RE:Aris Mining insitu gold valuation supports $90 per share? Not all resources are valued the same. A more conservative Aris valuation is to give Soto Notre and Toroparu resources a value of Zero. There are reasons for this. Soto Notre could be completely denied an environmental license (as had been done before) making that project's value zero. Toroporo's resources at fairly low grade and the project is in the middle of nowhere. Bringing that project to production probably will run $500 million in investment and take 7 - 10 years.
