por la minería. Estos son dos de los ingredientes necesarios
para crear el DAR. Los métodos de control de fuente usados en esta estimación
de costos incluyen aplicar la cal en los suelos sulfurosos y la roca sulfurosa
expuesta, compactar tierras para minimizar la filtración de agua y desviar las
aguas superficiales lejos de estas áreas.Es muy difícil detener el DAR después
de que las reacciones químicas han iniciado, por lo que es probable que
cualquier medida de control de fuente sea exitosa solamente de manera parcial.
Las colas son una pulpa de roca finamente molida, químicos procesados y agua
de procesamiento que sobran después de que la planta de procesamiento haya
removido los minerales valiosos de la mena. El agua contiene los mismos
metales tóxicos que el DAR más algunos químicos de procesamiento. Las colas
14
Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin
- UUSC - COPAE-
están contenidas atrás de una presa y llenan un pequeño valle. El agua tóxica
de las colas puede derramarse durante tormentas y también continuamente
infiltrar agua subterránea ubicada inmediatamente gradiente abajo de la presa.
Debajo de la presa, hay pozos de agua subterránea que fueron construidos para
interceptar los efluentes tóxicos y bombear el agua tóxica a la poza. (Esta poza
es nombrada “poza de infiltración” por Montana.) Desde esta poza, el agua
tóxica capturada es bombeada de vuelta a las colas.
La segunda línea de defensa para prevenir la liberación de descargas tóxicas es
recoger cualquier DAR que pasa por las medidas de control de fuente, recoger
agua tóxica en las colas y el agua subterránea abajo del dique de colas y
procesar estas descargas en una planta de tratamiento de agua. Los lodos
removidos desde el agua tienen que ser retenidos en un vertedero a prueba de
filtraciones.
Montana construyó una planta de tratamiento de agua para
procesar las colas y extraer componentes tóxicos. Esta estimación de costos
asume que la planta de tratamiento de agua existente es adecuada para
necesidades futuras. La planta de tratamiento pudiera tener que operar
indefinidamente.

Q96,776,222/$11,952,108
Marlin ya tiene una fuente de descargas tóxicas y tres posibles fuentes que
pueden desarrollarse con el tiempo.
15
Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin
- UUSC - COPAE-
La fuente de descargas que existe (las colas) contiene aguas tóxicas. Esta agua
se está infiltrando al agua subterránea, en la parte debajo del dique de colas. (Etech, 2010; MEG 2009, p. 61; MARN 2008-2010, D6 samples; Robertson 2009,
p. 6,11) Actualmente Montana tiene pozos subterráneos que están bombeando
el agua contaminada a una poza y después de vuelta a las colas. Este bombeo
de agua probablemente debe continuar indefinidamente o hasta que ya no exista
más contaminación del agua subterránea. Si no se remueve por bombeo, la
pluma de agua subterránea contaminada se expandirá y eventualmente llegará a
nacimientos de agua o aguas río abajo. El agua debe ser tratada para que se
remuevan todos los componentes tóxicos, antes de devolverla a la corriente que
se encuentra río abajo. Además, el agua tóxica en las colas requiere de
tratamiento para poder completar la fase final de recuperación del área de las
colas. Los sólidos de las colas, no se están decantando del agua tóxica como
se esperaba (Robertson 2009, p. 6, 11). Para desaguar las colas, deben ser
tratadas para separar los sólidos del agua. El agua se debe tratar para remover
componentes tóxicos y luego ser liberada. Los sólidos separados deben ser
removidos a un vertedero en el sitio, diseñado por ingenieros calificados. El
tratamiento de la pluma de agua subterránea y las aguas de las colas puede
requerir de muchos años e incluso décadas.
Las otras tres posibles fuentes de descargas tóxicas son los tajos Marlin y
Cochise, la mina subterránea y la roca estéril de mina descargada en la
superficie. Todas estas instalaciones contienen rocas sulfurosas expuestas que
pueden filtrar efluentes de metales tóxicos y ácidos, también conocido como
drenaje ácido de roca (DAR). Montana informa que ha tomado medidas de
control de fuente para prevenir el DAR, como renivelarlos taludes empinados de
los tajos, colocar relleno cementado dentro de la mina subterránea en las partes
donde se ha sacado la mena, encapsular cualquier roca estéril sulfurosa
profundamente dentro de roca estéril neutral y colocar una capa de suelo sobre
la roca estéril de mina. Sin embargo, estos pasos son notorios por tener un éxito
limitado. En las tareas de recuperación que se encuentra más adelante, se
proveen pasos de control adicionales para minimizar el riesgo del DAR. Si estas
medidas no tienen éxito, el DAR necesitará de tratamiento indefinidamente.
Esta tarea de recuperación hace provisión para operar la planta de tratamiento
de agua de manera indefinida, para tratar efluentes del dique de colas y agua
tóxica contenida en las colas y posiblemente el DAR. El software que estima
costos no incluye el estimado para el tratamiento de agua. Además, Montana no
ha hecho públicos los detalles de la planta de tratamiento de agua a partir de los
cuales se podría estimar los costos.
Costos de operación para el tratamiento de agua generalmente varían entre $1 a
$4 por mil galones de agua tratada. Si se asume una tasa razonable de $1.50
por mil galones para el tratamiento de agua en la mina Marlin, los costos de
operación son:
16
Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin
- UUSC - COPAE-
1. Costo total para tratar el agua en las colas:
$4,800,000 según los 20 millones de metros cúbicos de colas
(Howell&Christopherson, 2009) con contenido (la densidad de las colas
es de 1 tonelada métrica por metro cúbico) (Robertson, Montana
Exploradora de Guatemala, 2009 Annual Monitoring Report, Appendix E,
p. 11)
2. Costo anual para el tratamiento de agua subterránea y DAR:
$394,200 anuales, asumiendo que se necesita el tratamiento de 500
galones por minuto de agua subterránea contaminada y DAR. Una
cuenta de banco en custodia con un interés de seis por ciento de interés
anual, requeriría de $6,570,000 para pagar los costos anuales de
operación
Si la planta debiera ser operada indefinidamente, se necesitará de fondos
adicionales para reemplazar el equipo viejo. El costo típico de una planta de
tratamiento de agua como la que tiene la mina Marlin, es de alrededor de $5
millones, sin incluir los costos de diseño e ingeniería. Proveer la mitad del
monto, para reemplazar equipo viejo con el tiempo, requerirá de $2.5 millones.
No se necesita proporcionar totalmente el costo de construcción inicial de $5
millones puesto que mucho de este costo original incluye fondos para artículos,
los cuales no necesitarán ser reemplazados, como la preparación del sitio y los
cimientos.
El monto total requerido para la fianza de recuperación para el tratamiento de
agua es de $13,870,000, las tres cantidades resaltadas en negrita previamente.

