San Jorge Li project

Greenwing ‘significantly’ expands brine body area San Jorge Lithium Project

Greenwing Resources (ASX:GW1) reports significant progress at the San Jorge Lithium brine project located in Argentina’s ‘prolific’ Lithium Triangle with the completion of a Transient Electromagnetic (TEM) Geophysical survey.

The project is in Catamarca Province, one of three provinces in the north of Argentina that host globally significant resources of lithium, hosted in brine beneath salars.

The TEM geophysical survey has significantly expanded the surface area underlain by a ‘highly conductive’ response, indicative of an expanded brine body.

Greenwing reports it is also negotiating a contract with an Argentine drilling company, with experience working on salars, for the company’s maiden drill program at San Jorge. Logistics planning is ongoing, with the aim to begin drilling around the end of the September quarter.

The TEM survey consisted of 10 lines with 128 TEM stations. The exploration objective of the TEM survey was to map the extent of the brine body, particularly off the salar, and to provide information on the lithologies associated with aquifers in the salar, as well as to define geological structures.

The survey successfully defined the brine body extending beneath lava flows and gravels west of the salar

The survey successfully defined the brine body extending beneath lava flows and gravels west of the salar, extending up to 2.4km west of the salar surface. Over the salar the survey defined the presence of brine to depths of 100 to 150m, the maximum resolution of the survey in the highly conductive environment of the salar.

Commenting on the works program, Chief Executive Officer Craig Lennon said: “We are extremely pleased to have completed the TEM Electrical Geophysical survey and defined the full extent of the brine target at the project.

This information will be used to finalise locations for the phase one drilling program, to confirm the range of lithium concentrations and porosity values in the project.

We look forward to commencing the maiden drilling program when the permit is approved by the Mines Department, amid the continued strong outlook for lithium long-term.”

The ‘highly prospective’ San Jorge Project covers a total of 38,800 hectares, and notably it is located within the Argentina’s Lithium Triangle which accounts for a significant portion of the world’s lithium production.

It is surrounded by major lithium mining and development companies including Allkem, Livent, Gangfeng, Zijin Mining, Rio Tinto, Lithium Americas, Lake Resources and Galan Lithium.

Greenwing is an Australian-based critical minerals exploration and development company committed to sourcing metals and minerals required for a cleaner future.

With lithium and graphite projects across Madagascar and Argentina, Greenwing plans to supply electrification markets, while researching and developing advanced materials and products.
