Jaguar Mining Locates New High-Grade Gold
Mineralization At Turmalina

CONCORD, NEW HAMPSHIRE--(CCNMatthews - Feb. 28, 2005) - Jaguar Mining
Inc. ("Jaguar") (TSX:JAG) 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:
