The results from the Program to date show that the Merten-Bermuda vein group in the DPB South area are exceeding the Company's expectations, confirming high-grade silver and gold connects across significant lengths at higher-than-average grades.

Andrew Pollard, the Company's President and Chief Executive Officer, stated: "We continue to be impressed by the results from our ongoing and expanded M&I Conversion Program, that collectively with previous results, validate our model and showcase a remarkable continuity of high-grade mineralization during the early years of anticipated production. We expect to complete this aspect of our 2025 drilling by April and incorporate the results into a resource update over the summer. Assays are eagerly anticipated for 5 RC scout holes, with 3 additional core holes already in the works, that are testing what we see as significant expansion potential to the east of the M&I Conversion Area where a high-angle structural zone is emerging."

The geometry of the high-grade silver and gold is sizable with high-grade chutes plunging to the northwest with an area exceeding 175 by 350 metres and open down plunge. The high-grade chutes have thicker vein intercepts along the axis of the chute ranging from 2 metres to over 5 metres.

A secondary mineralized chute has emerged to the east along a west-northwest, high-angle structural zone with high grade silver and gold. Figure 1 shows the size of the high-grade M&I Conversion Area and the emerging eastern target. A series of five RC drillholes have been completed and three core holes are planned to better define the size and grade of this mineralized chute.

All drillholes returned significant silver and gold assays with the exception of TXC24-120. As is evident from Table 1, the high-grade results are associated with thicker intercepts of quartz vein material. This combination of high grade and thickness should have a positive impact on the proposed development of the DPB South 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.

Forward-looking statements in this news release relate to, among other things: the Company's strategic plans; the timing of completion of the Company's drill program at Tonopah West and the anticipated objectives and results therefrom; the incorporation of the results from the M&I Conversion Program in an updated mineral resource estimate on Tonopah West and the anticipated timing of release thereof; 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.
