The Nuckulla Hill Project: Strategic Location and Geological Significance

Geographic Position and Gawler Craton Context

The Nuckulla Hill project is located within the Gawler Craton in South Australia, one of Australia's most prolific gold-bearing geological provinces. The Gawler Craton has produced some of Australia's most significant gold discoveries, making it an ideal location for systematic exploration activities.

The region has a proven track record of hosting world-class mineral deposits. Nearby mining operations and discoveries provide a clear geological template for the mineralization styles that can occur in the area. This established mining history reduces exploration risk and provides confidence that economic gold deposits can be discovered and developed in the district.

The Yarlbrinda Shear Zone: 40km of Prospective Ground

The centerpiece of Auravelle Metals' Nuckulla Hill strategy is the Yarlbrinda Shear Zone, a major structural feature extending 40 kilometers in strike length within the company's tenements. Shear zones are classic architectural features known to host economically significant gold mineralization, as they provide the structural conduits through which gold-bearing fluids migrate and concentrate.

The 40-kilometer strike extent of the Yarlbrinda Shear Zone represents an immense exploration target. Unlike most exploration projects that focus on individual prospects measured in kilometers, Auravelle Metals has secured control over four decades of favorable structure. This lengthy structural setting increases the probability of discovering multiple economic deposits or a large, continuous mineralization system.

Neighboring Assets and Regional Validation

Auravelle Metals' Nuckulla Hill project benefits significantly from its proximity to other major gold discoveries in the region:

  • Barton Gold's Tunkillia Gold Project (ASX: BGD) - Located adjacent to Nuckulla Hill, the Tunkillia project hosts 1.6 million ounces of gold, providing strong geological validation of the district's mineral potential.
  • Challenger Gold Deposit - 1.2 million ounces of gold
  • Prominent Hill - A polymetallic discovery containing 1.6 million tonnes of copper, 4.5 million ounces of gold, and 14 million ounces of silver
  • Tarcoola Gold Mine - 30,000 ounces of historical production

These neighboring deposits demonstrate that the Gawler Craton in this region is capable of hosting significant gold mineralization. The presence of Barton Gold's Tunkillia deposit immediately adjacent to Nuckulla Hill provides particularly strong support for Auravelle Metals' geological model and exploration approach.

Recent Exploration Results: Sheoak Prospect Excellence

High-Priority Sheoak Prospect Drilling Results

The Sheoak gold prospect at Nuckulla Hill has emerged as the company's highest-priority target following recent reverse circulation (RC) drilling. The most recent exploration results, announced on January 9, 2026, returned a standout interval of 28 meters at 3.4 grams per tonne of gold (28m @ 3.4g/t Au).

This intersection represents significant exploration success. A 28-meter strike length of continuous gold-bearing rock at approximately 3.4g/t Au indicates a robust mineralized system capable of supporting economic recovery operations. The grade of 3.4g/t Au is well above typical open-pit mining cut-off grades, suggesting that widths of this nature, if repeated and extended, could support future mining operations.

Multiple Prospect Opportunities

While Sheoak has captured the spotlight, Auravelle Metals has defined a portfolio of exploration prospects across the Nuckulla Hill project:

  • Sheoak (primary focus)
  • Sheoak North
  • Sheoak East
  • Bimba
  • Bimba North
  • Bimba West
  • Myall
  • Sauna
  • Arburee

This prospect portfolio provides multiple vectors for discovery across the Yarlbrinda Shear Zone. Not all prospects will develop into significant deposits, but the statistical probability of discovering economic mineralization increases substantially when exploration efforts are spread across multiple targets. Each prospect represents an independent exploration hypothesis, allowing the company to test various geological models and structural interpretations.

Major New Exploration Phase: Detailed Magnetic Survey

Comprehensive Aerial Magnetic Survey Program

A detailed aerial magnetic survey has been commenced to cover the entire 40-kilometer strike extent of the Yarlbrinda Shear Zone. This represents a major commitment to systematic targeting and demonstrates confidence in the prospectivity of the shear zone structure.

