Jourdan RESOURCES INC. publish the final set of assay results of its summer/fall 2022 drilling campaign on its Vallee Lithium Project, located 35 km north of Val-d'Or in Quebec, Canada. Results from the final thirteen holes have been received following the results of 19 holes disclosed in the Company's previous news releases dated January 28, 2023 and February 15, 2023. These final assay results confirm that the lithium-bearing pegmatite system at Vallee remains open for expansion to the east along strike, down-dip and to the south of the 2021 and 2022 drill holes.

The Company and its partner, North American Lithium Inc. (‘NAL', a majority owned subsidiary of Sayona Mining Ltd. ‘Sayona'), recently announced the intention to commence an aggressive 24,000 m drilling program to commence in May on the Vallee project with the objective of expanding and defining sufficient mineral resources to supply increased tonnages to the NAL concentrator located adjacent to the property. NAL's concentrator commenced processing operations on February 27, 2023, and the first spodumene concentrate produced from the plant was announced in March 2023. Five of the holes reported in this last set of assay results encountered lithium concentrations exceeding 0.50% Li2O.

Highlights from this batch of samples was from the bottom half of hole VAL22-8-5, which encountered 0.82% Li2O over 8 m from 125.0 to 133.0 m. Previously, the Company announced in its February 15, 2023 news release that an intersection from the top half of hole VAL-22-8-5 intersected 13.6 m of 0.50% Li2 O from 89.0 m to 102.6 m. These results confirm the presence of a new northern high-grade lithium-bearing pegmatite that has been traced by drilling over a strike length of over 300 m and remains open at depth and to the east along strike. This new lithium-bearing pegmatite intersected in VAL22-8-5 and main pegmatite swarm to the immediate south had both not been previously identified before the Company's 2021 and 2022 drill programs. The 2022 summer/fall drilling program was conducted to the east of the Company's previous drill programs and targeted the eastern and southeastern extension of the known spodumene-bearing pegmatite swarm. The Company intends to use the results of the drilling and assaying and the upcoming 2023 program to update its geological model and to help the Company establish an initial mineral resource estimate at the Vallée property.

The drill program was conducted by Forage LaMontagne Fortier from Rouyn-Noranda, Québec, under the supervision of Alex Beloborodov Géologue Inc. (ABG Exploration) of Laval, Quebec. All samples from the new drill program have been sent to Impact Global Solutions Inc.'s laboratory in Delson, Québec (‘IGS') for analysis by sodium peroxide fusion and ICP finish. This laboratory is recognized by the industry and accredited ISO/MEC 17025 by the Standards Council of Canada.

In addition to the quality assurance and quality controls (‘QA/QC') employed by IGS, Jourdan developed a rigorous QA/QC protocol for its operators, including the insertion of analytical standard samples, duplicates and coarse silica blanks on a systematic basis.
