Tender Offer

The Board of BlackRock Commodities Income Investment Trust plc (the "Company")
today announces its decision not to proceed with a semi-annual tender offer in
August 2009.

Over the six month period to 31 May 2009, the Company's shares have traded at
an average discount to Net Asset Value ("NAV") of 0.01% which is less than the
discount of 2% to NAV, the price at which any tender offer would be made. Upon
due consideration of this fact, the Board has concluded that it is not in the
interests of shareholders to implement a semi-annual tender offer in August
2009.

The Board will continue to monitor the level at which shares in the Company
trade relative to the NAV.
