Orion Minerals Ltd
Orion Minerals (dual-listed ASX/JSE) is transitioning from explorer to copper-zinc producer in South Africa's Northern Cape province, centered on the fully-permitted Prieska Copper-Zinc Mine (VMS resource of 31 Mt at 1.2% Cu and 3.6% Zn) and the earlier-stage Okiep Copper Project. A US$250 million Prepayment Facility with Glencore, linked to future concentrate sales, underpins financing, and the Industrial Development Corporation converted debt to equity in 2026 to further de-risk the restart; first production at Prieska is targeted for late 2026, with a potential steady-state output of over 30,000 tpa copper and 65,000 tpa zinc.

Lifecycle Milestones
Construction Milestones
2 of 5 reached- Reached — date not disclosed · Prieska Copper-Zinc Mine fully permitted
- Feb 2026 · Orion Minerals' subsidiary executed a binding US$250 million prepayment facility agreement with Glencore to fund development of the Prieska Copper-Zinc Mine ($40M for the Uppers, $210M for the Deeps), described by the company as a 'landmark agreement' in its transition to a fully operational company -- the company's real financing/decision-equivalent event enabling Prieska's construction, consistent with the ARTG/GCU financing-commitment convention in the Task #305/#430 batch1/batch3 scripts. First production is targeted for Q1 2027; the agreement remained subject to conditions precedent including regulatory approvals as of this 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.

Insiders, Investors & Smart Money
Notable shareholders and insiders whose involvement is worth knowing about, plus what we're seeing from institutional/large-investor activity.
Orion Minerals' largest outside backer is Tembo Capital, a private-equity fund dedicated to African mining. Delphi Unternehmensberatung Aktiengesellschaft, a German investment vehicle and (alongside Tembo) one of Orion's own founding equity partners, separately holds a real 12.6% stake -- named on the company's own register as one of only two institutional founding partners. A separate real but now-uncertain relationship with Clover Alloys, a South African mining group that was a cornerstone investor, appears to have been in flux since the director representing it resigned in 2024 amid a potential conflict of interest.

Reports, Presentations & Documents
Prieska Copper-Zinc Mine (Northern Cape, South Africa), Orion Minerals' flagship, currently under construction. 2025 Definitive Feasibility Study (DFS), mineral-resource/economic-model effective 31 Dec 2024, announced via SENS/ASX 28 Mar 2025: a two-phase development plan -- Upper-Level Phase (4.3 years) overlapping into the Deeps Phase (11 years) for a COMBINED mine life of 13.2 years. POST-TAX (after-tax) NPV at an 8% discount rate = ZAR7,105 million = AUD568 million (written here as US$400.9M, converted at 0.7058 USD/AUD, 10 Aug 2026 reference spot -- SAME rate used for Task #317 wave 7's POL, this session, for consistency; Orion reports its headline DFS figures in both ZAR and AUD, not USD, so this conversion was necessary to populate a USD-named field at all); post-tax IRR=26% (a companion secondary-source figure independently states 26.2% -- both refer to the same DFS headline, 26.2% used as the more precise of the two). PRE-TAX: NPV=ZAR9,966M/AUD797M, IRR=31% (not written -- after-tax per repo convention). Total project capex (incl. contingency) AUD607 million/ZAR7,592 million. Metal price assumptions: copper US$9,401/t, zinc US$2,665/t, gold US$2,160/oz, silver US$27/oz. Orion also holds the earlier-stage Okiep Copper Project (Namaqualand, South Africa) which has its own, separate, less-advanced feasibility work in progress as of 2025-2026 (per company disclosure) -- NOT combined with or substituted into Prieska's figures above, per the playbook's multi-project rule.
