MONTREAL, Oct. 08, 2024 (GLOBE NEWSWIRE) -- Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; FRANKFURT:1XQ; “BRW” or the “Company”) is pleased to report the first set of results from the Mirage summer drilling campaign. The Mirage Project is located in the Eeyou Istchee-James Bay region of Quebec, approximately 40 kilometres south of the Trans-Taiga Road. This drilling program concluded with a total of 23 drill holes for 4,871 meters. Since the beginning of 2024, BRW has drilled approximately 12,000 meters to discover, delineate and expand the spodumene bearing pegmatites dykes at Mirage.
This campaign focused on the Central Zone, including the MR-6 and MR-3 dykes (see June 4, 2024 press release), and has continued to intersect wide and well mineralized intervals on their extension and at depth.
Highlights include:
Several new lithium pegmatites were intercepted immediately surrounding MR-6 dyke located in the Central Zone. Significant dyke staking is observed to the East and North of MR-6 The mineralization in the Central Zone is now identified over across multiple holes stretching over 1,000 meters of strike length.
Multiple significant, near-surface intervals extending the MR-6 dyke with 1.75% Li2O over 40.4 meters in drill hole MR-24-73, 1.07% Li2O over 24 meters in drill hole MR-24-74 and 1.25% Li2O over 16 meters in drill hole MR-24-72.
Three new stacked dykes confirmed located 250 meters to the East of MR-6 with 1.25% Li2O over 26 meters, 1.49% Li2O over 26.2 meters and 1.93% Li2O over 22.35 meters all in drill hole MR-24-76.
Brunswick Exploration will start metallurgical studies in the coming weeks for the MR-6, MR-4 and MR-3 dykes.
Mr. Killian Charles, President and CEO of BRW, commented: “Once again, our drilling underscores the significant potential of the Mirage project. We continue to rapidly identify and expand multiple pegmatite dykes in the core of the project in the Central Zone. These dykes still remain open in multiple directions with continued evidence of near-surface dyke staking. As we continue to delineate these targets, we have begun preparation for metallurgical studies which we believe will highlight the typically coarse mineralization observed at Mirage.”
“With more exciting results forthcoming at Mirage and several important exploration updates on our grassroot portfolio to be released in the coming weeks, I invite BRW shareholders to follow closely our expected press releases this fall.”

Mirage Project Drilling Overview
The Mirage Project comprises 427 claims located roughly 40 kilometers south of the Trans-Taiga Highway in Quebec’s James Bay region and 34 kilometers northeast of Winsome Resources’ Adina Project.
The summer drilling campaign focused on extending the mineralized dykes recognized during the last two drilling campaigns. The holes MR-24-72, Mr-24-73 and MR-24-74 (see Figure 3) extended the MR-6 dyke over 100 meters to the West and to the South. MR-6 has been now drill traced over an area measuring 250 meters by 250 meters as seen on Figure 2 with an average thickness of 60 meters. Mainly identified at surface from 0 to 100 meters starting from drill hole MR-24-28, it plunges to the West up to 200 meters vertical. MR-6 remains open to the West and to the North.
Evidence of significant stacking was discovered 35 meters under MR-6 where drill hole MR-24-73 intercepted 17.75 meters at 1.42% Li2O and hole MR-24-73 cut 7 meters at 1.40% Li2O.

The hole MR-24-76 (see Figure 4) expanded the three major mineralized dykes identified in hole MR-24-60 (see April 25, 2024 press release). This new hole continues to intersect similar wide high-grade mineralization observed to date. At this time, it is believed they are not related to MR-6 even if they occur in close proximity to the dyke as they appear to stand as a new stacked dyke geometry. The dykes remain open to the North, South and East.

Finally, hole MR-24-77, located about one kilometer WSW of MR-6, discovered a previously unknown lithium-tantalum pegmatite dyke measuring approximately two meters near the start of the hole. This new intersection significantly extends the lithium bearing pegmatite field of the Central Zone, west of MR-3. However, the hole was unable to explain the targeted gravity anomaly. Analysis of the hole revealed a major lithium anomaly in the country rock throughout its entire length indicative of a potential neighboring lithium dyke. Further drilling will be required to expand the full potential of this new area.
QAQC
All drill core samples were collected under the supervision of BRW employees and contractors. The drill core was transported by helicopter and by truck from the drill platform to the core logging facility in Val-d’Or. Each core was then logged, photographed, tagged, and split by diamond saw before being sampled. All pegmatite intervals were sampled at approximately 1-meter intervals to ensure representativity. Samples were bagged; duplicated on reject, blanks and certified reference materials for lithium were inserted every 20 samples. Samples were bagged and groups of samples were placed in larger bags, sealed with numbered tags, in order to maintain a chain of custody. The sample bags were transported from the BRW contractor facility to the ALS laboratory in Val-d’Or. All sample preparation and analytical work was performed by ALS by ICP-AES according to the ALS method ME-MS89L. All results passed the QA/QC screening at the lab and all inserted standard and blanks returned results that were within acceptable limits. All reported drill intersections are calculated based on a lower cutoff grade of 0.3% Li2O, with maximum internal dilution of 5 meters. Host basalts adjacent to the dykes may grade up to 0.3% Li2O but were excluded from the reported intersections.
