Bonterra begins processing material at Bachelor Mill for bulk sample

Sep 16, 2020

Bonterra Resources Inc. has started processing material at the Bachelor Mill northeast of Val D'Or. In July, the company resumed mining of its 10,000 tonne bulk sample at the Moroy Project. The Moroy project is 900 metres south of the old Bachelor Mine, and the company uses the underground infrastructure of the Bachelor Mine to access the Moroy Project.

In August 2020, the company emptied the old material inventory in the underground muck handling circuit to make room for the material coming from the bulk sample at Moroy. The old material was stockpiled in the silos, and on the ore pad on surface. On September 8, 2020, Bonterra began to process the material stored on surface from the old Bachelor Mine and will continue to process the old material until September 21, 2020.

On September 29, 2020, the Company plans to start processing the material from the bulk sample at Moroy and expects to complete the bulk sample around the end of October 2020. An independent consulting engineering firm is supervising the processing of the bulk sample at the Bachelor Mill. The consulting firm will produce a report after the bulk sample is completed. The company will publish the report once available, and it will be incorporated into an eventual preliminary economic assessment.

The bulk sample program at the Moroy project is being undertaken in order to verify the grade continuity within the mineralized structure and reconcile the resource grade to the recovered ounces following processing. The bulk sample is focused on the M1 shear zone on level 11,440 metres ("m") below surface. The M1 structure is sub-vertical and the company plans to extract it via a sub-level long-hole stoping method at 15 m intervals.

Exploration update

In July 2020, the Company announced the beginning of a 56,000 m drill campaign. The Company ramped up the campaign during July and August 2020, and now has seven diamond drill rigs fully staffed active on the projects. There are now six drill rigs between the Moroy, Barry, and Gladiator projects. The seventh drill rig is targeting potential sectors in the Desmaraisville camp just outside the Bachelor/Moroy area. The Company will add an eighth drill rig on regional targets in the Urban-Barry camp before the end of September 2020. 

Pascal Hamelin, Interim CEO and VP, Operations commented: "I'm very happy to see that we have safely ramped up the rigs from zero to seven rigs in 6 weeks. With the selective assaying of the material from the bulk sample expected to be completed by the end of this month, we will be able to switch our assay lab's focus to our cut drill core assay backlog and release those results when available."
