27th April 2021 Snap meeting: 27th April 2021 “Challenging the Orthodoxy of Traditional InSAR Ground Motion Surveys

Presented by: Dr. Andrew Sowtor, Chief Technical Officer of Terra Motion

Over the last 20 years or so, Interferometric SAR (InSAR) has become an established method for measuring land motion from satellites and, since the advent of free data from remote sensing missions such as Sentinel-1, can be a very cost-effective way to support civil engineering and infrastructure asset management projects.  However, there is a serious downside in that most current techniques, such as PSInSAR and SBAS, are very poor at monitoring motion over rural landcover, such as soils and vegetated surfaces.  In this presentation, Dr Andy Sowter from Terra Motion Limited will describe the current capability of satellite InSAR and, using case studies from the mining industry, show how he and his colleagues have seriously challenged the preconceptions of InSAR experts everywhere, opening up new and exciting opportunities for ubiquitous and remote ground motion monitoring at all latitudes and in all terrains.

This years MinSouth heat winner: Alex Lipp, RSM, “All the world in a grain of sand? Geochemical surveying by unmixing of large-river sediments”

Geochemical surveying provides information essential to mineral exploration and environmental baseline monitoring. However, dense spatial surveying is costly, slow and logistically challenging. Novel methods which can produce geochemical maps but minimise these downsides are therefore highly desirable. Typically, geochemical surveys sample stream-sediments from small river catchments across the target region. Here, I will describe how we can instead use smaller numbers of samples extracted from large rivers to reconstruct the geochemistry of the source region. This novel approach ‘un-mixes’ the geochemistry of downstream sediment samples using an inverse method to produce a geochemical map of the source-region. This approach is demonstrated with a case-study from the Cairngorms, UK: using just 67 downstream samples we are able to produce geochemical maps that compare favourably with independently gathered geochemical-survey maps produced with more than 100 times as many samples. This novel method could therefore reduce the logistical, temporal and financial cost of geochemical mapping.

Finlay Goodwin, CSM, “The Tin Bearing Pegmatites of Uis, Namibia”

The area of Uis is situated within the Erongo region of Namibia. The area comprises the margins of several granite plutons, likely to represent the upper, fluid-saturated cupola of intrusions that themselves contain zones of intense tourmalinisation and pegmatite formation. These granite-hosted pegmatites do not contain tin mineralisation. By contrast, the exogranitic pegmatites in the Uis pegmatite belt are pervasively stanniferous and CGM-bearing, and are believed to be metamorphogenic in origin, related to the late stages of the Damaran orogenesis – accordingly they are likely to be genetically unrelated to the adjacent granite intrusion. Characterisation of the contrasting mineralised and unmineralised pegmatites is considered to be important for any future assessment of the prospectivity of the region. In this presentation, an alternative hypothesis is put forward, presenting evidence that the Uis pegmatite swarms may have evolved along a single liquid line of descent from a granitic parent magma.

Alexander Moss, CSM “Exploration for LCT Pegmatites in Leinster, Ireland”

Lithium bearing pegmatites were first discovered along the eastern margin of the Leinster Granite, Ireland in the 1980’s. At the time it was noted “if only we have had a use for lithium”, now, 40 years on, societal demand for lithium is set to increase due to the rise in interest in EVs and the green agenda. Following this increase in interest in lithium, prospecting for lithium in the area was renewed. Modern mineral exploration techniques were deployed, including geostatistics, to build a model of lithium prospectivity for the region. The known occurrences of lithium mineralisation were used to train a fuzzy logic model of lithium prospectivity along the eastern margin of the Leinster Granite, before extending its utility to northern portions of the Leinster Granite. This study presents the geostatistical methods utilised, including potential issues with the technique and ideas for future work and improvements to the model.

12th November 2020 Sensors and Mining, virtual meeting.

Andrew Bamber from BARA Consulting Presents: Modifying your Modifying Factors with the use of Sensors.

Sensors come in many forms and can be used for many things, but possibly the best use of sensors is for the discovery, definition, and characterization of ore bodies both before and during mining activity. This talk will review several types of sensor plus examples of use in each of these roles, and present some case study examples of where either significant dilution or loss was avoided through the application of sensor technology.

14th November 2019, MinSouth Exploration Forum:

Antony Benham of SRK Exploration provides an update on what we know so far about the geology and prospects of the Arabian-Nubian Shield

Simon Large of the Natural History Museum talks about the FAMOS project in general and his work on the giant Los-Bronces porphyry Cu deposit district (Chile). He will show how they integrate current research interests in igneous petrology with application to exploration.

14th October 2019 Pat Willis of Bara Consulting shared some lessons learnt through performing feasibility studies. Over the last 10 years or so Patrick Wills of Bara Consulting has undertaken numerous studies and reviews. He will share some of the more important lessons learnt and personal frustrations in undertaking studies.  He will then highlight some common issues arising from reviews (be they formal due diligence, expert witness roles or peer reviews). He stresses that this is not a tick box on how to undertake studies or how to comply with stock exchange codes but rather a more light-hearted approach to the subject.

9th September 2019 Philip Shaw of SureWave Technology Ltd gave a short presentation on new technology for monitoring of tailings dams, followed by a panel discussion with Hans Otto, Senior Tailings Engineer with Golder Associates (MinSouth Silver sponsor) and Brett Garland of Knight Piésold (MinSouth Silver sponsor).  Thank you Brett for standing in for John Thuysbaert who was called away on the morning of the talk.
