RT MINERALS CORP. (“RTM”) TO ACQUIRE 100 SQUARE KILOMETRES OF MINERAL CLAIMS

CONTIGUOUS TO LINK-CATHARINE RLDZ PROPERTY, ONTARIO, BY ACQUISITION OF

CATHARINE GOLD INC. RESULTING IN CHANGE OF CONTROL OF RTM

Vancouver, B.C. – March 24, 2021 – RT Minerals Corp. (TSXV: RTM) (OTC Pink: RTMFF) (the “ Company”

or “RT Minerals” or “RTM”) is pleased to announce that it has entered into an arm’s -length agreement

with Mr. Ryan Kalt and Calgary-based Kalt Industries Ltd. to acquire all of the outstanding common shares

of Catharine Gold Inc. (“Catharine Gold”). Catharine Gold is a privately-held exploration company based

in Vancouver, British Columbia which owns the mineral rights to approximately 100 sq uare kilometres

(24,536 acres) of mineral properties which commence contiguous to the border of RTM’s Link -Catharine

property and which extend throughout six townships in northern Ontario, Canada. The mineral properties

controlled by Catharine Gold are situated approximately 22 km southeast of Kirkland Lake, Ontario and

extend intermittently and generally south, east and northeast immediately from RTM’s current Link -

Catharine property boundary for up to about 20 km, as well as ranging between 7 km to 21 km south of

the Cadillac Larder Lake Break (“CLLB”). The Catharine Gold property holdings are host to a large area

covering a southwestern section of the prospective Abitibi greenstone belt south and sub-parallel to the

CLLB. At least six known gold and base metal occurrences, local structural features as well as favourable

geologic package, known to host gold and base metal mineralization, occurs within licenses controlled by

Catharine Gold. From west to east the Catharine Gold property holdings cover portions of the contact-

point of the Round Lake Batholith and granodiorite suite extending into mafic and intermediate volcanics

to felsic volcanics.

Mr. Donald (Dan) M. Clark, Chairman and President of RT Minerals, states: “The combination of the 100

square kilometre favourable geologic package and land position held by Catharine Gold has the potential

for RT Minerals to be one of the largest mineral right owners within the Abitibi greenstone belt of northern

Ontario and Quebec. This underexplored portion of the belt is an important, immediately-adjacent major

expansion to RTM’s significant gold discovery in this area on its 100% optioned Link -Catharine property

where values of up to 8m at 9.43 g/t Au were encountered in near-surface drilling in late-2020. This drilling

intersected an overall area of intermittent gold values of approximately 130m wide by 100m in length and

90m in depth during November and December of 2020 (see RTM news releases dated November 11, 2020

and December 1, 2020). Furthermore, the forward-addition of Mr. Kalt to the board of directors will bring

additional financial and mineral management expertise to the Company to further advance RTM and

expand our exploration efforts within the 100 square kilometre land package to be controlled by RTM”.
