The BORNITE NORTH WEST (Cauldron) occurrence is located on a northeast facing alpine slope north of Sorcerer SW4 Peak and east of Nichols Creek, at an elevation of approximately 2240 metres. The showing is approximately 35.5 kilometres west of the village of Gold Bridge.

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 (quartz diorite to granodiorite), 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 North West occurrence is at the northwest end of the Bornite Trend, although the trend may extend northward, perhaps to the Nichol (Minfile 092W009), approximately 4 kilometres northwest.

The Bornite Trend consists of scattered quartz veins hosting bornite, chalcocite, magnetite and lesser chalcopyrite and tetrahedrite as veins and stringers up to 0.2 metre wide and over an open ended strike length of 7.5 kilometres. Locally, quartz veins and stringers host clots and blebs of chalcopyrite and bornite. Mineralization is within both the Miocene-age Bridge River Pluton and the Coast Plutonic Complex.

In 2012, grab samples from the Bornite North West area assayed from 0.5 to 0.7 per cent copper (Assessment Report 33341). In 2016, a 1 to 2 centimetre quartz-magnetite-bornite-malachite vein sample (S843097) from a boulder in the Cauldron South zone assayed 1.84 per cent copper and 0.23 gram per tonne gold (Assessment Report 37311). In 2019, a 1 centimetre quartz vein from the Cauldron Zone, containing disseminated malachite, bornite, chalcopyrite +/- chalcocite with a potassium feldspar halo, assayed 1.1 per cent copper and 0.03 gram per tonne gold (Assessment Report 38530).

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 extension of Tillworth Trend, and sampling in the northeast identified the Breccia Trend. The drill program focused on the MacKenzie showing, 9.8 kilometres southeast of the Bornite North West occurrence.

Miocene's exploration focus in 2013 consisted of geological mapping, rock sampling (26) and a ground magnetometer survey along areas of the Bornite Trend. Of the 26 samples collected, eight returned copper values ranging from 0.37 to 32 per cent, five had gold values ranging from 0.12 to 8.55 grams per tonne, and ten returned silver values ranging from 1.36 to 408 grams per tonne.

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 areas 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.
