Toronto, Ontario--(Newsfile Corp. - June 17, 2021) - Rockcliff Metals Corporation (CSE: RCLF) (OTCQB: RKCLF) ("Rockcliff" or the "Company") is pleased to announce the commencement of the Company's multi-phased Q3 and Q4 exploration program on several of its high priority targets. This multi-phased, $2.5 million fully funded exploration program, will include over 7,500 metres of drilling scheduled to begin in August. Drilling will focus on two priority targets - the TGR NI-PGE Prospect discovered in 2020 at the Company's Tower Property (see April 30, 2020 press release) and the historical high-grade Copperman Cu-Zn Deposit. 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. The Flin Flon-Snow Lake greenstone belt ("Belt") is the largest Paleoproterozoic volcanogenic massive sulphide ("VMS") district in the world and is best known for its prolific high-grade VMS metal endowment and almost 100 years of continuous production from over 30 mines.

Don Christie President and CEO commented, "exploration is an integral part of the operating strategy of a junior resource company and in our case a necessary complement to the extensive project development work we have carried out over the past 12 months on our portfolio of high-grade deposits. In the current commodity price environment, we must remain focused on the timely execution of our strategic objectives and look forward to providing our shareholders with positive developments on both our exploration and development initiatives over the remainder of 2021".

TGR Ni-PGE Prospect, Tower Property: Planned 4 to 6 holes, 1500 metres.

Four to six drill holes totalling 1,500 metres are planned 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.

Copperman Cu-Zn Deposit and Nearby Anomalies, Copperman Property: Planned 12 to14 holes, 6,000 metres.

Twelve to fourteen drill holes totalling 6,000 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.

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 potential anomalies with VMS upside in preparation of a planned drill program in early 2022.

DC Zone, Lon Property: Line cutting and surface geophysical TDEM survey.

The DC Zone is a mineralized surface outcrop associated with widespread VMS alteration and historical grab samples from trace up to 6% zinc. Historical surface geophysics identified a buried 600-metre-long geophysical anomaly below the surface mineralization. The purpose of the program is to pin point the location of the historical DC anomaly in preparation of a planned drill program in early 2022.
