Bonterra to idle Bachelor-Moroy underground; Bachelor mill unaffected
However, Bonterra said the status of the assay lab, camp, mill and the tailings management area – together known as the Bachelor mill complex – remains unchanged, and that these assets are key components of the planned restart of production at the Barry open pit project. The permitting process for the mill and tailings management area expansion is still ongoing, and considering the changes at the Bachelor-Moroy deposit, a scope change will be submitted by the company shortly.
In the meantime, Bonterra has released results from an additional 54 holes from the Barry drill program that will included in a new mineral resource estimate in preparation of a pre-feasibility study, which is now underway and expected later this year. Currently, the Barry open pit deposit has measured and indicated resources totalling 1.9 million tonnes grading 2.66 g/t for 165,000 oz. contained gold.
Notable intercepts from the latest drilling include: 1.8 g/t gold over 23.2 metres, including 3.0 g/t gold over 4.0 metres and 11.4 g/t gold over 1.5 metres; 2.5 g/t gold over 10.5 metres including 7.3 g/t gold over 1.6 metres; and 1.0 g/t gold over 37.0 metres including 3.2 g/t gold over 8.6 metres.
“These recent drill results confirm the grade continuity of the near surface mineralization at the Barry deposit and will be used to further refine our geological model as part of the PFS that is expected to be completed by year-end. The PFS is an important milestone in our renewed strategy of advancing the company toward production, starting with the Barry open pit,” Marc André Pelletier, president and CEO of Bonterra, commented.
Additionally, Bonterra announced that it has commenced 125,000 metres of infill drilling on the underground portion of the Barry deposit, which contains 500,000 ounces of measured and indicated resources and 700,000 ounces of inferred resources, as stated in last year’s estimate. The company plans to continue its strategy of moving toward the production restart of the open pit while developing the higher-grade underground mineralization in parallel.
At the nearby Gladiator deposit, one of Bonterra’s main assets, the company has undertaken an exploration drill campaign on barges that was completed as scheduled at the end of July. The geological team will continue working on the mineral resources model and geological interpretation of the deposit as drill results from the campaign become available. The team is also planning a more focused drill program for next year.
