Brunswick Exploration Inc. announced inaugural drilling results from the Mirage Lithium Project, located in the Eeyou Istchee-James Bay region of Quebec. The initial 5,000 meters drilling campaign outlined four major spodumene-bearing pegmatite dykes where significant intervals of continuous lithium mineralization were drilled. All pegmatite dykes drilled to date start at surface, are open in all directions, and are located within an area of approximately two by two kilometers.

Several other outcropping dykes and promising targets have yet to be drilled, including the sizeable boulder train to the southwest of the dyke swarm. The aim of the 2023 drilling campaign was to test at shallow depths (less than 150 meters vertical depth) the pegmatite dykes mapped from surface to determine their geometry and orientation. Thirty-six (36) diamond drill holes were completed for a total of 5,090 meters drilled to date.

Thirty-three (33) of the 36 holes drilled during the 2023 campaign intercepted mineralized pegmatites. The mineralized pegmatite dykes discovered at the Mirage Project are distributed along three major trends in a NE-SW axis, the North, Central and South Zones, within a two by two kilometers area. The mineralized dykes are massive, very coarse-grained, with a mineralogy consisting of quartz, white feldspar, minor muscovite and black tourmaline, light grey spodumene and traces of beryl.

The consistently decimetric spodumene mineralization often reaches up to 50% of the modal mineral content. This inaugural drilling campaign has successfully extended the mineralized pegmatites over a combined distance of 1.5 km and demonstrates excellent continuity with several high-grade zones intersected to date. All pegmatite dykes remain open in all directions.

In addition, several other outcropping spodumene-bearing pegmatites remain to be drill-tested. Central Zone: The MR-3 pegmatite dyke intercepted in the Central Zone show significant apparent thicknesses of up to 50.6 meters at 1.06% Li2O (MR-23-07) with a moderate dip at around 50 degrees towards the south with true thickness estimated at 95% in all reported holes. The main dyke in the Central Zone is oriented NE and reaches the surface where it can be traced continuously for more than 400 meters with continuous thickness in excess of 40 meters and grade averaging approximately 1.00%.

To date, the main dyke in the Central Zone is defined by six drill holes (MR-23-05 to 07 and MR-23-09 to 12) and remains open in all directions. A second, unmapped dyke (MR-3A) was identified in drill hole MR-23-08, marking the first blind discovery of a pegmatite dyke at Mirage. The hole only partially intercepted the margin of the dyke and is not representative of the grade or width of the MR-3A Dyke.

Drill hole MR-23-35 targeted this new dyke and assays are still pending. North Zone: Four shallow drill holes were carried out in the North Zone (MR-23-01 to MR-23-04). All holes intercepted two spodumene bearing pegmatite dykes, MR-1 and MR-2. Two holes MR-23-01 and MR-23-02 returned bonanza grade interval: 24.5 m at 2.18% Li2O and 25.8 m at 2.57% Li2O respectfully.

The MR-1 dyke likely dips to the north, and the true thickness is estimated to be 90% of the core lengt. Both dykes remain open in all directions. Furthermore, another three spodumene-pegmatite outcrops located up to 1 km further east remain undrilled in the North Zone.

South Zone: Preliminary results from the South Zone, all from pegmatite dyke MR-4, also show significant near-surface bonanza grade mineralization. The dyke has been continuously traced by drilling over more than 750 meters with a moderate dip of 45 degrees to the south. Only one drill hole from the dyke in the South Zone is reported in this news release; MR-23-14 returned 16.2 m at 2.75% Li2O.

Similar bonanza mineralization has been observed along the entire length of the dyke and remains open in all directions.
