Norsemont Intersects 1.58% Copper in Step-Out Drilling at the Constancia Project

Vancouver, Canada (ots/PRNewswire)

Norsemont Mining Inc.
("Norsemont" or "the Company") (TSX-V: NOM; Frankfurt: N8S; WKN:
A0DQKK; OTC-BB: NOMFF; ISIN: CA6565291045) is pleased to announce
results from the fourth and fifth Phase II diamond drill holes
targeting the Constancia Zone at the Constancia
Copper-Molybdenum-Silver-Gold Porphyry Project in southern Peru.

Drill hole CO-06-045 is a step-out hole in the north-central part
of the Constancia zone. The upper part of the hole contained a
combination of post-mineral dike and leached capping to 150 meters,
below which secondary chalcocite mineralisation was encountered in
monzonite. This mineralisation is in a step-out area that was
previously thought to be beyond the boundary of the mineralised zone,
based on the surface geology.

Drill hole CO-06-046 is an infill hole in the southern part of the
Constancia zone. The hole commenced in skarn mineralisation to
approximately 93 meters. Below 93 meters, leached capping and
secondary chalcocite was encountered to below 200 meters. The 200
meter interval represents skarn sulfides and secondary chalcocite
mineralisation, typical of this part of the Constancia zone, which is
open-ended to the south.

Note 1: Copper equivalent Values (CuEQ) are estimated using
long-term metal prices including: Copper US$1.20 per lb, Molybdenum
US$8.00 per lb, Gold US$450 per oz., and Silver US$7.50 per oz.
Adjustment factors to account for differences in relative
metallurgical recoveries for gold, copper and molybdenum will depend
upon the completion of definitive metallurgical testing. CuEQ equals
Cu per cent plus Mo percent times (8.00/1.20) plus Au grams per tonne
times 14.47/(1.20(x)22.05) plus Ag grams per tonne times
0.24/(1.20(x)22.05).

The majority of future holes will be step-out holes on 100 meter
centers, similar to the program carried out in 2005, for the purpose
of calculating a resource estimate for the property. Two drill rigs
are currently operating on site.

Marc Levy, Norsemont President & CEO, stated, "As with the results
reported late last week, this infill hole continues to show excellent
continuity within the mineralised zone. The copper grades in the
step-out hole are some of the highest continuous grades of copper in
chalcocite encountered to date."

The drilling program and geological studies at the Constancia
project are being supervised by Dr. Thomas A. Henricksen, P. Geo.,
Norsemont's Qualified Person as defined by NI 43-101. Mr. Henrickson
has reviewed and approved information contained in this news release.
Core samples are cut with a diamond saw, with one-half of the core
placed in sealed bags, and shipped to ALS Chemex Assay Labs in Lima,
Peru. The program includes an extensive quality control program for
assaying which includes the systematic use of standards, blanks, and
field duplicate samples. Secondary laboratories are also used for
check assaying.

A plan map with drill hole locations will be available shortly on
Norsemont's website at www.norsemont.com
