Seventh Annual Report GR461 - Exploration Licences EL 25566 and 31383 for the period 23 August 2022 to 22 August 2023

Abstract

Gempart's Musgraves Project is located in the Musgraves Province in the extreme southwest corner of the Northern Territory. Tenement comprised four granted titles EL 25566, EL 27912, EL 27913 and EL 31383 with group reporting status GR461. EL 27912 and EL 27913 were surrendered in July 2019. This document reports on exploration undertaken in the sixth year of tenure for EL 25566 and EL 31383. Primary commodities sought are gold, base metals, nickel, PGE's, and REE's. Little modern exploration data exists from government information or past explorers. There are no prospects, mineral occurrences or drillholes within the relinquished area. The geology appears to be predominantly granitoid rocks of the Mesoproterozoic Umutju Granite Suite. Work since grant has included an external exploration potential review, two VTEM surveys for total 732 line km, three ground gravity surveys for total 1,731 stations, a helicopterborne magnetic-radiometric survey for total 4,700 line km, and two field trips with 130 pXRF readings. Subsequent to ongoing data review, ground checking and two rounds of relinquishment, three prospects remain for ground EM follow-up. The prospects are two coincident gravity/magnetic anomalies, called Mag Anomaly #1 and SGC prospects, and a VTEM anomaly called VTEM Anomaly 1400a prospect. An Agreement for ground EM surveys at all prospects was concluded in March 2021; after substantial delays the contractors mobilised and completed the surveys in November 2022. The surveys collectively comprised of 136 receiver sites for a total of 8.8 km of moving loop data and 552 receiver sites for a total of 25.35 km of fixed-loop data. The EM data at all sites included noise and IP effects. However sufficient information was obtained to allow interpretation of conductors at all prospects. At Mag Anomaly #1 prospect conductive bodies were identified coincident or near-coincident with gravity/magnetic models from ground gravity and aeromagnetics. At SGC prospect very weak conductors were interpreted near gravity and magnetic models derived from a seven milliGal gravity anomaly and aeromagnetics. At VTEM Anomaly 1400a prospect anomalies recorded on 500m linespaced VTEM traverses were confirmed in the ground data. The ground EM has upgraded the prospectivity of all three prospects. The next phase of exploration is sub-surface sampling, and traverses of air-core drilling have been planned to obtain bedrock samples for geochemical assay.
