Bulgera Drilling Yields 5m at 3.9g/t Au from 238m, Resource Update Imminent
Norwest Minerals has reported robust gold assay results from its Phase 2 drilling at the Bulgera Gold Project, confirming mineralisation continuity at depth and setting the stage for a resource upgrade.
- Phase 2 RC drilling confirms gold mineralisation continuity below 200m
- Notable intercept – 5m at 3.9g/t Au from 238m depth
- Upcoming updated Mineral Resource Estimate expected late Q1 2026
- Metallurgical testwork underway for low-cost heap leach operation
- Price-Mercuri gold trend remains open for further resource growth
Strong Results Reinforce Bulgera’s Depth Potential
Norwest Minerals Limited (ASX – NWM) has delivered encouraging results from its Phase 2 Reverse Circulation (RC) drilling program at the Bulgera Gold Project in Western Australia. The recent assays confirm that gold mineralisation extends well below previously tested depths along the Price-Mercuri trend, a key structural zone within the project.
Among the standout results, Hole 25018 intersected 5 metres grading 3.9 grams per tonne (g/t) gold starting at 238 metres downhole, including a higher-grade 1 metre interval at 9.3 g/t. Other holes returned consistent mineralised widths and grades, reinforcing the geological continuity of the system at depth.
Strategic Drilling Targets and Geological Consistency
The Phase 2 drilling was designed to test downdip extensions and infill areas within the existing Mineral Resource Estimate (MRE) footprint. The results align with the geological model, which describes a sequence of amphibolites and felsic volcanics hosting gold mineralisation associated with sulphides and quartz veining. The mineralised zones dip approximately 35 degrees northwest, and the drilling confirms strong continuity, supporting potential resource classification upgrades.
Norwest’s CEO, Charles Schaus, highlighted the significance of these findings, noting that the grades and widths encountered are particularly encouraging amid the current elevated gold price environment. The confirmation of mineralisation at depth bolsters confidence ahead of the planned MRE update.
Looking Ahead – Resource Update and Metallurgical Testing
The company is integrating data from both Phase 1 and Phase 2 drilling campaigns into an updated geological model, with a revised Mineral Resource Estimate expected by late Q1 2026. Concurrently, metallurgical testwork is progressing on bulk oxide samples to assess the amenability of the ore to a low-cost heap leach processing method, a critical step in advancing project economics.
Additionally, Norwest anticipates imminent assay results from exploration drilling at its nearby Marymia East project, which could further enhance its regional gold portfolio.
Implications for Investors and the Project’s Future
The confirmation of robust gold mineralisation at depth and the open-ended nature of the Price-Mercuri trend suggest significant upside potential for resource growth at Bulgera. The combination of solid grades, geological continuity, and advancing metallurgical studies positions Norwest well to capitalise on favourable market conditions and progress towards development.
Bottom Line?
Norwest’s deep drilling success at Bulgera sets a promising foundation for a resource upgrade and potential low-cost gold production.
Questions in the middle?
- How will the updated Mineral Resource Estimate impact Norwest’s valuation and project economics?
- What are the expected recovery rates and costs from the upcoming heap leach metallurgical testwork?
- Could exploration success at Marymia East complement and enhance Norwest’s regional gold strategy?
