("Astar" or the "Company")

Operating Agreement with Aggregates West, Inc

Astar Minerals plc ("Astar" or the "Group") (AIM: ASTA), an operator of quarries in British Columbia announces that it has signed heads of terms with Aggregates West, Inc. and Valley View Sand and Gravels, Inc, (collectively "Aggregates West"), to operate a number of quarries based in an area between the US/Canadian border and Seattle.

Aggregates West has a number of sites with high quality reserves of sand and gravel and either owns or has access to over 10 million tons of materials. For the year to 31 December 2011, Aggregates West had turnover of over C$9 million.

Under the agreement, Astar intends to take over the management of the operations of Aggregates West which currently comprises a number of operating sites with substantial reserves in the attractive and fast growing area of the US between Seattle and the Canadian/US border. As part of the agreement, Astar will pay royalties to Aggregates West based on sales volumes. The agreement will run for an initial period of three years with Astar having the option to renew the agreement for a further three years.

Aggregates West's operations are geographically complimentary to Astar's current operations. Astar's existing business and operations will benefit from access to a significantly larger sales operation and the ability to sell a wider range of products to its existing client base. In particular, the enlarged group will be well placed to develop business with the producers of ready mixed concrete and other high margin products. David Grainger, one of the owners of Aggregates West, will be joining the Astar management team bringing his considerable knowledge of the aggregates and construction industries.

As part of the agreement, Astar will purchase additional equipment and inventory, build up working capital and invest in developing further some of Aggregates West's existing sites. The Company has already raised C$350,000 of the required funding through debt finance locally in Canada.

It is expected that the management agreements with Aggregates West, Inc. will be signed shortly.

Further announcements will be made in due course.

Lynda Chase-Gardener, Chairman said:

"The agreement with Aggregates West represents a quantum leap in both the scale of operations, revenues and access to reserves for Astar. The existing Aggregates West business also offers a number of exciting opportunities for growth in the Vancouver and Lower Mainland area of British Columbia and North West Washington State. Furthermore, there are a number of areas of synergy between the businesses which make the combination financially attractive."
