Partial Relinquishment Report for Exploration Licence 30739 Lake Mackay Project from 13th of October 2017 to 21st October 2021

Abstract

This report summarises the partial relinquishment of tenement EL 30739 triggered by the fourth anniversary of the tenement being granted on the 13th of October 2017. IGO Limited (IGO) tenement EL 30739 is located approximately 330 km northwest of Alice Springs in the western Aileron Province of central Australia. EL 30739 forms part of the Lake Mackay Project joint venture with Prodigy Gold NL (PRX). Ownership of the project is split 70% to IGO and 30% to PRX, with each party contributing their share of the project expenditure. All on-ground exploration since the tenement was granted has been conducted by IGO, the operator of the joint venture. On relinquished ground in the reporting period 13 October 2017 to 21 October 2021, IGO completed airborne magnetic, radiometric and electromagnetic surveys, 1 ground electromagnetic survey, and obtained 166 soil samples and 1 rock chip sample. This work was part of a wider exploration program across the Lake Mackay project area. The tenement was also subject to a site heritage clearance by the Central Land Council. IGO have relinquished ground for four main reasons. There were no anomalous geophysical or geochemical targets generated from the surveys conducted, targets generated were fully tested, areas were considered unexplorable because of significant depth of cover, or areas were excluded by heritage sites. No further work is recommended on the relinquished ground.
