Update March 2017:

X-Terra Resources also wishes to report that preliminary data from its recently completed airborne geophysical survey has been received. Michel Chapdelaine, a director and member of the technical committee of the Board of Directors of X-Terra Resources commented, “The quality of the survey is impeccable and the first interpretations completed by MB Geosolutions are as well. The precision of the data will enable X-Terra Ressources to precisely target their exploration. In addition, the Veronneau showing is located on a ½ kilometre per 2 kilometres area where the MagEM signature is unique as it is very different compared with the rest of the property. We can see certain electromagnetic conductors seem to recut the principal structural grain”.

The United States Geological Survey (USGS), University of Wyoming and Aarhus University in Denmark are applying the SkyTEM method to collect data over portions of Yellowstone National Park.  The objectives of the airborne survey are to map lithological variations and structural controls on groundwater flow within the Park to delineate zones of cold fresh water, hot saline water, steam, clay and unaltered rock to gain a better understanding of Yellowstone’s myriad hydrothermal systems.  The high quality data collected by the SkyTEM312 time-domain electromagnetic system data are intended for rigorous inversion and interpretation of the 3-D hydrogeologic conditions of the subsurface and will provide the first subsurface view of Yellowstone’s hydrothermal systems, tracking the geophysical signatures of geysers, hot springs, mud pots, steam vents and hydrothermal explosion craters to depths in excess of 1,000 feet.

The engineering built into SkyTEM technology is centered on the ability to deliver airborne data comparable to data collected by calibrated ground geophysical instruments.  SkyTEM has carried out several surveys for the USGS in California, Montana, Nebraska, Colorado, Washington and Alaska.  Over the last decade SkyTEM has completed many groundwater projects for governments, scientific organizations and private industry world-wide.

Water survey in California

California is suffering from drought and lack of drinking water. That is the reason why the U.S. Geological Survey (USGS), in cooperation with the California Water Resources Control Board, has contracted SkyTEM to conduct an electromagnetic geophysical survey of the subsurface in Southern San Joaquin Valley. The purpose of the survey is to protect all waters and monitor the groundwater that has the potential to be a source of drinking water and to characterize and monitor risk zones.

The survey is scheduled to start end September.

SkyTEM survey

304 to Yuma. SkyTEM technology maps groundwater in Arizona

SkyTEM survey USAThe SkyTEM304 airborne geophysical system will soon be mapping groundwater resources in Arizona.  The Bureau of Reclamation (BOR), Yuma, Arizona, manages groundwater commitments to critical water districts that use the Colorado River, Gila River, and Yuma area groundwater resources for irrigation and other agricultural activities. The Yuma Area is one of the most heavily-farmed areas in the United States and agriculture here accounts for an annual gross economic return of $3.2 billion. Crops are grown year-round and miles of water delivery infrastructure ensures the agricultural industry is successful. In order to better meet Arizona’s water commitments today and sustainably in the future the BOR is using the SkyTEM airborne geophysical method to characterization groundwater resources in the greater Yuma area.

Data from SkyTEM systems are used as input by scientific organizations and governments worldwide to help them better understand and manage groundwater resources. The team assembled for this project consists of Southern Helicopters, XRIBlue, AlliedGIS and SkyTEM.  XRIBlue, a water exploration and production company has teamed with Allied GIS to process and deliver data that includes detailed geological cross sections and 3D imagery from the very near surface to depths over 350 m. Southern Helicopters, with several years of experience flying SkyTEM systems, will provide the helicopter and pilot. Data acquisition is expected to take place throughout September.

For Immediate Release:  August                                                

Bureau of Reclamation begins low-level helicopter research flights over Yuma area

YUMA, Ariz. — Reclamation’s Yuma Area Office (YAO), in accordance with Federal Aviation Administration regulations, is announcing an upcoming research project involving low-level helicopter flights in the Yuma area. The helicopter will be towing a large hexagonal frame over the Yuma agricultural production areas and the Colorado River over the next few weeks to survey and capture groundwater imagery. The flights will begin the last week of August and continue for up to 3 weeks.

On August 8, 2016 YAO entered into a contract with SkyTEM to collect real-time airborne electromagnetic geophysical survey flow imagery to determine the amount, location, quality and breadth of groundwater existing in underground channels and aquifers in the area. The instrumentation mounted below the helicopter gathers geologic measurements to learn more about water quality and the extent of aquifers existing below the sub-surface layer.

