Pursuit Minerals Ltd has intersected high-grade lithium brine assaying up to 809 mg/L Li from Drill Hole 3 at the Mito tenement within the Rio Grande Sur Project in Salta Province, Argentina.

The maiden Stage 1 drilling program at Mito follows advanced geophysical data reprocessing completed earlier in the year that defined high-impact drill targets across a coherent conductive system. DDH-3 was completed at a final depth of approximately 560 metres.

Extensive packer testing across the drill hole yielded representative brine samples spanning the upper sections down to depths exceeding 550 metres, providing broad vertical coverage of the lithium-bearing system. Initial laboratory assays from two tested intervals returned 298.4 mg/L lithium from approximately 156 metres, while the deeper interval at approximately 400 metres returned the 809 mg/L concentration.

"The 809mg/L lithium result from DDH-3 is an exceptional outcome for Pursuit and places this individual brine assay amongst the highest-grade lithium results reported across Argentina's major lithium brine projects. It is a standout result that demonstrates the quality and significant upside potential we continue to see at Rio Grande Sur."

"What is particularly exciting is where we are seeing this grade. The shallower packer interval at approximately 156 metres returned 298.4mg/L lithium, while the deeper interval at approximately 400 metres returned an outstanding 809mg/L lithium. That represents a 171% increase in lithium concentration between the two tested intervals and provides a compelling indication of the potential of the deeper brine system at Mito."

Pursuit Minerals has more than 20 packer samples pending laboratory analysis from DDH-3 to assess the vertical distribution and continuity of lithium concentrations through the deeper brine-bearing sequence. Following the completion of DDH-3, the drill rig has mobilised to DDH-4 to continue the exploration program.
