The Dort 3 East occurrence is located on the south side of a small ridge, in the head waters of Mariposite Creek, a tributary of Goldway Creek.

The area is underlain by Upper Triassic Takla Group volcanics. These volcanics are bounded to the east by the north-trending Dortatelle fault and to the west by the Ingenika fault. Locally, the area is underlain by andesitic volcaniclastics, predominantly crystal and lapilli tuffs, interlayered with minor andesite flows. Minor feldspar porphyry dikes intrude the volcaniclastics. The general stratigraphic trend is north-south but this is complicated by intense polyphase deformation. The regional metamorphic grade is greenschist facies, locally overprinted by biotite grade thermal metamorphism.

Locally, sericite, carbonate and ankerite altered massive sediments host quartz veins with disseminated pyrite and trace mariposite. In 1994, grab sample (KP 0224) assayed 9.7 grams per tonne gold (Assessment Report 23682).

In 1985, BP Resources completed a program of geological mapping and rock, silt and soil sampling on the area as the Goldway claims. In 1994, Noranda completed a program of soil sampling and a ground magnetometer survey on the area as the Jo 4 claim. In 1994 and 1995, Hemlo Gold Mines completed programs of rock and soil sampling, geological mapping and a ground magnetic survey on the area as the Dort 1-4 and Jo 4 claims. In 1996, Catalyst Ventures, on the behalf of Battle Mountain Gold, completed a program of geological mapping and rock sampling. In 2012 and 2013, J.B. Kreft prospected the area.
