Voltaic Strategic Resources Returns to El Dinero With Encouraging Copper Observations
Key Takeaways
- Field reconnaissance at El Dinero returned average indicative pXRF copper readings of up to 8.31% Cu across four visibly mineralised samples, with malachite-rich gossanous material identified across an approximately 100m area.
- These pXRF results build directly on June 2024 laboratory rock-chip assays that confirmed copper-gold mineralisation at El Dinero, including up to 2.57% Cu and 2.25 g/t Au — this is not a first-pass observation.
- Laboratory analysis of all 40 samples collected during the current field program is now underway, with results expected to determine the basis for systematic follow-up mapping and potential maiden drilling.
- Voltaic has outlined a four-step pathway from current lab analysis through heritage and permitting requirements toward defining targets for potential maiden drilling at El Dinero.
- El Dinero sits within the Murchison Goldfields alongside the NOA Corridor and Ruby Gem prospects, giving Voltaic multiple active exploration fronts within the same project area.
Malachite-rich copper target emerges at El Dinero
Voltaic Strategic Resources has returned to field exploration at its El Dinero prospect within the Meekatharra Project in Western Australia, identifying malachite-rich gossanous material across multiple locations within an approximately 100m area. This is not a new copper occurrence — it builds directly on laboratory rock-chip assays from June 2024 that confirmed copper-gold mineralisation at the prospect, including up to 2.57% Cu and 2.25 g/t Au.
Four copper-mineralised rock samples were selected for portable XRF (pXRF) screening during the field reconnaissance, returning average indicative copper readings ranging from 1.88% to 8.31% Cu. Laboratory analysis of all 40 samples collected during the program is now underway.
Daniel Raihani, Chairman
“These are encouraging early observations from our return to field exploration at Meekatharra. Importantly, El Dinero is not a new copper occurrence, with previous laboratory rock-chip assays having confirmed copper-gold mineralisation at the prospect, including up to 2.57% copper and 2.25 g/t gold. The identification of further malachite-rich material across multiple locations provides a clear basis for systematic follow-up work. Our immediate priority is to complete laboratory analysis of the samples collected and return to the field to better define the extent of the mineralised system and develop targets for potential drilling.”

pXRF results in focus — what the numbers show
Reading the preliminary data
The four copper-mineralised samples were each screened using two separate portable XRF instruments, with three readings taken per sample per instrument. The average indicative pXRF copper readings across the four samples are presented below.
| Sample ID | Average Indicative pXRF Cu Reading | Notes |
|---|---|---|
| GS000546 | 1.88% | |
| GS000547 | 4.91% | |
| GS000548 | 5.30% | |
| GS000549 | 8.31% |
These figures are preliminary and semi-quantitative. The pXRF readings were taken specifically from visibly mineralised portions of each sample displaying malachite and/or interpreted chalcopyrite — they are not representative of the average copper grade of the whole rock sample or of any broader mineralised zone. Laboratory analysis is required to confirm representative grades.
Understanding copper-gold exploration — why malachite matters
For investors less familiar with early-stage exploration, it helps to understand what these observations actually mean and where they sit in the broader exploration workflow.
- Malachite is a bright green copper carbonate mineral. Its presence at surface is a visible indicator of underlying copper mineralisation, making it a meaningful target for field geologists.
- Gossanous material forms when sulphide minerals weather at the surface over geological time. This weathered cap often signals that primary sulphide mineralisation exists at depth.
- pXRF is a rapid, handheld field-screening tool. It provides a quick read on elemental composition in the field but is semi-quantitative by nature. Laboratory assay results are required before any grade can be considered confirmed or representative.
- The typical early-stage progression runs: surface observation → pXRF screening → laboratory assay → systematic geological mapping → potential drilling.
The significance of these observations is not that they define a resource. They do not. What they provide is a spatial and geological basis for designing a systematic follow-up program at a prospect that has already returned confirmed copper-gold values from laboratory analysis. That distinction matters when assessing where El Dinero sits in the exploration timeline.

What comes next for El Dinero and the Meekatharra Project
The company has outlined four immediate next steps for El Dinero:
- Laboratory analysis of the 40 rock samples collected during the current field program (36 targeting gold mineralisation and 4 copper-mineralised samples) is currently underway.
- Voltaic plans to return to El Dinero to undertake systematic geological mapping and surface sampling aimed at defining the extent, orientation, and continuity of the observed copper-gold mineralisation.
- The company will progress relevant heritage, access, and permitting requirements to facilitate potential future drilling.
- Results from the laboratory program and follow-up field work will be used to refine and prioritise targets for potential maiden drilling at El Dinero.
El Dinero is one of several priority areas within Voltaic’s Meekatharra Project, which sits within the Murchison Goldfields — an established gold and base metals region in Western Australia. The broader portfolio also includes the NOA Corridor, a prospective geological trend extending north from the Burnakura gold mining area, and Ruby Gem, which contains historical workings that provide an immediate focus for geological assessment.
The NOA Corridor gold discovery at Meekatharra represents another active front within Voltaic’s broader project portfolio, with high-grade surface anomalies identified along the prospective trend extending north from the Burnakura gold mining area.
Systematic follow-up work is the immediate priority at El Dinero. The confirmed copper-gold history at the prospect, combined with the latest field observations, underpins the rationale for advancing this target toward potential maiden drilling.
