Rockcliff Identifies High Grade Gold Veins at Laguna

TORONTO, ONTARIO--(Marketwired - Oct. 26, 2016) - Rockcliff Copper Corporation ("Rockcliff" or the "Company") (TSX VENTURE:RCU) is very pleased to announce that the Company's exploration program has identified visible gold and high grade gold mineralization from known historic surface quartz veins at its Laguna Gold property. Additionally, the Company has discovered a gold bearing quartz vein stockwork system with a minimum surface strike length of 300 metres and a true thickness of up to 5 metres. Rockcliff has an option to earn a 100% interest in the Laguna Gold property which hosts the former high grade Laguna gold mine and multiple quartz veins exposed at surface. The property is strategically located 20 kilometres from a fully functional, non-operating, 2,150 tonne per day gold mill facility in Snow Lake, MB.

Exploration at the Laguna property identified surface quartz veins yielding high grade gold mineralization. Of immediate interest is a quartz rich stockwork system traced intermittently for over 300 metres along strike with a true thickness of up to 5 metres. Termed the "007 quartz vein", it is open to expansion in all directions with grab samples assaying from trace to 43.3 g/t gold, 1.2 g/t to 118.6 g/t silver and trace to 6.2% zinc. Additional historic veins (newly termed #001 vein to #006 vein) were located with grab samples assaying from trace gold up to 699.2 g/t (20.4 ounces per tonne) gold. The veins ranged between 0.2 metres up to 5.0 metres in width and were traced up to 1.0 kilometres along strike and visible gold was observed in outcrop. A total of 50 grab samples taken by Rockcliff are tabulated below. Quartz veins 3 and 4 returned no significant gold values in the samples assayed to date.

Rockcliff's follow-up plans will include data compilation, surface geophysics (an induced polarization survey) followed by a first phase drill program. With multiple high grade, gold-rich, quartz veins throughout the Laguna property and no diamond drilling completed since the 1940s, the 2016-2017 exploration program is the first systematic, scientific exploration program on the property in over 70 years.

The Laguna property hosts the Laguna gold mine, the highest grade former gold mine in the Flin Flon-Snow Lake mining camps. Historical, intermittent gold mining from the Laguna vein between 1916 and 1939 of approximately 101,012 tonnes averaged 20.5 g/t (0.60opt) and produced over 60,000 ounces of gold. The Laguna gold mine infrastructure consists of a three compartment vertical shaft to 381 meters and 8 levels totalling over 3.0 kilometres of underground drift and stope development. The Laguna vein remains open along strike and at depth. Exploration has identified quartz veins #001 to #007 located proximal to the Laguna vein, all of which show significant potential for advancement. The Laguna property includes 15 contiguous mining claims totalling 920 hectares and is located approximately 20 kilometres southeast of the Town of Snow Lake, MB.

The gold mineralization on the Laguna property is metallogenically controlled by subsidiary thrust faults attributed to the major Crowduck Bay Fault which crosses the entire length of the property over a distance of 3.5 kilometres. The gold-rich quartz veining along the northwest limb of the Herb Lake Syncline typically occurs where the subsidiary faults intersect quartz-feldspar and biotite porphyry stocks that intrude Missi Group sedimentary and volcanic rocks. Quartz-iron carbonate-albite-sericite alteration commonly overprints peak regional metamorphic assemblages within auriferous vein margins. Mineralization in quartz and surrounding wall rock consists of pyrite, arsenopyrite, chalcopyrite, sphalerite, galena, pyrrhotite, native gold and telluride. Typical gangue minerals include tourmaline and fuchsite.

Rock samples were taken in the field, packaged and shipped directly from Rockcliff's field office to TSL Laboratories (TSL), Saskatoon, SK. TSL is a Canadian assay laboratory and is accredited under ISO/IEC 17025. Each bagged rock sample was dried, crushed to 70% passing 10 mesh and a 250g pulp was pulverized to 95% passing 150 mesh for assaying. A 0.5g cut was taken from each pulp for base metal analysis (if needed) and leached in a multi acid (total) digestion and then analyzed for copper, lead, zinc and silver by atomic absorption. Gold concentrations were determined by fire assay using a 30g charge followed by fire assay gravimetric an atomic absorption finish. Samples greater than an upper detection limit (3000 ppb) were reanalyzed using a 1 AT charge. Rockcliff inserted certified blanks and standards in the sample stream to ensure lab integrity.
