The West Arena property lies near the middle of the Urban-Barry Greenstone Belt, approximately 170 km northeast of Val-d’Or, Québec. The property contains the Gladiator gold deposit where Bonterra’s exploration programs have been focused. Gladiator is described as a highly silicified and altered sheared mafic volcanic, locally exhibiting intrusions of syenite and quartz porphyry. Gold is found primarily in smokey quartzcarbonate and tourmaline veins ranging from 20 centimetres to 4 metres in width.
An Inferred Resource estimate was published for Gladiator in 2012 and contains 905 kt grading 9.4 g/t for 273,000 ounces of gold (4.0 g/t cut-off ). A 60,000 metre drill campaign completed during 2017 and a 70,000 metre program in 2018 has expanded the strike length and depth of the Gladiator deposit to 1,300 metres and 1,100 metres respectively, with a number of subparallel zones or mineralized horizons being identified. The deposit remains open in all directions and an updated Mineral Resource estimate is expected to be released during 2018.
Bonterra has initiated the permitting process for the development of a decline to complete a bulk sample at Gladiator. The project is expected to contribute 1,000 tpd of gold ore to the Urban-Barry mill, a nearby processing plant that is being expanded to handle throughput of 2,400 tpd. Mining is expected to commence at Gladiator during the second half of 2020.
A mineral resource estimate is expected during the fourth quarter of 2018. Drilling will continue at the deposit as Bonterra sees significant exploration potential.
Ongoing resource development drilling has extended mineralization along multiple zones at Gladiator. Results include 15.3 g/t gold over 2.7 metres from 781.0 metres and 30.5 g/t gold over 2.0 metres from 555.0 metres.
Infill drill results are demonstrating the continuity of the Gladiator deposit and the predictability of the mineralized zones. Assay results include 44.9 g/t gold over 3.0 metres from 337.0 metres and 34.3 g/t gold over 2.8 metres from 274.2 metres.
