Advancement of Adavale Resources at Ashes Prospect
Adavale Resources (ASX:ADD) is making significant progress on its Ashes Prospect, with advanced geophysical surveys underway to refine high-priority drill targets in a region that shows striking similarities to the nearby Northparkes mine which hosts 5.2 million ounces of gold and 4.4 million tonnes of copper.
Geophysical Surveys Underway to Define Compelling Drill Targets
Adavale has deployed Fender Geophysics to conduct two critical surveys at the Ashes Prospect, located just 12km east of the prolific Northparkes mine in New South Wales. The company is executing:
- A high-resolution ground magnetics survey covering 11.9km² with tight 50m line spacing
- A targeted Induced Polarisation (IP) survey with 4 x 1,600m lines to expand on a previously identified strong chargeability anomaly
These surveys are designed to better define what appears to be a potentially significant copper-gold system that previous explorers, including Meridian Minerals and AngloGold Ashanti, may have inadequately tested.
"Adavale is currently carrying out a ground magnetics survey and most recently commenced an IP survey to better define and expand a previously identified high conviction chargeability anomaly. Following processing of the new IP data and interpretation of the results, Adavale intends to drill test the anomaly," said Executive Chairman and CEO Allan Ritchie.
High-Grade Surface Samples Support Target Potential
What makes the Ashes Prospect particularly compelling is the presence of high-grade surface samples collected near the IP anomaly, including:
| Sample Results | Gold (g/t) | Copper (%) | Silver (g/t) |
|---|---|---|---|
| Sample 1 | 10.65 | 1.98 | 158 |
| Sample 2 | 7.95 | 2.2 | 96.4 |
| Sample 3 | 0.74 | 0.76 | 58.9 |
These surface samples suggest potential for a significant mineralised system beneath the surface, particularly when considered alongside the substantial 50mV/V chargeability anomaly identified in previous IP surveys.
Understanding IP Surveys: Why They Matter for Copper-Gold Exploration
Induced Polarisation (IP) surveys are a sophisticated geophysical technique that measures the chargeability of subsurface materials. This is particularly effective for detecting disseminated sulfide minerals often associated with porphyry copper-gold deposits.
When an electrical current is sent into the ground, certain minerals (especially sulfides like chalcopyrite, a common copper ore) hold or "polarize" the charge briefly before releasing it. This delayed release creates a measurable chargeability response. The 50mV/V anomaly at Ashes is considered strong by industry standards and often indicates concentrations of sulfide minerals that could be associated with economic mineralisation.
For investors, high chargeability anomalies represent potential drill targets that have been identified through scientific methods rather than random exploration, significantly increasing the probability of discovery success.
Multi-Front Exploration Strategy Across the Parkes Project
Adavale is simultaneously advancing multiple initiatives across its Parkes Project:
- London Victoria Mine: Awaiting assay results from a recently completed 14-hole, 2,060m RC drilling program
- Exploration Target Estimation: Working on defining additional potential tonnage and grade beyond the current JORC resource
- Additional Target Generation: Planning geochemical surveys at Parkvale South and reconnaissance work at No Mistake (EL8830), The Dish (EL9711), and Front Gate (EL8831)
The company recently collected 12 rock chip samples from the Corner prospect in mid-August, with assays pending.
Strategic Position in a Tier-1 Mining District
Adavale's Parkes Project comprises five exploration licenses covering approximately 371.39 km² in the highly prospective Macquarie Arc of the Lachlan Fold Belt. This region hosts world-class operations including:
- Cadia Ridgeway: 35.1Moz Au & 7.9Mt Cu
- Northparkes: 5.2Moz Au & 4.4Mt Cu (adjacent to Adavale's tenements)
The project area is positioned along the Lachlan Transverse Zone (LTZ), a crustal-scale structure that hosts both Northparkes and Cadia, significantly enhancing the probability of discovery.
The Importance of Geophysical Data in Copper-Gold Exploration
Modern mineral exploration relies heavily on geophysical techniques to identify potential mineralisation before expensive drilling begins. For copper-gold porphyry systems like those found at Northparkes, the combination of magnetic and IP surveys provides valuable insights:
Ground Magnetics help identify magnetic minerals like magnetite that often occur in porphyry copper-gold systems. These surveys can detect subtle variations in the Earth's magnetic field caused by different rock types and alteration zones associated with mineralisation. By conducting high-resolution surveys with tight 50m line spacing, Adavale can detect features that might be missed in broader regional surveys.
Induced Polarisation is particularly effective for detecting disseminated sulfide minerals that commonly host copper. The strong 50mV/V chargeability anomaly at Ashes suggests a concentration of sulfide minerals at depth that warrant further investigation. By expanding the IP survey north of the existing anomaly, Adavale aims to define the full extent of the potential mineralised system.
The combination of these two complementary techniques provides a much more robust picture of what may lie beneath the surface, allowing for more precise drill targeting and increasing the chances of exploration success.
Why Investors Should Track Adavale Resources
Adavale offers investors exposure to:
- Strategic Location: Operating in a Tier-1 jurisdiction with established mining infrastructure, adjacent to major producing mines
- Multiple Commodities: Primary focus on gold and copper in NSW, with additional exposure to uranium in South Australia and nickel in Tanzania
- Technical Approach: Utilising advanced geophysical techniques to define high-conviction targets prior to drilling
- Near-term Catalysts: Imminent assay results from London Victoria Mine and upcoming drill testing at the Ashes Prospect
With a systematic exploration approach that combines modern geophysical techniques with strong geological understanding, Adavale is methodically building a compelling case for a potential discovery at Ashes. The combination of high-grade surface samples, a strong chargeability anomaly, and a geological setting similar to the nearby Northparkes mine creates a compelling exploration proposition as the company advances toward drill testing.
Diversified Project Portfolio
Beyond the Parkes Project, Adavale maintains a diversified portfolio of exploration assets:
South Australian Uranium Portfolio: The company holds 11 granted exploration licences covering 4,959km² of ground prospective for sedimentary uranium. Seven licences are located in the northern outwash from the Flinders Ranges, with four additional licences east of Ceduna on the Eyre Peninsula.
Kabanga Jirani Nickel Project: In Tanzania, Adavale holds 13 granted licences along the East African Nickel belt. Nine of these licences are proximal to the world-class Kabanga Nickel Deposit (87.6Mt @ 2.63% Ni Eq). The total portfolio covers 1,315km² and was selected based on strong geochemical and geophysical signatures from previous exploration by BHP.
This diversified approach provides shareholders with exposure to multiple commodities and jurisdictions, potentially reducing risk while maintaining significant upside potential across several fronts.
