Intercepts include bonanza grades such as 4,074 g/t silver over 1.8 meters and 43.00 g/t gold over 1.5 meters, extending known high-grade mineralization and identifying a potential new high-grade gold system. These results reinforce the potential for a high-grade underground mine at the project. Reasoning: The drill results from Vortex and Brimstone systems at the Hycroft Mine show exceptionally high-grade silver and gold intercepts over significant widths, extending known mineralization and indicating potential for a new high-grade gold system, which strongly supports the potential for an underground mine. - Positive factor: Exceptional high-grade silver and gold intercepts - Positive factor: Extension of known high-grade mineralization - Positive factor: Identification of potential new high-grade gold system - Positive factor: Thick, continuous mineralization - Positive factor: Qualified Person sign-off Low confidence — this extraction should be reviewed alongside the original source.

Evidence · table > 4,074.00 Context: 1.8 **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The release states that H26D-6167A was designed to 'test and extend high-grade mineralization to the north' at Brimstone. Evidence · text > Hole H26D-6167A was designed to test and extend high-grade mineralization to the north. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The CEO comments that the company is 'extending it and are consistently intersecting thick, continuous, high-grade mineralization' for the high-grade silver system. Evidence · text > We're not just confirming the high-grade silver system, we're extending it and are consistently intersecting thick, continuous, high-grade mineralization. **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 news release states that a Qualified Person has reviewed and approved the scientific and technical information. Evidence · text > The Company's Qualified Person for exploration is Alex Davidson, Vice President, Exploration, who has reviewed and approved the scientific and technical information contained in this news release. **Metal Equivalent Opaque** Polarity: negative Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Why it applies: Metal equivalent grades are reported with price assumptions \($3,600/oz gold and $48/oz silver\) but without disclosing recovery or payability assumptions. Evidence · text > $3,600/oz gold and $48/oz silver are used for gold equivalent \(AuEQ\) and silver equivalent \(AgEQ\) numbers **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 reported intervals are given as downhole widths, and no true width or drill orientation information is provided in the document. Evidence · text > 30.5 meters at 780.53 g/t silver **Heap Leach Route** Polarity: neutral Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected. Why it applies: the document describes a heap\_leach route \("heap leach"\) **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a mill\_cil route \("CIP"\) ## Extracted facts Stored fact records: 48.

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.
