OzAurum Resources Hits Gold with 5m @ 5.37 g/t at Mulgabbie North
OzAurum Resources (ASX: OZM) has delivered impressive high-grade gold results with OzAurum Resources Ltd from its Mulgabbie North Gold Project in Western Australia's Eastern Goldfields. The standout intercepts include 5m @ 5.37 g/t Au and 6m @ 3.68 g/t Au (including 1m @ 10.21 g/t Au).
The latest reverse circulation drilling programme across 10 holes for 660 metres has reinforced the company's transition from explorer to developer. Furthermore, shallow high-grade gold zones have been confirmed across the James, Ben, and Cross Fault Prospects.
The results support OzAurum's staged heap leach development strategy, with metallurgical testwork samples already dispatched to ALS Perth for column leach testing. The company's 260,000 ounce gold resource at 0.70 g/t Au provides a solid foundation for expansion.
However, the Cross Fault discovery just 2km south of the existing resource demonstrates significant growth potential along the 8km Relief Shear corridor.
"These latest results further demonstrate the consistency and continuity of high-grade mineralisation at Mulgabbie North. The intersections from James Stage 1 underpin our initial development plans, while the results from Cross Fault highlight the strong potential to grow the existing 260,000 oz resource base," noted CEO Andrew Pumphrey.
Outstanding Gold Intercepts Across Multiple Prospects
The recent drilling campaign has delivered consistently strong results across three key prospects. Importantly, all holes drilled within the James Stage 1 open-pit area returned excellent grades.
The standout intercepts demonstrate the shallow, high-grade nature of the mineralisation that makes Mulgabbie North attractive for open-pit mining. In addition, these high-grade gold results with OzAurum Resources Ltd continue to validate the company's development strategy.
Key Drilling Results Summary
| Hole ID | Prospect | From (m) | Length (m) | Grade (g/t Au) | Comments |
|---|---|---|---|---|---|
| MNORC 282 | Cross Fault | 25 | 5 | 5.37 | Outstanding high-grade |
| MNORC 278 | Ben | 54 | 6 | 3.68 | Including 1m @ 10.21 g/t |
| MNORC 284 | James | 19 | 7 | 2.46 | Stage 1 confirmation |
| MNORC 277 | James | 28 | 13 | 1.36 | Excellent continuity |
| MNORC 276 | James | 22 | 14 | 1.23 | Longest intercept |
James Prospect Performance Highlights
The James Prospect delivered exceptional consistency across 5 RC holes, each 54m deep on an 8m x 5m pattern. Notably, all holes intersected consistent high-grade gold mineralisation.
These results confirm continuity within the planned open-pit design and support the heap leach development strategy. For instance, the longest intercept of 14m at 1.23 g/t Au demonstrates mineralisation continuity.
Cross Fault Discovery Expansion
Three RC holes continue to confirm the high-grade nature of the Cross Fault discovery. The exceptional 5m @ 5.37 g/t Au represents outstanding shallow mineralisation potential.
The Cross Fault is located on the same Relief Shear as the main resource and positioned 2km south of the existing 260,000oz resource. This proximity suggests significant resource expansion opportunities.
Understanding Heap Leach Gold Processing
Heap leach processing represents a cost-effective method for extracting gold from lower-grade ores. The process uses a chemical solution to dissolve gold from crushed ore placed on specially designed pads.
This technique is particularly attractive for junior miners as it requires significantly lower capital investment compared to traditional processing plants. Furthermore, the scalability makes it ideal for staged development approaches.
Why Heap Leach Matters for Investors
Heap leach technology offers several compelling advantages for investors seeking exposure to gold production:
- Lower capital requirements enable faster project development
- Reduced operational complexity compared to conventional mills
- Shorter permitting timeframes accelerate cash flow generation
- Scalable operations allow staged development and self-funding growth
OzAurum's heap leach strategy at Mulgabbie North is designed for early gold production with a 10-hectare Stage 1 operation. This will be followed by larger 2Mt Stage 2 & 3 facilities.
The company is working with KCCA on site design and layout, whilst metallurgical testwork is already underway. This testing aims to optimise gold recoveries and reagent usage.
Technical Terms Explained
Several technical concepts are crucial for understanding the high-grade gold results with OzAurum Resources Ltd:
RC Drilling: Reverse circulation drilling uses compressed air to bring rock samples to the surface. This provides a cost-effective exploration method for resource definition.
Relief Shear: The main geological structure hosting gold mineralisation at Mulgabbie North. This represents a fracture zone where gold has accumulated over geological time.
Column Leach Testing: Laboratory-scale testing where crushed ore samples are placed in columns. These samples are treated with chemical solutions to determine gold recovery rates.
Development Timeline Accelerating Toward Production
OzAurum has outlined a clear pathway to production with multiple value catalysts scheduled over the coming months. The company's fast-track development strategy is designed to deliver early cash flow whilst building toward larger-scale operations.
Near-Term Development Milestones
December 2024 represents a critical period with several key milestones scheduled:
- Grade control RC drilling on 8m x 5m pattern to optimise pit design
- Metallurgical testwork results from ALS Perth column leach testing
- Site layout and design completion for Stage 1 operations
Q1 2025 will see continued momentum with additional development activities:
- Stage 1 permitting updates and environmental submissions
- Expansion RC drilling at Cross Fault to define maiden resource
- Refined starter-pit model based on grade control results
Development Strategy Overview
| Stage | Size | Location | Status | Timeline |
|---|---|---|---|---|
| Stage 1 | 10ha heap leach | Fast-track permitting | Design phase | 2025 |
| Stage 2 & 3 | 2Mt facility | M28/240 | Planning | Post-2025 |
The Department of Mines fast-track criteria alignment positions OzAurum for accelerated permitting. Moreover, the staged approach enables self-funded expansion from initial production cash flows.
Investment Case: Gold Discovery in Prime Real Estate
OzAurum Resources presents a compelling investment opportunity as a near-term gold producer in one of Australia's premier mining regions. The company's 260,000 ounce resource provides immediate development potential.
Meanwhile, the 8km Relief Shear corridor offers substantial exploration upside within a proven gold system. The recent high-grade gold results with OzAurum Resources Ltd have strengthened the company's position as an emerging developer.
Strategic Advantages
Location Excellence provides significant competitive advantages:
- 130km northeast of Kalgoorlie in established mining region
- 2.5km from Northern Star's Carosue Dam operations
- Proven geological setting with multiple high-grade intercepts
Development Ready Assets support near-term production scenarios:
- Shallow, high-grade mineralisation suitable for open-pit mining
- Existing resource of 260,000oz at 0.70 g/t Au provides foundation
- Staged development strategy minimises capital requirements
Resource Expansion Potential
| Current Resource | Grade | Exploration Upside |
|---|---|---|
| 11.6 Mt | 0.70 g/t Au | 8km Relief Shear corridor |
| 260,000 oz | All categories | Cross Fault discovery |
| 150m depth | 0.3 g/t cutoff | Multiple untested targets |
The Cross Fault discovery with intercepts including 5m @ 5.37 g/t Au demonstrates the potential for significant resource additions. These occur along the same structural corridor hosting the existing resource.
Future drilling will test depth extensions and additional fault-controlled targets to grow the resource base. In addition, the 8km Relief Shear corridor remains largely unexplored.
