Summary
Midnight Sun Mining Corp. (“MMA”) has entered into an option agreement with Logwood
Investments (Pty) Ltd. (“Logwood”) whereby it can earn up to a sixty percent (60%) interest in
the Klein Aub Group of Prospecting Licenses centrally located in the Republic of Namibia in
Southern Africa. The Klein Aub Group consists of 3 Exclusive Prospecting Licenses EPL 3663,
EPL 3501, and EPL3760 which cover an area of 99,974.90 hectares and registered in the name
of Logwood. EPL 3663 hosts the workings of the Klein Aub Copper mine which between 1966
and 1987 processed 5,128,518 tonnes of mineralized rock and recovered copper concentrates
totaling 211,293 tonnes.
Two phases of mineralisation exist in the Klein Aub Formation a
strataform type consisting of disseminated sulphides in silicified, chloritic mudstone, and a
cross – cutting type represented by fillings of brittle fractures related to the remobilisation
during Damaran deformation and metamorphic events. Surface mineralization consists of
copper oxide mineral primarily malachite azurite.
The Kline Aub formation which hosted the mineralization extends from the Kline Aub mine site
some 15.5 kilometers to the west across EPL 3501 to the northeast corner of EPL 3760. Trenching has exposed copper mineralization occurring primarily as malachite and azurite along strike
of the formation and was confirmed by check samples taken by the author. To the south similar
style mineralization was observed in trenches at farm Blaubeker suggesting that a similar mineralizing event may be present there. The exploration data supplied by Logwood is primarily
regional in nature, this is due impart to size of the EPLs. The geophysical data sets are useful in
identifying various stratagraphic and structural components and will be useful in defining areas
for ground follow-up.
Based on a thorough review of the existing data and a property visit where samples were
taken, it is the author’s professional opinion that the Kline Aub Group of EPL’s constitutes a
property of merit with the appropriate geological characteristics to potentially host economic concentrations of copper-silver mineralization.
In order to advance the property a $1,400,000.00 Can Phase One exploration program is
recommended. Phase One would consist of a thorough and detailed search of Geological arMidnight Sun Namibia

chives and of past operators and or employees of the Klein Aub mine for available data. This
would be supplemented by a full compilation of all data pertaining to EPLs 3663, 3501 and
3760. All data would be input into a suitable digital database. Concurrent with the compilation
and data entry, a program of surficial geological mapping and prospecting at a scale of 1:10,000
along the Strike of the Klein Aub Formation west of the West Shaft to the western boundaries of
EPL’s 3501 and 3760 would be conducted. Concurrent with this ground work a combination soil
geochemical and ground geophysical surveys should be undertaken to infill gaps between surface outcrops. This Phase one program should culminate with 5000 meters of diamond drilling
to first of all test the potential of the remaining mineralization of the Vliegveld zone at the Kline
Aub Mine, and secondly to test the new targets identified by the ground work. Contingent on
positive results from Phase One, a Phase Two program consisting of 10,000 meters of diamond
or Reverse Circulation drilling would be recommended. This Phase Two program would be
estimated at $2,500,000.

Introduction
This Technical report was commissioned by Midnight Sun Mining Corp. to summarize the geology, mineralization and exploration potential of the Klein Aub group of Exploration Permits
located in the Republic of Namibia in Southern Africa (Figure 1), and to recommend a suitable
exploration program to test and expand identified copper targets. The author, Mr. Warren Robb
P.Geo. of Maple Ridge B.C., was retained by the Directors of Midnight Sun to complete this
technical report which has been prepared in conformity with guidelines presented in National
Instrument 43-101 and companion documents. The information contained in this report was
taken primarily from data, reports and maps supplied by Logwood Investment (Pty) Ltd. The
author visited the Namibian Geological Survey in Windhoek to review past exploration reports
but was unable to locate the actual reports as they either did not exist or had been lost and thus
had to rely on government annual reports and some archived company reports for the majority
of the historical data. The author conducted a personal inspection of the properties between
August 24 and August 29, 2011 and was accompanied with Mr. Robert Sibthorpe, a director of
Midnight Sun, and Mr.’s. Tom and Kevin Ye of Logwood Investments (PTY) Ltd.

