Northern Peru Intersects 56m @ 2.63g/t Gold in Step Out Drilling at Hilorico

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 3, 2006) - Northern Peru Copper Corp. (TSX:NOC) is pleased to announce results from the latest three holes at its Hilorico gold prospect located in northern Peru approximately one kilometre from the company's major Galeno copper-gold-molybdenum porphyry deposit and 16km from Yanacocha, South America's largest gold mine.

Hole HR-06-05a returned 56m grading 2.63 g/t gold and 2.6 g/t silver from 138m to 194m in completely oxidised, brecciated quartzite and included 19.7m grading 6.78 g/t gold and 3.9 g/t silver and 2m grading 41.9 g/t gold. HR-06-05a is a 100m step out hole to the north of the discovery hole HR-05-01 which cut 201m @ 1.00 g/t gold and 5.6 g/t silver.

Although it is early days in the exploration of this significant new gold zone at Hilorico, Northern Peru believes that HR-06-05a cut a high-grade gold feeder structure with an envelope of gold mineralization that continues to the north where HR-06-03 stepped-out a further 80m and returned 82.5m at 0.70 g/t gold and 2.2 g/t silver from 40m to 122.5m. To the south HR-06-04 intercepted 70m grading 0.41 g/t gold and 10.2 g/t silver from 40m to 110m. Both intervals comprise oxidised, brecciated quartzites.

Marshall Koval, President & CEO, said: "The gold zone at Hilorico remains open in all directions and we are very excited about the potential to expand it further. Northern Peru will continue to aggressively drill Hilorico in 2006 while we also advance our Galeno deposit with active drilling, engineering and economic evaluation."

The new results from the three core holes HR-06-03, 04 and 05a are listed below. HR-06-05a was re-drilled after the original hole (HR-06-05) was lost at 71m due to caving. Assay results from the first 71m of the two holes compare well.

Drill hole locations are shown on the map below with the bolder line highlighting the longest intercept reported for each hole which is shown in bold in the table. Also shown is core hole DDH-GN-47 which was drilled by North Limited in 1998 and returned 30 metres grading 1.57 g/t gold and 3.5 g/t silver from 98 to 128 metres. Northern Peru is not aware of any QA/QC data relating to results from this drill hole, they are historical in nature and should not be relied on.

Marshall Koval, P.Geo, is the Qualified Person as defined by National Instrument 43-101 for the Galeno Project. Jeff O'Toole, a geologist with over 25 years of experience is supervising the quality control and quality assurance program on site. Logging and sampling are completed in Northern Peru's secure facility located at the project. The drill cores are mechanically split on site and samples are transported to the ALS Chemex facility in Lima for sample preparation and analysis. Northern Peru inserts standards, blanks and duplicates selected on a random basis into the sample stream and sends 5% of the sample pulps to check laboratories in Vancouver.
