Appleton to Change Name to Cornerstone Metals Inc. ("CCC") and Complete Share Consolidation

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 31, 2012) - Appleton Exploration Inc. (TSX VENTURE:AEX) (the "Company") announces that the TSX Venture Exchange (the "Exchange") has approved the Company's share consolidation on the basis of one (1) post-consolidation Common Share for every five (5) pre-consolidation Common Shares (the "Share Consolidation") and the name change to "Cornerstone Metals Inc." (the "Name Change"). The Share Consolidation and Name Change will be completed effective June 1, 2012 (the "Effective Date"). The Share Consolidation and Name Change were approved by shareholders at the Company's Annual General Meeting held on July 19, 2011. The Company's Common Shares will begin trading on the Exchange on a consolidated basis under its new name Cornerstone Metals Inc. at the market open on Friday, June 1, 2012, under the new trading symbol "CCC". The new CUSIP for the Company's post-consolidation Common Shares is 21925M109. The 49,357,671 pre-consolidation Common Shares of the Company will be reduced to approximately 9,871,534 post-consolidation Common Shares. If the Share Consolidation would otherwise result in the issuance of a fractional Common Share, no fractional Common Shares will be issued and each fractional Common Share remaining after consolidation that is less than one-half of a share will be cancelled and each fractional Common Share that is at least one-half of a Common Share will be changed to one (1) whole Common Share. The exercise or conversion price and the number of Common Shares issuable under any of the Company's outstanding warrants and stock options will be proportionately adjusted to reflect the Share Consolidation.

The Company has retained its transfer agent, Computershare Investor Services Inc. ("Computershare") to act as the exchange agent for the Share Consolidation. Shareholders of record as at the Effective Date will receive a letter of transmittal providing instructions for the exchange of their Common Shares as soon as practicable following the Effective Date. To receive share certificates representing the post-consolidation Common Shares, registered shareholders will be required to send their share certificates representing pre-consolidation Common Shares, along with a properly executed letter of transmittal, to Computershare, in accordance with the instructions provided in the letter of transmittal. Additional copies of the letter of transmittal may be obtained from Computershare by calling 1-800-564-6253. Non-registered shareholders who own Common Shares in book-entry form do not need to take any actions to exchange their pre-consolidation book-entry Common Shares for post-consolidation Common Shares. Upon the Effective Date, each then existing book-entry account will be adjusted to reflect the number of post-consolidation Common Shares to which the non-registered shareholder is entitled.

Courtney Shearer, CEO, said, "We believe that the consolidation of shares will position the Company to attract new projects and provide a share structure that can create share growth and liquidity going forward in these difficult financial markets." Shearer added, "The new name of the Company reflects our goal of becoming a developer/producer in the mining industry."

The Company currently owns the Dora gold project, located near Merritt, BC and is actively seeking more advanced stage mineral projects, either late-stage exploration or past-producers, that can be developed to production.

On Behalf of the Board of Directors,

Courtney Shearer, Interim President and CEO
