NRG Announces Excellent Pumping Well Test Results at Flagship Hombre Muerto North Lithium Project

August 9, 2018 / Vancouver, BC / NRG Metals Inc. (“NRG” or the “Company”) (TSX-V: NGZ) (OTCQB: NRGMF) (Frankfurt: OGPN) the Company is pleased to report pumping test results for the first 10 inch large-diameter pumping well at the Hombre Muerto North Lithium Project, Argentina. The well is located on the Tramo Claim portion of the project group.

This pumping well was drilled immediately adjacent to our first exploration diamond core hole following the excellent results from the recent sampling that provided assay results of 401 meters of 900 mg/L lithium with very good chemistry as reported in the Company’s press release dated June 28, 2018. Together with information from the diamond core drilling program, data from thepumping test will be used to calculate resources and reserves for the project. If warranted, this pumping well can be used for production as part of our fast-track development of the project.

NRG Metals completed a 72-hour pumping test that produced 26 liters per second of brine. The test was limited by the capacity of the pump causing our test to rapidly reach the limits of the pumping equipment and measurement devices at the site. The pumping test was designed and monitored by our independent technical consultants, Montgomery & Associates of Santiago, Chile.

Based on these positive initial pump test results, our technical team believes that the well could have significant additional pumping capability. The Company is planning to mobilize additional equipment to run a test with a higher capacity pumping system as soon as possible.

José de Castro, Chief Operating Officer of NRG Metals Inc., commented, “we are very pleased with the results of the pumping test at Hombre Muerto North. These results have removed a significant part of the risk associated with developing a lithium operation. We are seeing exceptionally high grades in clastic host rocks with good permeability, and the brine chemistry is very favorable. The Hombre Muerto North brine is unsaturated and has low sulfate and magnesium ratios. Brine with these characteristics has the potential to evaporate more quickly while using less pond area than would be the case for a typical saturated brine and will require lower consumption of chemical reagents potentially resulting in diminished capital and operating costs.”

The project is located in the province of Salta, Argentina at the northern end of the prolific Hombre Muerto Salar, adjacent to FMC’s producing Fenix mine and the Sal de Vida development stage project owned by Galaxy Resources Ltd. Galaxy recently drilled a brine pumping well on their property which is adjacent and contiguous to the south of the NRG Tramo claim. Galaxy has also announced it has entered into a letter agreement for the sale of their northern portion of the Sal de Vida project to the Korean lithium producer POSCO for US$280 million (subject to third quarter POSCO board approval). The sale includes that portion of the salar which surrounds the NRG Metals Tramo claim.
