RT MINERALS CORP. ANNOUNCES ACQUISITION OF A NICKEL-CHROMIUM-COBALT-COPPER PROPERTY

WITHIN THE ABITIBI GREENSTONE BELT OF NORTHEASTERN ONTARIO

AND PROPOSED PRIVATE PLACEMENT

NOT FOR DISTRIBUTION TO UNITED STATES NEWS WIRE SERVICES OR FOR DISSEMINATION IN THE

UNITED STATES

Vancouver, B.C. – June 13, 2023 – RT Minerals Corp. (TSXV: RTM) (OTC Pink: RTMFF) (the “Company” or

“RTM”) announces that it has entered into an agreement (the “Agreement”) to acquire a 100% interest in

51 mineral claims (the “Property”) in Sheba Township in the Abitibi Greenstone belt, located within the

Superior Province, 70 km southeast of Timmins, Ontario (Figure 1) for consideration of $3,000 and 250,000

common shares of the Company. The Agreement is subject to the acceptance of the TSX Venture Exchange

(the “TSXV”).

The Property is divided into three blocks: Sheba North (23 claims), Sheba South (15 claims) and Sheba East

(13 claims). The blocks are prospective for copper (Cu), nickel (Ni), cobalt (Co), chromium (Cr), platinum

(Pt), and palladium (Pd) mineralization (MNDM files 42A02SE2019).

Previous exploration activities by other operators on the west border of the Sheba South block

encountered samples taken from outcrop containing 0.19% Cu, 0.14% Ni and 0.34% Cr. In addition to these

samples, further samples were historically taken within the same ultramafic Pyroxenite -peridotite

assemblages on the Sheba South block which returned highly anomalous Cu, Ni and Cr values from

outcrop. Whole rock analysis of these units appears substantiall y identical to the peridotites and

associated Ni mineralization that occurs in Langmuir Township, 36 km on trend to the northwest.

The pyroxenites-peridotites exhibit strong magnetic signatures and the Sheba North and Sheba East blocks

cover extensive geop hysical magnetic anomalies that are currently interpreted as peridotite intrusive

bodies within the volcanic stratigraphy of the Abitibi Greenstone belt. The Sheba East anomaly is shown

in Figures 2 and 3 (MNDM files M82050, M82049, M82031, M82032 and M82056).

In addition, geochemical soil surveys indicate that the Sheba East block is covered by widespread

anomalous Cu and Ni concentrations in soils (MNDM files 42-A02NE2002) (Figure 4).

The exploration programs contemplated on the three blocks are potentially eligible under the Federal

Government of Canada’s flow-through shares and Critical Minerals exploration tax credit programs. The

acquisition of the Sheba property expands the Company’s portfolio of 100% owned critical mineral and

gold exploration projects to 13. Work permitting programs have been submitted on 7 of the properties for

the 2023 and 2024 exploration years.

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

Proposed Private Placement

The Company proposes to undertake a non -brokered private placement (the “Offering”) to raise gross

proceeds of $100,000 through the sale of 1,000,000 units (each, a “Unit”) of the Company at a price of

$0.10 per Unit. Each Unit consists of one common share and one-half of a share purchase warrant, with

each whole warrant exercisable into one further common share at a price of $0.12 for a term of 12 months.

The warrants will be transferrable, and all securities issued will be subject to a statutory hold period of

four months and one day.

The proceeds from the Offering will be used for general working capital. The Offering is subject to the

approval of the TSXV.

A director of the Company will acquire securities under the Offering, which will be considered a "related

party transaction" as defined under Multilateral Instrument 61 -101 ("MI 61-101"). Such participation is

expected to be exempt from the formal valuation and minority shareholder approval requirements of MI

61-101.
