Change to Perseus's Senior Management Team

Perseus Mining Limited (ASX/TSX: PRU) announced significant changes to its senior management team on June 10, 2025, with the resignation of Chief Operating Officer Amanda Weir. Weir will officially depart from the company on July 2, 2025, to pursue other opportunities. Throughout her tenure, she has provided invaluable technical and operational expertise, steering Perseus through several challenges and laying the groundwork for future growth.

In the interim, the company has appointed Brett Hartmann, the current General Manager of Operations, to take over responsibilities for operational management. Hartmann has been a part of Perseus since April 2024 and is recognized as a vital member of the senior leadership team. His extensive knowledge of Perseus's assets is deemed crucial for maintaining safe and efficient operations while ensuring that the company meets its production objectives and cost guidance.

Jeff Quartermaine, Managing Director and CEO of Perseus, extended gratitude to Weir for her contributions, emphasizing her role in establishing a strong operational foundation for the company's next growth phase. He expressed well wishes for her future endeavors.

Perseus Mining continues its focus on operational excellence and strategic growth amid these leadership changes, with Hartmann poised to uphold the company’s commitment to safe, steady production. The announcement was officially approved by Quartermaine and reflects Perseus's ongoing adaptability in a dynamic market environment. The company remains committed to its mission, with a robust capital structure comprising approximately 1.36 billion ordinary shares and over 10 million performance rights. For more information, stakeholders can reach out to Investor Relations or Media Relations contacts provided in the announcement.

Perseus Mining Limited's recent change in its senior management team marks a significant juncture for the company and provides investors with essential insights into potential shifts in operational direction and market sentiment. The resignation of Ms. Amanda Weir as Chief Operating Officer introduces a level of uncertainty, but the appointment of Mr. Brett Hartmann as interim COO is a stabilizing factor amid transition.

Mr. Hartmann’s rapid rise to general manager operations and his deep knowledge of Perseus's assets suggest an internal focus on continuity and safety during this period of adjustment. His prior experience will be crucial in guiding the firm through its operational challenges, ensuring that there is no disruption to production levels or cost efficiency. This steady-state operational approach is promising, particularly as Perseus looks to maintain its production and cost guidance during the transition.

The market may initially react with caution to Ms. Weir's departure, given that transitions in top management can lead to uncertainty. Investors should closely monitor production reports and management’s communication in the coming weeks for signs that operations remain on track. Strong performance metrics in these initial months could assuage investor concerns, whereas any slip-up might generate volatility.

Furthermore, investors should watch for updates regarding the search for a permanent COO. A well-chosen successor with the right industry experience and strategic vision could not only reinforce the operational stability but also align with Perseus’s long-term growth objectives.

In summary, while the management shift presents inherent risks, Perseus's proactive leadership approach positions it well for enduring performance. It would be prudent for investors to maintain a watchful eye on operational outputs and strategic plans as the company navigates this transition.
