11:08 AM EDT, 07/09/2025 (MT Newswires) -- Brunswick Exploration ( BRWXF ) on Wednesday said it discovered three new major dykes located between 200 meters and 500 meters northeast of MR-6, adding to one identified earlier as part of the 2025 winter drill campaign at its Mirage lithium project, located in the Eeyou Istchee-James Bay region of Quebec.

The company said the "Stacked Dyke" zone was extended 150 meters to the north. Brunswick has discovered a total of four new major dykes measuring between 10 meters and 35 meters, all located near surface and in the core of the project all of which remain open in all directions.

It believes that elevated tantalum concentrations continue to be strongly associated with lithium mineralization with values consistently ranging from 150 parts per million to 350ppm. Brunswick said further metallurgical work will be completed to determine the viability of producing a tantalum byproduct.

Shares of the company were last seen up $0.005 to $0.125 on the TSX Venture Exchange.
