Zn, Cu skarn mineralisation in NE QLD tied to younger magmas

New UQ-GSQ research on the Mt Garnet skarn deposit (where Kagara Zinc delineated 4 Mt @ 6% Zn and 0.34% Cu) has tied Zn mineralisation to the youngest member of the Kennedy Igneous Association (KIA) – the Claret Creek Supersuite at 300 – 272 Ma. Previously, the oldest KIA supersuite (O’Briens Creek at 335 to 317 Ma) was thought to the magmatic driver of most of the complex mineralisation in the region. The new findings could open up a new search space for zinc skarns along the Chillagoe Formation. The study combined garnet geochemistry with the first direct geochronology on hydrothermal minerals in the region. The study suggested no change in the view that Sn-W mineralisation is associated with the O’Briens Creek Supersuite.

New indicators for sanukitoid gold followers in the Yilgarn

Researchers at the Centre for Exploration Targeting have a new paper with ideas for discovery of multi-million-ounce sanukitoid gold deposits in the Yilgarn, based on a detailed study of the 2 Moz Karari-Whirling Dervish deposit. The unusual deposit is related to an intrusion of syenite — an extremely alkalic magma — that puts it in the category of Yilgarn sanukitoid gold deposits, along with the much bigger Wallaby deposit owned by Gold Fields. The new paper describes a number of geochemical and mineral fertility indicators. 

Graphite prospectivity report in SA

The Geological Survey of South has released a prospectivity report on graphite, noting that SA actually has two-thirds of Australia’s known resources. No surprise to see a focus on the eastern Eyre Peninsula, but the report also notes discoveries in the Mt Woods Inlier as recently as 2017, and discusses the under-explored graphite potential of the Curnamona Region, where Havilah Resources made a significant discovery in January.

New lithium data across national catchments

Lithium explorers have a whole new national dataset to work with. GA released on 13 February acid digest results for Li, Be, Cs and Rb for the 1,315 top outlet samples in the National Geochemical Survey of Australia. NGSA previously excluded Li because a lithium-borate flux was part of the element analysis method deployed for NGSA.

Paleovalley maps in western Gawler

Paleovalleys anywhere near the uranium-rich Gawler Craton are hot property at the moment, so there will be interest in a Geological Survey of South Australia report released in December. GSSA has used its very high quality new datasets acquired for the Gawler Challenge Phase 2 project to remap vast paleovalley systems in the cental western Gawler Craton.

Pedirka gravity and reprocessed seismic

NTGS has released a major ground gravity dataset in the Pedirka Basin in the southeast of the Northern Territory. Gravity data was collected from 11,000 stations at 2km and 4 km spacings over 61,000 sq.km. The Pedirka Basin is traditionally a petroleum hunting ground but the new gravity (preliminary) dataset includes basement around the basin margins and could contain interesting features for mineral explorers. Other relevant news is the Geoscience Australia release in November of reprocessed seismic in the Pedirka Basin as part of an integrated set of seismic profiles across central Australian basins.
