Toronto, Ontario--(Newsfile Corp. - December 15, 2021) - Rockcliff Metals Corporation (CSE: RCLF) (OTCQB: RKCLF) ("Rockcliff" or the "Company") is pleased to announce additional high-grade volcanogenic massive sulphide ("VMS") drill results from its completed Phase 1 drill program at the Company's 100% owned Copperman Property.

Significant interpreted true thicknesses and grades are highlighted below and include:

  • RCU21-006: 3.4% CuEq across 3.0 m including 4.7% CuEq across 1.0 m
  • RCU21-009: 4.9% CuEq across 6.0 m including 6.6% CuEq across 4.0 m
  • RCU21-010: 6.6% CuEq across 10.0 m including 13.5%CuEq across 4.0 m
  • RCU21-011: 2.4% CuEq across 5.0 m including 4.5% CuEq across 1.4 m

Significant interpreted true thicknesses and grades from drill core assays are summarized below. Please note that holes RCU21-001 to RCU21-004 were press released on November 24, 2021.

RCU021-005 did not have significant mineralization, (m) = metres represent interpreted true thickness, % = percentage, g/t = grams per tonne, *CuEq = copper equivalent value used US$3.25/pound copper, US$1.25/pound zinc, US$1750/ troy ounce gold and US$22 /per ounce silver. 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.

Rockcliff's Interim President and CEO Don Christie commented, "Phase 1 exploration drilling at Copperman has been extremely successful. It has intersected significant, thick, high-grade copper-zinc mineralization. Drilling across a strike length of 130 metres and to depths of up to 200 metres vertical have encountered disseminated, semi-massive and massive chalcopyrite and sphalerite sulphides in multiple lenses of up to 10 metres thick. Mineralization remains open in all directions and is exposed at surface in historical trenches. A Phase 2 drill program planned in early January will attempt to expand the mineralized footprint as well as test several nearby undrilled geophysical anomalies. The Copperman Property remains a top exploration drill priority for Rockcliff that is strategically located near existing infrastructure including an operational mill and tailings facility."

Quality Control and Quality Assurance

Samples of half core 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. 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.

Ken Lapierre P.Geo., VP Exploration of Rockcliff, a Qualified Person in accordance with Canadian regulatory requirements as set out in NI 43-101, has read and approved the scientific and technical information that forms the basis for the disclosure contained in this press release.
