I don't think analysts ever put out 43-101 estimates? They may suggest what their expectations are but a 43-101 is a factual document which gets people into hot water if not done correctly by the mining/exploration company.
I think this is the wild card, a bulk sample first followed by the 43-101 giving the 1st year production expectations and proven probable reserves. There are enough core samples done to make the resource valuations exceptional,at least the way I see it? When that's done you will see more analysts coming out of the wood work with valuations. Right now all everyone is doing is guessing and getting ready for a nice ride up in the share price as the year progresses.
