BRIGADIER IDENTIFIES THREE DISTINCT PEGMATITE SWARMS DURING PHASE-1 EXPLORATION AT NEMASKA2 LITHIUM PROJECT, JAMES BAY, QUEBEC

Field crews have completed a first phase of surface reconnaissance mapping, prospecting and sampling on Brigadier Gold Ltd.'s Nemaska2 property in James Bay, Quebec. The program successfully confirmed pegmatite occurrences mapped in historical government exploration and discovered new zones of previously undocumented shallow pegmatite mineralization. Approximately 2/3's of the Company's Nemaska2 property remains unexplored and will be the subject of near-term follow-on mapping and sampling.

Highlights:

The three pegmatite swarms mapped and sampled during Phase-1 exploration at Nemaska2 include:

• The NNW swarm is ~1,000 hectares (10,000,000 square metres) at 4kms wide (E-W) and 3kms long (N-S);
• The central swarm is ~90 hectares (900,000 square metres) at 1km x 1km.
• The SW swarm is ~100 hectares (1,000,000 square metres) at 1.2km wide and 2kms long (N-S).

The 2023 Phase-1 exploration program is designed to identify targets for a Q3/Q4 2023 drill program. Sampling results will be made public when available. Brigadier's goal for this and future exploration at Nemaska2 is to prove the existence of bulk tonnage, near-surface, lithium-bearing mineralization.

The Phase-1 program at Nemaska2 is being carried out by the Company's technical partner Geologica Groupe-Conseil ("Geologica") of Val D'or Quebec.

Phase-1 Summer 2023 Exploration Program

A total of 163 kms of tracked traverses were completed between July 10th and 28th. One hundred and twenty-four (124) pegmatite samples were collected in areas hosting pegmatite swarms in the north, northwest, central and southwest parts of the property (Figure 1). In addition, over 343 geo-observations, photos and descriptions were taken during this field program. The pegmatite dykes are generally hosted within dark pink medium grain size massive granites, vary in size from 30 cm to 4 metres, and have been observed over several tens of metres.

The samples were sent to ALS Global Laboratories of Val-d'Or and assay results will be revealed as soon as available.

Management Commentary

"We are encouraged to have successfully completed our first phase of work, which focused on systematic sampling of historically mapped pegmatite mineralization and identification of previously undocumented pegmatite occurrences", stated Robert Birmingham, President of Brigadier. "The known and newly identified pegmatite swarms comprise only a fraction of the overall property area, leaving the majority of Nemaska2 to be explored in future work programs."

The James Bay region has seen a heightened level of activity favorable to further development of a lithium supply chain within Quebec. In May, Ford Motor Company signed an 11-year lithium hydroxide purchase agreement with Nemaska Lithium. More recently Rio Tinto has moved into the district, signing option agreements with two company's, allowing for an investment of up to $175 million in exploration of early-stage lithium targets.

Nemaska2 may be one of the most conveniently located properties in the region for access, logistics and infrastructure, which will allow Brigadier to conduct its exploration programs and publish results in an efficient and timely manner.

Historical Exploration

The Quebec government has previously carried out a large sampling program and also an airborne magnetometric survey over Nemaska2 which shows the presence of several low magnetic anomalies likely corresponding with fractures or shear zones within the granitic Valiquette Pluton. These structures are generally favourable to the formation of pegmatites and other metals. The presence of pegmatites recognized during the regional reconnaissance mapping, anomalous values of Li and Cs in regional till sampling, and the presence of a major lithium deposit (Whabouchi Deposit) in the area, are all elements favourable to the existence of mineralization sought by the Company.

About Nemaska2 Lithium Project

The Nemaska2 project consists of 162 map-designated mining titles (Nemaska2 and Nemaska2 extension) covering a total area of 8,300 hectares and is located in Northern Quebec, approximately 160 kilometres east of James Bay, near the community of Nemaska. Neighbouring Brigadier's Nemaska2 project are claims held by Li-Ft Power, Brunswick Exploration, Dios Exploration, Critical Elements Lithium and about 23 kilometres to the east lies Nemaska Lithium's Whabouchi project.

Nemaska2 hosts easily accessible on-site infrastructure, including a powerline, aerodrome, railway and an accommodations camp. The property is bisected by the region's primary east-west road and is approximately five kilometres by road from additional accommodations, fuel and supplies. A large portion of the property is also accessible by all-season logging roads, eliminating the need for any use of helicopters in reconnaissance, mapping, sampling or drilling.
