The only way that Botswana is going to have a long and continued proud history of diamond exploration and diamond mining is to spend money on diamond exploration, Botswana Diamonds MD James Campbell said on Tuesday, when he urged the country to adopt the Canadian flow-through incentive scheme to boost the funding of exploration risk. Campbell made this special plea for diamond exploration investment ahead of his prepared presentation in response to the comment of Econsult MD Keith Jefferis on day one of the conference that Botswana’s diamond mining industry had gone ex growth, and while the country’s diamond sector would not disappear, it would not grow either.
