The Ace 9 showing is centred on a mountain peak, 1 kilometre south of Natlan Peak and 27 kilometres northeast of Hazelton.

Widespread, low-grade, chalcopyrite and less abundant molybdenite mineralization occurs in the contact area between a diorite stock of the Late Cretaceous Bulkley Intrusions and Middle Jurassic to Lower Cretaceous Bowser Lake Group argillites and greywackes. The diorite also intrudes the sedimentary rocks as sills up to 30 metres wide. Quartz porphyry and granodiorite also occur in the area. Pyritization is prominent in several rock types.

Two occurrences are reported on the Ace claims a galena- sphalerite (Ace 5 showing, 093M 037) showing to the southwest and a stibnite showing located in the Ace 9 vicinity.
