VANCOUVER, Nov 09, 2005 /PRNewswire-FirstCall via COMTEX/ --
Norsemont Mining Inc. ("Norsemont" or "the Company") (TSX-V: NOM; Frankfurt: N8S; WKN: A0DQKK; OTC- BB: NOMFF) is very pleased to announce that assay results for an additional six holes have been received from its Constancia Copper-Gold-Silver-Molybdenum Porphyry Project in southern Peru.
Highlights include: - Hole CO-05-13: 164m of 0.94% Copper (1.13% CuEQ1) - Hole CO-05-14: 301m of 0.77% Copper (0.86% CuEQ1) - Hole CO-05-16: 118m of 0.81% Copper (1.00% CuEQ1) - Hole CO-05-18: 118m of 0.83% Copper (1.00% CuEQ1)
"In addition to exceptional grades, these results include our widest interval of mineralization yet encountered at Constancia." said Marc E. Levy, President and CEO of Norsemont Mining Inc., "Hole CO-05-14 encountered over 300 meters of 0.86% copper equivalent (CuEQ1), including 0.77% Cu, 4.5 g/t Ag, 0.056 g/t Au and 0.002% Mo. We are continuing with our aggressive drill program to infill and expand the limits of known mineralization."

Note 1: Copper equivalent Values (CuEQ) are estimated using long-term
metal prices including: Copper US$1.00 per lb, Molybdenum US$6.00 per lb,
Silver US$6.50 per oz., and Gold US$400 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 (Au grams per tonne
times 12.86/22.05) plus (Mo percent times 132.28/22.05) plus (Ag grams
per tonne times 0.21/22.05).

Recent drilling has encountered blind copper-molybdenum mineralization beneath the skarn and marble on the south end of the Constancia Zone. Drill holes CO-05-12, 14, 16, and 18 encountered excellent secondary chalcocite mineralization, as well as primary chalcopyrite, and occasionally primary bornite in the monzonite directly beneath the cap of skarn. Grades above 1% copper are common in the secondarily-enriched zones directly beneath skarn. More importantly, this Constancia Zone remains open for expansion to the southeast underlying shallow holes completed by previous operators, which were not drilled to sufficient depths to intersect the intensely mineralized skarn/intrusive contact.
Hole C0-05-15 was drilled down or alongside a post-mineral dyke, or possibly a pre-mineral sliver of weakly altered monzonite, with only limited copper mineralization (one 18 meter zone of 0.49% copper and 280 ppm Mo and another 18 meter zone of 0.54% copper and 340 ppm molybdenum). Hole CO-05-17 was drilled in a covered area to the east, but apparently in a lobe of relatively fresh rock between east-west trending extensively mineralized zones.
In addition to ongoing drilling at the Constancia Zone, Norsemont has commenced drilling at the highly prospective San Jose Zone. Drilling will test areas where shallow ( less than 50 meters) drilling by previous operators encountered high grade copper values. The Company will also test prospective leached cap areas in the north San Jose Zone. Assay results on the recently completed holes will be released shortly.
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. 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.
Robert McLeod, P. Geo., Norsemont Consulting Geologist and Qualified Person as defined by NI 43-101 has reviewed and approved information contained in this news release.
A plan map and cross-section with drill hole locations will be available shortly on the Norsemont website at http://www.norsemont.com
Norsemont Mining is a well-structured and financed exploration company working in the America's, with a focus on Peru. The Company is currently drilling the Constancia Cu-Au-Mo project, and commencing exploration at the Amata Ag-Au property acquired from Rio Tinto.
