Jaguar Mining Inc. ("Jaguar") (JAG-TSX) reports strong drill results from Phase I of the exploration program of the Satinoco Zone at the Turmalina Mine. Jaguar will proceed with a feasibility study to expand Turmalina's current 587,000 oz reserve base and its 60,000 oz per year gold production rate. Jaguar is targeting a significant increase of reserves and production rate over the next two years. Production at Turmalina is scheduled to begin in Q4 2006.

Main Phase I drill results:

The drill results comprise 7,857 m of drilling from 62 holes. Some of the deeper holes cut the mineralization 220 m below the surface, indicating continuity at depth and consistency with the mineralization of the parallel Turmalina Mine, which has known reserves to 500 m.

The Satinoco Target trend is about 1 km long and is located 250 m from Turmalina's Main Zone. Jaguar intends to access this mineralization through a cross cut underground from the mine.

Phase II of the Satinoco exploration program is underway. Jaguar plans to carry out 12,000 m of additional surface drilling, 1,250 m of drifts and 1,500 m of underground drilling.

The Phase II field work is expected to allow for the completion of the Satinoco feasibility study at an estimated cost of US$ 3.0 million. Historically, the Company has been converting resources into reserves at a cost of $5 to $8 per oz. The feasibility is expected to add reserves up to 500 m deep. The mineralization appears to be open at depth as in Turmalina's Main and NE Zones.

The Phase I exploration results were audited by Ivan C. Machado, M.Sc., P.E., P.Eng., Principal of Salt Lake City based TechnoMine Services LLC. Mr. Machado serves as Jaguar's Qualified Person in accordance with NI 43-101. SGS Laboratories of Belo Horizonte, Minas Gerais are providing independent sample preparation and assay services, using standard industry practices.
