This mineralization can be traced for over 500 metres in outcrop and felsenmeer
. These samples have been prepped and transported for assay.

persistence through glacial periods in the Torngat and Kaumajet Mountains, Quebec-Labrador, as determined by soil weathering and cosmogenic nuclide exposure dating: Canadian Journal of Earth Sciences, v.
A Pionjar "plugger" and ammonium nitrate were used to blast craters 0.6-1 m deep in the thin felsenmeer so that the bedrock could be sampled and assayed.
The fortuitous location of the vertical Eclipse drill holes plus controlled collection of appropriate felsenmeer enabled Lynn to identify a number of distinct lithologic intervals and several markers in the Upper Thumb Mountain Formation.

Exposure ages on felsenmeer
summits are consistent with higher abundances of gibbsite found in summit soils relative to soils in tills and valley floors.
Hills have distinctive banding, based on slope and water, from hillside, dry tots and talus cones, to felsenmeer
(stone ponds), flat areas of frost-shattered rock, and stone circles, down to moist and peaty areas of pingos and ice polygons.
The absence of outcrop, apart from man-made exposures, was partially compensated for by frost-heaved boulders and slabs of bedrock (felsenmeer
), which are present as float in unglaciated areas.
