Blackrock Gold Corp (CVE:BRC) (OTCMKTS:BKRRF) has resumed exploration at its Silver Cloud project in Nevada after work was halted due to the coronavirus pandemic.
The Vancouver-based company reported new assay results from drill hole SBC20-06, which was “crucial” to Blackrock’s understanding of the mineralized structure, CEO Andrew Pollard said in a statement.
SBC20-06 was drilled to intersect the Northwest Canyon east-west zone at depth and intersected a 25.1-metre alteration zone from 426 to 451.1 metres down the hole. Alliteration consisted of quartz and sulphide veinlets ranging between 6 millimetres to more than 100 millimetres over the length of the alteration zone with veinlets occurring every 1.5 to 2.5 metres within the interval, according to a release.

Assay results revealed gold values up to 0.450 parts per million (ppm) gold, and a section measuring 3.5 metres and grading 0.34 grams per tonne gold was returned starting at 426 metres down the hole using a 0.2 gram per tonne gold cutoff. The entire 25 metre zone returned an average grade of 0.121 grams per tonne gold using a 0.1 gram per tonne cutoff.
In a statement, Pollard said that Blackrock’s objectives with SBC-006 included targeting the mineralized structure thought to have been previously encountered too high up in the epithermal system, down dip within the projected boiling zone, and understanding the depth of the Ordovician basement lithologies in area to further define the geometry of the volcanic basin and assist with ongoing and future targeting.
“We were successful in hitting the structure down dip precisely as modelled, though it's evident we encountered it within a rock package that isn't ideal for a vein formation,” Pollard told investors.
“This hole has been crucial to us in terms of understanding what this epithermal system looks like at depth, and by identifying the top and bottom of this mineralized zone, we are able to refine our targeting in search of the ‘Goldilocks horizon’.”
Upcoming work on Silver Cloud includes property-wide IP surveys and a detailed mapping and sampling program at the Northeast Veins and Quiver targets. The company is planning a 3,500-metre RC drilling program, consisting of 10-12 drill holes is slated to begin in September.