Property Description and Location
The Klein Aub Group consists of 3 Exclusive Prospecting Licenses (EPL’s”) which encompass an
area of 99,974.90 hectares in the Rehoboth District, Hardap Region in the Republic of Namibia
in southern Africa see figure 1.
The property is centered at approximately 24º54’ south Lati-
tude, 16º33’ East Longitude or UTM coordinates 7353638 mS 659110 mE WGS 84 Zone 33.
The three contiguous EPL’s which comprise the Klein Aub Group are registered as EPL3663 (20,000 hectares), EPL 3501 (19,974.9 hectares) and EPL 3760 (60,000 hectares)
were originally acquired by Risk Based Solutions or its principle Dr. Sindila Mwiya in 2006
and 2007 and were then transferred to Logwood Investment (Pty) Inc. in September 2009.
The EPL’s form an irregular shaped boundary whose corner locations is shown in Table 1
and is displayed in Figure 2.
Within the Republic of Namibia the government holds all mineral rights. Mineral exploration
and development is controlled by the 1992 Minerals (Prospecting and Mining) Act, which is
administered by the Ministry of Mines and Energy.
The holder of an EPL, is required to carry on within a particular period in accordance with
the work program, prospecting operation or to expend certain expenditures and shall furnish the Commissioner with the particulars of the prospecting operations, either operation
or expenditure.
The EPL is granted for a period not exceeding 3 years and may be renewed for a further
period not exceeding 2 years at a time. The EPL cannot be renewed on more than two
occasions unless the Minister deems it desirable in the interest of the development of
mineral resources of Namibia that such license be renewed in any particular case on a third
or subsequent occasion.
At present EPL’s 3663, 3670 are in there first 2 year extension, and due to expire on April
16, 2012 and August 28, 2012 respectively. A second renewal request must be submitted no
later than 3 months prior to the expiration date. Application has been made with the NaMidnight Sun Namibia

To the best of the author’s knowledge the EPL’s have not been legally surveyed To the best of the
author’s knowledge there are no royalties, back in rights, payments or any other agreements or
encumbrances associated with the Klein Aub Group of Exclusive Prospecting licenses.
EPL 3663 contains approximately 5 million tonnes of mine tailings located just east of the village of Klein Aub. The tailings could pose an environmental hazard to the population from
winds carrying particulates, or a hazard to livestock from falling into caverns that have formed
in the tailings pile.
Logwood has received approval for exploration on the properties from the Ministry of Environment of Namibia.
No additional permitting is required to conduct exploration on the
prospecting licenses at this time.

Accessibility, Climate, Local Resources,
Infrastructure and Physiography
The Klein Aub Group is situated in central Namibia approximately 180 kilometres from the
capital city of Windhoek. The morphology of the area is characterised by flat alluvial plains
that are interrupted by rugged ridges and peaks with elevations that vary from 1480 m ASL
on the plain to and 1721 m ASL on the peaks. Vegetation consists of grasses low shrub and
small trees.
Namibia is serviced by an international Airport located at Windhoek with daily flights to
Europe and South Africa. Regionally, the Trans-Caprivi Highway a paved all weather road
linking Walvis Bay to the countries of Botswana, Zambia and Zimbabwe, as well as the
Democratic Republic of Congo. The Trans-Kalahari Highway links Walvis Bay with South
Africa’s Gauteng industrial heartland via Botswana. The Klein Aub Group can be accessed
by travelling south 90 kilometres from Windhoek along the paved two lane National Highway B1 to the town of Rehoboth, then travelling west along the secondary gravel road
designated C24, 90 kilometres to the village of Klein Aub. Access within Klein Aub Group
project area is through a network of 4 x 4 trails with various access points along the C24 in
and around the village of Klein Aub.
The village of Klein Aub has a resident population of approximately 1000 and is serviced
with electrical power but has limited suppliers. The main activity in the area is ranching
with herds of cattle, goats and sheep grazing for local consumption and for export. Fuel and
equipment is readily available at the town of Rehoboth 90 kilometres to the northeast.
The climate of the area is best term semiarid with daytime temperatures that range between
35° to 45° C from October to March, the hottest months, and can drop below freezing between June and August. The average annual rainfall of the area is around 150 mm.
Winter months may be characterised by the highest frequency of these north-eastern winds.
Due to lack of data, the frequency of high-energy gusts could not be determined and local
variability is likely to occur.

