The Slim Creek (Discovery) occurrence is located on the south west ridge of an unnamed mountain (Peak 8597) in the Dickson Range, at an elevation of approximately 2550 metres. The occurrence is south of Slim Creek and north of the Bridge River, approximately 65 kilometres northeast of Pemberton.
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. The property hosts scattered, possible porphyry Cu-Au related mineralization over an area of several kilometres.
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. The area is part of the Tillworth trend, which extends for approximately 13 kilometres.
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).
In 2012, a diamond drill hole (MMK-002) intercepted 4.3 metres assaying 0.83 per cent copper, 0.043 gram per tonne gold and 0.010 per cent molybdenum, including 1.1 metres assaying 2.23 per cent copper and 0.36 metre assaying 4.47 per cent copper, 0.059 gram per tonne gold and 0.060 per cent molybdenum. Another drill hole (MMK-001) intercepted 0.2 metre assaying 0.24 per cent copper (Assessment Report 33341).
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. Sampling to the west led to the discovery of the Bornite trend, sampling to the north led to the discovery of the Tillworth trend, extending approximately 13 kilometres and sampling to the northeast identified the Breccia trend. Together with the original discovery (Mackenzie; MINFILE 092JW 043) these define a zone of mineralization that extends approximately 12 kilometres outwards from the contact of the Miocene Bridge River Pluton. The drill program focused on the Mackenzie showing.
