ReportFrom yesterday's B.S.
Look at page 10. This want to be anonymous writer says - The amount of acid consumed seems to totally ignore the possibility of carbonate minerals and iron oxides affecting the total required. Acid consumption of 10 lb of acid per lb of recovered Cu is very low compared to conventional (non-in-situ) copper leaching operations.
There is so much wrong here…. Excelsior’s acid consumption is twice the industry average for Arizona (however, ISR reduces overall mining costs). Most Arizona mines run from 3-5lbs of acid for each pound of copper produced. Florence is predicting 5lbs/lb. Thus, us easy to find online and the author clearly did no research.
Another glairing error is on the same page - The economic valuation seems to ignore the cost of drilling the overburden.
This is ridiculous, if you read the Excelsior FS NPV, the valuation included the cost of this drilling. M3 Engineering would not have signed off if it didn’t include this
