Arika Resources Strikes Gold: 20 New High-Priority Targets Transform Yundamindra South
Arika Resources Limited (ASX: ARI) has delivered a game-changing breakthrough at its Yundamindra Gold Project by Arika Resources Ltd, with high-resolution magnetic surveying uncovering 20 new high-priority exploration targets across the previously unexplored Yundamindra South area. This revelation expands the Company's exploration footprint across 50% of its total project area – territory that has remained untouched by modern systematic exploration despite extensive historical prospector workings.
The magnetic survey results reveal a structurally complex intrusive volcanic and granitic interaction with intense structural disruptions – the exact geological signature consistently associated with multi-million-ounce gold deposits throughout the region. Located just 65km southwest of Laverton in Western Australia's world-class northeastern goldfields, Yundamindra sits within striking distance of Sunrise Dam (8 million ounces) and Wallaby (7 million ounces) – two of Australia's premier gold mines.
"The acquisition of this new, high-resolution TMI dataset over Yundamindra South is like flicking on a light switch – we can now see with great clarity the geological structures that control the mineralisation, providing Arika with an immediate pipeline of 20 new targets for follow-up exploration." Justin Barton, Managing Director

Understanding Total Magnetic Intensity (TMI) Surveys: The Gold Hunter's X-Ray Vision
Total Magnetic Intensity (TMI) surveys represent one of the most powerful tools in modern mineral exploration, functioning like geological X-ray vision for subsurface structures. This geophysical technique measures variations in Earth's magnetic field caused by different rock types, revealing hidden geological architecture beneath surface cover.
Why TMI Surveys Are Critical for Gold Discovery
For gold exploration, TMI surveys are particularly valuable because they identify structural corridors and fault intersections where gold-bearing fluids historically flowed. Furthermore, they map granite-greenstone contacts – prime locations for orogenic gold deposits.
Additionally, TMI surveys detect magnetic intrusive bodies that may host copper-nickel-PGE mineralisation. Moreover, they reveal deformation zones and shear systems critical for gold concentration.
Technical Process: TMI surveys work by measuring tiny variations in magnetic field strength caused by different rock types. Granite typically shows low magnetic readings, whilst iron-rich rocks produce high readings. When these contrasting rock types meet along fault zones, they create ideal conditions for gold formation.
Why This Matters to Investors: TMI surveys dramatically reduce exploration risk by providing a geological roadmap before expensive drilling begins. At Yundamindra South, this technology has transformed a blank canvas into a precise target map, significantly improving the probability of discovery success.
Three Proven Exploration Models Drive Target Portfolio
The geological team at the Yundamindra Gold Project by Arika Resources Ltd has categorised the 20 new targets into three distinct, regionally-validated exploration models. Each model represents a different geological environment with proven potential for significant mineral discoveries.
Granny Smith/Tarmoola-Style Gold Targets
Target Focus: Shear zones and structural complexity hosted entirely within granite
Regional Precedent: Granny Smith mine (multi-million ounce producer)
Key Targets: YS1, YS2, YS18 – structural intersections within competent granite
This model targets areas where intense fracturing within granite rocks has created pathways for gold-bearing fluids. The process occurs when massive granite formations experience stress and cracking, allowing hot, mineral-rich fluids to flow through and deposit gold along fracture zones.
Pennyweight Point-Style Gold Deposits
Target Focus: Structural intersections on or near granite-greenstone contacts
Local Success: Proven at Yundamindra North with exceptional drill results
Key Targets: YS3, YS5, YS17 – high-rheological contrast margins
These targets focus on boundary zones where granite meets greenstone rock formations. The contrast between these different rock types creates natural weak points where gold-bearing solutions can concentrate, forming high-grade deposits.
Magmatic Copper-Nickel-PGE Potential
Target Focus: Late-stage structurally emplaced mafic/ultramafic bodies
Commodity Diversification: Expands beyond gold into battery metals
Key Targets: YS6, YS7, YS8, YS10 – magnetic intrusive bodies along major shears
This model targets areas where molten rock rich in copper, nickel, and platinum group elements (PGEs) was injected along existing fault systems. These intrusions can form deposits containing valuable battery metals alongside precious metals.
| Target Priority Breakdown | |
|---|---|
| High Priority | 8 targets (YS3, YS5, YS6, YS7, YS8, YS10, YS14, YS18) |
| Moderate-High Priority | 6 targets (YS2, YS4, YS16, YS17, YS19, YS20) |
| Moderate Priority | 6 targets (YS1, YS9, YS11, YS12, YS13, YS15) |
Strategic Timeline Positions Arika for Discovery Success
The Company has outlined a systematic approach to target evaluation and drilling, with clear milestones extending into 2026. This methodical progression demonstrates management's commitment to maximising exploration success whilst managing risk effectively.
Immediate Phase (Q4 2025)
Complete ongoing drilling at Pennyweight Point testing down-plunge extensions. Process assay results from 31 holes across 17,000 metres of completed drilling.
Early 2026 Phase (Q1 2026)
Commence surface geochemical surveys across amenable target areas. Additionally, initiate regulatory approval processes for drilling permits. Begin ground-based geophysical surveys for target refinement.
Mid-2026 Development
Launch maiden drilling programme targeting highest-priority prospects. Test structural intersections and granite-greenstone contacts. Expand successful discoveries with step-out drilling.
Yundamindra South represents almost 50% of the total project area yet remains unexplored – providing exceptional discovery leverage from a relatively modest investment in systematic exploration.
Investment Thesis: World-Class Address Meets Untested Territory
Arika Resources has positioned itself at a unique intersection of proven geological potential and unexplored discovery upside. The Yundamindra Gold Project by Arika Resources Ltd location within the Laverton Greenstone Belt – a district that has produced over 28 million ounces of gold – provides the geological validation typically sought by institutional investors.
What Makes This Investment Compelling?
Tier-1 Location Advantage
Located 20-30km from Sunrise Dam and Wallaby mines. Access to established mining infrastructure and processing facilities. Proven district-scale mineral systems with demonstrated production history.
