Pan Pacific Copper Gears Up to Feasibility Study Phase in Development Project of Quechua Copper
Deposit in Peru

Pan Pacific Copper Co., Ltd. (“PPC”), jointly owned by Nippon Mining & Metals Co., Ltd. andMitsui Mining & Smelting Co., Ltd. has since January 2009 been conducting its pre-feasibility study(“Pre-FS”) for the development project of the Quechua Copper Deposit in Peru, including economic
evaluation based on conceptual engineering and production planning designs, as well asimprovement in the accuracy of resource estimation by additional exploratory drillings. As a resultof recent review of the evaluation report, it was expected that the project would be economicallyviable, so that PPC has decided to move the project into the feasibility study (“FS”) stage.

Under the contemplated FS, to be conducted between December 2009 and January 2011, PPC will
improve the accuracy of the final resource estimation, provide basic engineering of facilities, obtainenvironmental approvals, and estimate the development costs and profitability, in order to reach thefinal decision whether full-scale development will be made.

At present, this project is estimated to have 17 years of mine life and produce a total of 1,300,000
tons (76,000 tons per annum) of copper. The copper concentrate produced by this project isscheduled to be shipped to the PPC Group smelters.

The project, combined with the Caserones copper and molybdenum deposit development project inChile, is expected to enable PPC to increase its equity volume ratio of copper concentrate from 18%
to over 50% securing stable supply of raw materials for its smelting operations. PPC is committed tocontributing to a stable supply of resources.

An outline of the Quechua copper deposit development project (estimated) is as follows:

1. Outline of the FS
A. Period:
From December 2009 to January 2011, for 14 months
B. What to be Done
Conduct additional exploratory drillings, estimate resource and ore reserve, pursue possibility
to recover molybdenum, conduct flotation tests in a laboratory and a pilot plant, set design
parameters, design basic facilities, estimate investment costs, obtain governmental approvals
on development and environmental impacts, and others.
C. CostApproximately ¥3 Billion

2. Outline of the Entire Project (estimated)
A. Location:
The Quechua Copper Deposit is located in the district of Espinar in Cuzco Province, 700km
southeast of Lima. The region is at an altitude in the range of 4,000m-4,400m.

B. Area of Mining Concessions:
5,732 hectares
C. Resources:
Approx. 680 million tons with an average copper grade of 0.38%(@ cut-off grade of 0.25%copper)
D. Work Plan and Schedule:
Dec. 2009 to Jan. 2011

Conducting the feasibility study.

Oct. 2010 to May 2011

Obtaining environmental approvals.

June 2011 to July 2014

Constructing mine and ore processing facilities.

Aug. 2014

Starting the operation
17 years mine life, extending to 2030 and producing approximately
270,000 tons of copper concentrate per annum (equivalent to60,000 tons of copper per annum)

E. Estimated Initial Investment
Approx. US$ 850 million
F. Financing:
The preliminary survey, the Pre-FS, and the FS will be financed by the issuance of new shares,
which will be underwritten by the joint-parent companies of PPC.
