Till Ontario 1996

Till sampling survey, NTS 42A, 41P, northeastern Ontario, 1996.  


Ontario Ministry of Northern Development and Mines, Ontario Geological Survey

Survey Description

216 C-horizon till samples were collected along the western extension of the Larder Lake-Cadillac Break, Matachewan area, northeastern Ontario in 1996 as part of a regional and property-scale sampling survey. The regional samples were collected at a density of just under 1 sample per 2 km2. The data are published in Ontario Geological Survey Open File Report 5957.

Data Description: Paper report with partial data lists. Complete digital data released as MRD-29 (Miscellaneous Release-Data 29).

Quantities Analysed: <0.063 mm fraction by INAA for 35 elements; by ICP-MS after aqua regia digestion for approximately 50 elements.

Geochem Plots Available: Maps showing regional and property-scale distribution of Au, As, and Sb in till.

Other Analyses: Pebble counts; heavy mineral concentrate for gold grain analysis.

Project History

1996-1997 Northeastern Ontario till sampling survey carried out in 1996.
  Regional and property-scale till samples were collected along the western extension of Larder Lake-Cadillac Break in 1996 in the Matachewan area, northeastern Ontario. The objective of the study was to further refine the aerial extent of elevated regional background for gold and associated elements determined in a previous till sampling survey in the area and to suggest concentrations of metals in till that may point to economically significant bedrock deposits. The detailed property-scale sampling at the Ashley Mine and the Matachewan Consolidated Mine documented the magnitude, shape and character of dispersal trains originating from known gold sources. This information will be applied to the interpretation of the regional till sampling data set. The data are published in Ontario Geological Survey Open File Report 5957.
