Colony Construction is a trusted mining construction company in Canada, delivering steel process facilities, mill buildings, camps, and heavy industrial structures for mines across British Columbia, the Yukon, Nunavut, Northwest Territories, and internationally. With four decades of experience in remote, cold-weather, and high-altitude environments, we fabricate, deliver, and erect the steel that keeps mines producing.
Mining Construction Expertise
Since 1985, Colony Construction has completed more than 700 projects, and mining has been at the core of our portfolio from the start. Our steel has gone up at gold, copper, silver, diamond, and polymetallic operations – from the BC Interior to the Yukon, from Alberta’s oil sands to Peru’s Andes and Russia’s Far East. We understand that mining projects live or die on schedule, and that every day of delay on a process plant, mill, or crusher building pushes first-pour or first-production further out.
We have supplied mill buildings, truck shops, warehouses, conveyor galleries, crusher houses, thickener tanks, and camp accommodations for some of the most demanding mines in North and South America. Our work spans Pretium Resources’ Brucejack Gold Mine in northwest BC, the Diavik Diamond Mines in the Northwest Territories, Newmont’s Red Chris copper-gold mine, Teck’s Highland Valley Copper operations, Antamina in Peru, and the Kupol gold project in Russia’s Chukotka region.
Our engineering, detailing, fabrication, and erection teams coordinate directly with mine owners, EPCMs, and general contractors. We routinely work to mining-industry standards including CSA S16, CSA W59, CISC Code of Standard Practice, and site-specific seismic and wind criteria. Whether the project is a greenfield build or a mantle rebuild inside an operating facility, Colony brings the capacity, the people, and the logistics network to deliver.
Our Services for Mining
- Pre-Engineered Steel Buildings – Fast-track truck shops, warehouses, core shacks, and equipment storage designed for heavy snow and seismic loads at remote mine sites.
- Conventional Steel Construction – Heavy structural steel for mill buildings, crusher houses, SAG and ball mill supports, conveyor galleries, and headframes.
- Hybrid Steel Solutions – Combined pre-engineered and conventional steel where portions of a mill need heavy crane-rated framing while offices and warehouses stay PEMB-efficient.
- Engineering and Detailing – In-house connection design and 3D detailing that reduces field rework and shortens erection time in short northern build seasons.
- Structural Components – Bridge crane runways, mezzanines, platforms, chutework supports, and equipment pedestals fabricated to tight mill tolerances.
- Design-Build – Single-source delivery that compresses schedule by overlapping design, fabrication, and erection on fast-track mining programs.
Challenges We Solve for Mining Clients
Remote Site Access
Many Canadian mines are accessible only by ice road, barge, or fly-in. Colony plans fabrication, packaging, and shipping around narrow delivery windows, pre-assembling sub-modules where possible so that field labour is minimized and critical steel lands on site before the window closes.
Extreme Weather and Arctic Conditions
Our steel is detailed and specified for temperatures that routinely reach -40 C, with appropriate CVN notch toughness, cold-weather welding procedures, and connection details that accommodate thermal movement. Erection crews are experienced in heated enclosures, glycol preheat, and winter work practices required on northern mining sites.
Environmental Compliance
Mining sites operate under strict provincial, territorial, and federal environmental permits. Colony integrates spill containment, secondary containment framing, and compliant cladding systems into the structure, and our project management tracks documentation required by owners and regulators.
Tight Production Schedules
On operating mines, a shutdown may last two to six weeks – and everything must be ready. We pre-fabricate, pre-paint, and pre-assemble as much as possible in our shops so that site work during a turnaround is measured in hours, not weeks. Our Teck HVC mantle rebuild work is built around this discipline.
Heavy Haul Logistics
Mill buildings and crusher structures involve over-dimensional and overweight loads. Colony coordinates pilot cars, permits, bridge crossings, and routing through our logistics partners, sequencing deliveries so erection crews have the right piece at the right time.
