VANCOUVER, July 3, 2018 /CNW/ - NGEx Resources Inc. ("NGEx" or the "Company") (TSX: NGQ, Nasdaq Stockholm: NGQ) is pleased to announce that it has started a Preliminary Feasibility Study ("PFS") on its 100% owned Josemaría Project in San Juan Province, Argentina.

NGEx Resources Inc. (CNW Group/NGEx Resources Inc.)

The Company has retained SRK Consulting (Canada) Inc. and Ausenco Engineering Canada Inc. to complete a PFS which will evaluate the potential to develop an open pit mine and adjacent process plant to exploit the Josemaría deposit. The PFS will benefit from the extensive work already completed on the project and is expected to be finished by the first quarter of 2019. 

Josemaría is currently part of the Company's Project Constellation Preliminary Economic Assessment ("Constellation PEA") which evaluated a combined project starting with an open pit mine at Josemaría, followed by underground development of the Company's nearby Los Helados Deposit (see Constellation Technical Report for details).  The Constellation PEA demonstrates a robust, long-life project that represents one potential development scenario for the Company's projects.  It also highlighted the quality and strengths of the Josemaría deposit including:

  • A near surface supergene enrichment zone that contains an Indicated Resource of  150 million tonnes at 0.56% copper and 0.38 grams per tonnes gold for a copper equivalent2 (CuEq) grade of 0.76% (0.6% CuEq cut-off)
  • Its potential to produce an annual average of 185,000 tonnes of copper, 345,000 ounces of gold and 1.2 million ounces of silver in the first 5 years of production;
  • Straightforward metallurgy producing a high-quality copper concentrate with high gold and silver content;
  • A low strip ratio;
  • Nearby water supply from aquifers in Argentina; and
  • A well defined permitting regime and strong support for mining development  from the San Juan provincial and National authorities in Argentina

NGEx's CEO, Wojtek Wodzicki stated, "We are very excited to begin a study that we expect will highlight the full potential of the Josemaría project. We expect the study to build on earlier work and to demonstrate the potential for a straightforward, low strip, open pit operation, producing a high-quality precious metal-rich copper concentrate. It is envisioned that the mine and all associated infrastructure will be located in the mining friendly province of San Juan.  The PFS economics are expected to benefit from the recently proposed decrease in the Argentine corporate tax rate from the 35% used in the Constellation PEA to 25% starting January 1st, 2020.  Additionally, NGEx's attributable share of the net present value of the PFS project will be 100% compared to 60% of the Constellation PEA project following our buyout of our Japanese partner's interest in Josemaría in 2017.  A further important consideration is that the PFS will target mining all the Josemaría resource rather than the 37% contemplated by Project Constellation.  The quality of the existing data means that the PFS can be fast tracked and we expect to present the results of the study by early 2019.   Once the PFS is complete, we intend to move the project forward as quickly as possible towards permitting and development."

On behalf of the board

President and CEO

Notes to accompany Josemaría Mineral Resource tables



1.

The Mineral Resource estimate has an effective date of August 7, 2015.



2.

Mineral Resources are reported using a copper equivalent (CuEq) cutoff grade.  CuEq was calculated using US$3.00/lb copper, US$ 1,400/oz gold and US$23/oz Ag and was based on copper, gold and silver recoveries obtained in metallurgical testwork on four composite samples representing the rhyolite, tonalite, porphyry and supergene zones.  Copper recoveries for the rhyolite, tonalite and porphyry zones were calculated as a function of copper grade, ranging from a low of 81% to a high of 97%.  Copper recovery in the supergene zone was fixed at 85%.  Gold recoveries were fixed between 62% and 73% and silver recoveries were fixed between 53% and 75% depending on the zone.



3.

Details of the Josemaría Mineral Resource estimate are contained in the Constellation Technical Report.