Montana ha perforado y continúa perforando agujeros de exploración en varios
depósitos minerales para tomar muestras de mena posible. Estas perforaciones
han ocurrido más en particular en Marlin, la Hamaca y West Vero. Cualquier
revestimiento de las perforaciones debe ser removido. Las perforaciones deben
ser rellenadas en todo su largo para prevenir el entrecruzamiento de acuíferos
que hayan sido penetrados por las perforaciones, así como para prevenir
posibles daños a las personas y animales que puedan tropezarse en las
perforaciones. La estimación de costos provee para el taponamiento de las
perforaciones con lechada de cemento. También existen un número de pozos
que proveen de agua, y pozos de monitoreo que deben ser rellenados de
manera similar, durante la fase final de la recuperación.
El número de perforaciones en las principales áreas de exploración y sus
profundidades se encontraron en diferentes fuentes, sin embargo, existe poca
información sobre el largo del revestimiento en ellas y la profundidad a la que el
agua fue encontrada. Esta información fue asumida.

Los caminos de acceso, bancadas de perforación y sumideros de exploración
deben ser renivelados a formaciones de terreno natural, cubiertos con medios de
cultivo y revegetadas. No se obtuvo información sobre caminos de acceso y
bancadas para perforación en La Hamaca y West Vero, esta información tuvo
que ser asumida. El largo y ancho del camino de acceso hasta los pozos que
proveen de agua se obtuvo de un mapa de Marlin (Comisión Gubernamental
para Analizar el Fenómeno de Agrietamiento de Paredes en Algunas Casas
Adyacentes al Proyecto Minero Marlin I, 2010). El costo de recuperación para
caminos de acceso dentro del área del proyecto Marlin se incluyen en Caminos.
Es posible que Montana haya completado parte de este trabajo de recuperación.
Sin embargo, hasta que el trabajo esté certificado como completado
adecuadamente, cualquier fianza de garantía para la recuperación debiera
proveer para hacer el trabajo.
Caminos
Q6,161,957/$761,017
Hoja de Cálculo: Roads (Caminos)
Los caminos que requieren recuperación incluyen los caminos muy anchos de
acarreo desde los tajos abiertos de Marlin y Cochise a la trituradora y
escombrera de roca estéril de mina, pista de aterrizaje y otros caminos en el
sitio. Estos caminos deben ser renivelados a formaciones de terreno natural,
cubiertos con medios de cultivo y revegetados. La pista de aterrizaje está

Tratamiento de Cal para Tajo
Q777,536/$96,028
Hoja de Cálculo: MiscellaneousCosts (Costos Misceláneos)
Se debe aplicarla cal a la roca sulfurosa en los tajos abiertos para neutralizar
cualquier producto de lixiviación de metales tóxicos y ácidos que pueda formar.
Los costos estimados, asumen que se aplican 10 toneladas por acre (Skousen&
McDonald, 2005) sobre un área de 65 acres (263,045 mt2). Este cálculo (área
de acres) asume que mucha de la superficie del tajo es de roca sulfurosa.
Puede que este no sea el caso, y un análisis detallado por un ingeniero
profesional e independiente puede resultar en un cálculo menor de acres.
Adicionalmente, puede ser que exista roca carbonática que ayude a neutralizar
el sulfuro.
Desagüe de Tajos
Q1,398,771/$172,752
Hoja de Cálculo: Miscellaneous Costs (Costos Misceláneos)
La renivelación del talud del tajo Marlin puede dejar una depresión en el fondo
del tajo en donde se puede acumular el agua que puede llegar a ser
18
Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin
- UUSC - COPAE-
contaminada por efluentes de metales tóxicos y ácidos. Cuando esta agua se
eleve hasta el punto más bajo del borde de la depresión, el agua empezará a
derramarse en la ladera del sur, arriba del río Tzalá. La estimación de costos
incluye el corte de una trinchera desde el fondo del tajo hasta la ladera periférica
que se encuentra hacia el sur; instalar una alcantarilla con un tubo elevado
perforado en el fondo del tajo y rellenar la trinchera. Esta alcantarilla drena
cualquier acumulación de agua en el fondo del tajo hasta una poza de revestido
desde donde se bombea a la planta de tratamiento de agua. La poza debe tener
un revestimiento geo-sintético adecuado para prevenir la filtración de los
efluentes de metales tóxicos y ácidos ya desde la poza.
La estimación de costos se basa en una poza (incluido en Control de Sedimento
y Drenaje) con una capacidad y una bomba con velocidad de bombeo adecuado
para tratar en caso de una tormenta de 24 horas como los últimos 100 años, con
precipitación de 219 milímetros (Robertson, 2009, p.9) sobre 65 acres (263,045
mt2). La estimación de costos provee para una bomba de velocidad de 500
galones por minuto y una tubería de distribución de 6,600 pies de largo con una
carga de agua de 200 pies. Es posible que este desagüe del tajo se requiera
indefinidamente. El desagüe de tajo similar, no se incluye para el tajo abierto
Cochise ya que va directamente a un drenaje que fluye a las colas. Cuando las
colas han sido tratadas y recuperadas, será necesario construir una tubería
desde el tajo abierto Cochise hasta la planta de tratamiento de agua si este tajo
abierto comienza a descargar los efluentes de metales tóxicos y ácidos.
Aberturas Subterráneas
Q81,582/$10,076
Hoja de Cálculo: Underground Openings (Aberturas Subterráneas)
La mina subterránea tiene dos aberturas hacia la superficie: una rampa
descendente y una chimenea de ventilación. La estimación de costos provee
para un tapón de concreto y roca en la portal descendente y una tapadera de
concreto para la abertura de la chimenea de ventilación.
Agua de la Mina Subterránea
Cuando la mina cierre, existe el riesgo de que los trabajos subterráneos sean
llenados con agua que pueda acumular efluentes de metales tóxicos y ácidos
provenientes de rocas sulfurosas que están alrededor. Subsecuentemente esta
agua tóxica puede migrar al agua subterránea y después a los manantiales de
agua superficial y ríos. Como Montana está rellenando algunas áreas de la mina
con roca estéril de mina cementada, el cemento está tamponando cualquier
ácido que se forma actualmente. Este proceso de tamponar quizás no dure en
el largo plazo, y por eso se incluyen dos tareas de recuperación para minimizar
el riesgo de una descarga de metales tóxicos y ácidos.
Tratamiento subterráneo con cal
Q621,322/$76,735
Hoja de Cálculo: Miscellaneous Costs (Costos Misceláneos)
Se debe aplicar cal en los trabajos subterráneos para neutralizar cualquier

