Table 1: Tonopah West Drillhole Assays above 190 gpt AgEq

 

Drillholes TXC24-087, -090, -091, -100 and TXC24-101 define a new high-grade gold and silver chute that has a direction of azimuth 320° to 330° and a pitch of 32° along the Merton/Bermuda high-grade vein system. The length of the high-grade ore chute is approximately 175 metres but open to the NW and SE. TXC24-092 is the start of another high-grade chute suggesting periodicity of the high-grade gold and silver along the strike of the vein system. The high-grade appears to have a 105 metres cyclicity. More work is required to understand the high-grade chutes, orientation and periodicity.

Drillholes showing NVACO in Table 1 are mineralized; however, silver equivalent values are less than the 190 AgEq cut off. Veins identified in these drillholes show the vein are mineralized with lower grade gold and silver. Gold values range from 0.096 g/t to 0.734 g/t Au and silver values range from 4.2 g/t to 37.7 g/t Ag and AgEq between 7.8 and 134.4 g/t AgEq. These values assist with modelling the veins and their orientation and geometries.

TXC24-079, -089 and 090 encountered voids in the drilling. The voids are the result of fault fractures and potentially old workings. The cavities were between 2 to 6 metres in width. The larger cavity caused TXC24-090 to be terminated prematurely.

The drill program is completing 2 to 3 core tails per week with lab turn around at roughly 6 to 8 weeks, with 30 drillholes completed to date. Many drillholes have pending assays which will be released as batches through the fall and winter months.

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 sheets are delivered to AAL personnel who organize and process the sample intervals pursuant to the Company's instructions.

All core is cut using core saws at AAL's facility according to the Company's instructions delivered with each core hole. The RC and core samples, and QA/QC samples are crushed and pulverized, 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 blanks, lab blanks or a certified reference material approximately every 15th to 20th sample.

Cautionary Note Regarding Forward-Looking Statements and Information

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 timing of completion of the Company's drill program at Tonopah West and the anticipated objectives and results therefrom; the Company's objective to connect the DPB and NW step-out areas; 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.
