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. |
||||
|
|
August 2010 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. |

July 2010 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. |

June 2010 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.

March 2010 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. |

December 2009 Rugged mountains buried beneath the ice of Antarctica have
been imaged with the help of Sander Geophysics' AIRGrav airborne gravity system. During December 2008 and January 2009 over 50,000 km
of airborne gravity data were collected by one of SGL's AIRGrav systems mounted in a Twin Otter aircraft as part of Antarctica's
Gamburtsev Province Project (AGAP). Dr Michael Studinger from the Lamont-Doherty Earth Observatory (LDEO) of Columbia
University, New York, presented preliminary results from the AGAP survey at the 2009 American Geophysical Union (AGU)
meeting in San Francisco. |

December 2009 The 2009
ICE Bridge project over Antarctica has wrapped
up successfully. Designed to provide vital information about ice at the poles, ICE Bridge is a NASA project
to bridge the gap between the retirement of ICESat I (2009) and the launch of ICESat II (expected in 2014-15). The
project used a specially modified NASA DC-8 mounted with various pieces of equipment from multiple agencies, including Sander
Geophysics' AIRGrav system. This season, 21 missions were flown over Antarctica from a base in southern Chile,
totalling 155,000 km and 227 flight hours. This exceeded the original plan of a 17 flight mission, with some of
those additional flights designed specifically to take advantage of the high resolution and accuracy of Sander Geophysics'
AIRGrav system. Highlights include the acquisition of detailed gravity maps covering the floating ice shelves
associated with major West Antarctic outlet glaciers, which is expected to contribute to a better understanding of
ice sheet mass balance and its relation to the changes in the polar climate. |

November 2009 To demonstrate the capability of AIRGrav for marine gravity
applications Sander Geophysics performed a marine gravity survey on Lake Ontario in October, 2009. Preliminary results
from the survey are excellent, and the data will be publicly released once final processing has been completed. Sander
Geophysics has been acquiring and processing high resolution airborne gravity data for over 10 years using the company’s 12 AIRGrav
systems. AIRGrav is now the industry standard for high resolution airborne gravity, with over 2 million lkm of airborne
gravity surveys flown worldwide. Designed specifically for the unique characteristics of the airborne environment,
AIRGrav is the highest resolution gravimeter available. The data quality is not affected by the air turbulence normally
encountered on airborne surveys, even in hot and windy environments. The stability of the AIRGrav system also
allows surveys to be flown under normal daytime survey conditions. Until now AIRGrav has been used exclusively for
airborne surveys, but AIRGrav's ability to operate in the harsh airborne environment makes it ideally suited to marine use,
where it can be used in conjunction with seismic or as a standalone survey - AIRGrav is essentially over-engineered for
the less harsh environment of marine surveys, where vibration and vessel acceleration is much lower than in an aircraft. |

October 2009 Sander Geophysics is proud to be participating
in NASA's ICE Bridge project in Antarctica. Having
previously supplied an AIRGrav airborne gravimeter for last year's highly successful AGAP survey in Antarctica, SGL
was the obvious choice to supply a reliable, high resolution, gravity system in support of NASA's current project. The
ICE Bridge project is designed to provide vital information about the ice sheet at the poles, and will
bridge the gap between the retirement of ICESat I (expected in 2009) and the launch of ICESat II (expected in 2014-15). During
this period, NASA plans to acquire data using a DC-8 aircraft mounted with various pieces of equipment from multiple
agencies, including Sander Geophysics' AIRGrav system, which is being provided through an agreement with Lamont-Doherty Earth Observatory
of Columbia University. Missions will be flown over Antarctica from a base in southern Chile starting in October, 2009. |

August 2009
Sander Geophysics will fly a new airborne geophysical survey project under contract to Geoscience BC. The
survey, called QUEST-South, is designed to encourage exploration and create much needed jobs in BC's southern
interior. While the region has significant potential for copper-gold and copper-molybdenum deposits, parts of
the area are obscured by young volcanic rock making exploration more challenging. Sander Geophysics will
use its unique AIRGrav airborne gravity technology to gather information about the subsurface. The survey area
is the size of England, so a vast area is being covered. |
||||
|
|
August 2009
Sander Geophysics is pleased to have been selected by Geoscience BC to fly a new airborne gravity survey in British Columbia,
Canada. This survey, called QUEST-South, will be Sander Geophysics third airborne gravity survey funded by
Geoscience BC in this region. Sander Geophysics will use its unique AIRGrav airborne gravity technology to
fly an area of approximately 45,000 square kilometers between Williams Lake and the US border. The new public
information gathered for the mineral exploration industry is intended to encourage exploration investment and job
opportunities in BC's southern interior. The datasets from the previously flown Geoscience BC surveys
called QUEST (2007) and QUEST-West (2008) are already publicly available, and they will be combined with the new
QUEST-South dataset which is expected to be released in early 2010. |

July 2009
Sander Geophysics' AIRGrav system was chosen for Antarctica's Gamburtsev Province Project over competing
airborne gravimeters due to AIRGrav's superior performance. Before being chosen for the demanding Antarctic
survey test flights were flown over the Rocky Mountains, west of Calgary, and from Ellesmere Island in Nunavut
to demonstrate the system's capabilities at high latitudes over the North Pole, and over Greenland's ice sheet. The
system then headed for Antarctica. The AIRGrav system accurately gathers gravity data while compensating
for aircraft motion due to turbulence, and aircraft vibrations, allowing for the removal of these effects from
the final data during processing, using very accurate GPS. |

|
|
April 2009
The AIRGrav survey flown by SGL in the Nechako Basin was part of a project funded by the
Government of Canada, through Natural Resources Canada’s Mountain Pine Beetle Program. This
stimulation to mineral and energy exploration could help diversify the economy in areas recovering
from mountain pine beetle infestation. Potential oil and gas deposits can be detected by
identifying the varied densities of rock revealed by the airborne gravity survey. |
||||
|
|
March 2009
Sander Geophysics (SGL) successfully completed its participation in the data acquisition phase
of Antarctica's Gamburtsev Province Project (AGAP) which is part of the International Polar Year.
During December and January, over 50,000 km of airborne gravity data were collected by the AIRGrav
system mounted in the survey Twin Otter aircraft. The gravity map revealed the peaks and
valleys of the Gamburtsev mountains hidden beneath the featureless surface of the ice sheet. Data
is currently in Ottawa being analyzed.
