TORONTO, Sept. 20, 2017 /PRNewswire/ - Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX: JAG) today announced further positive results from three deep drill holes (1,348 m) as part of its growth exploration program targeting the down-plunge continuity of the principal mineralized Banded Iron Formation Orebodies at Pilar Gold Mine ("Pilar") in Minas Gerais, Brazil (see August 16th, 2017 press release). Drill results include high-grade gold mineralization and in places visible gold, not recently seen, down-plunge from current resources. Importantly, these results validate the projected mineralization plunge and grade of the targeted mineralization well beyond current mine production infrastructure. At the Turmalina Gold Mine ("Turmalina"), three diamond drill rigs are currently focused on growth exploration drilling, targeting projected down-plunge extensions, below current mining levels and infrastructure, on both Orebody A and Orebody C. To date, a total of six holes, totaling over 2,795 m, have been completed with initial results expected to be reported during Q4 2017.

Highlights and Key Intercepts – Pilar

  • Deep drilling continues to intersect high-grade visible gold mineralization, down-plunge of current resources. Key intercepts include 15.9 g/t Au over 11.8 m (ETW 9.6 m), 25.3 g/t Au over 6.0 m (ETW 5.2 m) and 5.3 g/t Au over 49.3 m (ETW 38.7 m) and confirm the thick, high grade intercepts from earlier holes, previously reported in August 2017, which included 10.8 g/t Au over 29.3 m (ETW 22.5 m) in hole PPL449A (refer to Table #1, Figure #1, and Appendix #1 and #2).

  • Drilling results confirm the down-plunge continuity of the principal mineralized Banded Iron Formation Orebodies between Levels 11 to 16, up to approximately 350 m vertically below the current development and 250 m below the current Inferred Resources at Pilar (refer to Figure #1).

  • The presence of visible gold in these thick, higher-grade intercepts confirm drilling is intersecting the major and important controlling fold hinge structures which define the main Orebodies at Pilar.

  • These down-plunge results show increasing thickness of the high-grade Banded Iron Formation mineralization within the principal Orebodies and have the potential to significantly increase our Mineral Resources and expected mine life at Pilar. The mineralization is open for continued expansion down-plunge.

  • A further 3,200 m of diamond drilling has been approved at Pilar aimed at increasing drilling density for inclusion in the updated Mineral Resource and Mineral Reserve estimate expected in early 2018.

Rod Lamond, President and Chief Executive Officer, Jaguar Mining commented: "These additional drill results continue to expand the overall size of the high-grade Banded Iron Formation Orebodies at Pilar and confirm the down-plunge continuity of high-grade mineralized structures well beyond current mine plans. The fact we are intersecting impressive visible gold mineralization with increasing grade and thickness at depth supports our view there is strong potential to add significant new resources and extend mine life at Pilar. Today's results are extremely encouraging and we are becoming increasingly confident in the resource upside of Pilar, which could rival Turmalina, and the mine's ability to have a very positive impact on the Company's future."

"Our commitment to continuing to invest capital in priority growth exploration projects at Pilar is paying off. Operationally, we have made significant strides to increase operating cash flow by reducing and controlling costs. We are realizing tremendous value from redeploying capital made available from these initiatives. We are focused on allocating capital only towards the highest-priority exploration targets across all mine sites that will create long-term sustainable value through increased near-mine Mineral Reserves and Mineral Resources. We are also optimistic that the drill program commenced at Turmalina may deliver similar exploration success when we report drill results before year-end." 

Jon Hill, Jaguar´s Senior Expert Advisor (Geology and Exploration) to the Management Committee commented: "Today's exceptional results, along with those reported last month, confirm the increased tenor of mineralization down-plunge from current production levels. Looking ahead, we are focused on incorporating this mineralization into Pilar's mineral resource model and leveraging the potential benefit of high quality mineralization into the mine plan. These high-grade intersections validate the predictive structural models used to project the plunge persistent mineralization to depth, while also demonstrating the material upside potential of this mineralization to extend even further down-plunge. Growth drilling at Turmalina has commenced smoothly and we look forward to reporting positive results by year-end."

Please refer to Table #1, Figure #1 and Appendix #1 and #2 for more details.

Growth Exploration Program Update – Turmalina

  • Three diamond drill rigs commenced approximately 11,355 m of growth exploration drilling in July 2017 targeting down-plunge extensions to the high grade Orebody A at depth, while also targeting extensions of Orebody C at shallower depths.

  • Approximately 20% of the planned program has been completed to date including a total of six holes,
    five holes for Orebody A and one hole for Orebody C, totaling 2,795 m.

  • Drilling is being undertaken from a hanging wall development drive specifically prepared and completed for this program on Level 10-1. Drilling is intended to reach Levels 12 to 16, up to 420 m vertically below the current development and 300 m below the current Inferred Resources (refer to Figure #2).
     
  • At shallower levels, drilling will target projected down-plunge extensions to Orebody C which, once confirmed, will allow access for mining from existing infrastructure between Levels 4 and 10 (see Figure #3).

  • Regular updates on progress with results are expected to be released over the coming months prior to reporting updated Mineral Reserves and Mineral Resources in March 2018.

Qualified Person

Scientific and technical information contained in this press release has been reviewed and approved by Jonathan Victor Hill, BSc (Hons) (Economic Geology - UCT), Senior Expert Advisor Geology and Exploration to the Jaguar Mining Management Committee, who is also an employee of Jaguar Mining Inc., and is a "qualified person" as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101").

Quality Control

Jaguar continues to use a quality-control program that includes insertion of blanks and commercial standards in order to ensure best practice in sampling and analysis.

HQ, NQ, and BQ size drill core is sawn in half with a diamond saw. Samples are selected for analysis in standard intervals according to geological characteristics such as lithology and hydrothermal alteration contents. All diamond drill hole collars are accurately surveyed using a Total Stations instrument and down-hole deviations are surveyed using non-magnetic equipment with Icefield Tools' Gyro Path® NSG equipment and SPT Stockholm Precision Tools with GyroMaster™ Solid State [North Seeker].

Mean grades are calculated using a variable lower grade cut-off (generally 0.5 g/t Au). No upper gold grade cut has been applied to the data. However, the requirement for assay top cutting will be assessed during future resource work.

Half of the sawed sample is forwarded to the analytical laboratory for analysis while the remaining half of the core is stored in a secure location. The drill core samples are transported in securely sealed bags and sent for physical preparation to the independent ALS Brasil (subsidiary of ALS Global) laboratory located in Vespasiano, Minas Gerais, Brazil. The analysis is conducted at ALS Global's respective facilities (fire assay are conducted by ALS Global in Lima, Peru and multi-elementary analysis are conducted by ALS Global in Vancouver, Canada). ALS has accreditation in global management system that meets all requirements of international standards ISO/IEC 17025:2005 and ISO 9001:2015. All major ALS geochemistry analytical laboratories are accredited to ISO/IEC 17025:2005 for specific analytical procedures.

The Iron Quadrangle

The Iron Quadrangle has been an area of mineral exploration dating back to the 16th century. The discovery in 1699-1701 of gold contaminated with iron and platinum-group metals in the southeastern corner of the Iron Quadrangle gave rise to the name of the town Ouro Preto (Black Gold). The Iron Quadrangle contains world-class multi-million ounce gold deposits such as Morro Velho, Cuiabá, and São Bento. Jaguar holds the second largest gold land position in the Iron Quadrangle with just over 25,000 hectares.
