The Timberwolf occurrence is located in the extreme southern headwaters of Matthew Creek, on the north side of Mount oOutram.

The area is underlain by Permian to Jurassic Hozameen Complex rocks comprised mainly of interbedded chert, argillite and basic volcanics. The Hozameen rocks are intruded by a Late Cretaceous or older quartz diorite intrusion. The Hozameen fault traverses south-southeast separating the greenschist facies rocks of the Hozameen Complex from unmetamorphosed Mesozoic rocks of the Ladner and Dewdney Creek groups. Ultramafic rocks are cut by greenstones of the Hozameen Complex and generally occur along the fault. There is shearing along this contact and in places the ultramafic rocks appear to be intrusive. The ultramafics that occur along the Hozameen fault are part of the Coquihalla Serpentine Belt.

The Timberwolf zone is underlain by altered Hozameen Complex greenstone and volcanic chert with argillaceous chert and bedded argillite. A major fault/shear trending 350 to 360 degrees with an apparent dip of 75 to 80 degrees west, exposed on the Master Ace claims (MINFILE 092HSW043) to the south, is indicated to extend across the property for some distance to the north east. The fault is indicated by a strong topographic feature in the form of a steep gully infilled by talus.

The argillites are in fault contact with serpentinized ultramafics with associated quartz veining along the fault. The cherty argillites host disseminated pyrrhotite immediately west of the fault. Scattered anomalous gold values are associated with these argillites. Vein material to the south of this showing hosts chalcopyrite, pyrrhotite and pyrite.

In 1986, a sample of oxidized vein material, as exposed on a steep cliff face, assayed 4.0 grams per tonne gold, 0.1 gram per tonne silver, 0.051 per cent copper, 0.005 per cent zinc and 0.004 per cent arsenic (Assessment Report 15323).

The area was originally explored in the 1920’s. In 1984 and 1985, Sheen Minerals prospected the area as the Timberline 3-5 claims. In 1986, Caara Ventures completed a soil sampling program on the area as the Timberwolf claim. During 2011 through 2014, minor programs of reconnaissance geological mapping, prospecting and trenching were performed on the area as the Master Ace property.
