Confirms strong metallurgical potential and local processing capability, building on previously announced 95% silver recovery

EraNova Metals Inc. (TSX-V: NOVA) (OTCQB: STXPF) announces the successful production of a 50 oz refined silver bar from the remaining tailings generated during metallurgical testing of the Company’s previously announced 1,585 lb (719 kg) surface mini-bulk sample (Press release dated December 1, 2025) collected from the Silver Surprise zone at its 100%-owned Ruby Creek Property near Atlin, British Columbia.

Highlights

• 50 oz refined silver bar recovered from remaining mini-bulk sample material at Silver Surprise.
• Builds upon the previously announced 95% silver recovery achieved through direct smelting.
• Demonstrates the continued metallurgical potential of the Silver Surprise mineralization.
• Silver processed locally in Atlin, BC, demonstrating access to metallurgical expertise that supports efficient advancement of future exploration programs.

“Producing a 50 oz refined silver bar is an exciting milestone for EraNova because it highlights just one of several value drivers we’re advancing simultaneously,” said Meredith Eades, President and CEO of EraNova. “While the Adanac Molybdenum Project advances toward a Preliminary Economic Assessment, we’re also continuing to demonstrate the broader discovery potential of the Ruby Creek district. Advancing both a development-stage asset and a pipeline of exploration targets simultaneously reflects the unique opportunity we see within EraNova. The ability to process material locally in Atlin further demonstrates the existing infrastructure and accessibility surrounding the project. Taken together, we believe these advantages underscore the value within EraNova and the long-term opportunity for our shareholders.”

Local Processing Supports Future Exploration

The silver bar was produced by Rino Mihoc of Ruby Gold Ltd. at his processing facility in Atlin, British Columbia, located approximately 20 kilometres from the Ruby Creek Property. The bar was poured from the remaining tailings generated during the Company’s previously announced metallurgical program, which demonstrated 95% silver recovery through direct smelting.

The availability of local processing infrastructure allowed the Company to further evaluate the original mini-bulk sample without transporting material over long distances. As EraNova continues to advance exploration across the Ruby Creek district, access to nearby metallurgical expertise can provide an efficient means of evaluating future bulk samples and supporting ongoing exploration programs.

Building on Strong Metallurgical Results

As announced on December 1, 2025, metallurgical testing of the Silver Surprise mini-bulk sample demonstrated:

• 95% silver recovery through direct smelting;
• Recovery of native silver using simple gravity concentration techniques;
• Production of an initial 445 g (14.3 oz) refined silver bar from gravity concentrate; and
• Metallurgical characteristics consistent with simple processing of coarse native silver mineralization.

The production of the 50 oz silver bar further validates the high-grade nature of the Silver Surprise mineralization while complementing the strong metallurgical results previously reported from the mini-bulk sample. The Company continues to evaluate opportunities to further optimize the gravity concentration process as part of its ongoing metallurgical assessment.

Silver Surprise Zone

The Silver Surprise Zone hosts the highest-grade silver mineralization identified to date on the Ruby Creek Property. Previous surface sampling returned assays of up to 16,030 g/t silver, including 28 samples exceeding 1,000 g/t silver and four samples exceeding 10,000 g/t silver. Mineralization occurs within multiple sub-parallel quartz-sulphide veins that remain open along strike and at depth.

Silver Surprise remains one of several high-priority exploration targets within the broader Ruby Creek district. While the Company advances the Adanac Molybdenum Project toward a NI 43-101 compliant Preliminary Economic Assessment, exploration is currently in progress, advancing high-grade precious and base metal targets across the property.