Seismic and Wind Design
Mines in BC’s seismic zones and the high-wind coastal territories demand rigorous lateral system design. Our engineering and detailing team works in SDS/2 and Tekla, producing connection designs that satisfy the governing site-specific hazard while still being economical to fabricate.
Mining Projects
Brucejack Gold Mine
Colony fabricated and erected steel for Pretium Resources’ Brucejack Gold Mine in northwest BC, a high-grade underground gold operation in rugged alpine terrain. The project required cold-weather erection and helicopter-supported logistics for remote components.
Diavik Diamond Mines
At Diavik, in the Northwest Territories, Colony supplied structural steel for facilities serving one of Canada’s most remote diamond operations. Steel was delivered over the Tibbitt-to-Contwoyto winter road, requiring careful sequencing with the narrow ice-road season.
Antamina Copper Mine
Colony fabricated and shipped steel to Antamina in the Peruvian Andes, one of the largest copper-zinc mines in the world. The project showcased our ability to work across international jurisdictions, coordinating export documentation, ocean freight, and high-altitude erection.
Kupol Gold Mine
For the Kupol gold project in Russia’s Chukotka region, Colony delivered structural steel to one of the coldest, most remote operating mines on the planet. The work required Arctic-grade steel specifications and winter-road logistics to remote barging ports.
Newmont Red Chris Mine
Colony supported the Red Chris copper-gold mine in northwest BC with structural steel for process and support facilities. The site’s remote location and seismic environment demanded disciplined detailing and cold-weather erection planning.
Teck HVC Mantle Rebuild Facility
At Teck’s Highland Valley Copper, Colony fabricated a mantle rebuild facility engineered around the massive crusher components serviced inside. The work required close coordination with mine operations to minimize impact on production.
Where We Build for Mining
Colony’s fabrication shops ship mining steel across Canada and internationally. We have active project experience in every major Canadian mining jurisdiction and maintain the logistics relationships required to move steel into the Arctic, across ocean freight, and into international mining districts.
Frequently Asked Questions – Mining Construction
What types of mining buildings does Colony Construction build?
Colony fabricates and erects mill buildings, crusher houses, conveyor galleries, truck shops, warehouses, core shacks, headframes, SAG and ball mill pedestals, mantle rebuild facilities, and remote camps. We work at gold, copper, silver, diamond, and polymetallic operations across Canada and internationally.
Can Colony deliver structural steel to remote northern mine sites?
Yes. We routinely ship steel over ice roads, by barge, and by long-haul truck to Yukon, NWT, and Nunavut mines. Our logistics team sequences fabrication around seasonal delivery windows and pre-assembles components where possible to reduce field work.
How does Colony handle cold-weather steel specifications?
Mining steel for northern Canada is specified with appropriate Charpy V-notch toughness and cold-weather welding procedures. Our detailing and QC teams confirm material traceability and weld procedure qualifications so the structure performs at -40 C and below.
Does Colony work on brownfield expansions inside operating mines?
Absolutely. Many of our mining projects involve expansions, rebuilds, or equipment replacements inside operating facilities. We coordinate closely with mine operations to plan work around shutdowns, minimize production impact, and meet tight turnaround schedules.
Can Colony provide design-build for mining projects?
Yes. Our design-build service is frequently used on mining projects where schedule compression matters. We overlap engineering, detailing, fabrication, and erection under a single contract, and our in-house engineering coordinates directly with owner and EPCM teams.
Has Colony built steel for international mines?
Yes. We have delivered structural steel to Antamina in Peru and Kupol in Russia, among other international mining projects. We manage export documentation, ocean freight, and in-country coordination through established partners.
What codes and standards does Colony design to for mining projects?
We work to CSA S16 for structural steel, CSA W59 for welding, and the CISC Code of Standard Practice, plus site-specific seismic, wind, and snow loads from the National Building Code and provincial amendments. International projects are delivered to the governing jurisdiction’s codes.
How quickly can Colony mobilize for a mining project?
Lead times depend on scope, but Colony’s in-house engineering and multi-shop fabrication footprint allow us to compress schedules significantly when required. For urgent shutdown work we have mobilized erection crews within days of award.
