Metallic mineralisation is due to addition of S, As, and Au during alteration. In contrast to many Otago gold vein systems, there has been no scheelite mineralisation. Carbonates have δ 18 O = +15.4 to +18.6, and δ 13 C = ‐8.2 to +0.5‰. The oxygen isotopic signature is similar to other Otago gold veins.
