Flynn Gold Sends 3.7t Bulk Sample to Henty for Gold Processing Testwork
Key Takeaways
- Flynn Gold has delivered a 3.7-tonne Golden Ridge bulk sample to the Henty Gold Mine, with processing testwork results still pending.
- Earlier sighter work averaged 10.54g/t Au with 94.9% gold extraction, though the test conditions were more intensive than typical CIP or CIL processing.
- The Ore Purchase Agreement with Kaiser Reef's Henty Gold, signed 6 August 2026, is non-binding and sets out terms rather than committing either side to a sale.
- If the testwork succeeds, Flynn will seek government approval to supply larger quantities for trial processing through the Henty plant.
- Flynn holds A$1.12M cash at 30 June 2026 and nil debt against an A$8.5M market cap, with four of 21 approved Brilliant drillholes completed and assays pending.
Flynn Gold sends 3.7-tonne Golden Ridge bulk sample to Henty Gold Mine for processing testwork
Flynn Gold (ASX: FG1) has delivered a 3.7-tonne bulk sample from its 100%-owned Golden Ridge Gold Project in north-east Tasmania to the Henty Gold Mine for processing testwork. Results are pending.
The delivery follows the non-binding Ore Purchase Agreement signed on 6 August 2026 with Henty Gold Pty Ltd, a wholly-owned subsidiary of Kaiser Reef Limited (ASX: KAU). Because the agreement is non-binding, it sets out terms rather than committing either side to a sale.
The company says the Ore Purchase Agreement opens a potential processing pathway, which could reduce upfront capital requirements.
Neil Marston, Managing Director and CEO
“This is another significant step for Flynn Gold on our pathway towards future gold production from Golden Ridge.”
On capital, Flynn lists a market capitalisation of A$8.5M, cash of A$1.12M at 30 June 2026 and nil debt.

What the sighter testwork showed
A “sighter” program is an early, small-scale test designed to give a first indication of how material behaves. The bulk sample came from quartz-sulphide veins exposed by trenching, and Flynn excavated it in May 2025.
2025 results
Six representative grab samples were collected and split into 12 samples, which averaged 10.54g/t Au. Cyanide bottle roll testing (LeachWELL) returned average gold extraction of 94.9%.
Key facts from the sighter program:
- Bulk sample weight: 3.7 tonnes
- Average grade: 10.54g/t Au across 12 samples
- Average gold extraction: 94.9%
- Grind size: 85% passing 75 micron
The company notes that LeachWELL test conditions are more intensive than those typically used in conventional Carbon-in-Pulp (CIP) or Carbon-in-Leach (CIL) processing. Further testwork is therefore required to establish recoveries under potential commercial processing conditions.
Why does plant-based testwork matter?
A laboratory leach test soaks crushed rock in a cyanide solution under aggressive conditions to see how much gold dissolves. Kinetic leach testing measures how gold dissolves over time, and the Henty team will use it alongside other tests to simulate its processing plant conditions.
That distinction matters to you as an investor. Any ore sale pathway depends on proven recoveries, so the Henty testwork is the key de-risking step.
The pathway, as Marston described it, runs in this order:
- Henty testwork on the bulk sample.
- Should the testwork prove successful, Flynn will seek government approval to provide larger quantities of similar material for trial processing through the Henty gold plant.
- Future ore sales to the Henty Gold Mine, with the non-binding Ore Purchase Agreement setting out the key terms.
What are the next steps, and how is drilling at Brilliant going?
Approximately 100kg of the bulk sample material will be set aside for gravity separation and crushing testwork.
Resource drilling at the Brilliant prospect is ongoing, with four of 21 approved drillholes completed to date. Assays are pending. Investors can ask questions through the Flynn Gold Investor Hub at https://flynngold.com.au/link/PR1zXr.

How big is Golden Ridge?
Exploration has identified extensive intrusion-related gold system (IRGS) mineralisation extending over a 9km-long zone along the southern contact margin of the Golden Ridge Granodiorite.
In November 2024, the company announced a JORC-compliant Exploration Target of 449,000 to 520,000oz (3.5 to 5.4Mt at 3.0 to 4.0g/t Au). An Exploration Target is a conceptual estimate of the potential size and grade of a deposit, not a Mineral Resource.
The size and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource, and it is uncertain if further exploration will result in one. The target also has not yet been updated to include drilling completed in 2025 or 2026.
| Prospect | Tonnes (Mt) | Grade (g/t Au) | Contained Au (oz) |
|---|---|---|---|
| Trafalgar | **1.6 – 2.2** | **4.5 – 6.0** | **303,000 – 322,000** |
| Brilliant | **1.4 – 2.2** | **1.6 – 1.9** | **82,000 – 115,000** |
| Link Zone | **0.6 – 0.9** | **2.8 – 3.5** | **64,000 – 83,000** |
| Total | **3.5 – 5.4** | **3.0 – 4.0** | **449,000 – 520,000** |
Previous drilling at Trafalgar returned multiple intersections above 100g/t Au. One example is hole TFDD005, which returned 12.3m at 16.8g/t Au, including 0.7m at 152.5g/t.
Flynn has focused on north-east Tasmania because of similarities with the geology and gold mineralisation styles of the Victorian Goldfields. The company also describes Tasmania as an exploration and mining-friendly jurisdiction.
