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

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
