More Petra updates 


Petra’s five mining operations are all focused on ‘hard rock’ kimberlite pipe orebodies (as opposed to alluvial deposits). In Tanzania, Petra operates the open pit Williamson, mine where ore is drilled and blasted from the surface. In South Africa, the Company operates four underground mines, which use ‘cave’ mining to access one block of ore at a time, exploiting gravity and the kimberlite’s inherent weakness to enable the ore to collapse autonomously. By opening up access to new blocks of ore at its underground mines, Petra will be able to mine pure kimberlite ore, undiluted by waste rock, thereby substantially increasing the grade. Petra also operates extensive tailings operations in South Africa, whereby material that has already been through the plant can be reprocessed to extract further diamond content.

Exploration and Development:

Petra is exploring for new economic diamond deposits in a highly focused programme in Botswana and South Africa (where it took on a new prospecting right in 2015). It is also re-evaluating its existing kimberlites with respect to size, grade and diamond bearing potential.

Diamond Sales and Marketing

At the end of each production cycle, the diamonds produced at Petra’s mines are delivered to its sorting facility, where they are cleaned and acidized, before being sorted into international sales assortments. High quality larger stones or coloured stones are sold as single lots. Individual mine production is kept separate, providing buyers with an additional level of knowledge about the goods they are purchasing based upon each mine’s unique diamond characteristics. Petra will hold 7 tenders in 2016, each of which lasts 4-6 working days, during which participants view the assortments and place a confidential electronic bid on the parcel of their choice. At the end of the tender, the highest bidder wins the parcel.
