Jaguar Mining Intercepts 13.74 g/t Gold over 9.8 Meters at the Pilar Mine

 

TSX-V: JAG

TORONTO, Aug. 17, 2015 /CNW/ - Jaguar Mining Inc. ("Jaguar" or the "Company") (JAG: TSX-V) today announced the final set of exploration drill results from the 2015 exploration program at the Pilar Mine, located in Minas Gerais, Brazil.  These results include additional high-grade gold intercepts from the latest round of underground exploration drilling.  The most significant high-grade gold results from this drilling campaign come from BFII and BF at the footwall of ore body BA and in particular, drill hole FSB552A with 13.74 grams per tonne Gold ("g/t Au") over 9.8 meters and drill hole PPL 319 with 9.48 g/t Au over 11.15 meters.  (Intersections do not represent true thickness and have been drilled from drill platforms aiming to intersect the mineral resources perpendicular to the plunge and dip of the projected mineralization as possible.)

The Pilar Mine is one of two underground mines that provide ore to the Caeté Mill Complex ("Caeté") and this production currently represents approximately two-thirds of the ounces produced at Caeté.

This 2015 drilling program, initially launched in late Q3 2014, was largely focused to test potential depth extensions of mineralization below level 7 at the Pilar Mine. This program was projected to intersect the mineralization at levels 8, 9 and 10 (figure 1), covering a vertical length of 240 meters (80 meters per level).

The program included 31 diamond drill holes for a total of 6,541 drilled meters. Drill holes were planned along the extensions of existing pay shoots and targeting a grid of 40 x 40 meters. About 80% of drill holes were projected to intercept the mineralization from the hanging wall (average N223 dipping 51o) and 20% to intercept the mineralization from the footwall (average N76 dipping 18o). Average depth per drill hole was 211 meters.

High-grade intercepts reported in Table 1 confirm the depth extensions of the mineralized system at the Pilar Mine. In addition, these results show higher continuity, grade and thickness of the mineralized zones BFII and BF at levels 8, 9 and 10. Ore body BFII shows high-grade results in both the upper and lower limbs while higher grade results are in the lower limb of ore body BF. Ore shoots where the higher grades are concentrated follow the hinge zones of the anticlines.

George Bee, Chief Executive Officer of Jaguar commented: "The Pilar Mine has been subject to a lack of investment in exploration and development as a result of financial constraints. The geology is quite complex and understanding the structural controls is essential. In 2015, we funded a limited program and undertook the exploration in the belief that Pilar and our surrounding claims held potential. These drill results are very exciting and clearly confirm the potential of mineral resources and reserves at the Pilar Mine below level 7, a level currently being mined. These intersections also clarify some geological features and the understanding of mineralization controls that will enable a broader exploration program when further funding becomes available."

Key intercepts includes drill hole FSB552A with 13.74 g/t Au over 9.8 meters, drill hole PPL 319 with 9.48 g/t Au over 11.15 meters, drill hole PPL287 with 5.07 g/t Au over 16.45 meters, drill hole PPL314 with 7.26 g/t Au over 9.25 meters, drill hole PPL316 with 6.59 g/t Au over 10.10 meters, drill hole PPL318 with 8.57 g/t Au over 7.55 meters, drill hole PPL 306 with 9.43 g/t Au over 7.5 meters, including 22.32 g/t Au over 2.70 meters.

Intersections do not represent true thickness and have been drilled from drill platforms aiming to intersect the mineral resource as perpendicular to the plunge and dip of the projected mineralization as possible.

The Pilar Mine is situated in the northeast portion of the Iron Quadrangle about 100 kilometers east of the city of Belo Horizonte in Minas Gerais, Brazil. The deposit is hosted in a metavolcanic sedimentary sequence of the Rio das Velhas Greenstone Belt and the mineralization is located between a folded zone of Banded Iron Formation (BIF) which forms a local isoclinal syncline dipping to SE. The west limb of this syncline has a normal stratigraphic stacking and is called the SW limb and the inverted limb, at the east side, is called limb B. The regional axial plane foliation has general direction of NNE / SSW dipping to SSE.

Mineralized zones are classified according to; the position of the mineralization relative to the major syncline, the morphological continuity and the structural and mineralogical occurrence mode. The mineralization is divided from footwall to hanging wall in SW, LFW, BFII, BF, LHW, BA and C (figure 1).

The SW ore body matches with the west limb, SW, of the syncline.  The LFW ore body consists of a mineralized lens of sericite-chlorite-carbonate-quartz schist present in the footwall of the inverted limb B. The mineralized zones BFII, BF, BH and BA are parasitic anticlines dipping to the SE also in limb B of the major syncline. The C ore body is a group of mineralized lenses of sericite-chlorite-carbonate-quartz schist associated with the contact of the shear zone with the BIF at the hanging wall of limb B.

Quality Control

Jaguar Mining has implemented a quality-control program that includes insertion of blanks, commercial standards and duplicate core samples in order to ensure best practice in sampling and analysis. NQ and BQ size drill core is saw cut and half the drill core is sampled in standard intervals according to geological characteristics such as lithology and hydrothermal alteration contents. The remaining half of the core is stored in a secure location. Rock channel sampling of the underground development follows the same standard intervals of the drill core. The drill core samples are transported in security sealed bags to the in-house Roça Grande Mine Laboratory, Caeté, Minas Gerais and occasionally to the independent SGS Geosol laboratory in Vespasiano, Minas Gerais. The rock chip samples are transported in security sealed bags to the Roça Grande Mine Laboratory, Caeté, Minas Gerais. The preparation and analysis are all conducted at the respective facilities, either at the Roça Grande Mine Laboratory in Caeté, MG or at the SGS Geosol Laboratory in Vespasiano, MG. The Roça Grande Mine Laboratory does not carry an ISO certification. The SGS Geosol Laboratory is ISO 9001 accredited. As part of in-house QA/QC the Roça Grande Mine Laboratory inserts certified gold standards, blanks and pulp duplicate samples.
