Blackstone Minerals Limited (“Blackstone” or the “Company”) is pleased to announce that the results from an independent Life Cycle Assessment (LCA), conducted by LCA Practitioners Minviro (www.minviro.com), underpin our vision to develop an industry leading, low CO2 emission nickel sulphide project to supply into the growing lithium-ion battery industry. The results support ongoing partnership and funding efforts by validating the Ta Khoa Project (TKP) design as the route with the lowest life cycle CO2 emissions compared to emerging and existing NCM811 precursor cathode active material production routes.
Minviro, who are also responsible for the completion of Tesla’s LCA in their 2021 Impact Report (https://www.tesla.com/ns_videos/2021-tesla-impact-report.pdf) and other industry peers1, were appointed by Blackstone to conduct an LCA on the production of Nickel-Cobalt-Manganese (NCM) precursor cathode active material (pCAM) at TKP. The study, which was conducted according to the requirements of ISO-14040:2006 and ISO-14044:2006, used data from Pre-feasibility Studies (PFS) published for the downstream Ta Khoa Refinery Project (TKR) (refer ASX announcement 26 July 2021) and upstream Ta Khoa Nickel Project (TKN) (refer ASX announcement 28 February 2022).
The Ta Khoa LCA study confirmed a result of 9.8 kg CO2 eq. per kg pCAM from the Company’s TKP in Vietnam, which is substantially lower than existing production pathways in terms of Global Warming Potential (GWP), with known opportunities to reduce even further to 6.3kg CO2 eq. per kg pCAM (refer Figure 1).
Figure 1: Summary of LCA GWP Results (Scope 1, 2 and 3 GHG Emissions)
As part of the accreditation process, the LCA was subject to a third party review by a panel of three industry experts. Chaired by Dr Viktor Kouloumpis, the panel included a representative from the Nickel Institute´s Public Policy team and an independent nickel metallurgical consultant.
While the Base Case GWP result of 9.8 kg CO2 eq. per kg pCAM is an excellent result, Blackstone is targeting zero emissions, and is evaluating the following options to further reduce the Ta Khoa GWP.
Figure 2: Distribution of Scope 1, 2 and 3 Emissions
Hydropower
While Blackstone has access to low CO2 impact hydropower produced in Vietnam, the LCA process and global carbon accounting standards will not recognise this until Blackstone secures a Power Purchase Agreement (PPA) with a power supplier. Blackstone is currently working to secure a PPA for hydropower which will then credit Blackstone with a 2.4 kg CO2 eq. per kg pCAM reduction in GWP.
Cobalt Hydroxide
Cobalt Sulphate supply contributes 1.3kg CO2 eq. per kg pCAM and Blackstone is seeking other Cobalt Sulphate from alternative lower GWP suppliers. Much of the GWP associated with the cobalt sulphate feedstock is attributed to the sulphate refining stages. Blackstone is looking to secure a lower quality cobalt hydroxide product which will then be refined in the TKR. This could yield a reduction in GWP of 0.7kg CO2 eq. per kg pCAM.
Hydrogen Co-production
Blackstone continues to explore the option of producing TKR’s oxygen via electrolysis of water. This process would yield a green hydrogen by-product with the potential to reduce the GWP of 0.4 kg CO2 eq. per kg pCAM.
Other potential reduction measures under analysis but that are yet to be quantified include:
- Preference for low carbon footprint third party concentrate supply;
- Carbon mineralisation of dry stacked tailings;
- TKR direct CO2 emissions capture (potential for up to 1kg CO2 eq. per kg pCAM reduction);
- Further electrification of mining, concentrating and refining processes;
- Low carbon ammonium nitrate supply; and
- Carbon off-set projects.
Blackstone chose GWP as the primary focus of the LCA as this is the common standard to compare environmental impact. Other results summarised in the attached Minviro LCA summary report include the Project’s impact on land and water given the sensitivity of the region and immediate vicinity of the Project. The results of the study will be used to inform environmentally informed decision making in design, construction, inputs and processes.

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.
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 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.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 Projects
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.
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.
Gold Bridge
The Gold Bridge Project is located approximately 200 kilometers northwest of Vancouver, BC. It comprises 365 square kilometers of 100 percent Blackstone-owned mining claims located in the Cordilleran Terranes of BC. It includes several, high-grade hydrothermal gold, cobalt, nickel and copper deposits and targets the historic Little Gem and Jewel mines.
Project Highlights:
- Significant Potential: Blackstone's geological model for the Jewel mine suggests it may have a similar geological setting to the world-class Bou-Azzer primary cobalt district in Morocco. There is potential for multiple similar deposits throughout the project.
- Favorably Located Anomalies: Having completed an extensive maiden exploration program, Blackstone has identified multiple large-scale IP anomalies at Little Gem, Erebor, Jewel and Roxey.
