High Grade Gold Identified at Snow Lake Project Summer Exploration Program to Commence

TORONTO, ONTARIO--(Marketwired - May 4, 2016) - Rockcliff Copper Corporation ("Rockcliff" or the "Company") (TSX VENTURE:RCU) is pleased to announce high gold grades from surface grab samples at its Dickstone North Property as part of its ongoing regional exploration program on its Snow Lake Project ("Project") located in central Manitoba. Grab sample results ranging from trace to as high as 21.2g/t gold were identified within a mineralized quartz vein system along a strike length of 140m. The quartz vein system is located in the vicinity of high priority airborne geophysical anomalies which remain unexplained. Also, a fully permitted, geological and geophysical exploration program will commence shortly on areas of the Project with high priority targets for VMS (copper, gold, zinc, silver) and gold mineralization. The Project is located within the world class Flin Flon-Snow Lake greenstone belt. The Project presently hosts several high grade VMS deposits rich in copper, gold, zinc and silver and numerous additional areas with potential for discovery.

At the 100% owned Dickstone North Property, high grade gold was identified in the vicinity of historical, overgrown, shallow trenches. A total of thirteen grab samples were analyzed and returned results ranging from trace to as high as 21.2g/t gold. Gold values are hosted within a quartz vein system up to 2.0m in width and traced for 140m cross-cutting a large porphyritic intrusion. Mineralization consists of chalcopyrite, arsenopyrite, pyrrhotite and pyrite. Two unexplained airborne VTEM anomalies are located south of the gold showing and additional exploration in this area is strongly warranted.

The fully permitted summer exploration program will focus on specific properties within the Project including the Dickstone North, Lon, Rail, Tramping and Talbot properties. Work will focus on geological and geophysical surveys over high priority areas prior to drilling. At Dickstone North, work will focus on the recently identified gold-rich quartz vein system and the nearby VTEM anomalies. At Lon, geological and geophysical surveys will be completed in the vicinity of the "DC Zone"; a surface outcrop exposure of 6.1% Zn (historic grab sample) located proximal to an untested 600m long, 13 channel DPEM conductor. At Rail, exploration will focus on a 4 km long "copper corridor" that hosts the Rail Deposit and several airborne anomalies on strike with the deposit. At Tramping, an untested buried circular airborne anomaly associated with favourable geology will be ground proofed. At Talbot, additional surface geophysics will be completed on areas proximal to the high grade Talbot Copper Deposit where previous work outlined potential areas with additional copper mineralization.

Ken Lapierre, President and CEO commented, "We look forward to advancing our new high grade gold system at the Dickstone North Property and continuing to advance our high grade copper assets within the Project. With a successful summer field season we look forward to a busy drill program this fall."

Quality Control and Quality Assurance

Samples of half core are packaged and shipped directly from Rockcliff's field office to TSL Laboratories (TSL), Saskatoon, Saskatchewan. TSL is a Canadian assay laboratory and is accredited under ISO/IEC 17025. Each bagged core sample is dried, crushed to 70% passing 10 mesh and a 250g pulp is pulverized to 95% passing 150 mesh for assaying. A 0.5g cut is taken from each pulp for base metal analyses and leached in a multi acid (total) digestion and then analyzed for copper, lead, zinc and silver by atomic absorption. Gold concentrations are determined by fire assay using a 30g charge followed by an atomic absorption finish. Samples greater than upper detection limit (3000 ppb) are reanalyzed using fire assay gravimetric using a 1 AT charge. Rockcliff inserted certified blanks and standards in the sample stream to ensure lab integrity. Rockcliff has no relationship with TSL other than TSL being a service provider to the Company.
