BRZ

The 40' x 60' service shop building is complete including an automatic door and will serve as the nexus of all plant maintenance and repair.

The company has purchased and received the following additional rolling stock which is now in use: a Caterpillar D-8k dozer with dual rippers for use in the pit, a 5,000-gallon water truck, a Caterpillar road grader, a Caterpillar excavator.

In early December, the cone crusher failed catastrophically after the oil gauge froze and the cone was unwittingly operated without oil. A replacement cone crusher has been purchased and is currently being installed.

The company plans to repair or replace the failed cone as well as repairing or replacing the old jaw crusher and apron feeder so as to avoid similar down-time in the future. In addition, repairs were conducted on our previously unusable Link-Belt crane and are now 90% complete. With this crane in operating condition, we will be able to service and replace large items such as the cone, jaws, and various other key pieces of equipment. Additionally, the crane will allow the placement of several additional filter houses that will aid in the dust control in and around the plant.

Pressurization of the crusher room with outside air has resulted in far less dust entering that room and similar plans to enclose key electrical panels and areas have been made. Replacement of two feed belts in the plant have resulted in more efficient delivery of crushed product.

A road has been completed in the mine pit linking two benches and assisting in the hauling of rock to the plant. Phones at BRZ have been updated using 3 redundant systems and the old, failing, and non-maintained copper line has been abandoned.
