WHY PHOTOSAT?
SATELLITE SURVEYS ACCURATE TO 20 CM, CONSISTENTLY, ON ANY SITE IN THE WORLD
A published case history for drone survey of a 150km² mine development project in Madagascar is compared to a 357km² PhotoSat survey of a similar project in Peru.
The Drone survey took a 3 person crew, 90 field days to acquire, and 120 days to process on a single processor.
The PhotoSat survey of 357km² in Peru took 8 days to obtain the satellite photos and 11 days to process. This project took 34 days from confirmation of the order to the delivery of the results.
DEEP LEARNING ALTERATION MINERAL MAPPING GENERATE NEW EXPLORATION TARGETS
Two satellite systems and processing methods detect and map a wide range of alteration minerals key to exploration targeting.
For epithermal gold and silver, and porphyry copper exploration, WorldView-3 and ASTER satellite photos are used to map clay, iron oxide, and silica minerals. A wide range of mineral assemblages can be identified with WorldView-3 spectral matching.
PhotoSat vs. InSAR: Two Distinct Technologies
Both PhotoSat and InSAR rely on satellites to capture images. But in application, these two technologies are distinctly different. In reality, they are vastly more different than they are alike.
Investing in the right kind of data is crucial. PhotoSat’s unique technology makes it possible to measure elevation to a high vertical accuracy. In contrast, InSAR detects subtle movements on the surface.
Remote Surveying Technology and COVID-19 Safety
The global pandemic has changed the way the world does business, and most sectors have been disrupted by the spread of COVID-19. In the new normal of social distancing, mining companies are searching for new ways to safely continue operations.
Updated survey data is critical to safely manage mine sites and monitor TSFs. But under pandemic conditions, some survey methods may be impractical or even impossible to rely on.
