The Mineral Deposits Division (MDD) of the Geological
Association of Canada has a long history of running field trips
to interesting localities. With the rise of metal prices and a
revitalization of industry activity, this tradition has also revived. This January, in conjunction with the 2005 Exploration
Roundup held by the BC and Yukon Chamber of Mines, MDD
organized an excellent excursion to the Myra Falls Cu-Pb-ZnAu-Ag Mine.
Located 90 kilometres southwest of Campbell River, polymetallic volcanic-hosted massive sulphide (VHMS) deposits
are currently being mined at the southern end of Buttle Lake in
the centre of Strathcona Provincial Park, making this an excellent example of the successful juxtaposition of diverse land
uses.
The Myra Falls Mine (Fig. 1) has been in operation since
1966 and is currently owned and operated by NVI Mining
Ltd., a subsidiary of Breakwater Resources Ltd. following
acquisition from Boliden Westmin (Canada) Ltd. in July,
2004. The operation produces approximately one million tonnes of ore per year. Three main orebody clusters, the H-W, 43
Block, and Battle-Gap are currently being mined, but several
other zones including the Lynx-Myra-Price trend have seen
production. Over 24 million tonnes have been mined in the
last 39 years with an average grade of 5.0% zinc, 1.8% copper,
2 g/t gold and 52 g/t silver (Pardy, 2004). The 2002 “PreMining Geological Inventory” estimate of global mine resources stood at a total of 40,965,872 tonnes with an average
deposit size of 3.4 million tonnes grading 6.1% Zn, 0.5% Pb,
1.8% Cu, 2.1 Au (g/t), and 49.0 Ag (g/t) (Chong et al., 2005).
In January 2004 the diluted mining reserve was estimated at
7,746,914 tonnes, grading 6.33% Zn, 0.52% Pb, 1.15% Cu, 1.2
Au (g/t), and 39.98
Ag (g/t) (Chong et

of the Wrangellia terrane (Hoy, 1991; Jones et al., 1977). Mine
stratigraphy commences with andesitic volcanics of the late
Devonian Price Formation (Pearson, 1993). These massive
flows and flow breccias are conformably overlain by the Myra
Formation, the main ore host. This 300 to 450 metre thick
formation consists of rhyolitic flows and volcaniclastic layers
interbedded with more intermediate volcanic flows and breccias. Zircon age determinations from the Myra Formation
indicate a late Devonian to early Mississippian (365-370 Ma)
age. The Thelwood Formation overlies the Myra Formation
and consists of subaqueous pyroclastic layers interbedded with
fine-grained mafic volcaniclastic turbidites. These sediments
were intruded by penecontemporaneous mafic sills.

Dear MDD Members,
While this may have already happened to you in the rest of Canada, the
first signs of spring have finally made it north to Yellowknife. For my
family, the arrival of the bald eagles that nest on our lake has the same
impact as seeing the first robin. And hey, a rain shower, we have not had
rain since late September!
Over the winter the MDD has been busy. The launch of the Ore Mineral
Atlas has been a great success. Sales at the PDAC were brisk and the book
is a bargain in my opinion. Have a look at it when you get to the AGM in
Halifax. MDD has also organized its first field trip, independent of the
AGM, after a hiatus of many years. The trip to the polymetallic volcanogenic massive sulphide mine at Myra Falls, BC was a great excursion and
efforts are underway to organize a trip to Eskay and Galore Creek that is
anticipated to happen in the early Fall.
Another front that the MDD has been working on is the main topic that
I want to address in this letter. For the past several years, repeated comments have been made by MDD members that we should seek common
ground with “like-minded” organizations in an effort to reduce duplication
and fragmentation, while improving synergistic efforts.
One such opportunity, the possibility of participating in a research journal, has arisen. Currently, the Geological Society of the Canadian Institute
for Mining and Metallurgy (CIM Geological Society) maintains the journal “Exploration and Mining Geology” (EMG). MDD members have been
offered subscriptions to this journal at a special rate, which is higher than
the CIM member rate, but lower than the non-member rate. However, in
spite of good efforts to advertise the offer, few MDD members have taken
advantage of it. One possible explanation is that MDD members interested
in the journal are already receiving it through their CIM membership. In
order to encourage new subscriptions, the CIM has now decided to offer
EMG at the CIM member rate (currently $35 per year) to all GAC members and those of several other geological societies.
In addition, to widen the distribution of the journal, arrangements have
been made by the CIM Geol. Soc. to have an electronic version of the
journal available on the web through http://www.geoscienceworld.org/.
The electronic version is available to all EMG subscribers.
While the means of getting the journal out to people are improving, the
nature of the material to be published is also being examined. Initially, the
journal was conceived to be a venue to publish papers by mining and exploration geologists working on the latest deposits and properties, and
highlighting the descriptions of these occurrences. New advances and
challenges in applying exploration techniques were also considered as the
type of topic that would be contained within a volume.
Almost all of the people with whom I have had discussions about the
journal, concur that such types of papers would be of great interest; however, finding, encouraging and supporting contributing authors of such
papers has been challenging and problematic. Companies are commonly
indifferent to, or even actively opposed to having their geologists publishing papers on topics that might give the competition the edge on the next

