BonTerra Resources Inc.: Fugro Commences Airborne Magnetic Survey of the Symphony Property in British Columbia
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 09/22/11 -- BonTerra Resources Inc. (TSX VENTURE: BTR) (FRANKFURT: 9BR) (the 'Company', 'BonTerra') Fugro Airborne Surveys has commenced an aeromagnetic survey over the entire Symphony Property (the 'Property'). The Property is situated in the Omineca mining division approximately 29 kilometres southwest of Houston, British Columbia. The Property is accessed by a well-maintained forestry road that is situated just east of Owen Lake. The Property comprises one contiguous block of claims totaling 2975 hectares. BonTerra recently staked additional claims to consolidate its land position situated in between the Silver Queen Mine to the south and the Silver Streak property to the north.
Directly bordering the Property to the south is the past producing Silver Queen Mine. Historical ore grades are 8.72 opt (299 grams / tonne) silver, 0.18 opt (6.17 g/t) gold, 6.73% zinc, 1.16% lead, and 0.47% copper.
The Silver Queen property is currently being advanced by New Nadina Explorations. New Nadina has intersected silver, gold and base metal mineralization on the property. They have completed an aeromagnetic and ZTEM survey, a titan geophysical survey and diamond drilling. Drilling revealed grades of up to 493.5 g/t silver, 5.06 g/t gold, 13.5% zinc, 6% lead and 2.88% copper. The mineralized trend has a general southeast to northwest trend, the direction towards which the Property is situated.
The Silver Streak property is situated to the north of the Property. Trenching on the Silver Streak identified significant mineralization which included 1.99% Cu and 338 g/t Ag over 33 meters. An inclined diamond drill hole was drilled underneath this trench in 1991. A zone grading 8.8 meters of 0.49% copper and 258 g/t silver, within 21.1 meters averaging 0.27% copper and 127 g/t silver was discovered. Another trench excavated in 2002 graded 0.26% copper and 1.91 g/t Ag over 16.7 meters. The mineralized zone is believed to have a NW-SE strike, the general direction of the Property.
This DIGHEM Electromagnetic survey with optional Radiometrics will total 308 line kilometres of readings. DIGHEM records magnetic data to measure the earth's magnetic field which can be interpreted to show changes in bedrock geology to great depth. The system uses multiple frequency electromagnetic fields to measure and map electrical conductivity in three dimensions. The DIGHEM EM system provides the interpretation benefits that can only be realized by a system employing both horizontal coplanar and vertical coaxial transmitter-receiver coil-pairs. BonTerra has selected Fugro's optional Radiometrics application for an effective geological mapping solution as part of this mineral exploration program. The Company plans on using this survey to identify additional targets of interest on the property in its evaluation for silver and base metal mineralization potential on the Property.
Fugro Airborne Surveys is the global leader in providing airborne and ground based geophysical surveys. Fugro collects, processes and interprets geophysical data for clients in the mining, petroleum, engineering and environmental sectors.
