Rokmaster Resources

High Grade Zinc-Lead-Silver Discovery Zones in the Kootenay Arc

This profile is part of a paid investor education campaign.*


Rokmaster Resources (TSXV:RKR | OTC PINK:RKMSF | FRA:1RR) is a Vancouver-based mineral exploration company focused on acquiring and developing early-stage precious metals and base metals projects. Its current focus is its the 100% owned Duncan Lake Zinc Project in the Kootenay Arc of southeastern British Columbia.

The Project discovery was made by Cominco, whose Canadian geological team discovered higher grade strataform zinc-lead mineralization; open on strike – down dip, on plunge – along both limbs of Duncan Anticline. Teck Resources’ mineral tenures of interest over the Duncan Lake Project discovery area expired in 2015.

Fully-permitted for drilling, the company has planned multi-stage programs aimed at proving up a NI43-101 resource.Rokmaster is following Cominco’s recommendations which included 17,150 meters of additional drilling.

To that end, Rokmaster has the privilege of adding to its team two former Teck-Cominco experts previously associated with the Duncan Lake Project: Ted Muraro, P.Eng., Cominco’s former Chief Geologist who carried out a number of geological exploration programs in the area of the Duncan Lake Project culminating in the authoring of his M.Sc. thesis, and David Moore, P.Geo., Manager of Canadian Exploration at the time Cominco was drilling the Duncan Lake area and who recommended expanded drilling of the project.

Rokmaster Resources’ management team of industry veterans is experienced in fast-tracking projects from discoveries through to commercial production. President and CEO John Mirko played an instrumental role in permitting, constructing and operating the MAX Mine in Trout Lake, BC, for which he was a recipient of the “E. A. Scholtz Medal for Excellence in Mine Development” from the Association for Mineral Exploration of British Columbia in 2008, and the “Mining and Sustainability Award” from the Mining Association of British Columbia in 2009.

To take the Duncan Lake Project forward, Rokmaster has assembled a team with more experience in the area than anyone.

Investment Highlights

  • 100% owned project with proven strataform zinc-lead discovery, located in British Columbia’s resource rich Kootenay Arc.
  • High grade zinc-lead intersections over a 650 m strike length, with potential for high tonnage, as well as silver and copper mineralization.
  • Mine potential with large new sedimentary hosted higher grade zinc-lead zones.
  • Drill ready with permit in hand. NI 43-101 Technical Report completed, available online.
  • Award-winning management and technical team, production experience in the region and well-seasoned in discoveries and mine development.
  • Key infrastructure in place including Teck’s Trail Smelter, located in the Slocan mining district with favorable jurisdiction.

Key Project: The Duncan Lake Zinc Project

The Duncan Lake Project is located at the north end of the Kootenay Arc. The area is responsible for more than 50 million tons of zinc-lead-silver ores mined from ten past-producing deposits including Grandview-Metaline, Reeves MacDonald, Jersey-Emerald, HB and Bluebell Mines, and Teck Resources’ currently producing Pend Oreille mine. Mineral exploration in the Duncan Lake region dates back to 1890.

Between 1957 – 1961 Teck conducted drilling, underground development and metallurgical studies on its historic Duncan Mine prospect, a 275 hectare claim group 2.5km south of Rokmaster’s discovery area. While the prospect never went into production, it does have a historically non NI 43-101 compliant underground zinc-lead resource of 3.9 million tonnes at 3.3% zinc and 3.1% lead.

Cominco later conducted four phases of exploration diamond drilling 2.5km north on what is now Rokmaster’s property. Drilling totaled 8,334 meters over 12 holes between 1989 and 1997. The drill work encountered significantly higher grade zinc-lead mineralization than what was seen on Teck’s claim group. Cominco’s exceptional (true width) drill results include:


Rokmaster now owns Cominco’s Project discovery zone, and the company is using their expert recommendations to plan drilling of the exploration target. With favourable jurisdiction, year-round access and proximity to Teck’s smelter at Trail, the Duncan Lake Project is well positioned for significant development.

Excellent regional infrastructure is in place, including:

    • Trail Smelter (150 kilometers by road)
    • Hydro 3 phase power line (15 kilometers)
    • Paved Highway (22 kilometers)
    • Railway (100 kilometers)
    • Airport (115 kilometers)

Recent Work

Rokmaster’s expanded Duncan Lake Project encompasses over 5,600 hectares of mineral claims, hosting mineralized zones with grades typically above 10% zinc and lead.

In mid-2017, Rokmaster acquired 3 additional claim blocks—two of which are located 7 kilometers on strike to the south of Duncan Lake and one claim block that adjoins the Project. Following a review of the historical data on the claims, Rokmaster’s technical team has noted several zinc-lead occurrences similar in nature to those found on the Duncan Lake claims. Occurrences of copper-bearing rocks were also discovered by previous operators 6 kilometers southeast of the central portion of the Project, including copper-bearing float assaying up to 5.9% copper, 12.3 grams silver and 107 ppm zinc.

The company also fully acquired 11 mineral claims totaling 620 hectares south of and adjacent to, its Duncan Lake Project. The new property forms part of the Company’s Duncan South Area which now covers over 12km of important southerly extensions of both limbs of the Duncan Anticline, where it comes to surface. Documented historical mineral occurrences located on the property include the No. 1, No. 2, No. 3 and VIN Zones. A persistent zone of zinc-lead mineralization up to 3m thick, 30m high and exposed for 90m along strike in an old adit is reported to average 6.36% zinc and 2.46% lead across 1.13m width over the entire length of the zone.

Prospecting for silver and gold enriched silicified zones in the hanging wall of the zinc-lead zone commenced in autumn along a 5km portion of the trend north of the No. 1 Zone. Prospectors also discovered historical adits to underground workings, revealing high grade zinc samples from the property that was not previously noted in historical records.

Camp construction, drill preparation, and property maintenance are ongoing throughout the year, as the Project provides year-round access for drilling due to its low elevation, mild winter and consistent access by road.

2018 Drill Plans

Rokmaster is planning a two-phase drill program for 2018 that will extend targeted historic holes to intersect areas of thicker mineralization and will also include new drill holes testing strike to the north and south of the historic drill zone with the ultimate goal of defining a NI 43-101 compliant resource. Exploration work around the copper area will search for the source of the high-grade float and additional evidence of copper-zinc deposits.

The Duncan Lake Project has only ever been first stage drill tested, demonstrating a major find with outstanding potential. Cominco was unable to continue its drill plan due to a poor metal market and their impending takeover by Teck Resources Ltd. (today Canada’s largest diversified mining company), before they had stopped all south east BC zinc exploration.

Rokmaster’s team now has the ability to realize this opportunity. Moderate drilling is needed to outline a possible resource between 7-10MMT. Using Cominco’s exploration target of 16M metric tons at +10% zinc, an in-ground gross value at today’s zinc price of $5 billion might be quite achievable.
