Norsemont Announces Further Drill Data on the Amata Project of 2M (at) 783 g/t Ag & 2M (at) 3.08% Cu & 41.95M (at) 61.3 g/t Ag, 0.24 g/t Au

Norsemont Announces Further Drill Data on the Amata Project of 2M (at) 783 g/t Ag & 2M (at) 3.08% Cu & 41.95M (at) 61.3 g/t Ag, 0.24 g/t Au

VANCOUVER, Canada, September 13/PRNewswire/ -- Norsemont Mining Inc. ("Norsemont") (TSX-V: NOM; Frankfurt: A0DQKK) is
pleased to announce further details on its recently acquired Amata
Silver-Gold-Copper project from Rio Tinto Mining and
Exploration Ltd. ("Rio Tinto") (NYSE: RTP) as previously announced on
September 9, 2005. Norsemont has acquired a 100% interest in the Amata Project
(10,300 hectares) located 50km NE of Arequipa City in southern Peru.

The Amata high sulphidation epithermal system and associated porphyries
are located in the Cordillera of southern Peru. Sampling of 3,078 rock chip
and grab samples include anomalies grading up to 2,400 g/t of silver and up to
7.2 g/t of gold, to values below detection.

In 2002 and 2003 Rio Tinto completed a two-staged drill program
consisting of 15 widely-spaced holes (within 2km), of which the most
encouraging results include:

Cerro Amata:
AM-01 : 317.80m (at) 31.7 g/t Ag, 0.11 g/t Au

Includes: 41.95m (at) 61.3 g/t Ag, 0.24 g/t Au
48.10m (at) 36.7 g/t Ag, 0.28 g/t Au

AM-02 : 100.25m (at) 1.11% Cu, 0.16 g/t Au ,19.55 g/t Ag

AM-03 : 2m (at) 3.08% Cu, 12.85 g/t Ag
2.35m (at) 0.80% Cu, 22.5 g/t Ag

AM-04 : 118m (at) 0.11 % Cu, 13.08 g/t Ag

Includes: 4m (at) 52.45 g/t Ag

AM-05 : 2m (at) 783 g/t Ag, 0.14% Cu

Tincachoca:
TQ-02: 26.8 m (at) 2.6% Cu, 0.42 g/t Au, 45 g/t Ag

Tacune:
TN-01: 22.2m (at) 0.047% Mo, 0.01 g/t Au
13.75m (at) 0.039% Mo, 0.03 g/t Au
TN-02: 3.95m (at) 0.09% Mo
TN-03: 64m (at) 0.33 % Cu

Based on alteration mapping and surface geochemistry, six principal
targets have been identified (Cerro Amata, Tincachoca, Cayrane, Tacune,
Trinchera and Palcamayo) that vary from about 15 hectares (500 m x 300 m) to
120 hectares (1.2 km x 1 km) in size. The Cerro Amata target contains a
central diatreme breccia body that has a surface dimension of approximately
600 x 300 m. North of Palcamayo and the Apacheta (7th target) sector are yet
to be explored. Norsemont believes there is potential to expand the zones of
mineralisation and identify additional zones of high grade precious metals in
the epithermal lithocap or copper in the underlying porphyry.

The oldest rocks in the area correspond to rocks of the coastal batholith
(544Ma) which are overlain by Yura group sediments. The prospect is situated
within the volcanic complex of Cerro Blanco-Cerro Saltaoco in the Barroso
group (Pleistocene) which border the batholith and overly the Yura group. The
prospect was identified during the follow up of TM colour anomalies. The
anomaly corresponded to a large volcanic complex with four volcanic edifices
aligned NE-SW over an area of 10 x 4km. Yanacocha Au-Ag district (Yanacocha
Mine in northern Peru) and Amata district are similar systems, showing
characteristics of epithermal Au and Ag in the upper levels and underlying
porphyry Cu. Both are upper Tertiary age deposits with similar structural
controls.

Norsemont continues to make substantial progress with the 2005 drill
program at its flagship Constancia project. Norsemont is also pleased to
announce it has acquired additional data with regards to the previous drilling
Mitsui conducted in the San Jose high grade zone. To date, ten diamond drill
holes have been completed. Core samples have been sent to the ALS Chemex
laboratory in Lima, Peru, for analysis, and results will be released as they
are made available and reviewed by Norsemont's geological team.

Henricksen P. Geo., Norsemont's Consulting Geologist and Qualified Person as
defined by NI 43-101.
