Blackrock Silver Begins Placement of

Hydrologic Monitoring Wells at Tonopah West

The collection of hydrologic data from piezometers is a crucial

step in obtaining permits for the proposed exploration

decline, test mining and bulk sample extraction at Tonopah

West

Vancouver, British Columbia--(Newsfile Corp. - May 15, 2025) -

Blackrock Silver Corp. (TSXV: BRC)

(OTCQX: BKRRF) (FSE: AHZ0)

("

Blackrock

" or the "

Company

") announces commencement of a

core drilling program for piezometer instrumentation installation, which is a critical path item for the

permitting process of the proposed exploration decline, test mining and bulk sample extraction at the

Company's Tonopah West project ("

Tonopah West

") located in Nye and Esmeralda Counties, Nevada.

The Company's hydrologic program includes four core holes, totalling 1,565 metres (5,150 ft). Each

drillhole will contain multiple piezometers strategically placed to measure water flow along faults,

lithologic contacts and within specific lithologies along the projected alignment of the proposed decline.

The data collected from these piezometers will help address questions related to water management in

an underground mine, including information for required permits, engineering design and water disposal.

The hydrologic program aims to gather critical hydrologic data to support the permitting and

development phases of Tonopah West. This initiative highlights Blackrock's commitment to advancing

Tonopah West while adhering to stringent environmental and regulatory standards. The data collected

from these piezometers will inform the design and management of the proposed exploration decline and

assist in optimizing the design for safety and efficiency.

"The initiation of our hydrologic program marks a pivotal milestone as we continue to advance our high-

grade Tonopah West silver-gold asset towards development," commented Andrew Pollard, President

and Chief Executive Officer of Blackrock. "The installation of these monitoring wells is a critical

component in unlocking the permitting process for our proposed exploration decline and test mining. By

gathering essential hydrologic data, we're not only optimizing our mine plan for efficiency and safety but

also reinforcing our commitment to responsible development as we aim to build a project that meets the

highest regulatory and sustainability standards."

other than statements of historical fact, are forward-looking statements. Forward-looking statements in

this news release relate to, among other things: the Company's hydrologic program and the intended use

of the information gathered therefrom; exploration, permitting and test mining at Tonopah West; and the

Company's strategic plans.

These forward-looking statements reflect the Company's current views with respect to future events and

are necessarily based upon a number of assumptions that, while considered reasonable by the

Company, are inherently subject to significant operational, business, economic and regulatory

uncertainties and contingencies. These assumptions include, among other things: conditions in general

economic and financial markets; accuracy of assay results; geological interpretations from drilling

results, timing and amount of capital expenditures; performance of available laboratory and other related

services; future operating costs; the historical basis for current estimates of potential quantities and

grades of target zones; the availability of skilled labour and no labour related disruptions at any of the

Company's operations; no unplanned delays or interruptions in scheduled activities; all necessary

permits, licenses and regulatory approvals for operations are received in a timely manner; the ability to

secure and maintain title and ownership to properties and the surface rights necessary for operations;

and the Company's ability to comply with environmental, health and safety laws. The foregoing list of

assumptions is not exhaustive.

The Company cautions the reader that forward-looking statements involve known and unknown risks,

factors include, without limitation: the timing and content of work programs; results of exploration

activities and development of mineral properties; the interpretation and uncertainties of drilling results

and other geological data; receipt, maintenance and security of permits and mineral property titles;

environmental and other regulatory risks; project costs overruns or unanticipated costs and expenses;

availability of funds; failure to delineate potential quantities and grades of the target zones based on