The Klein Aub permit has sufficient surface rights that should an economic mineral deposit
be defined there is adequate area for potential tailings storage areas, waste disposal, heap
leach pads if required and processing facilities. Water would need to trucked to the site for
the purpose of drilling while the flooded workings of the closed Klein Aub mine could act as
a reservoir. Mining personnel could be sourced from the village of Klein Aub or from the
city of Rehoboth.
8. History
The information in the history section is taken from the Mineral Resources of Namibia by
Schneider and Seeger, (1992), in which, descriptions of the previous copper exploration
activities around Klein Aub is described.
EPL 3663
The occurrence of copper on the farm Klein Aub 350 was first recorded by Rimann (1915).
In 1027 the mineralized zone was explored by test pits and a 10 meter inclined shaft under
the direction of Dr. Hans Merensky was driven but returned disappointing results. By the
late 1950’s most of the strike of the copper bearing horizon has been located. Mr Giep
Booysen staked most of the strike length and optioned the property to Tsumeb Corporation
Ltd. The property saw intensive drilling between 1959 and 1960 by Tsumeb Corporation
Ltd., which then dropped its option on the property. The property was then purchased by
Marine Products Limited a subsidiary of Federale Volksbeleggings bpk. In 1966 the Klein
Aub property was brought into production by General Mining/Federale Volksbeleggings
who operated the mine until 1985, the mine was then operated by the Klein Aub Copper
Company a subsidiary of Metorex. The Mine operated until 1987 when it was closed due to
low grade and depressed metal market prices, a production summary is shown in table 2.
Between 1966 and 1987 the mine processed 5,128,518 tonnes and recovered Copper
concentrates totaling 211,293 tonnes see figure 3. The mine did produce silver but the
author was unable to obtain records specifying the total amount of silver produced. The
historic literature made many references to exploration drilling but the author was unable to
find any records or drill logs.

Between 1989 and 1990 the Erongo Mining and Exploration Company conducted a 63 hole
622 meter drill program over the mine tailings at Klein Aub in an attempt to determine the
grade of copper and silver still contained in the tailings and if the material could be
retreated by acid leaching. The holes were spaced at 70 meter centers over the tailings pile.
Sampling was conducted over 1.5 metre runs and analysised individually and then
composited. The composites were then compared and a computed average was calculated at
0.23% copper, 8.6 g/t silver. Erongo conducted several leaching tests on tailings material,
using diluted (5%) sulphuric acid and 2% KCN solution (Simmonds 1990). Despite a recovery of 78.3% of contained copper over a 24 hour period under agitation an exceptionally
Project 43-101
OCT 15, 2011
Page 11
________________________________________________________________________
high rate of acid consumption was recorded varying from 78 to 206 kg H 2 SO 4 (conc.) to one
tonne tailings. This was due to the high carbonate content in the material. Thus, reprocessing of the tailings was abandoned. It was noted that a KCN solution recovered 75% of
the copper and 90.5% of the silver.
In 2003 Joubert (2003) supported by the Centre for Development of Enterprise and the
Minerals Development Fund carried out a testing programme of the Klein Aub tailings with
the objective to pre-concentrate the material by gravity separation and subsequently to
leach it. The Namibian Small Miners Assistance Centre was the promoter of the project.
The tailings dump was subdivided into 8 major abutments, A to H. Sixty four auger holes
were drilled down to a depth of 2 m. A total of 128 one-metre samples were collected and
analysed for copper.

EPL 3501
Rimann (1915) noted the presence of gold on farm Auchas 347, 80 km southwest of Rehoboth. A more detailed report by De Kock (1934) described the Auchas geology as an
anastomosing quartz vein stockwork with copper mineralisation. Average gold values are
given as 0.6 g/t gold, but restricted secondary enrichment yielded results of up to 41 g/t gold
(De Kock, 1934). Söhnge (1961) reported that copper mineralisation and minor gold were
associated with narrow chloritic schist lenses, each a few metres in length, and with branching quartz veins up to 2 m wide. Subsequent exploration was undertaken by Rand Mines
(Snowdowne, 1964) and Kappa Mining (1974).
Along the Kam River near the settlement on the eastern portion of the farm Nuwedam 348,
a geochemical survey delineated two zones of sporadic malachite in conglomerate of the
Eindpaal Member which underlies the Kagas Member of the Klein Aub Formation. Erongo
Mining and Exploration Company Ltd. continued exploring for copper by checking the
geochemical anomalies by way of ten inclined wagon drill holes totalling 216 m to test the
copper-bearing zone exposed in five trenches north of the Nuwedam settlement. No borehole logs have been found to date. No significant assays were reported except for one
borehole, where 0.8 to 1.0% copper was intersected between 4.5 and 9.1 m (Worst, 1970).
Channel samples from the trenches were assayed and returned values that ranged from
trace to 0.9% copper, and in a number of trenches that contained visible mineralization
returned values of up to 2% copper.
In 1969 a barite deposit on the farm Auchas 347, some 15 km due west of the Klein Aub
Copper Mine within the EPL 3501, was investigated in considerable detail. The barite fills an
irregular fracture in Piksteel granodiorite striking east-west for some 265 m. The vein ranges in width from 1 to 6 m on surface and dips at 80° to the north. Partly covered by surficial
deposits, the barite in places exhibits distinct banding parallel to the contact and contains
granodiorite inclusions. Several apophyses of barite extend into granodioritic wall rock. The
barite vein was prospected by several shallow trenches which revealed an average width of
4.9 m and a grade of 48.5% BaSO 4 (Fig. 3.10). The continuity of the mineralisation at depth
Project 43-101
OCT 15, 2011

