======================================================================

Vancouver, British Columbia, Canada, May 24, 2007, Peru Copper Inc.
(TSX:PCR / AMEX:CUP / BVL:CUP) ("Peru Copper" or the "Company")
announced today that it has entered into an exclusivity agreement with
a third party in order to facilitate discussions with such third party
regarding a potential transaction which may involve the acquisition of
the Company or other material transactions. The exclusivity period ends
on May 28, 2007. There is no certainty that agreement on a transaction
will be reached and Peru Copper will provide further updates at the
appropriate time.

Peru Copper is involved in the acquisition and exploration of
potentially mineable deposits of copper in Peru. On June 11, 2003, Peru
Copper entered into the Toromocho Option Agreement ("Toromocho Option")
with Empresa Minera del Centro del Peru S.A. ("Centromin"), a Peruvian
state-owned mining company, whereby Centromin granted the Company the
option to acquire its interest in the mining concessions and related
assets of the Toromocho Project.

Cautionary Note to U.S. Investors---The United States Securities and
Exchange Commission permits U.S. mining companies, in their filings
with the SEC, to disclose only those mineral deposits that a company
can economically and legally extract or produce. We use certain terms
in this press release, such as "mineral deposit", that the SEC
guidelines strictly prohibit U.S. registered companies from including
in their filings with the SEC. U.S. Investors are urged to consider
closely the disclosure in our Form F-3 Registration Statement, File No.
333-121527, which may be secured from us, or from the SEC's website at

This news release contains "forward-looking statements" within the

the future price of copper and molybdenum, the timing of exploration
activities, the mine life of the Toromocho Project, the economic
viability and estimated internal rate of return of the Toromocho
Project, the estimation of mineral reserves and mineral resources, the
results of drilling, estimated future capital and operating costs,
future stripping ratios, projected mineral recovery rates and Peru
Copper's commitment to, and plans for developing, the Toromocho
Project. Generally, these forward-looking statements can be identified
by the use of forward-looking terminology such as "plans", "expects" or
"does not expect", "is expected", "budget", "scheduled", "estimates",
"forecasts", "intends", "anticipates" or "does not anticipate", or
"believes", or variations of such words and phrases or state that
certain actions, events or results "may", "can", "could", "would",
"might" or "will be taken", "occur" or "be achieved". Forward-looking
statements are subject to known and unknown risks, uncertainties and
other factors that may cause the actual results, level of activity,
performance or achievements of Peru Copper to be materially different
from those expressed or implied by such forward-looking statements,
including but not limited to: risks related to the exploration and
potential development of the Toromocho Project, risks related to
international operations, the actual results of current exploration
activities, conclusions of economic evaluations, changes in project
parameters as plans continue to be refined, future prices of copper,
silver, molybdenum and gold, as well as those factors discussed in the
section entitled "Risk Factors" in the Form F-3 as on file with the
Securities and Exchange Commission in Washington, D.C. and in the
section entitled "Narrative Description of the Business -- Risks of the
Business" in the Annual Information Form of the Company dated March 24,
2005. Although Peru Copper has attempted to identify important factors
that could cause actual results to differ materially from those
contained in forward-looking statements, there may be other factors
that cause results not to be as anticipated, estimated or intended.
There can be no assurance that such statements will prove to be
accurate, as actual results and future events could differ materially
from those anticipated in such statements. Accordingly, readers should
not place undue reliance on forward-looking statements. Peru Copper
does not undertake to update any forward-looking statements that are
incorporated by reference herein, except in accordance with applicable
securities laws.
