NIMIN ENERGY TO VOLUNTARILY DELIST

FROM THE TORONTO STOCK EXCHANGE

AND TRANSFER LISTING TO NEX

Carpinteria, CA – October 10, 2012 – NiMin Energy Corp. (TSX:NNN) (the “Company” or “NiMin”) announces that its common shares will be voluntarily delisted from the Toronto Stock Exchange (“TSX”) after the close of trading on October 22, 2012 (the date on which NiMin’s initial distribution will be payable as announced on September 24, 2012 and further detailed on September 28, 2012) and its listing will be transferred to the NEX, a separate board of the TSX Venture Exchange, effective as of market open on October 23, 2012. From and after October 23, 2012, NiMin’s common shares will trade on the NEX under the symbol “NNN.H”.

As described in NiMin’s management information circular dated May 23, 2012, the common shares are being voluntarily delisted from the TSX as NiMin is no longer able to meet the TSX’s listing requirements following the sale of substantially all of its assets as previously announced. NiMin’s common shares will be listed on the NEX in order to maintain liquidity during the Company’s voluntary liquidation and dissolution process; however, NiMin cannot give any assurance that an active or liquid market for its common shares will develop or be sustained.
