GSC-NC-1996- B30 Kimberlite Ontario; Till and Kimberlite samples: ODM HMC separation and sorting and Indicator Mineral Picking

Type: lab data

Bundle Description

76 till samples collected in 1995 up and down ice of the B30 kimberlite and 4 kimberlite samples were sent to Overburden Drilling Management, Ottawa, Ontario, picked for gold grains and processed for heavy mineral concentrates (HMC) and sorted. Kimberlite samples were soaked for 3 days prior to processing. The < 1 mm sieved fraction was separated using the table shaker and methylene iodide (S.G.3.2) ; the 1-2 mm fraction is separated only using methylene iodide (S.G. 3.2).Till and kimberlite concentrates are sieved then till samples were picked for 18 indicator minerals including Cr-pyrope, Mg-ilmenite and chromite.

Grain separation data and indicator mineral are published in GSC Open File 3295.

Analytical Package Description

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

Name: ODM Heavy Mineral Separation, VG counts (<1 mm fraction table processed) and HMC Indicator mineral picking (more)

Overburden Drilling Management indicator mineral processing (till and kimberlite samples).  Kimberlites are soaked for three days prior to sorting and sieving.  The grain separation procedure corresponds to the standard ODM flow chart.  Concentrates are picked for 18 indicator minerals including Cr-pyrope, Mg-ilmenite and chromite.
