The DISCOVERY (Slim Creek) occurrence is located on the southwest ridge of Tillworth Mountain in the Dickson Range, at an elevation of approximately 2540 metres. The occurrence is south of Slim Creek and north of the Bridge River, approximately 25.5 kilometres west of the village of Gold Bridge. The Mackenzie and SC 32 showings are in the same vicinity.

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 Discovery occurrence is within the centrally located Tillworth Trend.

Locally, a linear, oxidized and brecciated structure hosts quartz with malachite staining and chalcopyrite mineralization over widths of 0.2 to 2.0 metres and a length of approximately 150 metres. The zone strikes from 150 to 170 degrees and dips 30 degrees to the east.

In 2003, five rock samples assayed (Assessment Report 28331):

In 2011, six grab samples assayed from 1.92 to 8.66 per cent copper, 0.009 to 0.443 gram per tonne gold and 0.85 to 12.3 grams per tonne silver along a 120 metre trend (Press Release, Miocene Metals Inc., December 9, 2011).

The showing was discovered in 2003 and staked in 2005 by Dr. Kenneth MacKenzie as the Caspar 1 to 6 claims. During 2003 through 2009, small exploration programs were conducted on the MacKenzie property every year.

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 at the MacKenzie showing, 700 metres north of the Discovery occurrence. Sampling to the west led to the discovery of the Bornite Trend, sampling to the north led to the expansion of the Tillworth Trend, and sampling to the northeast identified the Breccia Trend. 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 areas within the Bornite Trend and also targets of the Breccia Trend. The Breccia trend was again the focus in 2022 under the newly named Mount Olympus property, operated by PrometheX Ltd.
