Rockcliff Identifies Near Surface High-Grade Copper and Zinc Mineralization at the Freebeth Property Including 5.28% CuEq Across 2.30 Metres and 4.00% CuEq Across 4.70 Metres

Sudbury, Ontario--(Newsfile Corp. - May 21, 2020) - Rockcliff Metals Corporation (CSE: RCLF) (FSE: RO0) (WKN: A2H60G) ("Rockcliff" or the "Company") is pleased to announce the completion of its phase one drill program at the Company's 100% owned Freebeth Property located in central Manitoba. The drill program was successful in locating and identifying the historical Last Hurrah Zone ("LHZ"). The Freebeth Property is strategically located within trucking distance to the Company's leased processing and tailings facility.

Rockcliff's President and CEO Alistair Ross commented: "Drilling on the Freebeth Property has demonstrated excellent potential to host significant near surface copper-zinc mineralization. The LHZ is associated with a 1.4 kilometre long airborne geophysical anomaly and is located only 3.5 kilometres south-east of the past producing Spruce Point copper-zinc mine. Drilling has clearly identified a zone of high-grade copper and zinc mineralization that remains open along strike and at depth. The property has excellent infrastructure with an all-weather paved highway to our leased mill located approximately 125 kilometres to the east. The LHZ now ranks as a high priority advanced exploration target and we look forward to determining the extent of the known mineralization with future exploration and drilling."

Significant down the hole assays from Rockcliff's phase one drill program are summarized below.

(m) = metres represents down the hole widths as true widths are not currently known, % = percentage, g/t = grams per tonne, *CuEq = zinc equivalent value used US$3.00/pound copper, US$1.10/pound zinc, US$1350/ troy ounce gold ($43.40/gram) and US$16.50 /per ounce silver ($0.53/gram). CuEq = Cu grade % + (Zn grade % X Zn price per lb / Cu price per pound) + (Au grade g/t X Au price per gram / Cu price per tonne) X 100 + (Ag grade g/t X Ag price per gram / Cu price per tonne) X 100. No process recoveries or smelter payables were included in the calculation. The numbers may not add up due to rounding. Holes LH20-001 and LH20-002 were abandoned. LH20-003, 007 and 010 did not intersect significant mineralization proximal to the Last Hurrah Zone. FW20-001, 002 did not intersect significant mineralization related to the West Target. FNT20-001, 002 did not intersect significant mineralization related to the North Target. LHE20-001 intersected significant barren sulfides in the footwall rocks of the Last Hurrah Zone.

Quality Control and Quality Assurance

Samples of half core were packaged and shipped directly from Rockcliff's field office to TSL Laboratories (TSL), in Saskatoon, Saskatchewan. TSL 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 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 the 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.
