Vancouver, British Columbia--(Newsfile Corp. - November 21, 2024) -
Blackrock Silver Corp. (TSXV:
BRC) (OTCQX: BKRRF) (FSE: AHZ0)
("
Blackrock
" or the "
Company
") is pleased to announce the
second set of assay results from the M&I Conversion Program (as defined herein) on the Company's
100% owned Tonopah West project ("
Tonopah West
") located within the prolific Walker Lane trend in
Esmeralda and Nye Counties adjacent to the town of Tonopah, Nevada, USA.
The Company is completing an in-fill drilling campaign (the "
M&I Conversion Program
") consisting of
forty drillholes within the shallow southern portion of its' DPB resource area with an aim to convert up to
1.5-million tonnes of material to the measured and indicated mineral resource category, with the drillhole
pattern being implemented on 25-metre centers. This area represents the initial years of proposed
production based on the mine plan laid out in the Company's recently announced preliminary economic
assessment for Tonopah West (see news release dated September 4, 2024).
The M&I Conversion Program commenced in late July 2024 pursuant to which the Company has
completed 32 of the planned 40 drillholes.
An additional 6 core holes from surface have been added to
the M&I Conversion Program to follow up on high-grade intercepts encountered in TXC24-087.
Pursuant
to the M&I Conversion Program, a total of 10,283 metres (33,737 ft) of drilling have been completed to
date and the Company has received assays for 27 of the 34 drill holes completed (see Table 1 below for
all assay results received to date from this program).
Andrew Pollard, the Company's President and CEO, stated, "Multiple high-grade zones are emerging on
our Merten vein system as additional results from our ongoing M&I Conversion Program continue to
increase confidence in our model. Near surface mineralization has been tracked from 137 metres down
to 367 metres downhole, with each distinct zone delivering intercepts beyond 2,000 g/t AgEq while
establishing exceptional continuity along the vein. Additional high-grade mineralization has been
identified up-dip which appears to connect to a once thought isolated zone to the east (TW21-076: 4.6
metres grading 510 g/t AgEq). The M&I Conversion Program is targeting up to 1.5 million tonnes of
material for potential conversion. Additional drillholes are being added to this fully-funded program to
follow up on TW21-076.
Drills are poised to remain at site through the end of the year and into Q1 2025,
and with many completed drillholes pending assays, we expect to finish 2024 on a strong note."

The M&I Conversion Program establishes continuity of the high-grade zone within the Merten vein.
Two
additional zones are coming together and showing that Merten has potentially three high-grade silver
and gold zones based on the drill results received to date.
Figure 1 below illustrates a long section along
the Merten vein illustrating grade times thickness, demonstrating the high-grade silver equivalent zones
have up to 200 metres of length across the Merten vein structure.
TXC24-077, -078, 079, -082, -088, -089, -093, -096, -097 and TXC24-099 returned silver and silver
equivalent assay intervals albeit below the 150 g/t AgEq cut-off grade. In these core holes: (i) gold values
range from 1.45 to 0.185 g/t Au; (ii)
silver values range from 91.9 to 3.4 g/t Ag; and (ii) silver-equivalent
values range from 222.4 to 32.5 g/t AgEq, with drillhole intervals between 4.7 and 0.6 metres.
Although
the assays are below the cut-off grade, the low-grade intercepts confirm the modelled vein geometries
and thicknesses along the Fraction caldera margin, and help to define the high-grade chutes within the
Merten vein.
An additional high-grade silver equivalent zone has emerged to the east of the M&I Conversion Program
drilling area, and the Company's plans to drill additional drillholes in 2025 to follow up on this isolated
intercept along the Merten vein.

The drilling conducted pursuant to the M&I Conversion Program utilized a reverse circulation (RC) to drill
to complete pre-collar drillholes to various depths and then core tails to drill through the modelled target
zones in DBP area.
TXC24-079, -089, -090 and 105 encountered voids in the drilling.
The voids are the result of fault
fractures and potentially old workings.
The cavities were between 2 to 6 metres in width.
The larger
cavity caused TXC24-090 to be terminated prematurely.
The M&I Conversion Program is completing 2 to 3 core tails per week with lab turn around at roughly 6 to
8 weeks.
With 34 drillholes completed to date, there are seven drillholes with assays pending. RC pre-
collars have been completed for eleven holes that are awaiting core tails. Additional assay results from
the M&I Conversion Program will be forthcoming over the next several months.

Quality Assurance/ Quality Control
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 RC and
core 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 RC samples are lined out at the lab and logged in to AAL's system.
The core samples are cut using
core saws and personnel at AAL's facility in Sparks, Nevada according to the Company's instructions
delivered with each core hole.
All samples are dried, crushed to 85% passing 10 mesh (2mm) and a 250-gram sub-sample split is
collected and pulverized to 200 mesh (74 micron) in a ring and puck pulverizer.
Then the pulverized
material is digested and analyzed for gold using fire assay fusion and an Induced Coupled Plasma (ICP)
finish on a 30-gram assay split (FA-PB30-ICP). Silver is determined using five-acid digestion and ICP
analysis (ICP-5AM48).
Over limits for gold and silver are determined using a gravimetric finish
(GRAVAU30 and GRAVAG30).
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 reference material approximately every 15th to 20th sample.
