BonTerra Assays as High as 44.80 g/t Gold in Quebec

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 21, 2011) - BonTerra Resources Inc. (TSX VENTURE:BTR) (FRANKFURT:9BR) (the "Company", "BonTerra") has received assays for three (3) drill holes from the 2011 drill program on its Eastern Extension property (the "Property").

The highlight of these drill holes is BA-11-32. This drill hole demonstrated persistent gold mineralization present in a series of mineralized quartz veins. Two of the mineralized veins host visible gold.

Notable in hole BA-11-32 is the presence of three distinct high grade veins. The best samples for these three vein systems range from 11.25 grams/tonne ("g/t") gold in the upper most vein, 15.25 g/t in the middle vein and 44.80 g/t gold in the deepest vein. The sample with the highest gold grade is in the deepest of these three veins. BonTerra is now awaiting the final lab samples from the 2011 drill campaign and is aggressively working on a new NI 43-101 inferred resource calculation.

The Company is currently awaiting a budget for the upcoming 2012 winter drill program which will benefit the Company to drill perpendicularly into the large magnetic high under Lac Barry, the Peninsula Zone discovered by BA-11-06. To date the Company has drilled four holes from the shore to hit this area. Drilling on the ice will enable BonTerra to both drill shorter holes as well as to determine the true widths of the veins which combine to form the Peninsula Zone.

Significant gold assays are outlined in table 1. Table 2 outlines the collar details of the three (3) drill holes disclosed in this news release.

Mitchell Adam, President states, "We invite shareholders and all interested to visit us in the core shack and view some of our core bearing high grade gold at the Quebec City Exploration Conference November 21-24."

Geological Characteristics of the Gold Bearing Veins on the Eastern Extension

The target for all drilling on the Eastern Extension property is smoky quartz veins mineralized with sulphides (pyrite, pyrrhotite, chalcopyrite, sphalerite ± visible gold). Sulphides commonly compose 1-10% of the mineralized zones and can be as high as 50% locally. Alteration is most commonly silica, carbonate, chlorite, tourmaline, sericite and epidote. The combination of quartz veins, tourmaline, alteration types and sulphides is ideal for gold mineralization in the area. Sphalerite present in the quartz veins appears to be associated with the highest grade gold zones on the Property to date.

This technical content of this press release has been reviewed and accepted by Thomas Clarke, Pr.Sci.Nat., a Director of BonTerra. Mr. Clarke is a Qualified Person under NI 43-101.

These are sample results, taken from mineralized intervals of the drill holes. Depths and lengths are core lengths and not true widths. Gold intercepts disclosed in this news release are significant gold intercepts and not all the samples submitted for fire assay. Samples were submitted to ALS Laboratories ("ALS") of Val d'Or, Quebec and AGAT Laboratories ("AGAT") in Sudbury, Ontario for crushing, pulverizing and fire-assay for gold. Samples fire-assaying greater than 10 grams per tonne gold are then fire-assayed with a gravimetric finish to establish the gold grade. Assay samples are taken from drill core, sawed in half along the core axis. One half is sent to ALS and AGAT and the other half retained by the Company for future reference. The Company applies a full quality assurance and quality control program (QAQC) system for every batch of samples submitted to the lab (gold standard, sample duplicate and blank).

Description of the Drill Targets

BA-11-32 was drilled along the section of BA-10-02 in order to validate gold mineralization at approximately 525 metres in vertical depth. BA-11-33 was drilled on section BA-11-10 to validate gold mineralization at a vertical depth of 360 metres. BA-11-34 was drilled on the far eastern section (BA-11-27) to validate gold mineralization at 420 metres vertical depth. This azimuth of this drill hole deviated which led BonTerra to abandon this hole and drill a second hole next to it, BA-11-34A.
