Press releaseAn Induced polarization (IP) map is a map of mineral grains which charge up when the ground is electrocuted. Many ore minerals charge up but so do worthless minerals like Pyrite.
The IP map shows two big blobs of IP mineralization (pink) which are connected at depth. Previous drilling of this zone has revealed abundant Pyrite mineralization with minor Copper mineralization overlain by a Bornite blanket. Pyrite forms in abundance around porphyry centres. It is not the target. It surrounds the target. Two possible porphyry centres are outlined by grey dashed lines. They are within a larger Target corridor delineated by black dashed lines. You can think of the porphyry centres as vents for the Copper-bearing fluids. In a perfect world you would see a ring of Pyrite surrounding the porphyry centre. The fact that we do not see such rings could mean that the porphyry centres are tilted and that we are only seeing one flank, or, the system is so large that we are not seeing the whole thing, or, the rest is buried/faulted below the limit of detection (900m). Please don't forget that all of this is buried underneath the Hercules rhyolite.
Many ore minerals are electrically conductive. To get conductivity the mineral grains must be touching one another. Disseminated sulphides do not create a conductive rock. The Belmont target has very high conductivity meaning massive or stringer sulphides. Such sulphide concentrations can be found above and within porphyry centres.
Porphyry centres can have high concentrations of Magnetite which make them magnetic. They can also throw off Magnetite-Copper skarns. The magnetic targets are of great interest.
Combining everything together they have two big Porphyry targets within the IP area. I'm more interested in that Bornite blanket and if it is as extensive as I believe it to be it is going to make a huge copper mine!
