Rockcliff’s Geophysical Survey Identifies Gold Targets at the Laguna Gold Property, Snow Lake, Manitoba

Toronto, ON – September 7, 2017 – Rockcliff Copper Corporation (“Rockcliff” or the “Company”) (TSX.V: RCU) (FRANKFURT: RO0, WKN: A142TR) is pleased to announce that an airborne drone magnetometer survey has been completed at the Company’s high grade Laguna Gold Property, Snow Lake, Manitoba.  The survey has identified the Laguna Gold Mine Trend, a minimum 6 kilometre long, structurally complex geological environment associated with known surface-exposed structurally controlled gold bearing quartz stockwork systems.  The Laguna Gold Property hosts the former high-grade Laguna gold mine, Manitoba’s first and highest grade gold mine and is part of the Company’s Snow Lake Project.  The Snow Lake Project is one of the highest grade precious and base metals property portfolios in North America. The Snow Lake Project is located in the prolific Flin Flon-Snow Lake mining camp which has had over a 100 year history in mining of high grade precious and base metals.

Ken Lapierre President & CEO stated "the airborne drone magnetometer survey successfully identified the Laguna Gold Mine Trend, a six kilometre long by 200 metre wide structurally complex geological trend. The Laguna Gold Mine Trend hosts multiple, surface-exposed, high grade gold-bearing quartz vein stockwork systems which are associated with sub-parallel subsidiary fault splays east of a major regional NE-SW trending thrust fault known as the Crowduck Bay Fault.  The high grade gold bearing quartz vein stockworks are located along high-strain zones on or near the contact with partially exposed folded quartz-feldspar-porphyry intrusions.  The potential for the discovery of additional gold bearing quartz vein stockworks within the Laguna Gold Mine Trend is considered excellent and represents the priority target at the Laguna Gold Property.  Additional surveys including VLF and IP geophysical surveys across the Laguna Gold Mine Trend are nearing completion and results will be released in the coming weeks.”

About the Laguna Gold Mine, Manitoba’s First and Highest Grade Gold Mine

The Laguna Gold Property hosts the Laguna gold mine, Manitoba’s first and highest grade former gold mine located in the Flin Flon-Snow Lake mining camp. Historical, intermittent gold mining between 1916 and 1939 produced over 60,000 ounces of high grade gold grading approximately 19.0 g/t.  The Laguna gold mine’s infrastructure consists of a reclaimed and covered three compartment vertical shaft to 381 metres and 8 levels totalling over 3 kilometres of underground drift and stope development. The Laguna Gold Property now includes 28 contiguous mining claims totalling 3,501 hectares covering a minimum 6 kilometres of prospective strike length of the Laguna Gold Mine Trend. The Laguna Gold Property is strategically located near an existing 2,150 tonne per day, presently non-operational, gold mill in Snow Lake, Manitoba.

The gold mineralization on the Laguna Gold Property is metallogenically controlled by subsidiary thrust faults attributed to the major regional Crowduck Bay Fault which crosses the entire length of the Laguna Gold Property. The gold-rich quartz veining and stockwork systems along the northwest limb of the Herb Lake Syncline typically occur where the subsidiary faults intersect quartz-feldspar and biotite porphryry stocks that intrude Missi Group sedimentary and volcanic rocks. Quartz, iron carbonate-albite-sericite alteration commonly overprint peak regional metamorphic assemblages within gold bearing vein margins. Mineralization in quartz and surrounding quartz stockwork wall rock consists of pyrite, arsenopyrite, chalcopyrite, sphalerite, galena, pyrrhotite, native gold and telluride.

Pursuant to its option agreement Rockcliff can earn a 100% interest in the Laguna Gold Property. Please refer to the Company’s news release dated September 12, 2016 for specific terms of the option agreement.

State-of-the-Art Airborne Drone Magnetometer Survey

A total of 1,120 kilometres of tightly spaced lines between 25 metre and 50 metre spacing was completed at the Laguna Gold Property by A.I.R. Inc. based in Flin Flon, Manitoba. The low flying Unmanned Aerial Vehicle (UAV) is a state-of-the-art Canadian designed and built helicopter style UAV which slings a potassium magnetic sensor underneath. Helicopters offer many advantages over other kinds of UAVs: Vertical Take-off and Launch, highest aerodynamic efficiency in forward flight as well as the best size vs payload vs flight time available. A GPS guided autopilot coupled with ground elevation data allows it to fly accurate survey lines that hug the terrain. With the implementation of a UAV over conventional ground and airborne surveys, users can now economically fly extremely tightly spaced lines with high density ground sampling distances without the need for line cutting. It is now possible to resolve individual magnetic anomalies that were previously indistinguishable when surveyed using conventional ground and airborne surveys, a perfect solution for structurally controlled gold exploration targets like that at the Laguna Gold Property. Ultimately, magnetic surveys done from a UAV deliver higher quality magnetic data at a decreased cost with a reduced environmental footprint.

About Rockcliff

Rockcliff is a Canadian resource exploration company focused on consolidation of the highest grade unmined precious and base metal mines/deposits in the prolific Flin Flon – Snow Lake greenstone belt specifically centered on Snow Lake, Manitoba. The Company’s Snow Lake Project, totalling in excess of 45,000 collective hectares is located in and around the Snow Lake mining camp.  The Snow Lake Project hosts the highest grade unmined NI 43-101 compliant copper deposits (the gold-rich Talbot copper deposit and the Rail copper deposit) and the highest grade unmined historical zinc deposits (the Lon zinc deposit, the Bur zinc deposit, the Morgan zinc deposit and the down dip continuation of the Pen zinc deposit).  The Snow Lake Project also includes Manitoba’s first and highest grade former Laguna gold mine, the high grade SLG gold property, the high grade DSN gold property and a Net Smelter Royalty (NSR) on the Tower property (the high grade T-1 copper deposit).  Near Leaf Rapids, north of Snow Lake, Rockcliff owns the near surface high grade MacBride zinc deposit.  Additionally, Rockcliff owns a NI 43-101 compliant zinc-silver deposit (the Shihan deposit) in Ontario and a royalty on two gold properties in Colombia, South America.
