February 22, 2022

Toronto, ON – February 22, 2022 – Rockcliff Metals Corporation (“Rockcliff” or the “Company”) (CSE: RCLF) (OTCQB: RKCLF) is pleased to announce the filing on SEDAR of its Preliminary Economic Assessment (“PEA”) for the Company’s 100% owned Tower and Rail Project (“the Project”), located in the Flin Flon-Snow Lake Greenstone Belt in the Snow Lake area of central Manitoba.  Results of the PEA were previously disclosed in the Company’s news released dated February 1, 2022. 

The PEA, titled "Preliminary Economic Assessment Tower and Rail Project" (the “Technical Report”), was prepared in accordance with the requirements of National Instrument 43-101 by A-Z Mining Professionals Ltd. and has an effective date of February 1, 2022. 

The robust PEA is highlighted by a C$81.0 million initial capital investment generating an after tax NPV8 of $128.6 million and IRR of 67%.  The short 12-month payback period from a 9.5-year Life of Mine (“LOM”) generates an approximate 12,000 CuEq tonnes per year at an all-in sustaining cost of US$2.46 per pound copper.  Both deposits remain open with a real possibility of adding Mineral Resources to extend the LOM.
