Six holes totaling 2,937 m targeted the down-dip projection of the main mineralized trend observed in historical diamond drill holes completed from 2002 to 2005. Three holes targeted the projected trend 100 to 150 m below the current bottom of the optimized pit constraining the 2026 MRE. The remaining holes targeted gaps in the MRE where there was insufficient drill data to estimate gold grades. Drilling has confirmed that the main mineralized trend at UV continues at depth and remains open, with grades and widths consistent with historical drilling and the 2026 MRE. Importantly, multiple new zones of mineralization above the 2026 MRE cut-off grade of 0.19 g/t Au were intersected in areas previously modeled as waste, providing potential to reduce the current 1.8:1 waste-to-ore strip ratio defined within the optimized pit.

Mirado Mine

On June 23, 2026, Kirkland Lake Discoveries Corp. (" KLDC ") announced assay results from its ongoing 2026 diamond drilling program at the past-producing Mirado property. KLDC reported that the broader South Zone mineralization intersected in earlier drilling is interpreted as a major dilation-hosted mineralized area. These holes returned wider zones of mineralization and helped define the main South Zone mineralized body. Drill hole KLM26-011 extended this broader shallow South Zone mineralized area approximately 100 m west of KLM26-004. In the North Zone, KLDC stated that KLM26-008 was drilled approximately 75 m east of KLM26-006 and continues to support KLDC's interpretation of stacked, steeply dipping mineralized structures. When integrated with the South Zone, the expansion in KLM26-011, and the southern high-grade intercepts in KLM26-010, the results support a larger exploration model in which multiple mineralized zones may be connected by a common structural and hydrothermal framework.

On May 25, 2026, KLDC announced assay results from its ongoing 2026 diamond drilling program at the Mirado property. KLDC stated that assay results from drill holes KLM26-005 and KLM26-006, and visuals from KLM26-010 continue to strengthen KLDC's evolving geological model at Mirado and highlight the growing scale of both the South and North Zone systems. KLDC also stated that winter drilling at KL West and KL South came in under budgeted, as a result KLDC has added an additional 5,000 m of drilling at KL South, bringing the total program up to 30,000 m.

Edwards Mine

On June 22, 2026, Alamos Gold Inc. (" Alamos ") reported new results from underground and surface exploration drilling at the Island Gold mine, where exploration drilling has defined high-grade mineralization across multiple areas which are being targeted as sources of additional high-grade mill feed with the expanded Magino mill. Alamos stated that the regional exploration program continues to intersect high-grade gold mineralization at the past-producing Edwards mine located seven kilometers from the Magino Mill. Alamos reported that a total drill program of $43 million has been budgeted for the Island Gold district, part of which will be drilling to be completed at the historic Edwards mine with the objective of extending mineralization beyond historically mined areas.

Metalla holds a 1.25% NSR royalty on the Edwards Mine.
