MDD Field Trip to the Myra Falls Cu-Pb-Zn-Au
January 2005 Issue 84 MDD Field Trip to the Myra Falls Cu-Pb-Zn-Au-Ag Mine Hendrik Falck C.S. Lord Northern Geoscience Centre PO Box 1500, 4601-B, 52 Avenue, Yellowknife, NT, X1A 2R3 Dani Alldrick BC Geological Survey, 5 - 1810 Blanshard Street, Victoria, BC V8T 4J1 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 Inside this issue: al., 2005).

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.

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 (Continued on page 4) January 2005 – Gangue No. 84 3 (Continued from page 3) 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. Hendrik (Continued from page 1) 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 Fig. 2. Textures of the various sulphides: a) Gap deposit: bornite and chalcopyrite vein within altered host rock; b) Battle deposit: banded sphalerite and chalcopyrite; c) Folded pyrite (yellow bands) and silica and sphalerite (grey bands) with cross-cutting chalcopyrite veinlets; d) 43-block ore clast polymictic breccia with cobble to boulder size sulphide rafts (scale in decimeters). Modified from Chong et al. (2005). January 2005– Gangue No. 84 4 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 Fig. 3.

These “feeder zones” are also Myra Falls Mine. 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. ground. At the mine the next morning, we were met by Hardolph again who January 2005– Gangue No. 84 5 (Continued from page 5) 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. Fig. 6. A folded sequence of thinnly bedded sediments 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.

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. January 2005– Gangue No. 84 8 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. A thumbs up on the BC Liberal Government’s $25million dollar donation to Geoscience BC.

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) 9 (Continued from page 9) 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.
