Westar Resources Unlocks Three Gold Targets at Jerrys Bore
Key Takeaways
- Westar Resources has defined three high-priority gold targets (T1, T2, T3) at Jerrys Bore, each with strike lengths exceeding 2km and coincident gold plus multiple pathfinder element anomalism above the 90th percentile threshold.
- The UltraFine+™ method targets the -2µm clay fraction at 1–3m depth, a deliberate upgrade on Breaker Resources' shallower, coarser-fraction work between 2012 and 2015 that never progressed to drilling.
- Jerrys Bore covers more than 20km of strike along the De La Poer Fault system and has seen virtually no previous drilling on the main project area, leaving the ground largely untested.
- The tenement (E38/4032, 67 blocks) is 100% Westar-owned, granted April 2026, and the project has now graduated to drill-ready status with aircore drilling the confirmed next step.
- A Native Title heritage protection agreement with the Waturta People (WC2018/012) is ongoing and represents a prerequisite before drilling can commence.
Soil sampling unlocks three high-priority gold targets at Jerrys Bore
Assay results from a program of 1,167 UltraFine+™ soil samples at Westar Resources’ Jerrys Bore Project have defined three high-priority gold targets (T1, T2, T3) and a secondary target (T4), all ready for aircore drilling follow-up. The project sits approximately 165km north of Laverton in the Mt Margaret Mineral Field, NE Goldfields of Western Australia, on a single granted exploration licence (E38/4032, 67 blocks, 100% Westar-owned, granted April 2026).
The soil sampling was designed to test for mineralised structures within the poorly exposed Deleta greenstone belt, a section of the Burtville Terrane that has seen virtually no previous drilling.

What is UltraFine+™ soil sampling, and why does it matter?
UltraFine+™ is a geochemical analysis method that targets the finest clay particles in a soil sample, specifically the -2µm clay fraction, rather than the conventional -75µm fraction used in standard soil sampling. That distinction matters because clay particles are far better at capturing the chemical signatures of buried gold deposits in sand-dominated terrain.
Here is why Westar chose this approach over the work done previously by Breaker Resources:
- UltraFine+™ uses the -2µm clay fraction, not the coarser -75µm fraction that Breaker employed
- Samples were collected from 1–3m depth, penetrating below the barren surface layer of aeolian (wind-blown) sand that covers most of the tenement
- Westar’s own orientation survey confirmed the clay fraction is a superior sample medium in this terrain compared to the coarser fraction
- Pathfinder elements targeted included As (arsenic), Bi (bismuth), Mo (molybdenum), Sb (antimony), Se (selenium), and Te (tellurium), all of which are chemical signatures commonly associated with Archean orogenic gold systems (deep-crustal, structurally controlled gold deposits typical of the WA Goldfields)
- Anomalism threshold was set at the 90th percentile across all 1,167 samples, ensuring only genuinely elevated groupings were flagged as targets
Breaker Resources identified low-level gold and arsenic anomalies between 2012 and 2015 but never progressed to drilling. By going deeper and using a finer sample medium, Westar’s program was designed to pick up signals that the earlier, shallower work would have missed.
Three targets defined — what the results show
Target areas were defined only where gold anomalism coincided with anomalous values for at least three pathfinder elements. Each of the three high-priority targets meets that threshold.
Target T1 — northern fault zone
T1 sits in the northern part of the tenement, where low-level gold anomalism is associated with a NNW-trending fault structure running to the west of, and subparallel to, the main De La Poer Fault. The target extends over a strike length of approximately 2km. Gold anomalism is accompanied by elevated pathfinder elements As, Bi, Mo, Sb, and Te, consistent with Archean orogenic gold systems. The anomalism appears to coincide with the intersection of a strip of greenstone rocks (older, volcanic-sequence rocks that host many WA gold deposits) with the NNW-trending fault, a geologically favourable setting. Elevated Cr, Co, and Fe values in the area support the interpretation of mafic (magnesium and iron-rich) rocks at depth.
Targets T2 and T3 — southern greenstone domain
The southern part of the sampled area contains a broader zone of gold and pathfinder element anomalism in an area of greater structural complexity and more probable greenstone rocks.
Target T2 trends roughly NNE for more than 2km, defined by coincident anomalous Au, As, Mo, Sb, and Te values. The target is parallel to a series of minor NE-trending faults in probable greenstone rocks and is likely to extend further north beneath the paleochannel (an ancient buried river system), where gold and pathfinder values drop off sharply at the channel’s edge.
Target T3 strikes roughly north over more than 2km, defined by coincident Au, Bi, and Mo anomalism. It is associated with a curvilinear fault zone that forms a splay off the De La Poer Fault system. An additional anomalous zone at the eastern edge of this area is at least 2km long and remains open to the south, meaning it continues beyond the southernmost sampling line.
Secondary target T4
T4 is a secondary target. It carries no gold anomalism, but elevated values for three pathfinder elements (As, Bi, Te) suggest it may mark a structure that acted as a fluid pathway during past mineralising events. It trends NE and is parallel to the structural grain of the area. Westar considers it worth investigating, but it is clearly lower priority than T1 through T3.
The table below summarises all four targets:
| Target | Strike Length | Orientation | Defining Elements | Priority |
|---|---|---|---|---|
| T1 | ~2km | NNW-trending | Au, As, Bi, Mo, Sb, Te | High |
| T2 | >2km | NNE-trending | Au, As, Mo, Sb, Te | High |
| T3 | >2km (easternmost zone also >2km) | North-striking | Au, Bi, Mo (±Se) | High |
| T4 | Not specified | NE-trending | As, Bi, Te (no Au) | Secondary |

Aircore drilling the next step as Westar advances its NE Goldfields strategy
With three drillable targets now defined, the Jerrys Bore Project has graduated from the geochemistry phase to drill-ready status. Aircore drilling (a shallow, cost-effective drilling method suited to testing buried targets beneath sand cover) may be undertaken across the anomalous areas to test for the presence of buried mineralised structures.
Key context for investors considering the project’s exploration status:
- Jerrys Bore covers more than 20km of strike along and adjacent to the De La Poer Fault, a major NNW-trending structure
- Other than some RAB and aircore holes in the far north of the application area, there has been no previous drilling on the main project area
- The tenement is 100% owned by Westar, in good standing, and was granted in April 2026
- Jerrys Bore is subject to the Native Title claim (WC2018/012) of the Waturta People; discussions regarding a heritage protection agreement are ongoing
Westar’s broader portfolio spans the Yilgarn Craton near Southern Cross, Laverton, and Sandstone in Western Australia, as well as the Birrindudu Basin in the Northern Territory. Jerrys Bore represents the company’s push into an underexplored section of the NE Goldfields greenstone belt, where a single geochemical program has now produced three distinct targets for follow-up work.
