About this event

This course will provide interested geoscientists with the knowledge and skills necessary to effectively use gravity and magnetic tensor data for minerals and energy exploration. At a time when explorers are looking for deeper and under cover deposits, the workshop will demonstrate the value of gradiometric data to solve these challenges, when combined with innovative interpretative techniques. Although both techniques have been available for more than 2 decades, many users still rely on one tensor component only or unconstrained inversion for their interpretation. The workshop will debunk the myths about tensor data complexity and familiarise geoscientists with the latest qualitative and quantitative interpretation techniques which can translate geophysical information into meaningful geological outputs. This will be illustrated by recent case studies. Some knowledge of gravity and magnetic data for exploration is an advantage but the course focuses on applications rather than theory, so that geoscientists with a geological background can benefit.

What I will learn
  • Full Tensor Gravity Gradiometry (FTG) & Full Tensor Magnetic Gradiometry (FTMG) techniques for exploration
  • When to use FTG & FTMG
  • How to design surveys effectively for minerals exploration
  • How to analyse tensor data: interpretation workflow for tensor data
  • FTG & FTMG in practice: Case studies
  • Modern software for FTG & FTMG data: Intrepid Geophysics tools

Bell Geospace has been at the forefront of Gravity Gradiometry for over 30 years. Bell Geospace provides exploration companies with Full Tensor Gravity Gradiometry (FTG) and magnetic data to enhance sub-surface models and de-risk exploration projects.

Explore Province to Play, Efficiently
Airborne geophysics with FTG allows fast screening and ranking of prospective areas at the province and district scale, de-risking ground exploration at prospect and play scale. Accurate and informative data enhances existing complementary data and fine tunes a strategy for future acquisition.

African Gold Exploration
Bell Geo's FTG, gravity and magnetic data acquisition technology is especially good at locating contact zones and faults, suitable for finding the mineralized geology which hosts gold. Bell Geo’s most recent gold exploration project took place in West Africa. Gaud Pouliquen and Colm Murphy can share more details about this in person at SAGA.
Energy-Metals Exploration in Africa
Geoscientific methods are more critical than ever for energy-supply sustainability. Structural and lithological information to demystify subsurface mineral systems is required on a new, larger scale. If you're exploring in the Kalahari and Zambian copper belt, ask us at SAGA about Bell Geo’s experience in Botswana, Zambia, South Africa... and beyond.

New Interpretation Methods
The mines of tomorrow are hidden beneath layers of sedimentary cover or nestled as subtle extensions to known deposits. While traditional airborne geophysics excel in detecting metal deposits near the surface, they struggle when encountering deeper targets or non-magnetic geological trends.

Exploration teams seek to deploy high-resolution technologies on surveys with closely spaced lines or stations covering extensive areas. These surveys should capture a broad signal bandwidth to map the deeper extensions and connectivity with shallow structures effectively. However, such practices are not always feasible due to challenging terrain, including water bodies, vegetation, restricted access, or the significant time and budget required to acquire such data across large areas. Bell Geospace's FTG technology overcomes many of these limitations. With our latest workflows, signal bandwidth resolves shallow complexity and allows confident mapping at depth and will deliver geological structures and shapes within a given depth interval/window.

VISION OF SAMERDI

“To maximise the returns of South Africa’s mineral wealth through collaborative, sustainable research, development, innovation and implementation of mining technologies in a socially, environmentally and financially responsible manner that is rooted in the wellbeing of local communities and the national economy.”

THE MANDELA MINING PRECINCT,

officially opened on 4 May 2018, provides the opportunity to have a community of researchers working together in the same space on related subjects both from an inter- and intra-organisational perspective.

THE SOUTH AFRICAN MINING EXTRACTION, RESEARCH, DEVELOPMENT AND INNOVATION (SAMERDI) STRATEGY

The SAMERDI Strategy, as an outcome of the Mining Phakisa, provides a roadmap on how to work collectively towards technological solutions that will increase safety and productivity, and reduce costs to ultimately extend the life of mines by:

Improving the competitiveness of the sector and creating new opportunities for South African based companies to operate in areas along the entire value chain; and

Reposition South Africa as the world leader in mining RD&I by building human resource skills, capabilities, and capacities across industry, academia and the science councils, ensuring its sustainability.

The SAMERDI Strategy provides a roadmap on working collectively towards technological solutions that will increase safety and productivity, reduce costs, and ultimately extend the life of mines.

Thus the implementation of the SAMERDI strategy through collaboration and support from researchers (science councils and academia), government depart­ments, mining houses (individually and collectively), and organised labour unions can be the solution to the chal­lenges that beset the mining sector.
