Pocitos 7 DDH1 Intercepts +30m Brine Aquifer, Salta, Argentina

C29 Metals Limited (C29 or the Company) is pleased to advise that drilling at Pocitos 7, Pocitos salar in the province of Salta, Argentina has concluded at 420m with a packer test intercepting a deep aquifer from 370-400m. A flow test was conducted through a 49mm pipe with a submersible pump and achieved a pumping rate in excess of 2,000L an hour.


  • Maiden hole at Pocitos 7 intercepts +30m brine aquifer zone at 370m
  • Drill Hole pumped at 2,000 litres per hour with 49mm pipe
  • Samples taken for assay and testing with Ekosolve™ DLE technology
  • Planning underway for DDH 2 with a view to a mineral resource estimate
Brine samples were obtained over a three hour pumping period. Separate sample lots were sent to SGS and Alex Stewart laboratories in Salta for assay with blanks and standards, and a sample was sent to the University of Melbourne for testing using the Ekosolve™ direct lithium extraction process that the Company has licenced. Laboratory assay results are expected in 7 to 14 days.

A second hole is being planned and may be supplemented with an audio telluric (CSAMT) geophysics survey that will penetrate down to 500m to ensure that DDH2 at Pocitos 7 is optimally located.

Mr Phillip Thomas, technical consultant to the Company for Pocitos 7, reported that the core transitioned from fine clays to a combination of halite and sands at the 350m mark and became coarser and more porous as the hole approached 400m with interbedding evident.

Director Jeremy King commented:

“We are extremely pleased to intercept brines and have hit a 30m plus aquifer zone at Pocitos 7 and have such a healthy pump rate particularly given the size of the pipe and pump utilised. The team are currently conducting SG measurements on the brine and we await the laboratory analysis to determine lithium content. Subject to those results, we intend to continue our exploration program with a view to rapidly establishing a mineral resource estimate at Pocitos 7.”
