The Centenial Creek showing is located on the north side of Allan Creek, later referred to as Centennial Creek, at an elevation of approximately 700 metres. The showing is approximately 27 kilometres northwest of the town of Gold River.

The area is underlain by Upper Triassic Karmutsen Formation (Vancouver Group) pillow lavas with minor interbedded limestone, which have been intruded by granodiorite of the Jurassic Island Plutonic Suite.

Locally, a zone of well-bedded, sulphide-bearing sediments varies in thickness from 1 to 20 metres. The bedding strata is from 1 to 10 centimetres thick and contains minor amounts of copper, lead, zinc, 2 to 7 per cent iron and increasing values of arsenic at depths.

In 1990, the contact between the Sicker sediments and Karmutsen volcanics was sampled across 0.8 metre and for a length of 2 metres and yielded 5.8 per cent copper, 0.044 per cent lead, 1.581 per cent zinc, 101.9 grams per tonne silver and 0.67 gram per tonne gold (sample 89072709; Assessment Report 20079).

2013 prospecting on the Preston property showed that chalcopyrite was found to be associated with K-feldspar, epidote ± garnet and amphiboles. The mineralization is spatially related to the contact metamorphism and metasomatism of the Karmutsen and Buttle Lake groups by the Island Plutonic Suite. Chalcopyrite is not confined to the skarnified limestone. In the north of the property the chalcopyrite is found as clots within the thick units of basaltic volcanic rock.

In 1965, Empire Development completed a program of prospecting and geological mapping on the area as part of the Nimpkish Copper property. In 1972, First National Mines completed a program of geological mapping and rock sampling on the area as the HK 1-2 claims. In 1990, the area was prospected as the Maybee A claim. In 1993, Noranda completed a program of airborne geophysical surveys on the area as part of the Muchalat property. In 1995 and 1996 the Centenial Creek area was prospected, stream sampled and rock sampled by Westmin Resources Limited, operating for Doromin Resources Ltd., as part of the Dragon property.

In 1996, R.J. Lightle prospected the area. In 2011, the area was prospected as part of the Preston property. In 2012 and 2103, Santa Fe Metals Corp., on behalf of British Pacific Minerals Ltd., carried out programs of prospecting, stream sediment and rock sampling on the Preston property. The sampling of mostly metasedimentary rocks returned anomalous values of copper (ranging between 0.0002 and >1 per cent) and silver (ranging between <0.1 to 3.3 grams per tonne). The sampling was followed up by a small microdrill program to determine the extent, style and potential of copper, silver, zinc, lead mineralization at the massive sulphide lens in Campbell Creek (092E 025), approximately 1 kilometre northwest of the Centenial Creek showing.
