HudBay Updates Drilling at Lalor Deposit: Copper-Gold Zone Remains Open Down Plunge to the North and West

TORONTO, ONTARIO--(Marketwire - Feb. 22, 2010) - HudBay Minerals Inc. ("HudBay", the "company") (TSX:HBM) today announced additional drill results at its 100% owned Lalor deposit near its Snow Lake concentrator in the Flin Flon Greenstone Belt.

Notable results intersected in the previously disclosed Copper-Gold zone include DUB265W01, which assayed 11.70 g/t Au, 30.63 g/t Ag, 6.88% Cu, and 0.37% Zn over 6.44 meters, from 1364.32 to 1370.76 meters, and DUB246W01, which assayed 5.25 g/t Au, 15.26 g/t Ag, 3.58% Cu and 0.15% Zn over 3.35 meters, from 1210.95 to 1214.30 meters. Please refer to the map entitled "Lalor Cu-Au Zone – Plan View February 22, 2010", available on HudBay's web site and at for drill hole intersection locations.

Hole DUB265W01 intersected the mineralization as targeted approximately 150 meters down plunge to the north from the previously disclosed DUB263W02 (the "Discovery Hole") (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). This intersection confirms the Copper-Gold zone remains open down plunge to the north. In addition, a recent Crone Borehole Pulse electromagnetic (BHPEM) survey on hole DUB189 suggests the Copper-Gold zone remains open down plunge to the west. The results of this BHPEM survey are consistent with the results of a recent Geotech Z Axis Tipper Electromagnetic system (ZTEM) helicopter survey of the Lalor area suggesting the areas to the north and west of the Copper-Gold zone are geophysically anomalous.

Drill hole DUB246W01 intersected the mineralization as targeted approximately 90 meters up plunge from the Discovery Hole.

"These results are very encouraging and indicate that the Copper-Gold zone remains open down plunge to the north and west," said W. Warren Holmes, HudBay's executive vice chairman and interim chief executive officer. "Our exploration program will continue this year with additional drilling from surface with the intention of further defining the Copper-Gold zone."

HudBay also has received assays for several drill holes confirming the continuity of the gold mineralization and the presence of high grade lenses in the Gold zone. Notable results include DUB226W06, which assayed 11.07 g/t Au, 21.70 g/t Ag, 0.46% Cu and 0.09% Zn over 24.43 meters, from 877.57 to 902.00 meters and DUB226W07 which assayed 29.65 g/t Au, 42.97 g/t Ag, 0.43% Cu, and 0.05% Zn over 18.38 meters, from 884.22 to 902.60 meters.

"The results to date from in-fill drilling on the Gold zone are better than expected, confirming the continuity of gold mineralization and the potential of high grade gold. Development of the Lalor project continues with significant progress made to date on the ramp access from Chisel North, which will allow for early zinc production and provide an advanced underground exploration platform. We are also drilling a geotechnical pilot hole for a proposed shaft location and continuing work on our pre-feasibility study," added Mr. Holmes.

HudBay continues to explore the Copper-Gold zone with two drills. In addition, one drill continues to confirm the continuity between intersections in the Gold zone, and another drill is testing targets peripheral to the Lalor deposit. HudBay's board of directors has approved total exploration expenditures of $41.7 million in 2010, of which approximately $6.8 million will be dedicated to the Chisel Basin, where the Lalor deposit is located.

The Lalor deposit was discovered in March 2007. The 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 zone: 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. In October 2009 an Indicated Resource of 12.3MT 1.6 g/t Au, 24.2 g/t Ag, 0.66% Cu, 8.70% Zn, and an Inferred Resource of 5.0MT 1.4 g/t Au, 25.5 g/t Ag, 0.57% Cu, 9.39% Zn were disclosed.

Gold zone: Low sulphide precious metal intersections associated with chalcopyrite and galena. In January 2009, HudBay reported the discovery of a new gold zone with the potential to have principal credits derived from gold mining and on October 8, 2009 announced a conceptual estimate of a potential gold zone, interpreted as five discrete mineralized lenses that can contact the near solid sulphide zinc rich mineralization.

Copper-Gold zone: Disseminated to near solid chalcopyrite with lesser pyrrhotite and minor pyrite, sphalerite and galena located to the north of Gold zone 27 at approximately 15 to 20 degrees down plunge and at vertical depths of between 1,200 and 1,300 meters.

For more details on the Lalor deposit, including the resource estimate for the zinc-rich base metals zone and the conceptual estimate of the potential Gold zone, please refer to the NI 43-101 compliant technical report for Lalor dated October 8, 2009 and the company's September 22, 2009, October 8, 2009 and December 17, 2009 news releases, available at

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, exploration and development 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.

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 (HBMS) subsidiary's assay laboratory in Flin Flon, Manitoba where it was dried, crushed and pulverized and a 250-gram sample was prepared for assaying at Acme Analytical Laboratories Ltd., an independent company in Vancouver, B.C., or the HBMS assay laboratory. 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 ICP-AES or gravimetric finish at the Acme laboratory or an Atomic Absorption or gravimetric finish at the HBMS laboratory.

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 was check assayed at a different laboratory, either the HBMS laboratory in Flin Flon or at the Acme laboratory 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.
