Project Highlights
- Commenced commercial production in April, 2010
- An operating molybdenum mine in South Korea
- Every year, approximately 20% of world moly output is consumed between Korea and Japan
- Easy access to markets in China and Japan
- High-grade molybdenum deposit
- Close proximity of ore body to the surface
- Great resource expansion potential in and around current mining area
- No need for tailings dam: Saving significant expenditure
- Tailings from NMC Monald Mine are sent to nearby cement makers
- eliminating the need of tailings dam- eliminating the environmental liability
The NMC Moland Molybdenum Property is located 170 km southeast of Seoul, South Korea.
Molybdenum mineralization has been known to exist on the property since 1966.
The property covers 822 hectares and is held as 3 mining licenses with each lease or claim being 274 hectares. In addition, 6.2 hectares of land were purchased to act as a buffer between the property and surrounding agricultural land.
The property is a two hour drive from the metropolitan area of Seoul on major highways, a seven minute drive on completely paved roads from the exit off Choongang highway.
The NMC Moland Molybdenum Property contains a skarn zone hosted in Ordovician carbonate sediments. The skarn is over 800 m long and is adjacent to both Jurassic and Cretaceous felsic intrusions. Molybdenite occurs in fracture zones within the skarn and in disseminated form.
Exploration is carried out by systematic drilling of the skarn zone, following existing mineralization to depth. Wide step-out holes at 80-160 m intervals done in 1981-1982 act as a guide to following the extension of the body to the east and two existing adits expose the host rocks.
NMC drilled a total of 4,641 m in 61 holes during 2009, 2010 and 2011. Both AQ and BQ diameter holes were drilled from underground. In 2009, 12 holes were completed from the 217 m level. In 2010, NMC completed 17 holes from the 257 m level and 24 holes from the 217 m level. In 2011, 8 holes were completed from the 245 m level.
A new ramp 1,200 m long was constructed in 2008. Underground crushers and screens were installed in 2009, as well as a 1,000 TPD mill. Bench metallurgical tests have been completed.
The NMC Moland Molybdenum property contains Indicated resources of 1,669,000 tonnes grading 0.35% MoS2 and Inferred resources of 2,094,000 tonnes grading 0.32% MoS2 at a 0.14% MoS2 cut-off.
Processing Plant
A 1,000 TPD flotation plant has been constructed. The outer building and settling tanks and ore bin are completed and both of the ball mills, two spiral classifiers and 4 banks of flotation cells are installed. Two large filter presses are also installed to dewater the tailings with the water to be recycled with sediment removed. The tailings are shipped to a cement plant to be incorporated in cement or cement block production hence eliminating the need for a tailings dam.
Resource
Mineralization
The molybdenite mineralization is hosted in an 800m long skarn zone composed of clinopyroxene, crystalline limestone (marble), limestone (skarn) and dolomite. Widths of skarn with MoS2 are up to 80m wide and extend 500m to depth. Molybdenite occurs as "veins" in fractures within the skarn and can become intensely clustered where molybdenite is greater than 20% in confined areas of 1m-2m widths. Molybdenite occurs as disseminated flakes throughout the skarn and is common in "banded" skarn.
