Hi sydney
Check out Teck's old Afton mine in Kamloops BC. One mill w/several pits being mined at the same time. I've been there many times. Tecks been doing it for decades and is likely the world's foremost expert in mining from several pits at the same time.
"The original Afton copper deposit was found by Chester F. Millar in the mid-1960s and was operated as the Afton Mine following Teck's acquisition of Millar's company. Teck operated the Afton mine -- including two satellite pits, Crescent and Pothook -- and the East and West Ajax pits intermittently from 1987 until 1997."
Fact is, based strictly on tecknical expertise/experience Elmer couldn't of found CUU a better partner to develope SC.
Want to hear interesting stories? LOL, none better than the ones about "the Ranch" and the goings on there at the main house that Teck actually owned after buying the mine property.
ttfn
