Key Highlights

  • Bulletin Resources (ASX:BNR) reported on 31 July 2026 that exploration programs have started at the Lake Rebecca Gold Project, including dipole-dipole IP, gravity and ultrafine soil surveys.
  • Results from three drill holes at Chifley confirmed anomalous gold in transported cover, with a best value of 0.13g/t, and the company is now targeting a basement gold target concealed by lake sediments.
  • Cash and investments totalled $13.5 million at the end of the June 2026 quarter.

Bulletin Resources Limited (ASX:BNR) released its quarterly report for the period ended 30 June 2026 on 31 July 2026. The report covers exploration at the Lake Rebecca Gold Project in Western Australia, including the Chifley prospect, field reconnaissance on the Pinjin project and planned geophysical and soil surveys.

This article describes the company, the sector context, the report and the factors that may influence its activities.

About Bulletin Resources

Bulletin Resources Limited is an ASX-listed gold exploration company based in Perth. Its Lake Rebecca Gold Project comprises 849 square kilometres of tenements in the southern Laverton Tectonic Zone, about 150 kilometres east-north-east of Kalgoorlie. The tenements lie south and east of Northern Star Resources' Carosue Dam operations, and Ramelius Resources' Rebecca and Roe gold projects.

The company has 293.61 million shares on issue, and a market capitalisation stated as $10.86 million at 3.7 cents. It also reviewed data over the Pinjin project, acquired from St Barbara in 2025. Bulletin does not report production revenue and appointed a Senior Geologist during the quarter to oversee exploration and project generation.

Sector backdrop

The Laverton Tectonic Zone is a major structural corridor in the Yilgarn Craton that hosts large gold deposits, and tenements near operating mines are explored for similar structural settings. Parts of the Lake Rebecca area are covered by lake sediments and transported cover, which can hide basement rocks and limit surface geochemistry.

Explorers use geophysics such as induced polarisation (IP) and gravity surveys to map buried structures and rock types, and ultrafine soil sampling to detect low-level geochemical signals through cover. Aircore drilling tests the cover and the top of the basement.

Anomalous gold in transported cover can indicate a source nearby, although it does not by itself indicate mineralisation in the basement.

June 2026 quarterly report released on 31 July 2026

Lake Rebecca exploration

The programs include 15 line-kilometres of dipole-dipole IP, 2,000 gravity stations and 700 ultrafine soil samples. The Board approved IP and ultrafine soil work over 10 priority gold targets, which began late in the quarter and remains in progress, and a first-pass gravity survey of 2,000 stations is proposed for inclusion.

At Chifley, aircore drilling in the March 2026 quarter comprised 11 holes for 797 metres. In the June quarter, detailed 1-metre assays through three gold-anomalous 3-metre composites returned a best value of 0.13g/t gold in transported saprolite. Two holes ended in fresh granite and the rest ended because of drilling difficulties in transported cover. Bulletin is now targeting a basement gold target concealed by lake sediments.

Pinjin and reconnaissance

Review of previous exploration data over Pinjin led to field reconnaissance over 18 gold targets. Reconnaissance mapping identified an 800 metre strike extent of patchy hematite lag with iron values above 59% Fe, and further mapping and sampling are proposed.

Corporate

Blake Collins was appointed Senior Geologist. Cash and investments totalled $13.5 million at the end of the quarter, which the company describes as a funding position relative to its current market capitalisation.

The company has 293.61 million shares and 97.87 million listed options on issue, with 7 million unlisted options. The Lake Rebecca tenements are south and east of Northern Star Resources' Carosue Dam operations, which the report describes as 4.0 million ounces, and Ramelius Resources' Rebecca and Roe projects of 1.4 and 1.8 million ounces. The report states that the Lake Rebecca project straddles geologically complex terranes within the Yilgarn Craton, with gold linked to major structures such as the Hootanui and Celia faults.

Core growth drivers and material operating risks

Core growth drivers

The items identified are the IP, gravity and ultrafine soil results, interpretation of the basement target at Chifley and follow-up mapping and sampling at Pinjin.

Material operating risks

The best gold assay reported is 0.13g/t in transported cover, which is low in grade, and drilling difficulties in cover prevented some holes from reaching basement. The hematite lag is a surface observation. Geophysical and soil surveys can identify targets but do not confirm mineralisation.

Results from the surveys are not yet reported, and the company will need funding for drilling after its cash and investments are used.

The company's market capitalisation of $10.86 million at 3.7 cents is below the cash and investments of $13.5 million reported at quarter-end, according to the figures in the report. The report describes the funding position relative to market capitalisation favourably, a view that is the company's own. Results from the IP, gravity and ultrafine soil programs are not yet reported, so the outcome of the current field program is still to come.
