Rockcliff Intersects High-Grade Copper Below the Rail Deposit 7.04% CuEq Across 3.6 Metres and 10.78% CuEq Across 2.44 Metres

TORONTO, September 26, 2019 - Rockcliff Metals Corp. ("Rockcliff" or the "Company") (CSE:RCLF)(FRANKFURT:RO0)(WKN:A2H60G) is pleased to announce that initial Phase 1 drilling has intersected high-grade copper mineralization associated with a large geophysical anomaly extending immediately below the 100% owned high-grade Rail Deposit. The Rail drill program, which will consist of a minimum 10,000 metres of drilling, is part of the Company's fully funded, 16-month drill campaign. Phase 1 of this extensive drill program is focussed on enhancing several advanced stage deposits, including the Rail Deposit. Rockcliff is the largest development and exploration junior landholder in the Flin Flon-Snow Lake greenstone belt, the most extensive Paleoproterozoic Volcanogenic Massive Sulphide ("VMS") district (copper, gold, zinc, silver) in the world.

Rockcliff's initial drill results from the Rail Deposit intersected high-grade intervals summarized in the table below:

(m) = metres represents down the hole thickness as true thicknesses are not currently known, % = percentage, g/t = grams per tonne, *CuEq = copper equivalent value used: US$3.00/pound copper, US1300/ troy ounce gold, US$1.15/pound zinc and US$20 /per ounce silver, 100% metal recoveries were applied, CuEq calculation is: = Cu grade + (Zn grade%/100*2204.6 x Zn price) + (Au grade/32.15/1000 x Au price) + (Ag grade/32.15/1000 x Ag price)/Cu price/20. The numbers may not add up due to rounding.

Rockcliff's President and CEO Alistair Ross commented: "To have the first holes hit massive sulphide intercepts exactly where the geophysical anomaly inferred them to be, boosts our confidence in our understanding of the geology of the Rail Deposit and across the region. To have these holes also hit high-grade copper combined with meaningful gold grades is an auspicious beginning to our pursuit of becoming Manitoba's next copper producer. Along with our Talbot and Tower deposits, these results increase the prospect of a third, near surface, deposit at Rail, giving the Company additional optionality when it comes to advancing one or more of our properties to a development stage."

Significant individual down hole assays from RL19-062 and RL19-064 are summarized in the table below:

(m) = metres represents down the hole thickness as true thicknesses are not currently known, % = percentage, g/t = grams per tonne, *CuEq = copper equivalent value used: US$3.00/pound copper, US1300/ troy ounce gold, US$1.15/pound zinc and US$20 /per ounce silver, 100% metal recoveries were applied, CuEq calculation is: = Cu grade + (Zn grade%/100*2204.6 x Zn price) + (Au grade/32.15/1000 x Au price) + (Ag grade/32.15/1000 x Ag price)/Cu price/20. The numbers may not add up due to rounding.

Assays are pending for holes RL19-063 and RL19-065.

The Rail Deposit: National Instrument 43-101 Indicated Resource ("NI 43-101 Compliant Resource")

Rockcliff filed an initial NI 43-101 Compliant Resource on the Rail Deposit on December 20, 2010. The report entitled "Mineral Resource Evaluation, Rail Polymetallic Sulphide Deposit, Snow Lake, Manitoba", dated December 19, 2010 (the "Rail Deposit Report"), was prepared by Sébastien Bernier, M. Sc., P.Geo, and Dominic Chartier, P.Geo.,, qualified persons under National Instrument 43-101, on behalf of SRK Consulting (Canada) Inc. ("SRK"). The Rail Deposit Report is available for viewing on the SEDAR profile for Rockcliff Resources Inc. ("Rockcliff Resources"), the predecessor of the Company, at www.sedar.com.

The Mineral Resource Statement for the Rail Deposit is reported at a cut-off grade of 2.0 percent copper. The statement includes metal grade for copper, zinc, gold and silver but not lead because this metal is present at near detection limits. The Mineral Resource Statement for the Rail Deposit is summarized in Table 1.

Table 1: Mineral Resource Statement*, Rail Polymetallic Sulphide Deposit,

Manitoba, SRK Consulting, November 4, 2010

*Reported at a cut-off grade of 2.0 percent copper. Cut-off grade is based on copper price of US$3.00 per pound and a metallurgical recovery of eighty percent, without considering revenues from other metals. All figures rounded to reflect the relative accuracy of the estimates. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

The mineral resources are reported at a cut-off grade of 2.0 per cent copper to reflect "the reasonable prospects" for economic extraction. SRK considers the Rail Deposit to be amenable to extraction using underground mining methods. The Mineral Resources Statement for the Rail Deposit presented in Table 1 are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves. The Indicated Mineral Resource for the Rail Deposit was classified according to the CIM Definition Standards for Mineral Resources and Mineral Reserves (December 2005) by Sebastien Bernier, P.Geo (APGO#1847), an appropriate independent person for the purpose of National Instrument 43-101.

Quality Control and Quality Assurance

Samples of half core were packaged and shipped directly from Rockcliff's field office to TSL Laboratories (TSL), in 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 analyses 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., Vice-President, Exploration of Rockcliff, a Qualified Person in accordance with Canadian regulatory requirements as set out in NI 43-101, has reviewed and approved the scientific and technical information that forms the basis for the disclosure contained in this press release.
