The Witch project is a porphyry Cu-Au target in the northern Quesnel Trough of central BC, which hosts several deposits nearby.
The project has road access with active logging on property.
Exploration Highlights
The property covers prospective, multi-phase, porphyritic felsic to intermediate apophyses of the Hogem Batholith, representing a large alkalic porphyry system.
The eastern portion of property has had extensive grid soil sampling and IP plus minor diamond drilling by a Rio Algom-Westmin joint venture in early to mid-1990’s. Based on high grade soil and trench results, the JV completed 1323m drilling in 9 holes at the Moss Showing in 1991, returning up to 347 ppm Cu and 0.064 ppm Au over 52 m.
3 holes totalling 301 m, tested the Witch Showing area in 1995, returning up to 17.8 m at 0.082% Cu and 7.8 m at 0.094% Cu.
In 2004, based on historical data and new IP and geochem, Amarc Resources drilled 15 scattered holes for 2166 m in the area, returning up to 51.8 m at 0.045%Cu.
In 2011, Logan Resources conducted geochem, geology and IP surveys. Their exploration outlined km-scale areas of anomalous Cu-Ag-Au-As-Mo soils, magnetic intrusions, alkali alteration and chargeability anomalies (>20 mV/V).
To date, diamond drilling has consisted of shallow, widely scattered drill holes testing highly divergent targets. Nonetheless, drilling has returned anomalous copper values over 10’s of metres in several areas.
An east-northeast structural trend through the property, defined by anomalous soil geochemistry, magnetic response, topographic lineaments, and intrusive contacts, could provide focus for future drilling. Of note is the prevailing ice direction from the south-west to north-east.
Additional unexplored magnetic anomalies are present in the southwest part of the property, on strike from the main anomaly, with associated reconnaissance scale soil anomalies.
Outlook
This area is re-emerging in BC Cu-Au porphyry exploration spurred by the active Mt. Milligan mine, plus the discovery of the Kwanika and Kemess North and Kemess East deposits in the last decade.
Witch is a large property with compelling, untested, coincident IP and Cu-Au geochem anomalies that are well situated with respect to prospective alkalic intrusions.
To date extensive thin drift cover combined with the smaller footprint of alkali porphyry systems has largely frustrated the search for additional discoveries.
Newer geophysical techniques such as a ZTEM survey may lead to additional targets.
Excellent road access in low topographic relief areas, which will aid in low cost exploration, including diamond drilling.
100% held property.