was tested by 49 short inclined wagon drill holes and 5 inclined diamond drill holes figure 4.
The latter intersected the mineralized body at a vertical depth of approximately 50 m.
EPL 3670
Within the EPL 3670 and in the eastern portion of the farm Blaubeker 488, there are several
outcrops of cupriferous argillite at various levels of the succession that have been drilled.
One of these is situated at a hill north of the homestead, where an interbedded zone of argillite, siltstone and fine-grained quartzite occurs near the base of the conglomerate. This
shaley unit is about 5 to 10 m thick, has a strike length of several hundred metres, and
shows considerable malachite staining in outcrop. Copper is confined to shaley quartzite
bands up to 35 cm thick and exposed in a number of trenches in the eastern and northeastern parts of the farm. Malachite and azurite mainly present along bedding planes, also occur
sporadically in cross-cutting narrow quartz veins. The northeastern showings were opened
up over a strike distance of 170 m, and channel samples from four of the trenches assayed as
follows: 0.31% copper over 1 m (2.0 g/t silver), 0.17% copper over 4.25 m (5.8 g/t silver),
1.1% copper over 2.5 m (3.6 g/t silver). The eastern occurrence was tested by four diamond
drill holes. The cupriferous zone was penetrated at depths ranging between 13.1 and 59.3 m.
The results vary between 37 ppm and 440 ppm copper, while a maximum silver content of 1
g/t is recorded (Van Wyk, 1970).
Copper occurrences outside the Naukluft Nappe Complex have been reported in literature.
Disseminated malachite, azurite and chrysocolla with grains of chalcocite in greyish-brown
quartzite of the Kagas Member are present near the contact of the Klein Aub Formation with
the Nama Group in the northwestern portion of the farm Lepel 339. The mineralisation is
confined to a north-northeast trending fault.
Copper has been reported from several localities within the upper allochthon of the Naukluft Nappe Complex. This unit comprises in ascending order the Dassie, Zebra, Pavian and
Kudu Nappes with rocks of the Damara Sequence and is underlain by the lower Rietoog
Nappe with rocks of the Nama Group. The individual thrust plates are made up of folded
shales, quartzites, conglomerates, limestones and dolomites (Geological Survey, 1992).

Since 1969 various copper occurrences have been investigated. The mineralisation in the
limestone and shale of the Dassie Nappe is thought to be syngenetic, whereas that associated with crosscutting quartz veins probably occurred during tectonism when copper was
redistributed along fractures and breccia zones (Geological Survey, 1992).

Geological Setting and Mineralization
9.1
REGIONAL GEOLOGY
The geology of the region is dominated by Neoproterozoic (1300Ma – 900Ma) basins of the
Sinclair Sequence and their equivalents which occur as relatively narrow, discontinuous,
fault-bounded troughs which trend from southern, central and eastern Namibia over 800
kilometres into the northern part of Botswana figure 5. The troughs are volcano sedimentary basins aligned along the western, north-western and northern margin of the Kalahari
Craton in areas of Koras in South Africa, Sinclair, Klein Aub, and Witvlei in Namibia and
Ghanzi, Goha and Shinamba located in Botswana (Ruxton, 1986). These basins share similar features such as low metamorphic grade and a moderate degree of deformationand are
often termed the Kalihari Copperbelt figure 6.
The plate tectonic settings of the basins has been extensively interpreted during the last 3
decades resulting in various possible tectonic settings being proposed such as a magmatic
arc (Watters,1974), an auclogen (Kröner,1977) and as a continental rift in extensional crust
regime (Porada, 1985, Borg, 1995). A continental rift is supported by the bimodal volcanism
with thoelitic affinity, thick coarse grained clastic red bed successions and extensional tectonism which can be found in all basins (Borg, 1995).
The Klein Aub Formation that form part of the Sinclair sequence is an intercratonic basin
along a zone of crustal weakness that developed between the Kalahari Craton and Congo
Craton (Borg et al, 1995). Within the Klein Aub Formation the Kagas Member which hosts
the mineralization is interpreted to be equivalent to the “Ore Shale” within the Zambain
Copper belt. The Sinclair Sequence is bordered by the Damara Orogenic Belt in the north.
Individual rift basins such as the Klein Aub basin developed from an initial rift phase of
crustal extension and bimodal volcanism through a phase of continuous block faulting,
erosion of graben structures and continental sedimentation of the red beds that was preceded by a phase of thermal subsidence with marine or lacustrine environments overstepping
the shoulders of the initial rifts (Borg et al., 1996)
Project 43-101
OCT 15, 2011
Page 18
________________________________________________________________________
The similarity shared by the basins is also evident in their metallurgy as they all share a
pattern of the abundance of stratbound copper-silver mineralization in clastic sedimentary
rocks and numerously in volcanic rocks as well as the lack of other mineral occurrences.

