I think before we sell out for £1.65 we need to read the Hardman & Co report by Paul Mylchreest. They have literally only scratched the surface at Empire :
Besides the substantial skarn potential, there is also the possibility that Empire is
part of a larger mineralised porphyry molybdenum-tungsten system or porphyry
copper-molybdenum system subjacent to the sulphide veins.
Similarities with Antamina
The largest and best-known mines worldwide, based on skarn deposits, include:
? Antamina – in the Andes, and one of the world’s largest copper-zinc mines.
? Ok Tedi mine – a copper-gold mine located in Papua. It was believed to be the
biggest copper-gold deposit worldwide when mining began in the 1980s.
? Cantung mine – in Canada’s Northwest Territoires. It was the largest source of
tungsten in the western world prior to its closure in 2015.
The high proportion of endoskarn at Empire is potentially significant, since it bears
a similarity with Antamina, which is also “abnormally abundant” in endoskarn. The
Antamina deposit is located in the copper belt of the north Andes. Like Empire, it
was formed in the the Eocene period by emplacement of quartz monzonite
intrusions into cretaceous limestones.
