Arrow Minerals controls over 600km2 of exploration licences in the Gascoyne Region of Western Australia, with a 100% interest in five tenements. The project is being explored for lithium-caesium-tantalum (LCT) pegmatites. In June 2016, Arrow Minerals completed a maiden fieldwork programme, sampling three granite suites, with the Thirty Three Supersuite demonstrating fertile fractionation trends (Mg/Li and Nb/Ta ratios. The Company undertook a project-wide stream sediment sampling programme with the aim of identifying prospects with LCT pathfinder anomalism.
The pegmatites of the Malinda Lithium Project show evidence of being highly differentiated and zoned which is similar to the Tanco (Canada) and Bikita (Zimbabwe) pegmatites. The Tanco and Bikita pegmatites show considerable internal variation in minerology and chemistry, which is apparent in the Malinda Pegmatites. This style of zoned pegmatite has produced zones of high grades at both Tanco and Bikita.
