Jaguar Mining Reports Financial Results for the Fourth Quarter and Full Year 2025

__________________________________________________________________________________________

Toronto, March 31, 2026 – Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG, OTCQX:JAGGF)

today filed its year-end results, the highlights of which are included in this news release. The full set of audited

consolidated financial statements for the fiscal years ended December 31, 202 5 and 2024, accompanying

management's discussion and analysis and annual information form can be accessed by visiting the Company's

website at https://jaguarmining.com or its profile page on SEDAR+ at www.sedarplus.ca. All figures are in US

Dollars, unless otherwise expressed.

Fourth Quarter and Full Year 2025 Highlights

• Fourth quarter results were impacted by the material slump at the Company’s Satinoco dry‑stack facility

within the MTL Complex on December 7, 2024, which led to a temporary suspension of production at the

Turmalina mine. As of the date of this news release, all regulatory restrictions have been lifted, and the

Company has commenced a gradual and controlled restart of operations, in full compliance with applicable

regulatory requirements, while maintaining a strong focus on operational safety and geote chnical stability.

• Gold production for the fourth quarter was 9,356 ounces, with 9,124 ounces sold at cash operating costs¹ of

$1,456 per ounce of gold sold and all-in sustaining costs¹ of $2,268 per ounce of gold sold. Realized gold

prices were $4,170 per ounce in the quarter.

• Gold production for the full year was 40,254 ounces, with 39,453ounces sold at cash operating costs¹ of

$1,277 per ounce of gold sold and all-in sustaining costs¹ of $1,931 per ounce of gold sold. Realized gold

prices were $3,421 per ounce in 2025.

• Revenue for the fourth quarter and full year was $38.0 million and $135.2 million respectively, 10% lower

revenue compared to the fourth quarter of 2024 and 15% lower revenue compared to the full year 2024,

driven by higher realized gold prices year-over-year and partially offset by fewer ounces sold.

• Net loss for the quarter was $20.5 million (loss per share of $0.24). Adjusted net loss1 was $3.3 million or $0.06

per share for Q4 2025, excluding the impact of non-recurring items and the tax implication of said non-recuring

items. The non -recurring items excluded are as follows (i) $15.9 million in expenses recorded due to the

Satinoco pile Incident, (ii) $0.03 million unrealized loss on short-term investment and (iii) $1.4 million of tax

implication of aforementioned expenses.

• Net loss for the full year was $15.8 million (loss per share of $0.20). Adjusted Net Income¹, was $18.5 million

(earnings per share of $0.23) which excludes the following items: (i) $51.2 million in Satinoco-related

expenses, (ii) $2.9 million in recoveries from civil provision reversals; (iii) $9.0 million in gains on short -term

investments; and (iv) $5.0 million in tax recovery related to adjustments.

• Operating costs were $13.3 million in the quarter, a decrease of 25% compared to $17.7 million in Q4 2024.

Lower operating costs in Q4 2025 mainly reflect the ore throughput volume drop resulting from the ongoing

suspension of operations at the Turmalina mine. FY 2025 o perating costs fell 31% to $50.4 million from $73.3

million in FY 2024.

• Unit costs (cash operating costs and AISC per ounce sold) increased year-over-year primarily due to lower

ounces sold and reduced absorption of fixed costs during the suspension period; the Company is

implementing cost-reduction initiatives and expects unit-cost efficiency to improve as volumes normalize.

• Free cash flow1 for the quarter and full year was $0.7 million and $16.6 million respectively and was based on

operating cash flow less asset retirement obligation expenditures and sustaining capital expenditures. Free

cash flow per ounce1 sold for the quarter and full year was $73 and $422 respectively.

• The Company ended the year with $66.5 million in cash and cash equivalents, supporting the restart plan and

near-term operational priorities while preserving financial flexibility.

“Fiscal 2025 was a year that illustrates the resilience exhibited by the teams at Jaguar Mining,” commented

Jaguar Mining CEO Luis Albano Tondo. “While our operational results were impacted by the temporary

suspension at the MTL Complex, our team’s swift and professional response ensured that we met all regulatory

requirements for a safe, controlled restart. Despite these challenges, our cost -reduction initiatives and the robust

gold price environment allowed us to maintain a strong liquidity position, endi ng the year with $66.5 million in

cash. As we move in 2026 with the MTL restrictions now lifted, we are well-positioned to return to our core

objective: growing the Company sustainably through execution of our three-pillar strategy: maximizing our core

assets and Resources, leveraging our exploration portfolio and pursuing M&A opportunities .”

2026 Production Guidance

For the full year 2026, Jaguar Mining projects gold production in the range of 50,000 to 60,000 ounces from

current assets.

Non-GAAP performance measures

The Company has included the following Non-GAAP performance measures in this document: cash operating

costs per ounce of gold sold, all-in sustaining costs per ounce of gold sold, average realized gold price (per ounce

of gold sold), sustaining capital expenditures, non-sustaining capital expenditures, adjusted operating cash flow,

free cash flow, earnings before interest, taxes, depreciation and amortization (EBITDA), adjusted EBITDA and

working capital. These Non-GAAP performance measures do not have any standardized meaning prescribed by

IFRS and, therefore, may not be comparable to similar measures presented by other companies.

The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain

investors use this information to evaluate the Company’s performance. Accordingly, they are intended to provide

additional information and should not be considered in isolation or as a substitute for measures of performance

prepared in accordance with IFRS. More specifically, Management believes that these figures are a useful

indicator to investors and management of a mine’s performance as they provide : (i) a measure of the mine’s cash

margin per ounce, by comparison of the cash operating costs per ounce to the price of gold; (ii) the trend in costs

as the mine matures; and (iii) an internal benchmark of performance to allow for comparison against other mines.

The definitions of these performance measures and reconciliation of the Non-GAAP measures to reported IFRS

measures are outlined below.

gold land position in the Iron Quadrangle with over 42,000 hectares.