great strike. Even in cases where there is no real competition, they believe that it is difficult to justify to the shareholders that
their geologists become involved in such endeavours. Of greater immediate concern are the corporate bottom line and restoring and adding geological resources to the company inventory. Fortunately, there are still people out there who do take their
research home and contribute excellent papers on these topics but it has been difficult to sustain the journal on the basis of
these exceptional individuals.
The MDD is uniquely qualified to address some of the issues that the journal is currently facing. We have a membership of
approximately 700 individuals, many of whom are actively involved in research on ore deposits and the methods of finding
them. While the MDD includes many industry professionals, the majority of members are in the ranks of the government and
academia. Both of these groups are required to produce high quality written material as a matter of course and publishing is
often a requirement of their positions. In the academic community, upper level graduate students are considered to be one of
the largest “untapped resources” available to the journal. Identifying student authors and topics is best done by the professors
who have supported the research.
This brings us to the question of the approach that MDD should take and for that I am looking for guidance from you, the
MDD members. There are many options possible and discussions are at an early stage with no set agendas. Options include:
A) Do nothing. MDD is very successful at identifying topics of interest to its members, and assembling authors and publishing books on these. Involvement in a journal could undercut some of this activity and we might end up competing with
ourselves.
B) Establish our own journal and take on the massive task of growing it into a respected publication, while maintaining it
financially until it is self-sustaining. This would be a tremendous amount of work to sustain without some level of partnership with other groups and likely beyond our financial means.
C) Partner with CIM Geol. Soc. at a mutually agreeable level to assume some of the responsibility and benefit from maintaining and growing the existing journal. This option could entail anything from increased advertising and volunteer efforts to help the journal with a financial contribution and take on formal partner status in the publication.
I have some thoughts on which approach to take, as do the Executive and Council for the MDD, but all of us would like to get input
from you, the members of the MDD. This is an important issue that could have long term implications for the MDD. We would like to
hear your opinions. This is a topic for the agenda at the MDD Annual General Meeting in Halifax but I would also like to hear from the
members who are unable to attend the meeting. I ask you to send me an email with your thoughts at [email protected]
I thank you in advance for your input. Participation by its members has been one of the greatest strengths of the MDD and I look forward to your comments.

The host rock sequence has been metamorphosed
to lower greenschist facies during early Mesozoic
burial metamorphism with localized contact effects
due to the emplacement of Early Jurassic quartz
diorite intrusions (Juras, 1987). This metamorphism
is responsible for the favourable increase in sulphide
grain size.
Five separate deformation phases have been defined (Jones, 2001). Collision of Wrangellia with

ancient North America produced a large-scale upright
anticline. This structure was modified by D2 ductile
shears and by three subsequent generations of faulting. The resulting geometry of the orebodies is complex; suspected thrust duplication of sequences has
been followed by fault dissection into numerous
blocks.
VHMS mineralization is largely confined to three
rhyolite horizons within the Myra Falls Formation.
The H-W horizon and the Lynx-Myra-Price (L-M-P)
horizon are the main host rocks for the known orebodies; the third horizon remains largely unexplored
but has excellent exploration potential for hosting
resources.
Footwall fluid conduits are poorly preserved at
Myra Falls but several examples of synvolcanic
faults and fracture zones have been identified. The
locations of the conduits are based on changes in the
footwall elevation, variations in the Myra Falls Formation thickness, and marked changes in the volcanic

