Analytical Sample Bundle Metadata

2002

GSC –NC-2002- Committee Bay 56J, K, O Till: ODM HMC separation, VG grain counts < 2 mm

Type: lab data



Bundle Description

213 till samples from Committee Bay (NTS 56J, K, O) collected in 2001 were processed by Overburden Drilling Management, Ottawa for heavy mineral concentrates and gold grain picking.  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 4277 and Open File 4493 and gold grain data are published in GSC Open File 4277 and Open File 4493.

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 3.2 SG)-0.25-2.00 mm fraction (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 samples are not sieved for 3 size fractions  after being concentrated, rather the 0.25-2.0 mm fraction is sent for indicator mineral processing.
