CULLINAN METALS SIGNS LOI TO ACQUIRE ONTARIO LITHIUM PROPERTIES

Vancouver, B.C. – August 21, 2023 - Cullinan Metals Corp. (CSE: CMT) (OTCQB: CMTNF) (FWB: 7KO) ("Cullinan"

or the "Company") is pleased to announce that it has signed non-binding letters of intent (the “LOI”), with two

vendors (“Vendors” or individually, “Vendor One” and “ Vendor Two”) to acquire a 100% interest in and to a

series of highly prospective lithium mineral properties (the "Properties") located in Northwestern Ontario.

The LOI with Vendor One is dated July 26, 2023, and it includes a series of mineral projects which are commonly

referred to as “Flower Falls”, “Lily Pad”, “Dory Ariel-Lake”, “West Haig”, “East Haig”, “Ratte Lake” and “Flash Lake

North”.

The LOI with Vendor Two is dated July 31, 2023, and it includes two mineral projects that are commonly referred

to as “Waspesi” and “North Maskerine”.

The Properties:

The Flower Falls, Dory - Aerial Lake, West Haig, East Haig, and Flash Lake properties are located in a lithium -

favorable geological setting in the vicinity of the Georgia Lake, Mavis Lake , Separation Rapids and GT1’s Root

Lake properties in Northwestern Ontario where lithium prospects and deposits have been discovered .

Geologically, the properties are hosted within metasediments of the English River Subprovince between two

muscovite-bearing peraluminous granites. Lithium has been the primary mineral of economic interest in this area

and the lithium mineralization style is dominantly hosted within spodumene-bearing pegmatite dykes and sills.

The pegmatites of the area seem to be of magmatic origin and are generated by the progressive crystallization

of granitic magma. They usually appear as loosely tabular dykes and sills, attenuated lenses, and small irregular-

shaped bodies. Metasediments make excellent hosts for lithium-bearing pegmatites. The deposit model for the

area indicates that rare -element lithium-cesium-tantalum (Li, Cs, Ta) pegmatites can fractionate up to 10km

away from their parent granite (Breaks et al., 2003).

Lilypad is directly adjacent to significant Ta Cs Rb mineralization. The closest significant mineralized outcrop on

Lillypad is the JJ Dyke in adjacent property to the SE. Near the southwest edge of the property, on OGS map 992

are some small outcrops that are noted to be pegmatites. No previous drill holes or geochemistry was found in

the project area. Very minimal work has been done on these projects.

The lake sediment sampling data collected by the Ontario Geological Survey indicates that the English River

Subprovince is host to lithium , yet it is vastly unexplored for LCT- pegmatites. Lake sediment lithium sample

results suggest the muscovite-bearing granite is fractionating towards the northeast.

Terms of LOIs:

Pursuant to the terms of the LOIs, the Company was granted the right to conduct a full due diligence investigation

on the P roperties. This includes the right to visit the Pr operties and to conduct preliminary sampling and

exploration work to the extent permitted by applicable mining laws.

Upon discovery of spodumene mineralization on any of the P roperties (the “Discovery”), the relevant Vendor

and the Company will execute either:

a) An assignment and assumption agreement (the “Option Agreement”) pursuant to which the Vendor will

assign to the Company all rights and interests to the property purchase options agreements; and/or

b) A property purchase agreement (the “ Purchase Agreement”) pursuant to which the Vendor will grant

all rights and interests in and to the Properties to Cullinan.

The considerations for the Option Agreement and/or Purchase Agreement will be negotiated between the

Vendor and Cullinan immediately after the Discovery.

Marc Morin, CEO, said, "We are very excited to have entered into the LOIs. The Properties are highly prospective

for lithium and also give Cullinan shareholders the opportunity of discovery across nine (9) different locations in

Northwestern Ontario .” Marc Morin continued, “There will be no payments or share issuances until the

Discovery.”
