See Pretium’s press release for yourself. The stock is currently down around 26%. Here’s one juicy tidbit from the press release:
Strathcona withdrew from the Program on October 8, 2013 before any results from the processing of the bulk sample were available. In withdrawing from the Program, Strathcona advised Pretivm that “…there are no valid gold mineral resources for the VOK Zone, and without mineral resources there can be no mineral reserves, and without mineral reserves there can be no basis for a Feasibility Study.” They also advised that “…statements included in all recent press releases [by Pretivm] about probable mineral reserves and future gold production [from the Valley of the Kings zone] over a 22-year mine life are erroneous and misleading.”
Strathcona is saying that there is no gold (“no valid gold mineral resources”).
