TORONTO, ON / ACCESSWIRE / February 21, 2023 / Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG)(OTCQX:JAGGF) is pleased to announce positive results from recent in-mine diamond drilling at its Pilar mine complex and exploration drilling at its Catita target, located in the Iron Quadrangle in the state of Minas Gerais, Brazil.
In the fourth quarter of 2022, the Company successfully advanced several high priority diamond drill campaigns focused on identifying or extending high grade mineralization at its Pilar mine. This diamond drilling focused on various new targets including holes testing the projected fold hinge within the BA - TORRE structure, the LPA structure, and extensions of a higher grade mineralized trend within the SW structure (press release dated September 13, 2022).
Results from this recent drilling at Pilar has been particularly encouraging with a number of exceptional intersections reporting grade x thickness (GT) intervals greater than 100-gram meters on the BA - Torre and LPA structures on level 16. These intercepts again demonstrate potential down plunge extensions within these structures. The identification of down plunge potential within the BA structure is of particular importance given that this structure was the main historically producing ore zone at Pilar mine at shallower levels. (refer to Table 1 and Figures 1 and 2)
The Company will publish updated Mineral Reserves and Mineral Resources along with its AIF in March 2023.
At Jaguar's Catita Project diamond drilling is targeting potential mineralized extensions to the previously mined Catita open pit. Catita is part of the emerging Córrego Brandão - Catita Mineralized Trend 5km from the Company's CCA plant at Caete. The high-grade intercept reported here provides support for additional exploration focus on this target in 2023.
Vern Baker, President, and CEO of Jaguar Mining stated: "The results reported today include intersections with excellent grade and width, especially in new target areas. This supports our belief that there are still various exciting opportunities that exist throughout the mine. Our geologists continue to refine structural - geological targets that justify ongoing drilling activities. Furthermore, the high-grade intercept reported at Catita demonstrates the clear potential of this target trend which is quickly becoming one of our most prospective target areas within our exploration and growth portfolio".
Pilar Mine Drilling
At Pilar, drilling in the later part of 2022 and into 2023 has been focused on the further delineation and expansion of higher-grade mineralization throughout the mine. Drill testing has generally targeted the projected plunge positions of fold hinges associated with the folded Banded Iron Formations and associated Schists which generally host higher-grade mineralization in previously exploited and or current mining production areas. This tactic is successfully expanding known higher - grade areas and importantly highlighting further potential in new areas. (press release dated September 13, 2022).
Of particular interest is the exceptional intersection in hole PPL850 which reported 42.35 g/t Au (uncut) over an estimated true width of 3.2m within a broader zone grading 20.93 g/t Au over an estimated true width of 10.0m within the BA Structure on 16 level. This intercept opens a new area for exploration close to existing mine development on this level. Figure 3 shows a schematic view aimed at representing the projected BA-Torre Structure fold hinge intersected in hole PPL850 while Figure 4 presents the individual samples contributing to this high-grade intersection.
Similarly hole PPL929 intersected 9.72 g/t Au over an estimated true width of 9.0m within the SW structure again opening the opportunity of adding to the ounce per vertical meter profile on this structure below level 12.
High grade mineralization intercepts with grade x thickness (GT) > 20 (gram per tonne meter) are tabulated below in table 1.

Catita Project Drilling
During 2021 and 2022 Jaguar has been exploring the emerging Córrego Brandão - Catita trend close to its CCA Plant facility near Caete. This trend is defined by an approximately 1.5km northwest - southeast trending structural corridor connecting a major antiformal fold structure centred on the Catita target in the west and a major synformal fold structure centred on the Córrego Brandão target in the east. A strong Au-As in soil anomaly extends along the entire trend.
Exploration in 2021 was largely focused on the Córrego Brandão section of the structure where the initial discovery was made, and which lead to the publication of a maiden Inferred Mineral Resource of some 51koz @ 1.48 g/t Au.
Exploration during 2022 was aimed at expanding exploration along the trend which included commencing a thorough re-evaluation of historical geological and mining data over the Catita target. Geological mapping and resulting structural modelling at Catita is highlighting several priority drill targets within this complex geological setting. Some early success with initial drill testing is being reported here where hole FCAT045 reporting an intersection grading 9.51 g/t Au over a drilled width of 5.9m.

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.

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 third largest gold land position in the Iron Quadrangle with over 50,000 hectares.
