That's 350t being dumped from a height of 40m right there. In one scoop, a dragline can pickup your entire house including the garden to a depth of 5m.

A large, well-supported, safe, high-grade open stope mined conventionally with scraper winch & jack leg drills. No dilution & excellent ore recovery in 2026. Shows you dont need trackless machines to do a job well. NO AI could imagine something quite like this.

Some fun blasts to watch b/c its Friday. 🙂 The first two are almost perfect. Most of these blasts are very well drilled & controlled and only 2 that look a little over charged. Which one do you think they are? Some blasts (like the 1st) are contained with no free face to break to, these are called "box cuts" which charges set off in a V cut. Also, keep an eye out for blown out shots on each blast - a sign of good charging & stemming.

Shaft Sinking 101: A really excellent showpiece on shaft sinking activities on one of Oyu Tolgoi's new 9m diameter, circular shafts. 👇😃 Shaft sinking is a very exciting & hazardous mining activity. It also costs a lot of money. I will explain some of the seen activities in this🧵
