Deuventi Holdings

International Mining

In 2024, global gold demand (including over-the-counter transactions) reached a historic record at 4,975 tons with a total market value of $382 billion. Amid rising market volatility and increased global risks, central banks worldwide have continued large-scale gold purchases, which underscores gold’s crucial role in international reserve portfolios.

Deuventi owns two gold mines in Tanzania and Uganda respectively.

Deuventi’s two major gold mining

Deuventi’s two major gold mining sites in Tanzania’s Lindi region are situated by the Mbwemkuru River and its tributaries. These ancient sandstone formations, alluvial deposits, riverbeds, and placer layers exhibit high gold content, facilitating extraction-friendly conditions. The mines demonstrate strong competitiveness and, according to on-site geological assessments, hold significant exploration potential for further discoveries.

The licensed mining area (Permit No. PL 12781/2024) spans 10.37 square kilometres. Geological surveys confirm total gold reserves of 80 million tons, with mineral content reaching 2.4 million tons. The site currently produces 4 tons of gold annually, and based on existing reserves and extraction rates, the estimated mine life is approximately 60 years. This indicates a stable long-term mining prospect and significant commercial value, ensuring sustained gold production to support the global market for years to come.

Tanzania possesses exceptional geological conditions for gold mineralisation. The primary rock gold deposits are concentrated in the eastern part of northern Lake Victoria and southern Archean greenstone belt, a world-class gold mineralisation zone. Additionally, gold deposits are also found in the southern and southwestern regions of the Proterozoic Ubendian Belt. The main types of gold mineralisation include shear zone-type deposits, quartz vein-type deposits, banded iron formation-hosted gold deposits (strata bound type). These gold mineralisation types are highly favourable for formation and enrichment within the local geological structures.

Uganda gold mining

The Uganda gold mining area is located in the Busia region of eastern Uganda, bordering Kenya to the east. The mining area holds two mining licenses, covering a total area of over 400 square kilometres.

The topography of the region is relatively flat, with a slightly elevated central-southern section and lower northern, eastern, and western parts. The southern highlands form the surface watershed between Lake Victoria and Lake Kyoga. The highest elevation reaches 1,222 metres, while the lowest point is 1,090 metres, resulting in a height difference of 132 metres.

The mining area is located within the tropical savanna climate zone in the central part of the Central African Plateau. Although it is close to the equator, its high altitude, extensive river networks, and numerous lakes contribute to abundant rainfall, lush vegetation, and a mild climate, earning the title of “The Pearl of Africa”.

The annual temperature remains relatively stable, with small seasonal variations but significant day-night variations. The average annual temperature is 22.3°C, with October being the warmest month (around 23.55°C) and June the coolest (around 21.4°C). There are two distinct rainy seasons each year - short rainy season from March to May, with an average monthly rainfall of 250-300mm, and long rainy season from August to November, with an average monthly rainfall of 150-200mm. The long-term average annual rainfall ranges from 1,400 to 1,600mm, while the potential annual evaporation is 1,730mm. The seasonal variations in temperature, humidity, and wind are minimal, with no extreme fluctuating and unpredictable wind patterns, or hazardous weather conditions.

Deuventi utilises open pit mining technology, leveraging large-scale excavation equipment to efficiently extract shallow mineral deposits, thus enhancing mining efficiency. The well-established cyanidation method is employed during the gold extraction process to ensure high recovery rates from ore. Additionally, advanced automation control systems are integrated to monitor and optimise production processes in real time, ensuring operational stability and efficiency while further enhancing gold yield and quality.
