TSX-lsited Orezone Gold Corporation has signed a Power Purchase Agreement with Genser Energy Burkina for the supply of clean energy electrical power for its Bomboré gold project in Burkina Faso.
Genser will use liquefied natural gas (LNG) as its main fuel, augmented with a staged solar plant. The Bomboré project will be the first mine in Burkina Faso to use LNG to power its operations.
The power plant will consist of six 2.5MW LNG generators with four 2.6MW diesel back-up units. This configuration is sized for the initial oxide operation and the planned sulphide expansion. A Solar Photovoltaic Plant up to 14MWp to be installed in stages with an 11kV powerline to connect the gas and backup diesel generators, and solar plant.
Genser will design, permit, finance, and install all power generating equipment and associated infrastructure including LNG storage and diesel storage terminals.
The company will be the operator and owner of the power plant facility.
Patrick Downey, Orezone’s president and CEO stated, “We are extremely excited to be the first mine in Burkina Faso to use a LNG and solar hybrid power supply. Besides being an excellent cost-effective choice for Bomboré, we also see this new power solution as being a very positive step for the Burkina Faso mining and electricity generating sectors. LNG power systems, coupled with solar, will enable energy intensive industries such as mining to reduce fuel consumption, decrease energy costs, and significantly cut greenhouse gas emissions.”
First gold pour remains on track
Meanwhile, Orezone has reported that significant progress has been made at Bomboré during Q1 and Q2 of 2021. Engineering is now approximately 30% complete and on schedule. Design and bulk quantities from this work are trending favourably against the quantity estimates used in the 2019 feasibility study.
In addition, procurement is well-advanced with firm orders placed for most mechanical and electrical equipment with purchase costs generally below budget estimates.
Bulk materials including concrete reinforcing bar and embeds, CIL tank platework, structural steel and platework, HDPE liner, and overland piping have also been ordered with costs also trending within budget.
Off-channel reservoir mining, earthworks for the plant site area and tailings storage facility are rapidly advancing, and the award of the contracts for concrete installation and CIL tank erection and overland piping are imminent. The project remains on track for first gold pour in Q3 2022.
