Gold / Copper Q1 MRE and Drilling Plans - Telfer South

• Rincon's announces its Q1 2026 project advancement plans for its 100% owned Hasties Main and Hasties SE gold/copper deposit located 10km south of the Telfer gold/copper mine.

• Rincon aims to considerably increase its maiden February 2025 Mineral Resource Estimate (MRE) of 870,000 tonnes @ 0.96 g/t Au and 0.26% Cu (26,800 oz Au and 2,286 t Cu)[1] by incorporating the latest drilling, as announced on 14 November 2025[2] , which included:

• 23m @ 1.05g/t Au from 64m (incl. 9m @ 1.43g/t Au)

• 28m @ 0.95% Cu from 31m (incl. 7m @ 2.5% Cu)

• 12m @ 0.91g/t Au from 32m (incl. 1m @ 3.71g/t Au)

• 38m @ 0.67% Cu from 0m (incl. 6m @ 0.43% Cu & 1m @ 16.3% Cu)

• 4m @ 0.77g/t Au from 24m (incl. 1m @ 2.33g/t Au)

• 25m @ 0.58g/t Au from 24m (incl. 3m @ 1.37g/t Au)

• 11m @ 0.88g/t Au from 106m (incl. 5m @ 1.30g/t Au)

• 18m @ 0.53g/t Au from 33m (incl. 1m @ 1.15g/t Au & 6m 0.6 g/t Au)

• 6m @ 0.44g/t Au from 21m

• Drilling extended the known near surface mineralisation identified in the maiden MRE by ~150m along strike and strengthened the confidence in the mineralization within the resource’s transition zone. Mineralisation remains open along strike and at depth.

• Rincon plans to mobilise a drill rig back to site in early in the quarter to further expand on the gold mineralisation at Hasties and potentially add even further to the project's current MRE.

• This work is a priority now for Rincon and follows on from the multi-stage and multi-year exploration Farm-In and Joint Venture agreement with Greatland Resources (ASX:GGP, AIM:GGP) ("Greatland") on 200.8km[2] of exploration tenements owned by Rincon, as announced on 18 Dec 2026.[3]

• Greatland can ultimately increase its interest in Rincon's exploration tenements to 75% by sole funding to a decision to mine.

• Provisions have been made for Joint Venture ore mined to be toll processed at Greatland’s Telfer mine.

Rincon Technical Director, Michael Griffiths commented:

"With the late December 2025 announcement of the Rincon-Greatland farm-in and joint-venture, Rincon is now well positioned to focus on its wholly-owned Telfer South – Hasties project. This project encompasses the Hasties Main and Hasties South-East gold-copper deposits. Rincon plans to expand the known mineralisation at both sites by pursuing further strike extensions at Hasties Main and exploring untapped extensions at Hasties South-East”.

“In addition, we aim to develop additional gold-copper targets within the project area that were identified during historic exploration but were never pursued by earlier operators, creating new opportunities for growth at Telfer”.

Figure 1 – Telfer South Project Location

Rincon Resources Limited (ASX: RCR) ( “Rincon” or “Company” ) is pleased to provide an update on planned activities for Q1 2026 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 Gold-Copper Mine in Western Australia’s Eastern Pilbara region. (Figure 1)

Following the recent farm-in and joint-venture[3] with Greatland Resources (ASX:GGP), Rincon’s Telfer South – Hasties Project now consists of two exploration licences and two prospecting licences. Together they cover roughly 15 km² and more than 40 km of strike-length across geology known to host substantial gold and copper mineralisation.

Rincon intends to upgrade its February 2025 Mineral Resource Estimate (MRE) that currently stands at 870,000 t at 0.96 g/t Au and 0.26 % Cu (about 26,800 oz Au and 2,286 t Cu)[1] using drilling completed in

Q4 2025[2] . That work extended near-surface mineralisation by approximately 150 m along strike and down-dip into the transition zone, and it confirmed that mineralisation remains open at depth.

Rincon have again contracted Widenbar and Associates to revise the MRE with the aim of having the new MRE published by the end of this quarter.

In early Q1 2026 the company will launch the second phase of extension drilling (pending final statutory approvals). This program aims to further enhance the resources at Hasties Main and Hasties South-East and to explore new opportunities in historic target areas that have not yet received modern exploration attention.

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.
