With the completion of NASA´s IceBridge campaign for another year, mission scientists are eager to compile all the data gathered over the 115 hours of survey flying.  Sander Geophysics´ is in the midst of processing all the AIRGrav data collected.  The IceBridge research team has found definite changes since the last mission flown in October and November 2009.  The initial data is showing bottom crevasses that could be hundreds of meters tall, starting at the bottom of the ice shelves.  Continuous measurements over the years to come will reveal the responses of glaciers and ice sheets to the changing climate.

NASA´s IceBridge campaign which employs Sander Geophysics´ AIRGrav have completed another successful year collecting data over Antarctica.  Adverse weather hindered progress this season although NASA was able to fly 10 successful missions making use of 84% of the allocated science flight hours.  Every ICESat orbit ever completed has been flown with the DC-8 around the South Pole.  The next mission will be over the Arctic Ocean with NASA´s P-3B aircraft in March 2011.

October 2010

Sander Geophysics´ AIRGrav returns to Antarctica.  NASA´s Operation IceBridge mission is set to begin its second year with scientists returning to the Southern Hemisphere this week, to continue airborne surveys over Antarctica.  The mission involves monitoring the region´s changing sea ice, ice sheets and glaciers.  The flights will again be made from Punta Arenas, Chile, on NASA´s DC-8, a 157-foot airborne laboratory equipped with a suite of seven instruments, including an AIRGrav system to record the gravity field.  According to NASA, the focus of the project is to re-survey areas that are undergoing rapid change and fly some new lines in other areas of interest.

A program of drilling and concurrent ground geophysical surveys is underway on the mineral concession and prospecting permits held by Darnley Bay Resources Limited (DBR) in the Paulatuk NWT area.  DBR reports that the ground gravity surveys have confirmed the targets located from the AIRGrav airborne gravity survey flown by Sander Geophysics.  According to DBR, the focus is on locating deposits related to the mafic/ultramafic intrusion interpreted to be the source of the 132 mGal Darnley Bay gravity anomaly.

August 2010

Darnley Bay's exploration and drill targets for base metals, were prepared from analysis and modelling of the recently completed gravity, electromagnetic and magnetic surveys flown over a large portion of its properties near Paulatuk, NT.  In order to make 3D models from the data, to ascertain the shape of the anomaly source at depths of economic interest, higher resolution gravity data were required.  SGL's AIRGrav data provided the improved resolution and detail necessary to target the drilling program.

Geoscience BC´s QUEST-South project builds on the successful QUEST and QUEST-West exploration projects. QUEST-South is focused on the Quesnel Terrane, south of Williams Lake.  Phase 1 of the QUEST-South project involved regional geochemical and airborne gravity surveys over the area.  The airborne gravity survey was undertaken by Sander Geophysics using their airborne inertially referenced gravimeter (AIRGrav).  Phase 2 of the project involves adding value to the regional datasets, integrating all available data for the QUEST-South area and, where necessary, the acquisition of additional new data.  This phase of the project may include geophysical and geochemical modelling, deposit specific studies, data compilations, mapping and other research oriented studies all aimed at providing industry with new geoscience information to help target exploration efforts.

During March-April 2010 NunaMinerals conducted a 3,955 line-kilometre combined magnetic and radiometric survey within the company´s Tikiusaaq licence.  The helicopter-borne surveys were flown by Sander Geophysics with a line spacing of 100 metres.  The magnetic survey confirms the extent of the carbonatite core.  Thorium anomalies reveal the prospectivity for Rare Earth Elements (REEs) associated with the Tikiusaaq carbonatite.

