Mar Mar's specialty is earth moving. Maybe they have more experience than I think (from reading about the company a bit) at bringing a heap leach operation to production. I know that startup operations rarely go smoothly, as this one surely has not. Maybe the new guy will help.
That said, imo, they are still flying a bit too blind, seeing as most all gold miners prove up reserves first. They may think the entire ore body is worth mining, but it isn't possible to know for sure, yet. And when one examines the entire length of each drill hole Argonaut drilled, the overall grade comes way way down...meaning lots of overburden to sift through..
Also, keep in mind that they did choose to start excavating some of the high grade material, so, the grades will drop way off when they get to the main ore body.
Also, I seem to recall hearing/reading that MarMar was let go/kicked off from th El Herrudura mine....fwiw...maybe nothing....
