Toronto, Ontario – May 4, 2010 – HudBay Minerals Inc. (“HudBay”, the “company”) (TSX:HBM) net earnings in the first quarter of 2010 were $23.6 million, or $0.15 per share compared with a loss of $4.0 million or $0.03 per share in the first quarter of 2009. Cash provided by operating activities (before changes in working capital) in the first quarter of 2010 was $59.1 million, versus $14.0 million in the same period last year.

Earnings in the first quarter of 2010 were positively impacted by higher metals prices and reduced general and administrative expenses, partially offset by the strong performance of the Canadian dollar, higher depreciation expense and a higher tax rate on earnings. Cash costs per pound of zinc sold, net of by-product credits, were negative US$0.28 per pound, compared to positive US$0.32 per pound in the first quarter of 2009. This decrease in cash costs per pound of zinc sold was primarily due to higher by-product copper credits arising mainly from higher copper prices, offset in part by the stronger Canadian dollar. Overall we remain on track to meet our full year production guidance for 2010.

During the quarter, we repurchased a total of 1,748,100 of our shares at a cost of $23.1 million as part of the normal course issuer bid announced on September 29, 2009.

“The continuing strong performance of our operating assets in northern Manitoba, combined with an improved price environment for all metals, yielded strong results during the first quarter,” said W. Warren Holmes, executive vice chairman and interim chief executive officer. “During the quarter HudBay continued investment at the Lalor project, announced a new improved-grade resource for the Fenix nickel project and continued to prepare the Chisel North mine and Snow Lake concentrator for full production beginning in the second quarter.”

Lalor Project Update

Our Lalor project continues to advance on an expedited basis. The development of the main access ramp encountered minor delays due to water inflows. At the end of the quarter the access ramp had advanced 320 metres. The pilot hole for the production shaft has been completed along with a wedge hole to explore the crusher, load out and other infrastructure zones adjacent to the main shaft area. Drilling results indicate the ground and rock conditions at the proposed site for the shaft are competent and drilling is planned for a pilot hole for the main air exhaust raise. Design of the access road to site has been completed with contractor selection expected in early May and construction work to commence shortly afterwards. We have also received the advanced exploration permits required at Lalor.

Currently six drills are operating at Lalor. One drill is conducting in-fill drilling on the gold zones and two drills are concentrating efforts on the copper-gold zone. Results will be disclosed as they are compiled and evaluated. Other drilling efforts are focused on regional exploration in areas proximate to Lalor, drilling the test pilot hole for an auxiliary ventilation raise at Lalor as described above, drilling short holes characterizing the rock in the immediate vicinity of the Lalor project for civil and geotechnical characteristics and suitability for surface infrastructure, and testing regional exploration anomalies south east of the Snow Lake camp.

Fenix Project Update

On March 31, 2010, we announced a new NI 43-101 compliant mineral resource estimate for our Fenix project in eastern Guatemala. Measured and Indicated resources are 36.19 million tonnes of 1.92% nickel contained in saprolite.

This new resource estimate replaces the previously reported Proven and Probable reserves, as contained in the technical report on Fenix filed in November 2008. We expect this resource will be converted into a reserve with the completion of the updated feasibility study for Fenix scheduled for the third quarter of 2010.

The saprolite resource for the areas outside of the immediate project area, which offer potential exploration upside and opportunity for life of mine expansion, are currently being recalculated and they will also be included with the updated feasibility study.

In parallel with the work that has been ongoing to update the resource estimates:

• We are in the midst of a 7,000 meter diamond drill program at the Fenix project which we expect to complete in the second half of 2010. With four drills operating, the program is concentrated on proposed mining areas 212 and 213, which are located closest to the plant where previous mining by Inco had occurred and where little to no diamond drilling was conducted;

• We have been advancing a revised power strategy for Fenix;

• We have engaged Hatch Engineering and Golder Associates to update the prior feasibility study incorporating the new resource estimate and results are expected in the third quarter of 2010; and

• We are continuing to evaluate financing alternatives for Fenix.

We expect that the various initiatives underway will help us reach a decision on restarting construction on the Fenix project later in 2010.

Production and Sales

Mine production in the first quarter was 520,988 tonnes of ore, compared to 610,395 tonnes for the same quarter in 2009. The lower production was primarily due to the suspension of operations at the Chisel North mine. Copper and silver metal production declined as a result of reduced purchased concentrate volumes.

For the first quarter of 2010, our cash cost per pound of zinc sold was negative US$0.28, a net decrease of US$0.60 from the same period in 2009. The decrease in cost per pound was due primarily to higher by-product copper credits arising from higher prices and volumes, together with reduced general and administrative expense, as 2009 included costs related to the Lundin transaction, shareholder litigation, proxy solicitation and severance.

Operating expenses

For the first quarter of 2010, our operating expenses were $144.8 million, or $9.7 million higher than the same quarter last year. These variances are due to the following:

(in $ millions)	Three Months Ended Mar. 31, 2010
Increased volumes of purchased zinc concentrate	4.4
Decreased volumes of purchased copper concentrate	(21.8	)
Suspension of Chisel North operations	(3.5	)
Changes in domestic inventory	25.8
Higher profit sharing	3.1
Other operating expenses	1.7
Increase in operating expenses in 2010 compared to 2009	9.7

Purchased copper concentrate volumes decreased due to the lack of available concentrate on economic terms. During the first quarter, we sold excess copper inventory that had accumulated in the fourth quarter of 2009, resulting in copper sales which exceeded production and a higher inventory charge in operating expenses compared to the first quarter of 2009.
