13.5.10 2012-REE-038
The 2012-REE-038 is situated in the South-East of the REE zone (MTME 256218.97:
MTMN 5378001). It was drilled at 031° (true North) with a dip at -50°. The objectives were
to continue the drilling pattern of 100m x 200m and delimit the South contact. The
overburden is 10.20 m thick. From 10.20 m to 38 m, the Trenton limestone covered the
carbonatite. The carbonatite begin with a REE-poor dolomitic breccia facies (BRC2) down
to 183 m. From 183 m to 252 m, a massive, medium grain textured calcitic facies (CCA) is
observed. An ankeritic and dolomitic breccia facies (BRC1) followed down to 373.6 m.
From there, the dolomitic carbonatite become massive (C1L).
The mineralization appeared at the depth of 357 m in a breccia facies. The south contact was
limited by the low grade carbonatite returning a value of 0.600% TREO / 319 m (from 38
m.). The REE zone returned a value of 1.077% TREO / 45 m (from 357 m) including
0.016% HREO / 45 m.
13.5.11 2012-REE-039
The 2012-REE-039 is situated at the South-West of the REE zone (MTME 255797.05:
MTMN 5378244.16). It was drilled at 028° (true North) with a dip of -50°. The objective
was to complete a definition drilling pattern of 100m x 200m. The overburden is 15.90 m
thick. From 15.90 m to 55.70 m, the Trenton limestone covered the carbonatite. The
