I don't know about "same geology", as it being in the same formation, but I do believe that we are talking about both being drill and blast open pits, with a new mill being built to grind the ore and recover the gold by cyanidation. There are no existing mills with the capacity to handle 147 million tons of Oskisko ore in 15 years. (27,000 tons per day). OSK orebody is 1800 feet in total depth.

Barnat would be similar in rock integrity and mining method. That is the whole point in low grade wide ores. Only way to get at them is to pit blast etc.. few ores in Canada would qualify for rip and heap leach like Arizona/Nevada/Colorado, or Central/South American ores. Perhaps BC or AK has ores that would qualify. I don't know. Don't believe so though.

"Mineralization in the South Barnat Zone is located to the north and south of the old Barnat and East Malartic mine workings, largely along the southern edge of the Cadillac fault. The gold mineralization comprises multiple subvertical, tabular subzones hosted both in silicified greywackes of the Pontiac Group south of the fault contact and in schistose, carbonated and biotitic ultramafic rocks north of the fault contact. Porphyry dykes on both sides of the fault contain disseminated mineralization as well as late quartz veins containing visible gold. Gold mineralization in the South Barnat Zone likely extends to the east along the north and south walls of the past-producing East Malartic mine."
