Hemlo Mining Extends B-Zone Mineralization, Uncovers New Geological Unit
Event summary
- Hemlo Mining Corp. discovered a new mineralized volcano-sedimentary unit outside the B-Zone.
- 2025 drilling extended mineralization at depth within the B-Zone by up to 400 metres.
- Mineral resource conversion drilling aims to support a potential increase in Indicated mineral resources 100 metres below current mining areas.
- Hole 90102514 returned 16.1 g/t Au over 3.3 metres, and hole 90102505 returned 14.5 g/t Au over 3.6 metres.
- Hemlo Mining Corp. acquired the Hemlo Gold Mine from Barrick Mining Corp. in December 2025.
The big picture
Hemlo Mining's recent drilling results underscore a broader trend in the gold mining sector: a focus on extending the life of existing mines through aggressive exploration programs. The discovery of the new geological unit, while preliminary, highlights the potential for overlooked mineralization within established mining districts. This strategy allows Hemlo to capitalize on existing infrastructure and reduce capital expenditure compared to developing entirely new mines.
What we're watching
- Resource Conversion
- The success of converting mineral resources to the Indicated category will be a key indicator of Hemlo’s ability to expand its mining operations and justify further investment.
- Geological Risk
- The newly discovered volcano-sedimentary unit presents a greenfield opportunity, but its geological characteristics and potential for significant mineralization remain highly uncertain and require further exploration.
- Operational Efficiency
- Hemlo's ability to leverage existing infrastructure for growth drilling will be crucial for maintaining capital efficiency and delivering on its stated goals of extending mine life.
