Michael Rowley, SWCM's President and CEO, commented, "Our heartiest congratulations to Heritage Mining for completing their IPO. This achievement is not only an important milestone in our agreement with them but is also one that sets the stage for our mutual success as they advance the Drayton-Black Lake project as their flagship asset. Heritage is off to a great start with a large and highly prospective land package in a producing yet underexplored high-grade district and a team with strong local expertise. gold belt. We expect our agreement with Heritage to be the first in a series of deals whereby we realize significant value for our non-core assets as part of our focus on battery and precious metals at Stillwater West, in Montana's Stillwater Igneous Complex."

Heritage Mining's CEO, Peter Schloo stated, "Completing the IPO is a pivotal moment for Heritage. District-scale exploration assets are very rare, and the project's location in Ontario's producing Rainy River district adjacent to Treasury Metals' Goliath Gold Complex makes it even more compelling. We are well-capitalized and excited about the potential of the Drayton-Black Lake project, and we look forward to reporting on our progress and the targets we have developed there."

About the Drayton-Black Lake Gold Project

The Drayton-Black Lake project consists of over 142 square kilometers in the Abrams‐Minnitaki Lake Archean greenstone belt, along the northern margin of the Wabigoon sub-province in Ontario, Canada. This emerging gold belt has already produced over one million ounces gold¹ and currently hosts 6.6 million ounces of gold in Reserves and Measured and Indicated resources in total among New Gold's Rainy River Mine, Treasury Metals' Goliath Gold Complex, and First Mining's Cameron gold project². Drayton-Black Lake has significant exploration potential with demonstrated high-grade gold in drill results and bulk samples across more than 30 kilometers of underexplored strike in a geologic setting that is shared with Treasury Metals' development-stage Goliath Gold Complex project. Access and infrastructure are excellent on the project, which features direct road access and proximity to rail and power. The project features well-defined, near-term drill targets over four zones, based on over 100 years of exploration data from 176 diamond drill holes totaling approximately 20km that had never been compiled until 2022.
