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.

In August 2017, Arrow Minerals commenced a maiden RC drilling programme with four mineralised pegmatites drilled. High grade lithium and tantalum was discovered with assay results including:

  • GASRC0016: 2m @ 1.71% Li2O from 118m including 1m @ 2.01% Li2O from 119m;
  • GASRC0011: 4m @ 1.42% Li2O from 0m including 1m @ 2.00% Li2O from 1m;
  • GASRC0009: 2m @ 1.49% Li2O from 106m and 7m @ 122ppm Ta2O5 from 101m; and
  • GASRC0007: 23m @ 0.98% Li2O from 0m including 5m @ 1.35% Li2O from 0m and 3m @ 1.22% Li2O from 20m.

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.
