Highlights
- Drilling activities advance on the Heli-EM targets at the Dianne Cu project.
- As a part of the planned drilling program, two holes have been completed to date.
- Recently received soil sampling results have indicated significant copper and gold anomalism at the EM drill targets zones.
- The company has kicked off a high-resolution helicopter gravity survey over Larramore Belt.
Revolver Resources Holdings Limited (ASX: RRR) has shared an update on the ongoing exploration activities along the Larramore Volcanic Belt at its Dianne Copper project, Northern Queensland.
In July, the company started preliminary exploration drilling of three targets – C16, C5 and C6. To date, two diamond holes have been completed, as part of the nine-hole drilling campaign. Initial assay results are expected from late September. The third diamond hole is also underway.
Meanwhile, the company has also commenced a high-resolution helicopter gravity survey over Larramore Belt.
The company also reported new soil sampling results that indicated extensive copper and gold anomalism across key EM drill target zones within the Larramore trend.

Heli-EM targets identified
As discussed above, a helicopter electromagnetic and magnetic data survey was concluded in 2022 over a 37km2 prospective area within the western part of the Dianne project.
RRR informed that 16 high-priority bedrock anomaly targets were deemed solid targets for follow-up drilling and identified to be consistent with an accumulation of sulphides.
Soil sampling program defines significant anomaly
A detailed soil geochemistry grid was undertaken by the company along the gossanous trend to identify the areas of mineralisation.
RRR had collected around 325 soil samples on the east-west oriented lines as a part of the field work. The sampling results demonstrated an extensive, coherent and linear geochemistry anomaly. This anomaly returned gold and copper with associated elevated Te, Ni, Sb, Ag, Mn, Co and Fe.
The anomalism strength, in combination with anomalous zones’ coherence and size and the identified Heli-EM anomalies, indicated the prospectivity around the C5, C6 and C16 targets.
Drilling progresses at C16, C5 and C6 targets
As previously mentioned, the drilling campaign began in July and to date, two holes have been completed at the C16 target, and one hole is underway. The focus of the two drillholes - 23LMDD003 and 23LMDD004 was to strike the stockwork zone below the geochemical anomalism and observed outcrop and above the deeper EM target.
Data Source: Company update
Revolver highlighted that the presence of any grade of mineralisation is unknown, and a laboratory chemical assay is necessary to ascertain the grade of mineralisation. From late September, the company expects to receive multi-element assays.
