The Barry project is located in the Urban-Barry mining camp 110 km east of the city of Lebel-sur-Quévillon in Québec. The region has been the focus of significant exploration activity including the ongoing 800,000 metre drill program at Osisko Mining’s Windfall project, adjacent to the Barry property.
The Barry deposit is structurally controlled with gold mineralization contained in a system of veins associated with sheared zones included in a wide deformation corridor. Mineralization has been identified 1,300 metres along strike and to 600 metres at depth and coincides with strong IP anomalies occurring in volcanic units throughout the property. The deposit remains open in all directions.
Bonterra is developing an underground ramp and plans to mine ore from Barry and the nearby Moroy and Gladiator deposits to feed the Urban-Barry mill. The mill’s processing capacity is being expanded to 2,400 tpd and Barry is expected to contribute 900 tpd of mill feed at an average grade of 7.0 g/t gold for annual production of about 72,000 ounces of gold. Initial production is expected during the second half of 2019.
In May 2019, Bonterra reported a Mineral Resource Estimate of 2.1 Mt at a grade of 5.8 g/t gold containing 385 kozs of gold in the Indicated category, and an Inferred Resource of 2.7 Mt at a grade of 5.1 g/t gold containing 453 kozs of gold (cut-off grade of 3.5 g/t gold).
Bonterra announced results from a recently completed underground drilling campaign. The diamond drilling campaign consisted of 25 drill holes totaling 7,548 metres during the fourth quarter of 2018 and first quarter of 2019. The definition drilling has confirmed the location and grade of the gold-bearing zones at Barry and will be used for the planning of a proposed bulk sample in the coming months.
- BR18-03: 13.4 g/t gold over 3.2 metres from 307.4 metres;
- BR18-05: 8.2 g/t gold over 5.3 metres from 278.2 metres;
- BR18-08: 15.4 g/t gold over 2.3 metres from 343.9 metres;
- BR18-12B: 157.6 g/t gold over 1.3 metres from 231.1 metres; and
- BR19-25: 15.5 g/t gold over 4.5 metres from 194.8 metres
Bonterra announced a C$20 million private placement to finance the Urban-Barry mill expansion and for continued development and exploration at Barry and their other projects in Québec.
In preparation for the bulk sample program and access to underground drill bays, the development of the Barry ramp is progressing and on schedule with approximately 130 metres completed.
