with the talk of economics and cutoff, and the fact that our COO and President is talking about Langmuir being a "high tonnage lower concentration" deposit, I had to google a bit tonight to see what different mining scenarios and open pit economics are out there.
I came across Hard Creek Nickel's NR on their Preliminary-assessment study on the Turnagain deposit. Heck these guys have numbers that look to be much lower than what our Micon report gave us last January. Granted they have some big tonnages too. This NR is one yr old (Mar 05/10) and used Nickel based on much lower prices as well. The are also looking at a pretty high processing rate per day though :) at 87,000 tonnes per day (tpd).
