TORONTO, ON / ACCESSWIRE / May 21, 2024 / Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG)(OTCQX:JAGGF) is pleased to provide an update and announce that access development and concomitant mineral resource delineation diamond drilling has intersected high-grade mineralization at its Faina Project ("Faina"). Faina is part of the Company's MTL Mining Complex which also includes its Turmalina Mine, and is located in the state of Minas Gerais, Brazil, approximately 130 kilometers northwest of the city of Belo Horizonte.

In December 2023, the Company released an NI 43-101 Technical Report (see Press Release dated December 18, 2023) announcing Probable Mineral Reserves for Faina of 132 koz (787 kt @ 5.22 g/t Au), Measured and Indicated Mineral Resources of 233 koz (1,427 kt @ 5.08 g/t Au) and Inferred Mineral Resources of 232 koz (1,420 kt @ 5.09 g/t Au).

Since development of the project commenced in 2022, approximately 3,760m of primary access development from the Turmalina Mine to Faina has been achieved, and a further 1,700m of development is planned for 2024, including approximately 560m of secondary productive development. To date, the Company has invested approximately US$15 million in capital at Faina which has mainly been divided between infill resource definition drilling, metallurgical testwork, access development and studies.

Vern Baker, President, and CEO of Jaguar Mining stated: "We are delighted to have reached high grade mineralization in Faina access development and definition diamond drilling. Primary access development and infill diamond drilling will continue to open and better define the mineralized areas through 2024 as the project ramps up to planned production levels in 2025. Our initial plan is to feed mined material through our MTL mill while continuing with focused metallurgical testwork which will inform longer term processing options. Going forward exploration will focus on expanding the Mineral Resources inventory at Faina as well as conversion of Inferred Mineral Resources to higher classification categories."

Faina Mineralization

Gold mineralization is hosted within a series of six separate structurally and stratigraphically controlled mineralized lenses defined as lens E (undifferentiated chemical sediments), and lens F to lens J (meta-mafic rocks). These mineralized lenses occur over several stratigraphic intervals within a mafic volcanic package (amphibolite facies) and are characterized by very fine to fine grained massive to disseminated sulfide rich zones which are both conformable and unconformable with bedding, often accompanied by quartz veinlets and stringers. Sulfides are generally 5-10% of the rock mass within the better mineralized zones with the dominant sulfide minerals being arsenopyrite, pyrrhotite and at times courser grained 1-2cm crosscutting stringers of the antimony bearing minerals stibnite and berthierite are observed. Individual lenses vary in width both along strike and down dip / plunge from less than 1m to greater than 10m with the thicker and higher-grade lenses associated with fold hinges.

Faina Diamond Drilling and Channel Sampling Results

Resource definition diamond drilling successfully intersected the J lens, I lens and H lens as modelled. High grade intercepts with grade x thickness (GT) values greater than 25 (GT) are tabulated below in Table 1. A plan view showing the location of the target lens and diamond drill impact results is presented below in Figure 4.

Faina Lens H Development Channel Sample Results

Positive channel sampling results have been intersected in initial mineralized development on Lens H. The individual sample results and composites are presented in Figure 7 below and tabulated in Appendix 2, Table 4.

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.

About Jaguar Mining Inc.

Jaguar Mining Inc. is a Canadian-listed junior gold mining, development, and exploration company operating in Brazil with three gold mining complexes and a large land package with significant upside exploration potential from mineral claims.
