Blackrock Drills 3 Metres of 2,198 G/T Silver EQ. in New Vein and Extends Victor Vein Down Plunge with 29 Metres Grading 965 G/T Silver EQ. on the Tonopah West Project

Vancouver, British Columbia--(Newsfile Corp. - July 20, 2020) - Blackrock Gold Corp. (the "Company") is pleased to announce initial drill results from the Victor target on its 100% controlled Tonopah West project located in the Walker Lane trend of Western Nevada.

HIGHLIGHTS:

  • Drillhole TW20-001 intersected a new vein yielding 3 metres grading 2,198 g/t silver equivalent (silver :gold ratio 100:1) using a 400 g/t silver equivalent cut-off grade;
  • Drillhole TW20-001 also extended the Victor Vein 30 metres down plunge with the intersection of 965 g/t silver equivalent over 29 metres;
  • Two additional drillholes are completed at the Victor Vein target to test the down plunge extension (assays pending);
  • A core drill is being mobilized to site to follow up on TW20-001's outstanding results;
  • Drilling is on going at the Denver, Paymaster and Bermuda (DPB) target with three of eight drillholes completed and one in progress; and
  • The New Discovery and Ohio Vein targets remain untested at this time.

Andrew Pollard, President & CEO commented, "As the first group to target the historic workings within this prolific, historic silver district in the heart of Nevada, our first drillhole, having encountered multiple significant high-grade veins, is nothing short of remarkable. With six drillholes now completed in two distinct target areas, we are incredibly encouraged, as our modelling of the vein systems appears to line up as predicted. Given these encouraging initial results, we are mobilizing a core drill rig and expanding our initial drill program beyond the previously envisioned 7,000 metres."

Three reverse circulation drillholes are complete in the Victor Vein area targeting the down-plunge extension of a mineralized shoot that is 20 metres wide, 200 metes long, and is open down-plunge. Drillhole TW20-001 is the first of three drillholes to test this target.

TW20-001 targeted the down-plunge extension of the Victor Vein silver and gold zone. The drillhole intersected this zone which dips 45 degrees to the northwest starting at 574.5 metres down the drillhole. The drillhole was designed to intersect the zone 50 metres down-plunge; however,it intersected at 40 meters due to deviation. The drillhole terminated unexpectedly in historic workings. The workings indicate mining of the zone in the 1920's may have continued if not for technical issues apparently caused by unreliable power to pump the water.

In addition, two previously unknown veins were intersected above the main Victor zone. The first returned 3 metres grading 465 g/t silver equivalent, and the second yielded 3 metres grading 2,198 g/t silver equivalent. All zones carried quartz vein material with black sulphides associated with the quartz veins.

TW20-002 and -003 also intersected vein material with black sulfides. Assay results are pending. If positive, TW20-002 and -003 will extend the mineralized zone an additional 170 metres down-plunge.

The Company is securing a core drill to follow up on the Victor target results. The drill will arrive on site in August, and a program totalling 1,000 to 2,000 metres is being designed.

As a re-cap, the Company is testing four exploration target areas, Victor, DPB, New Discovery, and Ohio, which have a total of 2.5 million to 6 million tonnes with an average grade of 1300 to 2100 g/t silver and silver equivalent. The potential quantities and grades of the exploration target zones set out below are conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain whether further exploration will result in the targets being delineated as mineral resources. The exploration target zones are as follows:

  1. Victor Target: on the northern portion of the property at the Victor shaft, the underground workings encountered a confluence of high-grade veins on the 1880 level with widths up to 24 metres where production shut down[1]. The exploration target is the thick, high-grade series of veins below the 1880 level. The exploration target ranges from 0.5 million to 1 million tonnes averaging 1500 to 3000 g/t silver and silver equivalent. TW20-001, -002, and -003 are testing this target, and one additional drillhole is planned. The potential quantities and grades of the exploration target zone are conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain whether further exploration will result in the exploration targets being delineated as mineral resources.;
  2. DPB Target: through the McKane shaft, three veins, Denver, Paymaster, and Bermuda, were mined from 1200 to the 1650 level. Geologic and assay reports indicate additional mineralization down-dip from the 1650 to 1880 level, possibly down to the 2150 level. Gold and silver are open to the west along strike. Ten drillholes will test for veins in the Mizpah and West End Rhyolite lithologies. The target area is envisioned to contain from 1 million to 3 million tonnes averaging 1000 to 1500 g/t silver and silver equivalent. The potential quantities and grades of the exploration target zones are conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain whether further exploration will result in the exploration targets being delineated as mineral resources.;
  3. New Discovery Target: In 1997, a new discovery in the southwest quadrant of the property was identified using RC drilling (7.5 g/t gold and 288 g/t silver over 3 metres). Follow-up drilling in 2018 cut two 1.5 metre zones grading 9.7 g/t gold, 715 g/t silver and 4.6 g/t gold, 401 g/t silver. These zones are within the same stratigraphic package as the Ohio vein located 1.5 kilometres to the east and may represent a similar flat-lying vein with a similar target ranging from 0.5 million to 1 million tonnes averaging 1500 to 3000 g/t silver and silver equivalent. Four drillholes are planned to test this exploration target. The potential quantities and grades of the exploration target zones are conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain whether further exploration will result in the targets being delineated as mineral resources.; and
  4. Ohio Target: drilling is planned in the southeast portion of the property where the flat-lying Ohio vein was mined from the Ohio shaft. No geologic work to find the vein offset by the Monarch-Pittsburgh fault has been completed, and potential exists for the strike extension of the Ohio vein to the west. The vein dips 20 degrees to the south, and the exploration target ranges from 0.5 million to 1 million tonnes averaging 1500 to 3000 g/t silver and silver equivalent. Four drill holed are planned to test this exploration target. The potential quantities and grades of the exploration target zones are conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain whether further exploration will result in the targets being delineated as mineral resources.

All sampling was conducted under the supervision of the Company's project geologists, and a strict chain of custody from the project to the sample preparation facility was implemented and monitored. The RC samples were hauled from the project site to a secure and fenced facility in Tonopah, Nevada, where they were loaded on to American Assay Laboratory's (AAL) flat-bed truck and delivered to AAL's facility in Sparks, Nevada. A sample submittal sheet was delivered to AAL personnel who organized and processed the sample intervals pursuant to the Company's instructions. Blackrock personnel inserted standards and blanks into the sample sequence.

The RC samples and QA/QC samples were crushed and pulverized, then the pulverized material was digested and analyzed for gold using fire assay fusion and an Induced Coupled Plasma (ICP) finish on a 30-gram assay split. Silver was determined using five-acid digestion and ICP analysis. Data verification of the assay and analytical results are completed to ensure accurate and verifiable results. A prep blank, lab blank or a certified standard was inserted approximately every 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.
