Final Report For Exploration Licence 30739 Lake Mackay Project From 13th of October 2017 to 23rd of September 2022

Abstract

This report covers exploration activities completed on the remaining ground in surrendered tenement EL 30739 over the life of the tenure (13/10/2017 to 23/09/2022). EL 30739 comprised part of Group Report GR485. Tenement EL 30739 is located approximately 330 km northwest of Alice Springs in the western Aileron Province of central Australia. Tenement EL 30739 forms part of the Lake Mackay joint venture between IGO Limited (IGO) and Prodigy Gold NL (PRX). Since May 2022, ownership of the Lake Mackay project has been split 70:30. IGO hold the majority share of tenements (including EL 30739) with potential for base metal mineralisation, and PRX hold the majority share of tenements with potential for gold mineralisation. Previously portions of EL 30739 were partially relinquished in 2019 and 2021. This report covers exploration work completed by IGO and PRX between 13/10/2017 and 23/09/2022 on the remaining ground surrendered in September 2022. Surface geochemistry work comprised 48 reconnaissance BLEG soil samples. Geophysical activities included airborne magnetic, radiometric, and electromagnetic surveys, and 1 ground electromagnetic survey (9 stations total). Tenement EL 30739 was subject to a site heritage clearance by the Central Land Council (CLC). Temporary tracks were also constructed for drilling access into historical tenements EL 30733 and EL 30740. All this work was part of wider exploration across the Lake Mackay project area. Tenement EL 30739 has been voluntarily surrendered for four main reasons. Targets generated from geophysical or geochemical surveys were fully tested, elsewhere no anomalous targets were generated, areas were considered unexplorable because of significant depth of cover, or areas were excluded from exploration by heritage sites. No further work is recommended on the surrendered ground.
