from Resource Expansion Program
HIGHLIGHTS:
TXC25-144 cut 10.12 metres grading 467 grams per tonne (g/t) silver equivalent (AgEq)
(283 g/t silver (Ag) & 2 g/t gold (Au)), including 3.51 metres of 1,020 g/t AgEq (620 g/t Ag &
4.43 g/t Au);
TXC25-145 encountered multiple zones of high-grade mineralization which included 0.67
metres of 3,264 g/t AgEq (2,008 g/t Ag & 13.93 g/t Au) within 11.58 metres grading 327 g/t
AgEq (186 g/t Ag & 1.56 g/t Au) and 2.32 metres grading 401 g/t AgEq (242 g/t Ag & 1.76 g/t
Au);
TXC25-153 drilled 0.7 metres of 724 g/t AgEq (437 g/t Ag & 3.18 g/t Au) within 5.73 metres
of 156 g/t AgEq (96 g/t Ag & 0.67 g/t Au);
Step-out drilling has established continuity of high-grade gold & silver mineralization
over significant widths that runs 500 metres along drill-defined strike from the existing
DPB resource shell to the northwest; and
Targeting is now underway to bridge mineralization on remaining 500 metres of vein
corridor to NW Step Out resource area.
Vancouver, British Columbia--(Newsfile Corp. - July 8, 2025) -
Blackrock Silver Corp. (TSXV: BRC)
(OTCQX: BKRRF) (FSE: AHZ0)
("
Blackrock
" or the "
Company
") announces the final set of assay
results from its Resource Expansion Program (defined below) showing significant width and high-grade
silver and gold drill intercepts in step-out drilling at its 100% owned Tonopah West project ("
Tonopah
West
") located in Nye and Esmeralda Counties, Nevada, United States.
Blackrock's resource expansion program at Tonopah West (the "
Resource Expansion Program
"),
which commenced in September 2024, consisted of 18 drillholes totalling 10,802 metres (35,438 feet)
of drilling, targeted expansion potential along a one-kilometre northwest trend between the Denver-
Paymaster and Bermuda-Merten vein groups ("
DPB
") south resource area and the Northwest ("
NW
")
Step Out resource area.
The aim of the Resource Expansion Program is to increase the size of the Tonopah West resource
footprint and to allow evaluation and inclusion of the NW Step Out resource in an updated preliminary
economic assessment to be completed on Tonopah West. This final batch of assay results from the
Resource Expansion Program tracked high-grade gold and silver mineralization across significant
widths spanning 500 metres from the existing DPB resource area to the northwest.
Andrew Pollard, the Company's President and Chief Executive Officer, stated: "Final assays from our
Resource Expansion Program have confirmed thick, high-grade silver and gold mineralization extending
500 metres beyond the current DPB resource, with standout intercepts including 10.1 metres grading
467 g/t AgEq and 11.6 metres of 327 g/t AgEq. These results reinforce the scale and continuity of the
NW vein system and underscore the strong potential to materially expand the resource and extend mine
life at Tonopah West. With our geologic model in hand, drill targeting is now underway for the remaining
500-metre gap of vein corridor that aims to fully bridge mineralization to our NW Step Out deposit."

The NW vein system is located along contacts between lithologic units and forms a wide anastomosing
and intersecting network of veins and breccias within the West End Rhyolite package.
The veins dip
approximately 55 degrees to the northeast and show excellent continuity over approximately 500 metres
of strike.
TXC25-124, -144, and TXC25-145 have especially wide zones above the 150 g/t AgEq cut off.
TXC25-
154 returned an exceptionally wide zone of low-grade over 17.1 metres with 0.154 g/t Au and 25.8 g/t
Ag. These drillhole intercepts show the system has strength and ability to mineralize a large volume of
rock.
The position, orientation and character of the NW vein system is consistent with the outer ring structure of
the Fraction caldera marked farther south by the Merten vein.
The mineralization is open to the northwest
and down dip to the northeast giving ample room for additional resource expansion of the Tonopah West
silver and gold system.
Geologic cross sections are being constructed to better understand the silver and gold system to the
northwest.
Targeting is now underway to bridge mineralization on remaining 500 metres of vein corridor
to NW Step Out resource area.

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.
