The below from BMV rns is another strong positive:
I like the fact that he says, Early low cost mining & plenty of scope to re-open and mine multiple areas at one time. - not sure how this will be done or the low cost to complete this, but does sound very promising?
"In those days substantial blocks of ore would have been ignored as their grade would have made mining them uneconomic.
Many of the areas declared 'unpayable' in those days are expected to be economic because of the higher gold price, more efficient mining techniques and better recovery technology. In addition, our information suggests that the mine closed without a systemic program to salvage any of the predeveloped stopes, pillars, remnants, broken ore and vamping. This is highly significant to Bluebird as it means there can be good potential for early, low-cost mining. An added bonus is a tailings dam that could be a retreatable asset"
"The Gubong mine is a large mine which gives us plenty of scope to re-open and mine multiple areas at one time."
