Comstock Metals Ltd. Advances Preview SW Gold Project Drilling 23.6 m Averaging 3.60 g/t Gold
Vancouver, Jan 31, 2019 - Comstock Metals Ltd. (TSX-V: CSL) ("Comstock" or the "Company") is pleased to report the results from the winter diamond drilling program at its 100% owned Preview SW gold project, located 40 km northeast of La Ronge, Saskatchewan. These results are from 5 NQ diameter drill holes, totalling 810 metres, completed at the Preview North zone ("Preview North"). -
- 23.6 m averaging 3.60 g/t gold in PR18-187 starting at 50.40 m down hole and including 2.10 m averaging 13.85 g/t gold starting at 64.40 m down hole
- 8.00 m averaging 7.47 g/t gold in PR18-187 starting at 31.00 m down hole and including 0.75 m averaging 74.6 g/t gold starting at 33.00 m down hole
- 5.20 m averaging 5.30 g/t gold in PR18-183 starting at 113.80 m down hole and including 3.30 m averaging 8.04 g/t gold starting at 115.70 m down hole
- 21.50 m averaging 2.87 g/t gold in PR18-185 starting at 23.00 m down hole and including 3.25 m averaging 10.35 g/t gold starting at 36.75 m down hole

"We are very pleased with the results from our winter drilling program at Preview North. The discovery of multiple occurrences of visible gold in 4 of the 5 holes drilled with corresponding high-grade intercepts continues to validate the Company's Preview North zone exploration strategy", commented Comstock's Interim CEO Steven H. Goldman.
The Preview North zone is located approximately 2.6 km northeast of the Preview SW deposit which hosts 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)1, both based on a 0.50 g/t Au cut-off grade (see Comstock's news release dated September 14, 2016).
The 2018 Preview SW winter diamond drilling program comprised 5 NQ diameter holes, totalling 810 metres, at the Preview North zone. The program was designed to test the interpreted down-plunge and down-dip continuity of gold mineralization identified during the 2017 winter and summer drilling programs (see Comstock news release dated September 28, 2017), and from 2013 drill hole PR13-183 (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). Visible gold was identified in four of the five holes drilled during the 2018 program, associated with sheared quartz-carbonate vein zones containing variable sulphide mineralization (arsenopyrite, pyrite +/-pyrrhotite).
Results from the 2018 program correlate well with previous results, and with the Preview North zone 3D mineralization model. Previous drilling has defined three principal parallel structures/vein zones along which the main mineralized intercepts occur, extending 350 metres along strike and up to a depth of 140 metres below surface. Higher grades intersected occur within a core zone over a strike length of approximately 170 metres.
The 2018 drilling program succeeded in identifying additional high-grade gold mineralization down-dip and along strike of previous drill holes, and enhances the understanding of the geometry of mineralization at Preview North. The current structural interpretation suggests the presence of steeply plunging high-grade gold zones at Preview North, however further work and interpretation is required to resolve the continuity of individual gold intercepts between holes.
The Company has integrated the new results from the Preview North zone into its project database along with geological data collected, and will incorporate the new information into the 3D model for Preview North to direct future exploration.
Significant weighted average intercepts are presented in Table 1. Hole locations are shown on Map 1 and Section 1, Section 2 and Section 3.
