Im new to investment in Iron ore explorers/developers,but understand that the capex for SDL is est$4bill.hoping to produce $35mill TPA.SDL require formidable rail infrastructure thru 500Km of jungle and have to contend with operating in the Cameroon.Compared to all that,ARH looks like a walk in the park.Of course,I know there is a lot more to consider and would appreciate anyone with experience in this industry presenting their analysis,the good,the bad,and yes,the ugly.BTW,do we get to see the DFS?
BTW,I cant help bragging about my last post,one day B4 the stock took off,that it was time to BUY and to be strong and courageous("your day will come"),and it did,the very next day!!!
