# Northern Star doubles Pogo mine resources Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/northern-star-doubles-pogo-mine-resources--24928056-50a1-474d-80c7-f45cf877682a Original source: https://www.miningnewsnorth.com/story/2026/06/05/news-nuggets/northern-star-doubles-pogo-mine-resources/9705.html Publisher: miningnewsnorth Original announcement: 2026-07-29T00:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-18T21:23:04.025Z Atlas analysis updated: 2026-09-18T21:23:04.025Z - Company: Northern Star Resources Ltd. - Ticker: Unavailable - Exchange: Unavailable - Region: Alaska - Primary commodity: Gold - Secondary commodities: None reported - Document categories: Resource update, Production - Extracted: 2026-09-18 21:23:04 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Northern Star Resources has reported a massive expansion of the Pogo mine resources in Alaska, with total resources doubling to 37.96 Mt at 7.6 g/t gold. The update includes a maiden resource for the Star deposit and significant growth in proven and probable reserves to 2.39 million ounces. Reasoning: Substantial expansion of both reserves and resources driven by new deposits \(Star\) and higher gold prices/lower cut-off. - Positive factor: Significant tonnage growth \(>100%\) - Positive factor: Contained gold increase \(~51%\) - Positive factor: Maiden resource for Star deposit - Positive factor: Reserve growth \(>10%\) - Negative factor: Management transition \(CEO stepping down\) Facts used in scoring: 6 ## Classification and evidence **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. Why it applies: The Star deposit is reported as an inaugural resource estimate. Evidence · text > including a maiden resource estimate for the Star deposit **Tonnage Growth** Polarity: positive Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved. Why it applies: Total resource tonnage increased by more than 100% compared to a year ago. Evidence · text > This marks a more than 100% increase in tonnage **Contained Metal Growth** Polarity: positive Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes. Why it applies: Contained gold increased by approximately 51% compared to the previous year. Evidence · text > a roughly 51% increase in contained gold ## Extracted facts Stored fact records: 6.
