FISSION URANIUM CORP. and Special Projects Inc (SPI, Calgary), are pleased to announce the filing of a patent application for an invention entitled “System And Method For Aerial Surveying Or Mapping Of Radioactive Deposits”. The invention relates to an airborne system and method for surveying a geographic area to detect and map the locations of radioactive geological deposits, such as boulders and clusters of rock.
The invention results in a particularly high-resolution survey and is an improvement over known airborne surveying methods for radioactive deposits. The invention led Fission to discover the high-grade uranium boulder field at its Patterson Lake South (PLS) property in Canada’s Athabasca Basin, home to the world’s richest source of high-grade uranium.
Ross McElroy, President, COO and Chief Geologist of Fission Uranium, commented,
“Using our patent-pending survey system, enables us to quickly and effectively explore large areas for radiometric anomalies. Our system has proved to be incredibly sensitive and accurate in locating anomalies of interest and provides a “leading-edge” ability to find occurrences of radioactive soil, boulders and outcrop at surface that may represent uranium.”
Radiometric surveys are regularly employed in exploration to detect and map natural radioactive emanations (from uranium, thorium and potassium), from rocks and soils. Meteorological conditions, the topography of the survey area, the influence of the Earth’s cosmic environment, the height of the sensor above ground and the speed of the aircraft are some of the variables which affect radiometric measurements. The invention resulting from the collaboration between Fission’s technical team and SPI is particularly sensitive to addressing these variables.
Prior to the Fission/SPI invention, airborne prospecting for radioactive minerals has been generally carried out by flying a fixed wing aircraft equipped with large detectors relatively high altitudes and high speeds over a geographical region to be surveyed. However, data collected in such a manner often does not allow for detection of localized geological deposits such as boulders and clusters of rock due to the large footprint of the measurement and the resulting background-to-boulder signature ratio. Additionally, many legacy systems, which used a combination of towed magnetometer sensors and large detector systems, lacked the electronic navigation and data acquisition tools required to collect and compile the information in a manner required to detect localized geological deposits.
The Fission/SPI invention utilizes a fixed wing aircraft using at least one radiation detector element to fly at an ideal height and speed over a geographic area and store the radioactive signal data. Furthermore utilizing advanced processing technology to map the radiation signal data to accurately identify and flag high priority points, which in the case for PLS resulted in the discovery of the high-grade uranium boulders.
FISSION URANIUM CORP. announces the discovery of two significant and strongly radioactive uranium source anomalous regions on its 100% owned North Shore property in the Athabasca Basin, Alberta. The Northern and Southern anomalies occur within the south-central part of the project area near the southern boundary. The discovery was made using Fission and Special Project Inc’s (‘SPI’) high resolution magnetic and radiometric airborne survey technology which is currently patent-pending (see news release July 16, 2013).
The Northern anomalous region occurs within a 1.5km x 0.5km area and contains several parallel trends up to 300m. The Southern anomaly is located approximately 7km to the SW of the northern anomaly and is characterized by being narrow (1 to 10m wide) and can be traced for up to 3km.
Ross McElroy, President, COO, and Chief Geologist for Fission, commented,
‘We are very encouraged by this strongly radioactive discovery, particularly as we used the same technology to locate the boulder field at Patterson Lake South (PLS). While the expansion of our PLS discovery is our main task, following up these new results at our North Shore property is also a priority.’
In August 2013, using a fixed wing aircraft, SPI flew a 12,257 line km high resolution airborne magnetic and radiometric survey at 50m line spacing over the entire North Shore project. The radiometric system uses a calibrated gamma spectrometer which is able to differentiate between uranium, thorium and potassium and also determine the relative concentration of each element.
The radiometric data was collected and processed and anomalies were picked based on elevated total counts with correlated elevated uranium concentrations. The width and responses of the peaks indicate that some of the larger anomalies present are likely to be part of the outcrop/sub crop as opposed to boulders. This is indicated by a generally wider anomaly which is easily seen on multiple lines.
