Formula:
Cu3AuHg0.4Sn0.7
Co-described with chemically very similar UM2000-03-E:AuCuHgSn. The two are said to form a continuous solid solution.
Assoacites: Hg- and Cu-bearing gold, sperrylite, Sn-Pb intermetallics. Found as "an equant grain, 30–40 µm across,
with a highly irregular periphery", with magnetite- and pyrite-in amphibolitic alteration zones.
