The NW Step Out program extended high-grade silver and gold mineralization an additional 600 metres to the northwest, identifying a new intrusive complex as a priority exploration target. Key intercepts include 0.49 metres of 1,096.0 g/t AgEq and 0.43 metres of 1,114.4 g/t AgEq, with detailed QA/QC procedures and metal equivalent assumptions disclosed. However, the intercepts are generally narrow, and true widths are not provided for individual results. Reasoning: Blackrock Silver's drill program successfully extended high-grade silver-gold mineralization 600 meters to the northwest at Tonopah West and identified a new intrusive target, demonstrating significant exploration success, though the intercepts are narrow and true widths are not specified for each. - Positive factor: High-grade silver and gold intercepts, including bonanza grades, were reported. - Positive factor: The NW Step Out Program successfully extended mineralization an additional 600 metres to the northwest. - Positive factor: A new intrusive complex has been identified as a priority exploration target for silver and gold concentration. - Positive factor: QA/QC procedures are detailed, and a Qualified Person has approved the release. - Positive factor: Metal equivalent assumptions are clearly disclosed. - Negative factor: Most reported intercepts are narrow, which can impact overall resource potential. - Negative factor: True widths are not provided for individual intercepts, only a general range for the modelled vein geometries. - Negative factor: The Eastern Expansion Program has encountered challenges with faulting, requiring further geological diligence. - Negative factor: Elevated arsenic and antimony were noted in one drillhole, indicating potential deleterious elements. Facts used in scoring: 38 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Several intercepts, such as 1,114.4 g/t AgEq over 0.43 m and 1,096.0 g/t AgEq over 0.49 m, are exceptionally high-grade, well above the typical thresholds for silver and gold in epithermal deposits. Evidence · table > 1,114.40 Context: 0.43 **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The document states that 'True thickness is 40 to 65% of interval thickness based on the modelled vein geometries' but does not provide specific true widths for individual intercepts, implying that reported lengths are downhole widths. Evidence · text > True thickness is 40 to 65% of interval thickness based on the modelled vein geometries **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The 'NW Step Out Program' explicitly aimed to and succeeded in extending mineralization 'an additional 600 metres northwest along the projection of the Denver vein system'. Evidence · text > The NW Stepout Drill Program Extends Mineralization Another 600 Metres to the Northwest Along the Projection of the Denver Vein System **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release includes a detailed 'Quality Assurance/ Quality Control' section outlining sampling procedures, laboratory analysis, and the insertion of blanks and certified reference materials. Evidence · text > 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. **Compositing Transparent** Polarity: positive Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals. Why it applies: The document clearly states the cut-off grade used for reporting significant results: 'using a 100 g/t AgEq Cut-off Grade'. Evidence · text > using a 100 g/t AgEq Cut-off Grade **Deleterious Elements Present** Polarity: negative Definition: Penalty elements \(arsenic, antimony, etc.\) or refractory concerns noted in the release. Why it applies: Drillhole TXC26-190 intersected altered limestones 'carrying elevated gold, arsenic and antimony at the volcanic contact'. Evidence · text > It bottomed at 1,383 metres in altered Palmetto Group limestones carrying elevated gold, arsenic and antimony at the volcanic contact. **Epithermal Deposit** Polarity: neutral Story-specific tag Definition: No canonical definition is currently available. Why it applies: The company context at the bottom of the document describes the project as 'low-sulphidation epithermal gold & silver projects'. Evidence · text > low-sulphidation epithermal gold & silver projects ## Extracted facts Stored fact records: 38.

Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
