Homase Pit Definition & JORC Exploration Plan

GoldStone advances Homase drilling, but updated resource estimate is still months away.

What the company is saying

GoldStone Resources Limited is highlighting the completion of pit-definition drilling at its Homase Mine in Ghana and the re-appointment of SEMS Exploration Services to manage the next phase of its JORC Mineral Resource evaluation and expansion. The company frames the results as 'encouraging,' citing specific drill intercepts such as 16 m @ 1.26 g/t and 5 m @ 2.76 g/t, and suggests that combining Pits 5 and 6 could improve logistics and stripping ratios. The narrative emphasizes the extension of mineralisation by approximately 850 m beyond Pit 4 and the identification of parallel zones, positioning these as evidence of significant exploration upside. CEO Emma Priestley characterizes the progress as foundational for extending mine life and strengthening the resource base, while Dr Bob Foster, Non-Executive Director, is named as the Competent Person who approved the technical content. The announcement stresses a structured, multi-phase drilling program and targets an updated JORC resource estimate in H1 2027, but does not provide current production or financial figures. The tone is optimistic and forward-looking, focusing on potential rather than immediate value realization.

What the data suggests

The company reports completion of approximately 2,700 m of pit-definition drilling, with significant results including 16 m @ 1.26 g/t (26MLRC007), 5 m @ 2.76 g/t (26MLRC006), and 8 m @ 2.17 g/t (26MLRC017). The northern extension of mineralisation is confirmed for about 850 m beyond Pit 4, with the mineralised zone up to 200 m wide. Southern sector drilling returned intercepts such as 13 m @ 0.61 g/t (26MLRC021) and 7 m @ 1.02 g/t (26MLRC023). The current JORC Mineral Resource stands at 602,000 ounces (10.6 Mt @ 1.77 g/t Au), but this figure is from 2012 and does not account for mining since 2021. The new resource expansion program includes 32 holes totaling ~7,770 m (5,300 m RC, 2,470 m diamond), with a 23-hole priority phase of ~5,200 m. Drilling targets four main areas, with specific meterage allocated to each. Historical production from Akrokeri Ashanti Mine is cited as 75,000 ounces at 24 g/t, and Homase Pit as 52,000 ounces at 2.5 g/t. No updated resource or production figures are disclosed, and the main catalyst—a revised JORC resource—is not expected until H1 2027. The technical disclosure is detailed, but the absence of current resource or financial data limits assessment of near-term economic impact.

Analysis

The announcement provides detailed and credible technical data on recent drilling at the Homase Mine, including specific assay results and the scope of the ongoing resource expansion programme. These realised facts support the company's operational progress. However, the narrative inflates the signal by emphasizing potential future benefits (such as combining pits for logistical gains and unlocking wider project potential) without providing quantitative evidence or technical studies to substantiate these claims. The most material catalyst—the updated JORC Mineral Resource estimate—is not expected until H1 2027, making the timeline for tangible benefits long-term. The capital intensity is high, with a large drilling programme underway, but there is no immediate earnings or resource update impact. The tone is optimistic and forward-looking, but the gap between realised progress and projected outcomes is notable, especially as the current resource estimate is outdated and does not reflect recent mining. Overall, the announcement is technically robust but somewhat promotional in framing future potential.

Risk flags

• ●The current Mineral Resource estimate of 602,000 ounces is from 2012 and does not reflect depletion from mining since 2021, creating uncertainty about the true remaining resource and near-term mine life.
• ●The timeline to an updated JORC Mineral Resource estimate is long, with completion only targeted for H1 2027, which delays any re-rating or economic assessment based on new data.
• ●Operational execution risk is elevated due to the scale of the planned drilling program (32 holes, ~7,770 m), which requires sustained technical, logistical, and financial resources to complete as planned.
• ●The announcement does not provide current production, cost, or financial figures, making it difficult for investors to assess the company's present economic position or cash runway.
• ●Forward-looking claims about combining pits and logistical benefits are not substantiated by technical or economic studies, so the actual impact on project economics remains speculative.

