The TILLWORTH CENTRAL occurrence is located on lower alpine slopes, 2.5 kilometres northwest of Tillworth Mountain, approximately 2 kilometres south of Slim Creek, at an elevation of 2100 metres. The showing is approximately 27 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. This is near the western edge of the quartz monzonite Miocene-age Bridge River Pluton.

Mineralization at the Tillworth Central occurrence and along the Tillworth Trend includes 3 to 100 centimetre lenticular quartz veins and stringers with clots and blebs of chalcopyrite, pyrite and malachite ±azurite ±bornite ±molybdenite. The Tillworth Trend extends northwest and southeast of Tillworth Central for greater than 7 kilometres.

In 2012, 10 rock chip samples assayed from 0.1 to 4.07 per cent copper, 0.022 to 1.455 grams per tonne gold and up to 48.7 grams per tonne silver (Assessment Report 33341).

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 the Tillworth Trend, and sampling in the northeast identified the Breccia Trend. The drill program focused on the MacKenzie showing, approximately 2 kilometres southeast of Tillworth Central. 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.
