Zinc is up 6 cents to a new multi-year high of $1.40... and BCK is looking to create a resource estimation @ Blende that currently sites on a historic open pit resource of 19.6Mt averaging 3.04% Zn, 2.80% Pb and 56 g/t Ag (shallow, sulphide-only), representing 1.3B lbs of Zn, 1.2B lbs of Pb and 35.3M oz of Ag. As per the fact sheet on their site... interesting.
