Andrada Mining Limited announced that it has produced high-grade lithium spodumene concentrate from mineralised pegmatite material sourced from the Lithium Ridge licence area (ML133). Metallurgical test work on the two samples selected from exploration drill chips produced during reverse circulation drilling, was conducted by Geolabs Global, a South African provider of mineral processing solutions. The aim of the test was to investigate lithium mineral composition and recovery potential in an area of the Lithium Ridge licence where significant spodumene occurrence was observed during exploration.

The samples are composites of drill chips, and each sample was sourced from a different pegmatite body as illustrated on Figure 3 and Figure 5 below. The samples yielded a weighted average feed grade of 1.69% Li2O and 15.2% spodumene The samples were subjected to a standard 5-stage spodumene flotation process to assess the potential recovery steps. Initial de-sliming at 25µm and removal of the mica through flotation were followed by a spodumene rougher flotation stage and three cleaner flotation stages.

The two tests produced a weighted average concentrate grade of 6.8% Li2O or 75% spodumene, at a weighted average recovery by flotation of 76% Li2O or 80% spodumene. The full assay results are tabulated below, confirming the potential for the production of a battery-grade spodumene concentrate. The Company believes the spodumene mineralisation could also be amenable to dense medium separation ("DMS").

The fine particle size distribution of the drill chip samples made it unsuitable for DMS test work, but future sampling and test work will cater for DMS testing. Lithium Ridge (ML133) is a fully permitted mining licence located approximately 35 km southeast of the town of Uis and Andrada's operating Uis Mine. The Company completed an initial exploration drilling programme on Lithium Ridge in Third Quarter 2023.

A second phase of drilling, including mineralogical characterisation, is planned for First Quarter 2024 to increase geological confidence, prove continuity of mineralisation along strike, and to establish a maiden mineral resource estimate. In addition, the Company plans to conduct comprehensive metallurgical test work to support future feasibility studies for a mining and processing facility at Lithium Ridge.
