Rockcliff Intersects Near Surface High Grade Zinc-Copper Mineralization at Bur Property Including 13.51% ZnEq Across 3.26 Metres and 15.64% ZnEq Across 1.94 Metres
Sudbury, Ontario--(Newsfile Corp. - May 7, 2020) - Rockcliff Metals Corporation (CSE: RCLF) (FSE: RO0) (WKN: A2H60G) ("Rockcliff" or the "Company") is pleased to announce the completion of its phase four drill program at the Company's Bur Property located in central Manitoba. The drill program was successful in identifying additional shallow, near surface, high-grade Zinc-Copper mineralization along strike of the historcial Bur Zinc-Copper Deposit. Rockcliff is presently earning a 100% interest in the Bur Property.
Rockcliff's President and CEO Alistair Ross commented: "Our phase four drill program has shown great promise in extending the known mineralization of the historical Bur Zinc-Copper Deposit. The drilling has identified shallow high-grade mineralization above 150 metres vertical over a distance of more than 500 metres in an underexplored area south of the high-grade deposit. We look forward to continuing to advance the property as we near our 100 % earn-in requirement of $3 million. Given our current copper focus, we are particularly interested in the number of copper assays over 2% in this area."
Significant down the hole assays from Rockcliff's phase four drill program are included in the following table:

(m) = metres represents down the hole widths as true widths are not currently known, % = percentage, g/t = grams per tonne, *ZnEq = zinc equivalent values used: US$1.10/pound zinc, US$3.00/pound copper, US$1350/ troy ounce gold ($43.40/gram) and US$16.50 /per ounce silver ($0.53/gram). ZnEq = Zn grade (%) + [Cu grade (%) X Cu price per lb / Zn price per pound] + [Pb grade (%) X Pb price per lb / Zn price per pound] + [Au grade (gpt) X Au price per gram / Zn price per tonne]X 100 + [Ag grade (gpt) X Ag price per gram / Zn 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 numbered RBU049, 51 and 61 did not return significant values.

A report was prepared on the Bur Property in 2007. Rockcliff is treating the estimate of mineral resources on the Bur Zinc-Copper Deposit Report as an "historical estimate" under NI 43-101 and not as a current mineral resource.