19
Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin

del agua de la mina se calcula es de 1.1 millón de metros cúbicos, el cual
es el volumen estimado de los trabajos del desarrollo subterráneo en el
momento en que se ejecute el cierre planeado de la mina. Este volumen
no incluye las áreas en donde será o ha sido removida la mena, ya que
Montana está rellenando estas áreas con roca estéril de la mina
cementada. La cantidad de cal se estima en base al agua de la mina, la
cual tiene 500 miligramos de sulfato por litro (Montana Exploradora de
Guatemala S.A., 2007, p. Ann. C, D1) y una eficiencia de neutralización
de cal de 0.82 (Skousen, Hilton & Faulkner, 2010).
Desagüe de Mina Subterránea
Q762,966/$94,228
Hoja de Cálculo: Miscellaneous Costs (Costos Misceláneos)
En el caso de que la aplicación de cal antes mencionada, resulte
inadecuada, la estimación de costos hace provisión para la perforación de
un hoyo (pozo de agua) desde la superficie hasta un sumidero en el punto
más bajo de los trabajos para desaguar la mina. La perforación debe ser
equipada con tubo y bomba sumergible dentro del pozo, ambos
resistentes al ácido, para remover efluentes de metales tóxicos y ácidos
desde la mina a la planta de tratamiento de agua. La velocidad asumida
es de 150 galones por minuto con una carga de agua de 475 metros.
Este desagüe y tratamiento de agua podrían ser requeridos
indefinidamente.
Pozas de Procesos
Q1,669,259/$206,158
Hoja de Cálculo: Process Ponds (Pozas de Procesos)
Existen tres pozas de proceso que requieren de recuperación. La primera es
para almacenar agua bombeada de los pozos que proveen agua; la segunda es
de sedimento, al sur del tajo Marlin; y la tercera es una poza de infiltración para
agua subterránea contaminada bombeada desde abajo del dique de colas.
Montana planea una segunda instalaciónde colas (Robertson, 2009, p.4) y la
estimación de costos incluye la recuperación de una poza de infiltración
adicional para la segunda instalación. Esta hoja de cálculo no incluye ninguna
poza construida para el control de sedimentos y la recuperación final. Estas
pozas se incluyen bajo Control de Sedimento y Drenaje.
Roca Estéril de Mina y Tajos Abiertos
Q48,464,409/$5,985,477
Hoja de Cálculo: Waste Rock Dumps (Escombreras de roca estéril)
Montana ha declarado que la escombrera de roca estéril de mina en uso actual
está siendo recuperada concurrentemente. Sin embargo, los informes anuales
de monitoreo no proveen ninguna información específica sobre esta
recuperación y no existe certificación independiente de que esta recuperación ha
sido completada apropiadamente. La estimación de costos provee para la
renivelación de los lados empinados de la escombrera de roca estéril de mina
hasta una pendiente más plana, de máxima horizontal a vertical a razón de 2.5:1
para minimizar la erosión y promover la revegetación. Las áreas reniveladas
deben ser compactadas, cubiertas con medios de cultivo y revegetadas. La
20
Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin
- UUSC - COPAE-
reducción de pendiente reduce el riesgo de erosión. La compactación reduce el
riesgo de que el agua superficial infiltre dentro de la escombrera donde pueda
reaccionar con la roca sulfurosa de la escombrera, produciendo efluentes de
metales tóxicos y ácidos.
De manera similar, los taludes empinados de los tajos abiertos deben ser
renivelados hasta una pendiente más plana, de máximo horizontal a vertical a
razón de 2.5:1, para minimizar la erosión de las superficies finales delos tajos
abiertos y para promover la revegetación sostenible. Aunque el nombre de esta
hoja de cálculo refiere solamente a las escombreras de roca estéril, los cálculos
de movimiento de tierra también son aplicables al removimiento de tierra de los
taludes empinados de los tajos, de la pendiente actual hasta una pendiente más
plana requerida. La estimación asume que el movimiento de tierra no requiere la
voladura.
Existe otra escombrera de roca estéril de mina que se llama “Área 5.” Esta
escombrera ya no es utilizada y ha sido cubierta. Una muestra de agua de esta
área demuestra poca contaminación en los efluentes de la roca estéril de mina
(Ministerio de Ambiente y Recursos Naturales, 2007). La estimación de costos
provee sólo para cubrir y revegetar esta área, la cual se encuentra bajo Patios.
Vertedero
Q343,439/$42,416
Hoja de Cálculo: Landfill (Vertedero)
Marlin tiene un vertedero de desechos sólidos para desechos no peligrosos que
requiere cierre y recuperación cuando la mina cierre. Cualquier material de
construcción que no haya sido salvado en la demolición de las estructuras
también debe de ser depositado en este vertedero.
Colas
Q55,657,285/$6,873,815
Hoja de Cálculo: Tailings (Colas)
Las instalaciones de colas existentes alcanzarán su capacidad máxima a menos
de un año (Robertson, 2009, p.4) y se requerirá una segunda instalación para
colas futuras. La estimación de costos provee para la recuperación de las colas
existentes y una segunda instalación de colas de dimensiones similares. Esta
estimación puede subestimar los costos de recuperación, debido a que la nueva
instalación de colas puede tener una capacidad de almacenamiento mayor que
la instalación existente.
La estimación de costos se basa en cubrir las colas, primero con una capa de
suelo de baja permeabilidad, compactada, de 24 pulgadas de espesor. La
segunda es una capa para drenaje, de 12 pulgadas de espesor. La tercera
capa, o capa superior de la cubierta de las colas es de medios de cultivo, de 24
pulgadas de espesor (United States Environmental Protection Agency, 1989,
p. 9). Esta capa es más espesa que la capa para la escombrera de roca estéril
de mina, los tajos abiertos y los patios porque las colas son tóxicas y deben ser
separadas del medio ambiente cuidadosamente.

