One thing you are forgetting in your BRM/DMA market cap comparison is the value of iron ore contract prices have gone up considerably since BRM made their resource upgrade in 2008.
DMA was definitely undervalued in Feb @ 20c and yet they still have only risen 7.5c in almost 12 months.
Completely flown under the radar that whole time & hopefully the market will wake up this week and rerate it accordingly.
