NEWS RELEASE

RT MINERALS CORP. STAKES 190 CLAIMS TO EXPAND ITS CASE BATHOLITH, ONTARIO, HOLDINGS

CONTIGUOUS TO POWER METALS CORP. AND BEYOND LITHIUM INC. PROPERTIES.

Vancouver, B.C. – July 20, 2023 – RT Minerals Corp. (TSXV: RTM) (OTC Pink: RTMFF) (the “Company” or “RTM”) is

pleased to announce that it has acquired by staking a further 190 claims (~4,000 Ha) within the Case Batholith

about 150 kms northeast of Timmins, Ontario, to expand RTM’s claim holdings in this area.

The newly staked RTM claims adjoin claims that are owned by Power Metals Corp., Beyond Lithium Inc., and

others, in this area of the Case Batholith. The Power Metals property contains a significant Lithium-Cesium

discovery at the southeastern end of the Case Batholith. This entire area of the southeastern portion of the Case

Batholith is now fully staked and forms a large contiguous block of claims for current and future exploration in this

part of Ontario, by the various owners.

These newly staked RTM claims are in addition to four Case Batholith properties 100% owned by RTM, located in

Agassiz Township (29 claims), Potter Township (51 claims), Seguin/Challies Township (14 claims) and Bragg

Township (19 claims) ; (Total 100% RTM Case Batholith area ~6,000 Ha / Figure 1).

Figure 1.

All of RTM claim blocks have been acquired on the basis of favourable geologic prospectivity for pegmatite units

and magnetic signatures resembling east - west trending pegmatitic dykes and laccolith structures contained

within the tonalite/granodiorite rock assemblages of the Case Batholith.

The Potter and Seguin/Challies prospects contain vast exposures of outcrop that have been identified on several

vintages of satellite photography. Live satellite views strongly suggest the occurrence of long linear pegmatitic

dykes and ovoid intrusives on the surface on these claims.

Qualified Person

The technical information contained in this news release has been reviewed and approved by Mr. Garry Clark,

P.Geo., a “Qualified Person” as defined in National Instrument 43-101 – Standards of Disclosure for

Mineral Projects. Rare Earth Element mineralization that exists on the Power Metal Corp. Case Batholith properties

is not known to exist on the Company’s properties in the Case Batholith area.

About RT Minerals Corp.

RTM is a junior exploration company listed on the TSX Venture Exchange under the symbol “RTM”. The Company

holds a 100% interest, largely royalty-free, in a portfolio of rare earth element, gold and base metal properties in

Ontario. The Company also holds an option to acquire a 100% interest in the Link-Catharine RLDZ gold property

located 22 km south-southeast of the town of Kirkland Lake, Ontario.

Nordica Property (Cu, Ni, Co, Cr, Pd) 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. Nordica is prospective for copper, nickel, cobalt, chromium, and palladium 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 and drill core over 3 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).

Kenogaming, Pharand I and Pharand II Properties (Ni, Cr, Co) consists of 38 claim blocks that are 100% owned

with 32 claims royalty free and 6 claims subject to a 2% NSR royalty. The properties are situated in Kenogaming

and Pharand Townships in the Northern Swayze Greenstone Belt, located within the Abitibi sub-province of the

Superior Province, southwest of Timmins, Ontario. The Properties are located within the Hanrahan assemblage

which is confined to the southeastern part of the Northern Swayze Greenstone Belt. Cumulate ultramafic bodies

are the specific targets comprising the Kenogaming, Pharand I and Pharand II prospects. In 1979, previous

operators tested a strong magnetic anomaly with a 184.5m long diamond drill hole, which intersected up to 0.25%

nickel in carbonated and serpentinized cumulate ultramafic with interbeds of chlorite and talc alteration over a

3.0m section at the bottom of the hole. Further drilling is warranted on the Kenogaming, Pharand I and Pharand II

prospects with the objective to expand the historical Ni, Cr, Co mineralization within the Kenogaming intrusive.

Ireland Property (Rare Earth Element) 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 and New 190 Claim Staking (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. The properties occur within the boundaries of the Case Batholith and are

specifically located in Heighington, Kenning, Sequin, and Case Townships. Five properties are situated 12 km north

of the Power Metals Case Lake lithium/cesium discovery in Steel Township. The 190 newly staked claims adjoin

Power Metals and Beyond Lithium land holdings located in the southeastern portion of the Case Batholith.

Case Batholith Group 2 (Rare Earth Element) consists of four properties (113 claim blocks) that are 100% owned

and certain of the claims are subject to a 2% NSR royalty, within the boundaries of the Case Batholith in northern

Ontario. The four properties are in Agassiz township (29 claims), Potter township (51 claims), Seguin/Challies

township (14 claims) and Bragg township (19 claims), Ontario. Substantially all the claim blocks have been acquired

based on magnetic signatures resembling east - west trending pegmatitic dykes and laccolith structures contained

within the tonalite/granodiorite rock assemblages of the Case Batholith.

Sheba-Michie-Alma (Cu, Ni , Co, Cr, Pt), Ontario, are as summarized above herein. Kendrey Property (Rare Earth

Element) consists of 32 claims in the Kendrey and Colquhoun Townships located 14 km southeast of Smooth Rock

Falls, Ontario that are 100% owned and royalty free. The property covers what appears to be a large, inferred

carbonatite complex that is prospective for rare earth elements, primarily 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.

Galna / Moody Property (Cu, Ni, Co, Cr) consists of four separate claim blocks totalling 24 cells in the Galna and

Moody Townships, located 35 km east of Iroquois Falls, Ontario. The Company acquired 100% interest in the

property by map staking. Timmins Property (Base Metals) is a royalty free 16-claim block located approximately 50

km southeast of Timmins, Ontario, and is 100% owned by RTM. The property features several mineralized fault

systems that suggest proximity to a base metal source.

Milligan Property (Gold) is a royalty free 16-claim block located approximately 75 km northeast of Timmins,

Ontario, and is 100% owned by RTM. Milligan Property (Gold) covers the southeast extension of the volcanic

stratigraphy hosting the Eastford Lake gold discovery of 142.2 g/t Au over 3.0 m announced by Explor Resources in

2009.

Blakelock Property (Gold) is a royalty free 9-claim block located approximately 75 km northeast of Cochrane,

Ontario, and is 100% owned by RTM. The property is host to a massive east-west trending magnetic high intrusive

complex that was subject to limited drilling in 1967.

Mcquibban Property (Gold) is a royalty free 19-claim block located approximately 50 km north of Cochrane,

Ontario, and is 100% owned by RTM. The property hosts a strong 3.0 km long east-west trending inferred oxide

facies banded iron formation, in which one historical drill hole encountered a gold mineralized interval of 5.47 g/t

Au over 1.2m.
