BRUNSWICK EXPLORATION OUTLINES NEW SPODUMENE RICH BOULDER TRAINS AT MIRAGE AND LAUNCHES SUMMER DRILL CAMPAIGN

Brunswick Exploration Inc. has completed the 2024 prospecting program and started a 5,000-metre summer drill program at the Mirage project, located in the Eeyou Istchee James Bay region of Quebec. To date, 71 drill holes and more than 12,000 metres have been drilled on the Mirage project, which have delineated nine near-surface spodumene-bearing pegmatite dikes, all of which remain open at depth and along strike. Approximately two dozen additional dikes, with widths ranging from eight metres to approximately 20 metres, have also been intercepted in the two previous campaigns with minimal to no follow-up work. The proposed program will focus on MR-6, MR-3 and MR-4 as well as new targets that were delineated using drilling, geophysics, till mineralogy and prospecting.

Killian Charles, president and chief executive officer of Brunswick Exploration, commented: "With a shortened 2023 exploration campaign due to forest fires, we were eager to complete our ground exploration work at Mirage. The program was highly successful and outlined four new high-priority areas of interest within the trend of mineralization at Mirage. These targets are hosted along favourable structural environments and will be drill tested during the forthcoming drilling campaign. Alongside the major pegmatitic dikes already outlined, Mirage remains a target-rich project with multiple avenues of exploration growth."

Overview of prospecting program at Mirage

Prospecting and detailed mapping were carried out by the Brunswick exploration team in June. This effort was supplemented by a till survey performed in the spodumene-bearing boulder train and in its vicinity to better delineate potential sources and drilling targets. Some samples returned coarse spodumene crystals in till. Interestingly, some samples outside of the main boulder trend also returned significant spodumene grain count, indicating the potential for new sources. The till survey will be expanded to the entire project in the fall to continue expanding the trend of mineralization at Mirage.

The prospecting campaign also outlined numerous new spodumene-bearing boulders. Significantly, these boulders were found to the west and southwest of the main spodumene boulder train previously identified in 2023. The size (up to 200 cubic metres) and angularity of the boulders indicate their sources lie close by, likely outside of the known mineralization in the Central and South zones. Combined with the till surveys and geophysics completed to date, Brunswick Exploration strongly believes significant mineralization remains to be found at Mirage.

Quality assurance/quality control

Tills were collected by Brunswick Exploration staff. The 10-kilogram samples were sieved directly on site to two different size fractions: eight millimetres and two millimetres. Pegmatite clasts were counted in the eight-millimetre fraction and the presence of spodumene mineralization was confirmed through UV (ultraviolet) light.
