1. Mohanga Lithium-Tantalum Project/Central Tanzania (Liontown 100%)
The Mohanga Project is located in central Tanzania approximately 40km NNE of the capital Dodoma and 400km WNW of Dar es Salaam (see Figure 1) within the south eastern part of the Tanzanian Craton. The regional geological setting is similar to the world class Greenbushes lithium deposit located in southwest Western Australia. Liontown has secured a contiguous 177km2 area where sampling of historic workings has recorded high grade lithium and tantalum values hosted by pegmatites.
During the Quarter, Liontown secured the Mohanga Lithium-Tantalum Project through a combination of tenement acquisitions and an Option Agreement with a local company. Further details of the land status are provided below.
A number of lithium-bearing pegmatites have been recorded by historic government mapping and reconnaissance rock chip sampling by Liontown geologists (Appendix 1) returned multiple significant lithium (>1%Li2O)and tantalum (>0.05% Ta2O5)values
Better results from Liontown's reconnaissance sampling include:
Sample 132428 2.95% Li2O and 0.12%Ta2O5
Sample 132432 3.79% Li2O and 0.11%Ta2O5
Sample 132436 2.76% Li2O and 0.11%Ta2O5
Sample 132439 5.15% Li2O and 0.07%Ta2O5
(See Appendix 1 for full listing of rock chip assays received by Liontown)
There has been no drilling or other modern exploration within the Mohanga Project area.
The Project is in the south eastern part of the Archaean Tanzanian Craton where it comprises a WNW-NW trending sequence of metasediments (quartzite, quartz-feldspar schist and graphitic schist), amphibolite schist and quartz-feldspar gneiss intruded by granite (Figure 2). The geological setting is considered analogous to the Greenbushes lithium deposit in southwest Western Australia, the world's largest pegmatite-hosted deposit.
Immediately subsequent to the Project acquisition, Liontown undertook first pass geological mapping, rock chip sampling and limited trenching at a number of prospects. This work confirmed a large pegmatite field within the Mohanga Project with a total of 78 pegmatites identified at 6 prospects (Figure 2).

Widths of up to 100m and strike lengths of up to 700m have been interpreted for individual pegmatites; however, further geological mapping is required to confirm dimensions. Summary statistics from the completed mapping are tabled below:

Trenches have been channel sampled with intervals based on geological logging.
Assays for the rock chip and channel sampling are expected in late January. Further work will be planned once these are received.
Comparison of Alkali Ratios
Alkali ratios (K, Cs, Rb) from whole rock geochemical analyses of the initial reconnaissance samples from the Mohanga region indicate highly fractionated pegmatites which are more likely to contain incompatible elements such as lithium and tantalum (see Figure 3). In addition, historical reports from the Greenbushes and Pilgangoora lithium deposits in Western Australia show that the alkali ratios from several areas in the Mohanga region compare favourably.
The alkali data also indicate more than one type of pegmatite with not all being prospective for lithium and tantalum. Further whole rock analyses will be completed on the recently collected samples to prioritise those pegmatites which are considered more prospective.
