The Womo occurrence is located in the north eastern head waters of Carpenter Creek, on the south eastern slopes of Mount Knauss.

The area is underlain by Lower Jurassic volcanics of the Hazelton Group and Upper Jurassic sediments of the Bowser Lake Group. The strata are comprised of laminated argillites, bedded tuffs and interbedded andesite flows. These have been intruded by granitic to dioritic rocks of the Eocene Carpenter Creek Plutonic Suite.

Locally, a zone of molybdenite-bearing quartz veins, measuring 100 metres by 800 metres, straddles a regional contact between quartz diorite to granodiorite rocks of the Cretaceous to Tertiary Coast Plutonic Complex and hornfelsic siltstones of the Jurassic to Cretaceous Bowser Lake Group. A 50- to 150- metre wide, northwest- trending biotite-quartz feldspar dike cuts the sediments.

Molybdenite and chalcopyrite occur as disseminations and as fracture and shear zone fillings within the fractured, silicified and carbonatized areas of the porphyry and sediments. The mineralization is associated with east-west striking quartz veins. Later intense shearing and carbonatization, with a consistent north-south trend, have locally truncated and redistributed the mineralized structures.

In 1966, rock chip samples yielded values up to 0.064 per cent molybdenum and 0.20 per cent copper (Assessment Report 00798).

In 1981, chip sampling returned a value of 0.049 per cent molybdenum over 2.4 metres and 0.53 per cent copper with 8.3 grams per tonne silver over 4.5 metres (Assessment Report 10440).

In 2007, samples 17 and 18 assayed 0.042 and 0.045 per cent molybdenum, respectively (Assessment Report 29151).

In 2010, a grab sample (WO-14-10) assayed 3.71 grams per tonne gold, greater than 100 grams per tonne silver, 0.131 per cent lead and 0.225 per cent zinc. Three other grab samples (WO-21-10 through WO-23-10) yielded values ranging from 0.557 to 0.749 per cent copper and 0.109 to 0.154 per cent molybdenum (Assessment Report 31853).

In 1966, Amax Explorations completed a program of geological mapping and water, rock, silt and soil sampling on the area as the Dug claims. In 1979 and 1980, International Prism Resources prospected and sampled the area as the Womo 1-2 claims. In 1981, Cominco completed a program of rock sampling and geological mapping. In 1994, the area was prospected as the Copper Top claim. In 2007, El Toro Mining completed a program of photo-geological interpretations on the area. During 2008 through 2013, Casa Minerals Inc. completed programs of prospecting, geological mapping, geochemical (rock and soil) sampling and ground magnetometer surveys on the area as the Pitman property. In 2014, Abcana Capital Inc. entered into an agreement with Casa Minerals to acquire the Pitman property. During 2015 through 2017, Abcana and Casa Minerals completed programs of prospecting, reconnaissance geological mapping, and soil and rock sampling on the Pitman property.

In 2018 a 223 line kilometre airborne combined versatile time domain electromagnetic (VTEMTM) and aeromagnetic survey was conducted over the Pitman property (including WoMo) for Casa Minerals Inc. (Assessment Report 37955). In addition, a structural analysis was conducted on the property as well as investigations in the high elevation Gold Dome/WoMo area (Assessment Report 37735).
