They Acme showing is hosted within Upper Triassic Stuhini Group augite porphyritic andesite approximately 200 metres southwest of a contact with Triassic (Hickman) quartz monzonite.

A vein was found in outcrop in one location, and could be traced for 75 metres uphill in float and frost-heaved rubble. In outcrop, the vein is 38 centimetres wide, strikes 120 degrees/85 degrees north, and consists of quartz with 15 per cent sphalerite, 2 per cent galena and less than 1 per cent chalcopyrite. A chip sample across this vein (32656) yielded 10 parts per billion gold, 76 grams per tonne silver, 0.9 per cent lead and 9.46 per cent zinc (Assessment Report 21016). The vein is flanked to the north by 90 centimetres of silicified augite porphyry which contains 0.01 per cent copper, 0.032 per cent lead, 0.062 per cent zinc and 4 grams per tonne silver (32657) (Assessment Report 21016). This quartz vein is significantly anomalous in base metals, assaying up to 1.08 per cent copper (32652), 11.4 per cent lead (32655), and 9.46 per cent zinc (32656). Some of these veins are also silver-rich, with assays up to 1,141 grams per tonne (sample 459084); however, all samples returned insignificant gold values (Assessment Report 21016).
