The ice road is indeed being developed as we chat.
However it is not coming from the northwest at Duncan Lake.
It will be developed from Bluefish Hydro along the route from Prosperous Lake which would allow drilling activity at Clan Lake to be supported from the main camp at Giauque Lake and the Ormsby deposit.
Ice thickness depend on what will be travelling the roads. If only pickups then 18 inches are enough. Heavier equipent may need 24 inches. Semi traffic will need 30-36 inches.
I understand they are now drilling Engineering holes at the Ormsby deposit to aid in Pre-Feas syudies.
Things are looking up.
