Although small intervals of rich molybdenum (Mo) mineralization have been discovered the ore deposit scale is limited and the condition of deep ore is still unknown. To explore these deeper targets a modified large-loop TEM system was used in the Sharang area.

    Molybdenum. Molybdenum (element #42 symbol Mo) is a metallic lead-gray element with a high melting point (4 730 degrees Fahrenheit). This is 2 000 degrees higher than the melting point of steel and 1 000 degrees higher than the melting temperature of most rocks. Molybdenum was discovered by Carl Wilhelm Scheele in 1778 and was isolated and
