GSC-NC-1998- Diamond Lake Kimberlite  Ontario; Till, Glaciofluvial and Kimberlite samples: ODM HMC separation and sorting.

Type: lab data

Bundle Description

2 glaciofluvial and 6 till samples collected in 1979 and 1981 up and down ice of the Diamond Lake kimberlite by the Ontario Geological Survey were sent to Overburden Drilling Management, Ottawa, Ontario picked for gold grains and processed for heavy mineral concentrates (HMC) and sorted. The < 1.7 mm sieved fraction was separated using the table shaker and methylene iodide (S.G.3.3) ; the < 1.7 mm fraction  is separated again  using methylene iodide (S.G. 2.8) to recover the mid-density fraction.

Grain separation data and indicator mineral are published in GSC Open File 3576.

Analytical Package Description

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

Name: ODM Heavy Mineral Separation, VG counts (<1.7 mm fraction-sieving) (more)

ODM heavy mineral separation and visible gold grain counts. Samples are sieved to < 1.7 mm and picked for gold grains. The minerals are separated by methylene iodide with a specific gravity of 3.3. Samples are sieved amd processed for mid density (S.G. 2.8-3.2) fraction.
