The area is underlain by propylitized monzonite, intruded by a diorite stock (Jurassic Nelson Intrusions) and by dykes of diorite, andesite, and felsite porphyry (Eocene Coryell Intrusions).

Fluorite occurs in minor fault breccia on Ram 10, Wewa 29, and Ram 30, and accompanied by minor chalcopyrite on Wewa 29. A molybdenite-bearing quartz vein cuts felsite porphyry on Ram 9.

R.M. Reininger conducted geochemical and magnetometer surveys on the Wewa 1-40 claims in 1971. H. Veermans and B. Botel held the Wewa and Ram claim groups in 1974. In the same year, Brascan Resources Limited optioned the property and conducted geological mapping, a magnetometer survey over 17 line-miles and geochemical surveys comprising 635 soils and 80 silt samples. The area was restaked as the Screeching Cat in 1978. This is likely the same occurrence as Wewa (082FSW349).

In 2006, Astral Mining Corporation conducted a helicopter-borne geophysical (electromagnetic) survey on the area as a part of the JJ property.
