Notable Quotes
“I am pleased to say that subsequent to the end of Q3 2025 we have successfully mined into sustained 5034‑NEX material and this high‑grade material is running well through the processing plant, which is planned to lead to substantially higher carat production for Q4 2025 and 2026.” – Mark Wall, President & CEO
