NGEx Drills 1,540m at 1.17% CuEq, Including 88m at 8.65% CuEq in Saturn Zone and 501m at 0.73% CuEq in Expanded Porphyry Deposit

About this update from Ngex Minerals Ltd.

VANCOUVER, BC, June 23, 2026 /CNW/ - NGEx Minerals Ltd. ("NGEx", "NGEx Minerals" or the "Company") (TSX: NGEX; OTCQX: NGXXF) is pleased to announce results of two drill holes from the Phase 4 drill program at its 100% owned Lunahuasi high-grade copper-gold-silver project in San Juan, Argentina. PDF Version Lunahuasi Geology Drill Plan 2026 June Highlights: Wojtek Wodzicki, President and CEO, commented, "Hole DPDH064 is one of the most important holes we have drilled, crossing the high-sulphidation system and continuing well into the adjacent porphyry deposit, highlighting the impressive scale and grade of Lunahuasi. This hole also confirms that the Lunahuasi porphyry includes a large breccia body with significant copper and gold grades. High-grade breccias are an important part of many notable porphyry deposits worldwide and the fact that we are seeing this style of mineralization in only our second hole into the Lunahuasi porphyry bodes well for the potential of the deposit." Table 1: Significant Intersections DPDH064 was drilled from the same platform as DPDH027 at an azimuth of 260o and dip of -46o to test the southern extent of the Saturn Zone and the adjacent porphyry deposit at depth. The Saturn Zone was intersected as expected between 572.00m and 660.00m, averaging 8.65% CuEq, including a very high-grade section of 15.65m at 30.13% CuEq starting at 583.35m, extending the zone by 70m to the southwest of DPDH021. Much like in hole DPDH027, characteristic porphyry vein types define a zonation towards the porphyry system, with D veins appearing at about 400 m, B veins around 900 m and A veins at around 1,000 m. The overprinting HS mineralization continues to a down-hole depth of 1,235m where a sharp transition to porphyry mineralization is indicated by a distinct change in copper mineralogy from enargite to chalcopyrite +/- bornite. This contact correlates well with the same transition in DPDH027 at 1,262m. The intensity of veining increases below the contact, and a thick section of early-mineral porphyry beginning at 1,350m corresponds with a sharp increase in copper and gold grades, confirming the conclusion from DPDH027 that the system includes several phases of porphyry intrusions, including a well-mineralized early phase. DPDH064 continues through a very strong stockwork of well mineralized A veins cutt...
