Key Terms

reverse circulation, diamond core drilling, fire assay fusion, Induced Coupled Plasma (ICP), +3 more

7 terms

reverse circulation technical

"utilizing reverse circulation (RC) drilling with RC pre-collars"

Reverse circulation is a drilling method used in mineral exploration where rock fragments are lifted to the surface inside an inner tube while drilling, keeping samples cleaner and faster than conventional techniques. Investors care because it provides quicker, more reliable samples for estimating how much mineral or ore might be present, reduces exploration costs and drilling time, and therefore can speed up or improve the quality of resource assessments that drive project value.

diamond core drilling technical

"deepened using diamond core drilling (core tails) for more detailed"

Diamond core drilling is a method of mining exploration that cuts a cylindrical plug of rock using a diamond-lined drill bit, producing an intact core sample like taking a tissue biopsy from the earth. Investors care because those samples are tested to show the type, concentration and continuity of minerals, which directly affects how much a deposit might be worth, how risky development is, and how confidently companies can plan budgets and timelines.

fire assay fusion technical

"analyzed for gold using fire assay fusion and an Induced Coupled"

Fire assay fusion is a laboratory method for measuring how much precious metal (like gold or silver) is in a rock or soil sample by melting the sample with reagents so the metals concentrate into a small bead that can be weighed. Investors care because it is one of the most reliable ways to determine the value and size of a mineral deposit—think of it as a precise weighing scale for hidden metal that underpins resource estimates and company valuation.

Induced Coupled Plasma (ICP) technical

"fire assay fusion and an Induced Coupled Plasma (ICP) finish on"

Inductively coupled plasma (ICP) is a laboratory technique that turns a sample into a hot, charged gas to measure which chemical elements and how much of each are present, similar to breaking a toy into parts to see what it’s made of. Investors care because ICP testing supports quality control, regulatory compliance and resource valuation—results can reveal contamination risks, product safety issues or the true mineral content that affect costs, liabilities and revenue forecasts.

gravimetric finish technical

"Over limits for gold and silver are determined using a gravimetric finish"

A gravimetric finish is a precise way of measuring the final weight of a product or material after processing or manufacturing. It ensures that the final amount meets exact standards, similar to weighing ingredients carefully in cooking. For investors, it indicates attention to quality control and consistency, which can impact a company's reputation and product reliability.

certified reference material technical

"insert a blind prep blank, lab blank or a certified reference material"

A certified reference material is a substance or sample with precisely measured properties and an official certificate that labs use to calibrate instruments and check testing accuracy, like a ruler for measurements. Investors care because reliable testing underpins product quality, regulatory approvals and compliance, and environmental or safety claims; using certified materials reduces the risk of costly recalls, failed audits or misleading results that can harm a company’s finances and reputation.

National Instrument 43-101 regulatory

"Qualified Person as defined under National Instrument 43-101 – Standards"

National Instrument 43-101 is a set of rules and guidelines that govern how mineral exploration and mining companies must report information about their projects. It ensures that the details shared with investors are accurate, consistent, and reliable—similar to how a detailed, verified blueprint ensures a building’s safety. This helps investors make informed decisions based on trustworthy information about a company's mineral resources.

The Eastern Expansion Drill Program Identified Several Mineralized Northwest Structures Hosting Shallow Mineralization Encountered Within a 1.2 Kilometre Trend

EASTERN EXPANSION PROGRAM HIGHLIGHTS:

• At least three mineralized northwest oriented structures have been identified within the 1.2 kilometre eastern expansion trend running parallel to the Pittsburg-Monarch fault that suggest a series of footwall fault splays as opposed to a singular east-west structure;
• TXC25-173 cut 0.92 metres of 2,122.7 grams per tonne (g/t) silver equivalent (AgEq) (1,162 g/t silver (Ag) & 8.79 g/t gold (Au)) from 220.9 metres, and a separate zone of 1.04 metres grading 534.8 g/t AgEq (189.8 g/t Ag & 3.16 g/t Au) from 215.5 metres;
• TXC25-178 drilled 6.4 metres of 296.6 g/t AgEq (135.7 g/t Ag & 1.47 g/t Au), including 0.46 metres of 3,853 g/t AgEq (1,771 g/t Ag & 19.06 g/t Au) from 183.8 metres in a north-south oriented structure within the M&I Conversion Area at DPB South; and
• Results from the Company's drill program targeting expansion potential across a one kilometre trend of vein corridor between the DPB and Northwest Step Out resource areas (the "Northwest Expansion Program") and the Eastern Expansion Program will be incorporated into an updated mineral resource estimate and preliminary economic assessment on Tonopah West estimated to be completed in February 2026.

