Herzig et al. (1998): "Camera surveys…revealed widespread but discontinuous patches of stained sediment, suggesting that low-temperature diffuse hydrothermal vents were formerly active near the summit of the volcano"; note: Nautilus Minerals has tenements at Conical Seamount; submarine volcano in rifted forearc, New Ireland Fore-Arc Basin; Petersen et al. (2005): "Drilling at Conical Seamount significantly extends the known surface extent of the previously discovered vein-style gold mineralization (up to 230 g/t Au) at this site"; Herzig et al. (2003): "Gold-rich polymetallic vein mineralisation occurs in an outer zone of this area while arsenic sulphides together with abundant amorphous silica are found at the margins. More than 1200 kg of mineralized rock were recovered in 1998, consisting of stockworks and disseminated sulphides with gold concentrations locally reaching up to 230 g/t"
