i dont think IGC and NKP have the sole rights to the Genorah farms. im pretty sure there is a third party also...
however if you work on the 15% it doesnt matter if there are 2, 3 or 300 partners, IGC have 15% of the total.
and the 12 million + ounces is just an initial estimate, chances are extremely good that the resource will increase as more exploration takes place. IGC is definately a stock heading places imho.
