Having actually worked the Bigsky area let me make these comments.
Yes it has potential, but so does almost any area between Yellowknife and the Nicholas Lake deposit.
Saying it is adjacent to the Con & Giant is not accurate, similar geology but NOT adjacent.
In this area the old ORO deposits are the jewels, definately not the Bigsky.
There would need to be at least 10-15 years of intensive drilling in the area to even come close to gauging its true potential, at close to $500.00/m once the core is racked away.
With the hopelessness of permiting in the NWT added to the equation you need to ask... Is it worth it?
If the Ormsby/Nicholas deposits were anywhere else in Canada they would be mining now.
In Tyhee's portfolio the priority list was; Ormsby, Nicholas, Clan, Oro, Bigsky and finally Goodwin. This does not reflect gold content but best bang for the buck work scenarios.
In the future it might be determined that Clan has more ounces than Ormsby??
My 5 cents worth.