As part of the research effort, the contract helicopter will fly repetitive survey and grid runs over the Yuma Mesa, Yuma Irrigation District, Gila River, Wellton Mohawk, and along the southerly border with Mexico.

As part of its primary mission, YAO monitors and manages the depth and concentration of groundwater levels in the Yuma area for the use and benefit of water districts who depend on these supplies from the Colorado and Gila Rivers for irrigation, municipal use, or other related purposes. To better meet current and future water use needs in the area, YAO is undertaking a groundwater resource characterization study throughout the greater Yuma vicinity.

In conducting the detailed research, technicians will affix electromagnetic based survey equipment to a hexagon-shaped support apparatus that is towed about 100 feet below the helicopter in a ‘spider web’ array that is designed to map geologic features beneath the earth. The helicopter will be staffed by experienced pilots specially trained for low-level flights using this type of equipment.

Data gathered from the research flights will help YAO better understand and manage groundwater resources, and will include detailed geological cross sections and 3D imagery from the very near surface to depths over 350 meters. Data acquisition is expected to take place throughout September.

ENWRA continues to employ SkyTEM method to map aquifers

SkyTEM is happy to announce that we are again working with Eastern Nebraska Water Resources Assessment (ENWRA) in their multi-year programme to map groundwater resources in the State.  Several Natural Resource Districts (NRDs) have joined together to take advantage of the SkyTEM system and each has planned a mix of survey goals. SkyTEM is a helicopter-borne geophysical system capable of mapping subtle changes in geology from the very near surface to depths over 500 m.

See www.enwra.org for a map of the areas being studies as well as to download ENWRA – Introduction to a Hydrogeological Study for details on ENWRA’s projects and goals and approach to groundwater management.

ENWRA

In 2006 the NRDs determined that careful management of all aquifers, even those not directly connected to surface water, are important because the localized and hydrogeologically-complex nature of many aquifers in eastern Nebraska makes them susceptible to overdevelopment and depletion. The ultimate goal of ENWRA is to develop a three-dimensional geologic framework for all of eastern that can be used to determine location, depth to and volume of aquifers. ENWRA worked with the U.S. Geological Survey to assess geophysical tools for their applicability in mapping buried aquifers under deep layers of glacial till as found in parts of Nebraska. SkyTEM is pleased to have been selected for this year’s projects, and for all the previous years ENWRA has employed our unique technology.

The SkyTEM method, specifically developed to map buried aquifers, is widely accepted globally as the principal technique for mapping water resources. SkyTEM is an innovative and technologically advanced airborne geophysical system capable of mapping the top 500 metres of the Earth in fine detail and in 3 dimensions. It was conceived and engineered in Denmark, a country with a reputation for environmental care and R&D. SkyTEM has helped geological organizations and government water agencies on seven continents unearth a wealth of information about their aquifers and aided in their understanding of how geology and mankind can affect, and be affected by, groundwater resources. The SkyTEM method has mapped water resources on a Galapagos Island, important agricultural areas in the USA, Australia, Africa and India, islands in the Caribbean and Indian Ocean and even Antarctica. Recognized for its ability to quickly and accurately map geology in fine detail, the SkyTEM method is also employed globally for mineral and oil & gas exploration as well as environmental and engineering investigations.

Danish water technology in White House summit

SkyTEM Waterville

On 22 March Barack Obama invited to the summit “Moonshot for Water” in connection with the World Water Day in the White House, Washington DC. The participants were more than 200 decision-makers from the President’s office, federal, state and local offices as well as NGOs and Universities.

The US is facing challenges on drought and unnecessary water of water resources. Over the years to come, billion-dollar investments will have to be made to reduce the Americans’ water and energy consumption. Together with a handful of Danish water technology businesses, the SkyTEM technology was part of a consortium of Danish water expertise.

The solutions were presented in a Lego model of a town named Waterville built of 20,000 Lego blocks with a 1.5m tall skyscraper, water supply, wastewater treatment plan and a SkyTEM frame hooked under a hoovering helicopter.

SkyTEM improves chances of finding water in drought stricken California

SkyTEM mapping water in California

SkyTEM began mapping aquifers in the Central Valley of California as well as Barstow area earlier this year. The SkyTEM508 system has now returned to continue mapping farm lands in the Central Valley.

A recent groundwater mapping project in Australia showed that drilling alone is a hit-and-miss technique in which there is just a one-in-five chance of finding water and even less chance of finding water of suitable quality. SkyTEM’s accurate high resolution data has been used to improve the success rate to better than 1 in 3.
