The program identified a new intrusive complex as a priority exploration target and returned several bonanza-grade intercepts, including 0.49 m of 1,096.0 g/t AgEq and 0.43 m of 1,114.4 g/t AgEq. Drilling is ongoing with additional assays pending. Reasoning: Blackrock Silver's drill program successfully extended high-grade silver-gold mineralization by 600 metres to the northwest at Tonopah West, identifying a new intrusive target with several bonanza-grade intercepts, significantly expanding the project's potential. - Positive factor: Significant 600-metre extension of high-grade silver-gold mineralization to the northwest. - Positive factor: Identification of a new intrusive complex as a priority exploration target for concentrated mineralization. - Positive factor: Multiple bonanza-grade intercepts, including 0.49 m of 1,096.0 g/t AgEq and 0.43 m of 1,114.4 g/t AgEq. - Positive factor: Comprehensive QA/QC procedures disclosed, including certified lab and QP sign-off. - Positive factor: Compositing parameters \(100 g/t AgEq cut-off\) and metal equivalent assumptions are transparently disclosed. - Negative factor: Reported intercept lengths are apparent \(downhole\) widths, with true thickness only estimated as a range \(40-65%\). - Negative factor: Deleterious elements \(arsenic and antimony\) were noted in one drillhole \(TXC26-190\), indicating potential processing considerations. Facts used in scoring: 40 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The NW Step Out Program drilling extended the inner mineralized high-grade corridor an additional 600 metres northwest along the projection of the Denver vein system. Evidence · text > 600-metre northwest extension: NW Step Out Program drilling extends the inner mineralized high-grade corridor an additional 600 metres 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 dedicated 'Quality Assurance/ Quality Control' section detailing sampling, laboratory procedures \(American Assay Laboratory\), and internal checks \(blanks, standards, certified reference material\). 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. 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. **Compositing Transparent** Polarity: positive Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals. Why it applies: The cut-off grade of 100 grams per tonne silver equivalent used for reporting significant results is clearly stated. Evidence · text > Table 1 summarizes the significant results of the Eastern Expansion Program and NW Step Out Program using a cut-off grade of 100 grams per tonne silver equivalent. **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', indicating that individual true widths are not explicitly provided for each intercept. Evidence · text > True thickness is 40 to 65% of interval thickness based on the modelled vein geometries **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. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The Eastern Expansion Program drilling is described as adding to the resource area, which is characteristic of infill drilling to expand beyond the existing mineral resource. Evidence · text > Eastern Expansion Program drilling adds to the resource area: Drilling at DPB South returned high-grade silver and gold between the Pittsburg-Monarch and McKane fault systems, expanding beyond the March 2026 mineral resource. **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Intercept TXC26-200 returned 0.49 m of 1,096.0 g/t AgEq, which is well above the exceptional threshold for gold equivalent grades in epithermal deposits. Evidence · table > 1,096.00 Context: 0.49 **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Intercept TXC26-192A returned 0.43 m of 1,114.4 g/t AgEq, which is well above the exceptional threshold for gold equivalent grades in epithermal deposits. Evidence · table > 1,114.40 Context: 0.43 **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Intercept TXC26-184 returned 0.76 m of 1,036.6 g/t AgEq, which is well above the exceptional threshold for gold equivalent grades in epithermal deposits.

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.
