Commenting on the results, Wojtek Wodzicki, President and CEO stated "The drill holes released today were the final holes of this year's program, which successfully extended both the Fenix and Alicanto Zones and confirmed them as important high grade satellites to the core Condor high-grade Zone. The Los Helados system continues to deliver positive surprises.
In addition to drilling, we completed a comprehensive targeting exercise, which used detailed geophysical surveys and geological mapping completed this season to generate a number of new targets with signatures similar to those associated with the Condor, Fenix, and Alicanto Zones. We believe that Los Helados continues to have potential for additional discoveries."

Mineralized zones within the Los Helados deposit are bulk porphyry-style zones and drilled widths are interpreted to be essentially true widths. |
Copper Equivalent (CuEq) for drill intersections is calculated based on US$ 3.50/lb Cu, US$ 1,700/oz Au and US$ 20/oz Ag, with metallurgical recoveries of 88% for copper, 76% for gold and 60% for silver based on a comprehensive program of metallurgical testwork. The formula is: CuEq % = Cu % + (0.6117 * Au g/t) + (0.0057 * Ag g/t). |
Hole LHDH085 was intended to test for the eastern extension of the Fenix Zone towards the Condor Zone. It appears to have just clipped the eastern edge of the Fenix Zone between 668m and 902m, including a section from 732m to 818m that returned 0.76% CuEq. The rest of the hole intersected grades typical of the Los Helados breccia surrounding the high-grade breccia zones, with over 1,000m at 0.43% CuEq.
Hole LHDH086-1 was a daughter hole kicked off from LHDH086 at a depth of 420m and angled towards the east. It intersected the edge of the Alicanto Zone starting at about 860m, between 30 and 40m southeast from the intersection in LHDH083 (122m at 1.05% CuEq - see News Release dated January 26, 2023). Shallower in the hole, LHDH086-1 intersected a gold-rich section of 160m at 0.80 g/t Au, anchored by a 4m section of 11.16 g/t Au. This gold-rich zone was also intersected in holes LHDH083 and LHDH086-2 and its full extent, orientation and size remain to be determined.
Hole LHDH086-2 was kicked off LHDH086 at a depth of 430m in order to test the Alicanto Zone extension at depth beneath LHDH078. The hole intersected a 26m interval of elevated gold grades from 574m to 600m at 0.46 g/t Au which corresponds to the aforementioned gold zone in LHDH086-1. From 848m to 1,222m the hole intersected mineralized breccia, with a 40m section of 0.83% CuEq from 1,182m corresponding to the main high-grade zone 260m below the intersection in LHDH078. This interval also contained elevated molybdenum consistent with the molybdenum grades typical of the Alicanto Zone. Below this depth the hole encountered a series of late-mineral dykes which are typically low grade, including a dyke from 1,324m to the end of the hole. The true width of these dykes is much less than the drilled width, as they are sub-vertical. The full extent of the Alicanto Zone in this area remains untested.
Hole LHDH087 was planned to test the western extension of the Fenix Zone, to the west of intersections in holes LHDH076, LHDH081-2 and LHDH084. The breccia was intersected from 1,219m to 1,464m but at 0.47% CuEq was lower grade than the eastern holes. From 1,464m to the end of the hole at 1,523.6m the hole intersected a low-grade, late-mineral dyke and it ended before reaching the depth of the high-grade zone at the end of LHDH081-2 (63.8m at 1.25% CuEq - see News Release dated April 13, 2003). Hole 87 also intersected a high-grade gold vein, returning 4m at 17.93 g/t Au from 1,130m. Although this hole appears to have passed to the west of the Fenix Zone, it remains open to the north, south, at depth and there remains an undrilled gap to the east towards the Condor Zone at depth.
Hole LHDH088 was lost above its target in the Fenix zone at a depth of 300m. This hole was not analyzed.
The Fenix zone remains open and delineation of the size and grade of this zone will require additional drilling.
In addition to the drill program, the Company completed detailed geophysical surveys including drone magnetometry, magneto-tellurics (MT), and 3D IP, as well as a comprehensive structural mapping program, all designed to assist in targeting higher grade mineralization similar to that seen in the Condor, Fenix, and Alicanto Zones. The program has highlighted three areas with similar geological and geophysical signatures.
- The Aleksita target is an area of strong surface alteration and strongly anomalous copper, gold and molybdenum located just south of the main Los Helados deposit that lies within the main structural corridor that runs from Los Helados south to Lunahuasi and Filo and is believed to be an important control on mineralization in all three systems. Of note are areas of anhydrite and gypsum cemented breccia similar to those seen above the Condor zone. Anhydrite is associated with high grade mineralization in the Condor, Fenix and Alicanto zones and the occurrence of gypsum cemented breccias is considered a potential indicator of mineralization at depth. The area is underlain by a low resistivity signature similar to that coincident with the Condor, Fenix and Alicanto Zones. This target has not been drill tested.
- The Fenix-Alicanto Bridge is an area of low resistivity that runs along the western margin of the Los Helados-Filo del Sol structural corridor, between the Fenix and Alicanto Zones, in an area that has not been fully drill tested. Both the Fenix and Alicanto Zones are associated with low resistivity zones.
- The northeast extension is an area of strong alteration and brecciation to the northeast of the main Los Helados deposit.
NGEx Minerals is a copper and gold exploration company based in Canada, focused on exploration of its Los Helados copper-gold project located in Chile's Region III and the nearby Lunahuasi copper-gold-silver project located approximately 12 kilometres to the southwest in San Juan Province, Argentina.

Los Helados and Lunahuasi lie along the same major north-northeast trending structure that also controls the Filo del Sol deposit.
NGEx Minerals is the majority partner and operator for the Los Helados Project, subject to a Joint Exploration Agreement with Nippon Caserones Resources Co., Ltd. which is the 49% owner of the Caserones open pit copper mine located approximately 15km north of Los Helados. Lundin Mining Corp. holds the remaining 51% stake in Caserones.
The Company is listed on the TSXV under the trading symbol "NGEX". NGEx Minerals is part of the Lundin Group of Companies.
The scientific and technical disclosure for the Los Helados Project included in this news release have been reviewed and approved by Bob Carmichael, B.A.Sc., P.Eng. who is the Qualified Person as defined by NI 43-101. Mr. Carmichael is Vice President, Exploration for the Company.
Samples were cut at NGEx Minerals' operations base in Copiapó, Chile by Company personnel. Diamond drill core was sampled in 2 metre intervals (except where shortened by geological contacts) using a rock saw. Core diameter is a mix of HQ and NQ depending on the depth of the drill hole. Samples were bagged and tagged and packaged for shipment by truck to the ALS preparation laboratory in Copiapó, Chile where they were crushed and a 500g split was pulverized to 85% passing 200 mesh. The prepared samples were sent to the ALS assay laboratories in either Lima, Peru or Santiago, Chile for copper, gold and silver assays, and multielement ICP and sequential copper analyses. ALS is an accredited laboratory which is independent of the Company. Gold assays were by fire assay fusion with AAS finish on a 30g sample. Copper and silver were assayed by atomic absorption following a 4-acid digestion. Samples were also analyzed for a suite of 49 elements with ME-MS61 and a sequential copper leach analysis was completed on each sample with copper greater than 500ppm (0.05%). Copper and gold standards as well as blanks and duplicates (field, preparation and analysis) were randomly inserted into the sampling sequence for Quality Control. On average, 9% of the submitted samples are Quality Control samples. No data quality problems were indicated by the QA/QC program.
