Rockcliff Completes 51% Earn-in on Talbot Property, Reports Additional High-Grade Drill Results Including 10.15% CuEq Across 3.46 Metres

December 18, 2019

Toronto, ON – December 18, 2019 – Rockcliff Metals Corporation (“Rockcliff” or the “Company”) (CSE: RCLF) (FRANKFURT: RO0, WKN: A2H60G) is pleased to announce that is has completed all work required for the Company to earn a 51% ownership interest in the Talbot Property pursuant to the Company’s option agreement with Hudbay Minerals Inc. (“Hudbay”) dated April 14, 2014 (the “Option Agreement”). Rockcliff has delivered written notice to Hudbay advising Hudbay of the achievement of this milestone. In addition, the Company announces additional high-grade assay results from the Talbot Property of 4.04% Copper Equivalent (“CuEq”) across 11.13 metres including 10.5% CuEq across 3.46 metres.

  • The Talbot Property, one of Rockcliff’s core projects, is a gold-rich, copper asset. The Talbot deposit hosts a National Instrument 43-101 (“NI 43-101”) inferred mineral resource of 4.2 million tonnes at 1.6% Cu, 1.8 g/t Au, 1.4% Zn, 28 g/t Ag as disclosed in the Rockcliff press release dated January 19, 2018. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
  • To the best of knowledge of Rockcliff, the Talbot deposit constitutes one of the largest pre-production inferred resource estimates in the Flin Flon belt.  The Talbot deposit is located within trucking distance to the Company’s leased +1,000 tonnes per day mill and tailings facility. 

Rockcliff’s 51% Interest in Talbot

Highlights from the Talbot Property Option Agreement:

  • Rockcliff has incurred the $6.12 million in expenditures required to earn its 51% interest in the property;
  • Hudbay has a 24 month back-in right which expires in November of 2021.  The back-in right gives Hudbay the right to acquire an additional 2% ownership interest in the property, thereby raising their ownership stake to 51%, and resulting in Hudbay becoming the operator of the property;
  • If, as operator, Hudbay takes the property into production, Rockcliff could retain a minimum 35% carried interest in the property through life-of-mine;
  • If Hudbay does not exercise its back-in right, Rockcliff as operator could take the property into production and earn a minimum 65% interest in the property.

Rockcliff is the largest junior development and exploration landholder in the Flin Flon-Snow Lake greenstone belt, a region Rockcliff believes is the most extensive Paleoproterozoic Volcanogenic Massive Sulphide (“VMS”) district (copper, gold, zinc, silver) in the world.

Talbot Drill Results in 4.04% CuEq Across 11.13 Metres Including 10.5% CuEq Across 3.46 Metres

The latest round of drill results includes 4.04% CuEq across 11.13 metres including 10.5% CuEq across 3.46 metres.   The Talbot drill program has been designed to enhance the confidence of the existing Talbot deposit inferred resource within the main lens.  To-date, 19 holes totaling 11,669 metres have been completed (holes TB021-TB039). Holes TB033-TB039 have been submitted to the assay lab for analysis for copper, gold, zinc and silver. Holes TB021-TB025 assay results were pressed released on November 12, 2019 and filed on Sedar.

Significant down the hole assays from the Talbot drill program are tabled below:

m =metres represent down hole thickness as true thickness is not currently known, g/t = grams per tonne, CuEq** = copper equivalent values used: US$3.00 copper, US$1.20 zinc, US$1400 gold, US$22.00 silver. 100% metal recoveries were applied. 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.

Quality Control and Quality Assurance

Samples of half core were packaged and shipped directly from Rockcliff’s core facility in Snow Lake to TSL Laboratories (TSL), in Saskatoon, Saskatchewan.  TSL 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 95% 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 atomic absorption.  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 AT charge.  Rockcliff inserted certified blanks and standards in the sample stream to ensure lab integrity. Rockcliff has no relationship with TSL other than TSL being a service provider to the Company.
