March 30, 2015, Vancouver, BC - Rockwell Diamonds Inc. ("Rockwell" or the "Company") (TSX: RDI; JSE: RDI) announced today that it has reached an agreement to sell its non-core Tirisano Project ("Tirisano") in the North West Province of South Africa for a cash consideration of $6.3 million[1]. The Company is also pleased to provide an exploration update for the Middle Orange River ("MOR") region.

Disposal of Tirisano Project

Tirisano, located in the North West province some 500 kilometres from the Company's Middle Orange River operations, was identified some time ago as a non-core asset and a sale process was initiated. Tirisano was placed on care and maintenance in December 2012 and subsequently royalty contract miners were brought in to continue mining operations on the property. During the subsequent period the contract mining operations processed an average of 160,000m3 per month producing between 1,500 and 2,000 carats per month. Rockwell's 12.5% royalty on the sale of the diamonds was applied to the care and maintenance costs of the property and a portion of the overheads.

After evaluating a number of proposals as part of the sale process, the Company reached an agreement with a consortium made up of the royalty miners ("the Consortium"), who have operated at Tirisano for the past two years. The Consortium will acquire the entire issued share capital, together with claims on loan account in Rockwell's 100% owned subsidiary, Etruscan Diamonds Pty (Ltd) including the Tirisano mining right and its associated infrastructure, for a cash consideration of $6.3 million (ZAR 60 million) ("the Transaction"). The Consortium will therefore assume debt owed by Etruscan amounting to $3.5 million (R34 million) and the related environmental liabilities. The cash consideration will be settled by way of two initial payments totaling $2.1 million (ZAR 20 million), one in March and the second in April 2015, followed by 20 equal monthly instalments of $0.21 million (ZAR 2 million). The proceeds will be used to fund Rockwell's general working capital and investments related to acquisitions, additional exploration and ongoing development of the portfolio of mining and mineral rights.

The Transaction is subject to conditions precedent, including customary regulatory approvals.

MOR exploration update

As reported on March 9, 2015, Rockwell is expanding its exploration activities in the MOR, initially focusing on the Lanyonvale and contiguous Wouterspan properties. Both are considered to have significant potential to add to the Company's resources.

• At Lanyonvale, initial work will focus on the evaluation of the Rooikoppie Exploration Targets with potential resources of 3 to 4 million m3 of gravel, followed by fluvial alluvial Exploration Targets with potential for 1 to 2 million m3 of gravel. Completion is targeted for the end of October 2015.
• At Wouterspan, further pitting of the Rooikoppie gravels at a tighter grid spacing is planned with the intention of converting the initial estimates to Indicated Resources by February 2016.

Commenting on the Tirisano disposal and exploration update James Campbell, CEO and President said:

"The sale of Tirisano, which has been identified as non-core for some time, will allow us to focus entirely on our growth objectives in the MOR and our stated intention of exceeding our 500,000m3 per month processing target. Our short-term priority is the completion of the acquisition and integration of the Remhoogte/Holsloot Project into our current business. We are also progressing with our exploration programme to increase Rockwell's resources and mining flexibility. We intend developing 3 to 4 million m3 of Rooikoppie Exploration Targets at Lanyonvale and will be carrying out further pitting of the Rooikoppie gravels at Wouterspan with the goal of growing Rockwell's profitable operational base for the future."
