Cobalthead - If there was lots of low grade material there it would be altered and visually noticeable - and it would have been sampled in the past and a large low grade deposit, perhaps with a high grade core, would have been identified. But it wasn't - perhaps because these are narrow, high grade structures as have been mined over the history of the Barkerville camp. Mineral deposits don't just change their nature overnight. How do you  know what Mintec has been sampling? Or whether or not they are finding mineralization? Insider information or speculation?
