British King Gold Project: Filing of NI43-101 Technical Report

Executive Summary

• Central Iron Ore Limited filed a NI 43‑101 technical report updating the British King Gold Project’s mineral resource estimate.
• The updated resource totals 311,800 tonnes at an average grade of 6.20 g/t Au, containing approximately 62,200 ounces of gold (Indicated: 227,300 t @ 5.78 g/t = 42,200 oz; Inferred: 84,500 t @ 7.36 g/t = 20,000 oz).
• The report confirms increased geological and grade confidence and indicates the mineralisation is amenable to standard carbon‑in‑leach processing, supporting future mining proposal work.
