Announcement PDF ASX Announcement 28 October 2024 S2 Resource’s encouraging first drill hole at Glenlogan 300m of hydrothermal alteration and disseminated pyriteii Legacy Minerals Holdings Limited (ASX: LGM, “LGM”, “the Company” or “Legacy Minerals”) is pleased to report a drilling update at the Glenlogan Project (EL9614) completed by earn-in partner S2 Resources Ltd (S2R) i. The Glenlogan Project Drilling ii • Main magnetic anomaly is an alkaline gabbroic diorite, intruded by later quartz diorite porphyry (“QDP”) dykes that increase in abundance downhole. • The last 300 metres of the hole contains: o increasing QDP dykes, hydrothermal alteration and disseminated pyrite, o o increasingly anomalous levels of copper, gold and other chalcophile/pathfinder elements widespread presence of very fine-grained late magmatic/hydrothermal chalcopyrite intergrown with propylitic-style alteration assemblage. • Late magmatic/hydrothermal chalcopyrite and consequent elevated copper in and around QDP dykes suggests they may be fertile and may represent the fringes of a nearby potentially mineralised porphyry intrusion as yet untested by drilling. • Geophysical methods being assessed to assist in targeting potential future drillhole. Management comment – Legacy Minerals CEO & Managing Director, Christopher Byrne said: “It’s positive to see that the first drill hole assays and petrography completed at Glenlogan by S2 Resources show characteristics consistent with porphyry copper-style alteration. The implication is that we may be near a potentially mineralised intrusive that has yet to be tested by drilling. The widespread presence of chalcopyrite (copper sulphide) and increased levels of porphyry pathfinder elements towards the end of the hole is very encouraging, considering the geological setting in the Lachlan Fold Belt, and the proximity to the globally significant Cadia-Ridgeway Mine operated by Newmont. The Farm-in agreement with S2 Resources provides our shareholders funding security and discovery exposure to a major, potential company-making greenfield porphyry discovery. Legacy Minerals is pleased to see the great progress S2 Resources has made on the Glenlogan project while LGM continues to focus on its wholly-owned projects. As S2 Resources continues to advance the Glenlogan Project, we look forward to updating our shareholders on the next stages.” About S2 Resources • The S2 Resources team has extensive experience in discovering and developing world-class deposits, including the Thunderbox 4Mtpa iii open pit gold mine (ASX: NST) and the Nova 1.5Mtpa iv underground nickel-copper mine (ASX: IGO).
