Cazaly Resources Drills Gulls Blow for First Time Since 1980s Near Old Gold Mines
Key Takeaways
- Cazaly has started RC drilling at Gulls Blow, the first work at the prospect since the 1980s, 90km north of Kalgoorlie in the Goongarrie Gold Project.
- The holes target beneath historical shafts and down-dip of shallow intercepts in GB1, GB2 and GB4, which only reached about 70 vertical metres.
- The 1986 historical results are non-JORC and unverified, so this programme is early-stage validation, not confirmation.
- Cazaly holds 51% of Goongarrie and needs a further $1 million of exploration by March 2029 to reach 80%, with Gulls Blow and Hastings spend counting towards it.
- No results date has been given, though Managing Director Adrian Byass calls the programme short and focused, promising a quick read on depth extensions.
RC drilling commences at Gulls Blow, the first drilling at the prospect since the 1980s
Old mine workings, shallow historical gold intercepts and no follow-up drilling for decades. That is the setup at the Gulls Blow gold prospect, where Cazaly Resources has commenced reverse circulation (RC) drilling within the Goongarrie Gold Project (CAZ 51%, earning up to 80%), 90km north of Kalgoorlie.
The drilling is the first at the prospect since the 1980s. The target sits on the Bardoc Tectonic Zone, immediately southeast of the historical New Boddington and Frank’s Dam gold mines.
The programme follows the historical results first reported by the company on 8 September 2026. It is short and focused, so it should give investors a quick read on whether the shallow grades extend at depth.
Adrian Byass, Managing Director
“Gulls Blow is exactly the kind of target we want to be drilling…”
“…This is a short, focused programme, and it will tell us quickly whether those grades extend at depth.”
Key points from the announcement:
- RC drilling is underway, with the company’s Figure 1 showing the rig on the first hole
- It is the first drilling at the prospect since the 1980s
- The programme is designed to validate and extend shallow historical intercepts beneath old mine workings

What will the drilling test?
Programme design
The initial RC programme is designed to test beneath the historical shafts and down-dip of the shallow historical intercepts in holes GB1, GB2 and GB4. Those historical holes were drilled to a maximum depth of ~70 vertical metres (80m downhole).
A track-mounted RC rig has been mobilised to provide access across the hilly terrain and outcropping quartz veins at the prospect.
The historical results come from Julia Mines NL’s 1986 report (WAMEX A19858). They are non-JORC and a Competent Person has not done sufficient work to verify them, and the company intends to verify them through this RC drilling programme.
Geological setting
The company describes the geology at Gulls Blow as consistent with the sequence hosting the New Boddington and Frank’s Dam pits. Key features include:
- Sheared, chlorite- and carbonate-altered basalt and gabbro
- Cross-cutting faults and sheeted quartz vein sets striking NNW-SSE
- A location 1.5km north along strike of Mason’s Flat
The announcement also includes a location map, a cross-section and a plan of planned collars (Figures 2 to 4) showing proposed drilling against historical holes and mine shafts.
Why does verifying historical exploration results matter?
“Historical, non-JORC” results are older drilling results that were not reported under the JORC Code, the Australian standard for reporting exploration results. Because a Competent Person has not verified them, they cannot be treated as reliable, reportable data.
Re-drilling is how explorers convert that older information into something dependable. RC drilling uses a reverse circulation method, where rock chips are returned to surface for sampling as the hole is drilled.
For you as an investor, this is early-stage validation. Results could support the investment case if they confirm the historical grades, but the outcome is unproven.

What is the Goongarrie earn-in and project backdrop?
Cazaly holds a 51% interest in the Goongarrie Gold Project, earned from Brightstar Resources Limited (ASX: BTR) twelve months ahead of schedule (refer announcement of 27 August 2026). It may increase its interest to 80% by expending a further $1 million on exploration by March 2029.
Expenditure on the Gulls Blow and Hastings RC programmes will contribute towards the final 80% earn-in stage.
| Fact | Detail |
|---|---|
| Interest | 51%, earning up to 80% |
| Further spend | $1 million by March 2029 |
| Project size | 70km² of greenstone |
| BTZ coverage | 20km |
| Location | 90km north of Kalgoorlie |
The project covers 20km of the Bardoc Tectonic Zone, the northern extension of the Boulder-Lefroy Shear Zone, plus two additional subparallel N-S structures identified by subsequent exploration that also have the potential to host significant gold deposits.
The next step is results from the Gulls Blow RC programme. The announcement gives no timeline or results date.
