Drilling Progress Confirms Strategic Objectives
Greenvale Energy's (ASX: GRV) maiden drill program at its 100%-owned Oasis Uranium project in Queensland is advancing steadily, with approximately two-thirds of the planned program now complete. The company has successfully drilled approximately 1,000 meters across seven holes, with five more holes scheduled for completion by mid-September.
The drilling campaign, which commenced in late July, was designed with three key objectives: confirming historical drilling data, extending known mineralization at depth, and testing strike extensions. According to CEO Alex Cheeseman, the program is progressing as planned, with operations being conducted "in a safe and efficient manner."
"Our maiden drill program at Oasis had three key goals – to confirm historical drilling data, to extend the known mineralisation at depth and to extend known mineralisation along strike," Cheeseman said. "With the program now well advanced, we are very pleased with how things have progressed."
The company has completed spectral gamma logging and Acoustic Televiewer (ATV) imaging on the first seven diamond holes, with results currently being interpreted. These advanced techniques provide detailed data on uranium mineralization without waiting for laboratory assays.
Technology-Driven Exploration Approach
Greenvale Energy's Oasis uranium project is employing a multi-faceted approach to evaluate the deposit:
- Spectral gamma logging: Differentiates between uranium, thorium, and potassium
- Acoustic Televiewer imaging: Captures structural features such as fractures and bedding orientation
- Chemical analysis: First drill hole samples have been sent to laboratories in Adelaide
This combination of technologies offers a rapid, cost-effective assessment of the depth, thickness, and concentration of uranium mineralization at the project.
Initial assay results are expected within the next 1-2 weeks, which will help calibrate data generated by the spectral gamma logging. This calibration is crucial for building an accurate understanding of the resource potential.
Understanding Uranium Exploration Technology
Spectral gamma logging is a specialized technique used in uranium discovery exploration that measures natural gamma radiation emitted by rocks in a borehole. Unlike standard gamma tools, spectral gamma tools can differentiate between uranium, thorium, and potassium—the three primary sources of natural gamma radiation.
This differentiation is critical because it allows geologists to identify true uranium mineralization versus other sources of radioactivity. The data collected helps map the distribution and grade of uranium without waiting for laboratory assays, accelerating the exploration process significantly.
| Technology | Function | Benefit to Exploration |
|---|---|---|
| Spectral Gamma Logging | Measures and differentiates gamma radiation sources | Identifies uranium vs. other radioactive elements |
| Acoustic Televiewer | Images borehole walls to capture structural features | Maps fractures that may control mineralization |
| Chemical Analysis | Laboratory testing of core samples | Provides definitive grade data for resource calculations |
Regional Exploration Reveals Broader Potential
Beyond the current drill program, Greenvale has conducted reconnaissance mapping and sampling across regional targets surrounding the Oasis deposit. The results suggest significant potential for the broader project area.
Of 33 rock chip samples collected, 16 returned grades greater than 10ppm uranium, and 5 samples exceeded 30ppm uranium. The most significant result came from a diorite dyke located approximately 4.5km northeast of the Oasis deposit, which returned 187.4ppm uranium.
This finding is particularly encouraging as it indicates the potential for a much larger mineralized system beyond the immediate Oasis deposit area. The company has already followed up with additional sampling to better define this anomaly.
Remaining Program Objectives
The five remaining drill holes in the program are strategically designed to:
- Test northernmost extensions beyond the current known mineralization
- Confirm continuity of mineralization within the deposit
- Assess potential for additional mineralization at depth
Drill holes 25GRV11 and 25GRV12 specifically target deeper positions beneath known mineralization, which could significantly expand the resource potential if successful.
Why Investors Should Follow Greenvale Energy
Greenvale Energy's Oasis uranium project represents an opportunity for investors seeking exposure to the uranium sector at a time when nuclear energy is gaining renewed attention as a clean energy source. The company's Oasis project offers several compelling investment attributes:
- Advanced-stage exploration: With historical data and ongoing validation, the project is well beyond grassroots exploration
- Expanding footprint: Both depth and strike extension drilling could significantly increase the resource potential
- Regional upside: New discoveries 4.5km from the main deposit suggest a larger mineralized system
- Strong technical approach: The use of multiple technologies demonstrates a sophisticated exploration strategy
- Clear timeline: Results expected within weeks, providing near-term catalysts
For investors tracking the uranium sector, Greenvale's systematic approach to expanding and defining the Oasis deposit, combined with promising regional exploration results, positions the company as a noteworthy player in Australia's uranium exploration landscape.
The company expects to complete the current ambitious drilling program by early-to-mid September, with a steady flow of results to follow as laboratory analyses are completed and interpreted.
Additionally, the innovative techniques used at Greenvale's Oasis uranium project share similarities with in-situ recovery trials being tested in other critical minerals projects globally. Furthermore, the company's methodical approach to resource definition aligns with industry best practices seen in recent major drilling programs focused on establishing JORC-compliant resources for critical minerals.
