RE:Here's the million $ question and why you're doomed....I'll make it even more simple for you....In order to disolve and extract the copper you have to disolve the carbonate rock at the same time. There is NO avoiding this. In the webinar he showed you a sample rock..there is carbonate and copper intertwined with one another and there is no way to get at one without disolving the other...no way, no how, not now, not ever.
These wells would have to be on permanent flushing mode. The second they hit the indentical rock with fresh acid they start disolving the copper and the carbonate rock. There is no way to do one and then the other. This is going to be the case over every single cubic meter of the entire project. Every drop of acid injected is going to create CO2 forever and ever. It cannot all be disolved and then go back in to recover the copper. It would take the entire life of the project to rid it all of all CO2 producing rock.
It's the wrong rock! Taseko rock isn't carbonate, they built a pilot plant, they've tested recoveries and cannot encounter this problem because they have the right rock. Excellsior has the wrong rock. The entire wellfield is going to fizz and there's absolutely no way around this.
Flushing over and over again will remove what carbonate is disolved but new acid has to encounter new rock to get new copper so it MUST encounter new carbonate too!
You're making a terrible mistake and not thinking this through if you're relying on "Hope" and "hype" and "maybe"
