RT Minerals Corp. Acquires Additional Rare Earth and Nickel-Chromium-Cobalt Properties in Northeastern Ontario

Nordica Property (Cu, Ni, Co, Cr, Pd)

The Nordica property is comprised of 34 claims in Nordica Township that cover the ultramafic layered Nordica Intrusive Complex in the Abitibi Greenstone Belt, within the Superior Province, 60 km southeast of Timmins, Ontario (Figure 1). The Company acquired 14 of the claims through map staking (MLAS, Ontario) and 20 of the claims (the "Vendor Claims") by way of a purchase and sale agreement (the "Agreement") with an arms length vendor for consideration of 300,000 common shares of the Company and a 2% Net Smelter Return ("NSR") royalty on the Vendor Claims as well as any claims that the Company has acquired within a 2 km area of interest surrounding the Vendor Claims, of which 0.8% NSR may be purchased for $2,500,000 at any time. The Agreement is subject to the approval of the TSX Venture Exchange.

The Nordica property is prospective for copper ("Cu"), nickel ("Ni"), cobalt ("Co"), chromium ("Cr"), and palladium ("Pd") mineralization. Previous exploration activity on the Nordica property has encountered Cu grading up to 0.292% (rock-grab samples), Ni up to 0.24% in drill core over 1.0 m, Co up to 614ppm (outcrop), Cr up to 17.7% (grab-rock sample) and Pd up to 1.2ppb (outcrop chip sample and drill core interval over 1.0m) (MNDM files OFR 6102). The property covers approximately 75% of the ultramafic layered intrusion which is currently inferred to be approximately 4.0 km long, 250 m wide and 100m deep (MNDM files 20000008666/2000113735) (Figure 2).

Galna / Moody Property (Cu, Ni, Co, Cr)

The Galna / Moody property is comprised of four separate claim blocks totalling 24 cells in the Galna and Moody Townships, Ontario that the Company acquired a 100% royalty free interest by map staking (MLAS, Ontario).

The Galna-Moody property is located 35 km east of Iroquois Falls, Ontario. The claim blocks are prospective for Cu, Ni, Co and Cr contained within individual peridotite ultramafic cumulate intrusive complexes that are intruded into the meta volcanic sequences of the Abitibi Greenstone Belt. The intrusive lenses are characterized by strong magnetic signatures (MNDM files 42h02SE0001, M81908) (Figure 3).

Previous exploration activities have identified up to 0.35% Ni and 0.57% Cr in peridotite grab-rock samples from within individual peridotite lenses up to 150 m in thickness (MNDM files 42H02SE0001, 42A16SW0081).

Kendrey Property (REE)

The Kendry property is comprised of 32 claims that the Company acquired a 100% royalty free interest by map staking (MLAS, Ontario) in the Kendrey and Colquhoun Townships located 14 km southeast of Smooth Rock Falls, Ontario.

The Kendrey property covers what appears to be a large, inferred carbonatite complex that is prospective for rare earth elements, specifically niobium. The intrusive is approximately 2.8 km wide and 2.7 km long. It is positioned along a southeastern extensional splay fault belonging to the Kapuskasing Structural Trend. The magnetic signature is very similar to several documented carbonatite complexes that contain an internal low magnetic central core surrounded by a highly magnetic circular outer ring (MNDM files PO 452, M82813, M82824). The intrusive is bounded to the east by a large north-south trending fault (Figures 4 and 5).

The exploration programs contemplated on the three new property acquisitions are eligible under the Federal Government of Canada flow-through shares and critical minerals exploration tax credit programs, subject to acceptance. Work permitting programs are being submitted on seven of the properties for 2023 and 2024 exploration. Exploration plans are subject to financing.

Ireland Property (Rare Earth Element - Case Batholith) is a royalty free 52 claim block covering an inferred carbonatite complex (the "Ireland Complex") located in Ireland Township, 45 km northeast of Smooth Rock Falls, Ontario. The Ireland Complex is 100% owned by RTM and is approximately 4.0 km long, 2.8 km wide, oval shaped and is positioned along a southern extensional splay fault contained within the Kapuskasing Structural Trend. The Kapuskasing Structural Trend contains several well documented carbonatite complexes that contain Niobium, Iron, Titanium and Rare Earth Element resources within various assemblages of carbonatite rocks.

Case Batholith Group 1 (Rare Earth Element) consists of 90 claims covering the Case Batholith centered on Heighington Township, 85 km northeast of Cochrane, Ontario. The Case Batholith properties are 100% owned and royalty free.
