Bubalus’ Yinnietharra Lithium Project is located in the Gascoyne region of Western Australia (figure 1) and situated only 2km’s east of the Malinda Prospect owned by Delta Lithium Limited (ASX:DLI) (figure 2). Drilling at Malinda by Delta has identified spodumene hosted lithium mineralisation over a distance of 1.6 km and to a depth of 350m.

There’s been no historical drilling for lithium on the Yinnietharra Project which presents a compelling discovery opportunity. Sodumene bearing pegmatites identified by Delta Lithium¹ strike in an east-west orientation, trending in the direction of Bubalus’ Yinnietharra Project boundary, representing an obvious walk up target for initial activities.

Bubalus recently (refer ASX announcement 28/02/24) completed a systematic, project wide soil sampling program with the aim to identify the size and scale of potential pegmatites within the Yinnietharra tenement boundary, given that these are unlikely to outcrop, and refine additional areas or anomalism for drill testing.

Surface sampling was conducted at a spacing of 200m by 200m across the majority of the project area, with the high priority Malinda East area adjacent to the Malinda Prospect sampled at a spacing of 100m by 100m. The anomalism at Malinda East measures 800m north-south and 450m east-west (the strike direction of the Malinda pegmatites drilled by Delta). The anomaly is defined by lithium-in-soil values above 40ppm Li and caesium-in-soils above 8ppm Cs (Figures 2 and 3). The bedrock lithologies in this area are interpreted to belong to the Leake Springs Metamorphic unit, the host rock for the mineralised pegmatites at Malinda.

Given the intense weathering profile of the regolith in the Yinnietharra region, the tenor of these anomalies are relatively subdued however they provide clear targets to focus 2024 exploration at Yinnietharra.

Bubalus continues to progress activities towards a maiden drill program in the first half of CY 2024.
