The main activities of mine development include:

• collecting more technical, environmental and socio-economic data to increase the company's knowledge of the resources. This means more samples, more drill holes, and more field tests;
• developing the mine plan and infrastructure;
• consultations between government and mining companies to make sure that regulations are met. Mining companies also consult with communities to make sure that their needs and requirements are addressed;
• evaluating financial, socio-economic and environmental impacts; and
• obtaining permits and licenses.

The final evaluation of the project is carried out and the production decision is taken. The mine and its facilities are built, ready to start operations.