indicated by an abundance of mafic dykes as well as
a copper-iron enrichment of the stringer sulphide
zones (Chong et al., 2005). Ore is constrained to northwest trending corridors now delineated over a six kilometre strikelength, but the ultimate depth and lateral extent of this extensive hydrothermal system has not been determined.
Alteration mineralogy is dominated by sericite and silica-flooding with significant amounts of chlorite, albite and carbonate. Near the deposits, footwall rocks are pervasively sericite-chlorite-silica altered. Polymetallic orebodies consist of massive to semi-massive and stringer sulphides. Several sulphide assemblages have been identified including sphalerite, sphaleritechalcopyrite-pyrite and pyrite-chalcopyrite. Figure 2 illustrates a few
examples of the sulphide textures within the orebodies.
Portions of each deposit, referred to as the Upper Lenses, have an
atypical assemblage of sphalerite-galena-barite-chalcopyritetennantite+bornite+electrum. The base metal concentration of the
Upper Lenses is not as high, but the addition of tennantite and electrum elevate precious metal contents, with grades ranging as high as
25 – 85 g/t Au.
The fieldtrip started at the Westin Hotel in Vancouver where the
party of nine boarded the tour bus and received a 45-page tour guidebook produced by mine geologist Albert Chong. We arrived at the
Horseshoe Bay ferry terminal with time to spare; after a calm ferry
ride to Nanaimo it was on to Campbell River with an overview of the
geology along the way by Dani Alldrick. A crucial stop was made to
pick up refreshments, and off we went down the highway again, arriving at Strathcona Park Lodge, where staff had been rousted out of a
mid-winter slumber to host our visit.
An excellent supper was followed by introduction to Hardolph Wasteney, the Myra Falls Operations mine geologist, who would be our
tour guide. Hardolph brought in a large collection of samples, including a collection of large samples, plus several huge slabs, allowing us
to have a first look at the mine rocks, ore and alteration (Fig. 3). A
short talk on the local geology was followed by an extended question
and answer session. Eventually even the most persistent geologists
were satisfied and we called it a night, with the hand sample grading 8 Fig. 4. Field trip participants preparing to go underounces per ton gold still accounted for.

At the mine the next morning, we were met by Hardolph again who

provided an introduction to the local geology while waiting for the cage
(Fig. 4). On the 1800 level we were met by a vehicle and driver, essential for getting a large group around this extensive mine in a timely
fashion.
At the Gnu Zone we were able to see a standard production heading
with banded massive sulphides interbedded with chert layers (Figs. 5
and 6). Bedding was tightly folded with local remobilization of sulphide minerals. The second stop was at South Trough Lens where a
mafic dyke cuts though a zone of deformed chalcopyrite-rich ore. Stop
3 was along the 173 Ramp, 20 metres below the main Battle Zone
where the footwall stockwork was well exposed as abundant thin pyrite
veinlets cutting chlorite-carbonate altered andesite flows.
At Stop 4 the Battle Zone consisted of a 10 meter-thick lens of massive sulphide. Stop 5 displayed two different sections through Upper
Lens mineralisation located just above the Gopher Zone. In the centre
of the area, a massive QFP intrusion shows faint evidence of flow laminations. Along strike to the east from the massive intrusion, the QFP is
brecciated with sulphide minerals infilling the fractures (Fig. 7). Silicification is more significant in the western section where silica flooding
has extensively altered the breccia. Stockwork is associated with disseminated sulphides including pyrite, sphalerite and tennantite.
At Stop 6, a high grade portion of Upper Lens ore, the rock was cut
by numerous quartz veins containing abundant tennantite and electrum
(Fig. 8). In local pods up to 100 m3, grades can range up to 85 g/t Au
equivalent. Barite is a major component of the wallrock and there are
also abundant patches of sphalerite and galena. Copper tends to be less
economically significant in these zones, but there are local patches of
bornite.

with thin layers of sulphides.
From this impressive final stop, we loaded back onto the truck and drove
back towards the shaft and on to the bus for the trip back to the continent.
After another fine meal at Strathcona Park Lodge, our tour bus returned us to
the Westin Hotel in Vancouver by 7:00 pm.
Thanks to all the people who made this such an interesting journey. The
Mineral Deposits Division is actively looking for new destinations for field-