- A Nascent Venture: Blackstone is currently actively seeking joint venture partners for the Gold Bridge project.

Deeper Drilling Discovers Substantially Thicker Mineralisation at Horden Lake; Corresponding DHEM Results Indicate Exciting Depth Continuity
Highlights
- Step-out drilling and DHEM results discover material resource growth potential at the Horden Lake deposit
- Step-out drilling delivers 32.1m @ 1.2% CuEq1, representing a substantially wider copper zone down plunge in HN-24-98
- 32.1m @ 1.2% CuEq (0.57% Cu, 0.19% Ni, 0.08g/t Au, 0.13g/t Pd) plus additional 0.04g/t Pt, 192ppm Co, 8.2g/t Ag from 264.3m. Includes 14.2m @ 1.79% CuEq from 275.9m.
- Deepest hole in this zone, 70-90m diagonally down-plunge from the two nearest historic holes.
- Strong down-hole electromagnetic (DHEM) plates project extensions of mineralisation at depth
- HN-24-98 plate indicates the highly conductive mineralised zone extends equally each way along strike, up-dip 170m, and is more responsive below the hole, extending 225m down-plunge.
- HN-24-96 stacked plates indicate the hole hit the edge of a strongly mineralised zone which sits deeper and to the north of the previously reported 17.1m @ 0.58% CuEq and 11.9m @ 1.39% CuEq.
- These first two plates link over 300m of strike extent which remains open down-plunge. Additional DHEM survey results pending.
- Shallow infill drilling delivers 33.8m @ 0.81% CuEq from 38m in HN-24-100
- Results again highlight the significant Au, Ag, PGM and Co by-products never previously assayed.
- Demonstrates continuity of the wide zone of shallow open-pittable copper mineralisation.
- Significant depth extension via drilling and DHEM in the southern zone
- The lesser-drilled southern zone now demonstrates potential to match or possibly exceed the central zone where economic resources extend to 550m (still open), 50-60% deeper than currently defined in the south.
- Only ~30% of the strike length has been drilled below 220m, yet this deeper area already hosts ~30% of the current JORC resource.
- Assays from 25 holes remain pending, including multiple step-out and DHEM results across zones of open mineralisation.
Managing Director, Mr Fairhall said:
“These results show clearly the tremendous potential for Horden Lake to deliver substantial exploration upside, with hole 98 showing the copper zone expanding at depth with one of the best intersections on the project.
Most excitingly, we couple this with very strong DHEM conductors indicating this mineralisation has continuity along strike and clearly extends at depth.
It is important to highlight that drilling has defined high grade mineralisation to over 550m in the central zone (and still open), and we now see no reason why the southern zone cannot achieve a similar, or possibly better, result. We have a significant amount of news-flow in the pipeline and we shall release further assays as they become available, along with downhole EM results where surveyed.”
Overview
Horden Lake is a copper dominant Cu-Ni-Au-PGM-Co Project located 131km north-northwest of Matagami, in Quebec Canada. The Project hosts an indicated and inferred mineral resource estimate of 28mt at 1.5% CuEq, as a result of over 52,464m of drilling already completed on the property. Pivotal has recently completed a 7,097m / 34 hole diamond drilling campaign. 1,317m / 6 holes have been reported prior to this announcement.
The objectives of the drilling program were to infill missing by-product multi-element assay information, target resource expansion potential (which remains open at depth across its full extent) and collect a distribution of metallurgical sample for a complete test work program. Downhole EM surveys have also been completed to dimension future exploration potential and targeting.
The results of drilling in HN-24-98 together with HN-24-93 and HN-24-94, and DHEM across HN24-98 and HN-24- 96 provide strong evidence of substantial resource growth potential at depth. This southern portion of the deposit has only a couple of holes below ~200m vertical depth. In the central portion, drilling has defined continuous zone of resources to approximately 550m.
Figure 1: Drill plan map with significant 2024 results, Horden Lake Cu-Ni-Au-PGM Project
Drill Hole and DHEM Discussion
Reported results are focused in the southern portion of the Horden Lake deposit. Hole HN-24-98 was designed to test step out potential, whilst holes HN-24-99 and HN-24-100 were shallower holes designed to infill continuity and collect by-product assay information not taken previously. DHEM survey results for HN-24-98 are also reported here, along with the survey results of HN-24-96 (assays reported on 10 June 2024).

First Two Step-out Holes Extend High Grades at Horden Lake
Highlights
- High grade copper mineralisation extended down-plunge in hole HN-24-97, the first step-out hole reported from the 2024 drill program.
