NEWS RELEASE

RT MINERALS CORP DISCOVERS NEW MINERALIZED OUTCROP CONFIRMING SIGNIFICANT EXTENSION OF THE

ULTRAMAFIC LAYERED INTRUSIVE ON THE NORDICA PROPERTY, ONTARIO.

Vancouver, B.C. – August 3, 2023 – RT Minerals Corp. (TSXV: RTM) (OTC Pink: RTMFF) (the “Company” or “RTM”)

announces results from a reconnaissance and field rock sampling program at the Nordica property carried out in

the late spring to present 2023. The Nordica Property is 100% owned by RTM and located 60 kms southeast of

Timmins, Ontario.

Current sampling results are focused on RTM verification of mineralized outcrop within the vicinity of the original

and historic discovery outcrop at the southeast end of the Nordica intrusive (MNDM files OFR 6102), confirmed by

current RTM samples 63457 – 63460. In addition, a newly discovered outcrop at Sylvia Creek approximately 2.7

kms to the northwest is represented by RTM samples 63455 and 63456 (Figure 1). A total of six chip samples from

outcrop consisting of ~3 kg per sample were taken and all samples carried variable mineral content.

Current surface sampling confirms mineralization near the original historic discovery outcrop and includes current

chip sample 63457 containing 2459 ppm Nickel (Ni), 1470 ppm Copper (Cu), 233ppm Cobalt (Co), 0.25% Chromium

(Cr); and chip sample 63458 containing 1155 ppm Ni, 664 ppm Cu, 116 ppm Co, 0.94% Cr; and chip sample 63459

containing 877 ppm Ni, 371 ppm Cu, 93.4 ppm Co, 1.51% Cr; and chip sample 63460 containing 589 ppm Ni, 852

ppm Cu, 46.8 ppm Co, 0.05% Cr.

In addition, from this same area of the historic discovery outcrop current RTM chip sample 63457 returned 0.19 g/t

Palladium (Pd) and sample 63460 returned 0.26 g/t Pd.

Of significant interest are the current samples 63455 and 63456 taken by RTM from outcrop. These two chip

samples are located at Sylvia Creek approximately 2.7 kms northwest of the historical discovery outcrop (Figure 1).

In addition, massive to semi-massive layered chromite outcrop was discovered at Sylvia Creek where these

samples were taken. Sample 63455 returned 540 ppm Ni, 3.95% Cr, 0.17% titanium (Ti), 320 ppm Vanadium (V).

Sample 63456 returned 701 ppm Ni, 11.9% Cr , 0.30% Titanium (Ti) and 878 ppm V.

The discovery of this layered chromite bearing unit 2.7 kms to the northwest is the first significant verification of

ultramafic layered intrusive bedrock outside the immediate 400m by 400m area of the original discovery outcrop

(Figure1).

The outcrop is aligned with magnetics that strongly suggest that the entire Nordica Intrusion could extend for at

least 2.7 kms along strike to the northwest. In addition, the outcrop is evidence that the intrusion is located further

westward within an area previously mapped as metavolcanics, this significantly increases the potential overall size

of the Nordica Intrusive complex (Figure 2). A further six 4 kg samples from outcrop in this area are pending.

The current inferred size of the Nordica intrusion, excluding magnetic signatures, is approximately 250m wide

(drill holes 98-01, 98-02 and outcrop) , approximately 2.7 kms long (drill hole 98-01 to the newly discovered

outcrop), and approximately at least 240 m deep (historic drill holes 98-01 and 98-02).

The company has developed a plan for follow up exploration within this new high priority target area including

additional surface exploration to locate additional ultramafic assemblages followed by diamond drilling. Drilling in

a northeasterly direction along the 2.7 km length target area will attempt to intercept additional ultramafic

assemblages within the layered Nordica intrusive (pyroxenite, peridotite and Gabbro) and to test for further Ni, Cu,

Pt, Pd and Co mineralization within the intrusive. At least five widely spaced 300m drill holes would be required to

initially test this target over the 2.7 km length. This work program is subject to the Company securing exploration

financing.

Quality Controls, Sampling and Assaying

All six 3 kg chip samples from outcrop, in the current RTM field program, were assayed using Total Digestion ICP-

OES and Fusion XRF. Assaying was managed and carried out by Activation Laboratories Ltd., Timmins, Ontario and

Swaslabs Ltd., Kirkland Lake, Ontario, both are ISO/IEC 17025 accredited assay labs. The current assay results

detailed herein are from RTM’s initial field sampling. The assays contained herein may not be indicative of all rock

types. Additional sampling is required to determine the significance and extent of these results. A further six 4 kg

samples from the Sylvia Creek area of the newly discovered outcrops are pending.
