Abstract

<div><strong>Output type: </strong>Exploring for the Future Extended Abstract</div><div><br></div><div><strong>Short abstract: </strong>Western Tasmania is a rich mineral province that hosts Cambrian VHMS and Devonian granite-related Sn-W systems in the Dundas Element. By comparison, the Rocky Cape region of northwest Tasmania has not been extensively explored for mineral deposits. New U-Pb monazite geochronology and galena Pb isotope data were collected from several sediment-hosted, vein style Cu-Co-Pb-Zn prospects in the Rocky Cape Element of northwest Tasmania. The identification of REE and cobaltite in some samples indicates the potential for critical minerals in this region. This is the first identification of a mineralizing system of Mesoproterozoic age in Tasmania, approximately 800 million years older than the well-known Cambrian mineralisation events in western Tasmania. These data indicate that mineralization formed during the Mesoproterozoic, broadly contemporaneous with the deposition of the Rocky Cape Group.&nbsp;</div><div><br></div><div><strong>Citation: </strong>Armistead S.E., Meffre S., Bottril R.S., Cross A. &amp; Huston D., 2024.
