NEWS RELEASE

RT MINERALS CORP. ANNOUNCES DRILLING UNDERWAY AT LINK-CATHARINE GOLD PROPERTY,

KIRKLAND LAKE, ONTARIO AND UPDATES DRILL HOLE CA-21-01

Vancouver, B.C. – April 6, 2021 – RT Minerals Corp. (TSXV: RTM) (OTC Pink: RTMFF) (the “ Company” or

“RTM”) is pleased to announce that drilling at RTM’s Link-Catharine Gold Property is now underway, with

the first drill core having been pulled during the course of the Easter long-weekend.

The first phase of drill-bit exploration for 2021 consists of a proposed seven hole drill program. The first

drillhole, CA-21-01 (see details below), is now at 225m and testing an anomaly outlined by a 3D Distributed

Array IP geophysical survey completed for the Company in January 2021 (the “ Link-Catharine 3D IP

Survey”). The Link-Catharine 3D IP Survey was conducted by Canadian Exploration Services Ltd., and is

available for interested parties to view by visiting:

Update on Drillhole CA-21-01

CA-21-01 has intersected intermittent quartz veining ranging between several centimeters and up to 1m

wide with 3 % to 5% sulphides throughout the interval from approximately 123m to 136m . This 13m

interval is within green carbonates and a porphyritic dyke. In addition, a second 45m interval between

180m to 225m has intersected like sulphides with numerous narrow quartz stringers within a green

carbonate host unit. Due to the favourable host unit and the presence of quartz with 3% to 5% sulphides

over this 45m interval, Hole CA -21-01 is continuing to drill to depth. The above section s of drill core

stratigraphically aligns with the geophysical IP target (Target “A”) delineated by the Link-Catharine 3D IP

Survey.

The current drill program is designed, in part, to follow-up on a significant gold discovery of three separate

sub-parallel / en -echelon gold sections encountered and disclosed by RTM during the Company’s drill

program in the fourth quarter of 2020 (see news release dated December 1, 2020). The Q4 2020 drilling

encountered intermittent gold mineralization within an area approximately 130m west to east, 100m

north to south and to a depth of 140m. Importantly, the potential for further mineralization is open in all

directions. The current drill program and/or follow-on phases may also test additional targets on the Link-

Catharine Gold Project, as delineated by RTM subsequent to the fourth quarter.

Highlights of the Q4 2020 drill program consisted of near-surface gold intercepts of up to 8m of 9.43 g/t

Au (CA 20-01), 1.0 m of 3.07 g/t Au (CA 20-02), 0.49 m of 7.43 g/t Au (CA 20-03), 0.05m of 6.56 g/t Au (CA

20-04), 6.9m of 2.25 g/t Au (CA 20 -05). The above noted higher-grade intervals were contained within

areas of intermittent gold mineralization over 35m to 54m intervals.

None of the above Q4 2020 drill program holes tested the anomalies subsequently identified during the

January 2021 geophysical program , and drillhole CA-21-01 is now testing one such newly-identified IP

anomaly. The drill core observed today in the 13m section and the 45m section of current hole CA-21-01

is similar to the green carbonate host unit with quartz veining and sulphides observed in CA-20-01 drilled

in Q4 2020.

For complete drillhole tables and intercepts to date from the Link-Catharine Gold P roperty, see the

Company’s December 1, 2020 press release. True width of the gold mineralization from the 2020 drilling

has not been determined at this time.

The Link-Catharine Gold Property is located approximately 25 km southeast of Kirkland Lake, Ontario,

within an infrastructure-rich area. The project is the subject of an earn-in option agreement, as announced

by the Company on September 29, 2020, under which RTM may earn up to 100% interest, subject to a 2%

NSR.
