HudBay Announces NI 43-101 Mineral Resource Estimate for Lalor
TORONTO, ONTARIO--(Marketwire - Aug. 26, 2008) - HudBay Minerals Inc. (TSX:HBM) is pleased to announce a National Instrument 43-101 (NI 43-101) compliant mineral resource estimate for its 100% owned Lalor Lake (Lalor) deposit in the Flin Flon Greenstone Belt. The Lalor deposit is located near Snow Lake, Manitoba, approximately 3 km from HudBay's Chisel North mine and 15 km from HudBay's Snow Lake concentrator.

CIM Definitions were followed for the estimation of Mineral __ Resources. 2. Mineral Resources are estimated at a zinc equivalency (ZNEQ) __ cut-off of 4% (ZNEQ% equals Zn% + Cu% x 2.352 + Au g/t x 0.626 + __ Ag g/t x 0.009) and a minimum two metre true width. 3. Long term $US metal prices of $700/oz gold, $12.00/oz silver, __ $2.00/lb copper and $0.85/lb zinc were used for the estimation __ of ZNEQ. 4. Metal recovery assumptions of 65% gold, 60% silver, 90% copper __ and 90% zinc were used for the estimation of ZNEQ. 5. Specific gravity measurements using industry standard techniques __ were completed on all assayed intervals.
The mineral resource estimate is effective as of a June 23, 2008 cut-off date, which includes information from 40 drill holes and 5 wedge offsets. Since the cut-off date, HudBay has continued to drill at Lalor with six rigs in an effort to upgrade the Inferred mineral resources and collect samples for metallurgical testing purposes.
Copper and zinc mineralized intersections were geologically interpreted into six stacked lenses, or zones, of zinc rich polymetallic near solid to solid sulphide mineralization at approximately 570 m to 1,170 m below surface.
The reported resource estimates of gold and silver are contained within the interpreted zones of copper and zinc mineralization. However, high grade precious metal intersections also occur outside the mineralized zones and HudBay is currently working with Scott Wilson Roscoe Postle Associates Inc. (Scott Wilson RPA) to evaluate their continuity.
"Our fundamental strategy is to build long-term value organically by leveraging HudBay's assets and our exploration program," said Mr. Palmiere. HudBay has one of the largest and most aggressive exploration programs in Canada. "Lalor continues to be one of our important exploration properties and we look forward to continued assessment of this asset and moving to a Feasibility Study for the deposit."
He added that HudBay is in the process of constructing an all- weather access road to its Lalor site, which is scheduled to be completed by mid September, and preparation of the Feasibility Study is expected to commence during the Company's fourth quarter.
The Lalor core samples were all prepared and analyzed by HudBay's Hudson Bay Mining and Smelting Co., Limited subsidiary (HBMS) at the Flin Flon, MB assay laboratory. As part of HBMS QA/QC measures, pulp duplicates are sent to Acme Analytical Laboratories Ltd. in Vancouver, BC, for comparison and verification purposes.
The mineral resource estimate included in this news release was prepared by Robert Carter, P. Eng., Senior Mines Analyst of HBMS, and audited by Ian Blakley, P. Geo., Senior Consulting Geologist of Scott Wilson RPA. Both are Qualified Persons under NI 43-101 and have reviewed and approved this press release.
A Technical Report supporting the mineral resource estimate in this news release, prepared by Scott Wilson RPA to NI 43-101 standards, will be filed and made available on SEDAR.
