Summary:
Kidd Mine is a VMS Cu-Zn-Ag deposit. Mineralisation occurs within a rhyolitic volcanic/volcaniclastic sequence as massive sulphide lenses of dominantly pyrite-pyrrhotite-sphalerite-galena-rich ores that are underlain by copper in chalcopyrite stringer zones.
Mining Methods
- Sub-level open stoping (SLOS)
- Paste backfill
Summary:
Kidd Mine located in Timmins, Ontario is the deepest base metal mining operation in the world with active mining taking place at 9,600 feet and the shaft bottom is currently at 9,889 feet, more than three kilometres deep.
The current extraction method at Kidd Creek is sublevel open stoping.
Lafarge has operated the paste plant since 2004. Over time the operational capacity has expanded resulting in increased reliability, decreased cost per tonne, and greater throughput. Lafarge’s backfill support services including processing and delivery of sand and tailings resulted in significant cost savings for the mine. Lafarge also provided a custom designed paste - TerraFlow ™ 90.
Extracting ore at 3km below the earth's surface requires the development and application of innovative processes, methods and technologies that are unique in the global mining sector:
- Cold stope system decreases temperatures at lower levels, and reduces electricity consumption and greenhouse gas emissions;
- Automated scoop trams increases safety and productivity;
- Some of the world's largest vent fans provide ventilation-on-demand;
- One of the largest fibre optic infrastructures in Northern Ontario used to communicate and remotely operate equipment 3km underground.
