Comstock begins diamond drilling program at Preview SW Gold Project in Canada

Published 08 March 2017

Comstock Metals announces that it is commencing a minimum 2500m diamond drilling program at its Preview SW gold project, located 40km north of La Ronge, Saskatchewan.

The Company also reports that it has carried out a Horizontal Loop Electromagnetic (HLEM) survey designed to assist in positioning drill holes to best test high priority targets.

Diamond Drilling

The drilling program will initially target the Preview North or Adit target where previously reported 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. No drilling has been carried out for over 600 m to the south, along trend of this hole. Additional drilling will test targets peripheral to the Preview SW mineral resource area, approximately 2.6 kilometres to the southwest and along the mineralized corridor that links the two areas.

Comstock has retained Apex Geoscience Ltd. to manage the drill program and Minotaur Drilling Inc. has been contracted to provide drilling services.

Geophysical Survey

The HLEM survey was carried out over three separate grid areas which include: 1) the Preview North (Adit) zone at the northeast end of the property where initial focus of the drilling program will be to follow up on high-grade drill hole PR13-163, 2) the northern end of the Preview SW deposit to cover the mineralized trend through to its potential extension towards the A zone, 300 m northeast, and 3) the southern margin of the Preview SW deposit (see below description of the Preview SW property in About Comstock section). Patterson Geophysics Inc. was contracted to carry out the survey using a MaxMin I+9. A total of 23.5 line kilometers was surveyed. Seven different frequencies were measured with two passes utilizing 100 and 200 m coil separation carried out along lines spaced between 100 m and 50 m apart. In addition, 3D inversions have been completed on data from an aeromagnetic survey carried out in 2012 and on data from three induced polarization/resistivity grids completed on the property in 1989.
