FOR IMMEDIATE RELEASE Rockcliff Metals Now Largest Landholder in Snow Lake, Manitoba Toronto, ON – Sept 12, 2018 – Rockcliff Metals Corporation (“Rockcliff” or the “Company”) (TSX.V: RCLF) (FRANKFURT: RO0, WKN: A2H60G) today announced that it has acquired through map staking a 100% interest in 2 separate land packages and now controls approximately 169,000 hectares making it the largest landholder in the Snow Lake portion of the world-class Flin Flon – Snow Lake greenstone belt (“Belt”). Rockcliff’s President & CEO Ken Lapierre stated: “The Belt has been home to over 30 base metal mines and 8 gold mines. Having worked there for over 13 years, we felt the time was right to acquire key land positions in an evolving new mining camp south-southeast of Snow Lake. We acquired the VMS #1 Property and the VMS #2 Property for their potential to host significant new high-grade mineral discoveries. With land covering 80 km of collective strike length, we are now in a position of beginning the compilation of all available data and are planning to complete an airborne geophysical survey with the ultimate goal of identifying drill targets. We will also continue to look at strategic opportunities to monetize Rockcliff’s extensive base metal and gold assets and advance our portfolio of high-grade properties in the camp.” Please review the image on the following page which highlights the strategic location of the VMS #1 Property and the VMS #2 Property. About the newly acquired VMS #1 Property and VMS #2 Property The VMS #1 Property and the VMS #2 Property (the “Properties”) host a total of 8 Mineral Exploration Licenses (MEL) totalling over 115,452 hectares and are located in what is termed the Snow Lake South Emerging Mining Camp. The Properties strategically cover an underexplored area hosting the southeast extension of the world-class and prolific Belt. A minimum of 7 known base metal deposits from 250,000 tonnes up to 6.0 million tonnes in size are located along strike of both Properties and host the same juvenile arc rocks associated with all of the VMS mines and deposits in the Belt. The Properties are covered by a thin veneer of limestone progressing from nothing up to 100 metres thick in a southward progression. This cover impeeded historic exploration efforts but advances have present geophysical surveys allow a “windowing effect” through the limestone cover so metal bearing targets can be identified. Rockcliff now controls 100% of the Properties with no outstanding royalties and has unfettered access to explore and discover mineralization within the property limits. Yearly escalating expenditures must be completed and submitted to the Government to maintain the property in good standing. The first year’s exploration commitment is $144,315 to maintain the MEL claims. A winter airborne geophysical program is planned on the Properties in 2019 to define drill targets that warrant follow-up.
