In my opinion, there seem to be a number of pro's and con's with this stock and i suppose it is a personal decision as to which case is stronger. from what i see:
pro's: very large acerage near and next to current proven resources. limited exploration done on their tenanments (this is also a con!) so potential upside is massive enough money in the bank (short-term) to fund exploration
con's: management's past history limited exploration done just issued heaps more shares and options. assuming all options are exercised in 3yrs time the # of shares on issue is 0.5billion - to put this in perspective that is a share price of $2 for DUO (based on a $1m market cap like SFR) with a 'Degrussa' find - which was called 'once in a lifetime'.
I'm sure others will have plenty more in both camps.
