FORT LAUDERDALE, Fla.--(BUSINESS WIRE)--Feb. 9, 2004

Leading Mining Company Uses Citrix Access Infrastructure

to Provide Easy Access to Applications, Improve Productivity

and Simplify IT Administration

Citrix Systems, Inc. (Nasdaq:CTXS), the global leader in access infrastructure solutions, today announced that Diavik Diamond Mines Inc. (DDMI), a Canadian mining company, is using Citrix(R) MetaFrame(R) Presentation Server to provide employees with access to key business applications, regardless of whether they are working in the corporate office or out in the remote wilderness of the Northwest Territories.

When diamonds were discovered in the Canadian Arctic in 1991, many considered the area to be nearly inaccessible. But today the Northwest Territories is the site of one of the most extensive mineral rushes in North American history. DDMI's primary asset is a majority interest in the Diavik Diamond Mine, a large tract of land that hosts the Western Hemisphere's second diamond mine, over 300 kilometers northeast of Diavik's headquarters in Yellowknife, Northwest Territories. Because DDMI's operations are often spread across great distances, secure, easy and instant access to information is key to the success of its mobile workforce. DDMI is using MetaFrame Presentation Server to deliver information, processing capabilities and high-use business applications to a variety of contractors and engineers via satellite link, regardless of their location. With anywhere, anytime access to critical information, DDMI is able to improve productivity and communication across great distances.

"Workforce mobility is imperative to the success of this mine," said Peter Heine, information technology manager at DDMI. "With over 500 employees and independent contractors across three offices in Yellowknife and the mine site, DDMI places the utmost emphasis on helping our employees and partners stay connected to key business applications and to each other. Citrix access infrastructure is helping ensure that we achieve our business objectives."

DDMI chose Citrix because of its ability to deliver reliable, cost-effective and secure access to corporate applications while making the most of existing bandwidth connections. Using MetaFrame Presentation Server, DDMI provides access to applications including Mincom Ellipse(TM) Asset Management software, staff scheduling software from Schedule-HR, TABS travel and accommodation booking system from Team Technology, time-sheet entry, and e-mail. This process has dramatically reduced the time and costs required to deploy and maintain applications.

The foundation of the Citrix MetaFrame Access Suite, Citrix MetaFrame Presentation Server, is the world's most widely deployed presentation server for centrally managing heterogeneous applications and delivering their functionality as a service to workers, wherever they may be. MetaFrame Presentation Server is certified to run on Microsoft(R) Windows(R) 2000 Server and Windows Server(TM) 2003, and supports virtually any custom or commercially packaged Windows application. MetaFrame Presentation Server provides an exceptional foundation to build highly scalable, flexible, secure, manageable access solutions that reduce computing costs and increase the utility of any information system.
