The ED occurrence is located 1.5 kilometres east of Lower Belle Lake and 2.3 kilometres northwest of Mount Gordonia in the east-central part of the Toodoggone Gold Camp, approximately 244 kilometres north-northwest of the community of Germansen Landing.

The ED showing consists of a zone of massive pyrite with some chalcopyrite occurring in a small shear within volcanic rocks comprising green, porphyritic andesitic tuffs and other pyroclastics of the Upper Triassic Stuhini Group. At the showing, the Stuhini Group is undivided and monzonite and syenite dikes cut these volcanics. A major fault structure is inferred to run north-south along the Belle lakes valley. A second fault, striking west-northwest, separates Toodoggone volcanics in the south from Upper Triassic Stuhini Group volcanics in the north. These consist of massive, aphanitic to porphyritic basalts and andesites with minor breccia. Where porphyritic, phenocrysts are mostly pyroxene. For a detailed description of the regional geological setting refer to the East Ridge occurrence (094E 179).

Mineralization at the ED showing consists of a stringer of massive pyrite with some chalcopyrite occurring in a small shear (Assessment Report 2506). This was reported in 1970 and subsequent property exploration does not provide additional information. In 1986, six soil samples taken from the vicinity of the ED showing yielded silver values of greater than or equal to 1.0 gram per tonne silver (Assessment Report 15070). A rock sample taken in the same year, 500 metres northeast from the showing, analyzed 0.7 gram per tonne silver and 0.003 gram per tonne gold (Assessment Report 15070). Monzonite and syenite dikes on the west side of Lower Belle Lake forms a prominent alteration zone. The zone is marked by a strong gossan with 2 to 4 per cent disseminated pyrite with analyses yielding less than 0.1 per cent copper (Assessment Report 15070).
