TSX - Toronto Stock Exchange · Gold · Arsenic · Antimony · Silver · Canada
TORONTO, ON / ACCESSWIRE / March 29, 2023 / Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG)(OTCQX:JAGGF) is pleased to announce its annual Mineral Reserves and Mineral Resources (MRMR) statement for 2022. The Proven and Probable (2P) Mineral Reserve figures are derived from Jaguar's two operating mines: Turmalina and Pilar. The Mineral Resource figures are derived from these two mines and also includes updated Mineral Resources for the Faina Growth Project following 2022 infill drilling and restated Mineral Resources for the Company's dormant Paciência Complex (CPA). Initial Mineral Resources are also reported from the recent Zona Basal and Pontal South brownfields discoveries.
Detailed tabulations and discussion of this 2022 MRMR disclosure may be found within the Company´s AIF Document which will be uploaded to SEDAR on or before the 31st of March 2023 while an updated NI 43-101 Technical Report for the CPA Complex will be published by the end of May 2023.
HIGHLIGHTS
Proven and Probable Mineral Reservesadditions of 49 koz were offset by mined depletion of 103 koz for a net decrease of 11% to 454 koz, (3816 kt @ 3.70 g/t Au). Measured and Indicated Resourcesincreased by 7% to 1320 koz, (9455 kt @ 4.43 g/t Au). Inferred Mineral Resourcesincreased by 13% to 1191 koz, (10302 kt @ 3.60 g/t Au). FainaGrowth Projectinfill drilling moved the project forward increasing the Measured and Indicated Mineral Resource from 58 koz to 233 koz with conversion from Inferred to Indicated Mineral Resources of 128 koz and with an addition of 47 koz. Paciência Complex (CPA)some 235 koz of Inferred Mineral Resources were added to inventory from Santa Isabel and Margazao after a full review of historical data and for Bahu after 2022 drilling. Life of Mine (LOM)plans at both operations schedules production at current rates into 2027 maintaining a near five-year mineral reserve pipeline in front of operations for the fifth consecutive year. Exploration Resultsfrom in-mine and brownfields areas were robust with solid increases reported in all Mineral Resource categories including initial disclosure of Inferred Mineral Resources reported from two new discoveries (Zona Basal and Pontal South).
Vern Baker, CEO of Jaguar Mining stated, "_Jaguar has generated $91.2M in free cash flow over the last three years and paid out $29.6M in dividends. In addition to making the required investments to sustain current operations, its further objective is to make targeted capital allocations necessary to best exploit the Company's underutilized plant capacity. This year's Mineral Reserve and Mineral Resource update underlines this strategy_."

Mineral Reserves
During the year, at the Company's operations, Proven and Probable (2P) Mineral Reserve additions of 49 koz were offset by mined depletion of 103 koz for a net decrease of 11% to 454 koz (3816 kt @ 3.70 g/t Au).
Turmalina Proven and Probable (2P) Mineral Reserves of 214 koz, (1855 kt @ 3.58 g/t Au) is a net decrease of 42 koz from the prior year. Mining in 2022 depleted 49 koz from the Mineral Reserve offset by a gain of 7 koz.
2P Mineral Reserves at Turmalina can be divided between Orebody A (53 koz, 379 kt @ 4.37 g/t Au), Orebody B (38 koz, 346 kt @ 3.42 g/t Au) and Orebody C (122 koz, 1130 kt @ 3.37 g/t Au).
Pilar Proven and Probable (2P) Mineral Reserves are reported as 240 koz, (1961 kt @ 3.81 g/t Au) which reflects a small net decrease (11 koz) after mined depletion of some 54 koz from the prior year.
2P Mineral Reserves at Pilar can be divided between Orebody BA (29 koz, 223 kt @ 4.1 g/t Au), Orebodies BFs (90 koz, 708 kt @ 3.95 g/t Au), Orebody SW (77 koz, 631 kt @ 3.80 g/t Au), Orebody Torre (21 koz, 178 kt @ 3.73 g/t Au) and others (22 koz, 221 kt @ 3.12 g/t Au).

Quality Control
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.
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.
