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 factors
- Probable reserves established
- Significant contained tungsten trioxide
- PFS completed
Negative factors
- Low tungsten grade (0.17% WO3)
Facts used in scoring: 3
Classification and evidence
Probable Reservepositive
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-Supportingneutral
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”

Probable Reservepositive
Indicated Resource with demonstrated economic viability after applying modifying factors.
Why it applies: category is "probable"
Cut-off Undisclosednegative
High-grade interval reported without stating the cut-off grade used for compositing.
Why it applies: no cutoff_grade was stated
No QP/CP Disclosurenegative
No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience.
Why it applies: no Qualified or Competent Person is named anywhere in the release
PFS-Supportingneutral
Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component.
Why it applies: the release names the study this estimate supports
DFS-Supportingneutral
Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence.

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
