"The Board and I would like to record our formal thanks to James for his dedication to Helium One and for the substantial contribution he has made during his tenure as both a Non-Executive Director and Chairman of the Board. Under his stewardship, the Company has progressed through a pivotal phase of its development, evolving from a single-region explorer into a business with a portfolio of two development projects, production and near-term revenues. On behalf of the Board and all employees, I would like to thank James for his service and wish him well in his future endeavours."
