Between March 2010 and March 2012, about 1.6 trillion rials ($130 million) was invested in the field of mineral exploration, he added.
Earlier this month, Jafari said that Iran plans to extract some 400 million tons of minerals by the end of the current Iranian calendar year (March 20, 2013).
The figure will be around 15 percent higher year on year, he added.
Iran's mineral extraction is projected to hit 570 million tons by the end of the fifth five-year development plan (2015).
On December 17, Jafari said that some 1.6 trillion rials (about $130 million) has been invested in mining explorations in Iran during the past three years.
Iran is ranked among the 15 major mineral-rich countries of the world and exports its industrial and mineral products to 159 countries, including Iraq, China, the United Arab Emirates, India and Afghanistan.
