The Phil 1 (Creek A) occurrence is located in the head waters of an unnamed creek flowing east in to Phillips Arm, at an elevation of approximately 870 metres. Anna Lake is located approximately 2.0 kilometres to the southeast.

The area is underlain by a persistent band, greater than 12 kilometres long, of stratified metavolcanic and metasedimentary rocks of the Upper Triassic Quatsino and Karmutsen formations (Vancouver Group). The band trends northwest and separates Jurassic to Cretaceous Coast Plutonic Complex rock of two different compositions, diorite and granodiorite.

Locally, a pendant of weathered andesite (?) hosts small, 5 millimetre, magnetite stringers. In 1983, a rock sample (0321F) assayed 0.635 per cent copper, 21.5 grams per tonne silver and 3.35 grams per tonne gold (Assessment Report 11218).

In 1983, Du Pont of Canada Exploration completed a program of rock and silt sampling and geological mapping on the area.
