NGEx Minerals begins phase 4 drilling at Lunahuasi

Mr. Wojtek Wodzicki reports NGEX KICKS OFF PHASE 4 DRILL PROGRAM AT LUNAHUASI NGEx Minerals Ltd. has begun the phase 4 drill program at its 100-per-cent-owned Lunahuasi property, located in San Juan, Argentina. The phase 4 program follows a highly successful phase 3 program completed in the first half of 2025, which continued to deliver some of the highest-grade copper, gold and silver intercepts drilled anywhere in the world. Phase 3 drilling consistently intersected high-grade vein mineralization across considerable widths and strike length, improving the geological understanding of the structures that form the original Lunahuasi discovery, confirmed the discovery of a new copper-gold porphyry system at Lunahuasi (see news release dated May 21, 2025), and discovered ultrahigh-grade gold in quartz veins representing a fourth, distinct type of mineralization at the project (see news release dated July 8, 2025). Wojtek Wodzicki, president and chief executive officer, commented: "We are very excited to kick off our fourth drill program at Lunahuasi, which aims to build on the successes of the phase 3 program. Drilling this season is designed to further test the four styles of mineralization identified to date while also exploring for new high-grade zones and continuing to expand the boundaries of the deposit, which remains open in all directions. With the recent completion of a significantly oversubscribed private placement financing of $175-million added to our substantial existing treasury, we are fully funded and well positioned to execute our current plan and will have flexibility to expand the program if justified." The new drill program has commenced with six drill rigs currently turning and two more starting soon. With over 2,000 metres drilled already, the company is well on the way to accomplishing its targeted program, which will consist of up to 25,000 metres of diamond drilling to follow up on 43,249 metres drilled since discovery of the deposit in March, 2023. The planned program will consist of three targeted ranges of drill spacing to accomplish different objectives: short-range resource definition, mid-range stepout and long-range exploration. Initial assay results are expected toward the end of Q4 2025, but exact timing will depend on drilling rates and assay turnaround times. About NGEx Minerals Ltd.
