Detailed Mineral List:
| โ Aluminosugilite Formula: KNa2Al2Li3[Si12O30] |
| โ Andradite Formula: Ca3Fe3+2(SiO4)3 Description: Andradite from this mine is mentioned in the Cairncross reference (2013) as a general comment on page 151. |
| โ Baryte Formula: BaSO4 References: |
| โ Formula: Mn3+2O3 Description: Entry was based on dealer photo, reference (Cairncross 2014) for recent finds does not record this mineral at this mine but does confirm finds from N'Chwaning II mine in recent years 2010/2011. References: |
| โ Braunite Formula: Mn2+Mn3+6(SiO4)O8 References: |
| โ Brucite Formula: Mg(OH)2 References: |
| โ Calcite Formula: CaCO3 References: |
| โ Calcite var. Manganese-bearing Calcite Formula: (Ca,Mn)CO3 References: |
| โ Celestine Formula: SrSO4 Description: Discovered at this mine in October 2009 and April 2010 (Cairncross and Beukes 2013). |
| โ Despujolsite Formula: Ca3Mn4+(SO4)2(OH)6 · 3H2O Description: Rob Lavinsky (specimens analyzed by Dr. Robert Downs - University of Arizona)
Despujolsite is said to be first discovered at this mine in late 2010. Earlier finds 2005/2006 came from N'Chwaning II mine (Cairncross 2013). |
| โ Ettringite Formula: Ca6Al2(SO4)3(OH)12 · 26H2O Description: Ettringite, Jouravskite, Charlesite and Sturmanite cannot be identified visually. All specimens are at best a 'guess' unless analysed, there are no visual properties to distinguish one from another, other mineral associations do not factor either. References: |
| โ Formula: Ca4Mn3+2-3(BO3)3(CO3)(O,OH)3 Description: Members photo used as reference is erroneous, the specimen is from N'Chwaning II mine, gaudefroyite has not been recorded from the # III mine. (Debbie Woolf) |
