EMthethweni Wezamandla, amaminerali abalulekile achazwa njengamaminerali okungewona amafutha noma izinto zamaminerali ezibalulekile emnothweni we-US noma ezokuphepha. Bathathwa njengezinto ezithambile zokuhlinzekwa, uMnyango wezangaphakathi kufanele uvuselele isimo okungenani njalo eminyakeni emithathu ebeka endleleni entsha yoMthetho Wezamandla. Ama-USG acela ukuphawula komphakathi ngoNovemba 9th - Disemba 9, 2021.
