    VANCOUVER and LIMA, Peru, Oct. 22 /CNW/ - Norsemont Mining Inc. ("the
Company") (TSX: NOM, BVL: NOM) today announced results (Table 1 below) from
the ongoing Phase III drill program at the Constancia copper-molybdenum-silver
porphyry project in southern Peru.
    Norsemont currently has six drill rigs on site and has completed more
than 17,000 meters of drilling on the Constancia project thus far during 2007.
Since the last resource estimate reported by Snowden and Associates and
disclosed on March 29, 2007, the majority of this drilling has been infill
drilling.
    Commenting on the results, Norsemont's President Bob Baxter said: "Our
Constancia drilling program continues to return excellent results. With six
drill rigs now active on site we expect to complete our infill drilling
program on schedule."
    The drilling program and geological studies at the Constancia project are
being supervised by Leonardo Diaz (MAusIMM), Norsemont's Qualified Person
under NI 43-101, who has reviewed and approved the content of 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 system for assaying, which
includes the systematic use of standards, blanks, and field duplicate samples.
Secondary laboratories are also used for check assaying. All intersections
were determined using a rolling 0.2% Cu cut-off and up to 5 meters of internal
waste. Due to the disseminated characteristics of the deposit and homogeneity
of the mineralisation, all intersections are to be considered true width.
    Full disclosure of all 43-101 compliant drill results conducted on the
project to date that have or will be used in resource estimations are posted
on the Company's website (www.norsemont.com) under "Constancia Project"
together with a drill hole location map.

    Note 1: Copper equivalent values (CuEQ) are estimated using long-term
    metal prices including: copper US$1.80 per lb, molybdenum US$12.00
    per lb, and silver US$11 per oz. Adjustment factors to account for
    differences in relative metallurgical recoveries for copper, molybdenum
    and silver will depend upon the completion of definitive metallurgical
    testing. CuEQ equals Cu percent plus Mo percent times (8.00/1.20) plus
    Ag grams per tonne times 0.24/(1.20(*)22.05).
    


    The Company also announced that work on the finalisation of the
Constancia scoping study is progressing satisfactorily. The results are
expected to be released in the near future.

    Norsemont Mining is a Canadian mineral exploration and development
company focused on the Constancia copper/molybdenum/silver project in southern
