VoltVision, a UK-based specialist in digitised industrial power networks, says it has completed the first phase of a program to digitise the power networks at Endeavour Mining’s six West African gold mines.

The project has been designed to help maximise the efficiency of Endeavour’s electrical power systems, enabling it to improve power quality, increase uptime and reduce CO2 emissions, while lowering energy consumption and operating costs, VoltVision said.

Endeavour has identified significant power efficiency gains and cost savings as the project has been rolled out. VoltVision has progressed to Phase 2 of the roll-out, which is focusing on condition monitoring, failure prevention and further power reduction analysis.

Back In May 2022, VoltVision announced that the first phase of a pioneering energy efficiency and operational enhancement project at Endeavour Mining’s Houndé Mine in Burkina Faso had been completed.

VoltVision says its V-Cube data modules represent the only commercially available electrical data analytics system in the mining industry able to be both installed, operated and managed remotely, requiring no site visits from Voltvision personnel.

Manoli Yannaghas, VoltVision Managing Director, said: “Because our technology is plug-and-play, Phase 1 was installed successfully by Endeavour’s own engineers, without any site visits from us or disruption to production. It also proved its suitability for remote and hostile environments.”

VoltVision’s digitisation program works by retrofitting its V-Cube data modules to virtually any electrical asset, connecting them to the cloud and VoltVision’s ViVid platform. The V-Cube extracts detailed system and/or asset performance data 24/7, which is then stored in the cloud, reducing the cost of in-situ historians databases, the company says. Its advanced analytical capabilities convert this data into actionable information for use by management teams, which is available through dashboards and alerts.

Yannaghas added: “Digitising industrial power networks, including high voltage, can deliver immediate savings of up to 15% of annual static energy costs, plus a host of benefits including greater reliability and lower carbon emissions.

“Our solution converts previously stranded assets into actively monitored elements of a cloud-based IoT system capable of analysing massive amounts of data with minimal infrastructure investment. This gives users unprecedented visibility of power consumption, quality, emissions and costs, so they can make intelligence-based management decisions.”

Endeavour looks to consolidate West Africa gold sector with SEMAFO acquisition

Endeavour Mining is to acquire fellow West Africa-focused gold producer SEMAFO in a friendly, all-share deal that, Endeavour says, will create a top 15 global gold producer and the largest yellow metal miner in West Africa.

The deal, which both sets of Board of Directors have unanimously approved, values SEMAFO at C$1 billion ($694 million) and comes with a 27.2% premium based on the 20-day volume weighted average price of both companies for the period ended March 20, 2020. It would see existing Endeavour and SEMAFO shareholders hold around 70% and 30%, respectively, of the combined company on a “fully-diluted in-the-money basis”.

Such a transaction comes less than six months since SEMAFO suspended operations at its Boungou open-pit mine, in Burkina Faso, following a deadly attack on a public road in the Est region. This led to a seven-week suspension of the mine in 2019. This incident followed on the heels of a pit wall failure at its Mana mine, also in Burkina Faso, in August, that led to a 10-week suspension.

Endeavour, meanwhile, had its hopes of merging with fellow Africa gold producer, Centamin, dashed earlier this year after Endeavour President & CEO, Sebastien de Montessus, said the quality of information received during the accelerated due diligence process had been insufficient to allow the company to be confident in proceeding with a “firm offer” for Centamin.

On a pro-forma basis, a combined Endeavour and SEMAFO would have more than 1 Moz of gold production in 2020 (based on current company guidance), placing it among the top 15 gold producers globally, while all-in sustaining costs (AISC) would be below $900/oz, placing it within the bottom third of the industry cost curve, the companies said.

Assets would include the Ity, Houndé, Agbaou and Karma mines from Endeavour (which produced 651,000 oz at an AISC of $818/oz in 2019) and the Boungou and Mana mines from SEMAFO (which produced 340,900 oz at an AISC of $724/oz in 2019).

Endeavour-SEMAFO would also have 10.5 Moz of reserves and 20.7 Moz of measure and indicated resources (inclusive of reserves), plus an additional 6.3 Moz of inferred resources.

It would be strategically positioned as the largest gold producer in both Cote d’Ivoire and Burkina Faso, which account for two-thirds of the highly prospective West African Birimian Greenstone Belt, they said.

It would also consolidate the Houndé belt in Burkina Faso to create a “world-class mining district with two mines, exploration upside and strong future development potential”, they said.

Endeavour said influential investor La Mancha will continue to be a highly supportive cornerstone shareholder, committing to invest $100 million, although decreasing its overall stake from around 31% in Endeavour to about 25% in the combined entity (calculated on a pro-forma basis using current share prices), to “provide for a larger free float and greater stock liquidity”.

These M&A discussions have been going on for some time, according to Endeavour.

In early 2019, both companies engaged in a mutual dialogue in order to evaluate the merits of a business combination. The dialogue included extensive mutual due diligence as well as discussion of potential terms of a transaction, with a final proposal in May 2019. At that time, it was not possible to agree on terms which appropriately shared the risks and rewards of a combination.

In early 2020, discussions between Endeavour and SEMAFO recommenced. Endeavour’s management team completed on-site due diligence at SEMAFO’s operations in Burkina Faso during February 2020, including a comprehensive assessment of security, operations and exploration.

Both companies also re-opened data rooms for mutual confirmatory due diligence, including visits and, following collaborative discussions, confirmed their shared strategic vision and desire to complete a combination subject to negotiation of agreeable terms, they said. Negotiations proceeded, culminating in agreement on the terms of the transaction announced today.

For Endeavour, pursuant to the rules of the TSX, the transaction will require approval by a simple majority of the votes cast by its shareholders. In addition, shareholders of Endeavour will be asked to approve the issuance of Endeavour ordinary shares to La Mancha. For SEMAFO, meanwhile, the transaction will require the approval of 66.6% of votes cast by its shareholders.

It is anticipated that both shareholder meetings and the closing of the transaction will take place in the June quarter of 2020.

The World Gold Council has welcomed Teranga Gold Corp and Endeavour Mining Corporation as its newest board members.

David Harquail (pictured), Chair of the market development organisation for the gold industry, said: “Both companies play an important role in the production and exploration of gold across West Africa and bring with them a wealth of experience that will be of significant value.”

Teranga is a Canada-based gold company focused on production and development as well as the exploration of approximately 6,000 km2 of land located on prospective gold belts across West Africa, according to the WGC.

Since its initial public offering in 2010, Teranga has produced more than 1.6 Moz of gold at its flagship operation in Senegal. Focused on diversification and growth, the company is advancing construction of its second producing gold mine, located in Burkina Faso, as well as carrying out exploration programmes in Côte d’Ivoire, Burkina Faso and Senegal.

Endeavour is an intermediate gold producer with a track record of operational excellence, project development and exploration in the Birimian greenstone belt in West Africa, WGC said.

Endeavour operates four mines across Côte d’Ivoire (Agbaou and Ity) and Burkina Faso (Houndé, Karma) which are expected to produce 615-695,000 oz in 2019 at an all-in sustaining cost of $760-810/oz.

Sébastien De Montessus, CEO and President of Endeavour, said: “We are very pleased to be joining the World Gold Council. We share the organisation’s belief in the importance of setting global standards to reinforce trust and transparency in the sector and across the whole value chain. We look forward to working with the council and its members to improve understanding of the gold industry.”

Richard Young, President and CEO, Teranga Gold, said: “For more than 30 years, the World Gold Council has supported greater understanding of gold’s enduring value and global influence. Today, at a time of both uncertainty and unprecedented opportunity, the work of organisations such as the World Gold Council is of paramount importance.”
