Recently a Vietnam visit was conducted to coordinate parties to confirm DFS study progress and advance early engagement activities. The companies visited were:
- Narime – plant and non-process infrastructure engineering and design
- Early engagement of fabricators and construction contractors
- Scan Global Logistics – logistics study for both construction and operational phases
- Tedi Wecco – port engineering and design
- Hong Ha – access road upgrade and design
- Global Green Energy Consulting – power infrastructure engineering and design
- Vimluki – environmental impact assessment
- DRCC – social and economic baseline assessment
Narime continue to assist globally renowned Wood, acting as lead in-country engineering consultant, in the development of the Ta Khoa Refinery DFS. Narime bring a wealth of local knowledge and experience to the DFS, supporting Wood with design and local pricing. The quality of work from Narime has exceeded Wood’s and Blackstone’s expectations, allowing for a greater level of accuracy of engineering, thus reducing project risk and future engineering scope. Blackstone looks forward to future engagement with Narime to leverage off their innate local knowledge of construction, fabricators, material availability, labour rates, and project management techniques.
Blackstone has commenced early engagement of Vietnamese fabricators and contractors. In a recent site visit to Vietnam, the Blackstone team visited some of the largest fabrication companies and facilities in the world, each with a diverse client base ranging from thermal power plants, oil and gas, refining, cement and steel fabrication plants in Asia, Europe, the US, and Australia. A sample of their client base is given in Figure 2. All companies fabricate to international standards and are ISO accredited. Blackstone will continue to investigate in-country fabricators and constructors to ensure Vietnamese pricing is captured during the Ta Khoa Project procurement process.

Scan Global Logistics was selected to complete the logistics study for the DFS. Significant effort was placed in reviewing several options for both the construction and operational logistics phases of the Project. Figure 3 shows the proposed route from ocean port to site. International transport will be received at the Hai Phong port where it will be transported on major highways to the Hoa Binh Port. Material from this point will be barged on Da River between Hoa Binh to dedicated ports at the Ta Khoa Refinery and Ta Khoa Nickel mine sites. This route will maximise the flexibility of loads during construction and operation while limiting the requirement of road networks, thus reducing local community impact, and reducing CAPEX for road upgrades.

Investor Insights
Blackstone Minerals is well-positioned to leverage a projected nickel supply deficit as it strives to become a vertically integrated producer of low-cost, low-carbon, battery-grade nickel. Key to this is Blackstone’s Ta Khoa project in Vietnam, an emerging hub for the electric vehicle market.
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.
Blackstone Minerals business structure schematic
With over 20 active mines and a burgeoning technology sector, Vietnam is on the road to becoming a hub of electric vehicle production and innovation, with low labor costs and regulated electricity pricing further driving its growth. Steadily increasing foreign direct investment in the region is indicative of this as the country seeks to attract $50 billion in new foreign investment by 2030.
Blackstone is uniquely positioned to take advantage of this, thanks to two factors. US President Joe Biden's Inflation Reduction Act, which came into force in August 2022, represents the largest investment into climate action in United States history. A similar initiative is rolling out in the European Union (EU), which maintains a Free Trade Agreement with Vietnam — something multiple partners of the company have expressed interest in.
Blackstone's Ta Khoa Project consists of two streams, the Ta Khoa Nickel Mine and the Ta Khoa Refinery. Recent milestones point to Blackstone’s commitment to advancing this game-changing project.
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 December 2023, Blackstone entered into an option agreement with CaNickel Mining to acquire the Wabowden nickel projectlocated in the world-class Thompson Nickel Belt in Manitoba, Canada.
The Wabowden project will have the potential to fill the Ta Khoa Refinery, removing dependence on third party feed sources.
The company has signed a non-binding MOU with the Development for Resources Environmental Technology joint stock company (DRET) to investigate opportunities to repurpose and trade waste material (or residue) from the Ta Khoa Refinery into construction material products. Moreover, it has also progressed the Ta Khoa Refinery byproduct offtake strategy with Vietnam Chemical Group (VinaChem), PV Chemical and Equipment Corporation (PVChem) and Nam Phong Green Joint Stock Company (Nam Phong) to sell Ta Khoa Refinery byproducts, being manganese sulphate (or epsomite) and sodium sulphate.
As the company plans to build a global nickel business, Blackstone signed a non-binding memorandum of understanding with Yulho Co. Ltd (Yulho) and EN Plus Co. Ltd (EN Plus) to establish a collaboration across the businesses including EN Plus and Yulho who are in joint venture on the Ntaka Hill nickel sulphide project in Tanzania, and the Dinagat Island nickel laterite project in the Philippines.
Company Highlights
- The global nickel market is currently entering a structural deficit, with demand expected to grow 950 percent by 2040.
- Blackstone Minerals is well-positioned to address this deficit as a vertically integrated producer of low-cost, low-carbon nickel.
- Blackstone's flagship project Ta Khoa is a brownfield project situated in Vietnam, one of the lowest capital cost countries in the world and an emerging hub for the electric vehicle market with vast reserves of nickel.
- Vietnam is an increasingly attractive region for investment with direct foreign investments that grew from $1.3 billion in 2000 to $15.6 billion in 2020.
- The Ta Khoa project also has infrastructure advantages, via the existing Ban Phuc mine, and processing facilities, access to low-cost and underutilized hydroelectricity, a trained labor force and support from the local government.
- Blackstone Minerals’ downstream pre-feasibility study confirms a technically and economically robust hydrometallurgical refining process to upgrade nickel sulphide concentrate to produce battery-grade nickel.
- Blackstone’s key nickel and cobalt feedstocks for the Ta Khoa Refinery Pilot program were delivered to the metallurgical laboratory in Western Australia as of April 2022.
Key Project
Ta Khoa
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.
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.

