Comstock Options Rawhide Cobalt-Silver Project in Gowganda Area, Ontario

Vancouver, BC – April 5, 2018 – Comstock Metals Ltd. (TSX-V: CSL) (“Comstock” or the “Company”) is pleased to announce that it has entered into an option agreement whereby it can acquire a 100% interest in five mining claims located in the Gowganda area of the historic Greater Cobalt Mining Camp of northern Ontario, comprising the Rawhide cobalt-silver property (the “Rawhide Property“).  Mines in the Greater Cobalt Mining Camp produced over 550 million ounces of silver and over 25 million pounds of cobalt in the 1900s1; the area is currently undergoing an exploration renaissance with increased market interest in cobalt metal as it is one of the most prospective areas for cobalt-silver deposits in North America.

This option of the Rawhide Property is Comstock’s first step in diversifying its mineral property portfolio, which currently includes two resource-stage Canadian gold projects, to include properties focussed on battery metals such as cobalt and lithium.

“We are looking forward to commencing work on this new opportunity in the historic Greater Cobalt Mining Camp” stated CEO David Terry. “Comstock is also finalizing its plans for a summer exploration program on its Preview Gold Project to follow up on last year’s significant results”.

The Rawhide Property consists of five mining claims comprising 42 claim units (662 ha) and is located immediately northeast of Castle Silver-Cobalt project of Canada Cobalt Works2 (Map 1).  It is road accessible and has excellent access to infrastructure. The Rawhide Property covers a number of documented historical mineral occurrences.  Reported work includes prospecting, mapping, sampling, geophysics, pitting and trenching, limited diamond drilling and excavation of a number of shafts; a summary is provided in the following table:

Table 1: Rawhide Cobalt-Silver Property Historical Mineral Occurrences

Mineral Occurrence Details*
Bloom Lake3,4
  • Adit on 5-15 cm carbonate veins with erythrite (cobalt arsenate) mineralization and several test pits
  • Geologic mapping, geochemistry, geophysics (1960s)
  • Sample of a 5 cm calcite vein in diabase 7.7% copper, 0.1% cobalt, 21 g/t silver
  • Three shafts and areas of stripping and trenching (early 1900s); erythrite reported
  • 29 calcite+/-quartz veins identified; 4,500 g/t silver assay reported from 22 vein
McRae Lake3,6
  • Shaft and several test pits on quartz-carbonate veins up to 5 cm in diabase
  • 597 m in 11 diamond drill holes (1950s-1960s); carbonate veins to 3.8 cm reported
  • Assays include 46 kg/t silver
  • Two-compartment shaft of unknown depth on system of 2.5 cm calcite veins
  • 650 m in 15 diamond drill holes (1950s-1960s)
  • Assays including 252.8 g/t silver, 1.81% cobalt, 2.85% copper and 1410 ppm nickel

*These reported historical results were used to help prioritize the optioning of the Rawhide Property, however, the reader is cautioned that the Company has not had a Qualified Person (as that term is defined in National Instrument 43-101) visit the Rawhide Property to confirm the results, or their significance, and that proximity to a discovery, past-producing mine, or mineral resource, does not indicate that mineralization will occur on the Rawhide Property, and if mineralization does occur, that it will occur in sufficient quantity or grade that would result in an economic extraction scenario. Detailed descriptions of sampling for which assays are reported were not provided in many cases in the historical reports and, therefore, they should not be considered representative.

The Rawhide Property is underlain predominantly by a north-south oriented body of Nipissing diabase (~1 km wide) which cuts Cobalt Group sediments and felsic intrusive rocks (Map 2).  Distribution of the silver-cobalt veins in the Cobalt district is controlled by the contact between the Nipissing diabase sheets and the rocks of the Cobalt Group (Gowganda Formation). The veins occur in the diabase and in the sedimentary rocks within about 200 m of their contact with the diabase. They generally dip steeply, extend horizontally as much as 1,000 m and vertically as much as 120 m, and vary up to 1.2 m in width3.

Option Agreement Details

Under the terms of the option agreement, Comstock can earn a 100% interest in the Rawhide Property by making cash and share payments to the optionors, and completing exploration expenditure commitments, over two years. Details are provided in the table below.

Timing Cash Payment Share Payment Expenditure
Receipt of regulatory approval $30,000 200,000
6 Months from Signing $30,000 200,000
12 Months from Signing $35,000 200,000 $100,000
18 Months from Signing $35,000 200,000
24 Months from Signing $45,000 200,000 $400,000
Total $175,000 1,000,000 $500,000

In addition, if the option is exercised by Comstock, the optionors will retain a 2% Net Smelter Returns royalty (NSR) on future production from the Rawhide Property, 1% of which can be purchased at any time for $1 million.  The option agreement remains subject to approval by the TSX Venture Exchange.

About Comstock Metals Ltd.

Comstock Metals Ltd. is a Canadian-focussed mineral exploration company with two 100% owned resource-stage gold projects.

  1. Preview SW Gold Project, Saskatchewan: The Company’s road accessible Preview SW gold project is located 40 km north of La Ronge, Saskatchewan and 80 km southwest of Silver Standard Resources Inc.’s Seabee gold mine. The main Preview SW deposit hosts a NI 43-101 Resource Estimate (see Comstock’s news release dated September 14, 2016) which includes Indicated resources containing 158,300 ounces of gold (2.61 million tonnes grading 1.89 g/t Au) and Inferred resources containing 270,800 ounces of gold (5.70 million tonnes grading 1.48 g/t Au), both based on a 0.50 g/t Au cut-off grade. The main Preview SW deposit is comprised of several sub-parallel northeast-trending gold-bearing quartz-sulphide mineralized structural zones, 550 m in strike length and totalling 150 m in width.  Preliminary metallurgical test work indicates total gold recovery in concentrates ranged from 90% to 93%. In addition, there are six additional known gold zones on the 853 ha property with only limited drilling. At the Preview North zone, located 2.6 km northeast of the Preview SW deposit, drill hole PR13-163 intersected: 17.98 g/t Au over 5.71 m starting at 10 m below surface, 5.96 g/t Au over 5.66 m starting at 19 m below surface and, 1.88 g/t Au over 21.26 m starting at 29 m below surface.  Based on 2017 drilling with oriented drill core true thickness is interpreted to be approximately 85% of drilled width.
  2. QV Gold Project, Yukon: The +16,000 hectare QV Property is located in the White Gold district of the Yukon Territory, approximately 70 kilometres south of Dawson City and 44 kilometres northeast of the Coffee project of Goldcorp Inc., which it acquired through an acquisition of Kaminak Gold Corporation. To date, the Company has completed 3,400 m of core drilling in 17 drill holes which formed the basis for a maiden Inferred mineral resource totalling 4.4 million tonnes grading 1.65 g/t gold containing 230,000 ounces of gold at a 0.5 g/t gold cut-off (See Comstock’s news release dated July 8, 2014). The VG deposit remains open to expansion and is proximal to other untested sub-parallel structures. The VG zone has similar geology and style of mineralization to Kinross’s Golden Saddle deposit, located 11 kilometres to the south. Additional promising targets exist on the QV Project, with potential for the discovery of significant intrusion related and/or orogenic gold mineralization. The infrastructure associated with the development of the Coffee project, including upgrading and completion of the mine access road, will benefit all projects in the district, including the QV Property.
  3. Additional Assets: Comstock also owns the early stage Old Cabin gold project in Ontario and uranium claims in the Patterson Lake area of Saskatchewan and has optioned out its Corona property in Mexico (see Comstock’s news release dated January 28, 2016).
