Biogeochemical survey, NTS 63K/16, Snow Lake area, central Manitoba, 1991
(requires an Internet connection)
During a three day period in September 1991, multi-species vegetation samples were collected in the Snow Lake area of central Manitoba. The samples were taken along an exploration grid that is directly over and up to 1.4 km away from the vertical surface projection of the Chisel North Zn-Cu massive sulphide deposit. Twig, needle and outer bark samples were collected from each of black spruce, jack pine and tamarack. Black spruce twig samples comprised the most recent eight years of growth; jack pine and tamarack twigs were the most recent 40 cm of growth. At each sampling site, four branches were collected at chest height from around the periphery of an individual tree. Twig samples from alder and dwarf birch were also collected and comprised the most recent 40 cm of growth. Care was taken to collect twigs of similar diameter, age and general appearance. Samples of twigs, needles and cones were also collected from six black spruce crowns representing the top 35-40 cm of the trees. An interpretation of these data can be found in Geological Survey of Canada Bulletin 426.
