Geoscience Australia EFTF collaboration
Geologists wearing bright orange working together on materials out in bushland

The Delamerian Project collaboration between Geoscience Australia (GA) and the GSV is part of the Exploring for the Future (EFTF) program. Work continued during February with geologists undertaking field work across western Victoria. Rock samples from a range of different mineral systems were collected for geochemical and geochronological analysis.

A further four days were spent investigating and sampling core from the GSV drill core library in Werribee.

The project forms the Delamerian component of the Darling-Curnamona-Delamerian Project, which will deliver new data and knowledge to assess mineral and groundwater potential and support water management across western New South Wales, Victoria, eastern South Australia and northwest Tasmania.

The mineral exploration industry has been highly supportive of the project and has provided access to samples from their own drilling programs, including mineralised portions of drill holes.

The field work collaboration follows on from the GA deep-crustal seismic and ground gravity acquisition across Western Victoria in 2022 and a 20 km spaced airborne electromagnetic survey in 2021.

A 5 km spaced airborne electromagnetic infill survey was flown by GA in 2022. This data has recently been released by GA. The Western Victorian dataset is available on the GSV Catalogue.

Data collaboration leads to more value for Victoria

An airborne gravity survey is underway across eastern and northern Victoria to help improve GPS positioning accuracy and the understanding of the state’s geology.

Flying over southeast Victoria throughout 2023, the airborne survey is a collaboration between the Surveyor-General Victoria, the GSV and GA.

The survey will deliver consistent and evenly distributed gravity measurements, which will significantly improve Victoria’s gravity model and the accuracy of real-world heights from GPS positioning. It will also be used by geoscientists to further understand southeast Australia’s geological "architecture" and how it has evolved over time.

More detail about the survey is available from the Surveyor-General Victoria.

Historical Goldfields mapping available on GeoVic

Gold enthusiasts will be pleased to learn that historical goldfields geology maps are the latest offering available on GeoVic, the Earth Resources spatial mapping tool. The Goldfields Maps collection now contains 81 maps that date from the 1800s to the 1900s and are centred on various Victorian goldfields at a range of scales from 1:6,000 to 1:63,000.

The GSV collection of georeferenced historical mapping is continuously being updated and can be accessed via the Geology folder in the GeoVic data layers table of contents.

High resolution pdfs of historical maps are also available for download on the GSV Catalogue (formerly known as Search Assistant).

Access GeoVic and the GSV Catalogue.

Handy hint!

Use the “Add Layers” button, to bring up the “Data Layers to Add” popup menu, then navigate to the Geology>GSV Map Indexes folder turning on the “Goldfields Maps” layer, to see what georeferenced maps are available, then navigate to the Geology>Images>Historical Maps (Georeferenced)>Goldfields folder to find and turn on the desired georeferenced historical map.

Make the “Goldfields Maps” layer active and then use the Identify tool on the map area of interest and click on the Search Assistant (Reference Link) to quickly access the high-resolution pdf and georeferenced image in the Geological Survey of Victoria Catalogue.

Industry activity

Each year the Earth Resources Regulator presents a compilation of data as reported by tenement holders. 

The latest report covers FY 2021-2022, providing the public, industry investors and existing resource operators a sector-wide snapshot of activity and performance of the earth resources sector. 

It combines information from the petroleum, geothermal, minerals and extractive industries and provides detailed data on earth resources exploration, production, expenditure and licensing activities.

Access current and previous Earth Resources Regulation Statistical Reports.

Industry events

The Prospectors and Developers Association of Canada (PDAC) conference took place in Toronto from 5-8 March, drawing representation from mining and METS companies, industry experts and government agencies across the world. PDAC is a leading voice in the mineral exploration and development community, with its work centring on supporting a competitive, responsible, and sustainable mineral sector.

The event welcomed almost 25,000 attendees, over 1100 exhibitors and 2500 investors, including the Geological Survey of Victoria which attended alongside its state counterparts as part of an Australia Minerals presence.

GSV took the opportunity to promote Victoria’s gold activity and new mineral development opportunities and the role its critical minerals can play in the global transition to net zero.

Further information can be found on the PDAC website.

Victorian Gold Mining and Exploration Forum

The Victorian Gold Mining and Exploration Forum was held from 22-23 February in Melbourne, bringing together geologists and heads of industry to examine the latest developments in gold mining and exploration in Victoria.

Senior Geologist Ross Cayley presented the GSV’s latest findings from mapping and deep seismic reflection data and outlined opportunities for minerals exploration across the Melbourne geological zone. The GSV has identified, for the first time, an extended fault system that could indicate the presence of minerals in areas that have not yet seen successful exploration. A mineralisation pathway may run from close to the surface to as far down as 35-40km.

Studies of the Southern Lachlan Crustal Transect point to the mineralisation pathways reaching the surface in the vicinity of the historic goldfields Woods Point-Walhalla area, meaning faults buried under younger rock cover away from the historic goldfields could present new opportunities. GSV aims to give industry sufficient confidence to start testing these ideas.

Melbourne Mining Club luncheon

The Melbourne Mining Club (MMC) launched its first of six 2023 luncheons on 9 February, hosting keynote speaker Dale Henderson, MD & CEO from Pilbara Minerals in a packed Melbourne Town Hall.

The luncheons offer the opportunity for the resources industry to gather and hear from some of the biggest names in the mining sector.

Acess Dale’s presentation, The Australian Lithium Industry – Just Getting Started.

Cutting Edge

The 2023 Cutting Edge bi-monthly series kicked off on 7 March with the audience hearing from presenters representing Cobalt Blue Holdings, Kalamazoo and Rumble Resources.

Cutting Edge events are run by the Melbourne Mining Club and provide a forum for small to mid-cap exploration and development companies to showcase their activities, management and business strategies in an informal gathering. They are committed to fostering and promoting innovation across the sector, from exploration to processing and mining technologies.

Access the Cutting Edge presentation from 7 March.
