The prospectivity of this area was confirmed by positive historical regional stream and soil sample geochemistry results, with recent infill work validating potential extensions. The lithium prospectivity is centred on a suite of mineralised pegmatites that geologically mapped to intrude and crosscut a meta-dolerite host rock. The pegmatites run parallel to each other in a north-south orientation, with the dominant lithium mineralisation being spodumene.

The company has completed four phases of mixed RC and diamond drilling programs which have generated multiple high-grade lithium intersections across six visible mineralised pegmatites and led to the discovery of an additional lithium mineralised pegmatite “WinBin” in October 2023.

Subsequent drilling of WinBin demonstrated that the thickened, deep set, lithium mineralisation defined at the deposit inflects and cojoins an extension to Pegmatite C and forms an arcuate system striking over at least 580 metres and remains open at depth.

With Prospect’s core strategy focused on the exploration and development of the Mumbezhi Copper Project in Zambia, planned exploration activities at Step Aside are currently pared back to minimum holding commitments. Excellent lithium discovery potential remains waiting to be unlocked at Step Aside with future drilling.
