Sunrise Energy Syerston scandium study: capex, costs and mine plan for engineers
Reviewed by Tom Sullivan
First reported on MINING.com
30 Second Briefing
Sunrise Energy Metals has completed the feasibility study for its Syerston scandium project in New South Wales, outlining Phase 1 production of 60 tonnes per year of scandium oxide (Sc2O3) over a 32‑year mine life at a capital cost of $120 million and C1 cash operating costs of $534/kg. The laterite deposit, about 450 km west of Sydney, contains nearly 46 million measured and indicated tonnes grading 414 ppm scandium, positioning it as one of the largest high‑grade scandium resources outside China. With China supplying 80–85% of global scandium and tightening exports, Syerston is being framed as a key non‑Chinese source for aerospace aluminium alloys, solid oxide fuel cells for AI data centres, and advanced electronics.
Technical Brief
- Feasibility study confirms Phase 1 plant sized for 60 t/y Sc2O3 nameplate capacity.
- Syerston laterite resource update (2025) reports ~46 Mt measured and indicated at 414 ppm Sc.
- Project lies ~450 km west of Sydney, implying long overland logistics chain for reagents and product.
- Syerston is formally designated “of great importance to national security” by both US and Australian governments.
- China currently controls 80–85% of scandium supply and has imposed export restrictions, tightening non-Chinese availability.
- Sunrise positions Syerston as one of few scalable non-Chinese scandium sources able to supply aerospace and defence alloys.
- Sunrise’s co-chairman links scandium demand growth to AI data centre power systems, 6G architectures and solid-state memory chips.
Our Take
Within our 1100 Mining stories, scandium and scandium oxide appear only in several keyword-matched pieces, underscoring how unusual it is to see a dedicated 32‑year mine plan like Sunrise’s Syerston project in New South Wales.
At a capital cost of about A$120 million for 60 t/y of scandium oxide, Syerston sits at the smaller end of project capex in our Projects-tagged coverage, which may make it more financeable but also more sensitive to offtake certainty in aluminium alloy markets.
The 414 ppm scandium grade over nearly 46 Mt in Australia positions Sunrise Energy Metals as one of the few potential non‑Chinese primary scandium suppliers in our database at a time when China is estimated to control 80–85% of global supply, which could appeal to US and Middle East buyers looking to diversify sourcing.
