Which features of a mineral deposit are studied during exploration?

During the exploration phase, geologists study a mineral deposit to determine its key characteristics and economic viability. The primary features examined include:

• Physical Dimensions and Geometry: Exploration aims to define the deposit's size, shape, and orientation in space, including its depth and location relative to the surface. This often involves identifying structural features such as joints, faults, and bedding planes.12
• Mineral Quality and Distribution: Geologists analyze the mineral content, including the grade (concentration of valuable minerals) and how that grade is distributed throughout the deposit.13
• Geological Context: Studies identify the surrounding rock types, specifically the hanging wall (rock above the ore) and the footwall (rock below the ore).3
• Rock Properties: The strength of the rock material is assessed to inform mining and safety decisions.2

To gather this data, professionals use techniques such as core sampling, trenching, and the construction of three-dimensional models to visualize the ore body at depth.32
