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 north 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).
