HudBay Announces Major New Copper-Gold Intersections at Lalor

HudBay intersects 34.5 meters of 13.35 g/t Au and 5.33% Cu

TORONTO, ONTARIO--(Marketwire - Sept. 22, 2009) - HudBay Minerals Inc. ("HudBay", "the company") (TSX:HBM) today announced major new copper and gold drill hole intersections at its 100% owned Lalor deposit near its Snow Lake concentrator in the Flin Flon Greenstone Belt.

Recent drill holes intersected what is believed to be a new zone of significant copper-gold rich mineralization that is lower in the stratigraphy than the previously announced zinc rich Base Metal zone and Separate and Contact Gold zones. At Lalor, HudBay has now identified a zinc rich Base Metal zone, as described in a NI 43-101 technical report dated September 19, 2008, Separate and Contact Gold zones, and most recently a new Copper-Gold zone.

Recently, drill hole DUB263W02 intersected the new Copper-Gold zone, and assayed 13.35 g/t Au, 27.98 g/t Ag, 5.33% Cu and 0.35% Zn over 34.54 meters from 1253.08 to 1287.62 meters. (Please see attached table).

Notable results were also intersected in drill hole DUB252W01, which are believed to correlate with the new Copper-Gold zone and which assayed 12.54 g/t Au, 26.67 g/t Ag, 3.69% Cu, and 0.18% Zn over 9.12 meters from 1140.00 to 1149.12 meters and 8.08 g/t Au, 15.33 g/t Ag, 1.60 % Cu, and 0.12% Zn over 13.39 meters from 1176.00 to 1189.39 meters.

"The copper and gold intersection in hole DUB263W02 is among the best I have seen in nearly 40 years in the mining business and the new Copper-Gold zone may be very significant," said Peter R. Jones, HudBay's chief executive officer. "Excluding the new Copper-Gold zone, HudBay's target is to reach three million contained ounces of gold. The Lalor project is our focus and we will continue to advance it to a production decision with the highest priority."

HudBay also announced today that by early October 2009 it expects to release the following for the Lalor project:

- An updated NI 43-101 compliant resource estimate for the zinc rich Base Metal zone for use in the Lalor feasibility study;

- A new NI 43-101 compliant conceptual estimate of potential tonnes and grade for the Separate and Contact Gold zones;

- Additional drill hole assay information concerning the Separate and Contact Gold zones;

- The access method to the Lalor deposit, either by dual shafts, or a single shaft and ramp from HudBay's Chisel North mine, which is three kilometers from the deposit; and

- Conceptual project design parameters, including construction and production timelines, and capital costs.

"Since 2007, and especially this past year, considerable effort has been invested to advance the Lalor project. We have committed to high standards of transparency to our investors and are pleased to now be sharing these extraordinary results and our plans with them," said Mr. Jones. "In addition, we expect to immediately commit to a pre-feasibility study and consideration of an early access to the deposit."

HudBay announced the Lalor discovery in March 2007 and subsequently announced an Indicated Resource of 3.4MT 1.9 g/t Au, 20.5 g/t Ag, 0.71% Cu, 8.82% Zn, and an Inferred Resource of 13.2MT 2.9 g/t Au, 34.1 g/t Ag, 0.70% Cu, 8.19% Zn (for further details please see HudBay's NI 43-101 technical report dated September 19, 2008). In January 2009, HudBay reported the discovery of a new gold zone with the potential to have principal credits derived from gold mining.

Since the last press release on Lalor dated May 5, 2009, the ongoing exploration program at Lalor has focused on extension of the Separate and Contact Gold zones as well as improving the knowledge of their continuity.

Five drills continue to operate at Lalor, with two exploring the extensions to the Separate and Contact Gold zones and the newly discovered Copper-Gold zone. Two other drills are focused on close spaced drilling within the Separate and Contact Gold zones to further confirm gold mineralization continuity and one drill is collecting metallurgical samples.

ABOUT LALOR

The Lalor deposit is located in the Chisel basin portion of the Flin Flon Greenstone Belt and is believed to be the largest VMS deposit found in this region to date.

- Zinc rich base metal mineralization occurs in six separate stacked lenses of zinc rich polymetallic near solid to solid sulphide mineralization approximately 570 meters to 1,170 meters below surface.

- Contact Gold zone: Low sulphide precious metal intersections associated with chalcopyrite and galena occur in zones in contact with the near solid sulphide mineralization. These intersections are generally high in gold and silver and are located in the immediate hanging wall or footwall or displaced several meters away from the near solid sulphide zinc rich mineralization.

- Separate Gold zone: Low sulphide precious metal intersections associated with minor chalcopyrite and minor galena. These intersections are generally significantly removed from the near solid sulphide lenses and do not appear to have any association with them; however they merge, overlap and cut through them, particularly with Zone 20.

- Copper-Gold zone: Disseminated to near solid chalcopyrite with lesser pyrrhotite and minor pyrite, sphalerite and galena located approximately 100 meters below the Separate Gold zones.

For more details please refer to the NI 43-101 compliant technical report for Lalor dated September 19, 2008 and the May 5, 2009 press release entitled "HudBay's Lalor exploration yields more precious metals intersections."

The Lalor deposit is approximately 15 kilometers from HudBay's concentrator in Snow Lake, Manitoba, an area that is a significant past producer of gold. The ongoing evaluation and exploration of the Lalor deposit is a primary focus for the company, as the Lalor deposit could be of significant financial benefit to HudBay and support substantial long term activity in the Snow Lake area.

QUALITY ASSURANCE AND QUALITY CONTROL

Exploration core drilling was NQ size. The core was logged and mineralized intersections were marked for sampling and assaying by geologists and geotechnicians employed by HudBay's Hudson Bay Exploration and Development Company Limited (HBED) subsidiary. The marked intersections or intervals were sawn in half by a diamond saw and one half of the core was placed in plastic bags and tagged with unique sample numbers, while the second half was returned to the core box and stored. Each bagged core sample was transported to HudBay's Hudson Bay Mining and Smelting Co., Limited subsidiary's assay laboratory in Flin Flon, Manitoba where it was dried, crushed and pulverized and a 250-gram sample was prepared for assaying. From each 250 gram sample 0.25 grams was removed and leached in aqua regia and analyzed by ICP-AES for Ag, Cu, Zn, As, Pb, Ni and Fe. Also from the 250-gram sample, 30 grams was removed for gold determination by fire assaying with an Atomic Absorption or gravimetric finish.

Assaying integrity is monitored internally with a quality control program, which includes the use of assay sample standards, blanks, duplicates and repeats and externally through national and international programs. In addition, within each group of 20 core samples, one core sample has a second 250 gram split collected that will be check assayed at Acme Analytical Laboratories Ltd., an independent company in Vancouver, B.C. This news release provides core lengths and estimates of vertical thickness only. True widths are not provided. Where metal assays are provided for intersections they are either a single assay of a sample of the entire intersection length or a composite of assays calculated from interval weighted assays over the intersection length.
