GSWA webinar series

GSWA webinar

GSWA has responded to the COVID-19 pandemic by reprioritising its 2020–21 work program, to aid economic recovery and stimulate the exploration industry. Our response includes a program of webinars to help continue to support Western Australia’s explorers.

Waukarlycarly 1 deep stratigraphic drilling

Waukarlycarly 1 deep stratigraphic drilling
Leon Normore, Senior Geologist

Friday 20 November, 11.30-12.30pm

Following on from the 872 km onshore Kidson Sub-basin seismic survey is the 2680.5 m Waukarlycarly 1 deep stratigraphic well. This stratigraphic drilling provided continuous core from 580 to 2585 m throughout the Canning Basin stratigraphy and into highly weathered pre-Canning basement rocks, before final total depth into fresh, slightly metamorphosed dolomite. Wireline logs and a vertical seismic profile have also been completed for downhole correlation of well to seismic. This project has been funded by Geoscience Australia’s Exploring for the Future initiative and the Geological Survey of Western Australia’s Exploration Incentive Scheme.

Snapshot of the EIS Co-funded drilling: Rounds 1 to 17

A snapshot of the EIS Co-funded Drilling program: Rounds 1 to 17
Dr Charlotte Hall, EIS Coordinator                          23 October 2020

After 10 years of the Western Australian Exploration Incentive Scheme Co-funded Drilling program, a short-term study has provided a snapshot of the statistics, results and impact of the program.

From Round 1 in 2009 to June 2019 when Round 19 projects completed drilling, 482 projects had been drilled across the State. Over 8767 drillholes, for a total of 847 km, are now supplying additional geological knowledge to de-risk exploration targeting and assist research. Diamond holes stored in a state core library number 677 and 43% of these holes, regardless of hole length, have been sampled by researchers providing an important add-on value. Thirty-five projects are reported as a reflection of the ‘success’ of the co-funding with several projects now operating, or in mine planning and feasibility stages.

GSWA's 20/21 Accelerated Geoscience Program
Jeff Haworth, Executive Director                         2 October 2020

The advent of the COVID-19 pandemic has meant travel restrictions and a subsequent negative impact on exploration in Western Australia. The Geological Survey of Western Australia (GSWA) has therefore had to rethink its program for the 2020–21 financial year, to provide data and information quickly to enable the exploration industry to recover.

A recent Association of Mining and Exploration Companies (AMEC) report showed 72% of explorers had no investment and half the METS Engineering Group (METS) companies had ceased exploration operations. In addition to this, share prices for over half these companies has dropped 25–50%. The GSWA Accelerated Geoscience program will get information quickly to explorers to use and incentivise the METS sector. An increase of $5 million to the Exploration Incentive Scheme for geophysics acquisition will further stimulate the co-funded drilling program. The program will assist the critical minerals sector.

Seismic monitoring in the Wheatbelt

Seismic monitoring in the Wheatbelt
Dr Ruth Murdie, Senior 3D Geophysicist                         25 September 2020

Southwest Australia has the highest level of seismicity in the whole of the continent, yet this is not an area where, geologically, we would expect earthquakes. GSWA is installing three new seismic monitoring stations in and around the Wheatbelt in order to better locate the numerous small earthquakes that happen on a regular basis.

Permanent seismic stations operated by Geoscience Australia automatically locate some of the larger of these events, but the sparsity of the national monitoring network means that the locations obtained are very poor. These new stations double the number in the region and should result in better locations, better identification of potential fault lines and seismic hazard.

Au-Cu mineralization

Au–Cu mineralization at Obelisk, northern Paterson Orogen
Dr Paul Duuring, Senior Geologist                         4 September 2020

A project update for a collaborative study with industry that examines the style and controls on Au-Cu mineralization at the Obelisk deposit in the northern Paterson Orogen.
