HENDERSON, Nev., Nov. 08, 2016 (GLOBE NEWSWIRE) -- Oroplata Resources, Inc. (OTCBB:ORRP) ("Oroplata" or the "Company) is pleased to announce that a surface sediment sampling program designed to test for Lithium (Li) values in playa sediments has returned significant geochemical results at the Company's Western Nevada Basin project ("WNB"), in Nevada. During the month of October the Company conducted geochemical sampling of sediment, rock and brine within and around the WNB project during the previously announced Phase One Short Field Program. Lithium had been previously located at the WNB project area from sampling by the U.S. Geological Survey (USGS). The USGS sediment samples contained highly anomalous Lithium to values in soil considered as 'ore grade' as they are above that of the producing lithium brine at Clayton Valley, Nevada.The company's program was designed to test the efficacy of employing soil sampling and the accuracy of the original sampling by using sample waypoints directly at three of the USGS sample sites as well waypoints arranged along a 5.5 mile east-west corridor with sample stations along this trajectory. A total of thirty two (32) soil samples were collected both at the near surface (1 to 5 inches) and slightly deeper using a shallow auger sample (35 to 40 inches).Samples were collected directly by Oroplata's CEO, Craig Alford, PGeo., a Qualified Person, and personally transported to the Florin Analytical Services in Reno, Nevada for preparation and analysis. Samples were screened to -80 mesh at the Florin lab in Reno, Nevada, and analyzed by 24 element ICP analysis using a four acid digestion. A duplicate set was collected for QA/QC.To date, the company has received results from 30 of the 32 soil samples and results are pending from rock and brine samples. All soil locations reported Lithium and 46% of the samples returned grades higher than 100 parts per million (ppm) Lithium, with grades up to 188 ppm from the sediment, confirming that lithium is present at the Project.Of the sites tested for direct comparison against the previous USGS sample results, the dry near surface sediment samples conformed best with the USGS samples. The newer samples confirmed 'ore grade' results for Lithium and Boron, however our results were typically 17% less than USGS samples. Laboratory methodologies may explain the slight discrepancy.Craig Alford, CEO of Oroplata Resources commented, "Confirming high lithium values at surface at the Western Nevada Basin Project is highly significant; this is a deep, massive closed basin with the potential to be Nevada's largest Lithium brine target. We are all extremely excited about moving this project forward."The company plans to carry out additional exploration programs to determine the potential for an economic lithium brine deposit. Future exploration will consist of deeper auger sampling followed by a detailed geophysical program to define drill targets.
