Toronto, Ontario--(Newsfile Corp. - May 5, 2022) - Rockcliff Metals Corporation (CSE: RCLF) (OTCQB: RKCLF) ("Rockcliff" or the "Company") is pleased to announce the completion of it phase 2 drill program at the historical Last Hurrah Zone at its 100% owned Freebeth Property. The Last Hurrah Zone is defined as a near surface, steeply dipping, high grade volcanogenic massive sulphide ("VMS") lens that is open at depth, to the north and partially to the south. The Freebeth Property is part Rockcliff's extensive property portfolio within the Snow Lake mining camp(see Figure 1). It is strategically located within the world class Flin Flon - Snow Lake Greenstone Belt, the largest Paleoproterozoic VMS District in the world.
Significant drill results from the 14 hole-3,168 metres phase two drill program include:
LH22-011: 2.9% CuEq across 1.7 m including 6.7% CuEq across 0.4 mLH22-012: 7.2% CuEq across 1.7 m including 14.5% CuEq across 0.5 mLH22-013: 2.1% CuEq across 2.7 m including 4.1% CuEq across 0.6 mLH22-014: 3.8% CuEq across 4.2 m including 5.5% CuEq across 1.5 mLH22-016: 6.2% CuEq across 1.5 m including 9.5% CuEq across 0.4 mLH22-017: 4.3% CuEq across 3.0 m including 7.7% CuEq across 0.2 mLH22-022: 1.1% CuEq across 5.8 m including 2.3% CuEq across 2.0 m
Rockcliff's Interim President and CEO Ken Lapierre commented, "Our phase two drill program has now identified continuity of VMS mineralization across a strike length of over 350 metres and to depths of up to 300 metres vertical. The Last Hurrah Zone is strategically located just down the road from our 100% owned recently drilled high grade Copperman VMS Deposit. Both properties are less than 50 kilometres by highway to the active Snow Lake mining camp where Hudbay controls two processing facilities. The Last Hurrah Zone is part of our exploration efforts in the region to identify high priority targets near existing mining infrastructure. Rockcliff remains focused on target and resource generation on its extensive portfolio of grass roots to PEA level properties that are strategically located within the world class Snow Lake mining camp."

Quality Control and Quality Assurance
Samples of half core from the Last Hurrah Zone drill program 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.
