Jaguar Mining Increases Reserves 81%; Large Growing Base of Higher Grade Reserves, Near Surface at Turmalina, To Drive Gold Production Growth and Extend Mine Life

TORONTO, March 1, 2019 /CNW/ - Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX: JAG) is pleased to report Mineral Resources and Mineral Reserves estimates as at December 31, 2018 for its Pilar Gold Mine ("Pilar") and Turmalina Gold Mine ("Turmalina"), each prepared in accordance with CIM definitions (2014) as required by National Instrument 43-101 ("NI 43-101"). Mineral Resources and Mineral Reserves updates are supported by NI 43-101 Technical reports that twill be filed on SEDAR within 45 days.

 Year End 2018 Consolidated Jaguar Mineral Reserves Highlights

  • Consolidated Pilar and Turmalina Mines Proven and Probable (2P) Reserves increased 81% year-over-year (net of 2018 depletion) to 439,000 oz's of gold at a weighted average grade of 4.39 g/t Au (Table 1)

  • Turmalina Proven and Probable tons increased by 74% and grade increased by 12% to 1408 tons at 5.05 g/t containing 228,000 oz´s of gold

  • Pilar Proven and Probable Reserve tons increased by 83% and grade decreased by 8% to 1784 tons at 3.68 g/t containing 211,000 oz´s of gold 

  • Consolidated Proven Reserves increased 123% to 245,000 oz´s of gold at a weighted average grade of 4.01 g/t Au

  • Consolidated Probable Reserves increased 47% to 194,000 oz´s of gold at a weighted average grade of 5.00 g/t Au

  • At both Pilar and Turmalina now have 4 years of Proven and Probable Reserves at current mining rates and over 3 years at target production rates

Ben Guenther, Interim CEO of Jaguar Mining stated: "We achieved solid growth in our 2018 year-end Proven and Probable gold ounces that increased by 81% to a large base of 439,000 ounces compared to 2017, in addition to depletion.  We are especially pleased that results have delivered a meaningful increase in both Proven and Probable tons and grade at Turmalina.  Turmalina Orebody A and Orebody C both have significant life at favorable grades of 5.47 and 4.73 g/t respectively.  Both Turmalina and Pilar have over 4 years of Proven and Probable Reserves at current mining rates and over 3 years at our target production rates. The 2018 focus was on Resource-Reserve Conversion via infill drilling at both operations after significantly increasing our Resource Inventory in 2016-2017 through the growth exploration program."   

"Looking forward, the increase in Mineral Reserves greatly improves our confidence in the production capability to support a return to a growing gold production profile and the potential to extend the mine life at Turmalina and Pilar."

Pilar Gold Mine Mineral Reserves and Resources

  • Infill Drilling and evaluation of remnant material completed in 2018 successfully replaced depletion. Mineral Reserves are now equivalent to more than three years of production at current and planned production rates resulting in total 2P Mineral Reserves of 211,000 ounces of gold (1,784,000 tonnes at an average grade of 3.68 g/t Au) which are 69% higher compared to 2P Reserves of 125,000 ounces as at December 31, 2017.

  • Mineral Reserves at Pilar are based on the main orebodies currently in production centered on Levels 9, 10 and 11 (BA, BF and BFII). Further work is in progress to convert the M&I Resource inventory to 2P Reserves on material from other orebodies and remnant material that are accessible from ramp and access development throughout the mine.

  • The database, used to prepare the estimates, with a cut-off date of December 31, 2018, comprises 1,658 drill holes and 20,698 channel samples. The estimate was generated from a block model constrained by three-dimensional (3D) wireframe models. A capping value varying from 10 to 60 g/t Au was applied for all eight orebodies. Wireframe models of the mineralization and excavated material for Pilar were constructed by Jaguar and reviewed by RPA. A separate wireframe was prepared for each orebody and was used to constrain the grade estimates into the block model.

  • Mineralized material for each orebody was classified into the Measured, Indicated, or Inferred Mineral Resource categories based on the search ellipse ranges obtained from the variography study, the observed continuity of the mineralization, the drill hole and channel sample density, and previous production experience from these orebodies.

  • The Mineral Resources are inclusive of Mineral Reserves. For those portions of the Mineral Resources that comprise the Mineral Reserve, stope design wireframes were used to constrain the Mineral Resource reports. Additional Mineral Resources are present that reside beyond the Mineral Reserves. For these areas, 3D clipping polygons were prepared to aid in the estimation of the Mineral Resources. The clipping polygons were prepared in either plan or longitudinal views, as appropriate. The clipping polygons were drawn to include continuous volumes of blocks whose estimated grades were above the stated cut-off grade, and were not located in mined out areas. The clipping polygons were used to appropriately code the block model and estimate the Mineral Resources.

