EXTENSIVE GREENLAND LITHIUM EXPLORATION CAMPAIGN LAUNCHED BY BRUNSWICK EXPLORATION

Brunswick Exploration Inc. has launched an aggressive regional-scale prospecting and mapping initiative on its sizable Greenland portfolio that contains hundreds of untested targets using four crews and two helicopters for six weeks.

Initially, one team will focus on detailed mapping and sampling around the Ivisaartoq spodumene discovery and surrounding areas while the other will focus on the expanded Nuuk and Paamiut licences as well as the historical spodumene showing at Paamiut. Starting in July, one team will focus on follow-up prospecting at the Nuuk and Paamiut projects based on results from June while the other team will focus on the Disko Bay and Uummannaq projects. Results from the first six weeks will be used to plan advanced exploration programs in August and September, 2025, including first-pass prospecting across its recently acquired Hinksland project in eastern Greenland (see news release of March 13, 2025).

Killian Charles, president and chief executive officer, commented: "This is a very exciting step for Brunswick Exploration as we look to significantly increase our exploration initiative in Greenland alongside our Quebec projects. As a reminder, we have consolidated nearly all accessible lithium targets in Greenland following our first-mover advantage. There is substantial exploration potential in Greenland and BRW is one of the few companies actively exploring in the country.

"Over the last four years, we have built an internal lithium expertise for grassroot exploration that is unique across the sector and our peers. There are many more opportunities that exist as BRW is best positioned to uncover new discoveries across our portfolio and beyond."
