Ada Ann Drilling Results Confirm High-Grade Gold of Up to 26g/t Au
Forrestania Resources (ASX: FRS) has confirmed significant high-grade gold mineralisation at its Ada Ann prospect within the Bonnie Vale Project near Coolgardie in Western Australia's prolific Eastern Goldfields.
1m Drilling Results Reveal Exceptional Gold Grades
The one-meter assay results from Forrestania Resources Ada Ann gold drilling results have confirmed impressive high-grade gold mineralisation at Ada Ann, with standout intercepts including:
- 7m @ 4.3g/t Au (from 72m), including 1m @ 25.6g/t Au in hole AARC0029
- 3m @ 7.8g/t Au (from 74m), including 1m @ 22.2g/t Au in hole AARC0028
- 3m @ 5.9g/t Au (from 82m), including 1m @ 16g/t Au in hole AARC0024
These results build on previous significant intercepts from phase 1 drilling, which included 2m @ 10.7g/t Au (including 1m @ 21g/t Au) in hole AARC0002, further demonstrating the high-grade gold intercepts at Ada Ann.
Expanding Mineralisation Footprint
The recent Forrestania Resources Ada Ann gold drilling results have successfully extended the known mineralisation:
- Approximately 60 meters south of previously known mineralisation
- Approximately 30 meters north of previously known mineralisation
- Total strike length of gold mineralisation increased to approximately 310 meters
Importantly, the mineralisation remains open at depth and along strike in both directions, suggesting significant potential for further resource expansion, similar to recent drilling success at Mt Palmer.
"These 1m results from Ada Ann are highly significant, with grades up to 26g/t Au, underlining the high-grade potential of the system," said Forrestania Resources' Chairman John Hannaford. "Pleasingly, we are seeing some thickening of the mineralised zones at depth. The drill programme extended the known mineralised zones to the north and south and the prospect continues to remain open in all directions."
Strategic Location in the Eastern Goldfields
The Bonnie Vale Project is strategically positioned in one of Australia's most productive gold regions, in close proximity to established gold operations. The project area is just 5km from Evolution Mining's Mungari operation, which has a 15-year mine life and significant mineral resource estimate of 5.9Moz gold.

| Flying Fox nickel mine | Operating mine in proximity |
| Spotted Quoll nickel mine | Operating mine in proximity |
Understanding Gold Systems in Shear Zones
The Ada Ann prospect appears to be composed of a gently east-dipping (25-30°) shear-hosted gold system with contact mineralisation on the footwall and hanging wall basalts and schists.
What is a Shear-Hosted Gold System?
Shear-hosted gold systems form when gold-bearing fluids move through zones of rock deformation called shear zones. These zones act as conduits for mineralised fluids that deposit gold as conditions change. At Ada Ann, this has resulted in consistent zones of high-grade gold mineralisation at the contact between different rock types.
The low dip angle of the mineralised structure is particularly significant for potential mining scenarios, as the true width of the mineralisation is estimated to be approximately 98% of the reported down-hole widths. This means the significant high-grade intercepts reported represent almost exactly the actual thickness of the gold-bearing zones.
Future Exploration Plans
Following these encouraging Forrestania Resources Ada Ann gold drilling results, the company is planning to:
- Focus immediate attention on drilling at the Lady Lila prospect
- Continue analysis and planning for further drilling at Ada Ann
- Develop a comprehensive exploration program for the broader Bonnie Vale project area
The company has already identified further exploration potential approximately 225 meters south of the current drilling area, where historic shallow workings and anomalous gold values (including 4m @ 0.3g/t Au from surface) have never been adequately followed up.
Why Investors Should Take Note
Forrestania Resources' Ada Ann prospect represents a compelling investment opportunity for several key reasons:
-
High-grade gold confirmed: Multiple intercepts above 20g/t Au demonstrate the potential for economically significant mineralisation.
-
Growing mineralisation footprint: The strike length has expanded to 310m and remains open in all directions, suggesting significant resource growth potential.
-
Favourable mining geometry: The relatively flat-lying nature of the mineralisation (25-30° dip) means the reported intercepts are close to true width, potentially enhancing mining economics.
-
Strategic location: Proximity to Evolution Mining's Mungari operation (5.9Moz resource) highlights the region's prospectivity for major gold discoveries.
-
Multiple near-term catalysts: With drilling to commence at Lady Lila and further work planned at Ada Ann, investors can expect a steady flow of news in the coming months.
The consistent high-grade results from both the first and second phases of drilling, combined with the expansion of the mineralised footprint, position Ada Ann as an increasingly significant gold prospect in Western Australia's Eastern Goldfields. Furthermore, the potential revenue from gold stockpiles could be significant for companies like Forrestania Resources that continue to identify high-grade gold at their projects.
