Analytical Sample Bundle Metadata


GSC-NC-2002-Timiskaming and Kirkland Lake Area Ontario; Till samples: ODM HMC separation and sorting

Type: lab data

Bundle Description

8 kimberlite boulders collected in 1993 from the Timiskaming and Kirkland Lake area were sent to Overburden Drilling Management, Ottawa, Ontario, 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 boulders were collected in eskers that cross the kimberlite field and were not subjected to crushing prior to processing. No gold was picked from the concentrates.

Grain separation data and indicator mineral are published in GSC Open File 4361.
