Arsenogoyazite

Arsenogoyazite was found at Tsumeb in 1986 and was the first strontium-bearing mineral reported from the mine. It occurs as sub-mm, milky-white rhombohedrons, on hematite and quartz (Keller and Innes 1986; Gebhard 1999).

Bowell and Mocke (2018) described arsenogoyazite associated with austinite, conichalcite, hematite, malachite and quartz, on specimens they believed to originate from levels 30 and 32 in the second oxidation zone. One specimen from 32 Level, and another from 34 Level, was said to include arsenocrandallite in association with arsenogoyazite. Further work is required to confirm these observations.
