The Huxley showing occurs in an area underlain mainly by basalt and andesite of the Eocene Kamloops Group located just south of Buse Lake, about 21 kilometres east of Kamloops. Blue agate occurs in veins and nodular form in andesitic volcanic rocks. In 1976, W. Huxley conducted trenching and digging in overburden over a 40 square metre area on the Huxley claim.
