Capsule Geology

The Peacock (Hunter) occurrence is located at an elevation of approximately 920 metres on the east side of Clapperton Creek and approximately 7 kilometres north-northeast of the community of Nicola.

Regionally, the area is underlain by three north-south–trending Jurassic batholiths: the eastern Wildhorse Mountain Batholith, the central Nicola Batholith and the western Guichon Creek Batholith. Compositionally, the batholiths are zoned from an exterior diorite rim to a quartz monzonite core. The batholiths intrude Nicola Group volcanic and pyroclastic rocks with minor limestone, argillite and conglomerate.

The occurrence area is underlain by granitic rocks of the Lower Jurassic Nicola Batholith. Locally, the intrusive rock is hornblende-biotite granodiorite that has undergone widespread chlorite-epidote alteration and exhibits strong foliation striking northeast and dipping steeply to the west. To the southwest is the intrusive contact of the granodiorite with green to purple andesite, volcaniclastic rocks and intercalated sediments belonging to the Upper Triassic Nicola Group. The Nicola Batholith is intruded (?) by a northwest-trending tongue of quartz monzonite that is fine-grained and foliated near its margins and coarse-grained and massive elsewhere. Numerous faults strike approximately 030 degrees with dip angles 50 degrees northwest to vertical and appear to have been the locus of some horizontal displacement.

The Peacock showing contains several shallow shafts in the narrow gorge of Clapperton Creek that expose several large, sparsely mineralized quartz bodies up to 12 metres across, connected by veins and stringers. Copper mineralization occurs in the quartz veins and is occasionally disseminated in the granodiorite. The veins are up to 60 centimetres in width and strike north in general alignment with foliation and fractures. Many veins occur in areas of aplite dikes. Mineralization consists of bornite, chalcopyrite, malachite and azurite, usually associated with minor pyrite.

In the 1940s or early 1950s, sampling of a trench is reported to have yielded 0.34 gram per tonne gold, 39.3 grams per tonne silver and 3.1 per cent copper over 13.5 metres (Property File - 811079).

In 1992, a sample (53063) assayed 1.03 grams per tonne gold, 35.4 grams per tonne silver and 1.69 per cent copper (Assessment Report 19933).

In 2010, a sample (no. 1) from the Clapperton Creek (Peacock) occurrence area yielded 4.98 grams per tonne gold, 287 grams per tonne silver and 21.4 per cent copper (Assessment Report 35529).

In 2012, two samples (29 and 30) yielded greater than 1 per cent copper each with 9.3 and 17.5 grams per tonne silver and 0.377 and 0.633 gram per tonne gold, respectively (Assessment Report 33375). These samples were later re-sampled and yielded 1.33 and 2.31 per cent copper, respectively (Assessment Report 35529).

In 2015, three float samples (P4, P5 and P7) from the Peacock occurrence area yielded from 2.71 to 6.78 per cent copper with 34 to 83 grams per tonne silver (Assessment Report 35529).

Work History

Several historic shafts, tunnels and trenches are reported to have been developed on the occurrence during the first half of the 1900s.

The area has been explored in conjunction with the nearby Turlight (MINFILE 092ISE055) occurrence and a complete exploration history of the area can be found there.
