Octava Minerals Ltd. announced that field reconnaissance has identified the presence of a new lithium prospect at Talga, named Nimerry, located 3km to the east of the Pinnacle Well lithium prospect and ~10km northeast of the Archer Lithium Deposit (18Mt @ 1.0% Li2O). Multiple pegmatites have been identified at the Nimerry prospect which are hosted within greenstones close to the granite greenstone contact, which is an important target geology used in the discovery of lithium mineralised pegmatites in the Pilbara. These pegmatite outcrops varied in size, with the largest identified being approximately 30m in width and over 60m in length.

Early indications are that Nimerry could be similar in size to Pinnacle Well which stands at 1.5km2. The pegmatites have been sampled and sent to the laboratory for analysis, with results expected by the end of February. The company has also received assay results of the initial soil sampling program (2001 samples) and rock chip sampling (39 samples) with results confirming the large 1.5 km lithium anomaly previously identified at Pinnacle Well using pXRF Li analysis of the soil samples.

A significant number of assay results were in excess of 100ppm lithium with a maximum value of 203ppm lithium. Similar to the Pinnacle Well lithium prospect, where lithium mineralisation has been identified, Nimerry is also proximal to the Mooyella Monzogranite and other late-stage granite intrusions which are considered as the source intrusions to the lithium pegmatite mineralisation in the region. It also has similar proximity to the Moolyella Tin and Tantalum alluvial field.

As announced on 10 November 2022, multiple pegmatite targets have been identified at Talga through remote sensing work, with a number of priority areas now being targeted with field evaluation. Multiple pegmatites have now been identified in the field at Pinnacle Well and Nimerry prospects. The Talga lithium project has ~20km of granite-greenstone contact zones which are prospective for LCT (lithium ­ cesium ­ tantalum) mineralisation with new targets being added.

Octava is conducting a systematic exploration program to identify and prioritise targets for an extensive drill program to commence at the conclusion of the current wet season. With recent heavy rainfall, access to some of the lithium targets at Pinnacle Well and Nimerry was restricted. Field reconnaissance of these and other targets nearby will occur as soon as weather permits.

Results for the samples that were collected are expected by the end of February. The large lithium anomaly at the Pinnacle Well prospect identified using pXRF analysis of the initial soil samples has now been confirmed through receipt of the laboratory results. A significant number of assay results were in excess of 100ppm lithium with a maximum value of 203ppm lithium.

Considering the mobility of lithium in the weathered environment, these results are highly encouraging. Appendix 1 contains location and results of samples with Li>100ppm. The drilling program will test prospects defined by significant soil geochemistry anomalies coincident with favourable structures within targeted geology from field mapping.

Next Steps The priority at Talga is advancing towards drill-ready status, which will include the following: Awaiting laboratory analysis of rock chips from Nimerry. Field reconnaissance to investigate pegmatite extents within greenstone east of Nimerry. Finalise locations of the inaugural exploration drilling program at Pinnacle Well and Nimerry prospects.

Conduct exploration drill program to test priority lithium targets.
