The OK North deposit 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 is located near North Lake. The OK South zone (MINFILE 092K 057), lies 2.3 kilometres to the south.

Two phases of intrusions occur within the Jurassic to Cretaceous Coast Plutonic Complex. Granodiorite is intruded by an elliptical, 1.6-kilometre long quartz monzonite body, referred to as the OK Intrusive Complex and assumed to be Tertiary or younger. The dike-like leucocratic feldspar porphyry body is elongated north-northwest, varies from 30 to 600 metres in width, and has been inferred to be the core of the larger, variably altered granodiorite body. At least six phases of intrusions have been noted on the property, characteristic of many porphyry deposits. Later phases include narrow quartz-eye porphyries and postmineral diorites, which occur as north-northeasterly dikes and vary from 1 to 60 metres in width. Discontinuous andesite dikes represent the latest intrusive phase. Rocks in the vicinity of the OK South zone exhibit moderate to strong phyllic and argillic alteration. Elsewhere on the property, alteration is less intense and consists predominantly of propylitic alteration to chlorite and epidote. Post-mineralization, north-northwest–trending faults cut both granitic rocks of the Coast Plutonic Complex and the younger OK Intrusive Complex.

Mineralization occurs in fractures, quartz stringers, irregular veinlets, blebs and some disseminations. Mineralization of economic significance is primarily peripheral to the leucocratic feldspar porphyry in the granodiorite. 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 noted.

In situ reserves/possible resources at a 0.3 per cent copper cutoff grade are 68 million tonnes grading 0.39 per cent copper and 0.02 per cent molybdenum (N.C. Carter, personal communication, 1991).

A geostatistical study in 1982 of all drillhole data, which included seven mineralized zones (over a distance of 5 kilometres) for which sufficient data were available, estimated that combined drill-indicated and geological potential resources were 408 000 000 tonnes of greater than 0.24 per cent copper and 0.009 per cent molybdenum (CanQuest website). An independent report prepared in 1989 for CanQuest Resource Corporation further refined the 1982 geostatistical analysis to provide a "proven plus probable resource, recoverable by a selective open pit mining operation" of 104 900 000 tonnes of 0.46 per cent copper and 0.028 per cent molybdenum at a 0.4 per cent copper equivalent cut-off (CanQuest website).

Since its discovery in 1965, the OK property has been explored by a number of geological, geochemical and geophysical surveys and by more than 14 000 metres of percussion and diamond drilling. This work outlined several copper-molybdenum mineralized zones over a northerly trend 5 kilometres in length. Between 1966 and 1985, several companies (Asrco Exploration Company of Canada Limited, Falconbridge, Granite Mountain Mines, Western Mines, Aquarius Resources Limited) carried out the exploration work.

In 1994, CanQuest Resource Corporation optioned the property from Robert Edward Mickle of Likely, BC, 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.

In 1997, CanQuest Resource Corp. conducted geological mapping in the area.

In 1998, CanQuest Resource Corp. completed rock chip sampling, soil geochemistry, geological mapping and geophysical surveys.

In early 2003, Eastfield Resources Ltd. optioned the OK property from Robert Edward Mickle of Likely, BC. Later in 2003, Lumina Copper Corp. entered into an option with Eastfield Resources Ltd. for the OK property and conducted an exploration program of geological mapping, prospecting and bedrock sampling.

Lumina Copper Corp. dropped their option in 2004; Goldrush Resources Ltd. then optioned the property from Eastfield Resources Ltd. and conducted a geophysical survey.

In early 2005, Goldrush Resources Ltd. released a NI 43-101 compliant resource estimate which stated an inferred resource of 64 020 000 tonnes grading 0.34 per cent copper and 0.01 per cent molybdenum calculated with a 0.20 per cent copper cut-off grade (Press Release, Goldrush Resources Ltd., March 21, 2005). Later in 2005, Goldrush Resources Ltd. and Eastfield Resources Ltd. completed geochemical sample analyses and diamond drilling. Highlights include drillhole 05-OK-DH-03, which returned 185.5 metres grading 0.21 per cent copper (Assessment Report 28035).

In 2006, Goldrush Resources Ltd. assigned its option of the OK property to Prophecy Resources Ltd., and Eastfield Resources Ltd. and Prophecy Resource Corp. released updated resource estimates for the OK North zone of inferred resources of 86.80 million tonnes grading 0.31 per cent copper and 0.014 per cent molybdenum, calculated using a 0.20 per cent copper cut-off (Technical Report on the OK Copper Property for Prophecy Resources Corp. dated October 5, 2006 - www.prophecyresource.com).

In 2007, Prophecy Resource Corp. and Eastfield Resources Ltd. conducted soil sampling and diamond drilling. Highlights of the diamond drilling include drillhole 07-04, which returned 75 metres grading 0.34 per cent copper and 0.012 per cent molybdenum (Assessment Report 29477).

In 2008, Prophecy Resource Corp. and Eastfield Resources Ltd. completed six diamond drillholes on the OK property.

In 2010, Prophecy Resource Corp. was renamed Prophecy Coal Corp., and completed soil and rock sampling with Eastfield Resources Ltd. Highlights include sample 726869, which assayed 0.398 per cent molybdenum (Assessment Report 32091).

In 2011, Prophecy Coal Corp. and Eastfield Resources Ltd. completed IP and magnetometer geophysical surveys.

In 2012, Prophecy Coal Corp. and Eastfield Resources Ltd. conducted soil sampling.