The survey specifications are as follows:

  • Total Survey Coverage - 9,400 line kilometers of aerial magnetic data
  • Standard Line Spacing - 25 meters between survey lines across most of the project area
  • Detailed Survey Areas - Selected areas surveyed on 50-meter line spacing for additional detail
  • Data Resolution - Significantly more detailed than the current 200-meter spaced magnetic data

Advantages of Detailed Magnetic Survey Data

Magnetic surveys detect variations in the magnetic properties of rocks beneath the surface. Different rock types and mineralized zones often display distinctive magnetic signatures. By flying at 25-meter line spacing (compared to the current 200-meter spacing), Auravelle Metals will achieve approximately 8 times the data density, allowing for much more precise targeting.

The enhanced resolution will:

  1. Define New Target Areas - Subtle magnetic anomalies that are invisible at 200-meter spacing become apparent at 25-meter spacing, revealing previously unidentified exploration targets 2. Refine Existing Targets - The geometry and continuity of known prospects can be better defined, improving drill-hole planning and targeting accuracy 3. Optimize Drilling Efficiency - By identifying the highest-confidence targets before commencing drilling, the company can direct expensive drilling capital toward the most prospective areas

Integration with Previous Structural Work

The detailed magnetic survey builds upon the company's previous structural targeting review, announced on February 25, 2026. This systematic approach, combining structural analysis with geophysical data, represents a modern best-practice methodology in exploration geology. The structural review identified key fault and shear zone orientations favorable for gold mineralization, which the magnetic survey will now refine with higher-resolution data.

Metallurgical Testwork: Unlocking Recovery Potential

Preliminary Gold Recovery Analysis

Auravelle Metals has commenced preliminary metallurgical testwork on key mineralized intervals from the Sheoak prospect. This work is focused on understanding the recovery characteristics of the gold mineralization.

The testwork program employs bottle roll leaching analysis, a standard metallurgical technique that evaluates how effectively gold can be extracted from mineralized material using leaching reagents. This preliminary analysis is essential for determining:

  • Leaching Efficiency - The percentage of gold that can be extracted under various chemical conditions
  • Processing Parameters - Optimal reagent concentrations, temperature, and contact time for gold recovery
  • Economic Viability - Whether the recovery characteristics support economically viable mining operations

Understanding recovery characteristics early in the exploration phase is crucial. A gold deposit with exceptional grades but poor recovery characteristics may be uneconomic, while a lower-grade deposit with excellent recovery characteristics might support profitable mining. By conducting this work now, Auravelle Metals is ensuring that continued drilling and development decisions are informed by realistic assessments of economic potential.

Structural and Geological Understanding: Televiewer Survey

Down-Hole Televiewer Survey Results

A down-hole televiewer survey has been completed at the Sheoak prospect. Televiewer surveys use sophisticated acoustic tools to create a detailed image of borehole walls, revealing fracture patterns, structural orientations, and rock quality information that would otherwise be invisible from core samples alone.

This survey is particularly valuable because it:

  1. Identifies Structural Controls - Reveals faults, shears, and fractures that host or control mineralization 2. Guides Future Drilling - Provides critical structural information that informs the orientation and positioning of future drill holes 3. Refines Geological Models - Helps geologists understand how mineralization relates to specific structural features

The structural controls identified through the televiewer survey will directly influence the design of the in-fill and extensional RC drilling program planned for late Q1 and early Q2 2026.

Upcoming Drilling Programs: Defining Resources

In-Fill and Extensional RC Drilling

In-fill and extensional RC drilling at the Sheoak prospect is on track to commence in late Q1 or early Q2 2026. In-fill drilling aims to narrow the spacing between existing drill holes, reducing geological uncertainty and better defining the geometry and continuity of mineralization. Extensional drilling targets areas adjacent to known mineralization, testing whether the mineralized zone continues at strike or dips.

This drilling phase is critical for moving from exploration discovery to resource definition. By systematically drilling at closer spacing and extending known mineralization into new areas, Auravelle Metals is building the geological database necessary for a resource estimation.

Discovery-Focused Air-Core Drilling

Beyond the focused work at Sheoak, discovery-focused air-core drilling is scheduled to commence in mid-Q2 2026. Air-core drilling is a rapid, cost-effective drilling method suitable for exploration programs targeting new discoveries. This phase will test the company's expanded prospect portfolio across the Yarlbrinda Shear Zone, using the newly acquired detailed magnetic survey data to guide targeting.

Air-core drilling campaigns often generate the "next discovery," identifying a new area of mineralization that shifts the geological and investment narrative. The systematic approach of first conducting detailed magnetic surveys, then targeting with air-core drilling, represents an efficient exploration methodology.
