Tyranna Resources Ltd. announced the results of its maiden drilling campaign at the Muvero Prospect Angola, Africa with intersections of high-grade lithium mineralisation encountered during a very short maiden drill program. Summary of Drilling Results: Drill-holes NDDH004, NDDH005 and NDDH009 intersected different parts of the same zone of lithium mineralisation, with the following results: NDDH004; from 20.25m to 43m, 22.75m @ 2.02% Li2O including 24m to 31m, 7m @ 3.06% Li2O, which contains 1m @ 5.26% Li2O from 29m - NDDH005; from 13.10m to 17.00m, 3.90m @ 0.70% Li2O and from 26.00m to 32.00m, 7m @ 1.80% Li2O NDDH009; from 10.00m to 24.00m, 14m @ 1.39% Li2O including 14.30m to 19.00m, 4.70m @ 1.95% Li2O. In addition, some very high grades of Tantalum and Tin, commodities that commonly occur with lithium minerals in many pegmatites, were attained, e.g., 1m from 18m @ 2036ppm Ta (i.e., 1m @ 0.25% Ta2O5) in NDDH009 and 1m from 17m @ 2146ppm Sn (i.e., 1m @ 0.27% SnO2) in NDDH004.

These grades suggest that zones of economically significant Tantalum mineralisation and Tin mineralisation, may be present in the Muvero pegmatite. The intersection by NDDH004 of an interval of high grades of Caesium by NDDH004 (40m - 41m, 1m @ 23,884ppm Cs, i.e., 1m @ 2.53% Cs2O) suggests that the drill-hole passed through part of a pollucite zone. This proves that pollucite is present in at least two parts of the Muvero pegmatite and may prove to be an economically significant component.

Drilling and Sampling Parameters: Nine drill-holes, NDDH001 to NDDH009 were completed (Figure 3), of which 5 drill-holes, NDDH004, NDDH005, NDDH006, NDDH007 and NDDH009, intersected pegmatite containing lithium-bearing zones. The drill-core from these drill-holes were sampled and assayed. Details of drill-hole locations and orientations and assay results are appended (Appendix 1; Collar Table, Appendix 2; Assay Results).

Quality Assurance and Quality Control strategies, including use of Blanks, Certified Reference Materials and Field Duplicates (quarter core) were implemented. Details of sampling procedures and assaying methods. Analysis of the QA/QC samples assay results confirm that the assay results for the drilling discussed in this announcement are accurate and precise.

As the Muvero pegmatite is very coarse-grained, intersections of the mineralised zone will include randomly variable proportions of lithium minerals and matrix minerals. Therefore, the mineralised zone is more accurately defined by mineral composition than merely relying upon grade cut-offs and this approach has been used in defining and reporting the mineralised intervals. Furthermore, any mineralisation contained within altered host-rock is specifically excluded.

Drilling Results Conclusions: The Muvero Prospect appears to be dominated by a single pegmatite that intruded a complex set of fractures, which resulting in the pegmatite consisting of interlinked segments of varying orientation and thickness, including distinct bulges. High-grade lithium mineralisation appears to be mainly located in thicker portions of the pegmatite, especially the bulging portions. Field observations establish that the pegmatite ascended into the fractures, i.e., the pegmatite source is below the pegmatites that outcrop.

It is not unusual for pegmatites to extend hundreds of metres below the surface, and it is likely that this applies to the Muvero Prospect also. It is also likely that there are additional bulges, and there may be a large thick source-pegmatite, containing high-grade lithium mineralisation, from which the pegmatites exposed at surface emanate. Drilling in 2022 confirmed high-quality high-grade lithium mineralisation is present at Muvero and that at least some of these high-grade zones may be much larger than their surface-expressions suggest: > Drilling in 2022 "barely scratched the surface" of Muvero > Drilling in 2022 covered only a small portion of the surface extent of Muvero > There is significant untested potential at Muvero > Testing Muvero adequately requires more drill-holes and deeper drill-holes.

Tyranna intends to complete follow-up drilling at Muvero to test its potential more thoroughly by extending coverage and ensuring greater depth of penetration of the drill-holes. Next Steps: The mineralisation intersected by NDDH004, NDDH005 and NDDH009 is very similar to the material collected in 2022 as a bulk sample for metallurgical testing. Metallurgical testing of the bulk sample is currently in-progress and results are expected in late March or early April, these results will be reported as soon as they are available.

In the meantime, Tyranna will complete fieldwork testing some remote targets within the Namibe Lithium Project and initiating access and site-works preceding the next drilling campaign. Information about this program will follow in due course. Tyranna is currently finalising the next drilling campaign which will include deeper drilling at the Muvero Prospect, along with drilling of at least 2 additional prospects.

The second drill program at Namibe will commence as soon as possible and the exploration team are fast tracking the planning due to the very maiden drill results obtained.
