First Quarter Operating Results

Vern Baker, President and CEO of Jaguar Mining stated: "We are pleased to report that first quarter production improved year over year, however results were once again negatively impacted by a heavy rainy season which created unstable road conditions between the Pilar mine and the Caeté plant. At the Pilar mine, the increase in production was the result of an improvement in head grade. The Turmalina mine was able to drive up production through increased tonnes while experiencing a lower grade cycle within the mine.

Development efforts continue to be focused on our Faina project. An upgrade of a significant portion of the resources to Indicated from Inferred is underpinning our ongoing work on the Faina project. We expect to access the Faina resource zone by year end and see development within the resource next year.

Our guidance for the year is unchanged with gold production expected to be between 84,000 to 88,000 ounces at an All-In-Sustaining-Cost (AISC) range of $1,275 to $1,375 per ounce (US$1:BRL5.20)."

The Iron Quadrangle

The Iron Quadrangle has been an area of mineral exploration dating back to the 16th century. The discovery in 1699-1701 of gold contaminated with iron and platinum-group metals in the southeastern corner of the Iron Quadrangle gave rise to the name of the town Ouro Preto (Black Gold). The Iron Quadrangle contains world-class multi-million-ounce gold deposits such as Morro Velho, Cuiabá, and São Bento. Jaguar holds the third largest gold land position in the Iron Quadrangle with over 50,000 hectares.
