Jaguar Mining Inc. Increases Turmalina Gold Resources to 730,000 oz

Jun 8, 2006 Download PDF

Jaguar Mining Inc. ("Jaguar") (JAG-TSX) recently completed Phase III of its drilling program at Turmalina and has increased its measured and indicated gold resources from 562,000 oz contained in 2,495,000 tonnes grading 7.0 g/t to 732,848 oz contained in 3,326,363 tonnes grading 6.85 g/t on the extensions of the Main and Northeast Zones. The deepest hole of the Phase III program reached 525 m. The two Zones remain open at depth.

The Phase III results support Jaguar's belief that Turmalina has the potential to grow both reserves and production capacity above current projections. Jaguar has also discovered a parallel structure known as Satinoco, which is located 200 m from the Main Zone. This Zone has been drill tested, confirmed to be mineralized and is projected to add further to the resource base. It is significant to note, when assessing the new resource of 732,848 oz of gold, that 92% of the original measured and indicated resources were converted into reserves. Roscoe Postle Associates Inc. ("RPA") is revising Turmalina's reserves and mine plan based on the foregoing updated resource base. Currently, Turmalina's mineral reserves consist of 370,000 oz of gold contained in 1.9 million tonnes of non-refractory sulfide ore grading 6.0 g/t.

Turmalina's measured and indicated resources after the completion of Phase III are:

The resources 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 provided independent sample preparation and assay services, using standard industry practices. The top cut-off was 50 g/t and the low cut-off was 1 g/t.

Active Growth and Development Program

Jaguar produces gold in the Iron Quadrangle region of Brazil and projects a production profile of over 200,000 ounces per year by 2008. Using its experience and strong local relationships, Jaguar continues to acquire quality gold resources from senior mining companies and is preparing feasibility studies targeting the conversion of the acquired resources to reserves. It controls 72,000 acres of gold concessions, which is the second largest gold property portfolio in the district, and continues to aggressively explore its assets in Brazil's most prolific gold region. Jaguar has 45,833,100 common shares outstanding.
