Mirage
The Mirage Project comprises 427 claims with a total surface area of 21,230 hectares (staked and optioned claims), located roughly 40 kilometers south of the Trans-Taiga Highway in Quebec’s James Bay region. Fruitful discussions with a geologist that worked the area twenty-five years ago for gold exploration led to the staking of the BRW claims, as he recorded the presence of several angular pegmatitic glacial boulders hosting well-defined, decimetric spodumene crystals. The largest observed boulder measured 8 meters by 4 meters by 3 meters. Pale grey spodumene crystals were positively identified by BRW in the summer of 2023 following lithium flame tests and UV light.
In the fall of 2023, BRW discovered several high grade spodumene outcrops over a 2.5 kilometer trend as well as an adjacent 3.0 kilometer spodumene bolder train that has different minerology than the discovered outcrops. As such, BRW completed a successful 5090 meter, 36-hole diamond drill program that delineated what is now know as the MR-1, MR-2, MR-3 and MR-4 dykes. Drilling highlights include 2.57% Li2O over 25.8 meters, 50.6 m at 1.06% Li2O, 16.2 m at 2.75% Li2O and 3.28% Li2O over 10.6 meters (See Press Release December 4th 2023 & December 19th 2023).
A 15,000 meter drill program will be launched in Q1 2024 to further expand and delineate the open dykes while drill testing for new blind targets and additional spodumene outcrops that were not tested in the 2023 program.
Elrond
The Elrond Project comprises 136 claims with a total surface area of 7,048 hectares, located roughly 12 kilometers east of the Billy Bishop Highway in Quebec’s James Bay region. The Elrond Project is part of the Mythril Option agreement with Midland Exploration Inc. whereby BRW can earn a maximum of 85% interest in the project. For further details see press release dated November 10 2022.
In the fall of 2023, BRW uncovered a new, undocumented spodumene-bearing pegmatite, known as the Arwen showing, that is exposed over a surface area measuring approximately 250 meters by 100 meters, dipping very shallowly to the north. The pegmatite remains open in all directions (See press release dated October 3rd 2023).
The Arwen outcrop is well mineralized in spodumene throughout the showing with an apparent higher-grade zone, containing up to 30% spodumene, which has a visible extent of approximately 75 by 15 meters. The spodumene crystals are well formed and up to 30 centimeters in length with an off-white color and were confirmed through LIBS analysis and UV light.
An inaugural drill program is planned for Q1 2024 to drill test the Arwen pegmatite.
Anatacau Main
In the fall of 2022, BRW signed an option agreement with Osisko Development Corp. (TSX-V: ODEV) to acquire a 90% interest in the Anatacau Property (the “Property”) located in the James Bay-Eeyou Istchee region of Quebec.
In the summer of 2023, BRW discovered a significant lithium pegmatite outcrop, measuring at least 100m long by 15m large known as the Anais showing. The outcrop is within a larger cluster of pegmatite dykes all of which contain high grade lithium mineralization (See Press Release July 13th 2023).
This discovery is located 22km east of BRW’s Anatacau West and Allkem’s James Bay Project along a large-scale E-W deformation corridor which is host to the known lithium-bearing pegmatite dykes in the region. This structure runs through both the Anatacau West and Anatacau Main properties over a total of 15.5 km, all of which has never been explored for lithium.
Anatacau West
In the fall of 2022, BRW signed an option agreement with Osisko Development Corp. (TSX-V: ODEV) to acquire a 90% interest in the Anatacau Property (the “Property”) located in the James Bay-Eeyou Istchee region of Quebec and which is host to lithium mineralization. Furthermore, one block of the Anatacau property is located just east of Allkem’s (TSX: AKE) James Bay Lithium deposit (previously known as the Cyr deposit). The Cyr deposit has a Total Mineral Resource of 110.2 Mt at 1.30% Li2O and a total Ore Reserve of 37.3 Mt at 1.27% Li2O. (See, Arcadium Lithium, formerly Allkem, Press Release dated August 11, 2023)
In the summer of 2023, BRW completed a maiden drill program at the Anatacau property totalling 3,712 meters. 17 of the 18 drilled holes intersected spodumene mineralization.
Other Quebec Projects
James Bay Regional
The James Bay region is prolific for its hard rock lithium endowment, hosting numerous spodumene showings, four deposits with defined resources, as well as more recent discoveries such as Corvette, Adina and Mirage. The James Bay package includes the Mirage, Elrond, Anatacau, Plex and Mythril projects as well many other staked claims with mapped and interpreted pegmatites. The total package includes 4600 claims and 238,042 hectares.
Pontiac
Located 20 to 60 km south of Rouyn, Val-d’or, and Malartic in the Abitibi, Pontiac is a highly prospective region with little previous lithium exploration. The property includes 723 claims and 41,058 hectares. Major S-Type pegmatite fields were identified in the region. Prospecting teams were deployed in the region as part of the 2022 and 2023 lithium exploration campaign. Further prospecting will be conducted in 2024.
North Shore
This claim package is close to year-round road access on the North Shore of the St. Lawrence River, east of the town of Havre St. Pierre. The package contains 333 claims and 18,060 hectares. 30 pegmatite dykes and sills were identified in the area with a minimum strike length of 1,200 meters, as well as dozens of smaller pegmatite dykes. Prospecting teams were deployed in the region as part of the 2022 and 2023 lithium exploration campaign. Many evolved pegmatites were discovered but none contained spodumene. More prospecting will be conducted in 2024.
