BTR: BonTerra Resources Inc.: Infill Sampling of Ba-10-08 Widens Gold Intercept

VANCOUVER, BRITISH COLUMBIA–(Marketwire – Sept. 9, 2011) – BonTerra Resources Inc. (TSX VENTURE:BTR) (RANKFURT:9BR) (the “Company”, “BonTerra”) has conducted infill sampling on secondary vein systems and zones of interest in BA-10-08 which was disclosed by the company in a news release dated January 12, 2011. This infill sampling has led to a wider gold intercept as shown below and in table 1. The originally disclosed drill intercept is shown in table 2. All of the infill samples have been put into the 3D model and are being added into the gold resource calculation.

Primary Drill Intercepts of BA-10-08

  • 17.50 metres assaying 6.24 g/t gold
  • INCLUDING: 6.0 metres assaying 16.75 g/t gold
  • INCLUDING: 3.0 metres assaying 21.09 g/t gold
  • INCLUDING: 1.0 metres assaying 31.20 g/t gold
  • INCLUDING: 1.0 metres assaying 30.50 g/t gold

Drill BA-10-08 was drilled to the west of the series of initial five drill holes. It was due to the impressive presence of three (3) distinct roughly parallel gold zones in BA-10-08 that led BonTerra to drill further to the southwest still. It was there in the southwest where additional drill holes discovered further high grade gold in BA-11-06. This new gold trap was named the Peninsula Zone.

Mitchell Adam, President states, “Our infill sampling program is leading to BonTerra discovering gold not only in the smoky quartz veins but in the secondary veins too. BonTerra is enthusiastic this is paying dividends by widening pre-existing zones of high grade gold. Every mineralized vein has the potential to add to the number of ounces we are currently working toward defining in Quebec.”

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 and sericite. 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.

The drill program and sampling is being supervised on behalf of the Company by Geologica Inc. of Val d’Or, Quebec. 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 Chemex of Val d’Or, Quebec 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. Assay samples are taken from drill core, sawed in half along the core axis. One half is sent to ALS Chemex Laboratories 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).
