Rockcliff Identifies Near Surface High-Grade Copper and Zinc Mineralization at the Copperman Property Including 4.35% CuEq Across 6.00 Metres and 3.33% CuEq Across 8.3 Metres

 

 

 

 

 

Rockcliff Metals Corporation (CSE: RCLF) (OTCQB: RKCLF) is pleased to announce high-grade near surface assay drill results from its phase one drill program at the Company’s 100% owned Copperman Property located in the Snow Lake mining camp in Manitoba.

 

Significant interpreted true thickness highlights from the first four holes include:

  • RCU21-001: 7.1 m grading 3.06% CuEq including 5.0 m grading 4.00% CuEq
  • RCU21-002: 6.0 m grading 4.35% CuEq including 4.0 m grading 5.89% CuEq
  • RCU21-003: 8.3 m grading 3.33% CuEq including 5.3 m grading 4.62% CuEq
  • RCU21-004: 5.0 m grading 2.64% CuEq including 3.0 m grading 3.32% CuEq

 

Rockcliff’s Interim President and CEO Don Christie commented, “We are extremely pleased with these high-grade assay results from the initial drill holes at Copperman. The near-surface widths are also very encouraging and we hope the ongoing drill program continues to produce these types of impressive results. The fact that the high-grade zone of copper-zinc mineralization and several other lower grade zones are hosted in a classic bi-modal volcanic environment is a testament to the prospectivity of the property for volcanogenic massive sulphides (VMS). Several other near surface geophysical anomalies similar to the one that is associated with the historical Copperman Deposit are untested with significant upside potential.”

 

Significant true thickness drill core assays from Rockcliff’s phase one drill program are summarized below.

(m) = metres represents 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.

To-date, a total of 15 holes have been completed totalling 2,670 metres targeting the historical Copperman deposit have been completed. An additional 10 holes are planned.

 

Additional drill hole information is summarized below.

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 couple 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.
