Toronto, ON – December 20, 2017 – Rockcliff Metals Corporation (“Rockcliff“ or the “Company”) (TSX.V: RCLF) (FRANKFURT: RO0, WKN: A2H60G) is pleased to announce the completion of a first phase ten-hole step out drill program totalling 3,250 metres on the Company’s Bur Zinc property. The Bur Zinc property which hosts the historical high grade Volcanogenic Massive Sulphide (VMS) Bur zinc deposit is part of the Company’s Manitoba property portfolio. Rockcliff’s drilling was concentrated in an 800 metres long area southwest of the historical Bur zinc deposit below encouraging results from previous limited drilling. The Bur Zinc property is strategically located approximately 22 kilometres by road from Hudbay Minerals Inc.’s (“Hudbay”, HBM: TSX; NYSE) copper-zinc concentrator centered in the Snow Lake mining camp within the prolific Flin Flon-Snow Lake greenstone belt located in central Manitoba.
Significant highlights of Rockcliff’s first phase step out drill program are detailed below.
- Hole 007 yielded 7.2% ZnEq across 4.9 metres including 10.9% ZnEq across 2.9 metres
- Hole 005 yielded 6.8% ZnEq across 4.3 metres including 16.9% ZnEq across 1.0 metres
- Hole 002 yielded 5.9% ZnEq across 6.9 metres including 9.1% ZnEq across 2.4 metres
Rockcliff’s President and CEO Ken Lapierre commented, “Rockcliff’s first phase step out drill program was successful in identifying significant VMS mineralization adjacent to and southwest of the known limits of the historical Bur zinc deposit. Each drill hole intersected what is termed the Bur VMS horizon, a potential 8,000 metres long mineralized horizon that hosts the high-grade Bur zinc deposit. Largely untested by a systematic drill program outside of the Bur zinc deposit area, the potential to identify additional resources along this important horizon is considered excellent and will be the focus of upcoming drill programs on the Bur Zinc property.”
Significant assays from Rockcliff’s first phase step out drill program are tabled below.
Additional drill hole information from Rockcliff’s step out drill program is highlighted below.
A report was prepared on the Bur zinc property in 2007. Rockcliff is treating the estimate of mineral resources in the Bur Deposit Report as a “historical estimate” under NI 43-101 and not as a current mineral resource.
Historical estimates of grade and tonnage given in this press release are viewed as reliable and relevant based on the information and methods used at the time. The NI 43-101 Bur Deposit Report prepared for Hudbay in 2007 was prepared in compliance with resource definitions under NI 43-101 but must be considered only as historic resources as neither Rockcliff nor its Qualified Persons have done sufficient work to classify the historic estimate as a current mineral resource under current mineral resource or mineral reserve terminology and are not treating the historic estimate as a current mineral resource. The historic resource should not be relied upon. Additional work including surface geophysics, drilling and bore hole geophysics will need to be completed to upgrade the historical resource to current.
The Bur zinc deposit is a stratiform, distal, massive sulphide deposit that occurs within a narrow turbidite assemblage of interbedded metagreywacke, metasiltstone and graphitic meta-argillite in a basinal area situated between two granitic intrusions. The northeast striking deposit dips 60-70 degrees northwest, ranges from <0.3 metres up to 5 metres thick with a known lateral extent of approximately 4,500 metres. Historical drilling encountered disseminated, semi-massive and massive sulphide mineralization below overburden to a vertical depth of 950 metres. Mineralization consists of sphalerite, chalcopyrite, pyrrhotite, pyrite, galena and arsenopyrite. The Bur zinc deposit contains up to 20% felsic or cherty nodules consisting of wall rock and late quartz fragments displaying a brecciated texture to the mineralization. The Bur zinc deposit remains open in all directions.
Rockcliff can earn a 100% interest in the Bur Zinc Property from Hudbay. Please refer to Rockcliff’s news release dated September 26, 2016 for specific terms of the option agreement.
Quality Control and Quality Assurance
Samples of half core were packaged and shipped directly from Rockcliff’s field office to TSL Laboratories (TSL), 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 analysis 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.
Ken Lapierre P.Geo., President and CEO 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.
About Rockcliff Metals Corporation
On November 1, 2017 Rockcliff Copper Corporation changed its name to Rockcliff Metals Corporation. The change of name more accurately reflects the polymetallic nature of the Company’s high-grade VMS (copper, gold, zinc, silver) properties and its portfolio of primary lode gold properties.
Rockcliff is a Canadian resource exploration company focused on the discovery, advancement and consolidation of a portfolio of the highest grade, undeveloped metal deposits in the prolific Flin Flon – Snow Lake greenstone belt located in central Manitoba. The Company’s current portfolio of projects, totalling in excess of 45,000 hectares, is located in and around the Snow Lake mining camp and hosts some of the highest grade undeveloped NI 43-101 compliant copper deposits (the gold-rich Talbot copper deposit and the Rail copper deposit), and some of the highest grade undeveloped historical zinc deposits (the Lon zinc deposit, the Bur zinc deposit, the Morgan zinc deposit and the down dip continuation of the Pen zinc deposit). The Company’s properties also include Manitoba’s first and highest grade former lode gold producer (Laguna Gold property), four additional gold-rich properties (SLG Gold property, DSN Gold property, Berry Creek Gold property and Lucky Jack Gold property), a Net Smelter Royalty on the Tower property (the T-1 copper deposit) and the optioned near surface high grade MacBride zinc deposit located north of Snow Lake near Leaf Rapids, Manitoba.
