Executive Summary

Date: May 14, 2026
Headline: Tiernan continues work for PFS at Volcan project / Tiernan Advances Multiple Parallel Technical and Environmental Workstreams
Core Announcement: The company has initiated multiple parallel technical and environmental workstreams to advance the Pre-Feasibility Study (PFS) for its Volcan gold project.
Consultants Engaged: Ausenco (Lead PFS), Deswik (Mine Design), SLR Consulting (Resource Estimate), SGS Canada (Metallurgy), GAC (Environmental Permitting).
Progress Milestones: Installation of three meteorological, air quality, and dust monitoring stations completed in February 2026. Core relogging program completed April 29, 2026.
Resource Context: Project holds 9.8 million ounces Measured and Indicated gold resources. Mineralization confirmed to be controlled by veining and alteration intensity rather than lithology.
Management Quote: CEO Fausto Di Trapani describes the workstreams as a "deliberate, coordinated de-risking sequence" purpose-built to support engineering and EIA submission in parallel.

Material Impact

Expectation vs. Reality: The news confirms execution of the strategy announced on February 10, 2026 (C$53M fully funded technical runway). It is consistent with previous projections rather than introducing new surprises.
Materiality Level: Routine - Positive. While positive for project advancement, it does not alter the fundamental investment thesis established in February regarding funding and resource size. The market likely anticipated this progression following the PEA completion and funding announcement.
De-risking Progress: The engagement of major consultants (Ausenco, Deswik) validates the company's claim to be moving toward a bankable study. However, no timeline for PFS completion is provided in this release, leaving uncertainty on when production readiness will be achieved.
Financial Impact: No new capital raise announced; implies existing C$53M runway remains sufficient for current phase. This reduces immediate dilution risk but does not eliminate long-term funding needs for construction.
