SUDBURY, Ontario, April 14, 2026 (GLOBE NEWSWIRE) — Magna Mining Inc. (TSXV: NICU) (OTCQX: MGMNF) (FSE: 8YD) (“Magna” or the “Company”) is pleased to provide the results of ongoing exploration and an update on activities at the past-producing Levack Mine, located in the North Range of the Sudbury Basin, Ontario, Canada (Figure 1). Recent drilling has continued to intersect significant copper-rich massive sulphide veins over approximately 175 metres downhole, within the R2 Footwall Zone. Highlights of hole MLV-26-14A W1 are summarized below and in Table 1. Along with the ongoing exploration at Levack Mine, there are several other activities, including underground development, currently underway in anticipation of a restart decision in the second half of 2026.
Highlights from the new assay results include:
| 23.2% Cu, 5.6% Ni, 21.4 g/t Pt+Pd+Au, 225.0 g/t Ag over 2.4 metres, from 975.9 metres down hole | ||
| And | 10.7% Cu, 1.5% Ni, 14.7 g/t Pt+Pd+Au, 67.1 g/t Ag over 2.1 metres, from 1026.9 metres down hole | |
| Including | 29.6% Cu, 4.0% Ni, 32.4 g/t Pt+Pd+Au, 181.0 g/t Ag over 0.7 metres, from 1028.3 metres down hole | |
| 5.7% Cu, 13.7% Ni, 11.2 g/t Pt+Pd+Au, 28.0 g/t Ag over 0.4 metres, from 1117.7 metres down hole | ||
Dave King, SVP Exploration and Geoscience at Magna, stated, “Hole MLV-26-14A W1 was drilled to test the subvertical veins along the interpreted eastern margin of the R2 Zone, above and east of drillhole MLV-25-14A, which intersected nickel rich mineralization in the upper levels of the R2 Footwall Zone. The new drillhole intersected multiple copper rich veins over approximately 175 metres downhole, and supports Magna’s structural model and interpreted similarities with the controlling structures within the Morrison Footwall Cu-PGE Deposit. Understanding the structural controls is key to efficiently delineating footwall vein deposits in Sudbury’s North Range and identifying areas where more significant mineralization can occur within thicker vein orientations. We will continue to follow-up on defining and expanding the R2 Zone with our surface and underground diamond drills through the remainder of 2026.”
Drilling results reported today are related to Magna’s ongoing exploration program at the Levack Mine, and include new assays from drillhole MLV-26-14A W1, as well as additional assays results from drillhole FNX-6083 W5 received since the initial results were released in February 2026 (see Figure 2 and news release dated February 18, 2026). Complete assay results from these two drillholes are summarized in Table 1. Drillhole MLV-26-14A W1 was designed to better define the eastern margin of the R2 Footwall Zone, along an interpreted north-south mineralized bounding structure. At the Morrison Deposit, located 600 metres to the southwest, more significant massive sulphide veins up several metres thick often occur in the extensional environment between the north-south striking bounding structures that contain narrower mineralized veins (Figure 3). The mineralization in the R2 Footwall Zone may have similar controls, as demonstrated by the multiple veins encountered in drillhole MLV-26-14A W1 with downhole widths ranging from 0.7 – 2.4 metres. Based on our understanding of the Morrison Deposit model, ongoing drilling at Levack will continue to define the mineralized north-south striking structures and explore for potential thicker east-west veins from both surface and underground drilling platforms. A follow up surface drillhole is now underway to test what is interpreted to be the extensional environment at the R2 Footwall Zone approximately 25-30 metres west of the intercepts in drillhole MLV-26-14A W1. In addition, underground drilling to test the R2 Footwall Zone from more optimal orientations has now commenced from the 8451 drill bay on the 1800 Level (Figure 4).
Levack Mine personnel are also re-establishing shaft levels above the 1800 Level and rehabilitating along the 1600 Level and 2650 Level from the No. 2 shaft towards the No. 3 shaft at the eastern extent of the Levack property. These levels will provide additional underground exploration diamond drilling platforms to test areas that are challenging to drill from surface. Once available, a diamond drill will be mobilized to the 2650 Level near the No. 3 shaft to define the upper R2 Footwall Zone and test additional target areas within the footwall of the No. 3 OB.

Levack Mine Progress Update
Highlights of Levack Mine Development Activity Include:
- Development completed for the connection of the 3900 Level ramp to the 3600 Level
- Development underway on the 1800 Level to access the Intermediate Orebody (“IOB”)
- Development planned for an exploration drift from the 2950 Level to provide an additional diamond drilling platform for the R2 Footwall Zone
- Rehabilitation of the 2650 Level to accommodate diamond drilling for the R2 Footwall Zone and below the No. 3 Orebody (No.3 OB) is underway
- Scope of work outlined for the refurbishment of the 2900 Level loading pocket and skipping compartment in the No. 2 shaft
Jeff Huffman, Chief Operating Officer at Magna stated, “Site activity at the Levack Mine has increased significantly over the past six months, with additional personnel and equipment deployed to support project advancement. During this time, notable progress has been made, including the restart of underground mine development as part of preparations for a future return to production. Project and maintenance teams have been actively assessing site infrastructure, defining project scopes, and developing execution plans for 2026. Several of these initiatives are already underway. In the coming months, work will continue to advance exploration efforts, investment of capital in infrastructure and mine development, while progressively improving access to key mining zones.”
At the end of February following 540 feet (165 metres) of underground development at Levack Mine, a breakthrough was blasted to connect the 3900 Level ramp to the 3600 Level drift, which connects the bottom of Levack No. 2 shaft to Vale’s Coleman Mine, located east of Levack (Figure 1 and 3). This connection allows Vale the ability to use the Levack infrastructure as secondary egress for their Coleman Mine. For Magna, the connection re-establishes access to over 4,500 feet (1.4 kilometres) of the Levack property east of the breakthrough on the 3600 Level which will serve as an important platform for future underground exploration.
Following completion of the 3900 Level connection, an additional 360 feet (110 metres) of mine development commenced on the 1800 Level to provide access into the IOB, while progressing a ramp connection to within 688 feet (210 metres) of the 1600 Level (Figure 4). Work on the 1800 Level has also provided access to the 8451 decline which is now serving as an underground drilling platform to define the upper R2 Footwall Zone (Figure 4). Other mineralized zones, including the Main Orebody and the No. 7 Zones are proximal to the 1800 Level and have potential for early mining re-activation.
After the 1800 Level IOB development is complete, mining crews will mobilize to the 2950 Level on the Morrison Ramp and commence development of an 1,140 foot (347 metres) advanced exploration drift towards the R2 Footwall Zone. This development will provide a drilling platform to further evaluate and define the lower portion of the R2 Footwall Zone and other footwall targets between R2 and the Morrison Deposit. Magna has several pieces of mobile mine development equipment already underground in preparation for self-executed mine development in support of exploration and future production.
Results from a major assessment performed by an industry-leading contracting firm on the production hoist plant for the No. 2 shaft have been received and work has commenced on re-commissioning the production hoist. The Levack projects team will prioritize and accelerate work to bring this hoist plant back into service which will support the hoisting of ore and waste upon the anticipated re-start of Levack Mine.
A Preliminary Economic Assessment (“PEA”) based on the recent NI 43-101 Mineral Resource Estimate published on Levack Mine (see news release dated November 18, 2025) is underway with completion targeted for Q3 2026.
