RE:Situ FactI remember seeking this article in mining.com about three years ago. So it's not "new" news in the true sense but is still a valid presentation. Mr. Sutton makes a strong case for the feasibility of in-situ leaching.
Dispite periodic questioning about ISL, no one, on this board at least, has shown any scientific evidence that ISL won't work. So far, it seems to be working just fine in Florence.
The only in-situ risk I see is if the ore body underground is not as fractured as the thousands of core samples indicate.
The solution has to flow through fractured rock much as water flows through a glass with ice cubes. If the solution encounters solid rock, as opposed to fractured, the solution is going nowhere. According to the thousands of core samples taken from the North Star deposit I don't think we have to worry about that.
By the way, the map of tne entire Excelsior land holding indicates that North Star takes up only a small portion of the land footprint. It is my understanding that other areas contained within the total holding are also fractured and are conducive to ISL. These areas of the property could be opened up to copper recovery in the future.
As always, everyone is encouraged to do their own due diligence.
