Bundle Description

Geochemical results of till samples surveyed in the Atholville, Escuminac and Oak Bay regions of New Brunswick are presented. These areas of New Brunswick correspond to NTS map sheet 21 O/15, 22 B/1 and 22 B/2 respectively.

The basal till fractions (< 63 micron) were analysed for As  Sb and Bi using atomic absorption spectrometry (AAS). Hg was analysed using cold vapour atomic absorption spectrometry ( Hg-CVAAS). The samples were analysed for Au using fire assay neutron activation analysis (FA-NA). The analyses were performed by Chemex Labs Ltd. in Mississauga, Ontario.

The analytical data were obtained from Mike Parkhill in 2005 (in an MS Excel spreadsheet).

The geochemical results of this survey were reported by A.G. Pronk and M. A. Parkhill, Geological Survey of Canada.

The data are published in New Brunswick Department of Forests, Mines and Energy Geological Notes Series P.M. 88-10. Some samples from this area were re-analysed and published in New Brunswick Department of Natural Resources and Energy Open File 2002-9.

Analytical Package Description

Laboratory: Chemex Labs Limited

Name: Chemex AAS (As, Sb, Bi) + Hg CV-AAS + FA-NA (Au) (more)

Till samples were dry sieved using an 8 inch sieve shaker.  The <63 µm fraction was analysed for As, Sb and Bi using atomic absorption spectroscopy (AAS).  Mercury analysis was performed by cold vapour atomic absorption spectrometry (Hg-CVAAS).  Au analysis was performed by Fire Assay-Neutron Activation Analysis (FA-NA).  The analyses were performed by Chemex Labs Ltd. in Mississauga, Ontario.
