4.0 BUILDINGS AND STRUCTURES
4.1
SECURITY OFFICE, FIREFIGHTING, AND FIRST AID
The security office, firefighting and first aid building will be a pre-engineered structure complete
with insulted steel roof deck and steel wall cladding. The building will be divided in two sections.
The first section will be used as a security office and will have a safety training room. The
second section will be used as the firefighting and ambulance base, and will include a first aid
center.
4.2
MAIN HYDROMET BUILDING
The main Hydromet building will be divided into areas for administration, shower and change
room, analytical laboratory, light vehicle maintenance, workshop and storage, and the Hydromet
process area. Concrete masonry block walls will be built between each area.
The administration area will host the offices for administrative and technical personnel, as well
as the lunch room for employees.
The shower and change room area will include lockers, change rooms, and shower areas. The
laboratory area will host the equipment required to analyze process samples as well as
environmental samples. A sample storage area is also provided.
The light vehicle maintenance, workshop, and storage area will include a truck shop to perform
maintenance on vehicles, a workshop to perform maintenance on the various process
equipment and instruments of the facility, and a spare parts storage area.
The main Hydromet building will host the process unit operations, the mechanical and electrical
room, and the control room. The interior of the Hydromet building will be built using multi-levels
of steel platforms for ongoing operation and maintenance needs. The plant grading is designed
to isolate each area within its concrete containment. Major equipment will be installed on
independent steel platforms. The platforms will be completed using grating, handrails and kick
plates as required by Mine Safety and Health Administration regulations.
In addition to the buildings, an outdoor laydown area will be built to receive and store large
pieces of equipment and bulk supplies. The Hydromet facility is designed such that every
building and equipment is contained, and any run-off material will be collected in a sump, and
disposed of properly.
4.3
PRE-CONCENTRATE HANDLING
The pre-concentrate handling system is composed of an access road, an unloading station, two
storage silos, and one feed conveyor. The pre-concentrate trucks will use their own gate to
reach the pre-concentrate unloading station, located on the southeast corner of the Hydromet
Plant. The trucks will discharge their load in an enclosed building to an underground hopper. A
conveyor will transport the pre-concentrate from the discharge hopper to the storage silos. The
Hydromet Plant feed will be provided by one conveyor fed from the storage silos.
