The OK Breccia zone is located east of Okeover Inlet and south of Theodosia Inlet in the Bunster Hills. Powell River is located about 25 kilometres to the south. The OK North zone (092K 008) is located 3 kilometres to the north, near North Lake.
Mineralization occurs in fractures, as quartz stringers, irregular veinlets, blebs and some disseminations. Intrusive breccias peripheral to the granodiorite host the higher grade copper mineralization. Trenching and limited diamond drilling suggest a north-northwest trend to the breccia zone, which consists of rounded 2 to 5 centimetre clasts of varying lithologies within a fine-grained matrix containing a high percentage of sulphide minerals.
Sulphide minerals include chalcopyrite, molybdenite and pyrite with minor sphalerite and bornite. Minor magnetite is associated erratically with pyrite and chalcopyrite. Thin veneers of malachite, limonite and azurite are also present.
In 1979, Aquarius Resources Inc. completed trenching and diamond drilling on the OK property. Highlights included drillhole k-79-2, which returned 9.4 metres grading 1.5 per cent copper and 8.93 grams per tonne silver (Assessment Report 8748).
Sampling in 1993 by CanQuest Resource Corp. yielded values as high as 0.15 per cent molybdenum, 4.69 per cent copper, 32.9 grams per tonne silver and 0.48 gram per tonne gold (Assessment Report 23511). Rhenium occurs in grab samples in the area.
In 1994, CanQuest Resource Corp. optioned the property and conducted geological, geophysical and geochemical surveys and drilling.
In 1995, CanQuest Resource Corp. completed an IP geophysical survey that located an area of higher chargeability, which was drilled with a single drillhole in 1996. The single drillhole returned 1.95 metres grading 0.202 per cent copper (Assessment Report 24553).
In 1998, CanQuest Resource Corp. completed rock chip sampling, soil geochemistry, geological mapping and geophysical surveys. Highlights of the chip sampling include sample 157207, which assayed 3.025 per cent copper over 2 metres (Assessment Report 25594).
In 2003, Lumina Copper Corp. and Eastfield Resources Ltd. conducted an exploration program of geological mapping, prospecting and bedrock sampling. Highlights include sample LB-03-OK-18, which assayed 2.06 per cent copper (Assessment Report 27342).
In 2007, Prophecy Resource Corp. and Eastfield Resources Ltd. conducted diamond drilling on the OK property. Highlights include drillhole OK07-09, which returned 30 metres grading 0.36 per cent copper (Press Release, Eastfield Resources Ltd., April 7, 2008).
In 2008, Prophecy Resource Corp. and Eastfield Resources Ltd. conducted diamond drilling on the OK property. Highlights include drillhole OK08-06, which returned 3 metres grading 0.24 per cent copper (Assessment Report 30301).
