Copper is a vital mineral used extensively across industries. Evaluating copper deposits in igneous formations demands a combination of traditional methods and advanced technology to ensure precision and cost-efficiency.
Prospecting for copper deposits starts with regional surveys. Understanding geological indicators like alteration zones and sulfide mineralization is key.
Remote Sensing and Aerial Surveys: High-resolution imagery helps identify promising areas.
Field Sampling: Rock and soil samples are collected for geochemical analysis, narrowing down target zones.
Drilling is indispensable for assessing ore bodies. The following rigs are widely used for copper exploration:
Exploration Coring Drill Rig: Captures high-quality cores for mineralogical studies.
Portable Full-Hydraulic Core Drilling Rig: Offers flexibility in rugged terrains.
Exploration Survey Rig: Designed for high-precision sampling in deep ore bodies.
Drilling data provides insights into ore grades, thickness, and spatial distribution, critical for resource estimation.
Core samples undergo detailed analysis to determine the presence of copper minerals like chalcopyrite, bornite, and malachite. Analytical techniques include:
Optical Mineralogy: Examining thin sections under a microscope for mineral identification.
X-Ray Diffraction (XRD): Identifies crystalline phases and mineral associations.
Modern geophysical tools complement drilling and sampling by providing subsurface imaging:
Induced Polarization (IP) Surveys: Detect disseminated sulfide minerals.
Magnetic Surveys: Identify anomalies linked to ore-bearing formations.
Economic evaluation follows, considering ore processing, transportation logistics, and environmental regulations. Comprehensive feasibility studies ensure sustainable and profitable operations.
