geophysics association, to compensate for this deficiency and supply the necessary raw materials , we have no other way than to focus on deep and subsurface discoveries . our rosini mines are the mines that they are showing up, these are ending day by day in the country, and we need them we have to explore below the surface if we can't do it at the same time. with the growth of the mining industry, we should develop exploration and not explore new deposits, well , we will surely face challenges in the future, of course, according to geological experts, it is necessary to explore deep in the earth , the best way is to use modern equipment and technologies. please help us to explore the geophysical methods under the dam. alhamdulillah, this knowledge exists in the country, maybe in the past years and this work it is mostly done by foreigners, now by iranian companies, alhamdulillah , it exists in our depths 40, 50, 60 meters successful we are trying to come up with geophysical methods and actually explore mines. now, although according to the head of the geological and mineral explorati
