Northern Star Resources Ltd
Northern Star Resources is a large ASX-listed multi-site gold producer operating three production hubs -- KCGM (the historic Kalgoorlie "Super Pit", WA), Yandal (WA), and Pogo (Alaska, USA) -- plus the Hemi development project (Pilbara, WA), acquired via the May 2025 Scheme of Arrangement acquisition of De Grey Mining. FY26 (year ended 30 June 2026) gold sold was 1,543koz across the three producing hubs (Yandal 434koz vs >420koz guidance, Pogo 265koz vs >250koz guidance), at a group AISC of A$2,698/oz. The company ended FY26 with unaudited cash and bullion of A$1,255M and no corporate bank debt, while continuing an A$500M on-market share buyback. KCGM's Fimiston Mill Expansion (A$1.5B, capacity 13Mtpa to 27-37Mtpa) remains under construction, targeting commissioning in early FY27. Group Mineral Resources grew 26% to 88.9Moz and Ore Reserves 27% to 28.4Moz as at 31 March 2026 (up from 70.7Moz/22.3Moz a year earlier), the increase driven substantially by Hemi's first inclusion in the group resource statement (11.2Moz resources / 6.0Moz reserves). Hemi's timeline has slipped -- a Final Investment Decision remains pending (subject to environmental approvals and project debt financing) and FY26 capex on Hemi (A$104M) came in well below the A$165-175M guided, pushing expected first production toward 2027. Stuart Tonkin remains Managing Director and CEO; a leadership transition is underway, with Glencore executive Suresh Vadnagra named as incoming CEO effective 5 Oct 2026 (not yet started as of this record) and CFO Ryan Gurner appointed deputy CEO to bridge the interim period. Chairman Michael Chaney is also expected to be succeeded by Michael Ashforth.
Lifecycle Milestones
Construction Milestones
5 of 5 reached- Reached — date not disclosed · KCGM's Fimiston Open Pit ("Super Pit") has been in continuous production since 1989 under a series of owners predating Northern Star's current form; no single confirmed permit date was found to a primary source this pass. · Source
- Reached — date not disclosed · Same caveat as PERMIT_GRANTED -- multi-decade, multi-owner asset with no single company-wide construction-decision date. · Source
- Jan 1989 · Anchored to the Fimiston Open Pit's creation in 1989 by the original Kalgoorlie Consolidated Gold Mines JV (Homestake Gold of Australia / Gold Mines of Kalgoorlie), predating Northern Star's ownership -- the best-documented construction event for the flagship asset. · Source
- Jan 1989 · Same 1989 anchor -- the Golden Mile/Super Pit has produced continuously since. Current production status is directly evidenced by FY26 group gold sold of 1,543koz across KCGM, Yandal, and Pogo. · Source
- Reached — date not disclosed · Genuinely reached, but no single company-wide commercial-production date exists across a multi-mine Australian/US portfolio (Kalgoorlie Consolidated Gold Mines/KCGM, Jundee, Pogo in Alaska, plus the newly-acquired Hemi Project) assembled via mergers and acquisitions over more than a decade. FY2026 (year ended 30 June 2026) results reported 1.543 million ounces of gold sales at AISC of A$2,698/oz across three production centres, generating ~A$1.2 billion net mine cash flow. This row was missing entirely prior to 2026-08-21 -- a genuine data gap, not a stage error; Miner.stage was already correctly PRODUCTION. · Source
Milestones are recorded only from a company's own dated disclosure. A milestone with no date shown is one we can confirm was reached but for which no date was disclosed — we don't estimate one. "Not yet reached" means exactly that, not that a date is missing. An "Expected" line likewise only ever reflects the company's own guidance (e.g. a study or permit decision targeted for a stated quarter) — most not-yet-reached milestones have none, and that absence means no such guidance has been disclosed, not that one is overdue.

A relative ranking of how closely this company matches the profile of juniors that have actually been acquired — not a probability, and not a reason to buy. Acquisitions are rare: only a few dozen significant deals happen a year across a universe of thousands of juniors, so even a high score here describes a long shot. The strongest signal the underlying research identifies — whether a major already holds a JV, earn-in, or 5–19.9% strategic stake — isn't tracked yet and is absent from this score.
