As referenced by Chris in the presentation, Lepanto copper-gold porphyry deposit in the Philippines exhibits similar high-sulphidation to intermediate sulphidation style of mineralisation characteristics above its porphyry deposit as to what is believed to occur for the Cayley Lode.
The interest in porphyry formation is the deposit scale could expand many times over. eg. IMHO, by as much as 100x if they strike the porphyry!!!!
Figure 7: Cayley Lode:
9.3 Mt at 1.23% copper, 0.23 g/t gold and 7.1 g/t silver, or 0.11 mt copper & 0.07 Moz gold
Figure 8: Lepanto Cu-Au porphyry deposit:
892 Mt at 0.5% copper and 0.7 g/t gold, or 4.6 mt copper & 19.8 Moz gold
