Following the 1991 hydro- and biogeochemical orientation study of the Baie Verte Peninsula, Newfoundland, a sampling scheme was designed to collect stream waters and vegetation from approximately 150 sites at an average density of 1 sample per 2 km2. In 1992, samples were collected in an area extending from Devil’s Cove to the Brass Buckle gold deposit 20 km to the south on the Baie Verte Peninsula, northern Newfoundland. The outer bark and the most recent 10 years of growth of twigs were collected from black spruce trees. Results from the orientation survey the previous year indicated extraordinarily high metal concentrations in both tissue types, so both were collected. In addition, there are subtle differences for a few elements due to the ability of spruce to fix elements in different tissue types. Vegetation samples were selected from a site at least 50 m from a highway, or 10 m from a little-used track to minimize roadside contamination. Two bottles of water were collected at each site, one that was filtered and acidified for trace element analysis and one for determination of pH, conductivity, organic carbon and selected anions. At certain sites, a third bottle was collected for gold determination. When a stream water sample was not available at a particular site, a lake water sample or occasionally a bog water sample was substituted. The spruce twig data are published in Geological Survey of Canada Open File 2951. The spruce bark and water data have not yet been published.

The geographic extent of the survey is defined by the following polygons:
Covers part of NTS 12H/16 (Baie Verte) and 12I/1(Fleur de Lys) on the Baie Verte Peninsula, northern Newfoundland. Highway 414 runs east-west in the central part of the study area. Parts of Ming’s Bight and Baie Verte lie in the northern part of the study area.
