Mapping hydrothermal alteration minerals and structural lineaments using Landsat 8 multispectral imagery provides valuable information for mineral exploration. In northern Portugal, there are several known gold occurrences, but there is the potential to identify new anomalous areas. Gold mineralization occurs in the form of quartz veins and …
The team also calculated artisanal mining activity by year to pinpoint its rise in popularity over the past decade. The map above shows new mining activity over a subset of the study period from 2007 to 2017 near Kumasi, Ghana. (The researchers chose 2007 to 2017 to focus on years with sufficient cloud-free imagery to identify annual changes.)

The new algorithm was trained on small image samples, some of which contained a part of a dam or mine, annotated with the presence or not of a mine or tailings dam and the ore type if it was known. The data acquisition process was detailed in Section 3.1. Each image sample covers a 2 × 2 km area (201 × 201 pixels).
Hyperspectral remote sensing already is important in geoscientific research in the fields of geology, soil, exploration and mining. New hyperspectral satellite systems are already in operation (e.g. PRISMA and DESIS; Caporusso et al. 2020; Alonso et al. (Sensors 19(20):4471–4515, 2019)) and more systems are planned e.g. the European …

El-Arafy brings samples collected in Egypt to UAB's Scanning Electron Microscope facility in the ...
In recent years, various geological activities and different mineral prospecting and exploration programs have been intensified along the Red Sea hills in order to elucidate the geological maps and to evaluate the mineral potentials. This study is therefore aimed at testing the viability of using remote sensing and geographic information system (GIS) …
Mark Altaweel | GIS Data | April 11, 2018. Mapping minerals from space was one of the main motivating reasons for creating the earliest multispectral satellite systems such as the Landsat satellites when they …
Multispectral imaging is already used in satellite, drone and aircraft-based systems in the hunt for new valuable mineral deposits on Earth, and it's also starting to be used in space! The next step is likely hyperspectral imaging. Routine use of existing hyperspectral systems by the minerals industry has been hampered by the unavailability ...
Abstract and Figures. This work explores the combination of free cloud computing, free open-source software, and deep learning methods to analyze a real, large-scale problem: the automatic country ...
6. Geo-Airbus Defense. Just like Maxar, Geo-Airbus Defense is a commercial vendor.SPOT, Pleiades, and RapidEye are some of the best in class. Geo-Airbus Defense also has a collection of sample imagery. But unfortunately, their free satellite imagery selection is quite limited.
Here we present a new dataset that improves global mining land use accounting by significantly expanding our previous global-scale dataset of mining sites 21, 23. The data update includes 44,929 ...
Here, we produce a global mining land use dataset via remote sensing analysis of high-resolution, publicly available satellite imagery. The dataset comprises …
WorldView-3 satellite data with 30 centimeter pixel resolution provides the highest commercially-available level of image detail. Colorful mining ore stockpiles, …

Using satellite imagery for greenfield exploration. Fabian Dechent. March 19th 2021. Unsurprisingly, a major requirement that makes mining endeavours successful is the right location - one where the enterprise knows with confidence that the soil bears high grade minerals of interest. Finding such a site, however, poses a significant challenge.
Mineral Resources Data System (MRDS) MRDS describes metallic and nonmetallic mineral resources throughout the world. Included are deposit name, location, commodity, and references. Some records include deposit description, geologic characteristics, production, reserves, and resources. It includes the original MRDS and MAS/MILS data.
The sensors: bits-per-band, spatial resolution and wavelengths. Landsat 8 carries two sensors: the Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS). Only the OLI is relevant to …
In the Huaniushan metal mining area, hyperspectral images are processed by spectral calibration and classification, and the results are compared to existing 1:10,000 geological mineral maps.
The workflow of geodata science-based mineral prospectivity mapping (GSMPM) (Fig. 2b) underlines the spatial correlations between geological, geochemical, geophysical, and remote sensing patterns with known mineral deposits. The identification of mappable layers is based on revealing the spatial associations between geoscience data …
