Giant porphyry molybdenum deposits are best exemplified by the Climax and Henderson deposits in Colorado. The high grades of these deposits are probably inherited from magmatic molybdenum concentrations of about 4 to 5 ppm, which are high for metaluminous rhyolitic magmas that average about 2 ppm molybdenum.

The major ore deposits are of porphyry, porphyry–skarn, skarn, vein, and sedimentary types. Porphyry molybdenum deposits contain 77.5% of the Chinese Mo reserves, with lesser amounts in porphyry–skarns (13%), skarns (5.1%), and veins (4.4%). Exploitation of sedimentary-type molybdenum deposits thus far has been uneconomical.

Mining. Molybdenum occurs in nature in chemical combination with other elements. There are various molybdenum-bearing minerals, but the only one of commercial significance is molybdenite (MoS2) - a natural molybdenum sulfide. In ore bodies, molybdenite is generally present in quantities from 0.01-0.25%.

Molybdenum was discovered by Carl Wilhelm Scheele in 1778, and was isolated and named by Peter Jacob Hjelm in 1781. The most important ore source of molybdenum is the mineral molybdenite; a minor amount is recovered from the mineral wulfenite. Molybdenum commonly is recovered as a by-product or co-product from copper mining.
