Willoughby Property

Willoughby Property, British Columbia

Target: The exploration target at Willoughby is a high grade lode gold-silver deposit.

Property and Ownership Description: Bonterra has the right to earn an initial 51% interest in the Willoughby property from Copper Ridge Explorations Inc. by paying $25,000, issuing 550,000 shares and completing $1.5 million in exploration work on the property over four years. Bonterra may then increase its interest to 65% by issuing a further 300,000 shares and completing an additional $1.5 million in exploration over the next two years. Bonterra will also be responsible for payments to the underlying property vendor, who will retain the 4% NSR on the property that can be reduced to 1% by payment of $500,000.

Project Description: The Willoughby property is located within a well mineralized trend of the Hazelton Group volcanic rocks in the Stewart-Iskut-Eskay Creek gold district. Highlights of historical drilling on the property include:

• 11.7 m grading 39.8 gpt gold in hole 94-15
• 12.2 m grading 10.8 gpt gold, including 3.0 m grading 32.9 gpt gold in hole 94-27
• 2.9 m grading 398 gpt gold in hole 95-36
• 5.9 m grading 16.2 gpt gold in hole 95-51
• 13.0 m grading 13.3 gpt gold, including 3.0 m grading 31.1 gpt gold in hole 95-53

Other deposits of note within this trend include Red Mountain, 7 kilometres to the west of Willoughby, which has an inferred geologic resource of 1.9 million tonnes of 9.8 g/t gold and 38.1 g/t silver (BC Minfile 103P 086, 1991) and Silbak Premier, 28 kilometres to the northwest of Willoughby, which produced 62.2 million grams (1.99 million ounces) of gold and 1,333 million grams (42.86 million ounces) of silver from 6.6 million tonnes of ore (BC Minfile 104B 054, 1997).

Gold and silver mineralization at Willoughby occurs within andesite volcanics and hornblende feldspar porphyry intrusive rocks. Where mineralized, the rocks have been subject to sericite-carbonate-chlorite-pyrite alteration. To date, eight zones of gold and silver mineralization have been located within a 500 by 1500 m area. Mineralization, consisting of pyrite and pyrrhotite along with minor sphalerite, galena and rare visible gold occurs in veins, stockwork and as fracture fillings. In addition, pyrite and pyrrhotite occur as semi-massive to massive lenses and pods.

Exploration History: Mineralization was first discovered on the Willoughby property in 1941, but the majority of the exploration work on the property was conducted during the period 1994 to 1997, including 90 m of exploration drifting, 2438 m of underground drilling and 6597 m of surface diamond drilling. Much of this work was focused on the North Zone and the Wilby Zone, where several high grade gold and silver intersections were encountered. The structural complexity of the zones made the interpolation and interpretation of the high grade zones difficult. No resource has yet been calculated for the Willoughby Property.

Recent Exploration: Bonterra completed a property examination at Willoughby in August, 2007 and completed a compilation of historical in December, 2007. Late in the 2007 field season, an airborne magnetic and electromagnetic geophysical survey was completed over the property. Some of the conductors detected by this survey correlated with a number of the known mineralized zones. In addition, the survey identified a number of other potentially mineralized conductive trends. A NI 43-101 report has also been completed.

Future Plans: Bonterra plans a drill test of the Willoughby property, as recommended in the 43-101 report and budgeted at $400,000.
