VANCOUVER, BC, April 13, 2023 /CNW/ - NGEx Minerals Ltd. (TSXV: NGEX) ("NGEx Minerals" "NGEx" or the "Company") is pleased to report additional assays from four holes drilled at the Los Helados copper-gold project located in Region III, Chile. These results contain some of the highest grades ever seen at Los Helados, including molybdenum grades which are significantly higher than any intersected previously, and demonstrate that the Fenix Zone is rapidly growing into a second major centre of mineralization. Most of the new drilling into the Fenix and Alicanto Zones is outside of the current Los Helados Mineral Resource and both zones remain open to expansion in several directions. PDF Version     

  • LHDH081-2: Fenix Zone:
    • 343.8m at 0.90% CuEq, including 63.8m at 1.25% CuEq
  • LHDH081-3: Fenix Zone:
    • 234.0m at 0.90% CuEq, including 28.0m at 1.49% CuEq
  • LHDH084: Fenix Zone:
    • 390.0m at 1.13% CuEq
  • LHDH086: Alicanto Zone:
    • 104.0m at 0.69% CuEq

Commenting on the results Wojtek Wodzicki, President and CEO stated "The 2023 exploration program is shaping up to be the most successful and impactful in the Company's history. Years of hard work and exploration experience are coming together to deliver a series of high impact discoveries. Last week we released high-grade results from the new Potro Cliffs discovery which is the fourth major system discovered in the Vicuña District. Today's results from Los Helados, 9 kilometres to the north of Potro Cliffs, continue to confirm the Fenix and Alicanto Zones as significant new centres of high-grade mineralization. Both of these zones have considerable room to grow, and offer the potential for a meaningful expansion of the Los Helados resource. We are particularly encouraged by the copper and molybdenum grades of these new zones, which are significantly higher than the averages seen to date. This season's drilling is proving the exploration adage that 'Big systems tend to grow and deliver continued positive surprises."

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).


LHDH081-2 was a daughter hole kicked off LHDH081 at a depth of 780.0m and angled towards the southwest.  It was drilled to a final depth of 1,549.8m, intersecting the Fenix Zone between 35m and 90m to the west of LHDH081. The zone remains open to the west of this hole. 

The Fenix Zone was intersected over a 343.8m interval from 1,206.0m to 1,549.8m and consists of a clast-supported hydrothermal breccia with a matrix composed of anhydrite, chalcopyrite, quartz and biotite. The average grade of this interval is 0.81% Cu, 0.12 g/t Au and 204ppm Mo which is considerably higher than the Los Helados deposit average.

The hole ended due to rig capacity in high-grade mineralization, with the final 20m averaging 1.36% CuEq (1.27% Cu, 0.11 g/t Au, 3.1 g/t Ag) plus 1540ppm Mo. Note that Mo is not currently included in the CuEq calculation.

LHDH081-3 was kicked off hole LHDH081-2 at a depth of 786.6m and angled towards the south to investigate the gap between holes LHDH081 and LHDH076. The hole encountered the Fenix Zone at a depth of 1,032.0m and drilled it to a final depth of 1,266.0m resulting in a partial intersection of 234.0m at an average grade of 0.76% Cu and 0.22 g/t Au. The hole was terminated due to technical complications on the part of the drill contractor.

The Fenix Zone in this hole was split by a low-grade porphyry dyke from 1,186.0m to 1,238.0m (52m) resulting in dilution to the overall intersection. This dyke was also intersected in holes LHDH076 and LHDH081 and its true width is estimated at 20-25m, indicating that it has a disproportionate impact on the overall grade of the intervals due to the angle of intersection with the drill hole.

LHDH084 was drilled from south to north across the Fenix Zone in the opposite direction from the LHDH081 series holes. The hole terminated in high-grade mineralization due to rig capacity at 1,500.0m, resulting in a partial Fenix Zone intersection of 390.0m grading 1.02% Cu, 0.15 g/t Au and 187ppm Mo.

The southern contact of the Fenix Zone was intersected at a depth of 1,110.0m which puts it 250m due south of the northern contact as intersected in hole LHDH081, establishing a minimum horizontal width for the zone.  This hole ended 100m to the southeast of the end of LHDH081-2.

LHDH086 intersected the Alicanto Zone from 938.0m to 1,042.0m and returned 0.60% Cu and 0.14 g/t Au, including a higher-grade interval of 44.0m with 0.75% Cu and 0.22 g/t Au.  This intersection is 60m to the west of the discovery hole, LHDH078, and the zone remains open in several directions beyond it.


Los Helados contains at least three distinct high-grade zones hosted within well-defined structural corridors that cross cut the large breccia body that hosts the deposit; the Alicanto Zone, the Condor Zone, and the Fenix Zone. 

The current drilling program is focused on defining the geometry and size of the Alicanto and Fenix Zones. Holes currently completed with assays pending, or in progress are outlined below:

Holes Completed and in Progress

LHDH085: Drilling from north to south to intersect the Fenix Zone 140m east of LHDH076. Complete, assays pending.

LHDH086-1: Target 100m step-out to the east of LHDH078 on the Alicanto Zone. Complete, assays pending.

LHDH086-2: Target 100m step-out to the south of LHDH078 on the Alicanto Zone. Complete, assays pending.

LHDH087: Target to west of LHDH081-2 and LHDH084 on the Fenix Zone. In progress.

LHDH088: Drilling from north to south, across the Fenix Zone between LHDH076 and LHDH084. In progress.


The final two holes of the program are underway, supported by a directional drilling crew from STYR SpA, a leading provider of Devico directional drilling technology. The Company has also completed a comprehensive geophysical program to assist in targeting higher grade mineralization including a 3D IP/Resistivity survey, a drone magnetics survey, and a magneto-telluric survey. Results are currently being processed and will help guide a comprehensive interpretation combined with the results of the current drilling program.

NGEx Minerals holds the large-scale Los Helados copper-gold deposit, located in Chile's Region III, as well as the Potro Cliffs and 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. NGEx Minerals' near-term focus is on expanding the high-grade core of Los Helados and drilling the Potro Cliffs target located between Los Helados and the Filo del Sol deposit. 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.
