Comstock said the programme successfully infilled an open area of the resource model, extended the deposit to the north-east, and intersected high grades - including 0.9m at 208g/t gold - in a 45m down-dip step back on section targeting ultra-high grade gold.
A previous highlight from this high-grade section included 1,123g/t gold over 2.3m back in 2013, which continues to outshine the latest results.
The headline intercept was from infill drilling and had intercepted multiple close-spaced vein zones, with one interval including 3.5m at 6.62g/t.
The Preview SW gold project has an indicated resource of 2.61 million tonnes grading 1.89g/t gold and Comstock is now planning a summer programme.
The company wrapped up an RAB drilling programme late last year at its QV gold project in the Yukon, which has a 4.4 million tonne inferred resource grading 1.65g/t gold, to turn its attention to Preview SW.
Comstock's share price, which has ranged between C12-43c over the past year, closed down 5.88% at 16c, capitalising the company at C$11.75 million.
