Yeoval Goodrich Project Overview
Completion of Stage 1 to achieve a 51% Project Interest
The Company signed an Earn-in and Joint Venture Agreement (“Agreement”) with ASX listed, Godolphin Resources Ltd (“Godolphin”) on 4 June 2025. Under the terms of the Agreement, GPS had the right to earn a 51% interest by incurring A$1,000,000 in Exploration Expenditure. Additionally, the Company was required to complete a minimum of 500 metres of reverse circulation and/or diamond drilling. GPS has provided Godolphin with a Satisfaction Notice that the Stage 1 Earn-in commitments have been met.
Furthermore, the Company has provided Notice to Godolphin that it elects to progress to Stage 2 of the Agreement. Under the terms of Stage 2, GPS must incur a further A$1,000,000 in Exploration Expenditure over the next 12 months and complete a minimum of 500 metres of reverse circulation and/or diamond drilling to increase its interest to 70%. The Company completed a private placement in the amount of $4.18 million in February 2026 to ensure it was funded to progress the project through the next phase. The alternative path to Stage 2 is if Godolphin informs the Company within 20 business days from the date the Notice was given that it prefers to form a 51/49% Joint Venture (in favour of GPS) and will then be responsible for 49% of the future expenditure.
Summary of exploration activities during Stage 1
The recent air-core program covered 2,065 metres of shallow air core drilling around the former Goodrich mine and Mt Rose. This has successfully advanced geological understanding at the Goodrich and Mt Rose targets.
Importantly, the historical Goodrich mine and the newly recognized pencil porphyry at Mt Rose appear to represent focal points within a widespread hydrothermal system and strengthens the case that a previously unrecognized porphyry copper-gold system could be present at Yeoval Goodrich.
A local contractor commenced diamond drilling (Figure 1) at Goodrich in May with an initial program of up to 2,000 meters. Four diamond drill holes for a total of just over 1,000 metres have now been completed which concludes Phase One of the drill program. GPS will provide further updates upon receiving assay results from the laboratory.
Yeoval Goodrich Project Overview
The Project consists of two tenements, EL 8538 and EL 9243 (Figure 2).
The Yeoval Project is located approximately 70 kilometres northwest of Orange in central New South Wales and sits within the geological setting of the Macquarie Arc. The tenements cover an area of approximately 290 square kilometres. The area is underlain by granites, granodiorites and volcanics, and more than 60 historic mine workings occur within the project. The project area is readily accessible via sealed and unsealed roads and is adjacent to railway infrastructure.
The Goodrich Mine is a historic copper gold mine and was mined between 1868 and 1912. Mt Rose is located approximately two kilometres south from the Goodrich mine (Figure 3) and limited mining occurred during 1886.
The many gold-copper showings in the Yeoval district have been explored almost continuously since the 1960s, though mostly at shallow levels only, including completing both reverse circulation (RC) and diamond drill holes. Most of this exploration was carried out prior to the Discovery 2000 airborne magnetics and radiometrics becoming available for parts of the Lachlan Fold Belt including the Yeoval district.
Copper, gold and other base metal mineralization is widespread in the region and the main mineralization styles include porphyry style gold-copper mineralization.
Peeyush Varshney, CEO, commented:
"Completing the first stage of our earn-in agreement marks a pivotal milestone for GPS at Yeoval Goodrich. We are increasingly confident that a previously unrecognized porphyry copper-gold system may be hosted here.
With Phase One of the drill program having been completed we eagerly look forward to the assay results and additional geological modelling with a view to further advance the Project.”
