RCU021-005 had no significant mineralization, (m) = meters represent the interpreted true thickness,% = percentage, g / t = grams per tonne, * CuEq = equivalent value of copper used US $ 3.25 / pound of copper, US $ 1.25 / pound of zinc, US $ 1,750 / ounce of gold, and US $ 22 / ounce of silver. CuEq = Cu content% + (Zn content% X Zn price per pound / Cu price per pound) + (Au content g / t X Au price per gram / Cu price per tonne) X 100 + (Ag content g / t X Ag price per gram / price Cu per tonne) X 100. No process recovery or smelter creditors have been included in the calculation. Numbers may not add up due to rounding.

Rockcliff Interim President and CEO Don Christie commented, “The Phase 1 exploration drilling at Copperman has been extremely successful. It intersected significant, thick, high grade copper-zinc mineralization. 200 meters vertically encountered disseminated, semi-massive and massive chalcopyrite and sphalerite sulphides in multiple lenses up to 10 meters thick. The mineralization remains open in all directions and is exposed at the surface in historic trenches. A phase 2 drilling program scheduled for early January will attempt to extend the mineralized footprint as well as test several nearby undrilled geophysical anomalies. The Copperman property remains an exploration drilling priority for Rockcliff which is strategically located near existing infrastructure, including an operational mill and tailings pond.

To date, a total of 22 holes have been completed totaling 4,241 meters targeting in and around the historic Copperman deposit. Holes RCU021-12 to RCU021-022 are being analyzed or are currently divided and sampled. The results will be communicated as soon as they are received by the analysis laboratory.

Quality control and quality assurance

Half-core samples were packaged and shipped directly from the Rockcliff core facility in Snow Lake to ALS Canada Ltd. (ALS), in Thunder Bay, Ontario. ALS is a Canadian analytical laboratory and is accredited according to ISO / IEC 17025. Each bagged core sample has been dried, 70% crushed passing 10 mesh and a 250 g pulp is pulped at 85% passing 150 mesh for dosage. A 0.5 g cut is taken from each paste for base metal analyzes and leached in a multi-acid (total) digestion, then analyzed for copper, lead, zinc and silver by spectroscopy of inductively coupled plasma atomic emission. Gold concentrations are determined by fire assay using a 30 g load followed by atomic absorption finish. Samples above the upper limit of detection (3000 ppb) are reanalyzed by gravimetric fire assay using a load of 1 test ton. Rockcliff has inserted blanks and certified standards into the sample stream to ensure laboratory 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 the Canadian regulatory requirements set out in NI 43-101, has read and approved the scientific and technical information which forms the basis of the disclosure contained in this release press.