Pueden pasar años o décadas antes de que las instalaciones de colas
existentes puedan ser finalmente recuperadas. Las partículas sólidas en las
colas no se están asentando del agua con la velocidad esperada (Robertson,
2009, p. 6, 11) y la superficie posiblemente no volverá a ser suficientemente
sólida para ningún trabajo por un largo tiempo. La operación de la planta de
tratamiento de agua facilitará el desagüe de las colas. Adicionalmente, se está
considerando un plan para desaguar colas futuras por filtración, y
alternativamente, una cubierta de agua para las colas ha sido sugerida
(Robertson, 2009, p. 3).
La presa de colas existente se está asentando más de lo esperado,
aproximadamente un tres por ciento hasta la fecha (Robertson, 2009, p. 13). La
estimación de costos provee para añadir dos aumentos de nivel, ambos de 100
pulgadas (tres por ciento de la altura de la presa) encima de la presa para
mantener su altura diseñada.

A pesar de que sea posible que la municipalidad o algunas organizaciones
quieran utilizar algunas de las construcciones después de que termine la
minería, la estimación de costos se ha hecho para remover las construcciones
ya que no existe certeza de que se conservaran. Podría existir algún valor de

La estimación de costos es adecuada para incluir la
caracterización química de cualquier suelo que haya sido contaminado con

Control de Drenaje de Sedimentos
Q2,382,529/$294,248
Hojas de Cálculo: Sediment and Drainage Control (Sedimento y Control de
Drenaje), Miscellaneous Costs (Costos Misceláneos)
Para minimizar la erosión y el riesgo de efluentes de metales tóxicos y ácidos, la
estimación de costos hace provisión para zanjas perimetrales para desviar el
agua superficial para que no fluya sobre los tajos abiertos renivelados, las
escombreras de roca estéril y las colas. Todas estas zanjas drenarán hacia
pozas de sedimento en las que se decantan el sedimento llevado por el agua.
La zanja perimetral del tajo Marlin es de dos secciones, una en torno del término
oriental y la segunda en torno del término occidental, con una poza al término de
ambas secciones. Mientras que, para las colas existentes, se encuentran dos
pozas de sedimento bajo del dique de colas, la estimación de costos provee
para la reconstrucción de ambas pozas. Las pozas actuales quizás no sean
funcionales cuando cierre la mina. Las pozas de sedimento requerirán la
extracción de sedimentos atrapados periódicamente.
Debido a que la escombrera de roca estéril tiene un talud muy largo, la superficie
debe tener zanjas de contorno paralelas espaciadas uniformemente a través del
tope y los lados. Esta desviación minimiza la formación de riachuelos y
barrancos en la escombrera y también minimiza la infiltración de agua por
precipitación directa. Estas zanjas deben ser revestidas de concreto (véase la
hoja de cálculo Miscellaneous Costs (Costos Misceláneos) para el revestimiento
de concreto como fue recomendado por Robertson (2009, p. 15).
El
espaciamiento entre las zanjas de contorno paralelas debe ser de 50 metros
horizontales.
Estas zanjas fluirán en las zanjas perimetrales descritas
anteriormente.
Los costos unitarios del revestimiento de concreto fueron
obtenidos de la guía RS Means Building Construction Cost Guide (1999, p. Sec.
033 130 4840).
La poza de sedimento oriental del tajo Marlin realiza una doble función,
recibiendo el agua desde la zanja perimetral oriental y el agua drenada desde el
fondo del tajo (véase Desagüe de Tajo). La poza debe ser revestida con un
revestimiento geosintético adecuado en caso que las aguas del fondo del tajo
desarrollen los efluentes de metales tóxicos y ácidos.

