The Creston Hill occurrence is located about 3 kilometres southwest of Kitchener.

Regionally, the area is underlain by the peri-cratonic Middle Proterozoic Purcell Supergroup, a thick succession of siliciclastic and lesser carbonate rocks. The Purcell Supergroup is well known for hosting a number of significant deposits that include the Sullivan (082FNE052) sedimentary-exhalative lead-zinc deposit and the Troy copper-silver deposit in Montana.

More locally, the area of interest is underlain by the Aldridge Formation. The Aldridge Formation is the lowermost division of the Purcell Supergroup. It is composed of turbiditic siliciclastic rocks, quartzofeldspathic wacke and siltstone and numerous gabbro sills and/or dikes of the Middle Proterozoic Moyie intrusions. The focus of exploration in the Aldridge Formation is the contact between the Lower Aldridge and the Middle Aldridge which corresponds to the time of deposition of the Sullivan deposit. In this particular area of the Purcell basin, the contact between the Lower and Middle Aldridge is somewhat enigmatic in that there is no recognizable facies change.

This occurrence includes a 122-metre adit and opencuts within about 100 vertical metres upslope from the adit. Upslope, 100 vertical metres, there is a shallow shaft that was sunk on a well mineralized quartz-calcite vein 1.2 to 1.5 metres wide (Geological Survey Of Canada Memoir 228). Near the top of a gabbro sill the vein is well mineralized with chalcopyrite and pyrrhotite. The mineralization continues at depth for a distance of approximately 15 metres, where the vein becomes sulphide poor.

During 2004 through 2012, Eagle Plains Resources Ltd. completed programs of geological mapping, geochemical (soil and rock) sampling and airborne geophysical surveys on the area as apart of the Iron Range property. A completed property exploration history can be found at the O-Ray (MINFILE 082FSE017) occurrence.
