• Large (>40Mt), lower grade VMS type deposits in older Proterozoic terrains (Gamsberg, Asmara)
– Complex mineral paragenesis; complicated metallurgy
• Smaller (~5 - 10Mt), higher grade MVT type carbonate hosted deposits (Benue Valley, Bouk
Dema, Fej Lahboum, Gite de l’Est)
– Central processing facility and more extensive infrastructure

Opportunity to re-start mining at past producing mines
mining stopped at a time of low metal prices; these mines have established resources in situ and upside for more
Bougrine concentrator on care and maintenance
Centrally located with capacity up to 2,000 tpd
Ready Market in Europe
World shortage of good quality concentrate
Clean concentrate commanding high prices in the European smelting market
Bou Grine product sold to a number of European smelters
Competitive mining code and stable fiscal regime
Good existing infrastructure
power, water, rail, concentrate handling, extensive good quality geodata and effective government support
Little modern exploration and excellent exploration potential

March to September 2007: Phase 1 - Verification
Drilling completed at Gite de l'Est. 10 drill holes totalling 3,404.5m. Drilling results confirm and verify the previous O.N.M. drilling results, with some zinc assays in cores looking considerably better.
June to October 2007: Discovery of cores and pulps from original ONM drilling programme used for earlier COMINO (2001) resource estimates.
Significant uplift in zinc results (>40%) from reanalyses of the first batch of these.
December 2007: Inferred Mineral Resource estimate for Gite de l’Est of 8.836 million tonnes

21.66% BaSO
4 and
(JORC (2004) - in situ value of the mineral resource is estimated to exceed US$925 million at December 2007 metal prices.

• Limited exploration to date
• Three targets:
1. Old workings for lead-zinc-barite in galleries in the hillside – mining stopped at the water table
2. High grade assays in drilling near the
Algerian border
S12 – 29 m @ 7.16% Zn
S36 – 3.3 m @ 10.5% Pb
S37 – 4.9 m @ 45% Zn
S50 – 2.0 m @ 23.5% Zn
S51 – 5m @ 15.5% Zn, 2.0% Pb

Past small-scale producer of high grade Pb – Zn mineralisation (closed in
1929)
On the same mineralised basin margin structure as the nearby (4 km)

• Bou Grine is Tunisia’s largest known zinc/lead deposit to date.
• Discovered in 1981, the Bou
Grine deposit was estimated, in
1985, at 7.3M grading 2.4% Pb and 9.7% Zn using a cut-off of
4% Zn.
• Bou Grine Mine operated by
Breakwater Resources closed in
September 2005.

Opportunity to fast track getting back into production via a possible deal with
Breakwater to toll treat or purchase the mill
Fej Lahdoum was supplying 15% of mill feed until closure in 2005
Rail access from Bou Jabeur and
Lorbeus to the Bou Grine Mill
Rail from mill to the port and concentrate storage facility in Tunis

• Positive indications for MVT mineralization of lead and zinc.
• Office National des Mine reworked soil geochemical survey data shows very positive lead zinc anomalies.
• A positive residual gravity is partly coincident with the soil geochemistry anomalies which track linear satellite trends
• Maghreb’s geology re-mapping showed:
– prospective near basin margin facies;
– evidence of extensive hydrofracturing and fluid flow
– lead mineralisation at surface

Tan Chaffao location and geology:
• acid volcanics (porphyritic rhyolites)
• overlain by a volcano-sedimentary unit
(volcanic tuffs, with mafic volcanics)
• major fault structures traverse the area.

The polymetallic (Zn, Pb, Cu, Au) mineralisation of Tan Chaffao:
• discovered in 1971 and explored by O.R.G.M teams
• geological and geophysical studies and a 10-hole drill programme.
• drilled to depths of between
100m to 200m
• several mineral-bearing zones over a strike length of 1,450m
• lenses - length from 50m to
300m; widths between 0.6m and
21m
24 September 2008 FINEX '08, LONDON 42
Verification work programme by Maghreb
Tan Chaffao
• five drillholes (MTC001 – MTC005), for a total of 823 metres
• mineralisation in an altered sulphidic quartzite below chlorite-sericite schists.
• assay results below expectations based on previous O.R.G.M. data.

• gravity soil geochemistry surveys identified some small-scale gravity highs with coincident elevated copper and gold in soils.
• high level of expenditure operating in the remote Tan Chaffao area, slow progress of available contractors and disappointing initial results
• DECISION terminate further exploration over this permit.
