PREVIEW SW GOLD PROJECT, SASKATCHEWAN
Comstock announced that it had closed the acquisition of the Preview SW gold project on September 14, 2016. Comstock holds a 100% interest in the Preview SW project, subject to a 2.5% NSR of which an initial 1% may be purchased for $1 million and the remaining 1.5% for $2 million at any time prior to a production decision. In addition, milestone payments are due to the original vendor upon completion of a positive feasibility study and upon a production decision.
The 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 Preview SW project database contains results from 162 core holes, totaling 26,250 m, drilled between 1985 and 2013. Of these, 136 were drilled on the main Preview SW deposit and form the basis for a current NI 43-101 resource estimate1 that includes:
- Indicated resources containing 158,300 ounces of gold (2.61 million tonnes grading 1.89 g/t Au) based on a 0.50 g/t Au cut-off grade.
- Inferred resources containing 270,800 ounces of gold (5.70 million tonnes grading 1.48 g/t Au) 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, 500 m in strike length and totaling 150 m in width. Preliminary metallurgical test work indicates total gold recovery in concentrates ranged from 90% to 93%1.
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 (see Comstock’s September 14, 2016 News Release) 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
There has been insufficient drilling at the Preview North zone to determine the attitude of the reported mineralized intervals and, therefore, the above mineralized intersections may not represent true widths. No drilling has been carried out for over 600 m to the south of this hole.
Comstock is currently engaged in an aggressive winter 2017 exploration program at Preview SW which includes ground geophysics, step-out drilling around the deposit, drilling at the Preview North zone as well as sampling for additional metallurgical test work.
