Blackrock Reports Complete 2019 Drill Results at Silver Cloud; Commences Follow-up Drill Program
Blackrock Reports Complete 2019 Drill Results at Silver
Cloud; Commences Follow-up Drill Program
Press Release Highlights
Drillholes SBC19-001, -004 and -005 from the Silver Cloud mine area have identified mineralized zones of up to 6.1
metres in thickness at depth indicating the veins and fractures are coalescing down dip into thicker zones;
Drill data shows the volcanic rock package thickens to the west, suggesting the boiling zone could be within the more
favourable rhyolite host;
The 3.93 g/t and 8.32 g/t gold intervals in SBC19-001 and SBC19-002 over 0.8 metres and 1.5 metres respectively, of
which are 1.5km apart, are interpreted to be within the upper levels of the epithermal system; and
Drilling has commenced on the follow-up program to test the Northwest Canyon east-west structure down dip and aims to
expand upon the newly delineated 250m strike to the west.
Vancouver, British Columbia--(Newsfile Corp. - March 11, 2020) -
Blackrock Gold Corp. (TSXV: BRC) (the "
Company
") is
pleased to report final assay results and geologic interpretation on its 100% controlled Silver Cloud project located on the
Northern Nevada Rift in Elko County, Nevada.
Five HQ core holes were drilled at Silver Cloud totalling 2,207 metres (7,240 feet), and
assay results have been received for all
(See Table 2).
The drill program focused on evaluating a potential east-west vein system between the Silver Cloud mercury mine
and Northwest Canyon, with all five holes returning gold assays above the 0.2 g/t gold cut off grade over significant drill widths.

Andrew Pollard, President & CEO, commented, "With one small drill program under our belt, we have established our
understanding of the east-west orientation of the epithermal vein system, delineating for the first time on our property a drill-
defined mineralized strike of 250 metres, that appears to be open both along strike and down-dip.
With a complete picture from
our 2019 drill program now in hand, it's evident we encountered the structures too high in the epithermal vein system. We are
excited to see the drills turning once again as we have refined our aim in search of the boiling zone where the potential for
bonanza grade gold, for which the Northern Nevada Rift is well documented, may exist.
The thicker mineralized zones encountered at depth are very encouraging to us.
The gold system we've encountered appears to
be behaving as the epithermal gold model would predict when encountered at the upper levels, providing us a roadmap to use in
our targeting of the follow-up program as we aim to zero in on a potential high-grade gold horizon. The 2020 program is
targeting the structure at deeper elevations within the thicker volcanic package at Northwest Canyon. We believe the structure
has the potential to host high-grade gold and silver within a boiling zone deeper in the system, as indicated by the exploration
model, with the objective to intercept mineralized intervals ranging from 2 to 6 metres in thickness."
Downhole geophysical surveys show east-west oriented veins and fractures in the mineralized zones in SBC19-002 and -003 at
Northwest Canyon.
The mineralized structure is steeply dipping to the south and has a drill-defined strike length of 250 metres
(see March 03, 2020, news release).
Drilling has commenced on the 2020 spring drill program which has been designed to test the Northwest Canyon east-west
structure down dip and along strike to the west.
At Northwest Canyon, the volcanic units are thicker than those encountered to the east, and an altered and mineralized rhyolite
porphyry flow domes intrude the volcanic pile.
Drilling to date has not encountered the basement lithologies.
Northwest Canyon
has a similar geologic setting to the nearby Midas mine where high-grade gold and silver mineralization are co-eval with the
rhyolite flow domes which may have provided the heat source to drive the hydrothermal system.
The flow domes at Midas intrude
a thick sequence of rhyolite volcanic units that are similar to the geology intersected in the Northwest Canyon drillholes.
Mineralization hosted on adjacent or nearby properties is not necessarily indicative of the mineralization hosted on our property.
The 2020 drill program will determine the depth of the Ordovician basement lithologies; this should define the geometry of the
volcanic basin and assist with ongoing and future targeting.

The 2019 drill program encountered significant silver intercepts (See Table 3).
The bulk of the silver assays were intersected in
SBC19-001 which returned 4.88 metres averaging 14.0 ppm silver.
The highest silver value returned was 40.8 ppm from a
deeper intercept in SBC19-001.
Although no intervals assayed over 5 ppm silver in SBC19-002, 1.40 ppm was reported from
the interval with 8.32 g/t gold.

All core 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 core boxes were hauled from the project site
to a secure facility in Battle Mountain, Nevada, where the core was logged, and samples intervals selected, cut and bagged
under the supervision of Blackrock's project geologist.
The samples were delivered to American Assay Laboratory or picked up
by American Assay Laboratory delivered to their facility in Sparks, Nevada.
After receipt, they were crushed and pulverized, then
the pulverized material was digested and analyzed for gold using fire assay fusion and an atomic absorption spectroscopy
(AAS) finish on a 30-gram assay split. Silver determinations were completed using two-acid digestion and ICP (inductively
coupled plasma) analysis. Data verification of the assay and analytical results are completed to ensure accurate and verifiable
results. A blank, duplicate or a certified standard was inserted approximately every 15th sample.
Blackrock's exploration activities at the Silver Cloud 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.
