North Mining Shares Company Limited has issued a circular convening its annual general meeting (AGM) for 11:00 a.m. on 5 June 2026 at the United Conference Centre, Admiralty, Hong Kong.

Key proposals to be put to shareholders include:

1. Share Issue Mandate • Directors request authority to allot and issue up to 20% of the Company’s issued share capital as at the date of the AGM, equivalent to 3.00 billion shares, assuming the current 15.00 billion shares in issue remain unchanged. • The mandate will remain in force until the earlier of the next AGM, the statutory time limit for holding that AGM, or its revocation by shareholders.

2. Share Repurchase Mandate • Management seeks approval to repurchase up to 10% of issued shares, or 1.50 billion shares, within the same mandate period. • The Company confirms it has made no share repurchases in the six months preceding 23 April 2026. • Directors state they will not exercise the mandate to a level that would materially affect working capital or gearing.

3. Extension Mandate • Subject to the above approvals, the number of shares repurchased may be added to the 20% issue mandate, effectively allowing fresh issuance equal to repurchased shares, capped at an additional 10%.

4. Board Composition • Four directors—Executive Directors Yang Ying Min (Chairman & CEO) and Huang Zhidan, and Independent Non-executive Directors Shek Man Ho and Feng Jia Wei—will retire by rotation and stand for re-election. • Biographical details and remuneration terms are provided in the circular; INEDs Shek and Feng have annual fees of HK$120,000 and HK$50,000 respectively.

5. Administrative Details • The shareholder register will close from 2 June 2026 to 5 June 2026, inclusive. • All AGM resolutions will be voted on by poll in accordance with Hong Kong Listing Rules. • Proxy forms must be lodged with Tricor Investor Services Limited no later than 48 hours before the AGM.

The Board recommends shareholders vote in favour of all proposed resolutions.
