CGN Mining Company Limited released a supplemental announcement on 2 June 2026, addressing its ongoing non-compliance with Rule 13.92(2) of the Hong Kong Listing Rules following the resignation of former director Ms. Xu on 13 February 2026.

The company reiterated that, since Ms. Xu’s departure, it has been actively searching for a qualified female candidate whose profile satisfies multiple diversity criteria, including gender, age, cultural background, educational qualifications, professional expertise, and industry or regional experience.

Management noted two key impediments to a prompt appointment: 1. A limited pool of female candidates possessing the requisite skill set. 2. Additional policy, background-check, and multi-level approval requirements applicable to state-owned enterprises.

Despite these challenges, the Board expects to appoint an eligible female director “as soon as practicable,” with a target timeframe of three months from the 14 May 2026 announcement date.

Current Board composition (as of 2 June 2026) remains: • Non-executive Director: Mr. Wang Xianfeng (Chairman) • Executive Directors: Mr. Qiu Bin (Chief Executive Officer) and Mr. Li Jie • Independent Non-executive Directors: Mr. Gao Pei Ji, Mr. Zhang Yuntao and Mr. Wu Yingpeng

Further announcements will be issued once the new appointment is confirmed, ensuring compliance with the diversity requirements of the Hong Kong Listing Rules.
