Rockcliff Provides Update on 2021 Exploration Program

August 9, 2021

Toronto, ON – August 9, 2021 – Rockcliff Metals Corporation (“Rockcliff” or the “Company”) (CSE: RCLF, OTCQB: RKCLF) is pleased to provide an update on its 2021 exploration program initially disclosed in the Company’s June 17, 2021 news release. The $2.5 million fully funded drill program is now permitted to begin at the Copperman Property where +5,000 metres of drilling is planned to commence this month.  

Don Christie President and CEO commented, “Extreme wildfire activity in the Snow Lake area resulted in the Manitoba Government restricting exploration activities in the region including the recently announced drill program at our Tower TGR Ni-PGE Prospect as well as our planned airborne flying. Our Copperman drill permit has just been reinstated with drilling to commence shortly. While we are disappointed that our other exploration programs have been curtailed for now, the safety of our field crew and contractors remains our top priority.  We intend to resume our additional exploration as soon as possible once all other permits are reinstated”.

The Company’s drill program is focussed on two priority targets.  The first being the Copperman property where two high priority geophysical targets remain untested as well as the historical high-grade Copperman deposit. The second priority target is the TGR NI-PGE Prospect discovered in 2020 at the Company’s Tower Property (see April 30, 2020 news release).  Both of these projects are 100% owned by Rockcliff. In addition to the drill program, the Company will complete over 2,200 kilometres of airborne geophysical flying and geological and ground geophysical surveys scheduled for September, weather permitting.

Copperman Cu-Zn Deposit and Nearby Anomalies, Copperman Property: Planned 10 holes, +5,000 metres.

Approximately ten holes totalling 5,000 metres are planned. The drilling will test the historical Copperman Cu-Zn Deposit and several nearby untested surface geophysical anomalies. The Copperman Cu-Zn Deposit was discovered in 1927 by surface trenching. Mineralization is associated with at least three high-grade lenses. Historical near surface drill results documented in the Manitoba Mineral Deposits Database; Deposit # M63J/12-004 included:

  • 8.3 metres grading 3.62% copper, 2.59% zinc
  • 9.7 metres grading 1.69% copper, 5.05% zinc
  • 7.0 metres grading 8.09% copper, 7.29% zinc
  • 7.6 metres grading 1.85% copper, 4.58% zinc

Historical drill results cannot be relied upon for a basis for future drill results.

TGR Ni-PGE Prospect, Tower Property: Planned 4 holes, 1,000 metres.

Four holes totalling 1,000 metres are planned (pending lifting of fire restriction) at the high-grade TGR Ni-PGE Prospect to follow up on  the discovery hole and additonal drilling completed in 2020. The TGR Ni-PGE discovery hole was initially tested for potential VMS mineralization associated with a large interpreted VMS target located 600 metres south of the Company’s copper-rich Tower Deposit. The 2020 discovery hole intersected significant nickel-PGE mineralization at a down hole depth of 244.8 metres.  
Nickel Equivalent (“NiEq”) metals values used in the April 30, 2020 press release were US$6.10/pound nickel, US$1,450/ounce palladium, US$865/ounce platinum, US$6,000/ounce rhodium, US$1,675/ounce Iridium, US$400/ounce osmium and US$280/ounce ruthenium. No process recoveries or smelter payables were included in the calculation. True thickness is not presently known at this time.

SLS #1-#5 Properties: Airborne VTEM survey.

The favourable VMS geology within the Company’s 100% owned SLS properties are buried under a thin limestone cover. The SLS properties represent a significant and strategic land package of underexplored VMS potential located in the southern half of the prolific Belt that hosts the Flin Flon and Snow Lake VMS mining camps.  A total of over 2,200 kilometres of airborne VTEM flying will be completed over specific strategic areas of the properties that represent high priority areas interpreted as VMS conductive trends.  The purpose of the program will be to isolate anomalies with potential VMS upside in preparation of a planned drill program in early 2022.

Bucko Mill

Management has recently completed a review of milling options available to Rockcliff. The results of this internal review have led the Company to conclude that the Bucko Mill no longer represents the best option available to Rockcliff for the potential processing of ore from the Company’s multiple deposits and as such the Company has decided not to exercise its option to lease the Bucko Mill from CaNickel Mining Limited. There has been a significant increase in the projected costs necessary to refurbish the Bucko Mill, convert from nickel to copper/zinc concentrate production and expand the existing tailings management facilities. In addition, there will be material transportation costs necessary to ship ore from the Company’s deposits to the Bucko Mill.  Management has determined at this time, that the capital cost and milling capacity of currently available, portable on-site milling facilities has the potential to provide a superior  milling solution for Rockcliff’s multiple deposits. As an owned, not leased asset, the portable mill represents better value-for-money and provides the Company with more long-term milling certainty on an acceptable life-of-mine basis which is not available to the Company under the current terms of the Bucko Mill lease agreement. This milling solution is being incorporated into the Company’s Preliminary Economic Assessment of the combined Tower and Rail deposits (please refer to the Company’s news release dated July 14, 2021).  Moving forward with this alternative potential milling solution is in alignment with Rockcliff’s strategy of fit-for-purpose infrastructure and specifically tailored mining approaches that are amenable to the multiple locations and unique physical characteristics of the Company’s portfolio of high-grade deposits being considered for development.
