Lake Mackay Project

ABM holds approximately 8000 square kilometres of exploration licenses and exploration license applications in the area to the east of Lake Mackay in the Northern Territory. The projects are located approximately 400 kilometres west of Alice Springs and are accessible by road. This project area is one of the most remote and underexplored regions of Australia.

Location Map of the Lake Mackay Project Area in the Northern Territory

The Lake Mackay project areas consist of Proterozoic sediments and intrusions and have only had a minor amount of previous exploration work consisting of widely spaced shallow drilling and surface reconnaissance along with aeromagnetic and gravity geophysical surveys. Previous work identified large metal anomalies including gold and copper as well as other pathfinder elements such as bismuth, arsenic, antimony and cobalt. The Tekapo prospect in-particular is associated with iron oxide (hematite) gossanous breccia at the surface which along with the broad suite of anomalous metals suggests an Iron Oxide Copper-Gold (IOCG) mineralisation model analogous to Olympic Dam and Prominent Hill in South Australia, the Tennant Creek systems in the Northern Territory and Ernest Henry in Queensland.

The Company has completed a 16 hole, 5,700 metre drilling program at the Lake Mackay iron-oxide copper gold project to test four targets; Tekapo 1 and 2, Manapouri and Te Anau. ABM’s programs will follow up on previous work and will perform the first ever tests of fresh-rock beneath the regolith on selected targets as noted above.

The Dodger prospect has an extensive intrusive-related gold system with large 6km by 8km underlying intrusion. The regolith (RAB) anomaly is greater than 2.5km long averaging 250ppb gold. There is minimal outcrop, however, surface channel sampling on small ridge with zones up to 4m @ 3.56g/t gold and rock chips up to 10.60g/t gold and 12% lead. 

There are five adjacent geophysical targets currently untested with surface or drill methods. ABM have four Diamond / RC holes planned and further extensional testing of regolith chemistry.

The Taupo prospect displays an anomalous corridor 8km by 1km defined by surface lag sampling and shallow RAB drilling.
