Project information
As at 31 December 2025
Description
As at 31 December 2025
Integrated magnetite iron ore mining and pellet production operation located in the north-west region of Tasmania, comprising the Savage River open-cut mine (Centre Pit and North Pit) and the downstream Port Latta pellet plant and port facility. Over 58 years of mining and production history. Mining in 2025 focused on ore delivery from Centre Pit (primary ore source) and continued cutback in North Pit; ore was blended with North Pit material and stockpiles to maintain pellet quality. The North Pit Underground Development Project (NPUG) progressed toward Final Investment Decision (FID), with limited decline development, installation of ventilation and pumping infrastructure, and a completed ventilation raise; underground contract mining commencement targeted for 2026/2028 subject to debt funding. Cut-off grades: 15% DTR for opencut and 28%-30% DTR for underground. Mining leases held by Grange Resources (Tasmania) Pty Ltd include 2M/2001, 14M/2007, 11M/2008, 4M/2019 and EL30/2003. Tasmanian state royalty regime applies (Mineral Resources Development Act 1995).

Project information
As at 31 December 2025
Description
As at 31 December 2025
Advanced open-cut magnetite development project located 90 km from Albany in Western Australia's Great Southern region, owned 100% by Grange Resources. Resource extends over 11 km of strike, with depths ranging from 50 m below surface in the west to 555 m in the east. The project is proposed as a pit-to-port operation comprising an open-cut mine and concentrator at the mine site near Wellstead, a 110 km underground slurry pipeline to the Port of Albany, dewatering and storage at the Port, and either transhipping from Berth 5 to Cape-size vessels in King George Sound (FS2024 base case) or direct loading from Berth 7 (FS2012 option). April 2025 Feasibility Study (FS2024) reduced the nominal concentrate production rate to 5 Mtpa with an initial mine life of 28 years; potential to expand to 10 Mtpa with further future capital investment. Installed load 79.3 MW; targeted concentrate at around 70% Fe. Tenements (held 100% by Grange Resources Ltd): M70/1309, G70/217, R70/61, L70/185, L70/186, L70/188, L70/201, L70/225. Search for joint venture / equity partners underway; bridging study to follow partner selection.

Mt Windsor Joint Venture
District · Reclamation · Ownership 30%
Project information
Description
Minority-interest legacy copper / gold / base-metals joint venture in North Queensland in which Grange holds a 30% interest via BML Holdings Pty Ltd (with Thalanga Copper Mines Pty Ltd as operator). The Joint Venture comprises multiple sub-interests (Reward Copper/Gold 31.15%, Highway Copper 30%, Reward Deeps / Conviction Copper 30%, Mt Windsor Exploration Gold/Base Metals 30%) and is now being rehabilitated for future lease relinquishment expected in 2045. A voluntary Transitional Environment Program has been entered into to identify and remediate sources of pollution on site. In June 2025, the Joint Venture entered into an Option Agreement with Highway Copper Gold Pty Ltd (HCG) granting HCG a 12-month call option to purchase the Joint Venture's assets and liabilities for total consideration of A$250,000. Mining leases ML 1571, ML 1734, ML 1739, ML 10028, ML 1758 held at 30% interest. Bank guarantees of up to A$2,462,465 are held to secure rehabilitation of the Highway Reward project.

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.
Iron
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.
Assumptions
- Presented values are denominated in currency of the country where the company is headquartered. Values like market capitalization might differ from the values visible in other parts of the page, where the currency is always USD.
