St. Lawrence Project — 2011 Technical Report
| Company | Canada Fluorspar (NL) Inc. |
| Date | 2011 |
| Commodities | Fluorspar |
| Mine Type | Underground |
Executive Summary
This section of the NI 43-101 Technical Report outlines the recovery methods for the St. Lawrence Project, specifically focusing on pillar extraction strategies within an underground mining environment. RPA estimates that approximately 12% of the pillar tonnage will be extracted during the mine life, involving sill pillars ranging from 5 m to 15 m in thickness. The extraction process utilizes longhole drilling, with loading, blasting, and mucking completed from drawpoints or haulage drifts.
For the BBN mine component, recovery involves drilling uppers and employing electronic blasting techniques to ensure accuracy. While no rib pillar recovery is included in the current production plan, intuitive recovery is expected. A detailed pillar recovery plan could potentially increase tonnage recovery by an additional ten percent, which would extend the mine life by one year.