  • For the December 31, 2018, estimates, the Company prepared an updated geological and block model under the supervision of RPA. The Mineral Resources and Mineral Reserves for 2018 will be supported by a NI 43-101 technical report to be filed on SEDAR within 45 days of this press release.

Turmalina Gold Mine Mineral Reserves and Resources

(Refer to Tables 6-9 below)

  • Proven & Probable Reserves: 1,408 million tonnes grading 5.05 g/t Au, containing 228,000 oz. Au
  • Measured & Indicated Resources: 3,253 million tonnes grading 5.52 g/t Au, containing 577,000 oz. Au
  • Inferred Resources: 1,066 million tonnes grading 4.31 g/t Au containing 148,000 oz. Au

  • Infill Drilling and evaluation of remnant material completed in 2018 successfully replaced depletion. Mineral Reserves are now equivalent to more than three years of production at current and planned production rates resulting in total 2P Mineral Reserves of 228,000 ounces of gold (1,408,000 tonnes at an average grade of 5,05 g/t Au) which are 95% higher compared to 2P Reserves of 117,000 ounces as at December 31, 2017.

  • Orebody C grade and tonnage increases underpinned an 81% increase in shallow – high grade Mineral Reserves to 123,000 oz´s.at 4.73 g/t Au which now surpasses the total Orebody A 2P Mineral Reserve of 105,000 oz´s. (refer to Table 8).

  • Mineral Resource estimates at December 31, 2018, reflect an updated geological and block model prepared by Jaguar staff under the supervision of RPA. This updated block model incorporates the results from the on-going diamond drilling campaigns completed since late 2017.

  • This Mineral Resource includes total Measured and Indicated Resources of 577,000 ounces of gold (3,253 million tonnes at an average grade of 5.52 g/t Au) and Inferred Resources of 148,000 ounces of gold (1,066 million tonnes at an average grade of 4.31 g/t Au).

  • Orebody C Mineral Resource grades have increased following new infill drilling intercepts and from development channel sampling completed in 2018, in particular on Levels 3 and 4. (Please refer to Press Release 27th February 2019).

  • Increases in Measured and Indicated Resources (and concomitant decrease in Inferred Resources) compared to the previously reported resource inventory is in line with the Company's target of replacing reserves mined in 2018 and establishing a significant increase in M&I Mineral Resources mainly below Level 11 on Orebody A and Level 4 on Orebody C (refer to Figures 6, 7, 8 and 9).

  • The database used to prepare the estimates, with a cut-off date of December 31st 2018, comprises 3,980 drill holes and 16,246 channel samples. The estimate was generated from a block model constrained by three-dimensional (3D) wireframe models. A capping value of 50 g/t Au was applied for all three orebodies. The wireframe models of the mineralization and excavated material for Turmalina were constructed by Jaguar and reviewed by RPA. A separate wireframe was built for each orebody and was used to constrain the grade estimates into the block model.

  • The mineralized material for each orebody was classified into the Measured, Indicated, or Inferred Mineral Resource categories based on the search ellipse ranges obtained from the variography study, the observed continuity of the mineralization, the drill hole and channel sample density, and previous production experience from these orebodies.

All sampling and samples utilized at Jaguar for mineral resource and or mineral reserves estimation uses 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. Rock channel sampling of the underground development follows the same standard intervals as for the drill core. All diamond drill hole collars are accurately surveyed using a Total Station instrument, and down-hole deviations are surveyed using non-magnetic equipment (SPT Stockholm Precision Tools with GyroMaster™ Solid State North Seeker).

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 and rock chip samples for resource-reserve conversion and grade control samples are transported for physical preparation and analysis in securely sealed bags to the Jaguar in-house laboratory located at the company´s Caeté Complex, Caeté, Minas Gerais. Growth exploration samples are sent to the independent ALS Brazil (subsidiary of ALS Global) laboratory located in Vespasiano, Minas Gerais, Brazil. The analysis of these exploration samples is conducted at ALS Global's respective facilities (fire assay is conducted by ALS Global in Lima, Peru, and multi-elementary analysis is conducted by ALS Global in Vancouver, Canada). ALS has accreditation in a 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 Mining is the second largest operating gold company tenement holder in the Iron Quadrangle, holding just over 25,000 hectares.
