Rockcliff Stakes Extension of High Grade Pen Zinc Deposit, Manitoba

TORONTO, ONTARIO--(Marketwired - Feb 28, 2017) - Rockcliff Copper Corp. ("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.

Rockcliff's fully permitted surface geophysical Deep Penetrating ElectroMagnetic (DPEM) survey has commenced on the Property. The DPEM survey will assist in determining the extent and depth potential of the conductivity related to the Pen zinc deposit on the Company's Property and will provide a framework for a diamond drilling program planned in 2017.

The following Pen zinc deposit longitudinal outlines the depth potential of the Pen zinc deposit above and below drill hole CPen-03. Borehole geophysics confirmed that the conductivity of the deposit was strengthening at depth below the hole.

Talbot Property Update:

Rockcliff continues its Phase 2 diamond drill program on the Talbot property. Three holes will test geophysical conductive plates below the north copper zone located 2.5 kilometres from the Talbot deposit and the north lens deep conductive plate located immediately below the Talbot deposit's north lens. The north lens deep conductive plate measures 300 metres by 600 metres and drilling will attempt to determine the economic significance of this plate.

The image below identifies the location of the north lens deep conductive plate to be drilled located below the Talbot deposit north lens and additional plates located in close proximity to the high grade gold-rich Talbot copper deposit.

The Snow Lake Project also includes a high grade former lode gold producer (Laguna gold property), a Net Smelter Royalty (NSR) on the Tower property (the T-1 copper deposit) in the FF-SL greenstone belt and the near surface MacBride zinc deposit located north of Snow Lake near Leaf Rapids, Manitoba. Additionally, Rockcliff owns a zinc-silver rich NI 43-101 Resource (the Shihan deposit) in Ontario and a royalty on two gold properties in Colombia, South America.

Rockcliff is well funded with approximately CDN$1.5 million in its treasury and no debt.
