Upper Darling Floodplain SkyTEM airborne EM survey

Geoscience Australia is pleased to announce the completion of the acquisition for the Upper Darling Floodplain airborne electromagnetic (AEM) survey, in 2022 (Figure 3). Covering an area almost half the size of Tasmania with 25,000 line km of high-resolution data, the survey results will provide unprecedented detail of the top 300 m of ground for groundwater and salinity mapping investigations across the floodplain. Data from the survey will be released in late August 2022.

The survey was flown by SkyTEM Australia Pty Ltd using their helicopter-based system. The program was acquired without safety incidences or significant stakeholder engagement issues over a 3-month period.

Eskay Mining discovery following SkyTEM Survey

Eskay Mining Discovers Two New Large VMS Systems at its consolidated Eskay Project. The exploration has discovered two new potentially large volcanogenic massive sulphide (“VMS”) systems on its Consolidated Eskay precious metal project in the Golden Triangle, British Columbia, Canada.

Drilling over the next few weeks will target SkyTEM anomalies suspected to be new occurences and extensions of sulphide mineralization promixal to these targets.

Importantly, the SkyTEM survey includes the Okiep Copper Project area, located 570km north of Cape Town in the Northern Cape Province of South Africa, which is currently under option to Orion.

Okiep Copper Project
The combined Council for Geosciences (CGS) and Orion field teams have confirmed that the recently announced SkyTEM survey has commenced. The regional survey will cover an area of approximately 1,827 km2, with approximately 1,073 line kms flown at 1km line spacing. Orion’s focussed exploration area of approximately 857km2 will have 6,157 line kms flown at 150m line spacing.

AEM surveys will assist groundwater management in California

The California Department of Water Resources has selected a team of consultants led by Ramboll to conduct airborne electromagnetic surveys in California’s high- and medium-priority groundwater basins. The surveys will provide a standardized statewide dataset which will improve understanding of large-scale aquifer structures and support implementation of the Sustainable Groundwater Management Act.

Groundwater is a critical source of water for both California farms and communities. The State of California enacted the Sustainable Groundwater Management Act which requires local agencies in high- and medium-priority groundwater basins to develop and implement groundwater sustainability plans.

To assist local agencies as they develop these plans, the California Department of Water Resources (DWR) will conduct airborne electromagnetic (AEM) surveys in California’s high- and medium-priority groundwater basins. The project will generate coarse-grid subsurface maps that provide framework information about large-scale aquifer structure. The AEM data supports the development or refinement of hydrogeologic conceptual models as well as helps to identify possible areas for recharging groundwater.

“Statewide AEM surveys will further DWR’s technical assistance services supporting local communities as they work to manage their groundwater supply to ensure its reliability,” said Steven Springhorn, acting DWR deputy director of statewide groundwater management.

“AEM data will give locals a better understanding of their groundwater basins and will provide a dataset that supports the overall implementation of SGMA and groundwater sustainability agencies’ development of groundwater sustainability plans.”

Taking an MRI of the ground’s subsurface
During an AEM survey, a helicopter tows electronic equipment that transmits radio waves to the ground and measures the response that returns. The process has been compared to taking an MRI of the ground’s subsurface, and the data collected is used to create continuous images that are interpreted for underground geology to a depth of about 1,000 feet.

The surveys are funded by voter-approved Proposition 68, Senate Bill 5, and the General Fund. The AEM project is expected to start this summer and DWR will hold a public webinar in advance to launch the project.

Local team with global knowledge
DWR has selected Ramboll, a consulting engineering group, to lead the team conducting the surveys and interpretating the data. Along with Ramboll, the team consists of GEI, a consulting engineering and environmental firm with five locations in California, and SkyTEM which will provide the AEM field survey.

“We are proud to support the implementation of the Sustainable Groundwater Management Act by providing high-quality data. With proven technology and solid experience from similar projects, we look forward to the exciting collaboration with DWR, the groundwater sustainability agencies as well as the people in California,” says Jeff Rogers, Director, Ramboll Water in the US.

The helicopter services needed for the AEM Survey are provided by Sinton Helicopters, located in in Paso Robles, California, and Aarhus University from Denmark will provide specialized academic expertise.

Ramboll and SkyTEM have previously conducted similar surveys in California as well as in other countries including Denmark, where the technology has been used to create detailed mapping of the country’s groundwater resources.

Rewarding collaboration
Denmark and California are sharing knowledge through the Danish Water Technology Alliance (WTA) where Ramboll and SkyTEM are participating. The 9th of March, Denmark and California took the next joint step on the way toward a more resilient, sustainable, and efficient water sector by signing a new Memorandum of Understanding.

“It is a great pleasure to hear that Danish expertise and technology will be a part of the Californian efforts related to sustainable groundwater management. In times of transition, international partnerships and knowledge sharing are essential. Therefore, we are very excited to be strengthening our collaboration with California and taking a joint step towards a climate-friendly water sector through the MoU we recently signed,” says Lone Dencker Wisborg, Ambassador of Denmark to the US.

SkyTEM finding drinking water with Airbus helicopters

30% of drinking water (fresh non-salty water) remains under the ground, while 68% is in a frozen state and only 2% is available as surface water. As our available fresh water becomes increasingly scarce and valuable, many are calling groundwater the new oil. Helicopters can help to find it.

Airbus is a manufacturer of helicopters used for many purposes all over the world, also by SkyTEM. Read the story about how SkyTEM employs helicopters to find drinking water in Airbus’ newsroom here: Finding drinking water from above – Helicopters – Airbus

SkyTEM data contributes towards the first geological map in an Aboriginal language

Image by Energymining.sa.gov.au

“The Department for Energy and Mining (DEM) [of South Australia] is proud to publish a geological map in an Aboriginal language for the first time.

The recently released palaeovalley map of the Anangu Pitjantjatjara Yankunytjatjara (APY) Lands, South Australia, has been translated into Pitjantjatjara by the Iwiri Aboriginal Corporation. This broadscale map serves as a guide for more detailed future hydrogeological investigation to unlock additional groundwater resources.”

“The translated map aligns with DEM’s commitment to ensure Aboriginal people can participate fully in the energy and mining sectors, and to support their communities’ aspirations for a positive future.”
