LSA ... a bit wary of how they have presented their EM results (the only thing I have looked at). They have mislabeled figures, and left in EW/NS artifacts that look like fence/power lines. Main concern is they only show an early time image, which is sensitive to the shallow. This is likely weathered laterite/saprolite (can host minerals, but usually low grade and can also have saline aquifers). Would prefer to see late time response that averages vertically over more of the ground (thus more sensitive to deeper sulphides) and has been processed to account for non-prospective shallow conductors.

Segue to PUR, as they have shallow conductors in some of their areas. Remains to be seen how strong/widespread the surface conductivity is and what else can be identified after processing. Deeper targets could be obscured or hard to detect if the surface conductors are too strong. Wubin tenements are in close proximity to the saline Lake Goorly, and I suspect there are drainage/groundwater issues. This is an interesting read (both in general, and it happens to be near Calingiri West): https://www.water.wa.gov.au/__data/assets/pdf_file/0016/1582/13873.pdf
