Catoca revenue loss linked to Angola’s diamond marketing policy

23 march 2018

Sociedade Mineira da Catoca said Angola’s diamond marketing policy, which lacks transparency in the buying and selling of rough stones, has caused the company to lose about $450 million in revenue over the last six years, a local newspaper has reported.
A local news agency had attributed the loss to the country’s economic challenges.
Company deputy director-general, António Galiano was quoted by Folha 8 as saying that it was necessary to urgently improve the diamond sales policy in Angola.
Angola appointed a commission last December to revitalise the marketing policy for rough diamonds to ensure greater transparency in the process of buying and selling diamonds in the country.
Meanwhile, Galiano said the loss in revenue had affected the company’s exploration and discovery of new diamond fields.
He said the "preferred buyers" involved in the selling of rough diamonds should be closely monitored, since the majority of them do not contribute to the country’s economic development.
Catoca produces more than 80 percent of Angola’s total output in volume terms.
It was expected to produce 7 million carats this year from 7.4 million carats registered in 2017.
