20 November 2017: MSDP plays a role in DET CRC success
The DET CRC’s final AGM video was posted this week and underlined the crucial support the MSDP played in demonstrating and advancing several of DET CRC’s technologies. In total, the MSDP and associated trials featured in 5 out of 10, 2016-2017 highlights.
September 2017: New interpretation of Mineral Systems Drilling Program drill core released
Detailed lithological logging of three MSDP drillholes in the Six Mile Hill area has provided new insights into the depositional environment and controls on thickness and distribution of the Gawler Range Volcanics in the southeast margin of the Gawler Ranges.
September 2017: Mineral Systems Drilling Program – testing & delivering tomorrows mineral discovery technologies
The Mineral Systems Drilling Program provided an opportunity to showcase and test pre-commercial technology being developed within the DET CRC within a supportive real-life exploration program. These technologies are being developed to directly address technical challenges of the minerals industry.
Technology trials incorporated into the MSDP focused on several aspects of reducing the cost of exploration:
- collect real-time data to assess prospectivity and make decisions that will improve the effectiveness of a drill campaign;
- accurately monitor drilling parameters to improve penetration rates and reduce bit wear; and
- deploy low cost seismic surveys to provide constraints on the depth to key surfaces and sub-surface architecture.
All technologies trialled progressed along the Technical Readiness scale. One such example was the Wireless Sub (monitors real-time drilling performance), which following extensive testing during the MSDP, was subsequently licenced by Boart Longyear, the leading global supplier of drilling services, drilling equipment and performance tooling.
Facilitating product development through trials of DET CRC technologies was paramount in making the MSDP so successful and relevant to the wider minerals industry.
12 September 2017: Mineral Systems Drilling Program report released
A comprehensive review of MSDP results and outcomes have now been compiled. The report not only provides geological insights from the 9 month drilling campaign along the southern Gawler Ranges, but summarises key results of trials of DET CRC technology.
November 2016: GSSA's southern Gawler Ranges outcrop rock sample collection on display
More than 100 rock samples were collected as hand specimens during GSSA’s geological mapping program that was carried out alongside the MSDP drilling. These samples were exhibited for the first time during the MSDP Open Day in August 2016 and are now compiled in a pictorial catalogue that has been released as a new Report Book.
The rock samples were collected in the three MSDP drilling areas as well as adjacent areas along the southern margin of the Gawler Range Volcanic Province. The samples include various rocks from basement to the GRV including felsic and mafic intrusive rocks of the newly defined Peter Pan Supersuite. The collection includes a wide variety of lower and upper GRV facies such as rhyolites, granites, breccias and volcaniclastics, as well as examples form the Meso- and Neoproterozoic cover and regolith.
This impressive rock collection will be on display at the upcoming Discovery Day on 1st December 2017 at the Adelaide Convention Centre.
11 August 2016: A new map to guide mineral explorers through the regolith of the Southern Gawler Ranges Margin
The new regolith map of the Southern Gawler Ranges Margin provides a valuable regional overview of the main regolith types and their associated landforms, a general outline of the major areas of bedrock or regolith dominated terrain as well as the occurrence of in-situ versus transported regolith of this emerging mineral province.
It aims to provide a broad-scale framework for guiding geochemical prospecting for a wide range of minerals and materials, as a basis for guiding mineral exploration, and to provide a useful dataset for addressing other land use issues like groundwater.
11 August 2016: Next generation of integrated geophysical models
The South Australian Geophysical Reference Model (SAGRM) is a valuable new research and exploration tool, which enables users to visualise, query and interpret the state’s vast archive of geophysical datasets in a full 3D environment. This is the first time a model of this size, complexity and completeness of geophysical data has been produced anywhere in the world. The model is a significant contribution to the lithospheric architecture theme of the UNCOVER initiative. The SAGRM is designed to be readily updateable and will incorporate new datasets, such as AusLamp, AusArray and the Gawler Craton magnetic survey, as they become available.
16 May 2016: MSDP finds evidence of mineral system
The final phase of the Mineral Systems Drilling Program (MSDP) involved seven holes for a total of 3,127m drilling on the north-western Eyre Peninsula. The holes were intended to test a range of potential precious and base metal mineral systems, comparable to the Paris and Menninnie Dam prospects further east. Drill holes intersected a fascinating suite of rocks inclusive of; alteration zones with low levels of visible base metal sulphide (MSDP10), magnetite-rich skarn with minor pyrite and trace base metal sulphide (MSDP11) and silica and sericite altered metaigneous and metasedimentary rocks with pyrite veining and low levels of visible base metal sulphides (MSDP12) (after Minotaur Exploration Ltd, Quarterly Report Period ended 31 March 2016). These rocks are proving to be very useful in benchmarking the performance of technology developed by the DET CRC including the Lab-at-Rig®, AutoSonde and AutoShuttle in the identification of rock types, alteration zones and subtle signatures of mineralisation in a greenfields exploration setting. We await the results of laboratory assays which will be reported by Minotaur Exploration in due course.
5 April 2016: MSDP drilling continues in Mt Double region
Drilling continues in the Mt Double region as the program nears the completion date of 2nd quarter 2016. The MSDP has utilised Investigator Resources Paris camp for recent field operations.
Early morning discussions over core layout
March 2016: New GSSA report describes the evolution of the GRV in the Roopena area
The lower Gawler Range Volcanics exposed in the Roopena area provide a rare example of mafic and felsic volcanism synchronous with sedimentation in a lacustrine setting. In the subsurface this volcanic sequence extends northwards to the MSDP Cariewerloo drilling area, and is bound by a N-S-trending fault system which appears to have been active during volcanism.
Report book 2015/00021 ‘Stratigraphy of the lower Gawler Range Volcanics in the Roopena area, northeastern Eyre Peninsula’ contains detailed petrological descriptions of the Roopena Basalt, Angle Dam Volcanics and Fresh Well Formation, as well as lithological and stratigraphic logs of 25 drill holes in the Roopena area. By identifying sedimentary and volcanic time markers across the basin system, a model for the spatial and temporal evolution of the volcanosedimentary sequence has been constructed which discusses the interactions between volcanism, sedimentation and tectonism.
