Rincon Resources Ltd Telfer South Expansion Unveils Kilometre-Long Mineralisation

Historic Data Unlocks Massive Expansion Potential at Rincon's Telfer South Gold-Copper Project

Rincon Resources Ltd Telfer South expansion has captured significant attention following a comprehensive review of historic exploration data that has dramatically enhanced the project's potential. The company's analysis of data originally collected by Newcrest Mining in 1991 has revealed extraordinary opportunities for resource growth at the Hasties prospect.

This groundbreaking discovery has transformed understanding of the mineralisation system, extending the known strike length from 700 metres to over 1,000 metres. Furthermore, the identification of high-grade samples returning up to 37 g/t gold and 21% copper underscores the project's exceptional potential in Western Australia's resource-rich landscape.

Discovery Transforms Hasties Prospect from 700m to Over 1km Strike Length

Rincon Resources Limited (ASX: RCR) has unveiled significant progress at its 100% owned Telfer South project following a thorough review of historic exploration data. This analysis has identified a major extension of the gold-copper system at the Hasties prospect, which now spans over 1,000 metres in strike length.

The most significant development involves the identification of the Hasties Central zone, an area situated between the previously defined Hasties Main and Hasties Southeast (SE) deposits. Historic rock-chip samples indicate the presence of high-grade mineralisation, with values reaching 37 g/t gold (Au) and 21% copper (Cu).

The potential continuity between Hasties Main and Hasties SE enhances the scale of mineralisation considerably. Moreover, this discovery lays the groundwork for substantial resource growth as the Rincon Resources Ltd Telfer South expansion programme advances.

Key Investment Highlights

The project presents compelling investment fundamentals across multiple metrics:

• High-grade historic samples: Assayed up to 37 g/t Au and 21% Cu
• Hasties Central discovered: Extends for over 300 metres along strike and up to 100 metres wide
• Total mineralised trend length expanded: Now exceeding 1 kilometre, remaining open along strike
• Current foundation resource: 26,800 ounces of gold supported by an 870,000-tonne resource at 0.96 g/t Au
• Planned drilling: A major exploration campaign is set for 2026 to confirm the enlarged system

Michael Griffiths, Rincon's Technical Director, commented:

"This discovery fundamentally shifts how we view the Telfer South project. The integration of historic data not only confirms the high-grade nature of the Hasties mineralisation but also demonstrates continuity between key zones."

What Rock-Chip Sampling Reveals About Gold-Copper Potential

Rock-chip sampling represents an essential and cost-efficient exploration technique frequently utilised in early-stage mineral exploration. By analysing rock fragments collected from exposed outcrops, researchers can assess the potential for further mineralisation at depth.

Unlike drilling, which requires more substantial resource investment, rock-chip sampling provides a rapid, scalable method to identify prospective drill targets. Consequently, this approach allows companies to cover broader areas whilst maintaining cost-effectiveness.

Why Rock-Chip Results Are Critical

The significance of rock-chip sampling extends across several key areas:

• Indicator of subsurface potential: Rock chips reflect surface expressions of what may lie below
• Defining mineral trends: Patterns in grades from rock-chip data help delineate zones for focused drilling
• Cost-effectiveness: Rock-chip exploration costs significantly less than drilling programmes
• Validation through history: Systematic surveys by established operators like Newcrest provide significant confidence

At Hasties Central, 163 rock-chip samples were collected and analysed using industry-standard methods. These included fire assays for gold and atomic absorption spectroscopy for copper, ensuring reliable results for the Rincon Resources Ltd Telfer South expansion evaluation.

Sample Verification Details

The comprehensive verification process included several critical components:

• Sampling supported by 1:20,000 geological mapping for spatial accuracy
• Certified laboratory analysis completed with oversight by Australian Laboratory Services
• Data verification and digitisation by geological consulting group Apex Geoscience
• High-grade results, particularly those exceeding +30 g/t Au, building confidence in the robust mineralised system

This historic dataset now enables Rincon to refine its geological model effectively. Additionally, it confirms Hasties Central as a priority area for the 2026 drilling programme.

Proximity to Established Mining Infrastructure Supports Development

The strategic location of the Telfer South project provides significant advantages for future development. Positioned approximately 10 kilometres southwest of Newcrest's Telfer Gold Mine, the project benefits from proximity to world-class mining operations.

Telfer Mine has produced over 7 million ounces of gold since its inception, demonstrating the regional potential for additional deposits. Furthermore, existing infrastructure including transport networks and processing facilities creates notable synergies for future exploration and development activities.

The farm-in agreement with Greatland Resources (ASX: GGP) adds substantial value to the Rincon Resources Ltd Telfer South expansion strategy. Under this agreement, Greatland will contribute £15 million in exploration funding across four years whilst bringing technical expertise from its involvement in the nearby Havieron deposit.

Upcoming Drilling Campaigns (2026)

The structured drilling programme encompasses several key phases:

• Q1 2026: Drill rigs to be mobilised to the Hasties Central zone
• Q2-Q3 2026: Systematic drilling covering Hasties Main, Hasties SE, and Central zones
• Q4 2026: Anticipated resource updates incorporating new intercepts from Hasties Central
• Beyond 2026: Potential regional scale exploration, targeting nearby prospects

The current resource of 870,000 tonnes at 0.96 g/t Au and 0.26% Cu forms a strong baseline. However, these developments are expected to herald substantial growth in measured resources.

Financial Strength Enables Aggressive Exploration Strategy

With financial backing largely provided by Greatland's expansive commitment and Rincon's own 100% ownership of multiple licences, the company demonstrates a solid position to pursue aggressive exploration. This funding model ensures shareholders retain full exposure to the upside potential of any resources defined during the 2026 campaign.

The financial structure provides several key advantages for investors. Firstly, the farm-in agreement reduces dilution whilst maintaining exploration momentum. Secondly, Rincon's full ownership ensures maximum value capture from successful discoveries.

Resource Potential and Growth Objectives

A comparison of current resources versus potential resources at Telfer South underscores the scale of opportunity at Hasties Central:

The historic data at Hasties Central exhibits significantly higher gold and copper grades than those seen within the existing resource model. Therefore, this reinforces the strong case for resource expansion as the Rincon Resources Ltd Telfer South expansion programme progresses.

Michael Griffiths noted:

"Our collaboration with Greatland ensures we have the financial flexibility and geological expertise required to systematically unlock the full potential of these tenements. Investors can expect consistent news flow from our structured drilling campaigns well into 2027."
