RT MINERALS ANNOUNCES UPDATE AND SUMMARY ON NORDICA PGE PROPERTY , ONTARIO

Vancouver, B.C. –December 19, 2023 – RT Minerals Corp. (TSXV: RTM) (OTC Pink: RTMFF) (the

“Company” or “RTM”) announces update and summary of its 100% owned Nordica property, Ontario,

Canada.

MINERALOGICAL REVIEW AND EXPLORATION MODELS – NORDICA PROPERTY , ONTARIO

At present most of the worldwide supply and mineral resources of plaƟnum and palladium and the

associated elements are obtained from mines within four major layered Archean igneous intrusions.

These are the Bushveld Complex in South Africa, the SƟllwater Complex in the U.S.A., the Great Dyke in

Zimbabwe, and the Norilsk/Talnakh Complexes in Russia. These layered intrusions consist of rocks which

cooled slowly from molten magma, deep within the earth.

The resultant layering also controls the distribuƟon of the ore deposits. Chromite (chromium rich oxide),

ilmenite (Ɵtanium-rich oxide) and plaƟnum group minerals normally occur in associaƟon with the more

mafic parts, whereas magneƟte (iron oxide), cassiterite (Ɵn oxide), zircon (zirconium silicate), etc., are

generally restricted to the more silicic parts.

From Ɵme to Ɵme in this process the magma may vary a liƩle in composiƟon and layers of the

chromium-rich mineral (chromite) will form, to give the rock known as chromiƟte. Layers of chromiƟte

are frequent in these intrusions. Less frequently, the variaƟon in magma composiƟon is a layer which is

rich in the sulfides of iron, nickel, copper, together with the sulfides, arsenides, tellurides and alloys of

the plaƟnum group elements (PGE) forming the plaƟnum group minerals.

As to the Bushveld complex PGM minerals consist of PlaƟnum (Pt), Palladium(Pd), osmium, iridium,

rhodium, ruthenium as well as vast quanƟƟes of iron (Fe), Ɵn (Ti), chromium(Cr), Ɵtanium (Ti) and

vanadium (V).

In Canada, the most prolific PGM (primarily Pd) group mine is the Lac des Iles mine, located ~120 road

kms north of Thunder Bay, Ontario. The total Lac Des Illes Mineral Resources and Reserves are

approximately 91 million metric tons (Mt) with 3E grade of 2.42 g/t Pd, Pt, Au Eq (Implats 6/30/2022

Mineral Resource and Reserve Statement). It is hosted by the ~2.7 Ga Archean Lac des Iles intrusive

complex in the southern Wabigoon sub province of the Superior province of Canada. The ore at Lac Des

Illes is characterized by low concentraƟons of sulfide (typically less than 3 vol %) and high Pd contents

and has Ni, Cu and Co mineralizaƟon intermiƩently within the complex.

At Lac Des Iles chromiƟte is not as prevalent as it is in the principal mines of the Archean Bushveld

complex of South Africa, where chromium grades can average 40% Cr in associaƟon with PlaƟnum group

ores in close proximity or at different levels of the layered units.

RT MINERALS – NORDICA PROPERTY , ONTARIO

At RTM’s Nordica property chromiƟte (Chromite) has been encountered at surface outcrops with grades

up to 17.59% Cr and is found in two separate outcrops up to 2.7 km apart, prospecƟvely on strike.

Associated with the Chromite are Pt values up to 0.234 g/t and Pd values of up to 1.188 g/t.

The Nordica property is located approximately 40 minutes driving Ɵme by paved and dirt road from

Kirkland Lake, Ontario, and has approved drill permits in place. The property is contained within the

Kinojevis assemblage of northeast trending volcanic sequences sandwiched between the Kasba and

Watabeag Lake batholiths. Locally the volcanic succession under the property is a westward grading

sequence of mafic-intermediate tholeiitic meta volcanic rocks (MNDM files OFR 6042).

Within the Kinojevis assemblage, the Nordica property contains over 75% of the known Nordica

ultramafic layered Intrusion. The Nordica intrusion is a mafic and ultramafic layered intrusive complex

located at the southeast margin of the Kasba Lake granodiorite pluton in northern Nordica Township.

Historical exploration programs carried out by previous explorers revealed several distinct lithologies

contained within this intrusion. The Lithologies include Troctolite, Hornblendite and highly magnetic

cumulate Olivine Gabbronorite (leucocratic Gabbro) which contain individual massive chromatite

(chromite) units. Magmatic layering is evident in the Troctolite sequences. The mafic-ultramafic suite

is intrusive into the Kinojevis assemblage and has been cut by the granodiorites of the Watabeag

Batholith.

The Hornblendites locally contain up to 8.0% sulphides and the leucocratic gabbro contain 2.0%

disseminated sulphides. The Chromatite units vary in thickness from 1.0 - 3.0 meters and individual

massive units can contain up to 17.59 % chromite.

Most of the area is covered by glacial overburden. Government geophysical surveys (MNDM files

M82219, M82218, M82031, M82047) strongly suggest that the entire intrusive complex could extend

in a northwest – southeast direction for 4.0+ kms (Figure2). It is currently known to be 250+ m wide

(southeast edge of the Intrusion near original past discovery outcrop) and scattered isolated outcrops

of gabbro extend the intrusive for at least 1.3 kms in width to the northwest (MNDM files 20006208,

20000004200 Figure 2).

The depth of the Instusive is presently unknown, however historic diamond drill holes NW-98-1 and

NW-98-2 encountered at least 100 meters of ultramafic intrusive assemblage prior to encountering

Granodiorite Watabeag intrusive and diabase dykes. Drilling from the opposite direction of these

holes will provide more data on the depth component of the ultramafic at the southeastern end.

Drilling is recommended on specific targets of the ~4.0 km by 1.3 km Nordica Intrusive with the

objective to expand the nickel, copper, platinum, palladium, Chromium, , cobalt, selenium, vanadium

and titanium mineralization currently known to exist within portions of the Nordica complex.

In addition, future drilling would target new cumulative ultramafic intrusive bodies within the

strongest magnetic signatures identified within the prospect. Drilling is subject to financing.

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

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

Minerals Projects. The Nordica Property is an early stage exploraƟon prospect and has no resources or

reserves. The summary of the Bushveld and Lac Des Iles Intrusive complexes are noted as opƟmal

examples of Archean Igneous Intrusives which have resources and reserves with varying styles of PGE

mineralizaƟon.

Historical drill intercepts contained herein are not true widths. True widths of the historical drilling

cannot be determined at this Ɵme.

Past and current mineralized chip, trench and drill core samples are from two separate sample areas

situated approximately 2.7 kms apart which are associated with the Nordica Intrusive complex.

All assaying by RT Minerals Corp has been carried out by Swaslabs of Kirkland Lake, Ontario, and have

been previously released by the Company without comparaƟve rock type analysis of both past and

current mineralizaƟon and rock units, which have now been included herein.