desechos radioactivos. El incinerador tiene una capacidad de 400 libras por
hora (Montana Exploradora de Guatemala S.A. 2006). Los costos unitarios

Hoja de cálculo: Miscellaneous Costs (Costos Misceláneos)
El cerco existente alrededor de los límites del proyecto debe ser removido y un
cerco nuevo debe ser instalado. El nuevo cerco tendrá un perímetro más
pequeño, cubriendo solamente las colas, la planta de tratamiento de agua y la
poza de sedimento oriental del tajo Marlin. El nuevo cerco protegerá estas áreas
contra cualquier intrusión pública hasta que se cierre finalmente y se termine su
recuperación. La recuperación final de estas instalaciones se espera que sea
completada mucho tiempo después que el otro trabajo de recuperación.
Extracción de tubería
Q1,182,418/$146,031
Hoja de Cálculo: Miscellaneous Costs (Costos Misceláneos)
Las tuberías terrestres que deben ser removidas son las tuberías que proveen
agua desde los pozos de abastecimiento a la poza de agua cruda, tuberías entre
la planta de procesamiento y ambos, la instalación de colas hasta las colas y
nueva tubería incluida en esta estimación de costos, desde la poza de
sedimento oriental del tajo Marlin a la planta de tratamiento de agua. El largo de
las tuberías hasta la instalación existente, ha sido doblado en la estimación de
costos para incluir el costo de la extracción de las tuberías hasta la nueva
instalación de colas.
El costo de demolición de estructuras se supone que es adecuado para incluir la
eliminación de cualquier tubería dentro y alrededor de las varias estructuras.
Tendido Eléctrico y Subestación
Q879,351/$108,602
Hoja de Cálculo: Miscellaneous Costs (Costos Misceláneos)
La estimación de costos incluye la extracción de dos líneas de tendido eléctrico y
una subestación. Una línea de tendido eléctrico es de alto voltaje entrante que
llega desde la planta eléctrica de Tejutla. La segunda línea de tendido eléctrico
es una línea de menor voltaje hacia los pozos que proveen agua.
El costo estimado de demolición de estructuras se supone que es adecuado
para incluir la extracción de la distribución de electricidad que se encuentra en el
sitio.

Escollerado
Q25,786,797/$3,184,735
Hoja de Cálculo: Miscellaneous Costs (Costos Misceláneos)
La estimación de costos provee para revestir todas las zanjas perimetrales de
desviación y los derramaderos de las pozas de sedimento con escollerado
(ripio).
El escollerado protegerá la integridad de las zanjas y de los
derramaderos por largo tiempo. La roca en la fachada y en el derramadero de la
presa del dique de colas se encuentra alterada por exposición a la intemperie y
se está degradando (Robertson, 2009, p. 5, 10). La estimación de costos
también hace provisión para la colocación de escollerado en estas superficies.
Ya que la roca en el sitio es inadecuada para escollerado, la estimación de
costos asume que la fuente del escollerado está afuera del sitio.Estas tareas de
recuperación no están incluidas para la nueva instalación de colas ya que se
asume que esta instalación será construida adecuadamente.
Monitoreo
Q6,419,407/$792,813
Hoja de Cálculo: Monitoring (Monitoreo)
La estimación de costos provee para monitorear roca estéril de mina (incluyendo
el “Área 5”), vertederos, colas y diques de colas, revegetación, agua subterránea
y superficial y cualquier efluente tóxico por un período de quince años. Esta
tarea requiere de lo siguiente:
· Muestreo y análisis de roca estéril de mina y colas, así como de agua
subterránea y superficial para medir contaminantes.
· Medición de la integridad y estabilidad de las escombreras de roca estéril
de mina, vertederos, colas y diques de colas con inclinómetros y
monumentos de agrimensura.
· Muestreo de colas para la densidad y el contenido de humedad.
· Muestreo de revegetación para la densidad y la riqueza de especies.
· Inspección para la erosión y sedimentación.
La tarea incluye interpretar e informar los resultados del monitoreo a las
autoridades y partes interesadas. La estimación de costos para esta tarea no
incluye el monitoreo de la planta de tratamiento de agua mencionada
anteriormente ya que se incluye en los costos de operación de la misma.
Administración de Construcción

