It's a comprehensive analysis conducted to assess the economic, technical, and environmental viability of a mining project. It serves as a decision-making tool for investors, companies, and other stakeholders.

Drilling is a crucial part of the exploration phase of mining, as it provides detailed information about the subsurface, which is vital for mineral resource estimation, mine planning, and the overall feasibility of a mining project.

It's the process of mapping the physical features of a specific area, including natural elements like hills, valleys, bodies of water, and human-made structures such as roads, buildings, and infrastructure. 

Geological surveys involve the study of rock formations, mineral deposits, faults, folds, and other geological structures. Geological mapping, which involves the creation of detailed maps showing the distribution of rocks and minerals, is an essential part of this process.

Several geophysical methods are used depending on the characteristics of the area being surveyed, the type of mineral being sought, and the depth of exploration.

Exploration and development are essential stages in the lifecycle of a mining project. These processes involve the systematic search for mineral resources, evaluation of their potential, and the subsequent planning.
