Reedy Lagoon and CSIRO eye alternative resource estimate methodology

Reedy Lagoon Corp says it is working with Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) to investigate and trial new ways to determine resource estimates that can rely more on geophysics than solely drill hole information.

The ASX-listed explorer has engaged with CSIRO to develop a method of determining magnetite resources using petrophysically-constrained magnetic modelling. The testbed for the research will be Reedy Lagoon’s Burracoppin iron project, in Western Australia, which, the company says, is progressing towards producing green high purity pig iron (HPPI).

The collaboration with CSIRO will use previously drilled core to determine the physical properties (eg magnetisation and density) of the Burracoppin magnetite deposit, and use those results to constrain a detailed 3D magnetic/density model of the mineralisation, Reedy Lagoon said.

Dr Jim Austin, CSIRO Project Leader and Petrophysics Expert, said: “Magnetite resources are unlike any other metal in that the quantity of the resource present (ie iron) has a linear relationship with both density and magnetisation. This means the total iron resource can theoretically be determined to relatively high precision using geophysical methods alone.”

The Burracoppin iron project is seeking to establish an indicated resource of 20-30 Mt of iron concentrate product within the Burracoppin magnetite deposit so that financial projections for the HPPI production can be determined. The deposit is currently identified in detailed airborne magnetic data and three drill holes.

The planned resource definition work is focused in the region between the three drill holes where, as part of the work in establishing a mineral resource, an exploration target has been determined.

“If shown to be successful, the work with CSIRO may lead to a new method of estimating a resource to JORC standards with far less drilling than is currently required, saving much expense and reducing ground disturbance,” Reedy Lagoon said.

The project was made possible through CSIRO Kick-Start, an initiative that provides funding and support for innovative Australian start-ups and small businesses to access CSIRO’s research expertise and capabilities.

SensOre and CSIRO to clean up exploration datasets for AI algorithms

SensOre has commenced a joint project with the Commonwealth Scientific and Industrial Research Organisation (CSIRO) looking at automation and efficiency in big data cleaning and processing solutions for the mineral resource sector.

Access to high-quality datasets has, in the past, been an obstacle to applying cutting-edge predictive analytics to solve geoscience and mineral exploration problems, according to SensOre.

The joint project, which will confront this problem, will see several CSIRO data science experts embedded within SensOre over the next six months.

SensOre says it aims to become the top performing minerals targeting company in the world through the deployment of artificial intelligence and machine-learning technologies, specifically its Discriminant Predictive Targeting® workflow.

“SensOre is committed to world-leading mineral exploration research and development,” Richard Taylor, CEO and Director of SensOre, said. “This is the second time SensOre has worked with CSIRO and the engagement has led to order of magnitude improvements in our approach. Australian government support, such as the Kick Start initiative, is important for Australian technology companies looking to grow globally.”

The joint project benefits from CSIRO’s Kick Start initiative for innovative Australian start-ups, providing funding support and access to CSIRO’s research expertise. The program offers eligible businesses matched funding of up to A$50,000 ($34,681) to undertake research activities.

New survey to open up undercover exploration in South Australia’s Gawler Craton

New data collected from the Geological Survey of South Australia (GSSA) and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) is set to open up undercover exploration in the Gawler Craton.

The Gawler Craton Airborne Survey has been designed to capture approximately 1.8 million line kilometres of new magnetic, radiometric and digital elevation geophysical data over an area of some 324,000 sq.km.

The data will far surpass the current patchwork of surveys and provide a single, uniform dataset that will be fundamental in reinterpreting the geological structure of the Gawler Craton, according to the South Australia Government.

The Gawler Craton is host to the world-class Olympic Dam iron ore copper gold deposit, which hosts the world’s largest uranium deposit, as well as sizeable copper and gold resources. Several major copper mines including Prominent Hill, Cairn Hill, Mount Gunson, Hillside and Kanmantoo are also located here, in addition to projects like Carrapateena, Khamsin, Emmie Bluff and Punt Hill.

This week, the first data release of rock depth from the programme – focused on the north-western Gawler Craton – was published.

Officially opening the South Australian Resources and Energy Investment Conference (SAREIC) in Adelaide on July 30, Minister for Energy and Mining Dan van Holst Pellekaan said the information “will give explorers a head start on their exploration programmes and save precious time and money”.

“When it comes to exploring undercover, knowing the depth of prospective rocks is critical, given the cost and expense involved in drilling. This project is an international standout bringing an amazing clarity and precision in seeing through earth’s cover,” he said.

Today’s release is the first of 16 packages to be rolled out by the GSSA over the next 12 months covering the remaining Gawler Craton survey, and builds on previous releases of magnetic, radiometric and digital elevation data across a vast region of South Australia.

Despite many mines and prospects, the Gawler province is largely underexplored due primarily to the cover of regolith making exploration difficult. Statistical analysis of the type of orebodies present in the Gawler Craton, compared to similar style deposits globally, suggests there is an opportunity for more economic mineral discoveries to be found.