cumplimento de la recuperación por parte de las agencias gubernamentales que
lo supervisarán, el cual en este caso irá al MEM y al MARN.
METODOLOGÍA DE LA EVALUACIÓN DE COSTOS
La estimación de costos de recuperación fue preparada con un programa de
Excel desarrollado conjuntamente por el estado de Nevada (EE.UU.), otras
agencias gubernamentales de los EE.UU. y la industria minera (Nevada Division
of Environmental Protection, 2010). El nombre del programa es Standardized
Reclamation Cost Estimator (Estimador Estandarizado de Costos de
Recuperación) (SRCE, por sus siglas en inglés), más información sobre el
software está disponible en el sitio web:
http://www.nvbond.org/index.htm
SRCE tiene las siguientes ventajas:
·
·
·
·
Es específico para la industria minera,
Es aceptado tanto por el gobierno como por la industria,
Utiliza tasas de costo actualizadas, y
Está disponible inmediatamente en la página web mencionada
anteriormente.
Existen otros programas de software para estimar los costos de recuperación,
incluyendo RACER (U.S. Air Force & U.S. Environmental Protection Agency,
2008) y Sherpa (Aventurine Engineering, Inc., 2010). La Agencia de Protección
Ambiental de los EE.UU. y la Fuerza Área de Estados Unidos desarrollaron
RACER para calcular los costos de recuperación para todo tipo de sitios con
materiales peligrosos.
Este programa requiere la introducción de datos
específicos que Marlin no tiene disponibles al público. Sherpa tiene una
reputación excelente y su autor provee además de un servicio de evaluación de
costos mineros que es usado ampliamente por la industria minera. A principios
de los años 90 la Agencia de Minas de los EE.UU. publicó una guía de
estimación de costos de minería la cual incluye recuperación y costos de
tratamiento de agua (U.S. Bureau of Mines).
La versión específica del programa SRCE y las tasas de costo utilizadas aquí se
encuentran en la portada de la estimación de costos (véase Anexo). Los datos
de entrada sobre las dimensiones para el programa SRCE se obtuvieron de
varias fuentes de Montana, las cuales están enumeradas en la sección de Obras
Citadas en este informe. Las notas que se encuentran después de los datos de
entrada en las hojas de cálculo de SRCE indican referencias específicas para la
información. En los casos en que la información de Montana está incompleta los
autores se basaron en su experiencia y juicio profesional para calcular los datos.
26
Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin
- UUSC - COPAE-
La estimación de costos elige equipo para remover tierra, de tamaño pequeño a
mediano en vez del equipo de gran escala usado por Montana. Esta selección
asume que un contratista local con equipo de tamaño típico para la construcción
de caminos será el encargado de realizar la recuperación, ya que es posible que
el equipo de Montana no esté disponible o en condiciones de operar en el
momento de la recuperación.
La estimación de costos utiliza tasas de unidades de costos de los Estados
Unidos. Los costos totales se ajustan a las tasas de trabajo local, convertidas a
quetzales, utilizando el factor de conversión al momento de preparación de la
estimación de costos. Para una estimación de costos más precisa, un estimador
profesional guatemalteco, podría ajustar las tasas de costo unitario utilizadas
aquí, a las tasas locales.
El programa SRCE no provee específicamente para la evaluación de costos de
todas las tareas de recuperación requeridas en Marlin. En particular, no tiene
hojas de cálculo para renivelar tajos abiertos, tratar aguas tóxicas y operar el
incinerador de desechos peligrosos. Para renivelar los tajos abiertos fue posible
adaptar la hoja de cálculo de Waste Rock Dumps (Escombreras de Roca
Estéril). Para el tratamiento de agua y la incineración, SRCE se complementó
con fuentes de estimaciones y publicaciones profesionales.
Es muy posible que existan defectos en la estimación de costos. Muchos de los
datos de entrada se obtuvieron del Estudio de Evaluación de Impacto Ambiental
y Social de Marlin (Montana Exploradora de Guatemala, S.A., 2003). Este
documento ahora está desactualizado siete años y algunos de los datos
necesarios para los propósitos de la evaluación de costos están incompletos.
De la misma manera, hay datos que se obtuvieron de los informes anuales de
monitoreo (Montana Exploradora de Guatemala, S.A., 2005-2009), los cuales no
son muy adecuados para realizar estimaciones de costos como las mediciones
de campo efectivas y planos de ingeniería detallados. Además, algunas
dimensiones fueron tomadas de un mapa de un informe gubernamental
(Comisión Gubernamental para Analizar el Fenómeno de Agrietamiento de
Paredes en Algunas Casas Adyacentes al Proyecto Minero Marlin I, 2010). La
mayor incertidumbre está en el costo futuro del tratamiento de agua tóxica en las
colas y posiblemente de efluentes con metales tóxicos y ácidos producto de los
trabajos de la mina y de roca estéril de mina descargada en la superficie.
Otra estimación de costos de recuperación es de $13.06 millones (On Common
Ground, 2010, p.13). La empresa MWH Consulting preparó esa estimación de
costos para Goldcorp en mayo del 2009.
Una revisión profesional e
independiente concluye que la estimación de costos es baja, el período de cierre
es corto y que no hay fianza de garantia para asegurar la recuperación (On
Common Ground, 2010, p. 12-14). Otros profesionales expertos en riesgo de
minas han señalado que la fianza de garantia de US$1 millon es muy baja (ETech, 2010) Aparte de su resumen en la revisión mencionada, la estimación de
27
Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin

costos de MWH Consulting no está disponible al público y no ha pasado la
prueba de escrutinio público. Tampoco la estimación no ha sido analizada ni
evaluada por una autoridad capacitada e independiente. Sería muy útil revisar la
estimación de costos de MWH Consulting con atención especial a los métodos y
presunciones utilizadas.

