Orea Completes Montagne d’Or Gold Project Modifications
Vancouver, BC, Canada, December 22, 2020, Orea Mining Corp. (“Orea” or the “Company”) (OREA: TSX) (OREAF: OTCQX) (3CG: FRA) is pleased to announce the completion of additional engineering and environmental studies for the development of the Montagne d’Or gold mine in French Guiana, France.
“This is a major milestone for permitting of Montagne d’Or, one of the top undeveloped gold deposits in the Guiana Shield” commented Rock Lefrançois, President & CEO of Orea.
The Montagne d’Or joint-venture (owned 44.99% by Orea and 55.01% by Nord Gold SE) launched additional engineering and environmental studies in early 2019 for project modifications and improvements subsequent to the bankable feasibility study completed in 2017 and public consultation held in 2018. The studies principally addressed mine design, access road layout, hybrid on-site power generation and quarry development for construction material. They also included additional fauna and flora inventories, geotechnical drilling, ground geophysical surveys, geochemical analysis and laboratory test work.
The complementary studies, which involved a number of international and French and local consulting firms, are now substantially complete with final fauna and flora surveys over the selected Natural Compensation Site to be conducted in February 2021. The current schedule is to have all draft versions of the permitting dossiers to be completed by the end of December 2020 with final versions to be produced in the first quarter of 2021.
The principal components of the completed studies include:
- Tailings storage facility redesign, lowering the height of retainment dams and dam break study;
- On-site hybrid solar power generation, eliminating the environmental impacts of connecting the mine to the local power grid, which involved the construction of a 106-km aerial power line, reducing the overall carbon emissions of the project by 80%;
- Waste management plan and waste rock storage redesign to avoid acid drainage;
- Hydrogeological modelling, detailed water management, water balance and contact water pond design;
- Quarry development for construction material and multi-criterion comparative analysis of the studied quarry site alternatives;
- Detailed redesign of the 125 km access road from Saint-Laurent du Maroni, stormwater and safety devices, bridges, watercourse crossings, retaining walls and rehabilitation of abandoned sections;
- Hazardous material transport study and supply, transport and storage of explosives;
- Overall project mass balance and site closure and rehabilitation plan; and
- Natural Compensation Site development.
About Montagne d’Or
Montagne d’Or is a permitting-stage open pit gold deposit that hosts Measured Mineral Resources of 10.3 Mt at 1.804 g/t (600,000 oz), Indicated Mineral Resources of 74.8 Mt at 1.350 g/t (3.25 Moz) and additional Inferred Mineral Resources of 20.2 Mt at 1.48 g/t gold (960,000 oz), prepared in accordance with the requirements of National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). The Mineral Resources are confined within a pit shell defined by a gold price of US$1,300/oz and a cut-off grade of 0.4 grams per tonne gold. Mineral Reserves have also been defined with Proven Mineral Reserves of 8.25 Mt at 1.99 g/t (530,000 oz) and Probable Mineral Reserves of 45.87 Mt at 1.50 g/t (2.2 Moz). The Proven and Probable Mineral Reserves were estimated using a gold price of US$1,200 per ounce at varied cut-off grades from 0.552 to 0.665 grams per tonne gold, dependent on lithological rock types, economics and estimated metallurgical recovery. Montagne d’Or ore can be readily processed to recover the contained gold and silver values using unit operations considered standard to the industry. It is a large and unique Paleoproterozoic gold-rich volcanogenic sulfide deposit, presently drill-defined over a strike extent of 2,300 meters and to a vertical depth of 200 to 250 meters.
Montagne d’Or is located in northwestern French Guiana, 180 kilometers west of the capital Cayenne and is accessed by 125 kilometers of laterite road from the commune of Saint-Laurent du Maroni, the second largest city in French Guiana. Nordgold first earned a 50.01% interest in the project in September 2017 by spending US$30 million and completing a Bankable Feasibility Study (“BFS”). Nordgold then acquired an additional 5% interest pursuant to a share purchase agreement.
The 2017 BFS contemplates an open pit operation over a 12-year mine life. Highlights of the BFS at a gold price of US$1,250 per ounce are as follows:
- After-tax Net Present Value (NPV) at a 5% discount rate: US$370 million
- After-tax Internal Rate of Return (IRR): 18.7%
- After-tax payback period: 4.1 years
- Average annual gold production for years 1 to 10: 237,000 ounces
- Average gold grade for years 1 to 10: 1.73 grams per tonne gold
- All-In Sustaining Cost (AISC) for years 1 to 10: US$749 per ounce of gold
- Initial capital expenditures (after surplus tax credit): US$361 million
The BFS economic model gold price sensitivity shows that the after-tax project NPV at a 5% discount rate changes approximately US$1.24 million for every US$1 change in gold price. At a gold price of US$1,500 per ounce, the NPV and IRR increase respectively to US$681 million and 26.7%.
Upside Potential of Montagne d’Or
There are several opportunities to increase the current Mineral Reserves and mine life within the designed resource pit. Approximately 2 million ounces of Mineral Resources are not converted to Mineral Reserves, which include Inferred Mineral Resources of 960,000 ounces of gold at average grade of 1.48 grams per tonne gold. Infill drilling has the potential to convert some of these Inferred Mineral Resources to higher resource classification categories.
There is also the potential to lower the cut-off grade used for the Mineral Reserve estimates, in consideration of the current higher gold price, which could convert some additional Indicated Mineral Resources into Mineral Reserves.
Limited drilling has been carried-out outside the resource pit. The 2017 drilling program was successful in confirming gold mineralization up to 400 meters on strike to the west (0.56 g/t gold over 58.1 meters, including 2.32 g/t gold over 9.0 meters) and at depth, 100 meters below the resource pit (0.92 g/t Au over 41.2 meters, including 1.92 g/t Au over 17.7 meters) (see Orea’s news release dated August 15, 2017).
