Metallic Screen and Duplicate Re-Assays
Metallic screen assays and duplicate re-assays were run on selected intervals from the spring 2023 RC drilling campaign, where visible gold was identified, in order to assess the potential for coarse gold that is not adequately represented in standard 30-gram fire assay analyses. The results are tabulated herein and show the high-grade intervals clearly have “coarse” gold present in the plus 100-mesh size fraction used in the analyses. This coarse gold fraction tends to be under-represented in a standard 30-gram sample preparation for fire assay. The highest grade samples show the largest amount of “coarse’ gold relative to the lower grade samples, for which the presence of particulate gold does not appear to be an issue. Generally, the results show a dramatic grade increase for samples with initial grades of +4-5 grammes per tonne (“gpt”) gold, although that is not always the case.
The highest grade sample in drill hole PRC23-97, which originally contained a grade of 51 gpt gold, returned a grade of 72.5 gpt gold in metallic screen analyses, a 42% increase in grade. For that sample grades of 65 and 74.8 gpt gold were also returned upon re-assaying the original sample using a larger (50-gram) pulp size. The results of metallic screen analyses and re-assaying using a larger pulp compare very favorably with one another. This suggests re-assaying by the metallic screen procedure of +4 gpt gold internals is recommended. Metallic screen analyses are recommended also when discrepancies exist in standard assay and re-assay sampling.
Overall the metallic screen analysis and re-assaying exercise of the sample selected resulted in a 25.9% increase in average grade of the sample suite. Metallic screen analyses and re-assaying of low-grade samples returns grade discrepancies of generally less than 0.5 gpt gold, and mostly less than 0.1 gpt gold, suggesting coarse gold is not an issue in the lower grade samples submitted for metallic screen analyses.

Forward-looking statements in this news release include statements in relation to the timing, cost and other aspects of the 2023 exploration program; the potential for development of the mineral resources; the potential mineralization and geological merits of the exploration properties; and other future plans, objectives or expectations of the Company. There can be no assurance that such statements will prove to be accurate and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause actual results to differ materially from the Company's plans or expectations include the risk that actual results of current and planned exploration activities, including the results of the Company's 2023 drilling program(s) on its properties, will not be consistent with the Company's expectations; the geology, grade and continuity of any mineral deposits and the risk of unexpected variations in mineral resources, grade and/or recovery rates; fluctuating metals prices; possibility of accidents, equipment breakdowns and delays during exploration; exploration cost overruns or unanticipated costs and expenses; uncertainties involved in the interpretation of drilling results and geological tests; availability of capital and financing required to continue the Company's future exploration programs and preparation of geological reports and studies; delays in the preparation of geological reports and studies; the metallurgical characteristics of mineralization contained within the exploration properties are yet to be fully determined; general economic, market or business conditions; competition and loss of key employees; regulatory changes and restrictions including in relation to required permits for exploration activities (including drilling permits) and environmental liability; timeliness of government or regulatory approvals; and other risks detailed herein and from time to time in the filings made by the Company with securities regulators. In connection with the forward-looking information contained in this news release, the Company has made numerous assumptions, including that the Company's 2023 programs would proceed as planned and within budget.
