The drilling results justify further investment in resource definition and development planning.

Proposed Development Scenario: Underground Mining of the Au Panel

Sunshine Metals is evaluating underground development of the Liontown Au Panel as part of the broader Liontown Mining Study. The high grades and geometric characteristics (steeply dipping mineralization) of the Au Panel make underground mining the most appropriate development option. Underground mining economics are favorable when ore grades exceed 5-10g/t gold, and the Au Panel's 7.35g/t average grade exceeds this threshold.

Underground mining development typically requires 24-36 months from project approval to first ore production. The timeline includes detailed engineering design, approvals and permitting, construction of mine access and underground development, processing plant installation, and pre-production commissioning. Sunshine Metals' resource definition work and development planning are critical steps in advancing toward a development decision.

The proposed underground operation would target the 247 kiloton resource at 7.35g/t gold, generating initial ore reserve of approximately 58.2 thousand ounces of gold. This represents a significant development project for Sunshine Metals. Successful underground development would position the company as a gold producer rather than an explorer.
