Annual Report 2008 - Office National des Hydrocarbures et des Mines

MINING EXPLORATION
The year 2008 was marked by the diversification
of the research themes and the concentration
of the works on the most promising areas,the
strengthening of the conceptual targeting to
help emerge new objectives, and the renewal
of the ISO 9001-version 2000 certification of
the mines laboratories.
During FY 2008, the mining exploration works,
carried out in a mining domain made up of 855
permits, focused on 26 objectives distributed
as follows : precious metals (16), base metals
(8) and rocks and industrial minerals (2).
As in the previous years, works were carried
out on the most promising zones of the Anti-
Atlas, Haut-Atlas and Jebilets-Guemassa with
a sustained research effort in the southern
provinces. Globally, the interest shown in the
projects of Azouggar N’Tilili (polymetallic-gold),
Glibat Lafhouda and Twihinate (Fe, Nb, Ta, U
and light rare earth elements) and gold structures
of Lafwila was confirmed. A new prospect was
also identified at Lamlaga (Fe, Nb, Ta, U and
light rare earth elements).
Following the conclusive results of the
orientation study carried out on Azouggar N’Tilili
(polymetallic-gold) project, an open invitation to
bid was issued for the project transfer.
Concerning the Mine laboratory activity, in
addition to the production front, the year 2008
was marked by the renewal of certification
through a follow-up auditing, in accordance with
ISO 9001 version 2000. It should be recalled
that the certification was obtained in 2007.
The results obtained by subject and project are
as follows :

Precious metals
Azouggar N’Tilili (Au, Pb, Zn, Ag)
In Azouggar N’Tilili polymetallic-gold prospect,
situated SW of Low Draa, at 50 km to the East
of Tan Tan city, a synthesis of the results of all
works carried out was prepared. The resources
highlighted are estimated according to two
variants : 452 500 t to 5.8 g/t Au ; 5.4 % Pb ;
5.7 % Zn and 44.8 g/t Ag for an average
thickness of 1.4 m or 1 105 600 t at 3.6 % Zn ;
2.3 g/t Au ; 2.2 % Pb and 19 g/t Ag for an average
thickness of 4 m. An international invitation
to tender was issued for this project transfer.
Glibat Lafhouda (Nb, Ta, Ree)
In Glibat Lafhouda prospect, located at 75 km
SW of Awserd, a geological survey over 10
sq km at scale 1/1000 and a reconnaissance
survey by gravimetry over 10.2 sq km were
conducted with a view of achieving the deep
rootedness of massive carbonatite zones and
iron oxides.
A second survey of 8 core drills totaling
1 042 m was carried out in order to better
delineate the geometry of mineralized bodies.
The results obtained so far are as follows :
