Lafwila (Au, Ag, Pb, Cu)<br />

On this project located at about 300 km to the<br />

South of Dakhla (Awserd province) and following<br />

the encouraging results obtained on the trenches<br />

carried out in 2007 (10.4 g/t Au over 4 m), a<br />

first survey of 4 core drills totaling 531.6 m was<br />

carried out in an effort to recognize the down<br />

dip of gold bearing structures. The targ<strong>et</strong>ed<br />

structures were intercepted with apparent<br />

gra<strong>des</strong> of 6 m for the second drilling and 6<br />

m and 2.5 m for the fourth drilling. Chemical<br />

analyses are carried out on the samples taken.<br />

Madnat As Sadra (Au, Nb, Ta, U, Platinoïds,..)<br />

In Madna As Sadra prospect, located at 200 km<br />

SE of Dakhla (Awserd province), the geological<br />

control of aeromagn<strong>et</strong>ic and spectroardim<strong>et</strong>ric<br />

anomalies permitted to highlight, in El Ghassaliat<br />

sector, quartzose structures with index gra<strong>des</strong><br />

ranging b<strong>et</strong>ween 0.2 and 0.8 g/t Au on m<strong>et</strong>ric<br />

thickness and iron ore carbonatites with gra<strong>des</strong><br />

reaching 0.5 % Nb 2 O 5 and 470 ppm Ta 2 O 5 , in<br />

Drag sector, and 0.4 % Nb 2 O 5 ; 520 ppm Ta 2 O 5<br />

and 350 ppm U 3 O 8 in Al Farnan sector.<br />

Tichka-Est (Au)<br />

The project of Tichka Est, situated at 140 km<br />

South of Marrakech, showed gra<strong>des</strong> ranging<br />

b<strong>et</strong>ween 1 and 14 g/t Au at the occurrence of<br />

the first sampling. Following these encouraging<br />

results, a d<strong>et</strong>ailed geological survey at 1/500,<br />

covering an area of 24 acres, and a lithogeochemical<br />

sampling with results ranging<br />

b<strong>et</strong>ween 0.1 and 33 g/t Au were carried out.<br />

A geophysical study showed that the structure<br />

is deeply rooted. The alluvial prospecting<br />

conducted in this prospect yielded gra<strong>des</strong><br />

reaching 22 g/t Au.<br />

Bas Draa (Au)<br />

In the Bas Draa inlier (Guelmim, Tan Tan and<br />

Assa Zag provinces), prospecting continued in<br />

the Upper and Lower Proterozoic formations in<br />

Ayoun Lghoumane prospect. Samples taken<br />

in the iron ore quartzose structures encased in<br />

sandstones and Pl pelites or in copper indices<br />

borne by quartz veins encased in Infracambrian<br />

bed formations yielded indices in gold (
