Bundle Description

Geochemical results of till samples surveyed in the Alma, Hillsborough, Waterford and Petitcodiac regions of New Brunswick are presented.  These areas of New Brunswick correspond to NTS map sheet 21H/10, 21H/15, 21H/11 and 21H/14 respectively.

The basal till fractions (< 63 micron) were analysed for Ag, As and Sb 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 Al Seaman in 2005 (in an MS Excel spreadsheet).

The geochemical results of this survey were reported in a Master's thesis by Marc Foisy, University of Quebec, Montreal.

The data are published in New Brunswick Department of Natural Resources and Energy Open File Report 89-51 and Plates 90-34A, 90-34B.

Analytical Package Description

Laboratory: Chemex Labs Limited

Name: Chemex AAS (Ag, As, Sb) + 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 Ag, As and Sb 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.
