Reduced ore loss, dilution and misclassification saves Red
Dog zinc mine US$6.5 million per year
Teck’s results show that Red Dog Operations saves an estimated US$6.5 million1 annually through blast movement monitoring.
The movement that occurs at Red Dog is demonstrated in this example blast. Movement variation of ±50% from the mean horizontal is common, and occurred in this blast.
- Measured horizontal movement ranged from 12.8 – 34.5 ft. (4 – 10.3 m) and vertical movement up to 17ft. (5 m)2
As a result of accounting for actual blast movement, and not relying on visual controls, Red Dog mine:
- Prevented 18,106 Tons of waste being sent to the mill (14% dilution)
- Avoided ore type misclassification of 16,888 Tons
- Recovered an additional 10,246 Tons of ore

“The information we get from the blast movement sensors allows us to track the movement of ore in greater detail than ever before, leading to improved productivity and sustainability at our operation.”

In this example blast, accounting for blast movement recovered 10,246 Tons of ore, and avoided 18,106 Tons of dilution.
