"Has to be good sign if they are bringing in a new drill rig, rather than redeploy an existing - right?"... No.

This ore body requires some serious infill drilling for bankable study, people may have forgotten the ore zones are folded like a pretzel and highly unreliable over short distances. Reserve drilling would be the major explanation why MH did such a big CR recently imo. Low CR price indicates nothing material discovered so far, low confidence in the targets not yet drilled, and possibly urgent need for additional ore tonnes to make the LOM sing also imo. Of course you always want more resources, they are incrementally highly valuable, but what's niggling me is the difference between want and need...
