Re:  Former Pacific Copper properties in Chile

Gentlemen:

Sociedad Gareste Limitada (“Gareste”) is the contractual Operator for Pacific
Copper Corp. (“Pacific”) in Chile under the Operator Agreement dated February
12, 2008 with Pacific Copper Chile Ltda., Pacific’s subsidiary in the country of
Chile.

As you know, Pacific, due to a lack of funding, has been unable to pay the taxes
and other maintenance expenses for most of the mineral concessions owned by
Pacific in Atacama Region III, Chile, and subject to the Operator Agreement. As
a consequence, many of these properties have “lapsed” and Pacific no longer has
legal title to such concessions.

In a large number of these cases, however, Gareste was able to file and
“relocate” mining concessions to replace the titles lost by Pacific, as more
specifically shown in Exhibit A attached hereto.

This letter is to confirm that the concessions depicted on Exhibit A were
relocated by Gareste in trust and for the benefit of Pacific. Further, that PCC
is indebted to Gareste in the amount of $ 35,000 for preserving said
concessions. The parties will at the appropriate time arrange for the
reconveyance of said titles back to Pacific, at which time Pacific will
reimburse Gareste for these out of pocket expenses, and further, will grant to
Gareste a 2% Net Smelter Return (“NSR”)royalty on production from these
concessions, capped at the amount of US$6 million on a per property basis, with
repurchase rights in PCC for one-half of the NSR royalty (an undivided 1%),
again on a per property basis, for the sum of US$2 million.

If you agree with these matters, please sign where indicated below and return
one fully-executed original to the undersigned.

Very truly yours,

SOCIEDAD GARESTE LIMITADA
