Jaguar Mining Provides Gurupi Open Pit Gold Project Update

 

Progressing with Commitments for Equipment Purchase and Financing Negotiations

JAG - TSX/NYSE

CONCORD, NH, Nov. 9, 2011 /CNW/ - Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX: JAG) (NYSE: JAG) is pleased to provide an update for its 100%-owned Gurupi Open Pit Gold Project (the "Project") located in the state of Maranhão, Brazil.

The Board of Directors of the Company has approved continued advancement of the Project.  Construction work on infrastructure is continuing and the development of new housing for relocating families is underway.  The issuance of the Installation License for the construction of the process plant is expected before the end of the year.  The Board of Directors has also approved the ordering of long lead time mining and process plant equipment.  Purchase negotiations are underway.

Daniel Titcomb, Jaguar's President and Chief Executive Officer, stated "We are advancing the base case Project, 5 million tonnes (150,000 ounces) per year.  We are excited about the growth Gurupi will add to the Company.  As our geologists evaluate data from the on-going drilling program and review existing information about surrounding targets, we are gaining confidence that the property has the potential to support a significant production expansion.  We are therefore implementing an aggressive exploration program and associated technical studies to confirm this potential."

Further key activities currently being conducted by the Company are as follows: completion of detailed engineering and the preparation of a definitive control budget; updating of the resource estimates to incorporate ongoing infill and step out drilling results; updating of the Life of Mine (LOM) plan and reserve estimates based on a new resource model and the latest geo-technical design criteria; and preparation of a new cash flow model with updated economic parameters.

Term sheets for non-recourse project specific financing have been tendered from multiple institutions and are currently being considered.  The Board of Directors has approved bringing the Project financing to completion, which is targeted for the first half of 2012.

Exploration Update

The Company has received initial results from the 30,000-meter drilling program at Gurupi.  The results confirm the potential to increase gold indicated mineral resources at the Project's Cipoeiro and Chega Tudo ore bodies, currently estimated at 69,887,500 tonnes at 1.12 grams per tonne totaling 2,518,170 ounces.

"We are very pleased with the results of the first phase of our drilling program at Gurupi," added Titcomb.  "The results suggest down-dip mineralization continuity consistency as expected.  We believe this significantly enhances the Project's exploration potential and the possibility to expand our future production profile in the region."

Previous resource drilling campaigns at the Project had delineated the mineralization down to 170 meters vertical depth at Cipoeiro and 130 meters vertical depth at Chega Tudo.

Phase One of the current program consists of 22,000 meters of infill and step-out drilling intended to convert inferred resources into indicated resources within the pit-shell in accordance with the feasibility study filed on SEDAR in January 2011, as well as test the down-dip continuity of both the Cipoeiro and Chega Tudo ore bodies down to 250 vertical meters on a regular grid.

In addition to the infill and step-out program, a total of eight deeper holes were planned to test the mineralization down to 400 vertical meters.  Preliminary results from deep holes FCTU0023 and KCT420 at Chega Tudo suggest the extension of the mineralization to approximately 300 meters (see Sections A and B below).

While the infill drilling confirms the mineralization is in line with the grade and width indicated from previous drilling programs, the step-out drilling demonstrates that the mineralization is persistent down-dip in both ore bodies as a pervasive pyrite-gold assemblage associated with NW-SE shear zones.

The Company has executed approximately 65 percent (14,346 meters) of the planned Phase One drilling work.  Significant results from the initial 25 diamond drill holes (4,249 meters) that represent the Phase One drilling results available to date at the Cipoeiro and Chega Tudo ore bodies are presented in the tables below.

Phase Two, which is expected to commence in December 2011 and include 53 holes in 8,400 meters, is intended to test the lateral continuation of hydrothermal alteration zones and sulfide mineralization adjacent to Chega Tudo and Cipoeiro in order to potentially expand the existing mineral resource base.

Jaguar expects to provide another exploration update for Gurupi early in 2012.  A new assessment of the Project's mineral resources inventory is expected to be completed during the second quarter 2012.
