CONCORD, NH, Dec. 7 /CNW/ - Jaguar Mining Inc. ("Jaguar" or the "Company") (JAG: TSX/NYSE) announced today that it has filed on SEDAR a National Instrument ("NI") 43-101 statement of resources technical report on its newly acquired Gurupi Project in Northern Brazil. The technical report was prepared by Pincock Allen & Holt and states the following mineral resource information for the Gurupi Project:

As previously announced, Jaguar's team is working with AMEC plc on a feasibility study for the Gurupi Project, which is expected to be completed during Q1 2010.

Incorporating the new mineral resources for the Gurupi Project to Jaguar's mineral resource estimates for its properties in Minas Gerais, Brazil, as filed earlier this year, Jaguar's measured and indicated ("M&I") gold resources now total approximately 95,233,340 tonnes at an average grade of 1.97 grams per tonne totalling approximately 6,035,000 ounces. Inferred resources are estimated at approximately 26,072,000 tonnes at an average grade of 2.08 grams per tonne totalling approximately 1,744,000 ounces. The increase in M&I and inferred ounces over the Company's previously filed statement rose 72% and 55%, respectively.

In Q3 2009, the reported run-of-mine (ROM) grades from Jaguar's underground operations averaged 4.37 g/t. Management expects the ROM grades from the ongoing Gurupi feasibility study, which will be an open pit design, are likely to be higher than the resource grades shown herein for the Gurupi Project.

Jaguar's new summary of estimated mineral resources is presented below.
