Normandy Minerals Grab Samples Return 13.9 g/t Gold at Halleys Stockpile
Key Takeaways
- Two grab samples from a historical stockpile at Halleys East returned 13.9 g/t Au (15.8 g/t on lab repeat) and 1.68 g/t Au, but the company says they are not representative of the stockpile and cannot support grade or tonnage estimates.
- Core Geophysics identified six priority targets at Halleys, four of them in areas with limited prior testing, though the fault interpretation is tentative and no link to gold has been established.
- First Halleys East diamond assays are due within 2-3 weeks, with a ~6,000m RC program targeting high-grade infill and extensions expected to start in mid-October.
- Halleys East was mined to 2014 at a reported average grade above 8 g/t Au, per the SRK Independent Geologist's Report in the prospectus.
- Normandy owns 100% of every Halleys tenement with no royalties, but systematic stockpile sampling has no timing beyond an update 'in due course'.
Stockpile samples return up to 13.9 g/t Au as geophysics sharpens Halleys targets
On 13 October 2026, Normandy Minerals (ASX: NMD) reported assay results from two grab samples of a historical gold stockpile at its Halleys Project, grading 13.9 g/t Au and 1.68 g/t Au. A geophysical review by Core Geophysics also identified six priority areas for further assessment.
Both items feed a near-term pipeline of diamond assays and RC (reverse circulation) drilling. Here is what the announcement said, and what it deliberately did not.
Key points from the announcement:
- Structural targets at Halleys were refined by a review of historical magnetic and radiometric data
- Six priority areas were identified, four of them in areas with limited prior testing
- Stockpile mineralisation was confirmed by two reconnaissance grab samples
- Drilling news flow is expected, with first diamond assays anticipated within 2-3 weeks

“The preliminary stockpile results are highly encouraging we remain focused on our strategy of de-risking the Halleys District…”

Stockpile sampling confirms mineralisation next to the Halleys East pit
Normandy completed preliminary sampling of a remnant stockpile adjacent to the Halleys East pit. The Mine Closure Plan (MCP) ID 60029 noted that a low-grade stockpile remained on site, but gave no specific volumes or potential grades.
Normandy believes the stockpile it sampled is the material referenced in that plan.
What the grab samples returned
Two reconnaissance grab samples, each of approximately 2.5 kg of selected rock fragments, were collected from separate surface locations. Samples were submitted to Bureau Veritas Minerals Perth and assayed by 40 g fire assay with an AAS finish.
| Sample No. | Easting / Northing (GDA2020 / MGA Z50) | Gold Assay (g/t Au) | Lab Repeat Gold Assay (g/t Au) |
|---|---|---|---|
| PT163878 | 703296 / 6737352 | 1.68 | Not Assayed |
| PT163879 | 703282 / 6737343 | 13.9 | 15.8 |
The coordinates mark collection points on disturbed stockpiled material, not in-situ mineralisation. The repeat assay for PT163879 supports the initial result, though no independent verification of the assays has been completed.
Why the caveats matter
Two samples cannot describe a whole stockpile, and the company says so plainly.
Cautionary Statement – Stockpile Sampling
“Grab samples are selective by nature and may not be representative of the material sampled. The assay values of 1.68 g/t Au and 13.9 g/t Au should not be considered representative of the stockpile as a whole and should not be used as the basis for estimating grade, tonnage or contained metal.”
For you as an investor, that means the results confirm that gold is present, nothing more. The values have not been averaged, and no resource is implied.
The next step is a systematic sampling program to assess grade distribution, variability and “potential monetisation pathways”. No timing was given beyond an update “in due course”.
Geophysical review defines six priority targets
Understanding geophysical targeting
Airborne magnetic and radiometric surveys measure variations in the magnetic properties and natural radioactivity of rocks from an aircraft. The data can reveal faults, rock boundaries and other structures even where surficial cover hides the geology at surface.
That matters because, according to the announcement, structural intersections and the margins of intrusive bodies are recognised as important controls on gold mineralisation in many Yilgarn gold systems. Mapping them helps decide where to drill.
Normandy’s cover is a real constraint here. Surficial cover across parts of the project obscures surface expressions of the underlying geology, so geophysics fills a gap that surface sampling cannot.
What Core Geophysics found
The review consolidated two historical airborne aeromagnetic surveys, completed in 2002 and 2010-2011 at 100m and 50m line spacings respectively. Its main findings:
- Six priority targets and several secondary targets were identified.
- Two priority targets cover the named Prince and Phil zones.
- The remaining four cover areas not previously evaluated to any extent.
- Northeast-southwest trending faults appear to partition north-northeast-south-southwest oriented structures within the volcanic sequence.
- Several sub-circular, non-magnetic features near Halleys East are interpreted as possible late felsic intrusive bodies.
Two caveats apply. The interpreted fault hierarchy is tentative and requires further definition from current drilling, logging and structural observations. And no temporal or genetic relationship between the interpreted intrusions and gold mineralisation has been established to date.
Management said the interpretation is being integrated with current diamond drilling and will assist in prioritising targets for the planned RC program.

Near-term catalysts and next steps
Normandy listed the following near-term priorities:
- First Halleys East diamond assays, anticipated within 2-3 weeks
- Completion of the ~2,000m diamond program, including structural holes across the broader Halleys district
- A ~6,000m RC drilling program targeting high-grade infill and extensional targets at the historic Halleys East Pit, expected to commence in mid-October
- Systematic sampling of the historical stockpile
- Continuing greenfield geochemical sampling and geophysical studies in parallel with drilling
Historical mining at Halleys East was completed in 2014, with a reported average mined grade exceeding 8 g/t Au. That information is extracted from the SRK Consulting Independent Geologist’s Report in the company’s prospectus.
Normandy owns 100% of each Halleys tenement, and there are no royalties. Conner said the company plans to provide regular market updates as drilling progresses.
