The Underground Tunnel Breakthrough | James Anderson - Guanajuato Silver
The Deep Dive Jun 30, 2026
Summary
A tunnel linking the San Ignacio and Bolognese sides should connect within weeks, cutting ore haul distance by a couple of kilometers.
Shorter haulage lowers transportation costs and lets the mine's underground fleet move material far more easily.
The connection opens existing ventilation shafts on the Bolognese side, improving airflow across the whole operation.
Key points on Guanajuato Silver
- As of June 2026, the speaker expects active tunneling from both sides to link up within weeks, which he says will immediately reduce transportation costs from San Ignacio to the plant.
- The connection puts the operation a couple of kilometers closer to the plant, making it easier for the underground fleet to move material.
- Linking the sides also opens existing ventilation shafts on the Bolognese side that the San Ignacio side lacks, improving ventilation across the whole operation.
James Anderson's takeaways
- Top takeaway As of June 2026, the speaker argues the two tunnel headings will connect within weeks, shortening the haul from San Ignacio to the plant by a couple of kilometers.
- He frames the link-up as also improving ventilation by opening existing shafts on the Bolognese side, benefiting the whole operation.
