The Newton Creek showing occurs at the confluence of Newton and Granite creeks, 16 kilometres due west of Princeton.
Several quartz veins and shear zones cut argillite, andesite, limestone and breccia of the Upper Triassic Nicola Group.
The quartz veins are up to 2.4 metres wide and have been traced on surface over lengths of up to 460 metres. The veins contain disseminated pyrite, and have assayed trace gold and trace silver. A tunnel driven on a fault that diagonally cuts one of the veins encountered sheared quartz with pyrite and chalcopyrite. A sample of quartz assayed trace gold, trace silver and 0.20 per cent copper (Minister of Mines Annual Report 1929, page 279).
Narrow quartz stringers in argillite with high-grade gold are reported in the vicinity.
Several oxidized and leached pyrite shear zones have been exposed by trenching northwest of the area of quartz veining.
