Ada Ann
Gold ProJect
Maiden JORC compliant inferred Mineral Resource at Ada Ann using a 0.5g/t lower cutoff.
*Source: ASX Release - Maiden Ada Ann Mineral Resource Estimate - Updated, 18 August 2025
The Ada Ann prospect is our highest priority target due to its historic drilling results and recent high grade surface samples. The prospect has significant, shallow, historic drilling intersections including:
7m @ 5g/t Au (from 4m)
6m @ 6.5g/t Au (from 16m)
16m @ 2.6g/t Au (from 24m)
Forrestania is testing extensions to known mineralisation and an area around historic drill spoils that returned strong results, including 49g/t Au.
The Ada Ann prospect forms the cornerstone of the Bonnie Vale project, with a maiden JORC-compliant resource of 12,419oz Au, reported on 18 August 2025.
Mineralisation remains open along strike and at depth, highlighting strong potential for resource growth through targeted drilling.
Forrestania Resource’s Bonnie Vale Project (E15/1632 & E15/1534) is in close proximity to major gold mines and deposits.Map includes simplified geological interpretation with WA Government magnetics. ASX: EVN Mungari lies ~5km to the east of the Bonnie Vale Project area. (ASX: EVN Mungari mine life taken from ASX: EVN Mungari mine life extended to 15 years - 5th June 2023; Mungari Mineral resource estimate figure of 5.9Moz & Rayjax Ore Reserve taken from ASX: EVN Mungari Mineral Resource & Ore Statement as at 31st December 2023 - 14th February 2024; ASX: FML Bonnie Vale mineral resource update, 26th September 2023.)
Lies within the Kunanalling Shear Zone, a significant, geological structure hosting several gold discoveries.
Two shallow historic pits at the prospect reportedly produced 150t @ 7g/t Au. The deepest historic hole is at 86m with mineralisation untested at depth.
Sample Analysis
AARC0022-AARC0035: All samples (both 4m composites and 1m samples) were submitted for Au analysis using Au-AA25 methodology (fire assay) which uses a fire assay fusion FA-FUS03, with an AAS finish.
AARC0001-AARC0021: Samples were submitted for Au analysis using AuMe-TL43 (aqua regia); Aqua regia digestion of 25g sample, followed by trace Au and multi-element analyses by ICP-MS and ICP-AES. 1m samples were submitted for Au analysis using Au-AA25 methodology (fire assay) which uses a fire assay fusion FA-FUS03, with an AAS finish.
Historic and recent downhole max results at the Ada Ann prospect with significant results indicated. Drilling results are down hole width and not true width.

Exploration Potential
Large project area (˜90km²) is host to multiple historic workings & prospects, including Ada Ann and the Christmas Gift mine
Additional drilling imminent at Ada Ann prospect, targeting extensions of maiden resource and testing parallel structures to build scale
6 Aug 2025: Expansion of footprint directly south of Ada Ann, within a geologically rich corridor
12 Aug 2025: Additional binding agreement to acquire gold rights on prospecting license and mining lease application. New tenements located directly north of Ada Ann
Strategic Value
Close proximity to major operating mines and processing infrastructure, incl EVN Mungari (5km east), EVN Rayjax (4km south) and EVN Cutters Ridge (1km north)
Strengthens Forrestania’s growth pipeline and potential for rapid resource expansion

Bonnie Vale North
Gold Prospect
The Bonnie Vale North Prospect has highly anomalous zones of strong Au geochem. The Kunanalling Shear Zone strikes through the entirety of the tenement and is coincident with anomalous geochem.
Historic RAB drilling (11m @ 0.33g/at Au) followed up by RC drilling in 2022 confirmed open mineralisation at depth: 3m @ 2g/t Au (from 77m).
Subtle magnetic structure appears to be a similar structure to what hosts ASX:EVN Cutter’s Ridge (1.2km north).
Bonnie Vale REgional
Gold Prospects
The Bonnie Vale tenement includes a number of prospective workings, previous exploration results and geophysical anomalies that have not been properly explored, and will be the target of ongoing regional fieldwork and drilling programmes.
Historic mining results of up to 40.5g/t Au at the Christmas Gift mining centre (not part of the FRS tenement).
Significantly anomalous Geochem including:
Rock chip – 2.7g/t Au
Soil sample – 354ppb Au
Significant historic drilling results, including:
4m @ 4g/t Au (including
1m @ 14.3g/t Au)
