NiMin Energy Announces Entering Into of Definitive Agreement for Sale of California Assets

CARPINTERIA, CALIFORNIA--(Marketwire - April 27, 2012) - NiMin Energy Corp. (TSX:NNN)(OTCBB:NEYYF)(OTCQX:NEYYF) (the "Company" or "NiMin") today announced that it and its wholly-owned subsidiary, Legacy Energy, Inc. ("Legacy"), have entered into a definitive agreement (the "California Agreement") for the sale of its assets in California's San Joaquin Basin (the "California Assets") to Southern San Joaquin Production, LLC for a total cash consideration of approximately US$27 million, subject to adjustment. The sale of the California Assets is subject to customary closing conditions, including approval by NiMin shareholders for the sale of all or substantially all of the assets of the Company (the "Asset Sales").

Asset Sales and Proceeds

The sale of the California Assets is in addition to the recently announced sale of the Company's assets in Wyoming's Big Horn Basin (the "Wyoming Assets") resulting in combined gross proceeds of approximately US$125 million, subject to adjustment.

Macquarie Tristone was the exclusive advisor to NiMin and Legacy in connection with the sale of the Wyoming Assets and the California Assets.

The Company will proceed with the Asset Sales and the liquidation and dissolution of NiMin and Legacy upon receipt of all required regulatory and shareholder approvals. After the payment of the liabilities of NiMin and Legacy which are currently estimated to be between approximately US$52.6 to US$55.1 million, NiMin intends to distribute the net proceeds of the liquidation and dissolution of both corporations to NiMin shareholders in one or more distribution installments. Upon completion of the asset sales, the net proceeds available for distribution are currently estimated to be between US$70.3 million to US$72.8 million. Although management of the Company believes that the estimates of the liabilities and net proceeds for distribution set forth above are reasonable based on information currently available to the Company, the actual amounts of such liabilities and resulting net proceeds available for distribution may differ materially from the estimates presented above, thereby affecting the amount of cash available to be distributed to shareholders. The board of directors of the Company (the "Board") is not currently aware of any material items that could give rise to unforeseen tax liabilities or other liabilities or costs which would materially reduce the amount of cash available for distribution to shareholders, but there is no assurance this will remain the case.

Annual and Special Meeting

The Company is preparing a management information circular/proxy statement (the "Circular") for provision to shareholders in respect of an annual and special meeting of shareholders (the "Meeting") to seek approval for: (i) the Asset Sales; (ii) the wind up and dissolution of the Company; (iii) annual meeting matters, including the election of the Board and the appointment of an auditor; (iv) approval of the unallocated options under the Company's stock option plan; and (v) the advisory vote on compensation payable to executives as a result of the sale of assets. It is currently anticipated that the Meeting will be held on or before June 27, 2012. The approval of the Asset Sales is not conditional upon the approval of the wind up and dissolution of the Company.

Support Agreements

Directors and senior officers of the Company who hold an aggregate of 3,581,342 common shares (representing approximately 5.13% of the issued and outstanding common shares) and options to purchase 3,925,000 common shares of the Company, have entered into support agreements pursuant to which such holders have agreed to vote in favour of the resolution to be placed before shareholders at the Meeting to approve the Asset Sales.

Further Information

Further information regarding the mailing of the Circular, the timing of the Meeting, the liquidation and dissolution of the Company and the amount and timing of distributions to shareholders will be provided in subsequent press releases as such information becomes available.
