Materials

A curated range of raw materials, available through direct industry relationships.

Copper ore, raw

Copper Ore

Grade: 10–25%

Copper ore is rock that contains enough copper to be mined and processed economically. It’s crushed and milled, then concentrated before smelting and refining into usable copper, like cathodes — mainly for electrical wiring, electronics, construction, motors, and renewable tech like solar panels and wind turbines.

Copper concentrate after processing

Copper Concentrate

Grade: 25–32%

Available through direct industry relationships.

Tungsten ore concentrate

Tungsten Ore Concentrate

Grade: 30–70%

Tungsten is used where you need extreme hardness or heat resistance — cutting tools, drill bits, wear-resistant parts, and heavy-duty industrial applications. It also shows up in lighting and electronics, thanks to having one of the highest melting points of any metal.

Tin ore

Tin Ore

Grade: 65%

Tin ore is mainly refined into tin metal, vital for solder in electronics. It’s also used in tin plating to prevent corrosion, in alloys like bronze, and in tin-plated steel for food cans — big in electronics, packaging, and metal alloys.
