55 NORTH MINING ANNOUNCES WINTER EXPLORATION DRILL PROGRAM AT LAST HOPE GOLD PROJECT

55 North Mining Inc. has released details of its planned 2026 winter drill program at its 100-per-cent-owned Last Hope gold project, located in Manitoba, Canada.

One drill rig is currently mobilized and on site. The winter program is designed as an exploration drill program to test for potential extensions of mineralization to the southeast of the current mineral resource and to improve the company's understanding of the geological controls on mineralization.

"We will focus on stepout drilling designed to test potential extensions of known mineralization and support an updated geological model. The results from this program will guide our plans for an updated mineral resource estimate later in 2026," said Bruce Reid, chief executive officer of 55 North Mining.

Updated resource estimate expected later in 2026

Following the 2025-2026 drill program, 55 North plans to deliver an updated mineral resource estimate later in the year, integrating the new drill results. The previous mineral resource estimate at Last Hope was completed in September, 2021, based on a $1,650-(U.S.)-per-ounce gold price.

Coming catalysts:

• Following completion of drilling: drill results expected in approximately four to six weeks, subject to laboratory turnaround times;
• Later in 2026: updated mineral resource estimate.
