TORONTO, March 25, 2015 /CNW/ - Jaguar Mining Inc. ("Jaguar" or the "Company") (JAG: TSX-V) today reported an independent reserve and resource estimate for its wholly owned Turmalina Mine Complex, supported by a Technical Report compliant with National Instrument 43-101 ("NI 43-101").  The reserve includes a 51% increase in total reserves to 217,000 ounces (1,266,000 tonnes at an average grade of 5.33 grams per tonne).  The 51% increase in reserves from the previous year's estimate of 144,000 ounces (1,471,800 tonnes at an average grade of 3.05 grams per tonne) exceeded the Company's target of replacing reserves mined in 2014.

Reserves at Turmalina, Ore Body A grew by 117% to 180,000 ounces (899,000 tonnes at an average grade of 6.23 grams per tonne) from the previous estimate of 83,000 ounces (463,800 tonnes at an average grade of 5.58 grams per tonne) and significantly, the average reserve grade of the orebody increased by 12% to 6.23 grams per tonne.

The geological drilling database cut-off date used to prepare the estimates is June 30, 2014 and therefore the database excludes drilling results obtained after June 30, 2014, while including depletion from mine activity through December 31, 2014.

George Bee, President and CEO of Jaguar Mining Inc, commented: "As we focus on the Company's turn-around to profitability, we are delighted to see the strength and continuity of higher grades over significant thicknesses of deposition at our Turmalina Orebody A. With the cut-off date for drill results being last June, some 9-months past, the reserve and resource increases announced are just the precursor to reserves that we plan to announce once our 2015, 25,000-m drill program, that tests the continuity of the orebody at depth are announced. He went on to say, "While Orebody A is our clear path to better grade and positive cash flow, the rest of Jaguar's brownfield portfolio, which has been woefully under explored due to prior cash constraints, holds significant potential. We thank the team at RPA for their independent estimate of our reserves and resources, which is aimed at assuring investors of the quality of the assets we hold."

Other
The 2015 exploration work program for Turmalina entails 25,000 metres of drilling targeting the conversion of existing resources to reserves and testing the down-dip extension of Orebody A in an effort to significantly increase resources and life-of-mine.
