Mine sites can be complex ventures to build, operate, and close. To help better understand their complexity, its a good idea to look at some site layouts. Each mine site is unique in concept and presents its own operating challenges.
The following are some satellite images for a few mining operations. It’s interesting to see the layout decisions that engineers had to make when designing each project.
New satellite images are periodically posted on this website and on X (@KJKLtd ).
Canada's highest grade diamond mine, mining three kimberlite pipes.
Owned by Barrick / Newmont, this expanded 38,000 tpd operation has an expected life to 2040 and beyond.
The deposit's location is within the Angara River, with a large dike to divert the river. This mine is in a flowing river.
The K1/K2 mines saw sudden water inflow in 1986. In 2021 the two interconnected mines were allowed to flood. The new K3 mine is supplying potash ore to the existing plants via overland conveyors.
Owned by BHP, this mine used a bucketwheel excavator and dragline to strip 40 m of saturated sand and soft clay to expose 6 m of high grade bauxite ore.
Owned by Newmont, this is located in an active volcanic caldera and rock temperatures can exceed 100°C.
The Barnat pit will operate from 2019 until 2029, while the Malartic pit operated from 2011 to 2023. The town of Malartic is right on the edge of the pit.
Owned 75% by Newmont, approx 3.5 million oz in reserves still to be mined. Illegal mining of creeks and rivers all around the region.
The Mount Polley tailings pond experienced a tailings spill in August 2014. The 4 sq km pond spilled an estimated 25 million cubic m of material into Quesnel Lake.
Owned by New Gold, this is Canada’s only block cave mine in operation. Reserves are 39 Mt at 0.72% Cu, 0.65 g/t Au.
Each mine produces between 150,000 and 350,000 barrels of bitumen per day.
Owned by New Gold, the open pit mine is now transitioning to underground only. Mining is expected to end in 2031, giving a 14 year life, that might be extended.
