MinRex Resources Limited announced the preliminary geological data from the completed RC drill program over the Sisters Lithium Project in the East Pilbara of WA. In conjunction, 3 rock chip samples were taken over newly identified pegmatites away from the firstly discovered spodumene rich pegmatites in the south-eastern portion of the E45/5871. These new identified highly anomalous lithium pegmatites have demonstrated more potential for pegmatites discoveries on the ground.

The extensive floodplain covering the area has the potential to yield further untested pegmatites. The Sisters Project is situated 1.75km east of Global Lithium Ltd. (GL1; ASX) Archer Lithium Deposit, which hosts 10.5Mt at 1.0% Li2O. The project hosts the same greenstone belt as the Archer Deposit.

Extensive pegmatites were delineated within granite-greenstone "goldilocks zone ". These zones are typical of all major lithium deposits in the Pilbara region of Western Australia. Two zones of spodumene rich pegmatites were located in the southern zone of E45/5871 striking in a north-south direction with the greenstone lithology.

This lithium rich zone is approximately 500m in length by 250m in width. On the 2 August 2022, the Company announced the high-grade rock chip sample results, which yielded 3.42% Li2O, 1.59% Li, 105 ppm Cs, 80 ppm Ta, 120 ppm Nb, 130 ppm Sn, 1,980 ppm Rb from the stacked pegmatites. Drilling has concentrated around the newly identified lithium-rich pegmatites.

The drill program comprised 15 RC drill holes, totalling 2,355m to test the outcropping pegmatites identified from the initial rock chip sampling program reported in August and September 2022. All samples have been dispatched to Nagrom Laboratories in Perth in early October and will be assayed for all the battery elements. All drill holes were collared within the Homeward Bound Granite with pegmatites intersected consisting of feldspar-minor mica-weakly altered epidote with traces of garnet in part.

The drill assays will be announced to the market once received from Nagrom Laboratories. Also, during the month of September 2022, the Company's geologist conducted a 3-day ground mapping and rock chip sampling program over the southern portion of the Sister's Project. The aim of the reconnaissance survey was to follow-up on the historic elevated lithium soil anomalies areas.

Based on the geological reconnaissance, it was concluded the anomalous lithium bearing soils were derived from lithium leaching out from the proximal outcropping pegmatites. Limited samples were collected as the pegmatites are located within an extensive floodplain area with most of the pegmatite's outcrops are concealed by alluvial sediments.
