MINING  
 
 

MIDROC Gold is also planning to mine the deeper level resources of the present open pit mine, for this purpose an underground project is in progress. To date more than 3km of underground workings have been done, and the deeper resources have been evaluated for a minable vertical depth of 115m and a strike of 350m. The evaluation was done by 50m x 25m grid core drilling, which was conducted from underground cubbies. The ore bodies are open both down dip and along the strike, exploration drilling will continue for the deeper levels and other lenses that have not yet been evaluated.

Cut-and-Fill mining method has been selected and confirmed by an international consultant; the corresponding mine design has been done. The project is presently preparing the relevant infrastructures required for a full scale underground mine, which is planned to commence in 2007/2008. With the additional resources to be upgraded and evaluated in 2006/2007, the planned life-of-mine of the underground mine is up to 2018.

GOLD PRODUCTION & MARKETING  
 
 

The Legadembi Gold Mine is an open pit operation with annual production of 1.6 million tones of ore. An underground mine is currently being developed beneath the open pit to extract deeper level ore - the commencement of full-scale underground mine operations is planned for 2007/08.

Gold is recovered in a Carbon in Pulp (CIP) technology process plant. Yearly average production is about 4500kg of gold-silver doré (fine gold production is in the order of 3,500kg). The average fitness is 78% for gold and 21% for silver; the remaining 1% accounts for other elements of no commercial interest. The gold doré bars are shipped to Argor Heraus refinery in Switzerland; the gold is then refined and sold to Commerzbank in Zurich Switzerland.

EXPLORATION  
 
 
MIDROC Gold Mine PLC owns and operates the Legadembi Gold Mine, which is located 500km south of Addis Ababa, Ethiopia. MIDROC Gold is actively involved in exploration projects, which are located near the mine (Adola-Legadembi Exploration License - ALEL), and in another area some 600km northwest of Addis Ababa (Metekel Exploration License - MEL).

The ALEL is valid for three years, effective March 2005. It covers 485 sq km and is located at the center of the known Adola Gold Belt, situated in one of the greenstone belts of the southern part of the country. There are currently two potentially economic projects within MIDROC Gold’s portfolio of ALEL, namely East Sakaro and Werseti Projects. Exploration carried out at East Sakaro has outlined an inferred resource of about 2 million tonnes of ore grading at 9.8g/t, giving a gold content of about 20,000kg (645,000 ounces). Early stage exploration works at Werseti delineated both high and low grade zones of gold mineralization. The low-grade intersections vary from average gold grades of 0.8g/t over 12m to 2.6g/t over 25m. The high-grade intersections are in the order of 5g/t to 49g/t of gold.

Both projects lie on the newly identified Tibiro-Sakaro-Ulaulo mineralized prominent shear zone, which extends for more than 20km, and are considered to have considerable upside potential. A 5-Year Strategic Exploration Plan (2005 to 2010) is in place to advance the East Sakaro and Werseti Projects to feasibility within the next five years. Intensive trenching, geophysical surveys and prospecting drilling are also planned to test other targets already identified, with the aim of generating further drill-ready targets.

The MEL covers 1964 sq km and is also valid for three years, effective March 2005. It is situated within the Tulu-Dimtu-Baruda Shear Belt of the western Ethiopia greenstone belt, known for numerous occurrences of gold and poly metallic minerals. Four key exploration gold targets of significant potential have been identified to date, namely Egambo, Aware-Doshe, Epar and Aydot-Fiti. Two other targets, namely West Tangoy and Meb-Anjakoya, have also been identified for copper (Cu 1.6% to 15%) and rare metals (Nb 31213ppm and Ta 7185ppm, in concentrates), respectively.

At Egambo gold mineralization outlined on surface over a strike length of 600m, trenches returned 1.6g/t over 9m up to 1g/t over 59m; mineralization open to the north. At Aware-Doshe five gold-in-soil anomalies outlined over a strike of 3.4km, trenches returned 1.7g/t over 10m, 6.8g/t over 3m and 10g/t over 1m; mineralization open at both ends. At Epar grid-based soil survey outlined gold-in-soil anomaly 500m in length and 40m to 80m in width, eight chip samples returned from 1.4g/t to 11.5g/t gold; mineralization open at both ends. At Aydot-Fiti skarn-type gold-copper mineralization identified over a 4km strike, chip rock samples returned up to 6.3g/t gold; mineralization open at both ends. All these gold targets have potentials for moderate to large tonnage, low to medium grade, open pittable gold deposits.
