Investigator Resources hold the 583km2 Peterlumbo tenement within the southern Gawler Range Volcanics (GRV) of South Australia.

Beyond Paris: Uncovering a 15km Silver Corridor

The Paris Silver Corridor consists to The Peterlumbo tenenment (EL6347 – 100% IVR) and the Black Hill tenement (EL6475), held under a Joint Venture with Alliance Resources Limited since 2025.

This broad mineralised corridor hosts a number of confirmed silver prospects which are being explored to grow the silver endowment around Paris.

The southern Gawler Range Volcanics is prospective for low-intermediate sulfidation epithermal systems (Paris Ag – Pb deposit located within the Peterlumbo holding), Paleoproterozoic replacement style mineralisation, IOCG systems, skarn mineralisation and porphyry Cu – Au mineralisation.

Recent Exploration highlights extend Paris Silver Corridor over 15kms and include:

1m @ 71g/t Ag & 0.6% Pb from 38m (PLAC161)

42m @ 0.28% Pb and 48m @ 0.56% Zn from 51m (incl 3m @ 1%

3m @ 86g/t Ag from 90m, including 1m @ 218g/t Ag from 91m

Results continue to indicate favorable geology at new prospects and evidence of a silver/lead/zinc mineralised system.

The Athena Prospect (formerly known as Sunday Iron) is a highly prospective silver exploration target located in South Australia, just 11 kilometres southeast of Investigator’s flagship Paris Silver Project. Athena sits within a broader mineralised corridor that also hosts the Perseus and Manto silver prospects — a belt that Investigator believes is significantly underexplored for silver.

Athena lies within the Black Hill tenement (EL6475), held under a Joint Venture with Alliance Resources Limited, and is part of the same mineralised system that underpins the success of the Paris Silver Project. While historical exploration at Athena focused exclusively on iron ore, the geology shares key similarities with Paris, including altered calc-silicate host rocks and proximity to major structural features.

Previous drilling campaigns at Athena (then Sunday Iron) were undertaken between 2012–2013 by Trafford Resources, targeting iron-rich units. These holes were terminated as soon as the iron units were intersected — with no testing of the surrounding geology for precious metals.

Following the discovery of Paris, selected historical drill samples were re-assayed for silver, returning highly encouraging results, including:

5m @ 493 g/t Ag from 71m, including 1m @ 950 g/t Ag

Critically, many drillholes ended within silver mineralisation, and key intervals were never sampled or assayed. These gaps present an immediate opportunity for Investigator to extend known mineralisation and discover new zones with systematic follow-up work.

Investigator’s exploration strategy within the Paris Silver Corridor is grounded in the same rigorous, geology-first methodology that guided the Paris discovery. The team is currently preparing to undertake:

Field mapping, followed by targeted geophysical and geochemical surveys to refine structural interpretation
Drill planning to test extensions of known mineralisation and identify new zones

Athena represents an opportunity to uncover significant silver mineralisation in a known mineralised corridor with minimal modern exploration. With verified high-grade silver intersections, favourable geology, and close proximity to existing resources, Athena is a natural extension of Investigator’s regional growth strategy.

Investigator Resources is committed to unlocking the silver potential of the southern Gawler Craton through disciplined, technically driven exploration.
