NGEx Minerals Discovers Third High-Grade Zone at Los Helados
VANCOUVER, BC, June 12, 2022 /CNW/ - NGEx Minerals Ltd. (TSXV: NGEX) ("NGEx Minerals" "NGEx" or the "Company") is pleased to report the discovery of a third zone of high-grade copper-gold mineralization at the Los Helados project, Chile. This new zone, called the Alicanto Zone, is located 550m north of the Condor Zone and is related to a new porphyry center. The Alicanto Zone was discovered by hole LHDH078, which was targeting a geophysical anomaly north of hole LHDH062 (256m at 0.56% CuEq). View PDF
- Drillhole LHDH078 returned 474.8m at 0.61% CuEq from 566m including:
- 100.0m at 1.20% CuEq from 844m
- And 0.56% CuEq over the last 20.8m of the hole
- This intersection constitutes the discovery of a third distinct zone, the Alicanto Zone, of high-grade mineralization within the overall Los Helados deposit
- The Alicanto Zone remains completely open to expansion in all directions
Commenting on the results Wojtek Wodzicki, President and CEO, stated "Hole 78 has given us exactly what we were looking for this season – the discovery of a brand new zone of high-grade mineralization associated with the giant Los Helados system. We are naming this the Alicanto Zone after a mythical bird of the Atacama Desert which feeds on gold and silver. Legend has it that miners who follow an Alicanto will find rich mineral outcrops or treasure. Following reinterpretation of the geology in hole LHDH062, we realized that the intersection in that hole likely represented a new porphyry center adjacent to the Condor Zone, and this has been confirmed with the discovery of the Alicanto Zone. This discovery is a direct result of the re-interpretation of the geology at Los Helados, and confirmation that we are on the right track in our quest for additional high-grade material. Our improved understanding of the controls on mineralization has given us a clear, testable model which provides huge upside for expanding the high-grade at Los Helados as we continue to drill the extensions of the Condor, Fenix and now the new Alicanto Zone."

Hole LHDH078 was a vertical hole collared 275m northwest of LHDH062 which is the closest hole to it. Hole LHDH062 is one of our longest intersections, with 1,345m at 0.39% CuEq (0.32% Cu, 0.10 g/t Au, 1.1 g/t Ag) including a 256m section at 0.56% CuEq (0.46% Cu, 0.16 g/t Au, 1.9 g/t Ag). This was previously our most northerly hole into the deposit, and convinced us that we had not yet reached the edge of the deposit. As we worked through a reinterpretation of the deposit geology late last year, we realized that LHDH062 had likely intersected a separate porphyry center, and that there was potential to expand this to the northwest.
The high-grade Alicanto Zone intersected in hole LHDH078 is comprised of a hydrothermal breccia developed in Permo-Triassic rhyolite country rock. The breccia matrix is composed of very distinct purple anhydrite containing large clots of coarse chalcopyrite, and is visually very similar to the Fenix Zone located some 900m to the southwest. Breccia fragments are cut by both A-type veins and quartz-molybdenite B-type veins.
The Alicanto Zone occurs within the northernmost of three parallel mineralized structural corridors which trend west-northwest and are comprised of phreatic and hydrothermal breccias associated with different copper-gold porphyry intrusion phases. These corridors host, from south to north, the Fenix, Condor and now Alicanto Zones, each of which is open to expansion at depth and along the strike of the corridors.
The 2022 drilling program was initially focused on defining zones of high-grade mineralization within the footprint of the overall Los Helados deposit and expanding the deposit's high-grade core. Reinterpretation of the deposit geology suggested that the deposit contained at least two distinct high-grade zones hosted within well-defined structural corridors. Suspicion of a third corridor has now been confirmed with hole LHDH078. The drill program, including completed and planned holes, is outlined below:
Holes Completed
LHDH073: Results previously released; infills a gap between existing holes and extends the Condor Zone at depth
LHDH074: Results previously released; infills a large gap between existing holes and extends the Condor Zone
LHDH075: Results previously released; extends the Condor Zone to the south
LHDH076: Results previously released; tested gap between the Condor Zone and the Fenix Zone; extension of the Fenix Zone
LHDH078: Results released today; tested for confirmation and extension of a third structural corridor; discovered high-grade Alicanto Zone as confirmation of this third corridor
LHDH077: Assays pending; testing southern extension of Condor Zone
LHDH080: Assays pending; testing low resistivity anomaly
Holes in Progress
LHDH079: Testing depth extension of Condor Zone
LHDH081: Testing continuity and extension of Fenix Zone at depth
LHDH082: Testing depth extension of Condor Zone in eastern sector of the deposit.
Drilling is planned to continue until the current holes are completed in late June. The data generated from the current drill program at Los Helados will form the basis for a revised geological model. The drill program will also provide samples for additional detailed metallurgical test work, which will allow for optimization of process flowsheets and a better understanding of variability within the orebody. The Company is excited to resume drilling in September following a short break during the Southern Hemisphere winter, with a goal of expanding the three zones by systematic testing for extensions guided by the new structural corridor interpretation.
NGEx Minerals is a copper and gold exploration company based in Canada with projects in Chile and Argentina. NGEx Minerals holds the large-scale Los Helados copper-gold deposit, located in Chile's Region III, as well as the Valle Ancho Projects located in Argentina. 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. While NGEx Minerals' near-term focus will be on drilling the high grade zones at Los Helados and exploration at the Valle Ancho Project, it remains open to adding quality projects to its portfolio as part of its overall growth strategy. The Company is listed on the TSXV under the trading symbol "NGEX".
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 Resources' 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 multi-element 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.
Mineralized zones within the Los Helados deposit are bulk porphyry-style zones and drilled widths are interpreted to be very close to 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).
