ATEX Steps Up Drilling At Chile’s Valeriano Copper-Gold Project
ATEX plans to resume drilling at its Chile-based Valeriano copper-gold project in early October, aiming to complete 28,400 meters of drilling. The results will contribute to a new Mineral Resource Estimate in the second half of 2027, which will provide more details about the project's size and grade. According to the company, closely spaced drilling is necessary to demonstrate consistent mineralization.