Doornpoort Formation comprises of continental, partly evaporitic red beds with intercalated subaerialy extruded basic volcanic rocks.
The overlying Klein Aub Formation forms a belt of continuous outcrop extending over a
strike length of about 90km from farm Lepel 339 in the west to the farm Kareeboomkolk
424 in the east. It comprised of dark grey pyritic finely laminated sandstone, siltstone and
quartzite, sub ordinate limestone and arkose (Borg, 1988b). The rocks dip at moderate
angles to the south and have been deformed into several open folds. This formation has
attracted considerable interest over the past years since the discovery of copper within the
Formation. The Formation is overlain by oxidised arkosic quartzites which are regarded as
being equivalent to the Kamtsas Formation of the Damara Sequence (Schalk, 1970). The
prominent parallel – bedding fault in the Klein Aub Formation has dragged and fractured
the rocks within the formation and controls the shape, size and grade of the mineralized
bodies at the Klein Aub mine and surrounding areas.
The northern and western part of the Kline Aub Group is underlain by basement rocks
termed Rehoboth basement inlier. It consists of rocks of the Elim Formation (Rehoboth
Sequence), the Piksteel Granodiorite and the Kobos Granite. The basement is overlain by
Mesoproterozoic rocks of the Sinclair Sequence. The Nückopf and Grauwater Formations
form the lower part of the Sequence and consist mainly of rhyolithic volcanic rocks and
subordinate conglomerate, quartzite and minor basalt (Borg, 1995; Borg and Stanistreet,
1996) The Doornpoort and Klein Aub Formations form the upper part and are composed of
continental, partly evaporitic red beds with intercalated tholeiitic basalt, which are overlain
by fine clastic sedimentary rocks and minor carbonate (Kagas and Dikdoorn Members).
The southwestern and southern portions of the Klein Aub Group (EPL 3760) belong to the
Naukluft Mountains. They are composed of three main geological units, the basement rocks
of the Mesoproterozoic Rehoboth and Sinclair Sequences, sediments of the Neoproterozoic
to Cambrian Nama Group and nappes of the Naukluft Nappe Complex. The basement is
found mainly on the western and northern side of the mountains, and consists of meta-

