South Africa leads Mineral supply with 15.8% of suppliers, followed by Tanzania ( 10.5% ) and Germany ( 5.3% ) — a distribution across three key regions rather than a single dominant source of raw material availability.

8.3% of all listings were added in the last 30 days, indicating a steady but modest influx of new supply. 65.8% of suppliers remain active in the last 90 days, and 76.3% carry business verification — the base of listed suppliers is largely reachable and has undergone documentation validation.
