Canada: Mining industry can utilise remote sensing (RS) technique to gather cost effective information, observed David McLelland, owner of Auracle Geospatial Science, a remote sensing and geospatial company in British Columbia. McLelland said that remote sensing is a cost-effective way to gather and analyse vast amounts of information from large areas without being on the observed surface.
McLelland highlighted the importance of RS technique for mining industry keeping in mind the increased rates. From July 1, 2012, companies and individuals will have to pay double the value of the corresponding assessment work requirement for Payment Instead of Exploration and Development (PIED). The previous rates were equivalent to the value of exploration and development work. These changes will impact decisions companies and individuals, as there is a risk of forfeiture if assessment work is not completed on time and companies are not able to come up with the additional money to pay the fees. This can be a serious problem since forfeiture makes it possible for other companies and individuals to acquire the mineral tenure.
McLelland further said that remote sensing qualifies as exploration work under the Mineral Tenure Act (MTA). “It would be unfortunate for companies to lose mineral claims that are still valuable and of interest because they haven’t completed work and can’t generate the extra fees,” he explained.
Remote Sensing doesn’t require social license or a permit so there are no additional permitting costs and it is something that can be started immediately. It can be conducted without public scrutiny.
Auracle Geospatial Science has developed specialised protocols to fuse multivariate image multi-temporal spectral satellite data, radar sat panchromatic data and knowledge based geological data to produce a new type of image of the area. These new images more clearly identify fault structures, rock lithologies and alterations that are not visible on simple satellite images, aerial LiDAR images or geological maps. Structures and alterations that have the highest probabilities of containing mineralised areas are identified so that exploration can concentrate on more detailed and narrow targets. These methodologies have been used to identify probable scarns, porphories, veins, surficial uranium deposits, SEDEX, VMS and kimberlites.