sedimentary and meta-volcanic rocks, gneisses and granites, varying in age between 1800
and 1000 Ma.
9.3
MINERALIZATION
Two phases of mineralisation exist in the Klein Aub Formation a stratiform type consisting
of disseminated sulphides in the silicified, chloritic mudstone, and a cross – cutting type
represented by fillings of brittle fractures related to the remobilisation during Damaran
deformation and metamorphic events. Copper mineralization is essentially confined to
green argillite and to a lesser extent to lenses of green quartzite and shaley limestone within
the Kagas Beds.
The argillite or mineralised rocks consist of interbedded calcite quartzite, interlaminated
siltstone/mudstone, silicified chloritic mudstone, thin chloritic layers and rare layers of
calcite nodules. The permeability of the sedimentary features and tectonic features are
controlling factors for the distribution of mineralization within the chalcocite bands of the
Klein Aub mine.
Copper mineralization is also hosted by both basalts predominantly of the Doornpoort
Formation and pyritic green mudstone and siltstone of the Klein Aub Formation. The basalts of the Doornpoort Formation are generally altered and copper depleted but locally hosts
small amounts of native copper and cuprite in and adjacent to amygdales and quartz veins
(Borg, 1995). In the Klein Aub Formation copper anomalies occur as laterally extensive
anomalies which follow the stratigraphic redox contact between continental red beds and
overlying pyritic sedimentary rocks.
The disseminated mineralization at the Klein Aub mine accounts for 55% of the total mineralization. The occurrence is over a strike length of 7.5km and units in the mineralized zone
is concentrated are intercalated in a stratigraphic succession of nearly 100m and range in
thickness from cm – meters. The units dip southwards at approximately 450. The remaining
45% is hosted by fractures such as breccia zones and cleavage planes.
Project 43-101
OCT 15, 2011
Page 24
________________________________________________________________________
Chalcocite is the most abundant Cu mineral in the Klein Aub mineralization and accounts
for more than 85% of the total Cu sulphides. Minor Cu minerals are bornite and chalcopyrite occurring as a narrow fringe zone that encloses the chalcocite mineralization. A list of
the economic minerals observed at the Klein Aub mine in order of decreasing abundance
are as follows: Chalcocite, Djurleite, Digenite, Hematite, Bornite, Chalcopyrite, Pyrite,
Covellite, Native Copper, Cuprite, Magnetite, Native Silver, Malachite, Galena, Wittchenite.
According to Borg, 1995, some parts of the mineralized bodies contain rich fracture hosted
chalcocite mineralization in rocks that also contain disseminated sulphide mineralisation.
Concentrations of other minerals are low and no economically significant anomalies of Pb or
Zn have been identified up to date. There exists however Pb anomalies of up 700 ppm and
traces of galena on fractures in pyrite cubes, distal to the chalcocite mineralized zone and
the enclosing, suggesting the presence of a weakly developed lead zone (Borg, 1995).
The Klein Aub fault controls the shape, size and grade of the mineralization at the Klein Aub
mine. The mineral and metal zonation pattern of the mineralized zones is related systematically to the fault in the shape of concentric lobes with their source close to the deeper part of
the fault. The zonation pattern is elongated along the bedding of the northerly rising green
sedimentary rocks. The zonation pattern starts with a zone of native copper and grades
outwards and upwards into the chalcocite zone (main mineralization) which is enclosed by
the bornite and then chalcopyrite fringe zones. The fringe zone grades into a pyrite zone
bearing galena and finally into unmineralised rocks containing diagenetic pyrite, which is
the unaffected host rock.
EPL 3501
In the eastern portion of the farm Nuwedam 348, copper mineralisation occurs in conglomerate of the Eindpaal Member which underlies the Kagas Member of the Klein Aub
Formation. The rocks of the Kagas Member host the stratabound copper-silver mineralisation which was mined at Klein Aub.
Project 43-101
OCT 15, 2011
Page 25
________________________________________________________________________
The Klein Aub Fault which controls the shape, size and grade of the copper mineralization at
the Klein Aub Mine , seems to extend into farm Nuwedam 348, where the above mentioned
copper occurrence has been explored.
Barite
The barite deposit on the farm Auchas 347 is accessed by a 10 km long road branching off
from the district road C24. The last 2 km, which cross a hill, are in poor condition. The
barite vein was investigated by trenches and drill holes to a vertical depth of approximately
50 m (Plate 5.2). The barite vein fills an irregular fracture in Piksteel granodiorites striking
east-west for some 265 m.
In the past, some exploration activities were conducted on the gold-copper quartz vein
stockwork on farm Auchas 347, which is probably associated with the Piksteel granodiorite.
However, more detailed information is needed in order to evaluate the mineral potential.
EPL 3760
Lepel 339
The area of farm Lepel 339, where copper was found in quartzite of the Kagas Member of
the Klein Aub Formation, has a potential for a stratabound and structurally controlled copper –silver mineralisation of the Klein Aub type. The mineralisation occurs along the strike
of the Klein Aub Formation.
Blaubeker 488
Copper-silver mineralisation, occurs in rocks of the Blaubeker Formation of the Damara
Sequence in the eastern part of farm Blaubeker 488. Mineralization consists of malachite
and minor azurite mineralisation and is exposed on a steep river slope and in four trenches
on an adjacent hill crest to the east. The mineralisation is associated with grey-green shale
beds and shaley quartzite up to 30 cm thick marking a reducing environment. Up to eight
shale beds are intercalating thicker quartzite layers. The series, which steeply dips to the
northwest, is overlain by conglomerate and underlain by barren red shale. The mineralised
series is exposed over a strike length of 200 m and a width of 50 m.

Bloedrivier 491
Due to the sparse available information on the mineralised quartz vein on farm Bloedrivier
491 an assessment of its potential is impossible.
Spitskop Suidwes 500 and Kambes 498
On the farms Spitskop Suidwes 500 and Kambes 498, copper indications in lenses of finegrained limestone and locally in shale of the Dassie Nappe have been traced over a distance
of 5 km. Mineralization consists of malachite occurring on bedding planes of the limestone.
The limestone is overlain and underlain by barren red shale marking an oxidising environment. The striking feature of the copper showings is their extension over a distance of 5 km.
They seem to be associated with the same stratigraphic horizon, a shale layer with limestone
lenses. Locally, disseminated copper sulphides are occurring.
Tsabisis 340
Quartz veins have been identified as occurring on farm Tsabisis 340, which are mineralised
with copper sulphides and malachite. They very likely are of a post-deformational origin.
Garies Wes 492
The copper mineralisation occurring as Malachite is reported as occurring on farm Garies
Wes 492. The mineralization occurs in cherty layers at the base of a black limestone. It may
belong to the stratabound type.

