Resource and Reserve
JORC Mineral Resource and Ore Reserves
The geology of the greater Arcadia area is dominated by greenstone lithologies of the Arcturus formation of the Harare Greenstone Belt (HGB). These greenstones are encircled and intruded by a variable suite of granitic rocks, the oldest of which may have been coeval with the youngest felsic volcanic rocks of the belt. There is also some evidence for a small remnant area of gneissic basement to the greenstone belt.
Arcadia is a high grade, large tonnage deposit consisting of series of stacked mineralised pegmatites extends for over 3 km of strike length, while surface mapping and trenching has shown the total strike length to be almost 4.5 km, with definite further potential to delineate additional resources along strike and with the possibility of discovery of additional parallel ore bodies.
As of October 2021, the JORC compliant Mineral Resource estimates for the Arcadia Lithium Project were:
