Project Description
Ambatovy Project
5
January 2006
Approximately 40 ha is required for a pump station on the eastern bank of the
Mangoro River. The planned site is situated on State land. A long term lease will
be based on the Mine Site contract terms.
The water pipeline (about 23 km) traverses 8 privately owned plots and 7 state
owned plots. A Right of Way will be negotiated with the respective owners.
Compensation will be negotiated in the event of damage or destruction of
property.

INFRASTRUCTURE
Figure 2-1 presents the general layout of the mine infrastructure. Water supply to
the mine for ore processing will be from the Mangoro River, about 20 km west of
the site. The maximum design flow will be 1,000 m
3
/hr although the nominal
required rate will be much less. The expectation is that a significant quantity of
the water required will be supplied by surface water collection ponds in the mine
area. Power requirements for the mining and ore processing facility will be
supplied by diesel-generated power plants located at the mine site.
Figure 2-2 presents the general layout of the river intake facility. Figures 2-3 and
2-4 present the general arrangement of the runoff collection ponds and the
conceptual water balance.
A fresh water pipeline corridor will be established from the river intake facility to
the mine area. The pipeline will be 600 mm in diameter, 23 km long and will be
buried.
The existing road infrastructure in the region consists of Route Nationale (RN) 2
(asphalt and paved) and RN44 (first 20 km recently asphalted) highways. An
access road from RN44 to the mine site was established earlier, and this road will
be further upgraded. The majority of the supplies transported to the mine site
will be through the road system. The existing railway line from Toamasina to
Moramanga and through to Antananarivo will also be considered for material
transport.
