NRG Metals Inc announced that assays for double packer samples collected over the interval from 300 to the bottom of the first hole at a depth of 401 m. The samples for this interval average 918 mg/L lithium with a relatively low Mg to Li ratio of 3.0 to 1.0. These values are very consistent with the assays received for the samples from surface to a depth of 300 m, and the average for the entire 400 m hole is 900 mg/L lithium with an average magnesium to lithium ratio of 3.0.


1. Brine samples collected from 300 to 401 meters show high grade values very similar to the assays previously reported for the samples from surface to a depth of 300 m, with an arithmetic average 918 mg/l lithium and a low magnesium to lithium ratio.

2. The arithmetic average lithium concentration for all of the samples from the surface to a depth of 401 m is 900 mg/l, with a relatively low magnesium to lithium ratio of 3.0 to 1.0.

3. Adjacent rotary drill hole for pump testing has been completed to a depth of 393 m and pump testing will commence shortly.

4. Drilling on a second core hole located 2.1 kilometers to the west of the first hole is advancing.

Drilling is proceeding on a second core hole located approximately 2.2 kilometers to the west of the first core hole. As of June 26, the hole had advanced to a depth of 208.0 m. Poorlyconsolidated sandstone similar to what was drilled in the first core hole was encountered to a depth of 77 m, followed by a layer of compact halite before passing back into mostly poorly-consolidated sandstone from 139 m to the bottom of the hole. Drilling is continuing, although the rate of advance has been slowed by the poorly-consolidated nature of the clastic sediments.

Mr José de Castro, Chief Operating Officer of NRG Metals Inc., commented that "We are very enthusiastic about the results at Hombre Muerto North. We are seeing exceptionally high grades in a clastic host rock that appears to have good permeability, and the brine chemistry is very favorable. The production of lithium from brine involves concentration of lithium contained in the brine by evaporation. The Hombre Muerto brine is unsaturated, which means that it should be possible to concentrate the brine more quickly using less pond area than would be the case for a typical saturated brine. Furthermore, the sulfate and magnesium ratios are low compared to other salar brines, and this means that the consumption of lime and other reagents should be relatively low compared to other lithium projects. These characteristics imply favorable operating and capital cost profiles, should the economic and technical feasibility of the project be established."

The sampling was conducted with single packer equipment over 1-m intervals, approximately every 20 meters. On site QA/QC for the sampling was directed by Cristian Avila of Montgomery and Associates of Santiago, Chile under the supervision of Mike Rosko, also of Montgomery and Associates, a Qualified Person under NI 43-101.

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 being developed by Galaxy Resources Ltd.
