2006 Drilling at Northern Peru's Pashpap Property is Doubled to 4,800m by JOGMEC and Land Position Expanded

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 10, 2006) - Northern Peru Copper Corp. (TSX:NOC) is pleased to announce a 2006 drill program of 4,800m at Pashpap, more than twice the 2005 meterage, as well as the staking of new exploration targets that double the size of the claims in the joint venture. Pashpap has been operated by Japan Oil, Gas and Metals National Corporation ("JOGMEC") since March 2005 under an option agreement to earn 51% from Northern Peru.

A summary of the key developments over the past nine months of the joint venture is provided below:

- In 2005 JOGMEC spent US$ 739,000 on exploration including 1,852m of drilling in six diamond drill holes, three kilometres of new road construction and extensive geological mapping and geochemical sampling.

- All drill holes contained significant sulfide mineralization and confirm the presence of a cluster of coalescing porphyry copper systems at Pashpap of at least seven kilometres in diameter, within which extensive areas remain untested by drilling.

- Additional staking of new exploration targets in the Pashpap district has more than doubled the size of the property from 4,823 hectares to 10,987 hectares. The enlarged property remains 100% owned by Northern Peru and is subject to the JOGMEC earn-in agreement.

- JOGMEC have approved a 4,800m diamond drill programme on new exploration targets that is budgeted at US$ 1,200,000 and scheduled to commence in May 2006.

Pashpap is an advanced exploration project situated in the Ancash Department of Peru where the Pierina gold mine (100% Barrick) and the Antamina copper-zinc mine (Noranda Inc 33.75%, Billiton Base Metals 33.75%, Teck-Cominco 22.5% and Mitsubishi Corporation 10%) are also located.

Further updates will be issued as significant results are received.
