Actually, I'm sort of puzzled that the announcement of switching from 0.75 oz/t ore to 2.45 oz/t ore didn't move the price up. If people here had been asked to predict the price after an announcement like that, I think $1.25 wouldn't have been so outlandish.
All I can figure is that buyers are waiting for reports of gold and silver production, revenue, and making payments to GHDC. Also maybe more "official" assay results.
