# Pilot Mountain Tungsten Project, US Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/pilot-mountain-tungsten-project-us--74c2a8fe-e57f-4312-b007-02effe0f5faa Original source: https://www.mining-technology.com/projects/pilot-mountain-tungsten-project-us/ Publisher: miningtechnology Original announcement: 2026-10-08T04:45:44.532Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-08T04:46:46.404Z Atlas analysis updated: 2026-10-08T04:46:46.404Z - Company: Guardian Metal Resources - Ticker: Unavailable - Exchange: Unavailable - Region: Nevada, US - Primary commodity: Tungsten - Secondary commodities: Silver, Zinc - Document categories: Resource update - Extracted: 2026-10-08 04:46:47 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Guardian Metal Resources has reported probable mineral reserves for the Pilot Mountain tungsten project in Nevada, estimated at 11.82 million tonnes. The reserves grade 0.17% tungsten trioxide, 9.28 g/t silver, and 0.28% zinc, supported by a completed Pre-Feasibility Study. Reasoning: The document reports probable mineral reserves from a completed Pre-Feasibility Study \(PFS\) with significant contained metal scale. - Positive factor: Probable reserves established - Positive factor: Significant contained tungsten trioxide - Positive factor: PFS completed - Negative factor: Low tungsten grade \(0.17% WO3\) Facts used in scoring: 3 ## Classification and evidence **Probable Reserve** Polarity: positive Definition: Indicated Resource with demonstrated economic viability after applying modifying factors. Why it applies: The document explicitly states probable mineral reserves of 11.82mt. Evidence · text > The probable mineral reserves at the Pilot Mountain tungsten project are estimated to be 11.82 million tonnes \(mt\) **PFS-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component. Why it applies: The reserves are part of a completed Pre-Feasibility Study \(PFS\). Evidence · text > A pre-feasibility study \(PFS\) for the project was completed in June 2026 ## Extracted facts Stored fact records: 3.

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.
