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 contains highly altered, silicified, sheared mafic volcanics, with local intrusions of syenite and quartz porphyry. Gold occurs primarily in smokey quartz-carbonate and tourmaline veins ranging from 20 centimetres to 4 metres in width.
A Mineral Resource Estimate for the Gladiator deposit was published in June 2021 and contains 1.4 Mt grading 8.6 g/t for 391,000 ounces of gold in the Measured & Indicated category (2.6 g/t cut-off). Another 4.2 Mt grading 7.4 g/t gold for 989,000 ounces of gold is listed in the Inferred category. The Resource estimate is based on over 150 vein structures and clusters within seven structural groups.
Bonterra has initiated the permitting process for the development of a decline to complete a bulk sample at Gladiator. The project is being considered for providing 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.
Bonterra intersected 61.7 g/t gold over 0.5 metres in drill hole BA-21-30 from 127.3 metres in the ongoing expansion drilling at Gladiator. The drilling program continues to extend the size of the mineralization. Recent data shows possible higher density of veining to the South of the existing Gladiator 2021 mineral resource. In addition, work on the Preliminary Economic Assessment, which would utilize the existing Bachelor Mill as a central processing facility, is ongoing and expected to be complete in Q4 2021.
A 16,500 metre drill program is underway at Gladiator focused on expanding the size and scope of the project, as well as improving the grade continuity for the upcoming Mineral Resources Estimate update.