REQUERIMIENTOS PARA EL PLAN DE RECUPERACIÓN
Se ha informado que existe un plan de recuperación por parte de la mina Marlin
(On Common Ground, 2010, p. 13); sin embargo, no está disponible al público.
Si se hiciera público, las tareas y los costos de recuperación podrían ser
comparados con esta estimación, para corrobar si ese plan está o no está
completo y si sus estimaciones de costos son aceptables o no. Se supone que
los autores de dicho plan tuvieron mejor acceso a la información de Marlin. O,
los datos de entrada para esta estimación de costos pueden ser ajustados según
sea apropiado. De hacer esto, debe tenerse mucho cuidado de aceptar
solamente información, que sea más precisa, y que haya sido certificada
independientemente por una autoridad reconocida.
En el diseño de planes de ingeniería existen varios niveles de detalle posible,
incluyendo en complejidad cada vez mayor: 1) magnitud de orden, 2)
conceptual, 3) diseño, y 4) construcción. Un plan de recuperación de una mina
debiera estar al nivel más alto de construcción, siendo este, el nivel más
detallado. Esto significa proporcionar criterios de ejecución, especificaciones,
restricciones, cantidades y planos de ingeniería con detalles suficientes para la
construcción. Las alteraciones actuales y las alteraciones finales planificadas a
la tierra en Marlin debieran ser mostradas en una escala mayor que 1:200, y
estos planos debieran ser actualizados cada vez que se den cambios. Los
planes de movimientos de tierra debieran ser mostradas en la misma escala y
los detalles en estos planes, como zanjas, pozas, cercos, etcétera, debieran ser
mostrados en una escala adecuada para la construcción. Para los varios
edificios e instalaciones de procesamiento, los planos de construcción originales,
actualizados con alguna modificación posterior, son adecuados. Además, es
vital que el plan de recuperación tenga informes detallados sobre los varios
recursos naturales, incluyendo agua subterránea y superficial, geología y
mineralogía, suelos, fauna y vegetación. Estos informes deben describir el
estado de los recursos previo a empezar la minería, cómo la minería impactará a
estos recursos y medidas de mitigación para prevenir su degradación. Para
cualquier posible efluente de proyecto, los informes deben demostrar sus
fuentes, rutas de liberación y todos los posibles receptores ambientales y
humanos. Los informes deben incluir mapas de los recursos; muestreo y datos
analíticos; densidad poblacional y estadísticas de distribución.
Lo más
importante, el plan de recuperación de la mina debe incluir planes de manejo
para proteger los recursos y mitigar los impactos del proyecto.
Para tener un ejemplo de los requerimientos de un plan de recuperación de una
mina, se pueden ver las reglas y regulaciones del estado de Colorado, EE.UU.
en la siguiente página web:
http://mining.state.co.us/Rules%20and%20Regs.htm
29
Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin
- UUSC - COPAE-
Esta página web también tiene los planes de recuperación para minas en
Colorado. Por ejemplo, la mina de oro de San Luis era de tamaño similar a la
mina Marlín, con una producción diaria de mena de 5,000 toneladas y una vida
de 10 años. El plan de recuperación es de cerca de 700 páginas en forma de 17
documentos como pruebas y tres anexos. El archivo incluye otros 170
documentos de audiencias públicas, revisiones y correspondencia sobre el plan
de recuperación. Después de haber presentado el plan original, alrededor de
1,790 revisiones se registraron en el mismo, durante la vida de la mina. La
administración del plan de recuperación por parte del estado se informa en 55
documentos sobre la fianza de recuperación, 120 inspecciones y 471
documentos de aplicación de la ley (Colorado Division of Reclamation, Mining &
Safety, 2010).
Existen varias referencias internacionales o puntos de partida que podrían
ayudar a los reguladores guatemaltecos a desarrollar un programa de
recuperación de minas. El Grupo del Banco Mundial tiene información sobre
directrices de minería, cierre de minas y fianzas de garantía (International
Finance Corporation, 2007) (Sasson, 2009) (Sheldon, et al, 2002). Uno de los
contratistas de ingeniería de Montana, SPK Consulting, publicó un documento
llamado “Overview of International Mine Closure Guidelines” (Perspectiva
general de directrices internacionales para cerrar una mina) (Garcia, 2008).En
Marlin las colas son uno de los principales temas de recuperación. El sitio web
siguiente tiene información técnica y directrices sobre colas.
www.tailings.info/guidelines.htm
Un recurso técnico muy respetado, es el programa canadiense Mine
Environment Neutral Drainage, el cual se puede encontrar en
http://www.nrcan.gc.ca/mms-smm/tect-tech/sat-set/med-ndd-eng.htm
Los reguladores guatemaltecos debieran ser diligentes en exigir un plan de
recuperación comprensivo para Marlin y debieran ser diligentes en hacer que el
mismo se cumpla. Goldcorp no tiene un muy buen récord de protección
ambiental en muchas de sus minas, como se demuestra a continuación:
·
·
·
·
·
Alumbrera, Argentina: derrame de pulpa en tubería; liberación de
transporte de nitrato de amonio; liberación de arsénico, cadmio, cobre,
mercurio y estroncio.
Red Lake, Canadá: liberación de colas en el canal Bruce de Red Lake, la
cual requirió de cerrar por dos días la cercana planta municipal de
tratamiento de agua; se encuentra dentro de los 12 mayores emisores de
arsénico de toda Canadá.
Musselwhite, Canadá: liberación de cianuro.
EquitySilver, Canadá: drenaje ácido de roca.
La Coipa, Chile: liberación de mercurio y cianuro.

(MiningWatch Canada, 2007)
Si no se cuenta con vigilancia por parte del gobierno de Guatemala, las
municipalidades de San Miguel Ixtahuacán y Sipacapa, así como la población
local, la mina Marlin tiene el potencial de dejar un legado sumamente costoso
así como una fuente de continuos problemas ambientales durante muchos años
futuros.

