Peregrine Gold Confirms Dry Blowing Works to Extract Gold From 3km Paleo Gravels
Key Takeaways
- Peregrine Gold recovered visible gold from both bulk sampling pits at the Peninsula Prospect, with Pit 1 yielding an estimated ~5.3g total and Pit 2 yielding ~7g — confirming dry blowing as an effective gold recovery technique in the Pilbara.
- The defined auriferous paleo gravel system now extends approximately 3.0km south of the Peninsula quartz vein, spanning the Peninsula Prospect, three SPL applications, and the Capricorn Prospect (M52/1097).
- Prior channel samples from 400m south of the bulk sampling pits returned assay-confirmed grades of 13.5 g/t Au and 1.8 g/t Au, providing laboratory-verified context for the field observations.
- 22 additional channel samples (26KPG 62–83) have been submitted to Intertek for assay — positive results could expand the total width of auriferous paleo gravels at the Capricorn Prospect to approximately 280m.
- Heritage approvals and Programme of Work lodgement are locked in for end of October 2026, with further bulk sampling and a Mining Development and Closure Plan to follow as the company advances toward small-scale mining operations.
Visible gold confirms dry blowing as viable extraction method at Peregrine’s Peninsula Prospect
Peregrine Gold (ASX: PGD) has recovered visible gold from two orientation bulk samples of paleo gravels adjacent to the Peninsula Prospect at its Newman Gold & Iron Ore Project. The programme confirmed the effectiveness of dry blowing techniques to recover gold from the paleo gravels. This builds on prior channel sampling at the site that returned up to 13.5 g/t Au (assay result, announced 10 July 2026).

What the bulk sampling programme delivered
Two pits were dug to test the paleo gravel system flanking the current creek drainage. Pit 1 was positioned approximately 110m south of the Peninsula auriferous quartz vein, whilst Pit 2 was located 20m south of the vein. Between 500-700kg of paleo gravel material was extracted from each pit, run through a dry blower on site, and the concentrate then panned.
Critical qualifier: The gold recoveries reported below are qualitative field observations only. They are not assay results, grades, or reportable figures. Peregrine does not intend to submit the recovered specimens for laboratory assay, and no inference on grade, continuity, or economic potential can be drawn from these visual observations.
| Pit | Location relative to vein | Material processed | Visible gold recovered (field estimate only) | Depth interval |
|---|---|---|---|---|
| Pit 1 | ~110m south | 500-700kg | 48g ironstone-quartz-gold specimen (~10% gold) + ~0.5g smaller pieces ≈ ~5.3g estimated total | 0.00-0.90m gravels |
| Pit 2 | ~20m south | 500-700kg | ~7g as collection of smaller pieces | 0.00-0.55m gravels |
Footnote: Visual gold recoveries are qualitative field observations only and do not represent reportable grades. No inference regarding grade, continuity, or economic potential should be drawn from these estimates.
Both pits returned visible gold in the pan, confirming the presence of auriferous material and the effectiveness of dry blowing as a recovery technique.
Gold-rich gravels extend across the prospect
The bulk sampling results connect to prior assay-confirmed results located approximately 400m south of Pit 1 and Pit 2. Channel samples 26KPG 2 and 26KPG 4 from that area returned 13.5 g/t Au and 1.8 g/t Au respectively (announced 10 July 2026). These are laboratory assay results, not field observations.
Sampling across Mining Lease Application M52/1097 (known as the Capricorn Prospect) reported gold-anomalous paleo gravels over a strike length of approximately 2.6km (announced 4 August 2026). Auriferous paleo gravels are now defined continuing south for approximately 3.0km from the Peninsula auriferous quartz vein.
The defined paleo gravel system now spans:
- Peninsula Prospect (E52/3850)
- SPL applications P52/1703-S and P52/1705-S
- Capricorn Prospect / Mining Lease Application M52/1097
Understanding paleo gravels and dry blowing
Paleo gravels are ancient river gravel deposits that can concentrate gold eroded from primary mineralised sources upstream. Over geological time, these gravels become buried and preserved, creating a secondary gold target that can be shallow, accessible, and potentially easier to mine than hard-rock deposits.
Dry blowing is a low-water gold recovery technique that uses air to separate heavier gold particles from lighter gravel and sediment. It is particularly well suited to arid regions like the Pilbara, where water availability is limited and traditional wet processing methods are impractical or costly.
For investors, confirming dry blowing as an effective extraction method supports the potential for small-scale mining operations that do not require water-intensive processing infrastructure. This lowers capital and operational costs, and accelerates the path to production if the resource proves economically viable.
Assays pending and the 280m expansion potential
Peregrine collected a further 22 channel samples (26KPG 62 to 83) across the older inferred paleo gravel unit (Tpg) at the Capricorn Prospect. These samples have been submitted to Intertek for geochemical analysis, with pan samples yet to be processed.
The Tpg unit has already returned anomalous gold — sample 26KPG 61 recorded 0.45 g/t Au (assay result, announced 4 August 2026). If the additional samples confirm the Tpg unit is auriferous, the collective width of auriferous paleo gravels across the Capricorn Prospect could increase to a maximum width of approximately 280m, significantly expanding the scale of the system under evaluation.
Investment significance: The pending assays represent a near-term catalyst. Positive results would materially expand the defined gold footprint and strengthen the case for economic extraction across a wider area. The combination of strike length (3.0km) and potential width (280m) changes the scale of the opportunity.

What comes next for Peregrine
Peregrine’s forward plan is subject to Programme of Work and Heritage Approval, locked in for end of October 2026. The company intends to:
- Analyse and interpret assays over the older inferred paleo gravel unit (Tpg)
- Undertake further bulk sampling to assess gold grades within the inferred paleo gravel unit
- Undertake additional trial dry processing (dry blowing) to assess suitability
- Complete a Mining Development and Closure Plan (MDCP) to support small-scale mining operations
George Merhi, Technical Director
“The orientation bulk sampling programme was very effective in that it has confirmed that the paleo gravels are highly auriferous and that dry blowing techniques can be an effective method of extracting gold.”
“Auriferous paleo gravels are now defined immediately south of the auriferous quartz vein at the Peninsula Prospect and continue south for approximately 3.0 kilometres. This successful orientation bulk sampling work has provided the confidence for Peregrine to advance the paleo gravel project south of the three SPLs to include bulk sampling, subject to lodging a PoW and completing heritage work, which is locked in for the end of October 2026. The inferred older paleo gravel unit (Tpg) could, if confirmed auriferous, add significantly to the gold footprint at the Capricorn Prospect.”
Heritage work is scheduled for completion end of October 2026, with pending assays and further bulk sampling as the next catalysts. The programme is advancing systematically toward small-scale mining operations at the Newman Gold & Iron Ore Project.
