Tungsten Ore Evaluation: Cutting-Edge Techniques in Igneous Rock Exploration

Tungsten, known for its durability and high melting point, is a critical mineral for industrial applications. Evaluating tungsten deposits in igneous rocks involves advanced exploration techniques and modern equipment.

Preliminary Surveys

The evaluation process begins with a thorough understanding of the geological environment where tungsten minerals like scheelite and wolframite are found.

• Geochemical Surveys: Analyze soil and stream sediments for tungsten anomalies.

• Geophysical Methods: Magnetic and radiometric surveys identify favorable structures and mineralized zones.

Exploration Drilling

Drilling provides critical subsurface data to evaluate tungsten deposits accurately. Key drilling tools include:

• Exploration Coring Drill Rig: Captures undisturbed core samples, essential for structural and mineral analysis.

• Portable Full-Hydraulic Core Drilling Rig: Highly mobile and efficient, suitable for diverse terrains.

• Exploration Survey Rig: Combines precision and speed for deep and targeted drilling operations.

Sample Analysis

Analyzing core samples is crucial for assessing ore quality and economic feasibility:

• X-ray Fluorescence (XRF): Determines tungsten concentration and associated elements.

• Petrographic Analysis: Studies mineral composition and texture for resource evaluation.

Economic Feasibility and Resource Estimation

The final step involves evaluating the economic viability of mining the tungsten deposit. Resource estimation models consider grade, ore volume, and market demand.
