 · The gold itself is dissolved in the H 2 S-bearing fluid as the fluid is being formed via devolatilization (Phillips and Powell, 2010), and pyrite is being converted to pyrrhotite (e.g., Ferry, 1981; Tomkins, 2010). About 3–15 t Au km − 3 of rock may be dissolved assuming 80% efficiency of gold extraction (e.g., Phillips et al., 1987).
