Water
In Mexico, water rights are managed by the Comisión National del Aqua (“CNA”). According to Mexican water rights legislation, all users, whether individuals or companies, must pay for the right to use national waters regardless of how the rights were obtained, with the rates being determined by the availability of water and the method of extraction.
The project’s main water consumer will be the heap leach facility. The Feasibility Study envisioned using an estimated average annual consumption of 45.6 litres/second (723 US gallons/minute) due to evaporation and water retained within the heap as a result of heap irrigation. In addition to make-up water used for the heap leach facility, the Feasibility Study called for the open-pit will consume water for dust control with the camp consuming water for domestic purposes. Average annual consumption for all purposes was estimated at 58.8 litres/second (932 US gallons/minute), with maximum estimated consumption being in the month of June at 100.2 litres/second (1,588 US gallons/minute).
The project’s source of water was to be the Rio Mulatos with water withdrawn east of the proposed open-pit and pumped to a water storage reservoir on the Arroyo Mulatos, above the proposed open pit. A dam was to have been built across the Arroyo Mulatos to create this reservoir, which needs to have a storage capacity of about three months to ensure water supply during the driest months of the year when the Rio Mulatos would
not be able to supply sufficient water for the project as proposed by the Feasibility Study. The rights to the water have not as yet been established. Discussions are continuing with the Mayor of Sahuaripa to rent or lease the town’s unused water supply.

Current work of the planned heap leach test is designed as the first step in evaluating the feasibility of operating initially at a smaller scale than planned by the Feasibility Study. The purpose is to test the higher grade core of the deposit and evaluate if a profitable mining operation can be started in the core. Prior to the results of the heap leach test and the probable need for more testing it is not possible to say what the water needs of a smaller scale mining operation may be or if such an operation is profitable.

Regulations require that an environmental impact statement, known in Mexico as a Manifesto Impacto Ambiental (“MIA”) be prepared by a third-party contractor for submittal to SEMARNAP. Studies required to support the MIA include a detailed analysis of the following areas: soil, water, vegetation, wildlife, cultural resources and socio-economic impacts. Although the regulatory process in Mexico does not have a public review component, proof of local community support for a project is required to gain final MIA approval. A risk analysis must also be prepared in conjunction with the MIA for approval by SEMARNAP.
A number of other approvals, licenses and permits are required for various aspects of a mine development. The most significant permits for the development of the Salamandra Project, other than MIA approval, are permits to extract water from the Rio Mulatos and a blasting permit, issued by the Mexican Army, to
purchase, store and use explosives.
MSA received approval for its MIA in July 1997 for the development of an open-pit mining operating extracting 30,000 tonnes per day and for a crushed ore heap leaching facility producing 15,000 tonnes per day. The permit application proposed moving the village of Mulatos. Separate environmental studies and
subsequent approvals have also been received for the construction of a new 130 km, 115 kV transmission line from the El Novillo power station, the construction of a new access road from the town of Yecora, and the relocation of the village of Mulatos. The MIA resolution is valid for a period of 10 years from the date of issue.
