The interesting part of that is that there was more minerals they low or high is another issue , but it seams where ever they do drill or test they find more minerals at near surface , it seems the whole area has minerals in it at surface , which is cheaper to mine ,
Also IMO once they do start mining and have a cash flow , then they can start drilling deeper and hopefully find an even bigger resource , well thats what i would be doing . As a business you need a cash flow asap , so you can keep drilling and hopefully find a big resource , i dont think their No 1 job is to keep HC posters happy
