The SNOWFIELD COPPER occurrence is located on a high plateau, west of Thunder Creek and 3.3 kilometres southeast of Mt. Loes, approximately 45 kilometres west of the village of Gold Bridge. The showing lies approximately 900 metres northwest of the Copper 6 occurrence (Minfile 092JW052) and is the extension of the Windy zone, in the north-central region of the Bridge River project property.

The area is primarily underlain by the Early Tertiary-age granitic Bridge River Pluton, which intrudes the Late Cretaceous quartz diorite to the southeast and a similarly aged granodiorite body, the Lord River Pluton, to the north, west and southwest. The intrusive rocks are overlain by flat-lying Miocene-age basaltic flows (Garibaldi) and intruded by basalt to diorite feeder dikes and felsite, quartz porphyry and felspar porphyry dikes.

To the southeast of the Snowfield occurrence, four zones (Showing #3, Contact, Windy and West) of mineralization are exposed near the contact with the overlaying Miocene basalts over an area of 400 by 1000 metres. The zones consist of a mineralized quartz stockwork hosted by silica and sericite-altered granites of the Bridge River pluton. Mineralization consists of chalcopyrite, bornite and tetrahedrite. The zones are west-dipping and primarily north to northwest trending, 025 to 040 degrees.

Locally, copper mineralization is hosted by granodioritic intrusive rocks and exposed along the margins of a snowfield.

In 2010, a grab sample (187183) assayed 0.687 per cent copper and 14.1 grams per tonne silver (Assessment Report 32065).

During 2005 through 2019, Cresval Capital Corp. completed programs of prospecting, geochemical sampling, trenching, an induced polarization survey, 2031.5 metres of diamond drilling in nine holes, an airborne magnetic and radiometric survey and a ground magnetic survey over areas of the property known as the Copper 1-25 claims, the Bridge River project and the Mike property.

In 2010, a 400 by 350 metre copper soil anomaly was delineated over the Contact and Showing #3 zones and a 550 by 125 m gold-arsenic-zinc soil anomaly at the Windy zone, northwest and peripheral to the Contact zone. Cresval changed its name to Transforma Resources Corp. in October 2021.
