Blackrock Reports Multiple Significant Intercepts Including 3m of 2,238 Silver Eq and Initiates Resource Definition Program on the DPB Target at Tonopah West
Vancouver, British Columbia–(Newsfile Corp. – December 3, 2020) – Blackrock Gold Corp. (TSXV: BRC) (the “Company“) is pleased to announce additional high-grade gold and silver drill intercepts from its Denver, Paymaster and Bermuda (DPB) Target on the 100% controlled Tonopah West project located in the Walker Lane trend of Western Nevada.
- TW20-037 cut 3 metres returning 10.5 g/t gold and 1,188 g/t silver or 2,238 g/t AgEq along the Merton vein and indicates 290 metres of dip potential. Silver:gold ratio is 100:1 using a 200 g/t AgEq cut-off grade;
- TW20-027 drilled 12.2 metres grading 297 g/t AgEq at Bermuda-Merton vein intersection;
- TW20-022 intersected 4.5 metres grading 285 g/t AgEq on the Paymaster vein;
- Drilling defines mineralization over 300 metres along the Paymaster vein;
- All DPB veins are open to the east and west, as well as up and down dip;
- A resource definition program is being coordinated to deliver an initial resource on DPB by YE 2021; and,
- Additional assays are pending from the DPB and Victor Targets.
Andrew Pollard, President & CEO commented, “As more high-grade results continue to roll in from our DPB Target, this zone is now really starting to take shape, highlighting significant resource potential. Drilling continues to confirm our geologic model, and as we’re now establishing continuity and mineralization of the many tightly-spaced veins in this corridor, all of which remain open, we’re putting together an extremely aggressive plan that will see us fast-track to deliver an initial resource estimate before the end of 2021. This is a transformational step for any project, and moving from a maiden round of drilling to resource delineation mode so quickly underscores the calibre of this target, providing investors with something compelling to look forward to over the next twelve months. With more drill results pending in the short-term, from both our Tonopah West and Silver Cloud projects, we look forward to significant news flow to end the year.”

Drilling at the DPB Target continues to deliver significant gold and silver results. TW20-027 returned 12.2 metres grading 297 g/t AgEq at the intersection of the Bermuda and Merton veins, and, this intercept was followed by a 3 metre interval yielding 312 g/t AgEq. The Bermuda-Merton intersection appears to have a series of stringer veins around the main junction, thus bulking up the zone.
On the Merton vein, TW20-037 cut another significant interval with gold grades above 10.51 g/t gold and 1,187.5 g/t silver over 3 metres. This interval is up-dip from the 4,643 g/t AgEq interval reported in TW20-017. TW20-035 was lost prior to intersecting the target, and a second drillhole is planned.
Drilling on the Merton vein has defined a zone striking 120 metres east-west with a dip length of 290 metres. The Merton vein is open to the northwest and southeast, while the Bermuda vein is open to the east and west. Mineralization on both veins is open up-and down-dip.
TW20-006, -022 and -023 define 300 metres of strike along the Paymaster vein, and the next set of drillholes are chasing the vein to the west toward the TW20-016 step out target. The Paymaster vein is open to the east and west.
TW20-030 and -033 drilled intercepts along the Denver vein which is open to the east and west.
23 drillholes are completed at the DPB Target, with assay results available for 19 drillholes. Drilling is progressing along north-south oriented cross sections that are 150 metres apart.
Given our initial exploration success at Tonopah West which demonstrates significant potential, the Company is planning a resource development phase program for the DPB Target, with a goal to have an initial resource estimate in Q4 2021.
Four drillholes are completed at the Ohio Target, including TW20-028 and TW20-029 which intersected the Ohio vein; however, gold and silver assays ranged from 20 to 36 g/t AgEq and are below the 200 g/t AgEq cut off grade in Table 1.
TW20-032 intersected a historic underground working where the vein was projected (looks like they beat us to it) and assays returned no significant values for TW20-025.
The drilling refined the location of the Pittsburg-Monarch fault zone, and an updated geologic interpretation is underway to find the offset portion of the Ohio vein.
Initial core drilling intercepts at the Victor Target were released on November 23, 2020. Drilling encountered high-grade mineralization within a defined area of 210 by 150 metres. Assays for TW20-041C are pending, and TW20-061C is in progress.
Drillhole TW20-039 is part of the step out program following up TW20-016. TW20-039 encountered two zones with elevated gold ranging 0.74 to 1.1 g/t gold within three distinct intervals; however, silver values were not the usual 100:1 as seen in the rest of the district. Silver ranged from 3 ppm to 65 ppm. The gold mineralization may represent a younger gold system similar to the Three Hills project located immediately south of and adjoining Tonopah West.

All sampling is conducted under the supervision of the Company’s project geologists, and a strict chain of custody from the project to the sample preparation facility is implemented and monitored. The core and reverse circulation samples are hauled from the project site to a secure and fenced facility in Tonopah, Nevada, where they are loaded on to American Assay Laboratory’s (AAL) flat-bed truck and delivered to AAL’s facility in Sparks, Nevada. A sample submittal sheet is delivered to AAL personnel who organize and process the sample intervals pursuant to the Company’s instructions.
The core, reverse circulation, and QA/QC samples are crushed and pulverized, then the pulverized material is digested and analyzed for Au using fire assay fusion and an Induced Coupled Plasma (ICP) finish on a 30-gram assay split. Silver is determined using five-acid digestion and ICP analysis. Over limits for gold and silver are determined using a gravimetric finish. Data verification of the assay and analytical results are completed to ensure accurate and verifiable results. Blackrock personnel insert a blind prep blank, lab blank or a certified standard approximately every 15th to 20th sample.
Blackrock’s exploration activities at the Tonopah West Project are being conducted and supervised by Mr. William Howald, Executive Chairman of Blackrock Gold Corp. Mr. William Howald, AIPG Certified Professional Geologist #11041, is a Qualified Person as defined under National Instrument 43-101. He has reviewed and approved the contents of this news release.
