Guinea Bissau
ASM Population: 7,000
UBC-14 data is only statistically calculated but due to lack of other data, still the best available guess → 7,000 .
Min/max: +/- 2,000 appears reasonable, as no primary data are available → 5,000 - 9,000
Female participation: no data. Perhaps “African average” of 30% → 2,000.
Gold: All data are for ASGM.

Expected ASM population: 7,000 Estimated ASM gold production: 0.3 t/a
