TORONTO, ONTARIO--(Marketwired - Sept. 6, 2016) - Rockcliff Copper Corporation ("Rockcliff") (TSX VENTURE:RCU) today announced that a second phase drill program on the Talbot property is planned to commence in October. The fully permitted program is planned to include between 10-15 holes totalling approximately 5,000 metres and will focus on three areas centered on high priority targets. The majority of the drilling will focus on expansion of existing resources (high grade Talbot Deposit) and discovery of additional zones of gold-rich Volcanogenic Massive Sulphide (VMS) mineralization at the North Copper Zone and the Central Target Anomaly. The property is strategically located in the prolific Flin Flon-Snow Lake greenstone belt, the most prolific and highest grade VMS District in Canada and the largest Paleoproterozoic VMS District in the world.
