Management reported that drilling has defined copper mineralisation across more than 4km² within a broader 46km² sedimentary basin, with multiple high-grade manto-style horizons remaining open in several directions. The company is advancing a 150-metre drill spacing programme ahead of a maiden Mineral Resource Estimate (MRE), targeted for the first half of 2027, while geophysical AMT surveys continue to identify compelling exploration targets beyond the current resource area. Initial metallurgical test work across sulphide, mixed and oxide domains has not identified any material processing concerns, supporting confidence in the project's development potential. Management also outlined early mining studies, suggesting favourable underground mining economics based on the deposit's exceptional thickness compared with global sediment-hosted copper analogues. Alongside the continued development of the flagship Marimaca Oxide Deposit (MOD), the company believes Pampa Medina has the potential to become a transformational Tier 1 copper discovery, with significant resource growth opportunities and potential operational synergies between the two projects. Overall, the presentation highlighted Marimaca Copper's exploration success, growth strategy and long-term value creation potential as it advances one of Chile's most promising emerging copper districts.
