Survey Description


In 1983 a vegetation survey was carried out in the vicinity of the Agassiz deposit, in the Lynn Lake area, Manitoba.  Several sample types were collected to determine what species could be used as a tool to explore for buried gold mineralization.  Samples were also collected at Dot Lake, Arbour Lake and Frances Lake.

The data are published in Manitoba Department of Energy and Mines Open File Reports OF84-1 and OF85-6 as detailed below:

 

Area Sample Type Publication Comments
Agassiz deposit black spruce twigs and needles (n=43) Open File Report OF84-1 (Zn, As, Sb, Au by INAA) orientation samples; useful for finding Agassiz-type gold mineralization
Agassiz deposit Labrador tea leaves and twigs (n=67) Open File Report OF84-1 (Zn, As, Sb, Au, Pb by INAA) not useful for finding Agassiz-type gold mineralization
Agassiz deposit humus/humified peat (n=28; + 40 samples from 7 cores) Open File Report OF84-1 Cu, Pb, Zn, Mn, Au by AAS; Zn, As, Sb, Au, Pb by INAA) may be useful for finding Agassiz-type gold mineralization
Dot Lake, Rushed showing black spruce twigs and needles (n=46) Open File Report OF84-1 (Cu, Pb, Zn, Mn by AAS; As, Au by INAA) based on results from the orientation survey, the sampling area was expanded
Arbour Lake black spruce twigs and needles (n=31) Open File Report OF84-1 (Cu, Pb, Zn, Mn by AAS; Au, As by INAA) based on results from the orientation survey, the sampling area was expanded
Frances Lake deposit black spruce twigs and needles (n=56) Open File Report OF84-1 (Cu, Pb, n, Mn by AAS; As, Au by INAA) orientation survey to examine the signature of massive sulphide deposits
Agassiz deposit black spruce twigs and needles (n=368) Open File Report OF85-6 (Cu, Pb, Zn, Fe, Mn by AAS and As, Au by INAA for the non-orientation samples; republishes from OF84-1 Zn, As, Sb, Au by INAA for the orientation samples) includes the 43 orientation samples previously published in OF84-1; new data for the non-orientation samples

The geographic extent of the survey is defined by the following polygons:

  • Covers part of NTS 64C/15 (Cockeram Lake), the Agassiz deposit in the Lynn Lake area, northern Manitoba.  The centre of the study area is located approximately 7.8 km northeast of the town of Lynn Lake and just east of Dot Lake.  Highway 391 is located about 2.5 km south of the study area.

  • Covers part of NTS 64C/15 (Cockeram Lake), the Rushed showing (Dot Lake) in the Lynn Lake area, northern Manitoba.  It is bounded to the north by Dot Lake and the centre of the study area is located approximately 6 km northeast of the town of Lynn Lake.  Highway 391 is located about 1.7 km south of the study area.

  • Covers part of NTS 64C/15 (Cockeram Lake), near Arbour Lake, northern Manitoba.  It is bounded to the southeast by Arbour Lake.  Lobster Lake and Desieyes Lake are located within 5.5 km west of the centre of the study area.

  • Covers part of NTS 64C/14 (Lynn Lake) near Frances Lake, northern Manitoba.  The study area is bounded to the southeast by Frances Lake and is located just south of Margaret Lake.  The centre of the study area is located approximately 4.5 km southwest of the town of Lynn Lake.
