Platinum Group Metals (PGMs): Exploration and Evaluation Techniques

The evaluation of Platinum Group Metals (PGMs) deposits in igneous rocks is critical for mining projects. This article explores the advanced methods and tools used in locating and assessing these valuable resources.

Geological and Geophysical Surveys

PGMs are often associated with ultramafic and mafic rocks. Geological mapping combined with geophysical techniques aids in pinpointing potential deposits.

• Magnetotellurics (MT): Assesses electrical conductivity to locate mineralized zones.

• Gravity Surveys: Detects rock density variations linked to PGM deposits.

Drilling Operations

Drilling is essential for accessing and evaluating PGM deposits. Different rigs cater to specific exploration needs:

• Rock Core Drilling Machine: Provides high-integrity core samples for detailed study.

• Portable Full-Hydraulic Core Drilling Rig: Ideal for challenging terrains with efficient core recovery.

• Exploration Survey Rig: Optimized for multi-directional drilling in complex geological settings.

Metallurgical Testing

Samples undergo rigorous testing to determine the recoverability of PGMs like platinum, palladium, and rhodium.

• Assay Techniques: Include fire assay and inductively coupled plasma mass spectrometry (ICP-MS) for precise measurement.

• Mineralogical Analysis: Identifies the mode of occurrence and association of PGMs within the ore.

Economic and Environmental Considerations

Feasibility studies factor in extraction costs, environmental impact, and market trends to ensure sustainable mining practices.
