Lightning Minerals Ltd (ASX:L1M) is undertaking targeted infill soil sampling at its Dundas Lithium Project in Western Australia to further define lithium drill targets as it tests previously identified lithium in soil anomalism of up to 147ppm.
The company's managing director Alex Biggs said, “As much as our focus is on Brazil and our accelerated exploration on those projects, it is important that we further our efforts at Dundas also particularly as we have gained significant knowledge of the region since our works began there in 2022.
“The company now possesses lithium exploration potential in three of the strongest jurisdictions globally for the commodity which sets us up well for success as we move forward.”
Dundas soil sampling
The program at Dundas will consist of around 500 samples and is designed to infill the existing geochemistry program which was completed on a grid spacing of 400 metres by 400 metres.
A previously completed regional soil sampling program identified a number of areas of interest, particularly on Dundas North tenements E28/3027 and E28/3028 where broad lithium in soil anomalism of up to 147ppm lithium was identified across a 35 square kilometre area.
“It’s good to be getting back to our work at Dundas following a period of review. We are focusing on areas of interest that have been previously identified as containing lithium in soil anomalism,” said Biggs.
“Our work program is focused and targeted and will allow us to identify appropriate drill targets for a future exploration program.
“The infill soil sampling on our Dundas North tenements is of particular interest as it allows for us to develop higher confidence drill targets across the project areas.”
Ongoing work in Brazil
Phase 1 soil sampling is ongoing at the company’s Caraíbas project in the prolific Lithium Valley region of Minas Gerais, Brazil, to test priority targets identified during ground reconnaissance works and initial desktop studies. The company expects results to be received “imminently”.
Over the coming weeks, soil sampling works will also begin at the Esperança project, again targeting priority target areas that have already been identified in the field and through desktop analysis.
Plans are also underway to begin infill soil sampling at the target areas within the Canabrava project following last week’s announcement of strong lithium in soil anomalism up to 113ppm lithium and identification of multiple pegmatite outcrops.

LM1 says geophysics interpretation works are pending across all three project areas. The combination of ground reconnaissance, soil sampling and geophysics is critical to ensuring confident identification of targets for drilling.
