Mallay Mine Pre-Commissioning Generates Early Concentrate Revenue

The company did not disclose specific revenue figures from pre-commissioning in the announcement.

Three Drill Rigs Targeting Mineralized Zone Expansion at Mallay

The disclosure suggests the company is pursuing resource growth in parallel with the operational ramp-up rather than treating exploration as a secondary priority. No updated resource estimate or drilling results were included in this announcement.
