Vern Baker, President and CEO of Jaguar Mining stated: “The Company faced another difficult quarter as both

mines encountered issues with dynamic orebodies leading to lower grades and tonnes than was expected in the

areas we mined.

At the Pilar Mine, the primary orebodies showed a change in geometry that no longer fit our current mining method

in portions of the orebody. This created both dilution and extraction issues leading to the loss of some planned

mining blocks as well as lower than expected grades in mined blocks. By the end of the second quarter, our planning

team had adapted plans for modifying the mining system to account for the ore being both narrower and flatter than

prior experience.

At the Turmalina Mine, the areas mined in the second quarter showed significantly more variability than was

planned leading to lower than expected grades. The Turmalina grade control program is being modified to improve

stope design and grade control.

After due consideration with internal and external professionals, there is no material change to current Mineral

Resource and Mineral Reserve disclosure.

During the quarter, development continued at the Faina Project with over 300 meters driven. Upgrading of the Faina

Resource from last year´s diamond drilling underpins the project planning. The potential ore zones are expected to

be reached in the fourth quarter and development of the resource into a reserve will begin. In 2024, we plan to

focus on development of ramps, accesses, raises, and other infrastructure to mine effectively in future years.

Given the challenging quarter and the changes we plan to implement to our mining systems during the second half

of the year, we feel it is prudent to temporarily suspend our forward-looking guidance for fiscal 2023 in regard to

the Company’s expected ounces of production and costs so that we can, in the future, provide updated guidance

that should reflect the implementation of the aforesaid changes. We also plan on initiating cost cutting measures to

optimize our cash flow in the second half of the year.”

The Company’s previous guidance can be found on page 4 of its first quarter 2023 MD&A which is available on

Sedar or the Company website.

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.
