Second Pump Well/Potential Production Well at Hombre Muerto North

Maiden Resource Estimate Expected Shortly

VANCOUVER, Sept. 21, 2018 /CNW/ - NRG Metals Inc. ("NRG" or the "Company") (TSX-V: NGZ) (OTCQB: NRGMF) (Frankfurt: OGPN) The Company is pleased to announce the completion of a second pumping well at the Hombre Muerto North Lithium Project, Salta, Argentina. The well, designated TWW18-02, was drilled to the target depth of 400 meters, and it is located immediately adjacent to core hole TH18-02, which was described in the company's press releases dated July 10, 2018 and August 23, 2018. Pumping tests will commence shortly.

Pumping well TWW18-02 was drilled adjacent to core hole TH18-02 on the western side of the Tramo concession. The core hole was drilled to a depth of 281 meters, and the arithmetic average of single packer, double packer and one bailer sample from surface to a depth of 230.5 meters was 638 mg/L with a low Mg to Li ratio of 2.65 to one. Host rocks were mainly poorly-consolidated sandstone from surface to 77 m, followed by compact halite from 77 to 139 m, poorly-consolidated sandstone from 139 to 166 m and then intercalated halite and sandstone to the bottom of the hole. The results from the pumping well were consistent with the core hole.

As we reported in our press release dated June 28, 2018, the arithmetic average of all samples (single packer) for TH18-01 from the surface to a depth of 401 meters was 900 mg/L with a low magnesium to lithium ratio of 3.0 to one. Host rocks were almost entirely poorly-consolidated sandstone and conglomerate. Pumping well TWW18-01 was drilled adjacent to core hole TH18-01, and the results from the pumping well were consistent with the core hole. Initial pumping tests from TWW18-01 indicated an average pumping rate of 25 liters per second of brine, but the capacity of the pump was limited, and we expect that this rate will be exceeded with a larger pump. TH18-01 and TWW18-01 are located on the eastern side the Tramo concession approximately 2.1 kilometers from hole TH18-02 and TWW18-02.

Two bulk samples of brine have been collected from pumping well TH18-01 for technical evaluation. A 200 liter sample has been shipped to the Company's strategic partner Chengdu Chemphys Chemical Industry Co., Ltd, ("Chemphys"), located in Chengdu, China. Chemphys, along with Sunresin New Materials Co. Ltd. , Xi'an, located in Shaanxi, China, are evaluating  the brine for new recovery applications. A large bulk sample has also been collected via tanker truck by Alex Stewart Laboratories, located in Jujuy, Argentina, to evaluate and optimize magnesium removal.

NRG's technical advisor, Montgomery and Associates of Santiago, Chile, is preparing a maiden resource estimate compliant to National Instrument 43-101, as part of a technical report for the Hombre Muerto North project, which will be completed and announced shortly.
