Sandfire Resources LtdS
Sandfire Resources Ltd (ASX: SFR) is a Perth-headquartered copper producer whose original flagship, the high-grade DeGrussa copper-gold mine (Western Australia, commercial production from 2012), ceased mining in Oct 2022 after producing over 650,000 tonnes of copper and 380,000 ounces of gold over its life -- it is now in care and maintenance, with asset divestment underway (the Old Highway Gold Project sold in FY25; the DeGrussa processing plant sold Apr 2025 for reuse elsewhere). Sandfire's current production comes from two assets acquired/built since: MATSA (acquired from Trafigura/Mubadala for US$1.865 billion, completed 1 Feb 2022), a long-established underground copper-zinc-lead-silver polymetallic complex in Spain's Iberian Pyrite Belt comprising three mines and a central processing facility (2025 Ore Reserve: 38.3Mt at 1.5% Cu, 2.6% Zn, 0.8% Pb, 37.3g/t Ag, containing 588kt copper/1,003kt zinc/315kt lead/45.9Moz silver) -- MATSA generates roughly 65-70% of group copper-equivalent production; and Motheo (Kalahari Copper Belt, Botswana), an open-pit mine wholly built by Sandfire itself (final investment decision Dec 2020, mining licence granted Jul 2021, first concentrate 25 May 2023, commercial production declared Jul 2023, officially opened Aug 2023) with an initial base-case mine life of 12.5 years (2025 Ore Reserve, as at 30 Jun 2024: 45.7Mt at 0.9% Cu, 13.5g/t Ag, containing 427kt copper/19.8Moz silver). Sandfire is targeting extending Motheo's life to a minimum 15 years within five years through ongoing exploration across its wider Kalahari Copperbelt landholding, and in Feb 2026 executed definitive agreements with Havilah Resources to advance the Kalkaroo Copper-Gold Project in South Australia as a further growth option.
Lifecycle Milestones
Construction Milestones
5 of 5 reached- Jul 2021 · The Government of Botswana granted Sandfire the mining licence for Motheo on 7 Jul 2021 -- the final major permitting milestone required to enable full-scale construction (the Botswana government separately holds a right, not yet exercised as of this pass, to acquire up to a 15% interest in the T3-Motheo Project). Full-date precision, primary-announcement sourced (globalminingreview.com / kitco.com, both reporting the same 7 Jul 2021 announcement). · Source
- Dec 2020 · Sandfire's board took the final investment decision on the ~US$259-279M Motheo development in Dec 2020 (see technicalReportNote for the unreconciled two-figure capex range). Month precision only (exact day not independently confirmed this pass). · Source
- Reached — date not disclosed · Initial site works at Motheo (sterilisation drilling, a 15km access road, a 200-person camp) were already 'well advanced' by the time the Jul 2021 mining licence was granted (per the same licence-announcement coverage), meaning genuine construction activity began in H1 2021, ahead of the licence that enabled full-scale construction -- a real, not erroneous, ordering (early site-preparation work under a lesser permit before the main mining licence is a normal project-development sequence). Dated to 1 Jan 2021 as a year-precision placeholder (no more precise start date found this pass); do not read the day/month as confirmed. [Task #697 chronology ruling, 2026-08-25] achievedDate cleared (was 2021-01-01). Task #696's permit rule flagged this row as predating the 7 Jul 2021 Motheo mining licence. The row's own note had already anticipated the objection from both directions -- it recorded the value as "a year-precision placeholder (no more precise start date found this pass); do not read the day/month as confirmed", and separately established that initial site works (sterilisation drilling, a 15km access road, a 200-person camp) were genuinely "well advanced" before the licence was granted, which is a normal sequence rather than an error. So there are two claims here and only one of them is sound: the ORDERING is real and stays in the note, but the DATE was an explicit placeholder that no source supports, and a placeholder should not be the thing a consistency rule adjudicates. Cleared per the house convention for imprecise dates; the H1 2021 finding and its citation are preserved above. This leaves the ticker's remaining PERMIT_GRANTED_AFTER_CONSTRUCTION_DECISION pair, already covered by the permit rule's conditional-FID expectedGap. Note that this row is the precedent HGO's CONSTRUCTION_START note cites (Task #622) for early works preceding formal sign-off -- that precedent is unaffected, since it rests on the sequence, not on the placeholder date. · 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.

ouncesFound is deliberately left null per this repo's still-open Task #324 ouncesFound/copper-unit policy question, same convention as this backlog's other copper majors (FM/CCO/HBM/LUN, Task #619/#620). mineLifeYears (12.5 years) is Motheo-specific, from Sandfire's own Dec 2020 final-investment-decision DFS -- the newer, wholly Sandfire-built asset with a clean company-published figure; MATSA (acquired already-operating in 2022, a multi-decade-old asset under prior owners) has an Ore Reserve tonnage/grade on file above but no standalone company-published mine-life-years figure was found this pass. initialCapexUsd for Motheo carries a genuine, unreconciled source conflict (miningweekly.com states a US$259 million restart capital cost; a separate nsenergybusiness.com source states US$279 million for the same project) -- left as a CHECKED, unwritten gap rather than silently picking one figure over the other, consistent with this backlog's standing practice for real source disagreements (see FM's debtUsd note, Task #620).
