# Major gold and industrial mineral sands resource defined at Grinder deposit, Icy Cape district, Alaska Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/major-gold-and-industrial-mineral-sands-resource-defined-at-grinder-deposit-icy--68392731-6508-4504-8333-8090b0c4229a Original source: https://www.mining-journal.com/partners/partner-content/4537153/major-gold-industrial-mineral-sands-resource-defined-grinder-deposit-icy-cape-district-alaska Publisher: miningjournal Original announcement: 2026-10-01T09:31:21.028Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-01T09:33:13.838Z Atlas analysis updated: 2026-10-01T09:33:13.838Z - Company: Alaska Mental Health Trust Land Office - Ticker: Unavailable - Exchange: Unavailable - Region: Alaska - Primary commodity: Gold - Secondary commodities: Garnet, Zirconium, Titanium - Document categories: Resource update, Other - Extracted: 2026-10-01 09:33:14 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary The Alaska Mental Health Trust Land Office has defined a NI 43-101 compliant indicated resource at the Grinder deposit, featuring 1.126 Moz of gold and 350,950 Mt of garnet. The deposit is hosted in 34.1 Mt of marine sediment and represents a significant placer gold and mineral sands system in the Icy Cape district. Reasoning: The announcement defines a major multi-commodity resource \(gold and garnet\) with high tonnage and significant scale for the region. - Positive factor: Large gold endowment \(1.126 Moz\) - Positive factor: Significant industrial garnet resource \(350,950 Mt\) - Positive factor: NI 43-101 compliant resource estimate - Positive factor: Secure tenure via TLO ownership - Positive factor: District-scale potential with 30km of mineralised trends Facts used in scoring: 2 ## Classification and evidence **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The resource estimate is explicitly stated as NI 43-101 compliant. Evidence · text > A newly completed NI43‑101 compliant resource estimate **Indicated Resource** Polarity: positive Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves. Why it applies: The resource is classified as indicated. Evidence · text > outlines an indicated resource of 1.126Moz of gold ## Extracted facts Stored fact records: 2.

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.
