RE:RE:RE:RE:j kaiser on SIR and FEXFair question, greenviewkid, but I haven't spoken to the company to ask those questions.
That being said, the budget was pretty tight on the first part of the Daewoo earn-in ($800k expenditure for 5%) and SIR probably didn't want to use any of their own cash given that they've been running on fumes for years and finally have a cash balance again. It is also possible that the drilling company ran out of casing so they couldn't go any deeper - these holes are very deep at a depth of up to 909 m, which I take to mean the vertical, so at 60 degrees (guess), that's almost 1,050 m.
All that we know is that one of the holes ended in mineralization, SIR (operator) thought it was good enough to go to the expense of leaving the casing in the ground, and that they felt there was a good chance that Daewoo would likely fund additional drilling if they choose to go to 35% (by spending an additional $7 million on exploration).
