team, I am pleased to welcome Adrian Karolko as our new Vice President of Exploration. Adrian brings
with him a wealth of experience, including contributions to the Solwezi Project during our early years in
Zambia. We are thrilled to have him return and his extensive expertise gained over the past decade will
complement the efforts of Dr. Kevin Bonel, forming a dynamic technical tag-team advancing our Zambian
assets. I believe the continued expansion of our corporate, technical, and advisory teams with high quality
talent underscores the strength and merits of the projects.
As Adrian steps into his new role, I would also like to extend my sincere appreciation to Robert Sibthorpe
for his outstanding contributions to the company, particularly his role in identifying and securing the
Solwezi Project in 2013. His dedication and expertise have been vital to our progress, and we are grateful
for his continued commitment to consult and advise our technical team.”
