## Narrative

At approximately 10:22 am the Silver Shaft Hoist began experiencing problems with the release of the brake weights during the weekly hoist and conveyance inspections. The brake weights would not build sufficient air pressure to release once set. Repairs could not be completed within 30 minutes so the mine was evacuated at 10:45 am.
