Magna Mining Announces Q4 Production Results

SUDBURY, Ontario, Jan. 20, 2026 -- Magna Mining Inc. (TSXV: NICU) (OTCQX: MGMNF) (FSE: 8YD) (“Magna” or the

“Company”) is pleased to announce Q4 2025 production results from the McCreedy West Mine, located in the North Range of

the Sudbury Basin, northeastern Ontario, Canada.

Highlights:

• During the quarter, McCreedy West produced 84,953 tons of ore from the 700 Copper Zone at an average grade of

1.31% copper, 0.23% nickel, 1.05 g/t platinum, 1.10 g/t palladium, 0.45 g/t gold and 15.51 g/t silver.

• Underground development during the quarter totaled 1,688 feet, in line with Company forecasts.

• Diamond drilling at McCreedy West during the quarter totaled 29,334 feet, an increase of 91% over Q3 2025.

Jeff Huffman, COO of Magna, stated, “Our team at McCreedy West excelled during the fourth quarter, safely mining and

shipping 84,953 tons of ore to Vale’s Clarabelle mill in Sudbury. Underground mine development continued to be a focus and is

now providing the increased operational flexibility we have been targeting. Magna’s development crews are now fully staffed

and we no longer are using mining contractors for our underground development. The results of a Life of Mine (“LOM”) plan for

McCreedy West, which will include our maiden reserve estimate, is expected to be released in the coming weeks in

conjunction with our 2026 guidance.”

Quarterly production of 84,953 tons of ore represents an increase of 13% over Q3 as mining rates increased in November and

December, following the compressed air system failure and the power related delays, which impacted operations during Q3

and early Q4. Access to stopes with high grade precious metals was achieved during Q4 and resulted in an increase in

platinum, palladium, gold and silver grades compared to Q3. Underground development continued to be a focus during Q4,

totalling 1,688 feet which was in line with expectations. With three underground drill rigs active at McCreedy West for the

entire quarter, diamond drill footage increased to 29,334 feet, up 91% compared to Q3. The increase in diamond drilling will

provide important geological information to support current mining operations, as well as longer term mine planning.

Jason Jessup, CEO of Magna commented, “We ended 2025 on a high note, with very strong fourth quarter production,

combined with excellent development and diamond drilling footage. This has allowed us to remove low grade stopes from our

mining plans and focus on quality production. Although copper is our most important metal at McCreedy West, our grades for

gold, platinum and palladium during Q4 were more than double what we mined in Q3, and silver grades were up more than

40% during a period of strong precious metals prices. This highlights the unique polymetallic nature of Sudbury deposits,

providing us the flexibility to tailor our mining operations to the prevailing commodity price trends. With copper prices near all-

time highs and the recent rebound in nickel prices, McCreedy West has entered 2026 with fantastic operational and economic

momentum. I need to thank the team at the mine for their commitment and dedication to safe production and continuous

improvement at the operation. As we ended 2025, I reflected on what we set out to accomplish at our McCreedy West

operation, which was to invest the capital and effort in the mine to set us up for success in 2026 and beyond. I believe we have

accomplished this goal and 2026 will be an exciting year for Magna.”

by management, are inherently subject to business, market, economic, technical and other risks, uncertainties and

contingencies that may cause actual results, performance or achievements to be materially different from those expressed or

implied by forward-looking statements, including risks and uncertainties relating to the failure of additional drilling to support

assumptions, expectations or estimates of potential mineralization, metal tonnes or grade, the failure of additional drilling to

support additional expansion or delineation of estimated resources, the failure of additional drilling to support production

planning, the failure to maintain an adequate rate of development to maintain production, the failure to meet production, cost or

development expectations, forecasts or guidance, the lack of availability of drill rigs to implement exploration or other programs

or the failure to proceed as quickly as planned with additional exploration or other drilling, continued delays for assay results,

the failure to bring the Levack and Crean Hill mines back into production, and other risks disclosed in the Company’s annual

management discussion and analysis, available on the SEDAR+ website (at: www.sedarplus.ca). Although the Company has
