Bonterra Resources Inc.: Phase Iii Drilling Is Underway on the Eastern Extension & Bonterra Completes the First Five Drill Holes on the Ice

VANCOUVER, BRITISH COLUMBIA -- (Marketwire - March 15, 2012) - BonTerra Resources Inc. (TSX VENTURE: BTR) (FRANKFURT: 9BR) (the "Company", "BonTerra") continues drilling on its Eastern Extension property (the "Property") which is situated approximately 170 kilometres northeast of Val d'Or, Quebec. To date, BonTerra has completed five drill holes on the ice. Samples from these holes are being sent to AGAT Labs to be assayed for gold. These drill holes targeted the series of five mineralized veins that management believes run across the Property. Consistent with previously reported samples, the field geologist has advised the Company that visible gold was observed in the quartz vein samples. BonTerra has not yet been able to confirm this although, as disclosed on numerous occasions, visible gold has been present in prior samples from the Property's mineralized veins.

There are three primary goals of the Phase III Drill Program. The first being to strategically drill as many holes on the ice as possible to grow the size and potential of the mineralized zone of the Peninsula Zone, a zone characterized by a high to very high magnetic signature. The second focus is to drill the Rivage Zone, a vein discovered by BonTerra as a chip sample assayed 204 g/t gold and attempt to establish a link with the Peninsula Zone. Thirdly is carrying out additional drilling activities to establish an increased mineralized zone.

Last year BonTerra drilled a series of deep holes (as deep as 708 metres) to increase the mineralized zone for the pending NI 43-101 compliant gold resource calculation (the "Calculation"). It is now the intent of the Company to focus on strike extension followed up by infill drilling.

In order to ensure a timely completion of the Calculation, this third phase of drilling will not be integrated into the Calculation. Instead, management intends to add these new holes at a later date into an updated resource calculation once drilling this series of primary drill targets on and off the ice is completed in the future.

Nav Dhaliwal, President states, "We are very pleased to have closed our private placement with an overwhelming response in this challenging market. The Company is very enthusiastic about getting on the ice this winter. The information from this will be invaluable to understanding the geology and structure as well as to grow the mineralized zone containing the high grade gold bearing veins on the Property. The continued success of this program demonstrates the professionalism of our team."
