So how do we explore for Porphyry Copper Deposits which are completely covered by barren younger rocks? Well let's back up a bit, we know that porphyries form under large subduction related volcanoes and that most of these are located under the ring of fire around the subducting pacific plate another fertile subduction zone occurs in Balkans, Turkey, and Pakistan.

Sample 1 – Potassium Feldspar – Laboratory work conducted on a potassium feldspar (typically <150μ) produced some excellent results. The feldspar had an iron content of 2.5 % and the target was to reduce this to <0.1%. The first tests, conducted on a HI Filter with a background field of 0.65 Tesla, reduced the Fe2O3 level to 0.165%.