- 21.5m @ 0.98% CuEq1 (0.56% Cu, 0.12% Ni, 0.07g/t Au, 0.09g/t Pd) plus additional 0.03g/t Pt, 119ppm Co, 8.3g/t Ag from 266.1m
Including 7.2m @ 1.56% CuEq from 280.4m - Deepest hole in this zone, 80-110m diagonally down-plunge from the two nearest historic holes
- 21.5m @ 0.98% CuEq1 (0.56% Cu, 0.12% Ni, 0.07g/t Au, 0.09g/t Pd) plus additional 0.03g/t Pt, 119ppm Co, 8.3g/t Ag from 266.1m
- HN-24-96 extends downwards and infills high grade mineralisation in 130m gap between previously drilled holes.
- 17.1m @ 0.58% CuEq (0.25% Cu, 0.1% Ni, 0.03g/t Au, 0.06g/t Pd) plus additional 0.03g/t Pt, 95ppm Co, 3.9g/t Ag from 203m
Including 5.1m @ 0.95% CuEq from 206.6m - 11.9m @ 1.39% CuEq (0.42% Cu, 0.33% Ni, 0.03g/t Au, 0.13g/t Pd) plus additional 0.04g/t Pt, 230ppm Co, 4.8g/t Ag from 229.7m.
Including 7.8m @ 2.1% CuEq from 229.7m
- 17.1m @ 0.58% CuEq (0.25% Cu, 0.1% Ni, 0.03g/t Au, 0.06g/t Pd) plus additional 0.03g/t Pt, 95ppm Co, 3.9g/t Ag from 203m
- Mineralisation now defined to 200-230m vertical depth in the vicinity of these holes. This is less than half the ~550m depth that mineralisation has been defined to in the central part of Horden Lake.
- Significant gold, silver, palladium, platinum and cobalt metals delineated once again, which were not assayed in this part of the deposit during previous drill campaigns.
- Consistent news-flow ahead, including results from the remaining 5,780m / 28 diamond drill holes and downhole EM surveys to be released, followed by a mineral resource update and metallurgical test-work in H2.
Managing Director, Mr Fairhall said:
“Down plunge extensions are a key pillar of the significant upside story at Horden Lake. The southern flank of the deposit has only been drilled to around 200m, whereas mineralisation is defined to ~550m in the central portion. These high grade results in the south demonstrate the strong potential for resource growth at depth, with the deposit remaining completely open across its full strike extent. In addition, we anticipate increasing the metal content of the resource through inclusion of the significant palladium, gold, cobalt, platinum and silver assays we are seeing which were never before assayed for in this portion of the deposit.
We have a significant amount of news-flow in the pipeline as we release further assays and the results of downhole surveys as they become available.”
Overview
Horden Lake is a copper dominant Cu-Ni-Au-PGM-Co Project located 131km north-northwest of Matagami, in Quebec Canada. The Project hosts an indicated and inferred mineral resource estimate of 28mt at 1.5% CuEq, as a result of over 52,464m of drilling already completed on the property. Pivotal has recently completed a 7,097m / 34 hole diamond drilling campaign. 705m / 4 holes have been reported prior to this announcement.
The objectives of the drilling program were to infill missing by-product multi-element assay information, target resource expansion potential (which remains open at depth across its full extent) and collect a distribution of metallurgical sample for a complete test work program. Downhole EM surveys have also been completed to dimension future exploration potential and targeting.

Drill Hole Discussion
Holes HN-24-96 and HN-24-97 were designed to test step out and infill the deeper extensions in the southern portion of the Horden Lake deposit. Table 1 contains the significant intersections, and Figure 2 is a longitudinal section showing the spatial distribution of historical and new drill hole pierce points.
Table 1: Significant intersections. Lower cut 0.3% CuEq over 1.5m (max dilution 5m). Higher cut 1.1% CuEq over 1.5m (5m max dilution).
Figure 2: Longitudinal section looking southeast through the Horden Lake deposit
Hole HN-24-97 is located 140m down-plunge from the 2024 hole HN-24-95 (refer ASX announcement 16 May 2024), and 80m and 110m respectively diagonally down-plunge from holes previously drilled holes H25315 and H26812. Mineralisation falls within one wide intersection of 21.45m grading 0.98% CuEq (0.56% Cu, 0.12% Ni) from 266.1m (Figure 3). Higher grade intersections include 7.17m grading 1.56% CuEq (1.10% Cu, 0.13% Ni) from 280.38m, which includes 4.53m grading 2.05% CuEq (1.48% Cu, 0.18% Ni) from 282.15m. Mineralisation between 266.1 to 282.85 occurs within meta-pyroxenites, meta-gabbros, and mafic dykes and one semi massive sulphide zone. The highest grade zone, 282.85 to 287.55 m occurs within the metasediments with one massive sulphide mineralisation and included a single assay of 4.08% copper over 0.66m at 282.85m. Whilst an inferred zone of mineralisation above 0.3% CuEq was interpreted in this zone, no higher grade zone extended to this area and this intersection shows very encouraging extensions of high grade mineralisation at depth.
