Description
As at 28 February 2025
Copper 360 Limited is South Africa's only JSE-listed primary copper producer (JSE: CPR). Holds mining rights to over 70% of the O'Okiep Copper District in the Namaqua Copper Belt (19,260 hectares; over 12 historical mines and 60+ prospects). Operates two segments: (i) Copper Concentrate via the Rietberg underground sulphide mine feeding the Modular Flotation Plant 2 (MFP2) at Nababeep, commissioned March 2024; (ii) Copper Cathode via the Solvent Extraction Electro-Winning (SX-EW) plant processing oxide rock dumps, placed on care-and-maintenance in H2 FY2025. A second flotation plant (MFP1) is under construction (paused at ~75% completion). Multi-Mine Strategy feeds multiple small operations into the centralised Nababeep processing hub. Near-term target: 40,000 tpm ore at ~1% Cu = ~5,000 t Cu p.a. Recapitalisation rights offer of up to R1.15bn announced September 2025.

Solvent Extraction Electro-Winning (SX-EW) plant at Nababeep, producing copper cathodes from oxide rock dumps and TSFs. Received first phase upgrade in H2 FY2024 with production improvements seen in H1 FY2025. Lower recoveries led to a temporary suspension of cathode production in September 2024, and the plant was placed on a care-and-maintenance programme during H2 FY2025. A second phase upgrade is planned that is expected to significantly increase output; requires further expansion capital. The expansion capex will only be incurred once the concentrate operations are at sustainable level. R113 million impairment charge recognised in FY2025 financial statements.

Assumptions
- The projects listed here reflect the information captured in this workspace and are not necessarily a complete picture of the company's portfolio. For authoritative figures, refer to the company's official filings.

How to read this tab
- The tables below list unit codes most often used in the Base Metals sector for this company. MetalPilot stores contained metal or product in the codes below; grade and tonnage use separate fields. In side-by-side comparison views (stock page Portfolio tab, watchlist By sector), heterogeneous source units are converted to each commodity's preferred display unit (for example Moz Au, kt Cu, MMbbl oil) before summing; the same canonical codes appear in project data.
What the Portfolio tab shows
- The Portfolio tab presents a project-level view of the company's reported assets, built from publicly disclosed information (technical reports, annual filings, MD&A, investor presentations, MRMR / R&R statements, NI 43-101 / NI 51-101 / SEC S-K 1300 / SEC S-K 1200 / JORC / SAMREC / PERC / PRMS / COGEH filings, and similar primary sources).
- Figures are grouped by project type (mining, oil & gas, royalty, stream, processing facility, development, portfolio aggregate) and are shown alongside the headline reserve base, headline production, headline grade / quality, cost benchmarks, estimated lifetime, commercial terms (for royalties / streams), operational capacity (for processing) and a single-figure rating where the underlying data supports one.
- Each data table on the Portfolio tab is followed by ONE Assumptions footnote describing the modelling choices for that table; KPI stat-card assumptions appear in the bottom block instead. All legal and section disclaimers are merged into a single disclaimer list at the bottom of the Portfolio tab.
Concepts in your sector — Base metals
- Cu % / Zn % are the grade norm for base metals; kg/t is for very high-grade deposits. Porphyry copper is typically 0.3–1% Cu; SEDEX zinc 5–15% Zn.
- C1 vs C2 vs C3 vs AISC. C1 is direct mining + processing + transport + by-product credits. C2 adds depreciation; C3 adds corporate/indirect costs. Compare like for like.
- TC/RCs (treatment & refining charges) are smelter payments per dry metric tonne of concentrate — a non-trivial part of base-metal economics, not shown on the Portfolio tab.
- Concentrate vs metal. Miners often sell concentrate (~25–30% Cu) and are paid for contained metal minus TC/RCs. Portfolio books contained metal on a 100% basis.
Portfolio tab — table guide
- Portfolio KPIs — company-level headline numbers aggregated from the featured projects (project counts, attributable annual production by commodity, attributable resource base by commodity, last filing date, operator share). USD value lines multiply attributable volumes by the resolved snapshot price.
- Portfolio snapshot — one-screen summary of the portfolio: counts by type and status, country mix, reporting standards used, operator share, primary commodity, attributable annual production summary and attributable resource base summary.
- Mining — one row per mining project, with columns for project name, location, status, primary commodities, production (with rating), reserves & resources (with rating), grade (with rating), costs and estimated lifetime. Multi-commodity projects emit one summary row per commodity.
- Royalty — one row per royalty interest held by the company. Columns cover the underlying project, operator, commodity, commercial terms (rate, type, cap, area-of-interest), attributable production, attributable reserves and estimated lifetime.
- Stream — one row per metal stream held by the company. Each row shows the underlying project, the streamed commodity, the headline stream percentage, the ongoing per-ounce / per-tonne payment, and attributable production / reserves.
- Processing facilities — one row per midstream / processing facility (pipeline, fractionator, LNG train, storage cavern, refinery, smelter, mill, heap-leach pad, CPP, etc.). Columns include nameplate capacity, contracted capacity, feedstock commodities and operational footprint.
- Development — projects in development status or in a pre-production lifecycle phase. The production column is re-labelled 'Targeted production (rating)' to highlight that the figures are plans, not actuals.
- Portfolio Aggregate — a single company-level row used when the company itself publishes a portfolio rollup (e.g. company-wide 2P barrels across all properties).
- Reserves & resources — detail — a leaf-category pivot showing every reserve and resource category disclosed across the projects.
- NPV (grouped) — all NPV rows captured from the filings, grouped by commodity, resource category, development status and pricing case. Each NPV figure is shown with its discount rate, basis (before-tax / after-tax), currency and value scale.
Ownership / Working interest
- Ownership percentage means the company's working-interest share of the asset: its slice of the project before royalties and before government take. It is shown on a 0–100 scale.
- Mines, oil and gas fields, and processing facilities — this is how much of the asset belongs to the company under that working-interest idea. One hundred percent is fully owned; a lower number usually means partners share the rest.
- Royalties and streaming agreements — the percentage is often not the story; what matters economically is usually the royalty or stream rate, shown elsewhere alongside these figures.
- Oil and gas — read this as gross working interest only. Do not treat it as net production or net wells after royalties; when filings distinguish gross from net, that shows up in how the resource numbers themselves are labelled.
- Below 100% — the short summary for each project names other owners and their stakes when the source says who they are.
- NRI vs WI (O&G). Working interest (WI) is the obligation to pay a share of costs; net revenue interest (NRI) is the share of revenue after royalties and overriding-royalty interests. A 100% WI well rarely produces 100% NRI; typical onshore U.S. NRI is 75–87.5% of WI depending on the lease royalty.
- Operator vs non-operator. The operator runs day-to-day operations; non-operating partners pay their WI share of costs but do not run the asset. Some Portfolio rows show operator share where disclosed.
Unit codes, conversion cheat sheets, cost benchmarks (AISC, C1–C3), reporting standards (NI 43-101, JORC, SEC S-K 1300) and resource/reserve category definitions live in the full terminology & units reference.
Each table lists the numeric band for scores 1–5 (production and resource base; grade where applicable for mining commodities) using the same thresholds as project rating stat cards. Only commodities that appear on featured projects for this document are listed.
Copper
Copper uses kt Cu bands (Mlb Cu when lb-scale copper resources appear on featured projects). Lithium grade uses hard-rock % Li₂O bands unless brine-style extraction or brine units appear on featured projects.
