RT MINERALS CORP. ANNOUNCES ACQUISITION OF THE KENOGAMING-PHARAND

NICKEL-CHROMIUM-COBALT CLAIM BLOCKS ON THE NORTHERN SWAYZE GREENSTONE BELT,

SOUTHWEST OF TIMMINS, ONTARIO

Vancouver, B.C. – March 2, 2023 – RT Minerals Corp. (TSXV: RTM) (OTC Pink: RTMFF) (the “Company”

or “RTM”) announces that it has both acquired by map staking (MLAS) and entered into a third-party

agreement to acquire 100% royalty-free interest in an aggregate 32 claims in the Kenogaming and Pharand

Townships (the “Properties”) in the Northern Swayze Greenstone Belt, located within the Abitibi sub-

province of the Superior Province, southwest of Timmins, Ontario (Figure 1).

Figure 1: Location map of Kenogaming and Pharand properties

The Properties are located within the Hanrahan assemblage which is confined to the southeastern part of

the Northern Swayze Greenstone Belt. The Hanrahan assemblage consists predominantly of calc-alkaline

intermediate and felsic volcanic rocks that have been intruded by extensive ultramafic and gabbroic sills

(cumulate- textured ultramafic bodies). The cumulate ultramafic bodies are the specific targets

comprising the Kenogaming, Pharand I and Pharand II prospects (Figure 2). The ultramafic cumulates are

fine to medium grained massive rocks that are strongly magnetic, locally serpentinized and talcose, and

may contain fuchsite mica.

Figure 2: Northern Swayze Greenstone Belt

Differentiation within the ultramafic bodies is observed as serpentine units grade upwards from olivine

orthocumulates into gabbroic zones and spinifex- textured pyroxenites. Rare spherical structures filled

with serpentine and sulphides suggest evidence for an extrusive origin for some of the massive cumulate

- textured ultramafic rocks.

Throughout the Swayze Greenstone Belt, several nickel occurrences are associated with the cumulate -

textured ultramafic rocks (MNDM files R297). The documentation of large ultramafic bodies with nickel

mineralization in western Kenogaming Township is a strong indication of good potential for Komatiite -

hosted nickel mineralization similar to the nickel discoveries in Crawford and Reid Townships near

Timmins, Ontario (MNDM files 20000018167).

Nickel, chromium, cobalt and platinum group elements in assay results are of specific interest for the

Kenogaming - Pharand claims.

The Kenogaming prospect consists of 8 claims located in eastern Kenogaming Township. In 1979, after

completion of a localized magnetic/HLEM geophysical survey, Amax Minerals tested a strong magnetic

anomaly with diamond drill hole KEN-#1 (Figure 3). This 184.5m long hole 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. The entire hole encountered cumulate ultramafic assemblages

(MNDM files 42A04NW8557).

Figure 3: Kenogaming Holes

In 1997, a follow up drill hole JOE-ANNE SALO J-1-97 was drilled to a depth of 119m, 42m to the northeast

of KEN-#1 on an additional localized magnetic target from a geophysical survey covering the same

magnetic anomaly. Beginning at 23 m from surface, the hole encountered 78m of cumulate ultramafics

with seven selected and intermittent one metre assay values (whole rock analysis) ranging from 0.168%

Ni and up to 0.328% Ni, 0.17% Cr and 165 ppm Co (MNDM files 42A04NW2003) (Figure 3). From 39m to

84m, eight select and intermittent core samples were analysed by plasma scan which outlined eight one

metre sections at the maximum capability of the scan at +999 ppm Ni.

Subsequent to this 1997 drilling, the regional Ontario Geological Survey Total Intensity

Magnetic/Electromagnetic program was flown over Kenogaming and Pharand Townships (MNDM-

M81379). This airborne survey outlined the main magnetic anomaly (56500nT+) ultramafic cumulate

intrusive body to be approximately 700m wide and 1,000m long (MNDM-M81379, Figure 3). When

combining the two historic holes, it is evident that the intrusive contains semi-continuous nickel,

chromium and cobalt mineralization beginning at 15m and extending to a current depth of 184.5m. The

intrusive may extend another 1.0 km to the east and is open to continuation at depth.

The Company’s claims cover two large ultramafic intrusive prospects, Pharand I (16 claims) and Pharand

II (14 claims) within Pharand Township. The RTM claim blocks cover intense magnetic signatures

(56500nT+) believed to represent cumulate ultramafic intrusive bodies.

Future drilling is warranted on the Kenogaming, Pharand I and Pharand II prospects with the objective to

expand the historical nickel, chromium, and cobalt mineralization within the Kenogaming intrusive. In

addition, future drilling subject to financing would target new cumulate ultramafic intrusive bodies within

the strongest magnetic signatures identified on the Pharand I and II prospects. The exploration activities

contemplated on the Properties are eligible under the Federal Government of Canada Flow-Through

Shares and Critical Minerals Exploration Tax Credit programs, subject to acceptance.

The Company acquired 16 of the Kenogaming-Pharand claims directly by map staking and 16 of the claims

will be acquired pursuant to a broader property purchase agreement that was disclosed by news release

on February 28, 2023. The Company agreed to issue 250,000 post-consolidation common shares (for

more information on the Share Consolidation, please see news release dated February 6, 2023) and pay

$4,100 to acquire 100% interest, subject to certain retained royalties, in 78 claim blocks located in

northern Ontario. Closing of the transaction is subject to the successful completion of the Share

Consolidation, a concurrent post-consolidation financing of $450,000, and the approval of the TSX

Venture Exchange.
