Boca Rica Lithium Project
The Boca Rica Project was identified after conducting site visits and reviews on over 100 lithium projects
within the State of Minas Gerais. This project currently consists of 3,871ha covering an area of known
Lithium-Caesium-Tantalum (LCT) pegmatite swarms that are extensive along strike and have been
observed for up to 1.7km’s. This project offers us the opportunity to make a significant lithium discovery.
A spodumene zone has been identified that is approximately 6m in true width. Two rockchip samples
were taken of strongly weathered spodumene crystals from a shallow underground adit that returned
results of 1.16 % LiO2 and 0.13% LiO2 (please refer to ASX Release 15 March 2024)

.
Strongly weathered spodumene crystals are typically low in lithium due to leaching of the lithium in the
weathering process. Spodumene crystals in this zone are up to 1m long and represent 20% of the zone.

Figure 4: OZM diamond drilling BRDH 001
Diamond drilling at the Boca Rica Project saw the first drill hole BRDH 001 being drilled to a depth of
222.62m (see figure 6). We intersected pegmatite from surface to 219.5m downhole. Site access was
prepared using an excavator. This was the first diamond hole drilled with the company owned diamond
drilling rig that has a rated depth capacity of 1,060m drilling NQ2 core.
Samples from BRDH001 have been dispatched to the SGS Geosol laboratory in Belo Horizonte, Brazil.
The Boca Rica Projects consists of 5 tenements which are under option. Details of the Term Sheets
was set out in the Company’s ASX announcement dated 15 March 2024
