What about this project?
The basic concept of the business model is the creation of a cryptocurrency wich will be backed up by real gold. Each token will not have a "price tag," but a "weight" that will be directly tied to the volume of gold mined. Gold mining enterprise will be established in Northern Sudan with the support of the local government.
As a result of geological exploration of the area experts from India found that the minimum degree of average mineralization of gold is about 7.5 g per ton of ore. It was also estimated that a fully functioning plant would be able to process up to 1500 tons of ore per day and produce approximately 10kg of gold per day.
