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

Type: lab data

Bundle Description

73 till and glaciofluvial sand/gravel samples and 2 kimberlite samples collected in 1993 up and down ice of the Diamond Lake kimberlite were sent to Overburden Drilling Management, Ottawa, Ontario picked for gold grains and processed for heavy mineral concentrates (HMC) and sorted. 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). Kimberlite samples were soaked for three days prior to processing.

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