10. Deposit Types
The type of deposit being sought for on the Kline Aub Group is a Stratabound copper-silver
deposit. The following description is taken from an abstract for the symposium on
Sediment Hosted Strataform Copper deposits by Borg and Maiden.
The basins have formed in an extensional tectonic environment, with intensive block
faulting. A lower volcanic suite is overlain by a succession of continental red-beds. Above
these beds lie grey and green, fine clastic sediments and carbonates deposited in a shallow
marine environment. The whole succession is affected by metamorphism in the lower
greenschist facies and is slightly deformed by tectonism of Damaran age. In the volcanic
suite, copper mineralization occurs in basaltic lavas that are strongly altered locally, and
gold mineralization is hosted by felsic porphyries. Stratabound copper deposits in the fine
clastic sediments consist of Cu-Ag-Au-(Pb)-(Zn)-Mo-Co, with chalcocite, bornite and
chalcopyrite as the principal economic minerals. Exploration to date has shown the
existence of five mineralized districts, with mineralized zones of between 1 and 20 million
tonnes. Although the mineralization shows a stratabound character, it is not limited to a
single horizon or host-rock. Copper mineralization occurs in pyritic slate, metasiltstone,
pyritic sandstone, calcareous slate and detrital and algal limestone. Fluids are considered to
have moved upward through the succession; they leached metals out of the volcanic rocks
and precipitated them in favorable host-rocks. Basement faults, forming horst and graben
structures, had a channeling effect on the moving fluids and determined the localization of
the mineralized bodies.
11. Exploration
Exploration programs conducted by Logwood investments have consisted of desk top
studies consisting primarily of obtaining and compiling historical data and reports and
summary’s from the Geological Survey of Namibia (“GSN”). The company purchased
geophysical and radiometric data covering the three EPL’s. There has been limited to no

12. Sample Preparation, Analyses and Security
The sampling method employed by the author was to obtain type samples of the mineralization encountered generally the author would take grab samples from dumps of the
trenches of from the bottom of trenches. The samples were placed in a 3mil poly plastic
bag and labeled with a felt marker. The samples then remained under the supervision of
the author until his arrival in Vancouver where the samples were then couriered by
Federal Express to TSL Laboratories (“TSL”) in Saskatoon Saskatchewan. TSL is an
accredited lab which conforms with requirements of CAN−P−1579, CAN−P−4E
(ISO/IEC 17025:2005)).
Upon receipt at the lab the procedure was to crush the entire sample to 70% passing 10 mesh
(1.70 mm), then riffle split and pulverize approximately so 95% passing 150 mesh (106 μm). For
Ag, Cu, Pb, Zn a 0.5 gram sample was dissolved in a four acid digest consisting of HNO3( nitric
acid)-HF(Hydrofluoric)-HCLO4)(Perchloric)-HCl( hydrochloric) and then analysed by absorption. AAS method is absorption analysis (as opposed to emission analysis). The elements in
solution are vaporized into an acetylene flame. The atoms of the element in the flame absorb
light. The analysis is performed by the measurement of the amount of this light that is absorbed
by the sample. The monochromatic light source used is selected to match an absorption line of
the element of interest. The monochromatic light source used produces a wavelength of light
that precisely matches the absorption line of the element of interest. AAS is capable of achieving
ppm values for most elements. AAS analysis can only accurately be done one element at a time.
For gold analysis the preparation was the same as for the base metal elements but a 1 AT (29.16
grams) was combined with a flux mixture of litharge, soda, borax, silica, fluorspar with fur-
ther oxidants or reductants added as required. The relative concentrations of the fluxing
materials are adjusted to suit the type of sample being analyzed. Crucibles are placed into
trays of 24 and ~120 grams of flux is added. Twenty samples, three repeats and a standard
are weighed into the crucibles, then placed into a tumbler and mixed for 10 minutes. When
mixed, the samples are removed, inquarted and fused. The resultant lead button is then
cupelled. After cupellation the subsequent Doré bead is flattened, placed in a porcelain cup
and parted with a dilute nitric acid solution. The gold obtained is decanted with de-ionized
water, dried, annealed, and weighed on a microbalance.

