Begin with the material.

Choose the material, then describe its form and composition. Use the company role and location to narrow the search. Confirm that any potential buyer or processor can accept your exact material.

Copper is the current bounded source-backed research hub. Other material categories are discovery starting points; no live coverage, price or buyer availability is claimed.

Keep the grade attached to the evidence

State the physical form, composition or analysis, origin, contamination and quantity where known. Mark any missing information as unknown. A commercial role or published capability does not confirm acceptance of your lot.
