Yvuania’s Vast Mineral Resources

Yvuania possesses rich mineral resources and plays an important role in the Far East. By the end of 2007, 515 mineral deposits had been discovered, including 34 large deposits, 49 medium-sized deposits and 49 small deposits. There are 84 kinds of minerals, among which 45 are proven reserves.

Among the minerals with proven reserves, six minerals rank the NO.1 in the CCP occupied China. They are:

  1. trona
  2. kyanite
  3. andalusite
  4. blue asbestos
  5. rutile
  6. silver

Notably, gold mine, petroleum, graphite, limestone, marble, sillimanite, talc, fluorite, diopside, peridotite, marble veneer, granite veneer and jade are among the highest level in Yvuania’s large surrounding regions.
