The oldest rocks in the Egg area are complexly folded and metamorphosed schists and gneisses, and mafic volcanics (basalt) all of Devonian age and belonging to the Stikine Assemblage. These are overlain by Devonian to Permian, white to grey, crystalline limestone and other sedimentary and volcanic rocks, also of the Stikine Assemblage.

In November of 1987 a set of orthophotographic maps were prepared to cover the Ret 2 7 claims and a structural interpretation was completed by Pamicon Development on behalf of Northwest Gold Syndicate. An airborne geophysical survey was conducted the same year consisting of 40 kilometers of Airborne magnetics and EM.

In 1988, OreQuest Consultants Ltd conducted an exploration program on the Joy 3, Ret 2-7 and Ver 1-2 claims on behalf of Pezgold Resources Corporation.
