nature of the composition of the drainage and fresh water are not well understood at this<br />
stage of the project and the technology required for water treatment will need to be defined<br />
during the next stage of engineering studies. The plant sewerage will drain to a septic tank.<br />
17.1.10 Auxiliary Services Area<br />
17.1.10.1 Compressed Air<br />
High pressure air will be provided in the plant by the concentrates pressure filter compressor<br />
which provides air to operate the lead and zinc concentrates pressure filters. High pressure<br />
plant air will also be used for instrumentation in the plant. High pressure air will also be used<br />
for instrumentation air in the plant after it has passed through a dryer<br />
17.1.10.2 Diesel<br />
Diesel fuel will be required for underground and surface mobile equipment and onsite<br />
emergency power generation equipment. A fuel storage container will be located at the plant<br />
site and a fuel rail tanker will be used to distribute fuel underground. The emergency<br />
generator will have a dedicated diesel storage tank.<br />
17.1.10.3 Emergency Generator<br />
During power outage, one diesel generator (75 kW) will supply energy for the paste<br />
thickener rake and pumps at the solid liquid separation area and lighting. The critical loads<br />
are the thickener rake motor, the thickener underflow pump and general lighting.<br />
17.1.10.4 Tailings Disposal Facility (TSF) Area<br />
Paste thickener underflow is directed to the paste tailings storage (1400-TSF-001) facility by<br />
gravity or by pumping. The TSF deposit is provided with a water drainage system that allows<br />
for water recover. The reclaimed water, which includes the water from the TSF surface, will<br />
be pumped to the Paste Thickener to remove any suspended solids (if any) in the water and<br />
the Paste Thickener overflow then reports the carbon columns and onto the process water<br />
tank.<br />
17.1.10.5 Plant Spillage Containment Area<br />
All excessive plant spillage from the crushing, milling and flotation sections will drain to the<br />
plant spillage containment dam. The dam has a sloped base, is lined with a geomembrane<br />
and equipped with a vertical spindle pump suspended from a frame and the pump is lowered<br />
into the slurry with a chain block. Any spillage in the dam will be hosed to the pump and<br />
pumped to the mill discharge sump.<br />
17.1.11 Site Layout Considerations<br />
The project site is steep, high-altitude terrain that has limited flat space. Due to these<br />
considerations, particular attention is required to develop acceptable sites for the facility. The<br />
general site arrangement is show in Figure 17.2 and the plant layout is presented in Figure<br />
