Just calculated the metal per ton out - its $~77 per ton dirt - using recorded high silver and gold prices, and assuming 100% recovery? I believe 70-80% recovery from heat leach is realistic (not accounting for any mining dilution 15% is a typical number achieved subject to ore body shape.
So let's use a conservative 10% mining dilution and 80% heap leach recover so 30% less of $77 per ton dirt makes it $53.90c per ton dirt (so like half a gram of gold).
mining cost and processing cost (heap leach has massive up front capital earth works costs and interested loan payments) and it may take several years before its actually producers any return!
What is the waste strip ratio? you have to move waist dirt of 5.8 ton of waist to 1 ore so another $20-25 mining costs this is very conservative number to get ore this adds to the cost of mining and upfront costs etc.. Now we have $33 per ton dirt - how much is earth works, debt/interest costs and chemicals to run the leach pad?
Also, corporate costs - it's starting to look tight, and I suspect they will need to drill out 3 to 5 times more ore to make it economic and have enough scale to make it pay itself off.
From prospectus: This study assumed gold and silver recoveries of 75% and 85% respectively and
determined a strip ratio of 5.8:1
