The Green Gables West showing is located 16 kilometres west- southwest of Vernon, between lower Whiteman Creek and Okanagan Lake.
In this area, Devonian to Triassic sedimentary and volcanic rocks of the Harper Ranch Group are unconformably overlain by Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks. These units are intruded by Middle Jurassic granitic rocks of the informally named Terrace Creek batholith. Feldspar porphyry dikes, of possible Tertiary age, cut the granitic rocks. Eocene Penticton Group volcanic rocks overlie the igneous and sedimentary rocks.
Altered and brecciated Middle Jurassic quartz monzonite hosts fluorite mineralization. Within a 600 by 300 metre area, fluorite occurs as: lenses and irregular masses in irregular drusy quartz veins, thin veins and films on fracture planes. The main showing is a fracture zone which dips 50 degrees east and strikes 020 degrees. The fluorite fracture fillings and veins generally range from 1 to 10 centimetres thick. The fluorite is coarsely crystalline with grains up to 2 to 3 centimetres across. It is usually pale green, with occasional white, yellow or purple varieties reported. Fluorite crystals are occasionally coated with silica.
In 1966, Canex Aerial Exploration Ltd. carried out trenching and drilling. In 1968, Kelver Mines Ltd. conducted geological mapping, trenching and drilling and in 1971 Cerro Mining Company of Canada Ltd. conducted geological mapping and a hydrogeochemical survey. In the 1980s the area was explored for gold mineralization.
