fragments are composed of dolomite. The majority of the mineralization is disseminated in
the breccia. Locally, syenite enclaves are noted. From 858 m to 945 m, the lanthanides
decrease abruptly to 1-2% (BRC1). There still few zones mineralized (metrics zones of
C1L). Apatite stringer increased. From 945 m to 997.3 m, syenite dominated (SC2). There is
massive carbonatite (30%), with 2-3% lanthanides, mixed with syenite. From 997.3 m to
1076.1 m, a massive carbonatite (C2) is logged. In this interval, the syenite enclave amount
decreased, apatite stringer still noted, and ,locally, presence of Niobium facies (C3NA) are
observed. From 1076.1 m to 1191 m, a breccia facies, depleted of lanthanides (BRC1)
finished the hole.
The REE zone was intercepted in the middle of the hole. The high grade zone was
confirmed. It returned a value of 2.728% TREO / 513m (from 342m) including 0.033%
HREO / 513m. The South transition zone, intercepted previously, returned a value of
1.088% TREO / 287.3 (from 54.7m) and the North transition zone returned a value of
0.989% TREO / 316m (from 855).
