The Mt. Holland project is focused on the exploitation of the resource in the Earl Grey pegmatite group. The Earl Grey pegmatite group consists of a main tabular pegmatite body flanked by numerous narrower hanging wall and footwall apophyses. The pegmatite has a strike length of at least 1 km, and a dip extent of over 2 kilometers and a thickness of up to 100 meters.

Deposit Types and Mineralization
The Earl Grey pegmatite group consists of a simple albite-quartz-microcline-spodumene petalite dominated assemblage with minor biotite, muscovite, and tourmaline (Covalent, 2020). The lithium aluminosilicates spodumene and petalite are by far the most abundant lithium-bearing minerals in the Earl Grey pegmatite; however, a wide array of trace lithium phases has also been documented in distinct domains. These are mostly late-stage alteration related phases, and except for cookeite, are a rare occurrence. Textures range from extremely coarse pegmatite through to finer grained seriate granitic to aplitic and late-stage replacement textures. The Earl Grey pegmatite group does not display the strong concentric mineralogical zonation commonly associated with complex rare element pegmatites.

Bedrock Geology
The Earl Grey pegmatite is hosted within the north-south trending amphibolite facies volcano sedimentary stratigraphy of the mideastern ultramafic belt. The stratigraphic succession broadly progresses up-dip towards the west, although potential repeti ........

Mining of the Earl Grey Deposit at Mount Holland will utilize conventional open pit mining methods. The mine plan gives a Life of Mine of approximately 50 years at a production rate of around 2 Mt/year of ore, with a total material movement 511 Mt (including waste material). The operation will be serviced by contractor-owned and operated drill & blast, as well as load & haul equipment. Mining equipment will include excavators, haul trucks, drilling rigs and ancillary equipment including dozers, water trucks, service trucks and graders.

Material movement initiated in February 2022 by removal and stockpiling of topsoil, followed by pre-stripping of waste to provide access to the first ore.

The deposit geometry presents relatively large bulk areas of both ore and waste; however, the ore/waste contact is designed to be mined as cleanly as possible to prevent ore loss and dilution of the ore with the high Fe2O3 waste. It is anticipated that precision drill and blast techniques will be employed on these ore/waste contacts, with dozers cutting to visual ore/waste contacts. Based on ore grade, excavated material will be hauled from the pit to specific locations, as follows:
· Ore which meets or surpasses the Li2O cutoff grade (high-grade ore) will be hauled to the ROM pad.
· Ore below the Li2O grade blending specifications, will be moved to the low-grade ore stockpile.
· Mixed material, derived from the ore/waste contact zone will be stored at ........
