The O'ne-ell Creek occurrence is located on the southeast side of a northeast-southwest–trending ridge, approximately 7 kilometres west-northwest of Mount Sidney Williams.
Regionally, the area is underlain mainly by Mississippian to Triassic Cache Creek Complex sedimentary and volcanic rocks. Into these, ultramafic rocks of the Trembleur Intrusions have been emplaced.
The eastern part of the Bornite claim group, on the east side of Tildesley Creek, is underlain by fault-imbricated slivers of ultramafic rock, slate and siltstone, and greenstone. These rocks are inferred to represent either the North Arm succession or the Sitlika Assemblage imbricated with the ultramafic unit in the footwall of the Mount Sidney Williams ultramafic allochthon.
Locally, chromite occurs in serpentinized peridotite-dunite sills.
In 1998, a rock sample (B-26) from the occurrence area yielded 0.139 per cent nickel and 0.104 per cent chromium (Assessment Report 25668).
Work History
In 1995, Hera Resources Inc. completed a program of rock and soil sampling and five diamond drill holes, totalling 893.6 metres, on the area as the Bornite 1-11 claims.
During 1997 through 2012, Ursula Mowat completed programs of prospecting, rock sampling and geological mapping on the area as the Bornite property.
