Balkhab (Persian: بلخاب) is a district of Sar-e Pol Province, Afghanistan.

It is valued at billions of U.S. dollars and one of the biggest untapped copper mines in Afghanistan.

The discovery appears to be a volcano genetic massive sulfide deposit—a deposit type which could supply much of the world's gold, copper, lead and zinc.

On October 5, 2018, in Washington, D.C., Afghan officials signed a 30-year contract for a copper mining project involving a $56 million investment by investment group Centar and its operating company, Afghan Gold and Minerals Co., for exploration of an area covering 500 square km, with development of mining due to begin thereafter.
