Discovers New Vein Zone At Victor Target
Blackrock Gold Corp. (TSXV:BRC) has drilled multiple high-grade gold and silver core intercepts at its Victor Target on the 100% controlled Tonopah West project located in the Walker Lane trend of Western Nevada.
Highlights:
- At the Victor Target, a high-grade, multi-vein gold and silver zone has been drill-defined within an area 210 by 150 metres, and remains open to the west and down dip;
- Drillhole TW20-020C encountered 19 g/t gold and 1,634 g/t silver (3,534 g/t AgEq) over 0.9 metres near its target destination; however, it was abandoned at historic mine workings. (Silver:gold ratio is 100:1 using a 300 g/t AgEq cut-off grade);
- Drillhole TW20-031C cut 2.9 metres grading 1081 g/t AgEq; this intercept potentially represents a new vein system to the north of the Victor Target. This intercept connects with drillhole TW20-021C which hit 3.0 metres of 785 g/t AgEq. The two drillholes are separated horizontally by190 metres; and
- 24,000 metres in 48 drillholes are completed to date. Assays for 24 drillholes have been released, delivering 22 significant and high-grade intercepts ranging from 1 to 29 metres in thickness, with grades from 300 to 4,643 g/t AgEq. Sixteen intercepts have assayed at +500 g/t AgEq, with seven assayed at +1,000 g/t AgEq.
President and CEO Andrew Pollard said the company continues to hit phenomenal grades with itsdrilling as the mineralised zone at Victor Target expands, and a new high-grade vein zone has been identified.
“As the first group to target this historic mine since production shut down in 1930 due to low metals prices, we have refined our geologic model of the thick mineralised structure encountered in drillhole TW20-001 (29 metres grading 965 g/t AgE) and now believe the mineralized structure dips at a steeper angle than previously anticipated,” Mr Pollard said.
“We see significant expansion opportunities at this target, as we do our best to “thread the needle” around the historic workings with the drillbit to hit this structure down-plunge. In addition, with the large Pittsburg-Monarch fault encountered on the western extent of this significant, multi-vein, drill-defined zone, we also see significant expansion potential to the west should we be successful in targeting the offset vein system. With a number of completed drillholes pending assays from multiple target areas, we expect continuous newsflow through the end of the year.”
Drilling at the Victor Target has encountered high-grade mineralisation within a defined area of 210m by 150m. The objective is to offset the down-dip and down-plunge extensions of the gold and silver zone that was last mined in 1930 and find the off-set portion of the mineralized body to the west on the footwall of the Pittsburg-Monarch fault.
The drillholes have intersected significant gold and silver grades in the hanging wall of the fault. The gold and silver occur along the contact with the West End Rhyolite and the Extension Breccia, and the orientation of the contact is approximately 45 degrees but rolls to a steeper angle down dip and to the north. Drilling is complex, as historic workings in the upper levels interfere with access to the steeper portions of the body. As our model continues to refine, so will the targeting.
Drillholes TW20-011C and -013C encountered the Pittsburg-Monarch fault before the mineralized contact. They show no significant values on the footwall of the fault at that location. TW20-012C clipped a portion of the mineralized zone just before drilling through the fault.
TW20-020C was lost at 593 metres after encountering a historic underground working. TW20-024C hit a major fault and an extremely broken zone where the barrel and bit twisted off. Because the tools were left in the hole, it could not be advanced, and the hole was terminated.
TW20-021C is located 210 metres northwest and TW20-031C is located 150 metres northeast of TW20-001. The area in between these three holes shows potential for significant grade and new vein discovery. The intercept at TW20-021C, 3.0 metres of 785 g/t AgEq, is extremely exciting, as it may represent a new vein system to the north of Victor Target. This may be an extension of the intercept cut in TW20-031C, 2.9 metres grading 1081 g/t AgEq. TW20-051C was lost at 104 metres due to swelling clays at the top of the drillhole within the Mizpah andesite. A second core hole in this area, TW20-061C, is currently underway.
