    TSX-V: ACT

    TORONTO, June 29 /CNW/ - Active Control Technology Inc. (TSX-V:ACT)
announced today that ActiveMine(TM), a two-way voice communications and
tracking system that operates on a 100% wireless Wi-Fi network, has been
approved by West Virginia's Office of Miners' Health, Safety and Training.
    The West Virginia agency is the first government regulator to certify
that ActiveMine is fully functional in accordance with new safety rules
requiring emergency communications and tracking systems in underground coal
mines. The agency's technical reviewers have verified that the technology,
which was developed for all types of mining environments, meets West Virginia
performance and safety standards. An independent engineer also confirmed
ActiveMine's capabilities and witnessed it operating in a producing
underground coal mine, as part of the approval process.
    The certification means that ActiveMine is approved for sale in West
Virginia, the leading state for underground coal mining and safety. Under West
Virginia rules, only approved communications and locating systems can be
included in mine safety plans, which must be submitted by mine operators by
the end of next month. The systems must be installed in all of the state's
more than 150 underground coal mines by July 31, 2008.
    ACT has also submitted applications seeking "intrinsically safe" (IS)
certification by the federal Mine Safety and Health Administration (MSHA),
which requires that all underground coal mine communications and tracking
systems be spark-proof. ActiveMine was designed to meet all relevant federal
and state mine safety regulations, including the requirement for two-way voice
communications and not just text messaging, as set out by MSHA.
    "Underground coal mine operators can now be confident that ActiveMine
delivers the communications and locating performance required under West
Virginia's tough safety rules," said Steve Barrett, President and CEO, ACT.
"We have the technology and infrastructure in place to help them meet the
regulations on time."
    Barrett added, "In addition to the safety aspect, our system provides
mine operators with powerful tools to improve their day-to-day operations and
bottom line results."
    ActiveMine offers exclusive features and benefits that are not currently
provided with other commercially-available mine communications and tracking
systems. It is the only wireless system that:

    1.  Is designed to meet federal MINER Act requirements for wireless
        systems as established in MSHA policies.
        According to the Administration's Program Policy Letter No. P06-V-10,
        "MSHA interprets the term 'wireless,' as used in the MINER Act, to
        mean that no wired component of the system exists underground where
        it may be damaged by fire or explosion. Post-accident communication
        technology would be considered acceptable if, based on its location
        in the mine and the history of mine explosions and fires in the mine,
        it is likely to withstand the event intact." (Refer to:

    2.  Is less susceptible to mechanical damage from rock fall, vehicles and
        other incidents because it uses a 100% wireless Wi-Fi network
        backbone (also known as a "backhaul").
        ActiveMine's 5.8 GHz wireless nodes (also known as 'routers' or
        'access points') communicate with one another without hardwire
        connection. This is in contrast with other available systems, which
        use hard-wired leaky feeder or Ethernet backbones.

    3.  Is capable of providing high-speed and high-bandwidth data
        communications to enhance productivity.
        In addition to 2.4 GHz wireless two-way voice communications and
        tracking, the ActiveMine network supports data services, including
        streaming video, to monitor mine activities from the surface and
        improve operating efficiency. By comparison, devices linked to most
        leaky feeder systems can typically only transmit low-speed and
        low-bandwidth data.

    4.  Uses open-standard technology that is fully compatible with most
        other mine communications and tracking technologies, including
        previously installed systems. This makes it possible for mines to add
        wireless features using ActiveMine while leveraging hardwire networks
        already in place.

    5.  Provides all of these enhanced capabilities at a lower 'Total Cost of
        Ownership' than "leaky feeder and RFID gates" (the combination of
        leaky feeder communication systems with locating via RFID gates).
        This is possible because labor costs for installation and maintenance
        of ActiveMine are lower than for all other available systems. Also
        the technology is built to cost-effective "intrinsically safe"
        standards, in keeping with MSHA rules.

    "We're confident that ActiveMine's lower Total Cost of Ownership, along
with the operating efficiencies it makes possible, will be the primary drivers
for purchases of the system," Barrett said. "West Virginia's regulatory
approval opens the door to make those purchases possible in the state."
    ActiveMine's unique communications and data network enables monitoring of
production, personnel and equipment in all types of surface and underground
mining environments including coal and base metal mines.
