A geological study of tenements surrounding the Livingstone gold project in Western Australia has identified a number of compelling and highly-prospective targets for owner Kingston Resources (ASX: KSN).
It has also shown the project’s existing gold deposits are likely to be part of a much larger mineral system.
The study was designed to place individual prospects in the Livingstone area into a wider geological context and enhance the company’s understanding of the relationship between mineralisation at the various deposits.
It integrated all historical spatial data on the landholding as well as new information gained during Kingston’s tenure including exploration activity in 2019 and 2020 which focused on localised areas comprising the Kingsley prospect, conceptual targets at Stanley Deeps and confirmatory drilling at the Homestead and Winja prospects.
The data was entered into a mineralisation model to identify and rank areas considered to be highly-prospective at a deposit and district scale.
Characteristics of the regional Padbury Basin and the western extension of the Bryah Sub-basin were included in the mineralisation model and contributed to the definition of targets.
The basins have been recognised as highly-prospective terrain comprising multiple gold deposits hosting more than 1 million ounces of gold each, as well as numerous prospects and mineral occurrences.
Sandfire Resources (ASX: SFR) recently launched a major exploration campaign in the Bryah Sub-basin targeting copper-gold discoveries to feed its high-grade DeGrussa project, east of Livingstone.
Exciting exploration play
Kingston managing director Andrew Corbett said the Livingstone project continues to develop as an “exciting exploration play” for Kingston.
“Our recent work has resolved a mineralisation model that has opened up the prospectivity of the entire tenement package outside of the focused exploration areas targeted by previous explorers,” he said.
“The Bryah Sub-basin, in particular, is considered to be fertile for gold and base metal mineralisation according to current mineralisation models and represents a compelling exploration target.”
Extending the project
In 2020, Kingston extended the Livingstone tenement holdings to ensure complete coverage of geological units comprising the western extension of Bryah and extensions of major regional-scale structures which host and control the district’s gold mineralisation.
The extended package encompasses approximately 13km of strike over the prospective faulted contact between the Archean Yilgarn Craton to the south and the mafic/ultramafic of the Trillbar Complex to the north.
More recently, Kingston completed a review of regional and prospect-scale surface exploration datasets, geophysical datasets and 3D drilling data to create the mineral systems model.
Mr Corbett said it aimed to bring a “whole-of-tenement perspective” to the exploration opportunity and target generation process.
