RT MINERALS CORP. FILES UPDATED NI 43-101 TECHNICAL REPORT ON NORWALK GOLD PROPERTY,

WAWA, ONTARIO

Vancouver, B.C. – July 15, 2020 – RT Minerals Corp. (TSX.V: RTM) (OTC Pink: RTMF D) (the “Company”)

announces that it has filed an Updated NI 43-101 Technical Report on SEDAR of its 100% owned Norwalk

gold property (the “Property”) located near Wawa, Ontario, and contiguous to the southe rn property

boundary of the Alamos Gold Inc. and Red Pine Explorations Inc. (“Red Pine”) strategic alliance on the

Surluga property.

Mr. Garry Clark, P.Geo., of Clark Exploration Consulting of Thunder Bay, Ontario was contracted by RT

Minerals to review historic data for the Property, identify its merits, propose an appropriate exploration

program and budget for gold exploration on the Property, as well as complete a NI 43-101 report.

The Property is comprised of 12 single cell claims and 21 boundary cell claims, covering an area of 460

hectares and is subject to a 2% net smelter returns royalty retained by the original property vendors.

Gold discoveries were made within the Property boundaries starting around 1904. Subsequent work in

the early 1900’s included shaft sinking and limited underground development at Norwalk Gold Mine and

Fred C Shaft, tunnelling at Gananoque Vein and driving a dits at the Barton Occurrence. Limited gold

production occurred from the Norwalk Gold Mine in 1904 and 1910 totalling 60 ounces of gold from 820

tons milled. A few small scale exploration programs including diamond drilling, geophysics, bedrock

sampling, till sampling and geological mapping were completed in the period from 1962 to 1997.

The Property is located in the southern part of the Wawa Greenstone Belt. Gold, silver, zinc, copper and

iron mineralization are the common associated metallic occurrence s found in the belt. On the Property

the predominant rocks are Keewatin Volcanics and Algoman Intrusives.

Fracturing and faulting play a most important role in the area. The known gold bearing veins are spatially

and structurally related to these features. The two main directions of weakness strike N20-45W and N45-

70E. The gold bearing quartz veins trend nearly parallel to the major lines of weakness and are located in

close proximity to these structures.

The historical reports document several old shafts , adits and trenches within the Property boundary

including the four main gold bearing mineralized zones. At the former Norwalk Gold Mine, gold occurs

within pyrite and arsenopyrite mineralized quartz, that lies in sheared granodiorite, and mineralized schist

composed of sericite, pyrite and arsenopyrite. At the Fred C Shaft gold is associated with numerous

massive pyrite-pyrrhotite fracture fillings within intermediate metavolcanics. Gold also occurs in-feldspar

porphyry. At the Gananoque Vein gold occurs in quartz veins with approximately 2% disseminated pyrite,

within strongly carbonatized intermediate volcanic rocks. At the Barton Occurrence gold occurs in quartz

veins mineralized with pyrite, chalcopyrite and pyrrhotite, along two parallel bands of iron formation

approximately six feet (~2 metres) wide and four feet (~1.3 metres) wide with green schist in between. A

dike of biotite picrite (kimberlite?) was also observed at the site.

The magnetics and induced polarization carried out by past and current operators have reinforced the

geological mineralized trends. Numerous historic showings are coincident to the geophysics and the

sampling and stripping verified gold mineralization and led to the discovery of the gold bearing 2 metre

to 5 metre wide quartz complex of the Red Carbonate Zone (“RCZ”) in 2017. The sampling completed to

date shows that there is low and high grade gold mineralization with a gold nugget effect in the over

mineralized system. Gold mineralization is hosted by narrow high grade sections with visible gold as well

as low grade mineralization in quartz and in the schist of the footwall and hanging wall of the overall gold

bearing section.

The extensive gold showings throughout the Property and the 2018 discovery of the RCZ indicates the

potential of economic gold mineralization and warrants further exploration. The known gold nugget

effect in the gold bearing host rocks will need to be properly assessed and sampled. In addition, the

structurally controlled gold mineralization and genesis needs further examination.

A $610,000 exploration budget is recommended for the Norwalk Property. The integrated program will

be comprised of data compilation, modelling, trenching, channel sampling, detailed mapping, assaying

and diamond drilling.

The large database needs to be compiled further and the final drill collar locations for diamond drilling on

the Red Carbonate Zone should be now initiated by the RT Minerals Corp . Qualified Person. To enhance

the extensive data base further stripping and channel sampling should provide additional data on the gold

distribution and association. Detailed mapping of newly stripped areas and previously stripped areas is

also recommended.

An initial 1,000 metre (phase I) and up to 2 ,000 metre (phase II) diamond drill programs (10 to 20 holes)

may be carried out now to fill in gaps of the Red Carbonate Zone’s prospective 600 metre strike length

between the 2017-18 drilling and the historical Gananoque gold showing. The drill core samples from this

initial 2020 drilling will provide samples to assist in defining geology, gold mineralization and define the

extent of the gold mineralization within this 600 metre long target area of the Red Carbonate Zone. This

drilling is follow up to the discovery from RT Minerals Corp. drilling from 2017-18 which intersected the

RCZ zone. The results of this drilling were previously announced by the Company on March 2, 2018.

Finally, in the event that the drilling recommended on the RCZ does not yield positive or eco nomic gold

results then the Company should then focus on the remaining +60 potential geophysical drill targets on

the eastern half of the Norwalk property identified in 2017. Most of these targets and anomalies can be

tested by drilling holes of 100 metres in core length or less.

Gold mineralization on Red Pine’s adjacent Surluga property is not an indication of same being present on

the Norwalk property. The gold zones known to exist on RT Minerals Corp. Norwalk property are separate

and distinct from those situated on the Surluga property to the north.

Mr. Garry Clark, P.Geo., is an Independent Qualified Person under National Instrument 43-101 and he has

prepared and completed the NI 43 -101 report for the Norwalk gold property at the request of the

Company. Mr. Garry Clark, P.Geo., has reviewed and approves the technical content of this press release.
