As a part of the BCM Group, BCM Investments Limited is a successful mining company in Africa with a diverse portfolio of assets. The company was established by Paul List, an Australian/Ghanaian with extensive experience in the mining industry. The company’s strategy is to acquire and develop high-quality mines in Africa, while creating value for its shareholders, stakeholders and host communities.
The company’s first acquisition was Adamus Resources Limited, a gold mine in Ghana, in 2016. The company then expanded its presence in Mali by acquiring Segala Mining SA, a gold mine, in 2018. In 2019, the company bought 80% of Samira Hill SA, a gold mine in Niger, from the government of Niger. The company also acquired Northern Ashanti Mines Co. Ltd., a gold mine in Ghana, in 2020. The company has an advanced mine in Burkina Faso, which is expected to commence production by the end of 2023. Furthermore, the company has exploration licenses in Sierra Leone and Liberia.
The company’s Adamus mine produces and sells around 250,000 ounces of gold per year, and the company aims to increase its production from its other mines. The company employs around 3,000 people, with 90% local workers and 60% local managers. The company is dedicated to operating responsibly and sustainably in Africa
Adamus Resources Limited
Adamus Resources Limited (Nzema Gold Mine) is a gold mining company located in the Western Region of Ghana. It is about 300km from the capital city Accra and 80km from the port city Takoradi by road. The mine is owned by BCM Investments, which acquired it from Endeavour Mining in 2017. It is the first mine to be owned by BCM Investments. The company has a 90% stake in the mine, while the Government of Ghana owns the remaining 10%.
PRODUCTION
HOW WE MINE AND PROCESS ORE
Mining operations started in November 2010 and commercial production in April 2011. We are currently using conventional open pit mining method and mine the ore ourselves. We process the ore by Carbon-in Leach (CIL) technology. Our processing plant can handle oxide, transition, and primary ores. The plant’s capacity depends on the ore hardness: 2.1 Mtpa for softer oxide ore and 1.6 Mtpa for harder transition and fresh ore. We have about 1,228 workers, mostly Ghanaians (99%) and locals (59%).
GEOLOGY
THE ROCKS THAT HOST GOLD DEPOSITS IN GHANA
The rocks that host gold deposits in Ghana are Palaeoproterozoic rocks of the West African Craton. These include the Birimian Supergroup, a series of meta-volcanic and meta-sedimentary rocks, the Tarkwaian Group, fluvial meta-sedimentary rocks, and various gabbroic to granitic intrusive.
Gold mineralization in the Birimian Supergroup is related to mesothermal quartz veins and structural control, while the Tarkwaian Group hosts both mesothermal shear-hosted and palaeoplacer gold deposits. Our Project area has Birimian Supergroup rocks with minor granitic intrusions, surrounded by large granitoid bodies to the west and east, and some Tarkwaian Group rocks in the east.
EXPLORATION
OUR GOAL IS TO DISCOVER MORE THAN 350K OZ OF GOLD FROM 2021 TO 2023
Our Nzema Gold Project covers about 369.95km² in Southwest Ghana. It consists of 4 Mining Leases and 8 Prospecting Licenses with 2 JV Permits. We have a lot of exploration potential on these lands and we are looking for more economic gold deposits to extend our mine life. We also have a large resource of 973K oz @ 1.80g/t Au of untapped refractory Salman ‘sulphide’ ore. We are studying the best way to treat this ore.
SEGALA MINE
Segala Mining, a subsidiary of BCM Investments Limited, operates in Tabakoto, near Keniéba in southern Kayes region. It acquired the mine from Endeavour Mining in 2018 and has two permits: SEMICO and MIKO. SEMICO has one open-pit and two underground mines, while MIKO has two open-pit mines. BCM Investments owns 80% of the share capital and Mali owns 20%. Segala Mining processes the ore from MIKO deposits as part of their development.

PRODUCTION
The mine has both open pit and underground operations. Mining activity is by owner mining.
The mined ore is processed by Carbon-in-Leach (CIL) technology. The processing plant is designed to treat oxide, transition and fresh ores. The design throughput treatment rate is 1.7 Mtpa.
EXPLORATION
TURBIDITE HOSTED VEIN OROGENIC GOLD DEPOSITS
Host Rock: Turbidity sedimentary rock (tourmaline front absent)
+/- Associated with granite (improved heat flow & stronger hydrothermal systems)
Each deformation of the Eburnean Orogen contains gold and is accompanied by alteration.
Four dominant auriferous structures have been identified.
Au zone grade and thickness Improves with multiple structures (Cross Structure Model)
Northern Ashanti Mines (Konongo Gold Mine)
Northern Ashanti Mines (Konongo Gold Mine) is located around 150 km from Accra, Ghana and is currently under re-development.
The project comprises two leases totalling 195 km², over 12km of mineralized strike length and sixteen known gold deposits.
The Northern Ashanti project has a huge untapped surface and underground potential.
BCM Investments Limited acquired the mine in 2021. The initial required investment to facilitate mining and processing is around USD 80 million.
Small-scale production is set to restart in 2023
SAMIRA HILL
Samira HiII Gold Mine is located approximately 140km west-southwest by road from the capital city of Niamey in the Tillabery region. It is currently the only commercial gold mine in Niger.
BCM Investments acquired the mine in 2019, and it has a shareholding of 80% while SOPAMIN holds the remaining 20%.
The mine employs open pit mining methods and uses a plant and a water dam with a capacity of 6’000t/d and 4’000’000m³, respectively.
Samira Hill has ten exploration permits for an area of 1’456 Km² and two exploitation licences for an area of 21,7 Km².
The mine operation is currently oxide only. A large potential for transition and sulphide ore exists below the current pits.
It has a current workforce of 454.
