Jaguar Mining Inc. ("Jaguar") (JAG-TSX) reports additional significant gold grades and widths from its on-going exploration program at the Turmalina gold project in Minas Gerais, Brazil. This former mine has good infrastructure, a 200 m deep access ramp and 3.9 km of underground development. It is 140 km north-west of the major industrial city of Belo Horizonte, in the Iron Quadrangle greenstone belt.

The assay results are from new holes drilled by Jaguar since December 2004 as part of the current feasibility study program, which should be completed in 2005. Jaguar plans 7,000m of surface diamond drilling at Turmalina and has completed 2,980m in 12 holes. Results from eight of the holes are pending, however, the other four new holes show previously unidentified high-grade gold mineralization that remains open laterally at depth with strong signs of thickening:
