Mining Prospects High for Cornwall

Cornwall, UK, is synonymous with tin mining, having built its fortunes in previous centuries extracting and producing the metal for export around the world. A new and exciting project has now been launched that will build on Cornwall’s mining heritage with an ambitious proposal to recover tin deposits from the waters off the North Coast of Cornwall. Marine Minerals Ltd (MML) is a Cornish company created to investigate the viability of this project and Coastline Surveys was asked to play a major role in the early investigative surveys to establish the characteristics of the mineral bearing sands off the coast...

AUV Operations in Marine Mining

DBM GEOSURVEY is the marine survey arm of De Beers Marine, the world’s largest marine precious mineral mining company. DBM GEOSURVEY has pioneered the development of geophysical survey systems over the past 20 years to improve mineral resource development and support DBM’s mining activities. Core to this development was the decision to adopt autonomous underwater vehicles (AUVs) as the primary survey platform. We look back on the challenges and successes of 7 years of AUV operations.<P> One of the key factors crucial to the success in offshore diamond mining and exploration operations is the ability to improve geological understanding of...

IHC Mining Joins World Ocean Council

IHC Mining, part of Royal IHC (IHC, The Netherlands), has become a member of the World Ocean Council (WOC). As a leader in responsible dredging and offshore mining activities, it is expanding its scope as one of the pioneers in deep-sea mining with initiatives such as this. IHC Mining is working towards reaching deep-sea mineral deposits. This is being achieved with the support of a dedicated research and development program, as well as through its position as a leader of the EU Blue Mining project. The company is also demonstrating its commitment to understanding and addressing the environmental aspects of... (read more)

Geosurvey Techniques in Offshore Diamond Mining

De Beers Marine routinely acquires ultra high-resolution geophysical data in support of its offshore mining and exploration programmes for diamondiferous placer deposits situated on the continental shelf off the West Coast of southern Africa. Geosurveys are conducted over a wide range of water depths, each with a unique geological seabed terrain and associated survey requirements. Detailed mapping of complex and varied geological terrain demands the use of leading-edge survey technology. To this end, we have for the past four years been routinely operating an AUV (Autonomous Underwater Vehicle) as our principal ultra-high resolution geophysical survey platform. The continental shelf off... (read more)

3D Modelling Software for Marine Mining

AuruMar, headquartered in South Africa, has purchased Maptek Vulcan 3D modelling software for its marine continental shelf exploration operations. AuruMar will apply Vulcan GeoModeller to the mineral resource development programme for its 26 mining leases offshore of Nome, Alaska. The company wanted to be able to look at and model its geological data in 3D, according to Urban Burger, AuruMar geologist. Vulcan GeoModeller provides a complete set of tools for exploration and mining geologists with functionality for both stratigraphic and non-stratigraphic deposits. AuruMar is a technical services company based in Cape Town, South Africa. It was established in October 2009... (read more)

Deep-sea Mining Exploration Aided by Corers

Deep-sea mining is a relatively new process of extracting minerals from deep sediments. Exploration of potential sites can be problematic, but these undertakings can be facilitated by the use of the OSIL Giant (Jumbo) Piston Corer, which can retrieve sediment cores up to 60m in length, and the OSIL Multi Corer, which can take up to 12 high-quality undisturbed samples simultaneously. The OSIL Giant (Jumbo) Piston Corer is used in the exploration and identification of zones of strategic deep sea mineral deposits like poly-metallic nodules, hydrothermal sulphide deposits containing base metals along with gold, cobalt, nickel and silver and cobalt-nickel...
