Two northeast trending skarn bands, up to 60 metres long, occur in Devonian to Upper Triassic argillites which are intruded by Oligocene granite of the Tkope River Intrusions. Test pits at the Gilroy showing on Schulz Creek expose magnetite, sphalerite, bornite, arsenopyrite and possibly greenockite in serpentine skarn. Argillite occurs in the hangingwall and footwall in one of the pits. One sample ran 6.86 grams per tonne silver and 0.31 per cent copper.