CONCLUSIONES
Desde múltiples puntos de vista, la actual fianza de recuperación de $1 millón
que tiene Marlin, es insignificante.
·
·
·
·
La estimación de costos en este informe indica que los costos de
recuperación en el caso de que Montana esté en incumplimiento pueden
ser de hasta Q389 millones o $49 millones.
Existe una alta probabilidad que efluentes contaminados del sitio
requieran tratamiento de agua por tiempo indefinido (E-Tech, 2010). El
total mencionado anteriormente incluye suficientes fondos para una
cuenta en custodia de Q97 millones o $12 millones para financiar el
tratamiento.
Las fianzas de recuperación de otras minas modernas en otros lugares,
son del mismo orden de magnitud que el monto estimado en este
documento.
Un informe no publicado, preparado para Montana estima los costos de
recuperación en $13.06 millones. Aún así, otro experto en minas, quien
ha revisado la estimación de $13.06 millones, concluyó que es
inadecuada (OnCommonGround, 2010).
Al no contar con una fianza de recuperación adecuada, Guatemala se encuentra
expuesta a altos riesgos ambientales y a la salud pública, en el caso de que
Montana no cumpla con su responsabilidad de recuperar la mina Marlin
adecuadamente. Tal incumplimiento por Montana podría ser un resultado de
bancarrota, cierre forzado de forma planificada o no planificada, y climas
extremos o eventos sísmicos.
Un plan de recuperación que no está disponible al público, como el cual se
informa que tiene Marlin, es igual de serio (On Common Ground, 2010).
Despierta dudas sobre la sinceridad de la empresa minera y los reguladores. A
nivel mundial estos documentos están obligados a ser públicos. El público
puede ser un recurso valioso en asegurar que los proyectos industriales sean
conducidos de una manera apropiada.
El paisaje mundial está lleno de minas que impactan adversamente la salud
pública y el ambiente. Muchas de estas son minas históricas, pero también hay
empresas mineras modernas que son irresponsables y continúan causando
desastres ambientales tal como se aprecia en la corta lista mencionada en la
sección de Riesgos Ambientales de la Minería. Muchos de estos desastres son
monumentales debido a que la minería moderna se desarrolla a escala masiva.
Algunos de estos desastres requieren de cientos de millones o más de mil
millones de dólares en fondos del gobierno para limpiar el sitio y a pesar de
estas limpiezas costosas, muchos de los daños son perpetuos. Como se
mencionó anteriormente Goldcorp tiene una historia de problemas ambientales
en muchas de sus minas. De no aplicarse requerimientos comprensivos de
33
Asuntos de recuperación y costos aproximados para la recuperación de la mina marlin
- UUSC - COPAE-
recuperación, la mina Marlin puede llegar a convertirse en un desastre ambiental
significativo. Sería
el mejor interés de Goldcorp mejorar su reputación
ambiental ante gobiernos y ciudadanos y llevar a cabo una recuperación
ejemplar en la mina Marlin.

RECLAMATION COST ESTIMATION SUMMARY SHEET FOOTNOTES
1. Federal construction contracts require Davis-Bacon wage rates for contracts over $2,000. Wage rate estimates may include base pay, payroll loading, overhead
and profit. To avoid double counting of any of the identified administrative costs the operator must itemize the components of their labor cost estimates or provide
BLM with a signed statement, under penalty of USC 1001, that identifies what specific administrative costs are included in the quoted hourly rate.
2. The reclamation cost estimate must include the estimated plugging cost of at least one drill hole for each active drill rig in the project area. Where the submitted
Notice or approved Plan of Operations calls for drill holes to be plugged, but doesn’t specifically require the drill holes be plugged before the drill rig has been moved
from the drill pad, the reclamation cost estimate must include the plugging cost for those drill holes. For all drill holes and wells scheduled to be left open, the
estimated plugging cost must be included in the reclamation cost estimate. Where the approved Plan of Operations proposes immediate mining through an area
where the drilling is to occur, and the cost of the post-mining reclamation is included in the reclamation cost estimate, the cost estimate does not need to include the
plugging costs for those drill holes.
3. Miscellaneous items should be itemized on accompanying worksheets.
4. Fluid management should be calculated only when mineral processing activities are involved. Fluid management represents the costs of maintaining proper fluid
management to prevent overflow of solution ponds through premature cessation or abandonment of operations. Calculate a minimum six month direct cost
estimate which includes power, supplies, equipment, labor and maintenance.
5. Handling of hazardous materials includes the cost of decontaminating, neutralizing, disposing, treating and/or isolating all hazardous materials used, produced,
or stored on the site.
6. Any mitigation measures required in the Plan of Operations must be included in the reclamation cost estimate. Mitigation may include measures to avoid,
minimize, rectify and reduce or eliminate the impact, or compensate for the impact.
7. Engineering, design and construction (ED&C) plans are often necessary to provide details on the reclamation needed to contract for the required work. To
estimate the cost to develop an ED&C plan use 4-8% of the O&M cost. Calculate the ED&C cost as a percentage of the O&M cost as follows: up to and including
$1 million, use 8%; over $1 million to $25 million, use 6%; and over $25 million, use 4%. Inclusion of a line item for the development of an ED&C plan may not be
necessary for small operations, such as notice-level exploration. With small, uncomplicated reclamation efforts contracting may be able to proceed without
developing an ED&C plan. [ED&C is automatically eliminated if "Notice" is selected on the Property Information Sheet]
8. A contingency cost is included in the reclamation cost estimation to cover unforeseen cost elements. Calculate the contingency cost as a percentage of the
O&M cost as follows: up to and including $500,000, use 10%; over $500,000 to $5 million, use 8%; over $5 million to $50 million, use 6%; and greater than $50
million, use 4%. As with the ED&C cost, inclusion of a contingency cost may not be necessary for small operations, such as notice-level exploration.
9. Insurance premiums are calculated at 1.5% of the total labor costs. Enter the premium amount if liability insurance is not included in the itemized unit costs.
10. Federal construction contracts exceeding $100,000 require both a performance and a payment bond (Miller Act, 40 USC 270et seq.). Each bond premium is
figured at 1.5% of the O&M cost. Enter the sum of both premium costs on this line.
11. For Federal construction contracts, use 10% of estimated O&M cost for the contractor’s profit.
12. To estimate the contract administration cost, use 6 to 10% of the operational and maintenance (O&M) cost. Calculate the contract administration cost as a
percentage of the O&M cost as follows: up to and including $1 million, use 10%; over $1 million to $25 million, use 8%; and greater than $25 million use 6%.
13. BLM’s indirect cost rate is 21% of BLM’s contract administration costs.
