The AIM-traded firm said the initial programme will focus on existing cleared drill pads at Munni Munni and high-priority copper-gold extension targets at Whundo, while a government co-funded fixed-loop electromagnetic survey is due to begin in early July to refine drill targets.
An eight-day heritage survey is also scheduled from 10 August to clear additional drill locations and access routes.
GreenTech is also progressing a resource update and metallurgical studies at Munni Munni, with results expected in August to support an updated mineral resource estimate and an initial scoping study.
Alien holds a 30% interest in the joint venture and owns about 10% of GreenTech's issued share capital.