Vancouver, British Columbia--(Newsfile Corp. - December 2, 2025) - Blackrock Silver Corp. (TSXV: BRC) (OTCQX: BKRRF) (FSE: AHZ0) ("Blackrock" or the "Company") announces the final results from its fully-funded eastern expansion drill program (the "Eastern Expansion Program" or the "Program") at its 100% owned Tonopah West project located in Nye and Esmeralda Counties, Nevada, United States ("Tonopah West").

The Eastern Expansion Program was a follow up to the Company's successful Scout drilling program completed at Tonopah West in February 2025 (see March 31, 2025 news) which shows additional upside for the shallow southern portion of the Denver-Paymaster and Bermuda-Merten vein groups ("DPB South") resource area (the "M&I Conversion Area") to expand the resource area 1,200 metres in an easterly direction (the "Eastern Expansion Zone").

The Company commenced the Eastern Expansion Program in July 2025 within the Eastern Expansion Zone, utilizing reverse circulation (RC) drilling with RC pre-collars to establish initial holes, which were then deepened using diamond core drilling (core tails) for more detailed geological analysis. The Program drilled a total of 6,798 metres (22,896 feet) in twenty-four drillholes, however, only 22 drillholes were completed, as two pre-collar holes were not usable for core tails. Of the 22 completed drillholes, three were core holes completed from surface.

Andrew Pollard, Blackrock's President and CEO, stated, "Whereas we set out to target a single east-west mineralized structure, drilling from our Eastern Expansion Program has defined at least three distinct, parallel mineralized zones oriented northwest. These structures appear to be splays off the Pittsburgh-Monarch fault system. Each of these zones has intersected shallow, high-grade, and thick mineralization, indicating significant potential for further expansion in the area. Additionally, drilling in the M&I Conversion Area at DPB South has successfully connected previously isolated intercepts, confirming the presence of north-south trending structures and suggesting additional tonnage potential. Work on our upcoming mineral resource estimate and preliminary economic assessment is now underway and on track for a targeted completion date in February 2026. These will incorporate data from both our Northwest and Eastern Expansion drill programs."

The Eastern Expansion Program encountered at least three northwest oriented structures which appear to be mineralized and offset the southern caldera margin to the northeast. The structures are parallel to the Pittsburg-Monarch fault and suggest a series of footwall fault splays associated with the main Pittsburg-Monarch fault. Figure 1 below shows the approximate location and orientation of the northwest fault system.

Drilling to date shows shallow, high-grade, and thick zones of mineralization in each of these structures and suggest increased expansion potential along this northwest structural corridor. Historically, the Pittsburg-Monarch fault was considered an ore control within the district with the thickest historically mined veins at Victor and Ohio abutting the main fault. The Company's drilling in the Eastern Expansion Zone has returned thick vein intervals of gold and silver along the parallel structures confirming the importance of the Pittsburg-Monarch and its footwall fault splays.

Two drillholes, TXC25-171 and TXC25-178, were drilled in the M&I Conversion Area. These drillholes were directed to the west to understand several north-south structures encountered in the previous drilling. The Program was successful in capturing high-grade drill intervals from the north-south structures and shows there are multiple mineralized structures with similar orientation in the 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 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 into AAL's system. The 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.

This news release contains "forward-looking statements" and "forward-looking information" (collectively, "forward-looking statements") within the meaning of Canadian and United States securities legislation, including the United States Private Securities Litigation Reform Act of 1995. All statements, 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 strategic plans; the anticipated objectives and results from the Company's drill programs at Tonopah West; the timing of completion of an updated mineral resource estimate and preliminary economic assessment on Tonopah West; the Company's de-risking initiatives at Tonopah West; estimates of mineral resource quantities and qualities; estimates of mineralization from drilling; geological information projected from sampling results; and the potential quantities and grades of the target zones.

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, uncertainties and other factors that may cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements contained in this news release and the Company has made assumptions and estimates based on or related to many of these factors. Such 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 historical data; general market and industry conditions; and those factors identified under the caption "Risks Factors" in the Company's most recent Annual Information Form.

Forward-looking statements are based on the expectations and opinions of the Company's management on the date the statements are made. The assumptions used in the preparation of such statements, although considered reasonable at the time of preparation, may prove to be imprecise and, as such, readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date the statements were made.
