Galan Lithium Limited (ASX: GLN) has identified potential new targets following a successful survey programme at the Greenbushes South Lithium project in Western Australia in which it is operating a joint venture with Lithium Australia (GLN (80%) and LIT (20%).,
UltraMag Geophysics undertook four lines and roughly five km of Deep Ground Penetrating Radar surveys in October 2021. The survey lines were undertaken perpendicular to the inferred trace of the Donnybrook-Bridgetown Shear Zone (DBSZ).
The preliminary results confirm that the method was successful in being able to penetrate to about 40 – 50 m in depth. The survey could delineate the presence of the DBSZ to depth and three potential blind pegmatites like targets at depth.
The general location of the pegmatite like targets identified by the DGPR survey corresponds to geochemical anomalies of pathfinder elements (As, Sb) in historical surface soil assays. Future surveys will follow up on these pegmatites like targets at depth.
The ongoing soil sampling programme focuses on the surface expression of the DBSZ that hosts the Greenbushes deposit.
The DBSZ is a steeply dipping, N-S trending shear zone, primarily associated with syntectonic emplacement of the lithium-bearing pegmatites of the Greenbushes mine to the north. Recognised in geophysical data, this prominent geologic feature and the recent mapping helped identify its surface expression through the Greenbushes South project.
Conservation management plans have been submitted (September 2021) to the Department of Biodiversity, Conservation and Attractions to extend our access to the DBSZ. Once approved, we will undertake further soil sampling, geophysical, and air-core drilling programs.
Managing Director Juan Pablo Vargas de la Vega said additionally, Galan is planning future high-resolution UAV magnetic surveys to identify the target boundaries’ scale and investigate if the program could incorporate other geophysical methods. Combined with the historical data, these initial surveys serve as a positive sign for future targeted soil and geophysical surveys along the DBSZ to help identify potential blind pegmatite bodies.
“These geophysical results are exciting as we continue to progress and move forward with exploration on our key tenement holdings in the area,” he said.
“Whilst the identified potential targets on our Greenbushes South JV ground certainly gives us something to smile about, there is more to do to firm up the big geological picture of the system before we can commence drilling. The new data keeps indicating that our tenements are highly prospective for lithium given their proximity to the Greenbushes mine.
“We look forward to updating the market once more data has been gathered from our new geophysics and soil sampling results.”
The Greenbushes South Lithium project is located 200 km south of Perth, with an area of 353 sq. km.
