Private Shareholder Drinks & Q&A with CEO

Alex Walker, CEO of East Star (LSE: EST), the Kazakhstan-focused gold and copper exploration and development company, invites private shareholders for drinks and Q&A in central London on Thursday, 11 June 2026 at 2.45 p.m. BST.

East Star is advancing a portfolio of high-quality copper and gold projects across Kazakhstan, anchored by a maiden JORC mineral resource estimate of 20.3Mt at its Verkhuba VMS copper development in an infrastructure-rich region, as well as a strategic joint venture with Endeavour Mining targeting major gold discoveries.

The occasion is a chance to discuss how East Star is progressing these projects towards meaningful value inflexions, with strong exploration pipelines across its VMS and porphyry assets, and a copper JV agreement recently signed with Xinhai Mining adding further momentum to the Company's growing portfolio.

Attendance is strictly by RSVP. Please email eaststar@vigoconsulting.com to register your attendance and to be provided with details of the location.
