Successful A$340k received from SPP following $5m Placement

Ardea Resources Limited (“Ardea” or the “Company”) advises that the Shareholder Purchase Plan (“SPP”) was closed on 30 March 2026. The Company received valid applications from eligible shareholders for 566,667 new shares raising $340,000 with shares to be issued at a price of 60 cents per share (being the same price as the $5m placement[1] ).

Ardea notes that global equity markets continue to experience heightened volatility, driven in part by the ongoing conflict involving Iran and broader geopolitical tensions in the Middle East. These conditions have contributed to increased uncertainty across international financial ‑ markets, impacting investor sentiment and short term trading dynamics. Despite this backdrop, the Company remains focused on executing its strategy and is encouraged by the continued support demonstrated by shareholders through the SPP.

All eligible Ardea Directors, Mathew Longworth, Maree Arnason and Andrew Penkethman participated in the SPP.

As a result, 566,667 new fully paid ordinary shares in Ardea will be issued to shareholders on 7 April 2026 with the new shares to begin trading on 7 April 2026.

Ardea would like to thank all Shareholders for their strong and continued support of the Company.

This announcement is authorised for release by the Board of Ardea Resources Limited.
