Bonterra Resources Inc. announced that the 2018 winter drilling program is underway at the Gladiator Gold Project. After completing more than 60,000 meters in 2017, the company plans to drill 30,000 meters during the winter drill program and more than 70,000 meters in 2018. The winter drilling program includes mobilizing two additional diamond drills, for a total of six on the project. The expanded program will include four drills, focused on the extension and definition of the Gladiator Gold Deposit. Approximately 20% of the planned meters will be drilled outside of the deposit, at targets highlighted from exploration activities conducted in 2017. Similarly, multiple target areas have been identified to the east and west of the Gladiator Gold Deposit. Additional meters will also be allocated for exploration drilling, pending success in the initial phase of the campaign. The winter drilling program further includes the first metallurgical testing to be completed at the Gladiator Gold Deposit. Results from the metallurgical study are expected in the second quarter of 2018. The updated resource estimate will include more than 100,000 meters of additional drilling since the existing resource was completed in 2012.
