“Today’s high-grade results, highlighted by DZG-SF-26-945, continue to reinforce the strength and continuity of silver mineralization both around the open pit and across the central zone,” said Benoit La Salle, President & CEO. “At the same time, development of the exploration drift at the 1,825-metre level is progressing well, setting the stage for drilling west of the fault to begin in Q4 and providing an important new opportunity to expand the mineralized footprint.”

Quality Assurance

Article content

For core drilling, all individual samples represent approximately one meter in length of core, which is halved. Half of the core is kept on site for reference, and its counterpart is sent for preparation and assaying to African Laboratory for Mining and Environment (“Afrilab”) in Marrakech, Morocco or to ALS Laboratory at the Zgounder Mine site. All samples are analyzed for silver, copper, iron, lead, and zinc using Aqua regia and finished by atomic absorption spectroscopy (“AAS”). Samples grading above 200 g/t Ag are reanalyzed by fire assay.

For definition drilling using RC, all individual samples represent 1.0m in length and for T28 drilling equipment, all individual samples represent 1.2m in length. Samples are assayed at either the ALS Mine laboratory or at Afrilab. All samples are analyzed for silver, copper, iron, lead, and zinc using Aqua regia and finished by AAS. Samples grading above 200 g/t Ag are reanalyzed by fire assay. Rigorous quality controls (QaQc) are applied at both locations.
