RT MINERALS CONFIRMS EXTENSION OF SURFACE NICKEL, COBALT, CHROMITE, Pt AND Pd

MINERALIZATION IN THE ULTRAMAFIC LAYERED INTRUSION ON THE NORDICA PROPERTY,

ONTARIO, AND TERMINATES OPTION ON LINK CATHERINE RLDZ GOLD PROPERTY, ONTARIO.

Vancouver, B.C. – September 29, 2023 – RT Minerals Corp. (TSXV: RTM) (OTC Pink: RTMFF) (the

“Company” or “RTM”) is pleased to announce results from the second group of surface samples from the

Nordica property carried out in the summer of 2023. The Nordica property is located approximately 40kms

west of Kirkland Lake and about 60kms southeast of Timmins, Ontario.

Current assay results are from two samples from a second location of mineralized outcrop located about

5m from the first reported Cr, Ni, Co , Cu, Pt and Pd discovery outcrop announced August 3, 2023. These

first and second sample locations are situated approximately 2.7 kms to the northwest of the historic

discovery of similar mineralization on the property.

The two most recent samples from this second outcrop discovery are samples 63463 and 63466.

Massive to semi-massive layered mineralized outcrop was sampled and assayed. Sample 63463

(massive chromite) returned 566 ppm Ni, 12.03% Cr, 618 ppm Vanadium(V) and 0.15g/t Pd. Sample

63466 (semi-massive chromite) returned 679 ppm Ni, 6.47% Cr, 350 ppm V and 108 ppm Co.

This second outcrop of mineralized ultramafic intrusive is additional evidence that ultramafic layered

intrusive bedrock exists outside the immediate 400m by 400m area of the historic di scovery outcrop,

trenching and diamond drill holes ( Figure1) situated 2.7 kms to the southeast. This currently sampled

section of exposed Cr, Ni, Co, Cu, V, Pt and Pd mineralized outcrop is at least 5.0m thick and appears to

widen to the north.

The outcrops are aligned with magnetics that strongly suggest that the entire Nordica Intrusion could

extend to a total of 5 kms of strike length. In addition, the outcrops are evidence that the intrusion is

located further westward within an area previously mapped as metavolcanics and as such significantly

increases the inferred potential size of the Nordica Intrusive complex (Figure 2).

The current inferred size of the Nordica intrusion (excluding magnetic signatures) is approximately 250 m

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

Creek outcrop), and approximately 240 m deep (drill hole 98-01 and 98-02).

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

including additional surface exploration to locate additional ultramafic assemblages followed by diamond

drilling. Diamond drilling will be collared to intercept the additional ultramafic assemblages within the

layered Nordica intrusive ( pyroxenite, peridotite and Gabbro) that carry Ni, Cu, Pt, Pd, Cr and Co

mineralization. Drill permits are in place and further exploration on Nordica is subject to financing.

Quality Controls, Sampling and Assaying

Both of the 3 kg chip samples from outcrop detailed herein 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 program. 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.

Option Terminated, Link Catherine RLDZ Gold Property, Ontario

RTM has abandoned its option to earn 100% of the Link-Catherine RLDZ Gold Property (“LCGP”) located

approximately 22 km south southeast of Kirkland Lake, Ontario.

The Company had early exploration success on the LCGP throughout 2020 and early 2021, but was

unable to demonstrate grade and continuity of mineralization in follow up drilling of the specific zones

targeted by the Company in the 2021-22 field season and property assessment review.

In addition, with the weakening of the senior and junior gold sector, the required continued contractual

RTM work and property payments for LCGP, no longer meets RTM’s risk to reward ratio, or RTM’s view

of the reasonable current fair market value for a property at this stage of exploration.

Accordingly, the Company will write off Exploration and Evaluation Assets relating to the LCGP for the

year ending November 30, 2023.

RTM continues to hold 11 rare earth, critical mineral-base metal, and gold properties-projects,

aggregating over 9,000 Ha of prospective exploration ground within a 150 km radius of Timmins, Ontario.

All of these properties-project areas are staked claims (MLAS, Ontario), with 8 of the properties royalty

free, and all of these claims are 100% owned by RTM.
