GeologyAfternoon,
Just had a look back at the release from hole 1 then did a Wiki on the substances metioned to gain a better understanding of what was found.
Pyrrhotite does not have specific applications. It is mined primarily because it is associated with pentlandite, sulfide mineral that can contain significant amounts of nickel and cobalt
Chalcopyrite is the most important copper ore. Chalcopyrite ore occurs in a variety of ore types, from huge masses as at Timmins, Ontario, to irregular veins and disseminations associated with granitic to dioriticintrusives as in the porphyry copper deposits of Broken Hill, the American cordillera and the Andes.
Chalcopyrite is present in the supergiant Olympic Dam Cu-Au-U deposit in South Australia.
Chalcopyrite may also be found in coal seams associated with pyrite nodules, and as disseminations in carbonate sedimentary rocks
and what they metioned in the release
" Hole AT-10-4 is a 650m hole in which the entire bottom 300m of this hole contains intermittent and varying amounts of finely disseminated sulphide mineralization consisting primarily of chalcopyrite and pyrrhotite within an andesite host rock."
So lets hope that the entire 300m that they talk about showing varying mineralization is heavy in Chalcopyrite as this means we are sitting on a lot more copper than previously thought.
Have a good one.
