Bonterra Resources Inc. (TSX-V: BTR) (US: BONXF) (FSE: 9BR1) is pleased to announce recent exploration activities located west of the Gladiator Deposit and within the extensive Coliseum Property have led to the discovery of a new gold and silver bearing horizon. The discovery located approximately 4 km to the south west of the Gladiator Deposit, was highlighted by recent drill hole CL-17-14, which intersected 4.7 g/t Au and 44.6 g/t Ag over 2.7 m at a depth of 250 m below surface. The Bonterra technical team considers this newly discovered zone to be an extension of the Gladiator mineralized trend.

Key Highlights:

• Hole CL-17-14 discovery of new mineralized zone (Temica Gold Zone) with an intersection of 4.7 g/t Au and 44.6 g/t Ag over 2.7 m at 250 m below surface. This drill hole is located over 4 km to the south west of the Gladiator deposit.
  • Drill hole 17-14 returned 44.6 g/t Ag with the presence of galena as additional sulphide mineralization.
• Hole CL-17-06 intersects new mineralized zone (Temica Gold Zone) with an intersection of 13.0 g/t Au over 1.0 m at 200 m below surface, and located over 5 km to the south west of the Gladiator Gold Deposit.
• Hole CL-17-01 also intersected the Temica Zone near surface with close proximity to drill hole CL-17-14, but was located too close to the zone and resulted in a partial intersection.
• Three drill holes now exist in the Temica Zone over a 1 km length as described above.
• The previously completed till sampling and induced polarization surveys led to the drilling and discovery of the Temica Zone. Further drilling will be conducted on additional targets and identified trends as well as on the Temica Zone.
• Both CL-17-06 and CL-17-14 intersected shear zone hosted mineralized quartz-carbonate veining with pyrite and sphalerite.

• Stated lengths are core width as drilled, true widths vary and average between 60 and 80 percent of drilled widths. Core axis angles of the intersection contacts and surrounding rock units average 55 to 70 degrees.

Please see the surface plan map (http://www.bonterraresources.com/en/gladiator/maps-sections) showing the locations of the new Temica Gold Zone drill holes and other targets relative to the location of the Gladiator Gold Deposit. The resource development drill program at the Gladiator Gold Deposit continues to focus on extending the known gold zones, with attention on the new, additional discovered gold zones located to the north and south of the initial Gladiator gold veins.
