In 2000, a small geological survey team from De Beers Ltd, the largest diamond mining company in the world and a global top 500 enterprise, moved into a camp on the banks of the Save river. They secured an Exclusive Prospecting Order (EPO) over a large area and began to probe for raw diamonds. They found ample evidence of diamonds and sent loads of soil to Johannesburg, South Africa, for analysis but after six years decided that the qualities of the stones on site were not good enough to warrant commercial exploitation.

In London another company, African Consolidated Resources (ACR), formed by a group of Zimbabweans, watched the developments very carefully. When De Beers failed to renew their EPO over the area, they moved very quickly to take up the EPO and registered claims over 3 800 hectares of land that they identified as having the most potential.
Under the guidance of an experienced Australian geologist, the company cut deep trenches across the site and in a matter of weeks discovered gem quality stones. Although less than 20% of all the stones recovered were in this category, they felt that it was commercially viable because of the low cost of extraction.
