Rockcliff Announces Commencement of a New Preliminary Economic Assessment of Tower and Rail

Toronto, Ontario--(Newsfile Corp. - July 14, 2021) - Rockcliff Metals Corporation (CSE: RCLF) (OTCQB: RKCLF) ("Rockcliff" or the "Company") is pleased to announce the commencement of a new NI 43-101 Preliminary Economic Assessment ("PEA") for the sequential development of the Company's 100% owned Tower and Rail projects. The Company filed an initial PEA for the combined projects on January 25, 2021. The purpose of this new PEA is to incorporate the results of an independent desk-top study of the Tower project completed in May of this year. The study concluded that by employing a more traditional alternative mining method, the Company could potentially materially reduce pre-production capital costs at Tower thereby improving the overall economics of the project. The Company believes that this alternative mining method, with the corresponding reduction in pre-production capital requirements, can also be employed at the Rail project. The Board of Rockcliff approved the commissioning of the new PEA for Tower and Rail to confirm the positive impact of the alternative mining method on the overall economics of the combined projects.

Management believes that being able to materially reduce pre-production capital costs at Tower and Rail is essential for the success of the first mining project to be developed by Rockcliff. This potential reduction in development capital, in combination with the competitive operating costs established in the desk-top study, should provide compelling economics for both the Tower and Rail projects. The sequential development of these two high-grade deposits, based upon projected daily mining rates, will result in a combined life-of-mine designed to meet investor requirements arising from commodity price cyclicality.

Don Christie, President & CEO commented, "I believe approaching this new PEA with a fresh perspective that utilizes a more traditional mine design is exactly what is required to reduce both development capex and operating risk while maximizing shareholder returns from the mining of our high-grade, steeply dipping, narrow vein deposits. Permitting on both the Tower and Rail projects is well advanced and it is Rockcliff's intention to fast-track the development of both Tower and Rail to take advantage of what is viewed by the Company as a strong and sustainable copper market. We look forward to providing investors with the results of the PEA combining both Tower and Rail by the end of Q3."
