Captivision shares surge 12.49% premarket after positive mining assessment reaffirms gold resources and expands MTMI's potential.

Captivision Inc. surged 12.49% in premarket trading following the release of a positive independent mining assessment by Hard Rock Consulting, which reaffirmed substantial gold and precious metals resources at Montana Tunnels Mining Inc. (MTMI) and highlighted significant potential to expand mining output and extend the mine’s projected life beyond the current 10-year estimate. The report, a key catalyst ahead of the planned acquisition of MTMI, validated the asset’s value and growth potential, reinforcing the company’s strategic pivot to a diversified gold mining business. The acquisition, expected to close in Q1 2026, remains subject to due diligence and Nasdaq compliance, but the positive findings have bolstered investor confidence in the asset’s upside. The stock’s sharp premarket gain reflects optimism about the asset’s long-term viability and the company’s repositioning as a gold mining entity.
