I think the narrowness of the vein is more or less known. There won't be any step out as it seems vein hosted mineralisation and not a sedimentary deposit? ...again I'm no geo or engineer just a HC reader.
They have a pit design shown in a previous ann - the very high grades I guess make it a goer, though if
@mineralised has doubts... If Aisha is also as thin with grades as good I just wondered if underground is the way to go...Maybe it will depend on the depth of other targets.
I'd really like a geo comment on where these veins come from too. Does anybody know if there are any in previous anns? Is it worth putting a drill down to 300/400 meters? Hopefully any payday is not Admiral Bay (1 km) deep.
Maybe I'm getting greedy but a great sodding huge lump of 800 x 300 x 100 meters of 30% zinc at a recoverable depth for underground mining sounds pretty good to me once these veins are mined.
