History

Renowned as one of the highest-grade longest producing mines in British Colombia, the three historic mines of the Bralorne Mine Complex, Bralorne, Pioneer and King produced a total of 4.2Moz at an average recovered grade of 17.7g/t. Production closed in 1971 due to subdued gold price (US$35/oz, US$220/oz in current dollar value). On average, production at the Pioneer and Bralorne produced 2,300 ounces per vertical metre mined.

Of the 63 veins identified, only 30 were mined, 29 of them to a maximum depth of only 900 metre. One vein, the 77T was mined continually to 1.9 kilometre showing the incredible depth continuity of the structure. All of the veins remain open at depth and many, including the 77T remain open along strike.

Deposit Geology

Bralorne is a phanerozoic Orogenic gold vein system. Also known as mesothermal vein deposits, Bralorne is analogous to the Motherload deposit of California, the Cariboo Deposit in BC (Barkerville Gold Mines) and the Curraghinalt deposit of Northern Ireland.

The gold-quartz veins form an approximate en echelon array. They have strike lengths of as much as 1,500 metre between bounding fault structures, and extend to at least 2,000 metre in depth, with no significant changes in grade or style of mineralization recorded. Ores consist mainly of ribboned fissure veins with septa defined by fine-grained chlorite, sericite, graphite or sulphide minerals.

Veins are dominantly composed of quartz, with minor carbonate minerals, mainly calcite and ankerite, and lesser amounts of chlorite, sericite, clay altered mariposite, talc, scheelite and native gold. Sulphides are present and, although locally abundant, make up less than 1% of total vein volume. Pyrite and arsenopyrite are the most abundant sulphides with lesser marcassite, pyrrhotite, sphalerite, stibnite, galena, chalcopyrite and rare tetrahedrite.

Excellent Metallurgical Recovery

Bralorne boasts proven mineral processing flow with a combination of gravity and float concentrate giving a historic metallurgical recovery average of 90%. Historically 65% of recovery was derived from a gravity circuit with 35% from a flotation concentrate. Talisker anticipates this recovery could be improved utilizing modern mineral processing methods.

Site Infrastructure

The Bralorne project is supported by significant infrastructure with direct highway access, grid connected electricity, permitted tailing storage facility, water treatment facilities, offices, mill building, underground workshop, mine dry, core logging, processing and storage, bunkhouse, kitchen, ambulance and mine safety, and industrial fuel storage facilities.

Access

Easily accessible by car from Vancouver, Bralorne can be reached either via Lillooet (Highway 40, 371 kilometres) or via the Hurley Pass (231 kilometres) with Highway 40 maintained by the BC Government providing year-round access.

Grid Power

The Bralorne site is connected directly to grid power with a 1500kva line from the Lajoie Hydro generation plant just 4 kilometres direct line from the site. The Lajoie dam and plant is part of the Bridge River hydroelectric complex that has capacity to generate 492 megawatts of power.

Tailings Storage Facility

The Tailings Storage Facility (TSF) is permitted under the existing mine permit. The tailings and water ponds are contained within a footprint area of approximately 4 hectares. The combined area of disturbance including TSF, dam, seepage ponds, borrow areas, and topsoil stockpile is approximately 10 ha. The volume currently available within the TSF is estimated at 126,000m3 or approximately 170,000 tonnes of tailings (average settled dry density of 1.35 tonnes/m3). The current permitted area would allow for significant increase in storage capacity.

State of the Art Water Treatment Facility

The Bralorne site has a fully permitted and operational water treatment facility. The current facility was commissioned on April 1, 2016 and consists of a modular PALL Aria microfiltration system. The system is actively used to treat mine discharge and mine water from the current dewatering program. Under Discharge Permit 14480, treated water can be discharged continuously to Cadwaller Creek at a rate of 3 million litres per day. Additional water is permitted to be discharged to the Tailings Storage Facility. Sludge from the microfiltration system is contained in geotubes, which are then transported to a storage location in the tailings facility for permanent storage.

Existing Resource to Build on

A small high-grade resource has been defined by the previous owners of the Bralorne project in the “Gap” zone between the historic mines. The table below defines the breakdown of the existing resource. Please note the table is in tons and ounces per ton. Talisker is reviewing the viability of this resource and possibilities for expansion particularly near surface.

District Scale Exploration Upside

A district scale consolidated land package of 11,700 hectares covers the entirety of the Cadwallader Break, the main conduit for gold mineralisation in the Bralorne District. Forty six small mines and vein occurrences have never been subject to modern exploration techniques. Talisker is currently compiling the wealth of historic exploration data and building a comprehensive 3D model to aid brownfields targeting in the vicinity of the Bralorne Mine Complex.