The author has relied on the Quality Assurance procedures employed by TSL Labs, three
standards were analysed along with the submitted samples and values returned were acceptable to the lab.
In the author’s professional opinion the sample preparation, security and analytical procedures employed by the author and TSL Laboratories were adequate given the purpose of the
check samples and the stage of exploration the property is currently at.
13. Data Verification
During the property visit conducted by the author, all the permits were visited and assessed
for access by roads and trails. The author toured the old Kline Aub Mine workings viewing
the Maria shaft location, west shaft and approximate location of the Van Zyl shaft, the
tailings impoundment area for both the Maria shaft and the near the Van Zyl shaft were
observed.
The author also viewed and verified trenches on EPL 3501, 3663, 3760. In
Windhoek, Logwood operates a modern office where a main data digital base of all exploration data is maintained. All maps and documentation are also stored here. No independent
data verification was undertaken on samples collected by previous operators or by Logwood.
During the site visit the author traveled to three documented mineral occurrences, the author attempted to access the barite occurrence on 3501 but was unable to access any of the
mineral showings in the north of EPL 3501 due to being unable to ford the river. Additionally the author was unable to visit showings on the eastern and western portions of EPL
3760 due to time constraints. The author did collect 6 grab samples of trench material
taken from trenches at Nuwedam 1, 2 Blaubeker 1, 2 and Klein Aub South mineral occurrences. Rock descriptions and assay data are summarized in table 6 below:

16. Mineral Resource and Mineral Reserve
Estimates
At present no mineral resource or reserves exist for any of the three permit areas
17. Other Relevant Data and Information
At present there is no other relevant data or information for any of the three permit areas
18. Interpretation and Conclusions
The Klein Aub Group of Exclusive Prospecting Licenses is strategically located in central Namibia with good road access and electrical power. The property hosts the past producing Kline Aub
Copper Mine which produced 211,293 tonnes of copper concentrate from 5,128,518 tonnes of
mineralized rock. The Kline Aub formation which hosted the mineralization at the mine extends
from the Kline Aub mine site some 12.5 kilometers to the west across EPL 3501 to the northeast
corner of EPL 3760. Trenching has exposed copper mineralization occurring primarily as malachite an azurite along strike of the formation and was confirmed by check samples taken by the
author. To the south similar style mineralization was observed in trenches at farm Blaubeker
suggesting that a similar mineralizing event may be present there. The exploration data supplied by Logwood is primarily regional in nature, this is due impart to size of the EPLs. The
geophysical data sets are useful in identifying various stratigraphic and structural components
and will be useful in defining areas for ground follow-up. Risks associated with regional geophysical data are that it measures the relative intensity of the physical properties of the
underlying geology, and may result in outlining a suitable geological trend to follow up, but is no
assurance that economic mineralization is present along the trend. The bulk of the information
reported on in this report has relied on historical data, or archived data which at the time of this
report was often incomplete or lost and thus could affect the prospectivity of the EPL’s. A further and more comprehensive search for historical data may for instance show that the grade of
the remaining mineralization at the Klein Aub Mine may be of an uneconomic concentration, or
that previous explorers had tested areas thought to be prospective but had shown to be uneconomic or devoid of mineralization.

18.1
Conclusions
Based on a thorough review of the existing data and a property visit where samples were
taken, it is the author’s professional opinion that the Kline Aub Group of EPL’s constitutes a
property of merit with the appropriate geological characteristics to potentially host economic concentrations of copper-silver mineralization.
19. Recommendations
In order to advance the property a $1,400,000.00 Can Phase One exploration program is
recommended. . Phase One would consist of a thorough and detailed search of Geological
archives and of past operators and or employees of the Klein Aub mine for available data. This
would be supplemented by a full compilation of all data pertaining to EPLs 3663, 3501 and 3760
including if possible purchasing any airborne EM data. All data would be input into a suitable
digital database. Concurrent with the compilation and data entry, a program of surficial geological mapping and prospecting at a scale of 1:10,000 along the Strike of the Klein Aub Formation
west of the West Shaft to the western boundaries of EPL’s 3501 and 3760 would be conducted.
Concurrent with this ground work a combination soil geochemical and ground geophysical
survey should be undertaken to infill gaps between surface outcrops. This Phase one program
should culminate with 5000 meters of diamond drilling to first of all test the potential of the
remaining mineralization of the Vliegveld zone at the Kline Aub Mine, and secondly to test the
new targets identified by the ground work. Contingent on positive results from Phase One, a
Phase Two program consisting of 10,000 meters of diamond or Reverse Circulation drilling
would be recommended. This Phase two program would be estimated at $2,500,000.
