The Confluence occurrence is located about 600 metres north-northeast of the confluence of Wutluk Creek with Twentynine Mile Creek, approximately 30 kilometres east-southeast of the community of Elko.

The Confluence occurrence consists of disseminated galena occurring in an area where a Cretaceous stock, consisting of trachyte and syenite, intrudes sedimentary rocks of the Mesoproterozoic Purcell Supergroup and is in thrust-fault contact with siltstone of the Upper Cretaceous Alberta Group a few hundred meters to the east. The intrusive rock is reported to be silicified and altered. The siltstone is also silicified. Sample R84-135, collected by Cominco Ltd. in 1984, assayed 0.42 per cent lead, 0.017 per cent copper, 24.9 grams per tonne silver, and 0.024 gram per tonne gold (Assessment Report 13242, Plate 5).

In 2006, 6 diamond-drill holes were drilled on the Howell property owned by Eastfield Resources Ltd. One of these holes (hole HW-605) was put down 150 metres east of the Confluence galena showing (Assessment Report 28853). This hole was reported to have intersected 15 metres of weak copper mineralization mostly hosted by a fine-grained mafic sill(?) intruded in a much silicified and veined younger shale sequence (possibly belonging to the Alberta Group (Assessment Report 30526). The mineralization was considered a 4th style of mineralization found on the Howell property consisting of weak chalcopyrite with more ubiquitous pyrite in alkalic porphyry.
