Tsumgallite is a gallium hydroxide mineral. The name tsumgallite is a contraction of Tsumeb and gallium (Schlüter et al., 2003). The mineral is isostructural with goethite and diaspore.
In a small vug, tsumgallite forms a pale off white powdery coating. The matrix consists of germanite and tennantite. Rare!
