ORESTONE COMPLETES AIRBORNE MT SURVEY CAPTAIN PROPERTY
Orestone Mining Corp. has completed an airborne MobileMT survey on the Captain gold-copper porphyry project near Fort St. James, north-central British Columbia. The magnetotelluric survey was flown collecting electromagnetic and magnetic data with precise positioning to track the low-resistivity signature of sulphide-related gold-copper mineralization and define the limits of a non-mineralized but conductive graphitic argillite unit intersected in hole C22-01.
The survey was completed over a 40-square-kilometre area by Expert Geophysics Ltd. of Aurora, Ont., at a cost of $52,000. The survey consisted of a total of 215 line kilometres flown over 26 east-west lines of 7,000 metres, each spaced at 200-metre intervals and four north-south tie lines spaced at 2,000 metres.
Data received by the company cover 13 EM frequencies from 26 hertz to 17,099 hertz. The EM data were inverted to obtain the distribution of resistivity with a depth over a depth range of two kilometres. The results of the survey will be analyzed in detail and reported in the coming weeks.
"Given the extensive overburden cover at Captain, Orestone elected to carry out an airborne MobileMT survey over the entire property as a cost-effective and efficient exploration tool. MT geophysical surveying is a deep-seeking, electromagnetic method typically employed for defining deep structures, geothermal systems and targeting deep mineralized systems such as porphyry deposits. Examples of large buried porphyry deposits associated with strong resistivity lows (conductivity highs) are the Resolution mine in Arizona, the Collahuasi and El Salvador mines in Chile, and the Pebble deposit in Alaska," stated David Hottman, chief executive officer and director of Orestone.
The 100-per-cent-owned Captain gold-copper project encompasses 96 square kilometres, and hosts a large gold-dominant porphyry system located 41 kilometres north of Fort St. James and 30 kilometres south of the Mount Milligan copper-gold mine in north-central British Columbia. The Captain project features relatively flat terrain, moderate tree cover, and an extensive network of logging and forest service roads suitable for exploration year-round.
