Vancouver, B.C. – February 14, 2023 – RT Minerals Corp. (TSXV: RTM) (OTC Pink: RTMFF) (the “Company” or “RTM”) announces that it has acquired by map staking (MLAS) 91 claims consisting of approximately1,927 hectares (4,762 acres) covering the Case Batholith (the “Case Batholith Properties”) centered on Heighington Township, 85 km northeast of Cochrane, Ontario.
The Case Batholith Properties are 100% owned and royalty free. The properties occur within the
boundaries of the Case Batholith and are specifically located in Heighington, Kenning, Sequin, and Case
Townships (Figure 1). Five properties are situated 12 km north of the Power Metals Corp. (“Power
Metals”) Case Lake lithium/cesium discovery in Steel Township, Ontario (Figure 2).

The Power Metals discovery contains significant lithium and cesium mineralization within pegmatitic
lithologies throughout northeast trending dyke and isolated laccolith (dome) complexes. It is these
lithologies of the Case Batholith that RT Minerals now owns and will be subject to future exploration by
the Company.
The entire Case Batholith complex is an oval-shaped complex that is approximately 150 km long and 60
km wide. The Case Pegmatite systems, associated with the batholith and its margins, appear to reside
within the five largest known lithium-cesium bearing complexes in the geologic region of the Superior
Province of Ontario.
The entire Case Batholith complex is virtually unexplored (Figure 3). Excluding the Case Lake discovery of Power Metals, at the extreme southeastern edge of the Case Batholith, only one significant borehole has penetrated the Case Batholith during 2007 exploration for gold. This hole was drilled by Lake Shore Gold Corp., drill hole LA-07-01, located immediately northeast of the Company’s Ireland property in Ireland Township. This hole contained anomalously high cesium (“Cs”) values within igneous assemblages (samples 135279 to 135281, Cs – 76ppm over 1m, 42ppm over 0.70m, and 56 ppm over 0.50m, all within 90m of surface – MNDM files 20000003914 /20005893).

Douglas Andrews, the Company’s President and CEO, states: “We are pleased to add lithium and cesium
prospects to our portfolio of properties. With the assistance of government initiatives such as the Ontario Government’s Critical Minerals Directive and the federal government’s new Critical Mineral Exploration Tax Credit, we have positioned the Company to capitalize on what is now a major exploration and staking rush for rare earth elements in northern Ontario and Quebec, within geologic parameters of the Superior Province. This includes the major and leading Canadian world-class rare earth element discovery by Patriot Battery Metals Inc. in the eastern James Bay region of Quebec. Detailed investigations from existing magnetic signatures, covering the entire Case Batholith, has resulted in the identification of several magnetic responses similar to that which characterize the Power Metals Case Lake, Ontario, discovery. All of the RT Minerals claim blocks have been acquired on the basis of magnetic signatures resembling northeast trending dykes and laccolith structures. The total residual magnetic field response exhibits several magnetic features located near the Power Metals Case Lake discovery (Figures 4 and 5)(MNDM files Map 82815). It is postulated that many of the magnetic responses represent pegmatitic dykes and laccolith (dome) complexes that are contained within the tonalite/granodiorite rock assemblages of the Case Batholith. Several RT Minerals claim blocks cover prominent magnetic features that lie along the outer margins of the Case Batholith, as does the Power Metals discovery”.

About RT Minerals Corp.
RT Minerals Corp. is a junior exploration company listed on the TSX Venture Exchange under the symbol
“RTM”. The Company holds a 100% royalty-free interest in a portfolio of rare earth element, gold and
base metal properties in Ontario: the Ireland, Milligan, Blakelock, McQuibban and Timmins properties.
The Company also holds an option to acquire a 100% interest in the Link-Catharine RLDZ gold property
located 22 km south-southeast of the town of Kirkland Lake, Ontario.
Ireland Property (Rare Earth Element) is a royalty free 52 claim block (421 Ha) covering an inferred
carbonatite complex (the “Ireland Complex”) located in Ireland Township, 45 km northeast of Smooth
Rock Falls, Ontario. The Ireland Complex is 100% owned by RTM and is approximately 4.0 km long, 2.8 km wide, oval shaped and is positioned along a southern extensional splay fault contained within the
Kapuskasing Structural Trend. The Kapuskasing Structural Trend contains several well documented
carbonatite complexes that contain Niobium, Iron, Titanium and Rare Earth Element resources within
various assemblages of carbonatite rocks.
Case Batholith Group (Rare Earth Element) consists of 91 claims of approximately 1,927 hectares (4,762 acres) covering the Case Batholith (the “Case Batholith Properties”) centered on Heighington Township, 85 km northeast of Cochrane, Ontario. The Case Batholith Properties are 100% owned and royalty free. The properties occur within the boundaries of the Case Batholith and are specifically located in Heighington, Kenning, Sequin, and Case Townships. Five properties are situated 12 km north of the Power Metals Case Lake lithium/cesium discovery in Steel Township.
Link-Catharine RLDZ Property (Gold) is comprised of fifteen unpatented single cell mining claims with a
total area of 220 hectares in one claim block. The Link-Catharine property is located 22 km southsoutheast of the town of Kirkland Lake, Ontario. RTM has an option to earn a 100% interest in this property subject to a 2% NSR.
Milligan Property (Gold) is a royalty free 16-claim block (129 Ha) located approximately 75 km northeast
of Timmins, Ontario, and is 100% owned by RTM. The Milligan property covers the southeast extension
of the volcanic stratigraphy hosting the Eastford Lake gold discovery of 142.2 g/t Au over 3.0 m announced by Explor Resources in 2009.
.
Blakelock Property (Gold) is a royalty free 9-claim block (73 Ha) located approximately 75 km northeast
of Cochrane, Ontario, and is 100% owned by RTM. The property is host to a massive east-west trending
magnetic high intrusive complex that was subject to limited drilling in 1967.
Mcquibban Property (Gold) is a royalty free 19-claim block (153 Ha) located approximately 50 km north
of Cochrane, Ontario, and is 100% owned by RTM. The property hosts a strong 3.0 km long east-west
trending inferred oxide facies banded iron formation, in which one historical drill hole encountered a gold
mineralized interval of 5.47 g/t Au over 1.2m.
Timmins Property (Base Metals) is a royalty free 16-claim block (129 Ha) located approximately 50 km
southeast of Timmins, Ontario, and is 100% owned by RTM. The property features several mineralized
fault systems that suggest proximity to a base metal source.
