TDG Initiates Preliminary Economic Assessment for the Shasta Gold-Silver Project

Executive Summary

• TDG Gold Corp. has initiated a Preliminary Economic Assessment (PEA) for its 100%-owned Shasta Gold-Silver Project in BC, targeting completion in Q3 2026.
• The study will establish the first economic benchmark for the project, evaluating the existing mineral resource alongside a broader scenario that may include the Mets Mining Lease and historical tailings reprocessing.
• Management outlined a near-term strategy focused on value-unlocking through technical studies, a fully funded 2026 Anyox drilling campaign concluding by late June, and a new porphyry-focused exploration program along the Aurora West to Baker Complex corridor.

Key Details

• PEA Scope & Objectives: First economic benchmark for Shasta; evaluates existing mineral resource within a preliminary mine plan and processing flowsheet; leverages Company's infrastructure and current permits.
• Broader Development Scenarios: PEA will assess potential integration of material from the Mets Mining Lease mineralization and reprocessing of historical tailings from the Baker tailing storage facility.
• Consultant & Timeline: Ausenco Engineering Canada ULC appointed as lead consultant; study completion targeted for Q3 2026.
• Expected PEA Outputs: Initial project metrics including potential scale, capital intensity, operating cost profile, mine life, economic sensitivities, and optimization opportunities.
• Corporate Strategy Context: Management cites undervaluation of Toodoggone assets based on 2025 Aurora West drilling success, gold-rich porphyry discovery potential, existing Shasta permits/proximity to Aurora, and high-grade Mets lease characteristics.
• 2026 Exploration Program: Fully funded porphyry-focused program with baseline and targeting studies advancing exploration along the northwest structural corridor from Aurora West to the Baker Complex.
• Anyox Drilling Status: Fully funded 2026 drilling campaign at Anyox expected to conclude by end of June 2026; assay results anticipated thereafter.
• Leadership Change: Steven Kramar departed as Vice President Exploration and Qualified Person after 4.5 years. Paul Geddes, P.Geo. (SVP Business Development & Strategy) assumed interim oversight of technical programs while the Company evaluates candidates for the VP role.
• Technical Validation: Paul Geddes P.Geo. named Qualified Person for the Company's Projects and validated/approved all technical and scientific content in the release.

Notable Quotes

• “A mineral resource is an important foundation, but investors need to understand what that resource may mean economically,” stated Fletcher Morgan, Director and CEO of TDG. “The PEA is designed to provide that first disciplined economic framework for Shasta and to identify the key technical and economic drivers that will guide future work.”
