DELVE-19, the most recent report, is considered reliable (being plausibly aligned with earlier estimations) → 23,000
Min/max: also following DELVE-19 → 10,000 - 35,000
Female participation: no data. As ASM is mainly mechanized small-scale alluvial mining in the “Hinterland”, female participation is likely low (less needs for tasks like panning, mineral selection etc.). Possibly between 5% and 10%? → 2,000?
Gold: Data not disaggregated between gold and diamond but gold reportedly more important than diamonds. Possibly ~80% gold, ~20% diamonds. → 19,000

2019: 23,000
