The B18 showing lies on the southeast flank of Ehahcezetle Mountain above Ealue Lake, approximately 10 kilometres southeast of the village of Iskut. Area bedrock consists typically of andesitic volcanic breccias and conglomerates of the Lower Jurassic Hazelton Group. Refer to the MFJ prospect (104H 001) for local history and more detailed geology.
A 0.3-metre-wide stained fracture with 1 to 2 per cent chalcopyrite occurs in epidote-chlorite altered andesitic breccia. The showing was discovered and sampled by members of the British Columbia Geological Survey Branch in 1996. A sample assayed 0.68 gram per tonne gold, 56.5 grams per tonne silver and 3.29 per cent copper (Open File 1997-3, Table 1, Sample B18, Field Identification Number RMA96-810).
In 2005, a helicopter-borne geophysical survey was carried out on behalf of Firesteel Resources Inc. on the Rok property. The survey comprised a new tri-directional magnetic gradiometer system, and a gamma ray spectrometer system. The airborne survey was flown at 200 metre line spacings with a total survey coverage of 611.4 line-kilometres.
In 2013, OZ Exploration Pty Ltd carried out an exploration program on the ROK Coyote project area, under a Joint Venture agreement with Firesteel Resources Inc (Assessment Report 35259). OZ drilled 1740 metres in 3 three diamond-drill holes, conducted 26.5 line-kilometres of 3D offset line pole-dipole IP/resistivity surveying and 316 line-kilometres of airborne magnetic and radiometric surveying. Eight MINFILE occurrences were covered by the airborne survey with four of these (MFJ, West, B18 and O.K) also occurring within the IP/Resistivity survey boundaries. The 8 MINFILE occurrences are: MFJ (104H 001), West (104H 002), South (104H 006), Hi (104H 014), Coyote 3 (104H 024), B18 (104H 032), Silver Standard (104H 045) and O.K. (104H 046). A total of 3500 hectares of geological mapping was also completed. A number of chargeability and resistivity anomalies were discovered, some of which were tested during the 2013 drilling. See MINFILE occurrences MFJ (104H 001), O.K. (104H 046) and B18 (104H 032) for drill results.
Drill hole DD13RK003 tested east-northeast trending magnetic highs coincident with historic chargeability anomalies which were replicated during the 2013 IP survey. It was reported that due to steeply incised valleys on the slopes of the plateau, the actual collar for this drill hole was not ideal for testing the target, being located much higher up the hill than originally anticipated. This drill hole was terminated early due to poor weather and excess snowfall. Total hole depth was 598.9 metres. In the core, rare chalcopyrite was noted within carbonate – epidote – hematite clots which were interpreted to be late remobilisations. Lack of porphyry mineralization indicators at the bottom of the hole was not encouraging. The closest documented mineral occurrence to this drill hole is MINFILE occurrence B18 (104H 032), located 390 metres to the east.
In 2017, Colorado Resources entered into a purchase agreement, with Firesteel Resources Ltd. to acquire a 100 per cent interest in the ROK-Coyote copper gold property. The ROK-Coyote property occurs immediately south and east on trend of Colorado’s North ROK property and immediately north and west of Imperial Metals Red Chris property.
On Sept 16 of 2020, Colorado Resources announced that it had changed its name to “QuestEx Gold & Copper Ltd.” effective September 28, 2020.