Sander Geophysics has taken delivery of a de Havilland DHC-6 300 Twin Otter survey aircraft to support continued high demand for SGL´s airborne geophysical services.  Formerly operated by the Geological Survey of Finland (GTK) and the British Geological Survey (BGS), the aircraft comes equipped with a frequency-domain electromagnetic system, a stinger mounted magnetometer, and a radiometric system.  This 3-in-1 system has been used extensively in Europe and Africa to produce excellent quality very high resolution geophysical data.  The addition of SGL's industry leading AIRGrav airborne gravity system will provide a unique suite of geophysical survey systems for mineral and petroleum exploration.  The aircraft is especially well suited to harsh environments where a twin turbine aircraft is preferable, such as offshore arctic surveys.

April 2010

Sander Geophysics is very pleased to have been selected once again to operate the AIRGrav system for NASA's Operation IceBridge (http://www.espo.nasa.gov/oib/). Designed to monitor ice at the Earth's poles, IceBridge has moved to the northern hemisphere this spring for flights over Greenland and the Arctic Ocean.  SGL's AIRGrav is working alongside laser scanner, ice and snow radar science teams.  The flights this spring will be split between the NASA DC-8 from the Dryden Airborne Operations Facility and the P-3 from the Wallops Flight Facility.  Missions are being flown from Thule and Kangerlussuaq in Greenland in March, April, and May.

April 2010

Darnely Bay Resources Limited unveils preliminary data gathered this spring over and around the Darnley Bay Anomaly.  Sander Geophysics completed the helicopter-borne AIRGrav and magnetic survey of the block on April 3rd.  The airborne gravity data reveals considerable improvement in resolution over the previously collected ground gravity data.  While the data is preliminary and more work will be done to improve data resolution and remove topographic effects a new wealth of geological information is apparent.  These data sources will greatly aid in selecting drill targets and also sample sites for mineralized zones on the surface.  When the data is finalized further analysis and modeling will take place.

April 2010

Sander Geophysics has been awarded a contract by LNG Energy Ltd. to conduct a high resolution gravity and magnetic fixed-wing survey totalling over 25,000 lkm of flying.  This project encompasses LNG Energy's licenses in southern and northern Papua New Guinea.

Sander Geophysics' helicopter helps rescue three polar bear hunters trapped on an ice floe east of Paulatuk, NT, in the Canadian Arctic.  The hunters were stranded all night when the ice pan they were on broke free several kilometres from shore resulting in one of their snowmobiles falling off the edge of the ice.  A SPOT satellite GPS device was used to send a 911 call to a dispatch centre, which then notified the local police.  Sander Geophysics currently has a helicopter based in Paulatuk, conducting an airborne geophysical survey for Darnley Bay Resources (see http://www.sgl.com/news/Darnley_Bay-230210.pdf).  SGL's helicopter pilot Brian Simms was awoken by a knock at the door at 2 am requesting his assistance in rescuing the stranded hunters.  After preparing for the flight and fueling SGL's Eurocopter B3 helicopter, Brian Simms and another pilot in a second helicopter safely rescued the hunters from the ice.

March 2010

NunaMinerals has extended its exclusive exploration license from 247 km² to 1,342 km² covering the most prospective ground for iron around the magnetic high at Inglefield Land, northern Greenland.  Sander Geophysics has been awarded the combined gravity and magnetic survey of approximately 10,000 line kilometers over the area.  The data gathered will provide a better estimate of the potential of the Minturn magnetite body.  The survey will be conducted from a base in the town of Qaanaaq (formerly Thule) situated 100 km south of Inglefield Land.

Sander Geophysics has been awarded a contract by Darnley Bay Resources Limited to fly a 5,980 line km airborne gravity and magnetic survey over the Darnley Bay Gravity Anomaly.  The purpose of the survey is to significantly improve the resolution of the previous ground gravity surveys over the area and to locate targets for drilling.

January 2010

Geoscience BC released the final data set for the QUEST-South airborne gravity survey that was flown by Sander Geophysics in the fall of 2009.  The airborne gravity digital data, grids and final technical report can be downloaded at Geoscience BC QUEST Project Data Releases.  This gravity survey involved more than 25,000 line kilometers of data at a 2 km line spacing.
