Rockcliff Stakes Extension of High Grade Pen Zinc Deposit, Manitoba

TORONTO, ONTARIO--(Marketwired - Feb. 28, 2017) - Rockcliff Copper Corporation ("Rockcliff" or the "Company") (TSX VENTURE:RCU)(FRANKFURT:RO0)(WKN:A142TR) is pleased to announce it has acquired by staking the Penex zinc property (the "Property"), Snow Lake, Manitoba. The Property is strategically located approximately 4.5 kilometres southwest of Hudbay Minerals Inc.'s ("Hudbay") high-grade Volcanogenic Massive Sulphide Lalor mine and less than 200 metres from Hudbay's historic high grade Pen zinc deposit. The Property hosts the down dip continuation of the high grade Pen zinc deposit and now becomes part of the Company's Snow Lake Project, one of the highest grade base and precious metals property portfolios in North America. The Snow Lake Project is located in the Snow Lake mining camp located within the prolific Flin Flon-Snow Lake greenstone belt hosting high-grade precious and base metal deposits and mines.

Ken Lapierre, President and CEO of Rockcliff commented, "Staking of the Penex zinc property containing the down dip continuation of the high grade Pen zinc deposit was very strategic and timely. It underpins our commitment to acquire properties either by staking or acquisition that have significant metal potential within trucking distance to milling facilities in this world class base and precious metals camp. We feel confident that our 100% owned Penex zinc property will become a very strategic asset for Rockcliff."

Hudbay's high grade Pen zinc deposit hosts multiple zinc-rich lenses, strikes northeast-southwest and dips/plunges northwest. The deposit is located less than 200 metres on surface from the Property's northern boundary. All lenses of the Pen zinc deposit dip towards the Property's northern boundary and at least one of the zinc-rich lenses dips and plunges onto the Property at a vertical depth of between 300-350 metres. The deepest historical drill hole (CPen-03) on the Property intersected the deposit at approximately 475 metres vertical. The hole assayed 6.7% zinc equivalent across 2.6 metres within a much thicker zinc envelope of 7.6 metres grading 4.0% zinc equivalent. Bore hole geophysics completed in drill hole CPen-03 confirmed that the deposit's conductivity continued downward within the Company's Property and was strengthening at depth below the hole in an area completely untested by drilling.
