The only reason IMO not to disclose immediately if results are positive might be to stick some more stakes in the ground if there are positive indications outside our claim areas...
"waste more time staking claims?--drill something already"--wait for it :-)
but I think they'll hold all the good stuff "pretty close to the vest", especially as the plan was for Geotech to only fly HM...lots of other claim land won't be flown.
