Tyhee's cover letter to the remaining Information Request responses (http://www.reviewboard.ca/upload/project_document/EA0809-003_Cover_Letter_-_Responses_to_IR_s_March_28__2012.PDF) includes the following passage.

"Nicholas Lake, originally planned to provide approximately 25% of the YGP mill
feed has, after some investigations by the Feasibility Study Team been removed
from the current mine plan, a decision primarily related to the higher
concentrations of Arsenic in the Nicholas Lake ore, which would needlessly
complicate the submittal since Ormsby is the main focus of our actions. .
Removing Nicholas Lake ore from the overall YGP mill throughput significantly
reduces or eliminates potential environmental effects associated with Arsenic."

That may make permitting easier, but would seem to drop total gold production (all else being equal).
