Still doesn't make commercial sense to me, if surface results are 50/50 and provide no substantial difference to underground resource, then it's a 50% chance you shoot yourself in the foot in terms of share price, therefore if the goal is to 'waste' money on surface work in the hopes to build excitement and then get a better CR (assuming this is the only commercial benefit to be discussed here) then it's committing to a spend with a 50% outcome? I don't think that's the case, from my experience surface results are indicative of resource, not 100% of the time, sure, but I have seen projects not proceed because of poor surface results so it's a key indicator for progression in many cases, and that's hinged on a resource viability decision - not a commercial one, and is being assessed by geo's, not BD people - all IMO, good to have balanced views on these threads I guess
