The Robex Deposit is a polymetallic zinc deposit estimated to contain approximately 1 Mt @ 1.9% Zn, 0.6% Pb, 0.15% Cu, 13.5 g/t Ag and 46.5% BaSO4 1. This historical estimate was deemed reliable in a 43-101 Technical Report published in 20132. In 1997, Groupe Consortium Quebec and Bumigene completed an economic study of the Robex Deposit (Robex, 1998 M&A circular). The Deposit appears to remain open along strike and at depth.
The reader is cautioned that no qualified person has done enough work to classify these historical estimates as current mineral resources or mineral reserves and the Company is not treating the historical estimates as current mineral resources or mineral reserves. As most of the historic core and drill logs used to estimate the historic resources of the Robex Deposit are presumed to be lost, the deposit needs to be entirely re-drilled and a new resources estimated to confirm the historic estimates.
