on the South contact returned a low value of 0.636% TREO / 191.8 m that may be evaluated
in a low grade / high volume mining technic.

13.5.9 2012-REE-037
The 2012-REE-037 is situated in the Center-West area of the REE zone (MTME 255874.00:
MTMN 5378202.00). It was drilled at 028° (true North) with a dip at -50°. The objective
was to characterise the core of the REE zone with a drilling pattern of 100m x200m. The
overburden is 6.8 m thick. From 6.8 m to 69.5 m, the Trenton limestone covered the
carbonatite. The carbonatite begins with a strongly altered breccia facies (BRC1L) (hematite,
chlorite and siderite) down to the depth of 132.2 m. From 132.2 m, the paleo-weathering
alteration disappeared and the fresh carbonatite breccia facies (BRC1L) is logged down to
321 m. From 321 m to 798m, large interval of breccia (BRC1L) and massive (C1L) (Figure
17) carbonatite facies are layered.
The hole stays in the mineralized carbonatite and returned value of 2.263% TREO / 728.5 m
(from 69.5 m) including 0.031% HREO / 728.5 m.
