This tool is designed to use
the vast digital datasets in SIGEOM, in order to retrieve all relevant
parameters for a given ore deposit model. A wide variety of parameters
may be selected, according to the type of ore deposit under study:
for example, among the wide range of elements accessible in SIGEOM,
selected features may relate to the presence of alteration minerals
reported in some of the 235,000 outcrop descriptions, or to
the presence of anomalous grades of specific metals in some 129,000 drillholes
or in roughly 11,500,000 secondary environment analytical results
(lake sediments, soils, stream sediments, tills). External data
may also be integrated, such as topographic lineaments traced on
Landsat images, or any other linear or planar anomaly derived from
geomagnetic or gravity images.
Gold potential in Archean rocks of the Baie-James region
A favourability study of the potential for orogenic (or mesothermal) gold deposits in the Baie James region was completed. The study resulted in the definition of 735 high-favourability zones and 114 unstaked targets as of November 1, 2007. A gold favourability map at 1:500,000 scale was produced.

Assessment of base metal potential in the
Abitibi region
The Deparment has also published an overview assessment
of base metal potential in the Abitibi sub-province and the Frotet-Evans
belt. This is the first time in Québec that an area of this
size has been studied, with such a large range of integrated data
and such high-resolution treatment. This large-scale survey covers
all the Archean volcanic rock located between the 47th
and 51st degrees of latitude (figure 1).
The survey is intended to define and document 150 target areas
in the territory covered that offer the most potential for new discoveries.

by the assessment of base metal potential in the Abitibi region.
The final assessment will include:
- A 1:500,000 map of the sector, together with roughly;
- 120 1:50,000 maps produced using ArcGIS software
and available on DVD in PDF format;
- Intermediate products in digital format will also be available,
such as a lithological map of Abitibi using closed polygons, based
on the 1:20,000 and 1:50,000 maps available for the
sector as a whole.
