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
February 2010.

Over the six month period to 30 November 2009, the Company's shares have traded
at an average premium to Net Asset Value ('NAV') of 1.78%. Upon due
consideration of this fact, the Board has concluded that it is not in the
interests of shareholders as a whole to implement a semi-annual tender offer in
February 2010.

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