CONCORD, NH, Jun 15, 2011, 2011 (Canada NewsWire via COMTEX) --

JAG - TSX/NYSE

Jaguar Mining Inc. ("Jaguar" or the "Company") (JAG: TSX/NYSE) announced today it has received the Preliminary License ("LP") from SEMA, the environmental agency of the state of Maranhão, for its fully-owned Gurupi Project.

The granting of the LP means that the Gurupi Project is environmentally feasible and socially accepted. This includes all infrastructure, processing plant, water usage, tailings impoundment areas and related access and power supply for a five million tonnes per year open pit gold mining operation. The LP is a result of sustained efforts by Jaguar, which involved external consultants, baseline, environmental impact and technical studies, as well as a successful and supportive public hearing conducted by SEMA and involving all stakeholders.

Commenting on this milestone, Mr. Daniel R. Titcomb, Jaguar's President and CEO stated, "The approval of the LP is the cornerstone for Jaguar to reach a decision to proceed, during Q3 2011, with final detailed engineering and advance the project-specific financing process with the Brazilian Development Bank. As with the other four projects Jaguar completed in Minas Gerais over the past six years, our environmental and engineering teams have again demonstrated our ability to permit and develop integrated gold mining and processing operations on-time and on-budget. With the bankable feasibility study we filed earlier this year, we have now achieved the principal components required to finance Gurupi."

Along with cash-on-hand and cash flow from operations, Jaguar expects to raise the balance of the capital necessary to fund the Gurupi Project from the Brazilian Development Bank. The Gurupi Project is slated for commissioning during the first quarter of 2013.

Jaguar has also updated its Corporate Presentation, which can be found on the company's website at www.jaguarmining.com.
