La Antigua (La Rioja Province)
Argentina

TP Energy was recently successful in submitting applications in the name of its subsidiary Trans Pacific Minerales for the 211,300 hectares La Antigua project in La Rioja. La Antigua is a low altitude project, close to infrastructure, power and roads at a similar elevation to the town of La Rioja. It is 135km east of La Rioja via sealed and gravel road to La Antigua community through farm and community dirt tracks. La Antigua’s lithium prospects derive from fault-based aquifers and drainage from the Colorado River.

Recent sampling at La Antigua has shown relatively good lithium content from 519 ppm to 536 ppm lithium and low magnesium content, giving a very low magnesium to lithium ratio (1,870 ppm to 1,790 ppm Mg). Substantial drilling and exploration works were carried out by the State Hydrocarbons Company in 1991-1995, including holes with a depth up to 150m.

Further holes will be drilled at La Antigua for sampling to test the lithium bearing brine and verify previous high lithium results and low impurities. Magnetic and gravity surveys will also commence alongside the drilling with the work expected to begin in 2019.

TP Energy contracted independent geological consultants Geos Mining to conduct four separate ground surveys on the La Antigua project which indicate potential for economically viable concentrations of lithium. Testing showed that lithium levels are within industry standards and highly anomalous compared to ordinary background levels of lithium found in fresh and sea water. Salar La Antigua is TP Energy’s largest Lithium Brine holding in Argentina. At approximately 211,300 hectares or 2,113 square kilometres, the project has the potential to host multiple lithium brine bearing systems. Geological reports from Geos Mining have directed TP Energy’s work on this project to date and the company is now planning the next phase of exploration.