Bottom line

GoldStone's update demonstrates technical progress at Homase, with detailed drill results and a clear plan for resource expansion, but the lack of a current resource estimate or production figures means investors cannot yet assess the project's present value or near-term cash generation. The main catalyst—an updated JORC Mineral Resource estimate—is not expected until H1 2027, so any re-rating or investment case based on resource growth is months away. The company's narrative is credible in terms of operational detail, but aspirational regarding future logistical and economic benefits, which remain unproven until further studies are completed. Investors should focus on the delivery of the full drilling program and the eventual updated resource statement as the next actionable milestones. For now, the most important takeaway is that while exploration momentum is real, value realization is not imminent and depends on successful execution and confirmation of resource growth.

Announcement summary

(AIM:GRL) GoldStone Resources Limited provided an update on pit-definition drilling at its Homase Mine in Ghana and announced the re-appointment of SEMS Exploration Services to lead the next phase of its JORC Mineral Resource evaluation and expansion programme. The company is building on its 602,000 ounce Mineral Resource reported in November 2012 under JORC Code (2004), within a 4.4 km-long structural zone that is part of the >8 km Homase Trend. The pit-definition drilling programme, expanded to approximately 2,700 m as of 30 September 2026, targeted proposed Pits 5 and 6 and extensions to existing oxide mineralisation. Significant drilling results include: 16 m @ 1.26 g/t from 11 m (26MLRC007), 5 m @ 2.76 g/t from 19 m (26MLRC006), 8 m @ 2.17 g/t from 44 m including 2 m @ 4.04 g/t (26MLRC017), 8 m @ 1.49 g/t from 25 m (26MLRC002), 16 m @ 0.99 g/t from surface (26MLRC016), and 24 m @ 0.68 g/t from 41 m to end of hole (26MLRC018). The results suggest Pits 5 and 6 might be combined, with potential benefits in logistics and stripping ratio. Drilling has demonstrated gold mineralisation at depth in areas where surface sampling was weak, indicating further exploration potential. The northern drilling extended mineralisation ~850 m beyond Pit 4, with the mineralised zone up to 200 m wide, and confirmed parallel mineralised zones. RC assay results in some cases showed higher gold content at depth than at surface, such as 7 m @ 1.21 g/t (26MLRC001) and 8 m @ 1.49 g/t (26MLRC002). In the southern sector, three of the first five holes intersected 7 to 13 m of gold at 0.61 to 1.02 g/t, including 13 m @ 0.61 g/t (26MLRC021), 7 m @ 1.02 g/t (26MLRC023), and 12 m @ 0.65 g/t (26MLRC024). SEMS, which prepared the 2012 Mineral Resource estimate, has been re-appointed to manage the JORC Mineral Resource evaluation and expansion programme at Homase. The Phase 1 resource expansion programme comprises 32 RC and diamond drill holes totalling approximately 7,770 m across four target areas, with an initial 23-hole priority programme totalling approximately 5,200 m. The full programme includes 5,300 m of RC drilling and 2,470 m of diamond drilling. Planned drilling includes 14 RC holes (~2,250 m) for Pits 5 and 6, two RC-collar diamond holes (~800 m) for Pit 4, ten RC diamond holes (~2,475 m) for Pits 1 and 2, and six RC diamond holes (~2,245 m) for Pit 3. The Homase Mineral Resource as of 22 November 2012 was 10.6 Mt at 1.77 g/t Au for 602,000 ounces (Measured 1.61 Mt @ 2.24 g/t, Indicated 4.41 Mt @ 1.73 g/t, Inferred 4.56 Mt @ 1.64 g/t), using a 0.5 g/t Au cut-off. The company is targeting an updated JORC Mineral Resource estimate for H1 2027. The broader Homase Trend corridor could be up to 1,500 m wide, with further exploration considered towards the Akrokeri Gap and former Akrokeri Underground Mine. Historical production includes approximately 75,000 ounces at 24 g/t from Akrokeri Ashanti Mine and approximately 52,000 ounces at 2.5 g/t from Homase Pit. Emma Priestley, Chief Executive Officer, stated that the progress at Homase is an important step in strengthening the mining operation and unlocking wider project potential. Dr Bob Foster, Non-Executive Director, reviewed and approved the technical information as a Competent Person under the JORC Code (2012). GoldStone also has an interest in a gold project in Sierra Leone.
