Jerritt Canyon Mine, page-2

Hi @Joelstar I am guessing Big springs is refractory ore , not so bad given next door Jerritt Canyon use to and probably has a roaster .
Interesting to see in WA8 presentation that the diagram shows Big Springs is open from around 200 meters below surface , but already has around 1,000,000 oz, so is that around 5000 Oz per Vertical Meter (OVM) ?
If so to get that high a OVM which would be at least twice the ounces per vertical meter of SPRs Never Never deposit , would that mean a very long strike length to compensate for the relatively low grade and relatively narrow ore body ?
Would be nice to see a long section of Big Springs to validate that suggestion .

(We use to kick rocks and old stampers around in the Battle mountain area of Nevada over 20 years ago , a lot of history there and had some great times getting stuck out there in a two wheel drive pick up .
