gold dredge in California stopped operating in October 1968. Gold dredging in the adjacent States had already ceased because of increasing operating costs, decreasing placer values, and the fixed price of gold.3 Two gold dredges and one platinum dredge were still operating in Alaska in September 1969.
The Assosa gold deposit is just one of the many yet untapped sources of gold that could easily put Ethiopia in the top 5 gold producing countries in the world.

The tailings are continuing to express pore water as they continue to consolidate. The pore water and underdrain water is comingled with all site waters, treated at the treatment plant, and discharged through outfalls 002 and 003.
Gold abundance in the Earth's crust is 0.002 per 106 atoms of silicon [2]. Gold average economic abundance in the ore today is in the range of 0.1 to 0.2 oz/ton or 3.42-6.84 ppm, but deposits yielding grades to the fire assay which are as low as a tenth of those values are also exploited [2].
