The Blue Hammer showing is located south of Doctor Peak near the contact of the Middle Proterozoic Aldridge formation and the northern lobe of the Cretaceous White Creek batholith.

The discovery was made in 2003 by independent geologist, Jarrod Brown, MSc, during a reconnaissance traverse as part of a project jointly financed by the B.C. and Yukon Chamber of Mines and British Columbia Geological Survey on the Findlay property of Eagle Plains Resources Ltd.

Two gem quality beryl crystals, in excess of eight millimetres in diameter, were found along with dozens of translucent crystals less than three millimetres. Crystals discovered have been ice-blue, light-greenish-blue and white varieties of beryl. Locally, the occurrences are within an exposed 500 metre by 50 metre area of the White Creek batholith. Beryl occurs in pegmatite dikes cutting k-feldspar megacrystic quartz monzonite of the White Creek batholith.

A second, later beryl-bearing phase has also been noted. Walnut-sized vugs containing inwardly growing euhedral beryl crystals have been noted in quartz mica ± tourmaline greisen veins up to five centimetres wide (Press Release - Eagle Plains Resources Ltd., October 7, 2003).
