These Programs Support the Advancement of Tonopah West Towards the Permitting of an Exploration Decline to Enable Test Mining and the Extraction of a Bulk Sample
HIGHLIGHTS:
- The Phase 2 hydrology program will consist of placing 5 additional piezometers, a dewatering well and a groundwater monitoring well;
- Geotechnical evaluation is progressing on 22 drillholes along the proposed decline alignment; and
- A seismic program consisting of 18 kilometres in seven lines is planned over the Tonopah West deposit and to the northwest to identify extensions and structural controls.
Blackrock Silver Corp. (TSXV: BRC,OTC:BKRRF) (OTCQX: BKRRF) (FSE: AHZ0) (‘Blackrock’ or the ‘Company’) is pleased to announce certain advancement programs (the ‘Programs’) at the Company’s 100% owned Tonopah West (‘Tonopah West’) project located in Nye and Esmeralda Counties, Nevada, USA. The Programs will consist of a Phase 2 hydrology program, geotechnical evaluation of the proposed decline alignment and a seismic survey intended to understand the structural controls and advance Tonopah West toward completing an exploration decline that will allow for test mining and the extraction of a bulk sample for metallurgical processing.
Andrew Pollard, the Company’s President and Chief Executive Officer, stated: ‘Tonopah West is moving forward on multiple fronts as we work to grow, optimize and de-risk the project toward underground development. The integration of hydrologic, geotechnical and seismic data from these Programs represents key de-risking initiatives, helping us refine engineering models, optimize decline design and establish a strong technical foundation for permitting our initial test mine and bulk sample area. These Programs are running in parallel as we await pending assay results and the delivery of an updated preliminary economic assessment on Tonopah West, currently slated for Q1 2026.’
Hydrology Programs
Montgomery and Associates was contracted to complete the hydrology programs on Tonopah West. In the Phase-1 hydrology program, the Company set four piezometers along the proposed alignment of the decline that have been collecting data that reports where water is present (see May 15, 2025 news release). Based on the information collected from the Phase-1 hydrology program, a Phase-2 hydrology program at Tonopah West has been approved. The Phase-2 program will be entirely within DPB South area of Tonopah West where the Company is planning its exploration decline, test mining and bulk sampling programs. The Phase-2 hydrology program will set five additional piezometers, a dewatering well and a groundwater monitoring well. Data from this infrastructure will help with engineering design of the decline, water pumping requirements and site disposal strategies.
Geotechnical Evaluations
Call & Nicholas, Inc. have been retained to complete geotechnical evaluations on Tonopah West. Detailed geotechnical evaluation on the Phase-1 piezometer holes has been completed. This evaluation is critical for the engineering and design of the proposed exploration decline. An additional 17 drillholes are being geotechnically logged and 36 samples have been collected for geotechnical unconfined compression strength testing. Approximately 59,000 metres (193,570 feet) of core drilling from the project has been evaluated for recovery and Rock Quality Designation (RQD). Additional geotechnical study is being planned.
Seismic Survey
The Company has contracted Bird Seismic Services, Inc. to complete 18 kilometres of 2D seismic data. The seismic data will be collected on seven lines cris-crossing the Tonopah West project area (See Figure 1.). Several lines have been located on the northwestern portion of Tonopah West to identify the extension of the Fraction caldera margin under cover. The goal of the seismic survey program is to better understand the structural controls of the deposit and identify extensions of silver and gold for drill targeting.

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 contents and completion of the Company’s Programs at Tonopah West and the anticipated objectives and results therefrom; the permitting of an exploration decline to enable test mining and the extraction of a bulk sample at Tonopah West; the timing of completion of an updated 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.
