Moroy and Bachelor are greenstone hosted, structurally controlled alkalic-magmatic gold deposits located outside of Val d’Or, Québec. The property was host to a producing mine during the 1980’s and in 2004 underwent major upgrades to the existing mine and mill infrastructure including the installation of a carbon-in-pulp process plant.
The Bachelor mine reached commercial production in 2013 as a long-hole underground operation and the mined ore is processed at the Urban-Barry mill. The mill has a capacity of 800 tpd and has produced more than 210,000 ozs of gold since its commissioning. Gold recoveries have averaged between 96% and 98%. Bonterra plans to expand the Urban-Barry mill to increase its processing capacity to 2,400 tpd in order to accommodate ore from Moroy, Bachelor and Bonterra´s nearby Barry and Gladiator deposits.
The Moroy deposit is sub-parallel and south of the Bachelor deposit, dipping north towards the Bachelor trend. Development and drill programs are underway with more than 65,000 metres of surface and underground drilling completed to date. A Mineral Resource Estimate for Moroy was published in May 2019 and contains 667 kt grading 5.17 g/t for 111,000 ounces of gold in the Measured and Indicated category and 396 kt grading 4.32 g/t for 55,000 ounces of gold in the Inferred category (3.0 g/t gold cut-off grade).
Bonterra announced a company-wide mineral resource estimate in May 2019 for all Urban Barry exploration assets including the Gladiator, Barry and Moroy deposits. The combined mineral resource estimate is part of Bonterra’s strategy to fast track development of the three deposits simultaneously and to optimize feed to the Urban Barry Mill over the life of the three mines.
Exploration continues at the Moroy deposit and drilling has extended the known mineralization by 150 metres in the down-plunge direction. Drill-hole MY-19-155 intersected 12.8 g/t gold over 5.6 metres from 256.3 metres and drill-hole MY-19-158 intersected 12.2 g/t gold over 5.4 metres from 70.5 metres. The deposit remains open at depth and along strike.
