RINCON RESOURCES LIMITED — Capital/Financing Update 2026

Feb 1, 2026

2[nd] February 2026

Telfer South Drilling Approvals Awarded

• Drilling Approvals received for the 100% Rincon owned Hasties Main and Hasties SE gold/copper deposits located 10km south of the Telfer gold/copper mine.

• Rincon now plans to mobilise a drill rig back to site later in the quarter to further expand on the gold mineralisation at the Hasties Main and Hasties SE deposits and increase the MRE.

• Several anomalies identified by Newmont and Newcrest during the 1980’ and 1990’s have now been identified and will be verified on ground when site activity resumes in the coming weeks.

• Having finalised the Farm-In and Joint Venture[1] agreement (December 2025) with Greatland Resources (ASX:GGP, AIM:GGP) ("Greatland") on 200.8km[2] of exploration tenements, Rincon can now concentrate its efforts on the Hasties prosect that hosts the Hasties Main and Hasties SE gold/copper deposits.

• Revised Mineral Resources Estimate still on target for end of Q1.

ASX Announcement 2nd February 2026

Rincon Resources Limited (ASX: RCR) ( “Rincon” or “Company” ) is pleased to advise that all permits have been approved for the next drill program at its wholly owned Telfer South - Hasties Project that hosts the Hasties Main and Hasties South-East gold-copper deposits situated 10km south of the Telfer GoldCopper Mine in Western Australia’s Eastern Pilbara region. (Figure 1)

Following the finalising of farm-in and joint-venture with Greatland Resources (ASX:GGP), Rincon’s Telfer South Project – Hasties prospects now comprises two exploration licences and two prospecting licences. Together these licences cover approximately 15 km² with several parallel structures across geology known to host significant gold and copper mineralisation.

The programme’s goal is to further increase the resources at Hasties Main and Hasties South-East while also investigating historic target areas identified by Newmont and Newcrest during the 1980’ and 1990’s that have yet to receive modern exploration focus.

Rincon plans to upgrade its February 2025 Mineral Resource Estimate (MRE), which currently stands at 870,000 t grading 0.96 g/t Au and 0.26 % Cu (roughly 26,800 oz Au and 2,286 t Cu)[2] , using drilling completed in Q4 2025 (Annexure A). This work extended near-surface mineralisation by about 150 m along strike and down-dip into the transition zone, confirming that the deposit remains open at depth.

Rincon has once again engaged Widenbar and Associates to revise the MRE, targeting publication of the updated estimate by the end of this quarter.

About Rincon:

Rincon has 100% interest in four exploration assets in Western Australia that are highly prospective for copper and gold. These are the South Telfer Project, Crackerbox Gold Project (Murchison Gold Field), West Arunta Project and the Laverton Project.

Each asset has previously been subject to historical exploration which has identified prospective mineral systems that warrant further exploration. The Company’s aim is to create value for its shareholders by advancing its assets through the application of technically sound, methodical, and systematic exploration programs to test, discover, and delineate economic resources for mining.
