RT MINERALS CORP. ACQUIRES ADDITIONAL LITHIUM/CESIUM MINERAL CLAIMS AND PROSPECTS IN
NORTHEASTERN ONTARIO, CANADA
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 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 (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 system s, 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 ident ification of several
magnetic responses similar to that which characterize the Power Metals Case Lake, Ontario, discovery. All
of the RT Mineral s claim blocks have been acquired on the basis of magnetic signatures resembling
northeast trending dykes and la ccolith 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, Case Batholith Group, 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 – Case Batholith) is a royalty free 52 claim block of 421 Ha (1,040
acres) 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 K apuskasing 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 south -
southeast 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
