While on topic, is anyone familiar with any late-age attempts on commercial gold mining in Indus river sands in Baltistan? Historically this region (recorded as 'Dadi' or 'Dradi' in ancient scriptures) had significant gold mining activity until a few centuries ago. Even today some people, though poor, make their living by manually sluicing gold from sands in this area.
I think this area may have some potential of heavy minerals and/or gold if explored by hyperspectral imaging and mined by scientific methods. Following is abstract of a geological survey carried out in late 50s, perhaps by some German entity.
"Title: URANINITE OCCURRENCE IN HEAVY MINERAL SANDS OF THE INDUS VALLEY
In the gold-rich sands of the Indus River, especially in the northern part of West Pakistan, uraninite, monazite, scheelite, zircon, ilmenite, and previously unknown minerals were discovered. Uraninite exhibits an abnormally high radioactivity which could be traced back to the decay products of the radium series. The type of radiation was investigatod and discussed. Chemical and physical separations were made to detect the raniation source. Uraninite is especially enriched in the smallest grains, generally in idiomorphic form. The occurrence was compared with other known occurrences. It was shown that a weathering of uraninite can follow different patterns and that a liquid transport of several 50 km as well as an enrichment in alluvial ores results. The economic possibilities were mentioned." |
