This helicopter supported program was conducted between July 5-July 25, 2011.
Notice the words " The main chromite deposit is associated with such northeast-aligned intrusive rocks near the Noront Resources Limited Esker Camp in the southeastern part of the report area "...
Notice this in the report:
The 98 drift-sediment samples collected in the field are being processed for indicator minerals including gold, kimberlite (diamond), base metals and rare earth elements. Digital data for bedrock outcrops are currently under preparation for release as a Miscellaneous Release—Data (MRD).

A helicopter-supported program of surficial geology mapping and drift sediment sampling was
conducted in the McFaulds Lake area of the James Bay Lowland, northern Ontario, between July 5 and
25, 2011 (Figure 23.1). The project area covers the region of extensive mineral exploration known as the
“Ring of Fire”, an area where high-grade chromite ores and other metallic deposits have been discovered
in recent years. The bedrock consists of Precambrian granitic to gneissic suites with metavolcanic deposits
and mafic to ultramafic intrusive rocks (Ontario Geological Survey 1991) (
see
Figure 23.1). The main
chromite deposit is associated with such northeast-aligned intrusive rocks near the Noront Resources
Limited Esker Camp in the southeastern part of the report area (
see
Figure 23.1). Along the eastern margin
of the report area and further to the east, the lowland is underlain by Paleozoic carbonate bedrock (
see
Figure 23.1).
