Mt Palmer Project
Mt Palmer is a small high-grade historical mining complex that produced over 158koz of gold at 15.9g/t. Mt Palmer was last commercially mined in 1944.
Location and Access
Mount Palmer is located around 15km east of the Marvel Loch townsite in the Shire of Yilgarn, Western Australia.
The project can be accessed from Perth by the Great Eastern Highway to Southern Cross and then by local roads via either Marvel Loch or directly from the Great Eastern Highway at Yellowdine. Within the project, access is via an all-weather gravel road and secondary tracks.
Mount Palmer is located in the central area of the Southern Cross Greenstone Belt. The Southern Cross Greenstone Belt is a strongly deformed, metamorphosed synformal remnant of a once larger greenstone assemblage. It has been shaped and attenuated by the emplacement of syn-tectonic granitoids include the Ghooli, Parker, and Rankin domes.
The historical workings at Mount Palmer are hosted within an amphibolite sequence which extends from the greenstone-granite contact located approximately 400m to the west of the mine and a thin Banded Iron Formation trending north-northeast located 200m east of the mine.
The central project area collectively covers >10km of the granite-greenstone contact. Cenozoic deposits cover most of the project area away from this contact in both directions.
History and Historical Production
The major historical workings at Mount Palmer were mined from 1934 to 1944 and in that time, over 310,000t at an average gold grade of 15.9g/t produced over 158,000oz gold.
Aurumin Work Program
The initial focus for exploration was strike extensions and assessment of parallel lodes in and around the historic mine. 32 reverse circulation (RC) holes were drilled in March 2021 – no significant results were returned from this program, however the structures were intersected where anticipated.A detailed mapping program was completed in May 2021 over the entire project area. The Company plans to undertake a detailed geochemical soil survey and prospect scale mapping later in 2021.
To date Aurumin has focused exploration within the historic mine centre, where an initial RC program was completed in March targeting strike and dip extensions. The program was successful in intersecting historically mined and new shallower parallel structures, however only subdued grades (Max <2g/t Au) were returned.
