ROLLOVER OF DISCOVERY 2008 FLOW-THROUGH LIMITED PARTNERSHIP ASSETS

TORONTO, Sept. 9 /CNW/ - Middlefield Mutual Funds Limited (the "Mutual Fund") announced today that, in connection with the planned dissolution of Discovery 2008 Flow-Through Limited Partnership ("Discovery 2008" or the "Partnership", cusip: 25469M102), it is proposing to transfer all of the assets of Discovery 2008 to the Precious Metals Class (MID170) of Middlefield Mutual Funds Limited in exchange for mutual fund shares having the same aggregate net asset value as that of the Partnership. The record date for the transfer is September 9, 2010 and the liquidity date is October 15, 2010. These dates have been accelerated from the dates disclosed in the Discovery 2008 prospectus to enable those Discovery 2008 investors who wish to invest in our Discovery 2010 Flow-Through Limited Partnership ("Discovery 2010") to be able to do so. Discovery 2010 will have its closing in late October, 2010. Appropriate elections under applicable income tax legislation will be made to effect the transfer on a tax-deferred basis.

It is currently intended that Discovery 2008 will be dissolved on or about October 15, 2010. Investors will then be able to redeem their Precious Metals Class (MID170) shares, retain them for longer-term growth or switch tax-free into any of the other Mutual Fund classes. Remaining invested in the Mutual Fund avoids incurring the capital gains tax liability that arises upon redemption of the Mutual Fund shares.

There are nine available asset classes within the Mutual Fund, providing significant flexibility to suit numerous investment objectives including safety of capital, income and growth. The Classes currently offered are Groppe Tactical Energy, Short-Term Income, Income Plus, Uranium Focused Metals, Income and Growth, Canadian Growth, Equity Index, Global Agriculture and Precious Metals. We are pleased to report that, within the Class funds, the Income Plus Class and the Precious Metals Class have received 5-star ratings from Globefund (July 31, 2010).

Investors should consult their advisors to determine the strategy that is most suitable for them for the achievement of their own personal needs and objectives.