B.C. & Yukon Chamber
of Mines Hosts
Another
Successful Roundup
By Julie Domvile
The 22nd annual Mineral Exploration
Roundup was held from January 24th
to 27th in Vancouver, BC. Hosted by
the B.C. & Yukon Chamber of
Mines, Roundup is the second largest mineral exploration conference
in the world. This year’s theme
“Discovering Our Future” brought
together an impressive international
gathering of industry leaders, explorationists, prospectors, investment
advisors, suppliers and students. Prospectors Tent at the Mineral Exploration Roundup 2005
Held at the Westin Bayshore Resort
and Marina, with its stunning views of Coal Harbour, North Shore Mountains and city skyline, the conference was a tremendous success.
Formerly known as the Cordilleran Roundup, the conference underwent a name change in 2004 to better reflect its evolution from a regional meeting of colleagues to an international conference. The attendance this year by 5200 participants from 29 countries is indicative of its truly international nature.
The four day program, officially opened by Michael Gray, (past) President, B.C. & Yukon Chamber of
Mines, Chief Ian Campbell, Squamish First Nation and the Hon. Richard Neufeld, B.C. Ministry of Energy and Mines, was divided into thematic sessions. Topics ranged from “Evolving Relationships Between First Nations and the Mineral Exploration Sector” to “Canada-The Future is Diverse.” Distinguished keynote speakers shared their substantive knowledge and insights at each of the top quality
technical sessions. Standing room only in all sessions indicated that the topics were well chosen and
keenly appreciated.
The mining sector in B.C. is experiencing tremendous growth as attested by the record attendance and
upbeat atmosphere of Roundup 2005. Investment in mineral exploration in the province topped $130
million in 2004, four times the amount spent in 2001. Premier Gordon Campbell, who attended the
Awards Dinner, chose that opportunity to announce, to a most receptive and appreciative audience, a
$25 million grant to the B.C. and Yukon Chamber of Mines for a new B.C. Centre for Geoscience. The
proposed grant reflects the commitments in the Province’s new BC Mining Plan, released the week
prior to the conference, to work with industry to improve and expand access to geoscience as a critical
step in encouraging new investment and new mineral exploration.
The Awards Dinner was also an opportunity for the Chamber to reward those who make outstanding
contributions to the mineral exploration and mining sector. This year Patrick McAndless won the H.H.
“Spud” Huestis Award; the E.A. Scholz Award went to David Thompson and Michael Lipkewich; the
Murray Pezim Award went to Ian Telfer; David Comba won the Gold Pan Award; and The Frank
Woodside Past Presidents Award recognized the efforts of John Newell, Thomas Spilsbury, and
Linda Thorstad. A new award, Hugo Dummett Diamond Award was unveiled.

Prior to the onset of the actual conference, four very successful and well attended short courses were
held. The one and two day courses covered a diverse range of topics: Uranium: Origin and Exploration
Techniques; Geophysics 101: Mag, IP and EM-Simple Tools for Success; Kimberlite, the Upper Mantle
& Diamonds; and Copper Deposits: Genesis and Giants. Approximately 559 people partook in the
courses.
This year, due to exhibitor space demands, the Core Shack and Prospectors’ Tent were moved outside
into the Core Tent, creating a much needed 3000 sq ft. The Core Shack feature, introduced at the inaugural Roundup in 1984, is believed to be the first time such a display was ever presented at a major
geological conference anywhere in North America, and possibly the world.
While Roundup has undergone many changes over the years, as imposed by the vagaries of the industry, one aspect has never lost its luster. Held as it is in the freshness of a new year, delegates at the
conference have always made the most of the social events. The conference is kicked off with the traditional Ice Breaker event which provides a wonderful, convivial opportunity to mix and mingle with friends
not recently seen and to make initial contacts with new associates. The 19th Annual Hockey Challenge
and Annual Curling Bonspiel, held in the evenings, were boisterous and well attended.
Through a joint collaboration between the Chamber and the Mineral Resources Education Program, on
the second day the busy conference floors were brightened by nearly 100 elementary students clad in
red “Roundup Rockhound” shirts and yellow hard hats. The enthusiastic 8, 9 and 10 year olds had been
studying mining and mineral resources since September and had compiled two displays boasting drawings, research projects, and 3D models for the conference. These special delegates were immersed in
a full day learning experience which included panning for gold, “stump the geologist”, and learning first
hand about the careers of exploration geologists.
The following day, the same
program brought a group of
20 secondary school students to the conference.
Post-secondary students
who were studying geoscience related programs
acted as mentors and
guides.

January 2005 – Gangue No. 84
Events such as Roundup
depend a great deal upon
the efforts of volunteers. The
Chamber is extremely fortunate to have had the services of 114 student volunteers from local universities
and technical institutes
(UBC, SFU, BCIT, and
UVIC). Randy Turner, as
conference chair, led the talented committee of 38 volunteers who contributed
countless hours of time and
energy to make Mineral Ex(Continued on page 10)

ploration Roundup 2005 a success.
"Roundup 2005 conference was the
most successful yet and an incredible
achievement for the volunteers who
made it happen. Not only did a
record 5200 delegates attend but it was
the place to be for politicians
and CEOs alike. But most importantly,
the technical program was once
again superb, making Roundup the explorationists’ conference of choice."
David Caulfield, President, B.C. and
Yukon Chamber of Mines
The B.C. and Yukon Chamber of Mines
would like to take this opportunity to extend our thanks to the sponsors, speakers, delegates, exhibitors and volunteers, without whom the event would not
be the success it is. Please join us next
January at Mineral Exploration Roundup
2006 for another wonderful opportunity
to network with competitors and colleagues, meet old friends, attend technical sessions and enjoy our fabulous
West Coast scenery and hospitality. See
you there!
