Analytical Sample Bundle Metadata


GSC-NC-2000-Rankin Inlet 55J, K, N Till: ODM HMC separation, VG grain counts < 2 mm

Type: lab data

Bundle Description

Till samples from Rankin Inlet (NTS 55J, K, N) were processed by Overburden Drilling Management, Ottawa for heavy mineral concentrates and gold grain picking.  50 samples were collected in 1998 and 1999 and processed in 2000.  The < 2 mm fraction was processed for heavy mineral concentrates.  Gold grains were separated and classified according to shape.

Grain separation data are published in GSC Open File 1575 and 3747 and gold grain data are published in GSC Open File 3747.

Analytical Package Description

Laboratory: Overburden Drilling Management, Ottawa, Ontario (ODM)

Name: ODM Heavy Mineral Separation and VG counts (<2 mm fraction table processed) M. I separation 3.3 SG) (more)

Overburden Drilling Management Heavy Mineral Separation process and visible gold grain counts. The < 2 mm fraction from the shaking table is processed. HMC separation follows the standard ODM procedure except that the methylene iodide solution used is 3.3 SG as opposed to 3.2 SG.
