The difference in market cap represents many years of project development + a massive difference in proven JORC compliant reserve + a massive difference in proven DSO.
BRM's market cap has only JUST (in the last few months) gotten above a point where it's valued higher then land fill, that's like 4 years in the making.
So I agree that DMA has potential, but it will have to go through the same pain that BRM went through to get there.
Ie, it could be many many years before you see the appreciation.
