Aim-listed Botswana Diamonds has started an active programme of exploration in Orapa and Gope, in Botswana. The exploration programme was being led by a team from Botswana Diamonds’ joint venture partner Alrosa. “The exploration programme on two licences in the Orapa area of Botswana has great potential. The new licence PL 260 already has known kimberlites containing diamonds. We want to test the belief that the grade improves at depth so we are taking a bulk sample to get reliable results,” Botswana Diamonds chairperson John Teeling said in a statement on Wednesday.
