— To achieve this, many different types of geoscience data and information are combined in advanced multi-methodologically approaches to develop complex high-resolution exploration models in modern mineral exploration. Geophysical methods play a central role in such kind of exploration since they allow non-invasive systematic …

— An airborne magnetic and radiometric survey, conducted in the Mindarie district of South Australia, detected a large number of very weak linear magnetic features disguised by magnetic noise caused by iron oxides in surface sands and cultural features. Enhancement of the aeromagnetic data, to emphasise linear features striking parallel to …
Canada, many of the practices described herein can be adapted to mineral exploration activities in other countries. The Exploration Guidelines are not intended to inhibit original thinking, or to prevent the application of new approaches that may develop into fundamental components of successful mineral exploration programs.
— Mining - Prospecting, Exploration, Resources: Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing …
— Electrical resistivity (ER), induced polarization (IP), and self-potential (SP) are three geophysical methods that have been broadly used in the realm of mineral exploration. These geophysical methods provide complementary information, each exhibiting a distinct sensitivity to various types of mineral deposits.
— The emergence of the concept of a "mineral system" has changed the way regional-scale mineral prospectivity is assessed. Geographically widespread data sets and deep-penetrating geophysical methods are required to map the various components of the mineral system, which may encompass areas of perhaps thousands of square …
— Rare-earth elements (REE) are an essential component of numerous advanced technology applications including high efficiency batteries, emerging energy technologies, and key defense systems. The goal of this study was to assist in the evaluation of the distribution of rare earth element deposits in the southeastern U.S., …
Mineral sand deposits contain a concentrated amount of economically important minerals known as 'heavy minerals', which are much heavier than common sand minerals such …
Seismic methods provide high-resolution images of geologic structures hosting mineral deposits and, in a few cases, can be used for direct targeting of mineral deposits. Applications are not limited to only surface …

— Seismic imaging is now a well-established method in mineral exploration with many successful case studies. Seismic data are usually imaged in the time domain (post-stack or pre-stack time migration), but recently pre-stack depth imaging has shown clear advantages for irregular/sparse acquisitions and very complex targets. Here, we …

— The mineral exploration industry requires new methods and tools to address the challenges of declining mineral reserves and increasing discovery costs. Laser-induced breakdown spectroscopy (LIBS) represents an emerging geochemical tool for mineral exploration that can provide rapid, in situ, compositional analysis and high-resolution …
— The most effective exploration methods for these deposits include identification of trailing continental margins with Neogene to Quaternary coastal strandlines and dune fields spatially related to …
— Commonly, exploration soil samples are sieved to <250 µm or <180 µm to remove larger gravels and coarse sand and, in some cases, then pulverized for analysis, but no other refinements are undertaken on the soil samples. However, are these <250 µm or <180 µm fractions the appropriate ones for mineral exploration?
— The magnetic method is the primary exploration tool in the search for minerals. The magnetic method has evolved from mapping basement structure to include a wide range of new applications, such as locating intra-sedimentary faults, defining subtle lithologic contacts, and mapping salt domes in weakly magnetic sediments.
The magnetic method is still one of the most popular and intensively used methods in mineral exploration. The reviews by Nabighian et al. ( 2005 ), Vallée et al. ( 2011 ), and lately Hinze et al. ( 2013 ) with included references provide a substantial overview on this method, the sensors used, the instrumentation, and data acquisition as well ...

Heavy mineral sands are natural sedimentary deposits containing economic quantities of rutile, ilmenite, zircon, monazite, and xenotime. These heavy minerals are sources for pigments, high-grade titanium feedstock, glazes, industrial additives, and even abrasives. Heavy mineral sands are being explored as sources of rare earth elements like …
