VANCOUVER, BC, Feb. 28, 2022 /CNW/ - NGEx Minerals Ltd. (TSXV: NGEX) ("NGEx Minerals" or the "Company") is pleased to report initial drill results and an update on its ongoing drill program at the Valle Ancho copper-gold project in Catamarca Province, Argentina (the "Valle Ancho Project"). Highlights are listed below. View PDF

  • Drill hole VADH001 which tested the Nordin Gold Target returned 150m at 1.05 g/t Au from surface. The entire intercept is in oxidized rock.
  • Drill hole VADH002 intersected 0.63 g/t Au over 198m from surface in oxidized rock, including a higher-grade interval of 0.90 g/t Au over 70m.
  • Mineralization is associated with closely spaced quartz veinlets and is consistent with the style of mineralization seen in the nearby Maricunga District in Chile.
  • A total of approximately 2,750 metres in 8 holes has been completed to date of the planned 3,000 metre Valle Ancho drill program and additional assay results are pending.

Wojtek Wodzicki, President and CEO, commented "We are pleased with these initial drill results from the Nordin target which improve upon and extend the results seen in historical RC drilling. We are encouraged by the consistent grade distribution within the drill holes and the fact that the mineralization starts at surface and is oxidized to at least 200 metres depth.  The Valle Ancho project has many of the same geological characteristics that we saw in the early days of our previous discoveries in the Vicuña District, and we are very pleased to be drill testing some of the exciting targets resulting from our earlier reconnaissance work and look forward to reporting further drill results from La Quebrada and Anomalia 4 in the coming weeks."

*Mineralization at Nordin is associated with sheeted and stockworked quartz vein zones and drilled widths are thought to be approximate true widths, however additional drilling is required in order to confirm the true widths of the drill intersections reported here.

Nordin Target

The Nordin target is an area of strong hydrothermal alteration and gold-bearing banded quartz veins and hydrothermal breccias surrounded by younger gravel cover and thin volcanic flows.  The alteration is typical of the upper levels of an epithermal gold system and similar to that seen in some of the major deposits of the Maricunga Gold Belt located just across the border into Chile. 

Drill hole VADH001 returned 150m at 1.05 g/t Au from surface.  The entire intercept is in oxidized rock. VAD001 was drilled from the same collar and parallel to an historic shallow reverse circulation hole which reported 84m at 1.15 g/t Au, and extended the mineralization seen in that hole by 42 metres. 

Drill hole VADH002, collared 75m west of VADH001 and drilled in the other direction, intersected 0.63 g/t Au over 198m from surface in oxidized rock, including a higher-grade interval of 0.90 g/t Au over 70m.  This hole was a twin of an historic reverse-circulation hole which reported 1.02 g/t Au over 62m from surface, within a broader zone of 0.73 g/t Au over 110m, extending the mineralized zone by 88 metres  

Mineralization in both holes is associated with closely spaced quartz veinlets and is consistent with the style of mineralization seen in the nearby Maricunga District in Chile.  The historic RC drilling combined with surface sampling has outlined an area of 300m x 750m with oxidized gold mineralization occurring in drillholes and surface trenches.  The two diamond drill holes reported here confirm and extend the mineralization encountered in historic drilling, and provide strong evidence for the occurrence of a significant oxide gold zone at Nordin.  Additional drilling is planned in order to establish the size and geometry of this mineralized system.

La Quebrada

La Quebrada is a porphyry copper-gold target located approximately 15 km southeast of Nordin.  The alteration in La Quebrada outcrops in an erosional window through younger cover rocks and extends over an area of approximately 2.5 km by 1 km.   The outcropping mineralization has the characteristics of a leached cap of a porphyry system, with the presence of oxide minerals including jarosite, goethite and hematite and locally copper oxides.  Oxide mineralization occurs in veinlets and disseminated and is most intense in areas with a higher density of quartz veining.  The 174 rock chip samples taken by NGEx in 2019/2020 in the area average 0.5 g/t gold and 0.2% copper which is considered encouraging in an area where the rocks are oxidized and leached.  Leaching commonly removes copper which is mobile in a supergene environment and therefore even low-level copper numbers can be important indicators of mineralization at depth.  Higher gold and silver numbers were obtained from structurally controlled zones in the area with values ranging up to 8.57 g/t gold and 114 g/t silver.

During the current program, five holes were completed on the La Quebrada copper-gold target. These holes tested an area measuring approximately 1 kilometer by 0.5 kilometer which had strong surface alteration and geochemistry as well as a strong geophysical (chargeability) anomaly. Drill results are pending.

Anomalia 4

One hole is currently underway at Anomalia 4, a target area located approximately halfway between Nordin and La Quebrada.  The drill hole is targeting an area of sub-cropping silicified structures and hydrothermal breccias with strongly anomalous gold values ranging from 0.5 g/t to 7.07 g/t and silver values up to 580 g/t.   

An induced polarization geophysical survey completed last month outlined a large chargeability anomaly associated with this target.

About the Valle Ancho Project

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 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.  Of this amount approximately US$1.5 million was spent prior to the start of the current program with the remaining US$6.5 million expected to be invested over the current field season.

Reverse circulation drilling was completed on the Nordin target by Eldorado Gold Corporation during the 1995/1996 season.  NGEX has reviewed the original annual exploration report detailing the drilling and sampling methodology as well as the original assay certificates.  Samples were collected every two metres, and were split twice resulting in 1/8 of the original sample being retained for analysis.  Field duplicates were included in the sample batches, however no assay standards or blanks were included.  Analyses were completed by Bondar Clegg Inchcape Testing Services in North Vancouver, Canada.  Bondar Clegg Inchape was an accredited assay lab which was independent of Eldorado Gold Corporation.  Gold analyses were by fire assay fusion with AAS finish on a 30g sample.  In addition, NGEX has reviewed chips from the sample intervals.  Drilling, sampling and assaying was done to industry standards at the time, and NGEX has no reason to believe that the analytical data reported here is inaccurate, however the Company has not completed its own sampling to independently verify the assay results. 

Sample results reported above from the 2019/2020 NGEx program are grab samples from individual locations and are not associated with a length of width of the mineralized zone.  Samples were collected in the field by NGEx geologists, identified with sample tags and placed in plastic sample bags for transportation to the lab via truck.  Samples were delivered to the ALS prep lab in Mendoza, Argentina who sent a prepared sub-sample on to the ALS assay laboratory in Lima, Peru for analysis.  Samples were assayed for gold by fire assay and AAS on a 50g sample (Au-AA24), mercury by ICP-MS following aqua regia digestion (Hg-MS42) and a suite of 48 elements using ICP-MS and ICP-AES following a four-acid digestion (ALS ME-MS61L) with overlimit (>10,000ppm) copper samples re-analyzed with Cu-AA62.

Diamond drill core was sampled in 2 metre intervals (except where shortened by geological contacts) using a rock saw. 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 copper, gold and silver assays, and multi-element ICP and sequential copper analyses.  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 36 elements with ICP-ES. 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.

ALS is an accredited global analytical company which is independent of the Company.
