Vic Tech Night: The Land that Time Forgot: The Victorian Eastern Goldfields

Thursday, November 25, 2021
1800
2000

ASEG Victoria is super delighted to announce the return of in-person branch events with an upcoming technical meeting night! You are invited to join us for a special presentation by Ian Nielsen (Chief geologist, First AU and Director of PGN Geoscience) on Thursday November 25th from 6pm at The Kelvin Club. This will be the last technical meeting night of the year for Victoria branch so come along and get busy sharing lockdown dramas with your peers over a drink or two.

 

The Land that Time Forgot: The Victorian Eastern Goldfields

Emerging geological models for evolution of the Eastern Australian continental margin involving accretionary orogenesis of the Southern Tasmanides has transformed Victoria gold and base metals prospectivity. Recognition of the same prospective Ordovician terrane that hosts significant central goldfields deposits at Bendigo and Fosterville in Eastern Victoria was proposed by various researchers over the past decade in which the formation of an orocline was established to constrain the relative rotation of the terrane about the Selwyn Block, now situated in Gippsland. A ground package was pulled together in 2017 with high-graded areas pegged during 2018 and 2019 by Victorian Goldfields Pty Ltd. The portfolio comprises several hundred historic high-grade gold workings amongst a myriad of complex litho-structural settings that includes several unique porphyry copper-molybdenum projects – further demonstration of the significant upside potential of the area.

 

The flagship Haunted Stream Project (EL006816) contains over one-hundred historic gold workings across an 8.5km strike length. Historic mining head grades were considerably high (>10-50g/t Au) matched with strong production rates for the late 19th century. The majority of hard-rock gold mining ceased prior to the first world war due to a number of contributing factors. Numerous gold mines were worked to depths of ~300ft, however difficulties encountered due to the ingress of water, metallurgical reconciliation and foul air, all of which were unable to be adequately addressed in the late 1890’s, drove miners out leaving an entire district poorly explored and opened at depth.

 

First Au Ltd acquired an 80% interest in Victorian Goldfields Pty Ltd in mid-2020 and has since spawned a new wave of exploration currently being undertaken within the district, including detailed litho-structural mapping and rock-chipping that has revealed a complex structural and mineralisation history. In-situ rock chip sampling from underground workings have returned grades in excess of 125g/t Au, underscoring the high-fertility potential of the region. A maiden drill campaign at Snowstorm earlier in 2021 produced very encouraging results with a best intersection of 3.1m @ 11.6g/t Au from 53m including 0.8m @ 33g/t Au from 54m. A follow-up drill program is currently being undertaken. First Au expects to also test a number of its copper-gold porphyry prospects in eastern Victorian during Q1 2022.

ASEG VIC Technical Meeting Night: Advances in the geoscientific application of computer vision

Wednesday, June 16, 2021
1800
2030

ASEG Victoria is pleased to announce the first of our winter series of in-person branch events with another superb technical meeting night.  You are cordially invited to join us for a talk by Mr. Mark Grujic (Director, Solve Geosolutions) on Wednesday June 16th from 6pm at The Kelvin Club.  Admission to this event is free for members so please ensure you have renewed your membership for 2021 before registering.

Advances in the geoscientific application of computer vision

 

One of the most common datasets available to exploration geoscientists is drill core imagery. Unfortunately, the huge range in quality and general state of core photography can be an impediment to many data-driven image analysis processes. In this talk, methods of dealing with some of the shortcomings of core photo data will be introduced.  Some such methods include the application of Self-Supervised-Learning to obtain models that are agnostic to lighting conditions, blur, resolution and other unwanted artefacts, as well as digital inpainting of geological information in photos that have been masked by core-markup or other obfuscations.  The validity of these processes to gain new insights from geophysical datasets including potential field geophysics data will be discussed.

 

Bio: Mark graduated from Monash university with a Bachelor of Science with Honours in geophysics. He spent 8 years with Rio Tinto Exploration in Perth and Santiago, initially working on geophysical hardware and processing algorithms, then supporting global exploration programs.  Since 2018, he has worked Solve Geosolutions, Australia’s first dedicated geo-data-science consulting group. In 2019, Solve launched Datarock, a mining and exploration focused computer-vision company, where Mark provides technical insight and product development support.

 

Note: Light refreshments will be served during the evening.

The Future of Cloud-based Spatial Geoscience Data and its Application in Exploration

Tuesday, May 25, 2021
1800
1900

ASEG Victoria is pleased to announce the second of our autumn series of in-person branch events with another technical meeting night.  You are cordially invited to join us for a talk by Dr. Fabian Kohlmann (Managing Director, Lithodat Pty Ltd) on Tuesday May 25th from 6pm at The Kelvin Club.  Admission to this event is free for members only, so please ensure you have renewed your membership for 2021 before registering.

 

 

The Future of Cloud-based Spatial Geoscience Data and its Application in Exploration

 

Well managed, standardized data is vital for the resource industry as it currently undergoes an intense digitalization phase. As most available geoscientific datasets are usually bound by regional extends and have their own attributes and requirements, it is often challenging to merge all data into a consistent global framework which can then be used across boundaries without limits. Lithodat’s vision is to provide geoscientists with global geoscientific databases and built-in analytics to gain fast new insights about regions of interest. To achieve that goal, a team of experts extract, validate and integrate data in our unique cloud-hosted relational database.

 

Rather than storing data from many different projects in separate spreadsheets and folders, Lithodat’s consolidation of data opens the full potential that spatial geoscience data has to offer. Using the right tools means that spatial relationships can be analyzed on the fly, helping to solve scientific questions and industrial demands alike. For that purpose, we have developed LithoSurfer, our online platform for data viewing, analytics and extraction. LithoSurfer gives quick access to regions of interest or dive into the wealth of additional information (analytical details, lab information, literature etc.) for each datapoint. All data can be extracted in multiple formats ensuring that new techniques such as machine learning (ML) and artificial intelligence (AI) can take full advantage of Lithodat's databases.

 

In this talk we demonstrate the data acquisition process starting in the field using our fully integrated LithoSurfer FieldApp, the range of data types captured, and tools developed to rapidly display spatial data information on LithoSurfer. The discussion also includes examples of the potential integration of new datasets within exploration workflows, and the development of new fully-integrated tools, such as on-the-fly paleogeographic reconstructions which lead to an improved understanding of tectonic events and changes in paleo-topography through time

 

Bio: After three years of Equinor sponsored post-doctoral work at Bergen University, Norway, Fabian joined Neftex Petroleum Consultants in 2013 to develop global paleo-digital elevation models and build a global thermochronology database for integration into plate modeling, basin modelling and gross depositional environment mapping workflows. After Neftex became part of Halliburton, he was put in charge of the thermochronology team and became part of Halliburton’s global Source-to-Sink project. Fabian left Halliburton in 2018 to join Lithodat Pty. Ltd., a new cloud-hosted geoscience data company based in Melbourne. Fabian holds a PhD degree in Earth Sciences from the University of Melbourne and a MSc degree in Geology and Paleontology from the Ludwig-Maximillian University in Munich, Germany.

 

Note: Light refreshments will be served during the evening.
