The Battle copper occurrence is located in the north eastern Brooks Range, approximately 4 kilometres north east of Johnson Lagoon.

The area is underlain by Lower Jurassic Bonanza Group volcanics comprised mainly of andesitic to rhyodacitic lava, tuff and breccia. On the Battle claims, the Bonanza Group andesite flows with minor intercalated sediments are cut by numerous andesitic to diorite dikes. A small diorite stock intrudes volcanic rocks on the Battle 2 claim. The intrusives are related to the Jurassic Island Plutonic Suite.

Locally, mineralization consisting of pyrite, pyrrhotite and chalcopyrite occurs in the volcanics and intercalating sediments. Up to 15 per cent pyrite is disseminated throughout the rocks with minor associated pyrrhotite and chalcopyrite.

In 1974, Kennco collected thirty samples from the mineralized zone yielding an average of 0.05 per cent copper (Geology, Exploration and Mining 1973, page 256).
