The BORNITE occurrence is located at an elevation of approximately 2330 metres in an alpine cirque, 1.5 kilometres west of Nichols Peak, approximately 33 kilometres west of the village of Gold Bridge. The Bornite anomaly was found in 2012 by Miocene Metals Inc.

The area is underlain by biotite-hornblende-quartz-diorite of the Hurley River Pluton, which is assigned to the Late Cretaceous Scuzzy Plutonic Suite of the Coast Batholith, near the western edge of the quartz monzonite Miocene-age Bridge River Pluton. The property hosts scattered, potential porphyry Cu-Au related mineralization along at least three greater than 7-kilometre long northwest structural trends over an area of 15 kilometres. From west to east, the trends are referred to as the Bornite Trend, Tillworth Trend and Breccia Trend. The Bornite occurrence is within the Bornite Trend.

Mineralization in the Bornite Trend, which has an open-ended strike length of 7.5 kilometres, consists of scattered quartz-bornite-malachite ±chalcopyrite ±tetrahedrite veins and stringers up to 20 centimetres wide.

In 2012, four grab samples (M487873, M688012, M688013 and M487879) assayed from 1.64 to 4.34 per cent copper, 0.051 to 0.445 gram per tonne gold and 25.1 to 60.8 grams per tonne silver (Assessment Report 33341). In 2013, a float sample (N688075) of a quartz-feldspar vein with chloritic shearing and abundant malachite and azurite returned values of 8.55 grams per tonne gold, 408 grams per tonne silver and 32.2 per cent copper (Assessment Report 348850.

In 2010, Miocene Metals Inc. optioned the property and completed 1227 line-kilometres of combined airborne magnetic and gamma ray spectrometer surveys over area. The following year, a minor rock sampling program was completed. In 2012, Miocene Metals Inc. expanded the Mackenzie property from 36.3 square kilometres to 299.03 square kilometres, and followed the expansion with a program of geochemical sampling and a two-hole drill program. Sampling in the west led to the discovery of the Bornite Trend; sampling to the north led to the expansion of the Tillworth Trend, and sampling in the northeast identified the Breccia trend. The drill program focused on the Mackenzie showing, 7.3 kilometres east of the Bornite occurrence. Miocene's exploration focus in 2013 was on the Bornite Trend.

From 2015 through 2018 Carube Copper Corp's exploration efforts of mapping, geochemical sampling and an airborne magnetic radiometric survey focused on the Bornite Trend and then in 2019 focus was on area within the Bornite Trend and also areas of the Breccia Trend. The Breccia Trend was again the focus in 2022 under the newly named Mount Olympus property, operated by PrometheX Ltd.
