"The collective determination of our technical team and board continues to translate into steady progress at Homase. While the pace has been slower than we would have hoped, operations and gold production remain on a positive trajectory and we are all fully aligned and committed to delivering on our production goals. I look forward to updating shareholders over the coming weeks and months as we work to build further momentum through the remainder of 2025."
