Commenting on the results Wojtek Wodzicki, President and CEO stated, "We are pleased with the results from this first pass exploration program on the Valle Ancho project. Today's results from the La Quebrada copper-gold target follow earlier positive results from the Nordin oxide-gold target. Results from La Quebrada are from wide-spaced reconnaissance-style drilling and demonstrate the presence of a large copper-gold system. We are also encouraged by the results of regional prospecting and target development work at La Austral which has identified a target of interest for potential future drill programs."

La Quebrada

La Quebrada is a porphyry copper-gold system located approximately 15 km southeast of the Nordin gold target.  Mineralization at La Quebrada outcrops in an erosional window through a thin screen of younger cover rocks and extends over an area of at least  0.5 km by 1 km, extending under the cover in all directions.   During the current program, five holes tested an area which has strong surface alteration and geochemistry as well as a strong geophysical (chargeability) anomaly at depth.  Three of the five holes intersected significant intervals of copper-gold mineralization consistent with a large porphyry system, and all three of these holes ended in mineralization.

Drill hole VADH003/3A returned 596.5m of 0.50% CuEq (0.23% Cu; 0.37 g/t Au; 1.4 g/t Ag) from 4.0m to the final depth of 600.5m.  The hole was oxidized to approximately 104m and intersected potassic alteration variably overprinted by quartz-sericite pyrite alteration with well developed quartz stockwork veining and occasional zones of hydrothermal breccia. Copper mineralization below the limit of oxidation is primarily chalcopyrite.

Drill hole VADH004 drilled 350 meters to the east of VADH003 did not return any significant gold or copper values and intersected primarily propylitic alteration locally overprinted by quartz-sericite-pyrite alteration and cut by weakly developed quartz-pyrite veining.

Drill hole VADH005 drilled 240 metres south of VADH003 was mineralized over its entire length, ending in mineralization at 271.0m.  The entire hole returned 271m of 0.32% CuEq (0.12% Cu; 0.26 g/t Au; 1.1 g/t Ag). Mineralization is associated with stockwork quartz-sulfide veining and sericite-chlorite alteration overprinting relict potassic alteration.

Drill hole VADH006 was collared 190m east of VADH005 intersected 423m of 0.40% CuEq (0.19% Cu; 0.27 g/t Au; 2.2 g/t Ag).  Mineralization is oxidized to a depth of approximately 62 metres and is associated with stockwork quartz sulfide veining and sericite-chlorite alteration.

Drill hole VADH007 was collared 620m southeast of VADH006 and tested a strong chargeability anomaly at depth. The hole intersected strong quartz-sericite-pyrite alteration but no significant gold or copper values, other than a 2m section of 5.35 g/t Au between 76m and 78m.

Anomalia 4

Anomalia 4 is an area located approximately halfway between Nordin and La Quebrada and is characterized by sub-cropping silicified structures and hydrothermal breccias and strong sericitic alteration underlain by a strong chargeability anomaly. Drill hole VADH008 tested this area and intersected quartz-sericite-pyrite alteration cut by quartz-pyrite and pyrite veins. Anomalous gold (up to 0.4 g/t Au) and copper grades (up to 0.36% Cu) do not extend over significant intervals.

Regional exploration

In addition to the drill program and local IP surveys, the Company completed an airborne magnetic survey covering the entire land package and a regional prospecting and target development program.  Encouraging results were obtained from the La Austral target which is located approximately 9 kilometres southeast of La Quebrada.  It was discovered by NGEx geologists in 2020 through follow-up of a stream sediment anomaly.  

Mineralization is associated with silica-alunite cemented breccia zones containing strongly anomalous gold. The breccias contain highly silified  angular clasts in a matrix of silica,  alunite, and jarosite.  Initial grab samples of the breccia zone returned values of up to 7.18 g/t gold and 777 g/t silver.  Three other samples returned values in excess of 1 g/t Au.  All samples were high in eptithermal pathfinder elements Hg-Te-Sb-As-Bi.  Further geological mapping and geochemical sampling was carried out in 2022 to define targets for possible future drill testing.

The Valle Ancho Project consists of two Exploration and Mining Reserve Areas held by the Province of Catamarca that cover approximately 1,000 km2 of highly prospective and underexplored ground on the Argentinian side of the Maricunga Gold Belt. More than 100 million ounces of gold have been discovered on the Chilean side of the border hosted in well known deposits such as Norte Abierto (Barrick-Newmont JV), whereas the Argentinian side has seen much less exploration despite having similar geology.

The project area was initially explored in the 1990's resulting in the identification of several interesting gold and copper-gold targets. Despite the encouraging results obtained by earlier explorers the area was not available for exploration for most of the last 20 years. The main targets lie along a major northwest trending structural corridor called the Valle Ancho Lineament. Many of the major deposits in the Andes are spatially related to similar northwest trending lineaments. 

The Company has an option to earn a 100% interest in the Valle Ancho Project from the government of the Province of Catamarca by completing approximately US$8 million in expenditures by December 2022. The Company anticipates that it will complete the expenditure commitment by year-end.


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 core of 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 Valle Ancho Project included in this news release has 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´s exploration camp in Catamarca, Argentina 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 Mendoza, Argentina 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 gold assays and multi-element ICP 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. Samples were also analyzed for a suite of 48 elements using a Super-Trace method ideal for exploration that consists of a 4-acid digest on 0.25g sample analyzed via ICP-MS and ICP-AES. Hg was determined by ICP-MS. 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.  Copper values in this news release have been converted to % from ppm values reported by the ICP analytical method.

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 80% metallurgical recoveries assumed for all metals. The formula is:  CuEq % = Cu % + (0.7083 * Au g/t) + (0.0083 * Ag g/t).
