Hudbay First Half 2007 Exploration Update

October 15, 2007

-- Aggressive $45 million program continues --

Winnipeg, Manitoba – October 15, 2007 – HudBay Minerals Inc. (TSX: HBM) (HudBay) announces results from its first half 2007 exploration program . Previously released data is available at www.hudbayminerals.com.

During the first half of 2007, approximately 56,430 metres of diamond drilling in 153 surface drill holes was completed. Exploration expenditures including in-mine exploration totaled $20.5 million.

"Exploration is proceeding extremely well," said Peter Jones, President & CEO. "We're taking full advantage to drive organic growth with our $45 million exploration program and surface drilling at 56,430 metres is more than double the same period in 2006."

MINERAL DEPOSIT TARGETS (Flin Flon Greenstone Belt)

Lalor Lake Deposit

The Lalor Lake deposit is approximately 3 km off Highway 395 and 15 km from HudBay's Snow Lake concentrator, which has significant additional capacity.

On August 2, 2007, HudBay provided an update on its ongoing diamond drill program at the Lalor Lake deposit. Mineralization intersections from the first 10 holes at approximately 800 metres from surface indicate a strike length of approximately 550 metres and a width of approximately 700 metres measured in plan view. Based on the 10 holes, the mineralization remains open in at least three directions. The massive sulphide mineralization at the Lalor Lake deposit is coarse-grained and similar to HudBay's nearby Chisel North Mine, and the previously mined Photo Lake and Chisel Mines. These mines had excellent concentrator recoveries and have produced 9.8 million ore tonnes to date, with the Chisel North Mine continuing in production.

The following tabulations are repeated from HudBay's August 2, 2007 news release. Further updates on Lalor Lake are expected to be released prior to October 31, 2007.

Bur Deposit

The Bur deposit is 22 km from the Snow Lake concentrator. Drilling at the Bur deposit in 2007 continued to improve the definition of the known mineralization. During the first half, 5,881 metres were completed in 19 holes. Notable intersections include:

10,539 km of helicopter borne electromagnetic surveys using the Geotech Airborne Survey VTEM system were also completed. These surveys were done to better define targets prior to drill testing and to identify targets in new areas not previously surveyed with the VTEM system.

In conjunction with the Geological Survey of Canada, seismic surveys were in progress in the area of HudBay's Flin Flon and 777 mine properties. These 2D and 3D surveys image stratigraphy at considerable depth.

OPERATING MINES

$2.2 million of underground in-mine exploration was completed in the first half of 2007. Results from this diamond drilling during 2007, will be included in HudBay's mineral reserve and mineral resource estimates for each underground mine as of January 1, 2008.

OPTIONED PROPERTIES (Flin Flon Greenstone Belt)

In the first six months of 2007, HudBay entered into agreements to option exploration land to Rockcliff Resources Inc. and VMS Ventures Inc. In total, HudBay had option agreements in place with six exploration companies at June 30, 2007.

2007 HudBay Procedures

Exploration core drilling was either BQ or NQ size. The core was logged and mineralized intersections were marked for sampling and assaying by geologists and geotechnicians employed by HudBay's subsidiary Hudson Bay Exploration and Development Company Limited (HBED). 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 subsidiary Hudson Bay Mining and Smelting Co., Limited'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, 15 grams was removed for gold determination by fire assaying with Atomic Absorption 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 for check assaying at Acme Analytical Laboratories Ltd. in Vancouver, B.C. This news release provides core lengths and additionally where indicated, horizontal or vertical lengths of mineralization intersected. 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. The data herein and the contents of this news release have been reviewed by Kelly Gilmore, B.Sc. P. Geo., Chief Exploration Geologist with HBED, who is a Qualified Person within the meaning of National Instrument 43-101, with the ability and authority to verify the authenticity and validity of the data.
