The Borin Creek placer deposits lie a few kilometres to the northwest of the gold-bearing veins of Blackdome Mountain, a possible source of the gold in the Borin Creek gravels. The underlying bedrock consists of Eocene volcanics and sediments which overlie altered granodiorite.
The Borin Creek gravels are probably of Quaternary age, representing, in part, reworked Pleistocene glacial and fluvioglacial gravels which are regionally extensive. In 1968, a plant, including a three metre trommel, was established on the Borin Creek prospect. Production from this plant is not known.
