   Iljaq potash deposit
  
   Abstract
   At 1998, exploitation from a small salt mine in the northwest of Iran (Iljaq salt mine) was led to exploration of transparent and large crystals of picromerite. Therefore prospection for potash minerals in the Miocene evaporate rocks of the NW Iran and semi-detailed exploration of potash in the Iljaq salt mine and Pol salt dome (Zagros) started.
   The exploration of potash in the Iljaq was started by 1:1000 topography and geology mapping. Then the geophysical survey was conducted by magnetometry and gravimetry methods. The network grid was 20 by 50 m. radiometric studies by the Atomic Energy Organization showed higher potentials in the western limb of dome. These studied led to identification of suitable points for drilling.
   At 2000, drilling project was started. At the first period of drilling, 1764.7 m drilling was done in 11 holes finished at winter 2002. The second period of drilling completed with 1605.4 m drilling.
   This report contains the result of studying cores, well-logging and preparation of geological cross sections, well correlation, structural geology, reserve estimation and evaluation, followed by ore-dressing and feasibility studies.
   The report recommended open-pit mining for the first block of the mine. Supplying the required water is the main challenge of the Iljaq potash deposit.
