RE:RE:Rio invests in copper production !I agree the Utah investment is not directly related to Casino, but we can gain insight into the financial calculations that are making sense for RIO to secure additional copper supply in the short term. They are basically paying $500M USD now, to produce a 10-year revenue stream of around $230M a year. (based on $4/lb copper) I think the key point of the Utah transaction is that it produces revenue quickly. Casino does not produce revenue quickly, so there is less incentive for them to invest right now.
