PR Newswire (Canada)
VANCOUVER, Nov. 10 /CNW/ -- VANCOUVER, Nov. 10 /CNW/ - Northgate
Minerals Corporation (TSX: NGX, NYSE Amex: NXG) is pleased to
report positive exploration results from diamond drill programs at
its Fosterville and Stawell Gold mines in Victoria, Australia.
Exploration Highlights -- Fosterville: drilling below and
down-plunge of the Phoenix Reserve block continues to show
promising results:
Phoenix
Footwall -- Drilling within the Footwall has intersected strong
mineralization: hole UDE038 (6850 mN) intersected 5.4 grams per
tonne ("g/t") gold over 24.9 metres ("m"), including 11.5 g/t over
5.6 m and 10.1 g/t over 4.3 m. -- Hole UD756 (7360 mN) intersected
4.7 g/t over 6.3 m and 5.5 g/t over 18.6 m, including 8.1 g/t over
9.1 m. -- These holes follow on assay results released previously:
hole SPD547B (7000 mN) returned 6.3 g/t over 23.3 m and 4.6 g/t
over 6.5 m. -- Results from the Footwall indicate that there is
potential to add new reserves close to the existing Phoenix
underground development and to increase ounces per vertical metre
immediately below the existing reserves.
Phoenix
Extension (6850 mN) -- Hole UDE037 intersected 14.1 g/t over 4.7 m
and hole UDE038 intersected 5.8 g/t over 5.0 m. -- These holes
follow on the assay results released previously: hole SPD527C (6950
mN) returned 6.5 g/t over 5.1 m and hole SPD526C (6900 mN) returned
12.2 g/t over 6.3 m. -- Results indicate the potential for
increasing the Phoenix Extension zone another 150 m south along
strike and down plunge. -- Stawell: in addition to the two new gold
discoveries in previously untested areas (see press releases dated
August 31 and November 1, 2010), drilling from Golden Gift 6 Lower
("GG6L") intersected high-grade mineralization, further enhancing
the new GG6 reserve zone, with current average reserve grade of 6.3
g/t:
Basalt
Contact: -- Hole MD-5338 returned 13.2 g/t over 4 m. -- Hole
MD-5281 contained several excellent intervals: 4.9 g/t over 16.4 m,
including 7.1 g/t over 7.6 m and 15.9 g/t over 5.1 m. -- Hole
MD-5790 also contained several excellent intervals: 5.7 g/t over
5.2 m, including 13.0 g/t over 1.5 m; a second interval returned
5.8 g/t over 9.7 m, including 8.0 g/t over 3.0 m and 13.2 g/t over
1.5 m.
Waterloo:
-- Hole MD-5281 returned 24.0 g/t over 10.6 m. -- Hole MD-5481
returned 21.0 g/t gold over 3.1 m. Ken Stowe, President and Chief
Executive Officer, remarked, "The excellent results received to
date represent a significant step towards achieving our goal of
reserve and resource expansion at our Australian mines.
Drilling within the Phoenix Footwall and Extension down dip from
the existing reserves is testing for the large scale continuity of
the Phoenix Deposit, which has been the most productive orebody
identified on the property to date, and while in its early stages,
we are encouraged by the excellent results and the potential to add
to reserves. We also continue to be very excited on the
progress that is being made at Stawell in identifying new areas on
our mining lease, including two new gold bearing basalt domes and a
potentially significant waterloo zone, as we look to make further
extensions to the mine life." 2010 Diamond Drill Programs
Fosterville - Phoenix Footwall and Phoenix Extension To date, three
holes have been drilled totalling 1,590 m using underground
drill platforms. We are encouraged by results within the
Phoenix Footwall, which has appreciable widths and grades and has
the potential to be an ore shoot paralleling the known Phoenix
orebody. A drill program is in progress in the area between 7200 mN
and 7500 mN to determine the grade and continuity of this potential
zone. Drill results from the Phoenix Extension indicate the
potential for extending the Phoenix orebody another 150 m south
along strike and down plunge. A drill program is also progressing
on section 6850 mN to potentially extend mineralization up dip of
existing drill intersections. Figure 1: Fosterville Gold Mine Long

Stawell - GG6L Drilling within GG6L is ongoing, where there is
potential to add to high-grade reserves similar to the 6.3 g/t
reserve grade within GG6. Assay results received to date are
presented in the following tables and have returned significant
thicknesses of mineralization. The GG6L mineralized zone extends
over 200 m along strike and over 180 m in vertical height
at present. Since 2008, a total of 13 holes have been drilled into
the GG6L scoping program. Seven of these holes intersected the
high-grade basalt contact zone. While the initial work in the GG6L
zone has centered on the high grade basalt contact mineralization,
the discovery of a potentially significant waterloo zone further
east of the main basalt contact provides another high-grade area to
focus on. Potential for further upside at GG6L is promising.
Multiple ore surfaces in the GG6L zone and extensions at depth, as
well as the identification of the waterloo zone, all present
excellent opportunities for additional ounces to be discovered in
the GG6L zone. The exploration team at Stawell has begun the
interpretation of the drill intercepts for a GG6L resource
estimate. Upon completion of the proposed 2011 drill program, it is
expected that there will be 27 intercepts into the basalt contact
zone at 50 m by 50 m spacing, which should be sufficient
to initiate resource definition drilling in the zone with the focus
on reserve conversion. Figure 2: Stawell Gold Mine Long Projection

Regarding Mineral Reporting Standards: Northgate prepares its
disclosure in accordance with the requirements of securities laws
in effect in Canada, which differ from the requirements of U.S.
securities laws. Terms relating to mineral resources in this press
release are defined in accordance with National Instrument
43-101-Standards of Disclosure for Mineral Projects under the
guidelines set out in the Canadian Institute of Mining, Metallurgy,
and Petroleum Standards on Mineral Resources and Mineral Reserves.
The Securities and Exchange Commission (the "SEC") permits mining
companies, in their filings with the SEC, to disclose only those
mineral deposits that a company can economically and legally
extract or produce. The Company uses certain terms, such as,
"measured mineral resources" "indicated mineral resources",
"inferred mineral resources" and "probable mineral reserves", that
the SEC does not recognize (these terms may be used in this press
release and are included in the Company's public filings which have
been filed with securities commissions or similar authorities in
Canada). pbMs. Keren R. Yun,/bDirector, Investor Relations, Tel:
