Overview
As the world moves closer to a sustainable net-zero future, the need for battery metals continues to mount and nickel may soon be among the metals to see a supply crunch. Though its roots are in the stainless steel sector, it's also a critical component of lithium-ion batteries.
Given that many nations are aiming to replace combustion vehicles with electric cars by 2030, the metal is already experiencing a massive spike in demand. Benchmark Minerals expects the need for battery-grade nickel will increase about 950 percent by 2040.
It's imperative to ramp up global nickel production but the resource sector, for its part, must do so with a much-reduced carbon footprint to influence the sustainability of the entire value chain. Blackstone Minerals (ASX:
BSX, OTC:BLSTF, FRA:B9S) recognizes this. As a vertically integrated producer of low-cost, low-carbon nickel, the company aims to become a leading source of low CO2 emission nickel sulphide. Its flagship Ta Khoa Project in Vietnam is representative of that goal.
These milestones include a memorandum of understanding with Cavico Laos Mining to collaborate in a number of areas associated with CLM’s nickel mine in Lao People's Democratic Republic and supply of nickel products for Blackstone’s Ta Khoa Refinery in Vietnam. Blackstone also partnered with Arca Climate Technologies to further investigate the carbon capture potential at the Ta Khoa Project through carbon mineralisation, and explore opportunities to utilise Arca’s carbon capture technologies within the project.
In a bid to collaborate on the supply of renewable wind energy to the Ta Khoa Project, Blackstone signed a direct power purchase agreement with Limes Renewables Energy.
Blackstone received AU$2.8 million as an advance from a research & development (R&D) lending fund backed by Asymmetric Innovation Finance and Fiftyone Capital. The advanced payment reflects the significant investment by Blackstone to develop the Ta Khoa Refinery process and Blackstone’s unique strategy to convert nickel concentrate blends into battery products in the form of precursor cathode active material (pCAM).
In addition to Ta Khoa, the company also maintains the Gold Bridge cobalt and gold project near Vancouver, Canada.
In December 2023, Blackstone entered into an option agreement with CaNickel Mining to acquire the
Wabowden nickel project located in the world-class Thompson Nickel Belt in Manitoba, Canada.
Blackstone holds a 90 percent interest in the Ta Khoa Nickel-Copper-PGE Project, located 160 kilometers west of Hanoi in the Son La Province of Vietnam. It includes an existing modern nickel mine built to Australian Standards, which is currently under care and maintenance. The Ban Phuc nickel mine successfully operated as a mechanized underground nickel mine from 2013 to 2016.
Blackstone intends to complement the existing mine through the installation of a large concentrator, refinery and precursor facility, supporting integrated on-site production of nickel, cobalt and manganese precursor products for the Asia-Pacific market. One of Blackstone's key Research and Development objectives with Ta Khoa is to develop a flowsheet that will support this production.
To fulfill this goal, Blackstone is focusing on a partnership model, collaborating with groups committed to sustainable mining. It is also working to minimize its carbon footprint and implement a vertically integrated supply chain.
In addition to the early development of the King Snake and Ban Chang Massive Sulphide deposits, Blackstone plans to produce crystal nickel and cobalt sulphide intermediate products. Staged development of the refinery, meanwhile, predicts an initial train capacity of 200,000 tonnes annually in the first year, with a planned expansion to 400,000 by the second.
The mine is expected to begin production in 2025 and then ramp up to 8 million tons per annum (Mtpa) of nickel sulphide by 2027. Pilot Plant testing and definitive feasibility studies are also underway. Five groups visited the project in 2022 as part of the partnership due diligence process, accompanied by meetings with government representatives, Austrade, Australian department of foreign affairs and trade, financial institutions and other important stakeholders
Project Highlights:
- Multiple Massive Sulphide Deposits: The Ta Khoa project features several incredibly promising deposits including King Snake (up to 4.3 percent nickel and 18.2 grams per ton (g/t) PGE), Sui Phong (2.95 meters @ 2.42 percent nickel, 0.52 percent copper, 0.06 percent cobalt and 0.05 g/t PGE), and Ban Chang. The project is also the site of the Ban Phuc nickel mine, which was operated from 2013 to 2016 by Asia Mineral Resources, along with several exploration targets that have yet to be tested.
- Experienced Leadership: Internally, Blackstone’s owners’ team brings over 50 years of experience in leadership roles at major nickel mines and refineries globally. This experience has been complemented by ALS Group, Wood, Future Battery Industries CRC, Curtin University and the Electric Mining Consortium.
- Large Reserve and Mining Inventory: The entirety of Ta Khoa is estimated to contain probable reserves of 48.7 Mt at 0.43 percent nickel for 210 kilotons (kt) of nickel and a mining inventory of 64.5 Mt at 0.41 percent nickel for 265 kt nickel. This excludes Ban Khoa and other developing prospects.
- A Long-lived Project: The Ta Khoa mine is expected to produce a yearly average of 18 kt of annual nickel concentrate over its ten-year lifespan. Blackstone believes the refinery can potentially extend its life past ten years.
- An Established Mining Operation: Existing infrastructure onsite includes a 450 ktpa Mill and mining camp. The mine will also benefit from a highly supportive community and favorable government legislation — Blackstone is committed to collaborating with community stakeholders in the project's development.
- Feed Flexibility: Ta Khoa's refinery will offer multiple feed options, including nickel concentrate, mixed hydroxide precipitate, nickel matte and black mass. This flexibility greatly improves the security and greatly reduces the risk of the project overall.
- Valued Partnerships: Blackstone is collaborating with multiple industry leaders and groups in the development of Ta Khoa
- Compelling Pre-feasibility Study: The financial outcomes of a base case pre-feasibility study on the project are promising. Based on a conservative NCM811 precursor price forecast, Ta Khoa displays an exceptional internal return rate on capital invested.
- Integrated Vertical Strategy: Blackstone is constructing both the Ta Khoa mine and refinery against a highly supportive ESG, macroeconomic and fiscal backdrop. This along with Ta Khoa's low capital intensity gives the company a significant advantage over competitors. Said low intensity is the result of multiple factors, including competitive labor costs, favorable regulations and low-cost renewable hydroelectric power.
- A Leader in Low Emissions: Independent assessments from Digbee, Minviro and Circulor, alongside an audit from the Nickel Institute, have confirmed that Ta Khoa will be the lowest-emitting flowsheet in the industry, at 9.8 kilograms of CO2 per kilogram of precursor with opportunities for even further reduction.
- Promising Pilots: With the support of ALS and process engineering partner Wood, Blackstone recently completed a 12-month programme of work that developed a scaled version of its concentrate to sulphate flowsheet. The refinery, which processed more than 9 tonnes of concentrate and MHP, successfully achieved battery-grade nickel sulphate of 99.95 percent, with a nickel recovery rate of 97 percent.
- Current Roadmap: Blackstone's next priority is to complete a series of definitive feasibility studies. Once those are complete, it will focus on fully integrating the mine into the electric vehicle consumer supply chain and finalizing its refining partnership structure.
