Rockcliff Intersects High Grade Mineralization at Copperman with 4.0% CuEq Across 2.9 Metres Including 18.3% CuEq Across 0.5 Metres
Toronto, March 7, 2022 - Rockcliff Metals Corp. (CSE: RCLF) (OTCQB: RKCLF) ("Rockcliff" or the "Company") is pleased to announce additional high-grade volcanogenic massive sulphide ("VMS") drill results from its ongoing phase two drill program at its 100% owned Copperman Property. The Copperman Property hosts the historical unmined Copperman VMS Deposit and is within the Snow Lake Mining Camp that is strategically located within the world class Flin Flon - Snow Lake Greenstone Belt, the largest Paleoproterozoic VMS District in the world.
Rockcliff's Interim President and CEO Ken Lapierre commented, "Copperman drill results within and proximal to the historical Copperman VMS Deposit continue to intersect multiple high grade VMS intervals across 150 metres of strike, to depths of 250 metres and remains open in all directions. Additional nearby geophysical targets will also be tested for their significance. Rockcliff remains committed to target generation, discovery and growth of our existing deposits that are favorably located within the world class Snow Lake Mining camp."

Quality Control and Quality Assurance
Samples of half core from the Copperman Property were packaged and shipped directly from Rockcliff's core facility in Snow Lake to ALS Canada Ltd. (ALS), in Thunder Bay, Ontario. ALS is a Canadian assay laboratory and is accredited under ISO/IEC 17025. Each bagged core sample was dried, crushed to 70% passing 10 mesh and a 250g pulp is pulverized to 85% passing 150 mesh for assaying. Once processed, samples are shipped from the preparation lab to their accredited analytical facility in North Vancouver, BC. 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 inductively coupled plasma atomic emission spectroscopy. Gold concentrations are determined by fire assay using a 30g charge followed by an atomic absorption finish. Samples greater than the upper detection limit (3000 ppb) are reanalyzed using fire assay gravimetric using a 1 assay Ton charge. Rockcliff inserted certified blanks and standards in the sample stream to ensure lab integrity. Rockcliff has no relationship with ALS other than ALS being a service provider to the Company.
Ken Lapierre P.Geo., Interim President & CEO and VP Exploration of Rockcliff, a Qualified Person in accordance with Canadian regulatory requirements as set out in NI 43-101, has read and approved the scientific and technical information that forms the basis for the disclosure contained in this press release.
