Resources & Energy Group Hits 15.84g/t Gold at Maranoa Ahead of JV Mining
Key Takeaways
- REZ's July 2026 RC grade control program at Maranoa returned headline intercepts of 2m @ 15.84g/t Au and 4m @ 10.38g/t Au, confirming high-grade mineralisation directly beneath and along strike from the historic workings.
- The RC rig has already been remobilised to site with 1,200–1,500m of follow-up grade control drilling planned south along the line of workings, before all assays from the initial program have been returned.
- Under the Maranoa tribute mining JV with Rembrandt Mining Pty Ltd, REZ retains 100% tenement ownership while Rembrandt funds the mining campaign — REZ bears zero mining capital expenditure under this structure.
- The existing Maranoa JORC 2012 Inferred Resource stands at 46,000 tonnes at 5.7g/t for 8,000oz; the current drilling program is designed for mine planning and ore definition, not a resource estimate revision.
- Maranoa sits within the broader East Menzies Gold Project, a 100km²+ package hosting over 112,000oz Au in defined resources across four deposits, with structural mapping underway to generate additional drill targets across the belt.
High-grade gold confirmed beneath Maranoa’s historic workings
Resources & Energy Group Limited (ASX: REZ) has returned high-grade gold intercepts from its July 2026 RC grade control drilling program at the Maranoa Gold Project, part of the East Menzies Gold Project located approximately 130km north of Kalgoorlie, Western Australia. The results confirm the continuity of mineralisation directly beneath and along strike from the historic Maranoa workings, providing the data foundation needed to advance mine planning under the Maranoa tribute mining and production joint venture with Rembrandt Mining Pty Ltd.
The program comprised 9 RC holes for a total of 614m drilled at a nominal 10x20m spacing, with 7 angled holes drilled beneath the workings and 2 vertical holes testing down-plunge positions. Assays remain pending for 2 holes (26MRC041 and 26MRC043), and 3 holes intersected historic stopes.
Headline intercepts from the program include:
- 2m @ 15.84g/t Au from 57m (26MRC042)
- 4m @ 10.38g/t Au from 81m (26MRC051)
- 4m @ 2.76g/t Au from 72m (26MRC051)
- 2m @ 3.25g/t Au from 73m (26MRC050)
- 1m @ 2.34g/t Au from 56m (26MRC046)
The RC rig has already been remobilised to site, with approximately 1,200–1,500m of follow-up grade control drilling planned to extend the pattern south along the line of workings. Holes in the follow-up program will be drilled at an angle beneath the workings.

What grade control drilling means for investors
Most retail investors are familiar with exploration drilling — the process of finding a gold deposit and defining how large and how rich it might be. Grade control drilling is a different, more advanced step. It happens just before mining begins, and its purpose is to map the ore boundaries and confirm gold grades with enough precision to plan extraction safely and profitably.
At 10x20m collar spacing, the Maranoa program is operating at mine-planning resolution. This is not speculative work. The results feed directly into ore scheduling and cut-off grade decisions, telling the mining team exactly where the high-grade material sits and how to sequence extraction.
The joint venture structure matters here. Under the Maranoa tribute mining and production joint venture, REZ retains 100% ownership of the tenement while Rembrandt Mining Pty Ltd funds the mining campaign under a sliding-scale profit share. REZ bears no mining capital expenditure under this arrangement. That means each additional batch of grade control assays that confirms high-grade continuity narrows the risk window between resource definition and active production, without REZ deploying its own capital to get there.
Maranoa’s resource foundation and the broader EMGP picture
Existing mineral resource
The Maranoa Gold Deposit holds an existing JORC 2012 Inferred Mineral Resource of 46,000 tonnes at 5.7g/t gold for 8,000 ounces, reported at a 1.0g/t gold cut-off grade. This estimate was reported to ASX on 11 June 2020 and has not been revised since. Importantly, the grade control drilling reported in this announcement is designed to inform mine planning and ore definition — it is not an update to the Mineral Resource estimate. The company has stated it will advise the market if and when the estimate is revised.
| Deposit | Classification | Tonnes | Grade (g/t Au) | Ounces | Cut-off (g/t Au) |
|---|---|---|---|---|---|
| Maranoa | Inferred (JORC 2012) | 46,000 | 5.7 | 8,000oz | 1.0 |
Reported in accordance with the JORC Code 2012. Refer to ASX announcement dated 11 June 2020.
Maranoa sits within the broader East Menzies Gold Project, a contiguous package of mining, exploration, and prospecting licences exceeding 100km² within the Wiluna-Norseman Greenstone Belt. The EMGP portfolio hosts several high-grade lode gold systems, with the following Mineral Resource Estimates (MREs) disclosed in the project map (Figure 3 of the ASX announcement):
- Goodenough: 61,200oz Au (Indicated & Inferred, JORC 2012)
- Gigante Grande: 40,700oz Au MRE (Indicated & Inferred, JORC 2012), plus an Exploration Target of 160,000–500,000oz Au (JORC 2012)
- Granny Venn: 3,000oz Au (Indicated & Inferred, JORC 2012)
- Maranoa: 8,000oz Au (Inferred, JORC 2012)
Goodenough Prospect drilling has been advancing in parallel, with REZ confirming gold extensions at the deposit that hosts the largest MRE across the EMGP portfolio at 61,200oz Au.
Target generation underway across the broader belt
Beyond the current grade control focus area, the Maranoa Goldfield hosts multiple lines of historic high-grade gold workings that remain sparsely drill-tested. Structural geological mapping has commenced along the Maranoa belt, concentrating on these historic workings to generate further drill targets. This mapping is ongoing.

MD’s verdict and what comes next
J. Daniel Moore, Managing Director & CEO, Resources & Energy Group Limited (ASX: REZ)
“These high-grade intercepts from grade control drilling at Maranoa are an excellent early result, confirming the continuity of mineralisation beneath and along strike from the historic workings. Grades of this order, particularly the 2m @15.84 g/t and 4m @10.38 g/t intersections, validate our model of the Maranoa lodes and support the next stage of grade control drilling. With the RC rig now remobilised to site, we are moving quickly to follow up these results with an extended program to the south along the line of workings. Alongside this, our geological mapping team continues to define further drill targets across the broader Maranoa belt, where multiple lines of historic high-grade workings remain underexplored…”
The pace of follow-up is notable. The RC rig was remobilised before all assay results had been returned, signalling operational momentum in advancing the grade control program. For investors, each additional round of grade control assays brings the JV mining campaign closer to execution.
The near-term pipeline includes:
- RC rig remobilised to site — approximately 1,200–1,500m of further grade control drilling planned, extending the pattern south along the line of workings, with holes drilled at an angle beneath the workings
- Assay results pending for 26MRC041 and 26MRC043 — a market update will follow on receipt
- Structural geological mapping ongoing across the broader Maranoa belt to generate new drill targets
- JV mine planning progresses as grade control data accumulates
The mineralisation at Maranoa is hosted in quartz veins ranging from 0.5–2.5m in thickness, with the angled holes reporting approximate true widths and the two vertical holes (26MRC050 and 26MRC051) reporting apparent widths of approximately twice the true width. All assays were conducted by SGS in Perth using 50g charge fire assay, with certified reference materials inserted into the sample stream across altered and quartz-veined intervals.
