NTS 093J (McLeod Lake) INAA Geochemical Reanalysis
- W. Jackaman, Noble Exploration Services Ltd.
The McLeod Lake map area (just north of
Prince George) has the potential to host
many different types of economic mineral
deposits. Geochemical sampling in the area
was first carried out in 1986, and these
samples were reanalyzed in 2006 using
ICP-MS techniques. However, the samples
were not included in recent INAA
(instrumental neutron activation analysis)
reanalysis programs, and remained the only
area in BC surveyed prior to 1989 that did
not include this important analytical
This project has now reanalyzed
approximately 1150 stream sediment samples
using INAA from the McLeod Lake map
area. Results will be available in early 2013.

McLeod Lake (NTS 093J) Sample Reanalysis (INAA)
By W. Jackaman
Geoscience BC Report 2013-06 presents INAA results for stream sediment samples collected during the original 1985 McLeod Lake RGS program. The McLeod Lake regional geochemical survey was conducted in 1985 (near Prince George) and included the collection of 1152 stream sediment samples. In co-operation with the BC Geological Survey and Natural Resources Canada, samples saved from the survey work were retrieved from storage facilities in Ottawa. A total of 1273 drainage-sediment and quality-control samples were subsequently delivered to Becquerel Laboratories Inc. (Mississauga, ONT) and analyzed by INAA for 35 elements. The data have been carefully checked for analytical quality using blind duplicate samples and control reference material. When determined to be complete and accurate, the reanalysis data were merged with sample site location information acquired from the original survey publication.
