Examples of Upper Boundary in a sentence
Once the metallurgical parameters were optimized, the five-zone composite and 32 individual samples were used for variability testing.The grinding characteristics of the design mineralized material, an equal mixture of Upper Boundary Zone, Lower Boundary Zone and Pit Zone material as combined material for pilot plant feed gives an average Bond Work Index of 15.6 kilowatt hours per tonne (“kWh/t”) at 100 mesh (106 micrometer (“µm”)) of grind.
In January 2008 Northgate staff prepared an estimate of the Mineral Resources of the Lower Boundary Zone (LBZ), Upper Boundary Zone (UBZ), Lucky Zone (LKY), Lower Lucky Zone (LL1) and the Young-Davidson Zone (YD1-4 Zones) at the Young-Davidson Property (YD Property), Ontario.

The grinding characteristics of the design mineralized material, an equal mixture of Upper Boundary and Pit Zone material as combined gives an average BWI of 18.0. Most samples tested fell in the medium to hard range of hardness with respect to impact breakage and Bond rod mill / ball mill grindability work indices while there was one waste sample which fell in the very hard range of hardness.
In addition to this exploration program, underground delineation drilling in support of future underground mining activities began in late 2010 and is currently focusing on a sector of the Upper Boundary Zone.
The Micon (2004) estimates for the open pit resources and the Young Davidson Upper Boundary Zone (UBZ) underground resources remain the current mineral resource estimates for these areas.

Ground Support Equipment The base station and in-field data processing quality control and quality assurance (QA/QC) system will consist of the following equipment: · A Field Workstation, comprising a Pentium PC, a printer and full data processing software.
The underground mineral reserves have been estimated within a detailed underground mine design based on the use of three bulk mining methods: 1) longhole shrinkage for 8 metre (“m”) to 40m thick ore zones at depth; 2) sublevel cave for the 20m to 40m wide near surface Upper Boundary Zone (“UBZ”) zone; and, 3) sublevel longitudinal retreat for 5m to 10m wide zones.
