Cullinan Metals Identifies Graphite Mineralization in the Extension of

LDI Graphite Mine in Québec

Vancouver, B.C., December 11, 2023 – Cullinan Metals Corp. (CSE: CMT)(OTCQB: CMTNF) (FWB: 7KO)

("Cullinan" or the “ Company”) is pleased to announce that it has successfully completed a ground

exploration program at its Lac-des-Îles West Graphite Property (the “Property”) in Quebec, Canada. Focus

of the program was a follow up ground checking of the two of the most promising airborne geophysical

targets, T1 and T2, identified immediately to the north of the Lac des Îles graphite mine (“LDI”), which is

currently owned by Northern Graphite Corp. (TSX-V: NGC) (see Figure 1 below).

Highlights

• The program successfully iden�fied graphite mineraliza�on with geological similari�es to LDI,

showcasing graphite content typically ranging from 1 -15% Cg, with occasional thin veins of

massive graphite.

• Trenching and overburden stripping work was also conducted on both conductors T1 and T2 which

uncovered graphite mineraliza�on, a part of which was extended to the edge of the Property on

the adjacent LDI mine.

• During the present field inves�ga�ons, a total of 60 rock samples were collected from the Property

and have been sent to an independent accredited laboratory, “ACTLABS” in Ancaster Ontario, for

assaying.

• Access nego�a�ons with surface landowners were successfully completed providing the necessary

access for explora�on work on the iden�fied targets.

• The program laid the groundwork for planning drill holes in the next phase of explora�on, aimed

at verifying the con�nuity of large flake surface graphite mineraliza�on at depth and along strike.

Target areas T1 and T2 boast dimensions of 500 m in the e ast-west direc�on and over 1,000 m

long in the north-south direc�on.

Mr. Marc Morin, CEO of Cullinan Metals Corp., expressed his enthusiasm for the recent developments,

s t a � n g , " T h e p o s i � v e o u t c o m e s f r o m o u r L a c-des-Îles West explora�on program mark a significant

milestone for Cullinan Metals. Iden�fying graphite mineraliza�on with similari�es to the exis�ng LDI mine

underscores the poten�al of our property and posi�ons us strategically in the growing graphite market.

We are par�cularly encouraged by the successful nego�a�ons with landowners, allowing us to proce ed

with our explora�on plans. The forthcoming assay results from the rock samples and the planned drill

holes in the next phase will be crucial in advancing our understanding of the Property's graphite poten�al.

This is an exci�ng �me for Cullinan, and we look forward to building on these achievements as we con�nue

to unlock the value of our assets."

About the Lac-des-Îles West Graphite Property

The property is in Bouthillier township in Saint -Aimé-du-Lac-des-Îles area adjacent to the western and

northern limit of the LDI Graphite Mine approximately 17 kilometers southwest of the town of Mont-

Laurier on NTS map sheet 31J05. The property is locally accessible through a series of forestry service

roads and the main V illage Road 0 (Chemin du Village 0) that cuts through the property, connecting the

property to Highway #309 which is about two kilometers east of the property. Geologically, the Lac -des-

Îles West Graphite property is within a geological setting very similar to the LDI Graphite Mine. The LDI

Graphite Mine is associated with paragneisses, biotite gneisses and marbles. The area is mainly underlain

by Precambrian metasedimentary rocks of the G renville Series comprised of quartzofeldspathic,

garnetiferous paragneiss, and marble beds.
