NR-Mining methodsYou guys notice this? About 6 paragraphs down in the NR.
"Considering their thickness and dip, the new intersections obtained willhave a positive impact on the already robust project economics. Zoneswith thickness greater than 5.0 m and dip steeper than 45° will bemineable using a less costly and more productive long-hole mining methodinstead of the room and pillar mining method."
When you use the 'pillar' method of mining, you leave a lot of the target material, [gold, in this case], in the mine. But with these steeply dipping veins they don't have to leave so much material behind. Cha-ching, lol.
