The worry is that the laboratory excuse is wearing thin since the lab itself has been reported to have said they are caught up.Therefor the suspicion BMK are sitting on at least some results they have in hand. If so then one could assume, rightly or wrongly, that they aren't rushing to release because they aren't too good.
One thing BMK has done is hold on to all their claims instead of rushing to parcel them off to jv partners. Noront's rush to sign jv's with very junior and poorly funded partners doesn't make much sense to me. So just maybe I should be more favourable to BMK than I have been.