Promising new source of low-carbon, battery-grade nickel
FPX Nickel Completes Production Run of Battery-Grade Nickel Sulphate to Support Discussions with Prospective EV Battery Supply Chain Partners
Overview
As described in the Company's October 15, 2024 news release, FPX completed a pilot-scale refining test program to advance the technical maturity of refining the Baptiste awaruite concentrate to nickel sulphate. This test program included continuous, pilot-scale leaching to produce low-impurity leach solution. A small portion of the leach solution was further advanced through purification and crystallization operations to nickel sulphate crystals to demonstrate the technical viability of the purification process. The remainder of leach solution was retained for future testing including continuous, pilot-scale processing of the purification and crystallization area, ensuring the final refinery strategy is supported by purification and crystallization requirements defined in collaboration with FPX Nickel's current and prospective downstream partners.
FPX recently re-engaged Sherritt Technologies Ltd. to conduct an additional nickel sulphate production run, building on Sherritt's successful completion of the previous pilot-scale refining test program. In the current testing campaign, a portion of this remaining leach solution has been processed to produce larger quantities of nickel sulphate crystals. As with previous testing campaigns, the quality of the produced nickel sulphate, presented in Table 1, meets the strict target specifications for battery applications. To further advance the produced qualification process, the nickel sulphate samples will be provided to prospective downstream partners to ensure the quality and suitability of the nickel sulphate for their battery manufacturing process. Figure 1 shows a portion of the nickel sulphate samples produced.

About the Baptiste Nickel Project
The Company's Baptiste Nickel Project represents a large-scale greenfield discovery of nickel mineralization in the form of a sulphur-free, nickel-iron mineral called awaruite (Ni3Fe) hosted in an ultramafic/ophiolite complex. The absence of sulphur and our ability to connect to the BC Hydro grid means that Baptiste has the potential to be one of the lowest carbon-intensive nickel producers in the world and will produce a very high-grade product that does not require any intermediate smelting or complex refining. The Baptiste mineral claims cover an area of 453 km2 west of Middle River and north of Trembleur Lake, in central British Columbia. In addition to the Baptiste Deposit itself, awaruite mineralization has been confirmed through drilling at several target areas within the same claims package, most notably at the Van Target which is located 6 km to the north of the Baptiste Deposit. Since 2010, approximately US$55 million has been spent on the exploration and development of Baptiste.
FPX has conducted mineral exploration activities to date subject to the conditions of agreements with First Nations and keyoh holders.
About FPX Nickel Corp.

Ni-Co Energy Set to Mobilize Critical Minerals Exploration just 90 km from Montreal
Bilingual Corporate Video introducing Ni-Co Energy Inc.
Summer Field Program Priorities (June–July)
- Targeted prospecting of southwest TDEM conductors (Kremer-2)
To verify the presence of outcropping massive or semi-massive sulfides. - Prospecting of northeast TDEM conductors (Kremer-1 2)
To assess the nature of EM anomalies and any associated metallic indicators. - Analysis of residual conductors in the eastern portion
To refine the global geophysical model ahead of final drill target placement.
Updated Interpretation of the 420 Assays from 2023
The 420 samples from the 22 holes drilled in fall 2023 have been recalculated in terms of nickel equivalent (NiEq %), using metal prices as of May 22, 2025 (Ni = $7.0375/lb, Cu = $4.6559/lb, Co = $15.286/lb).
Indicator | Updated Result |
Samples > 0.5 % NiEq | 134 (≈ 32%) |
Samples > 1.0 % NiEq | 70 (≈ 17%) |
Maximum grade | 3.89 % NiEq |
Average grade (all samples) | 0.48 % NiEq |
These data confirm the presence of significant mineralization, which may be associated with a mafic intrusion interpreted from geophysical surveys. Magnetic, gravity, and EM data show remarkable alignment over 8 km, suggesting a highly favorable environment in the central block (Kremer-2) over a 3 km section — an ideal structural setting for the formation of thicker sulfide lenses.
Next Steps – The Company Anticipates Undertaking a Drill Program in the Fall
- Validate the position and dip of key targets through surface work.
- Mobilize two drill rigs in the fall to test the central fold hinge and associated deep conductors.
- Carry out borehole EM (BHEM) surveys after each drill hole to visualize the extension of mineralized zones or detect off-hole conductors.
Photos of the team, outcrops, and trenches will be shared regularly on the company website, as well as on Facebook, LinkedIn, and X during the campaign.
