Blackstone Minerals Quarterly Report for the Period Ending 31 March 2021

Ta Khoa Nickel – Copper – PGE Project

Upstream Business Unit (UBU)

• Multiple drill rigs active focussed on resource definition drilling and exploration for disseminated sulfide (DSS) and massive sulfide vein (MSV) prospects at the Ta Khoa Nickel – Copper – PGE Project in northern Vietnam
• Total of 14,502 metres of core drilling was completed in the March quarter, of which 5,285 metres were infill drilling at the large Ban Phuc DSS open pit orebody
• Infill drilling continued at the Ban Chang MSV prospect to support resource estimations and preliminary mining studies which are ongoing
• Testing of Electro-magnetic (EM) geophysics targets confirmed additional high grade MSV potential at the King Snake and Ta Cuong prospects:
• At King Snake high-grade massive sulfide nickel, copper and platinum group elements (PGEs) were confirmed (refer to ASX announcements dated 4 February 2021, 16 February 2021 and 11 March 2021); and
• At Ta Cuong significant sulfide mineralisation was identified in new Taipan Discovery Zone (TDZ), where drill hole TC21-03 intersected 39.70m of sulfide mineralisation including DSS, semi-massive sulfide (SMSV) and MSV (refer ASX announcement 25 February 2021)

Downstream Business Unit (DBU)

• The Company confirmed that separate Pre-Feasibility Studies (PFS) will be delivered for its Upstream and Downstream business units
• The Downstream PFS is anticipated to be completed by June/July 2021 and will consider expanded downstream refining capacity, which has potential to transform Blackstone into a globally significant Class 1 nickel producer
• Feedstock, namely nickel in concentrate, for the expanded planned refining capacity is expected to include both third – party concentrate and Blackstone’s potential orebodies within the Ta Khoa district in Northern Vietnam

Blackstone Minerals Limited (ASX:BSX) expanded downstream refinery is driven by strong indicative demand for the Company’s planned downstream products which will include Nickel:Cobalt:Manganese (NCM) precursor products suitable for the Lithium-ion battery industry, for example NCM811

• Blackstone intends to collaborate with Tier 1 partners to unlock the value of its expanded downstream refinery strategy, including EcoPro who are the world’s second largest manufacturer of cathodes and a major shareholder of Blackstone.

Corporate
• Letter of Interest signed with global commodity trading group Trafigura as part of its downstream refining strategy
• Highly-experienced hydrometallurgical engineer Tony Tang appointed General Manager Project Development – Downstream
• Blackstone to spin out non-core gold assets into new Codrus Minerals Limited IPO
• Blackstone commences trading on the US-based OTCQX Best Market
• Cash balance as at 31 March 2021 of A$19.2m

Blackstone Minerals’ Managing Director Scott Williamson commented:

“The March 2021 quarter was transformative for Blackstone as plans to expand our downstream refinery capacity were outlined to the market. Executing on our planned expanded downstream refinery strategy will see the Company become a globally significant Class I nickel producer.”

“During the March 2021 quarter the company continued an aggressive drilling program, adding confidence to the existing resource base as well as successfully targeting new massive sulfide opportunities including the King Snake prospect. The Ta Khoa district remains largely untested and we are confident based on our existing resource, initial success at multiple MSV deposits and from future exploration success, that the Ta Khoa Nickel – CuPGE project will be a significant feedstock for our downstream refinery in Vietnam for many years to come”

“The formalisation of Blackstone’s relationship with Trafigura, one of the largest commodity traders in the world, was an important milestone for the March 2021 quarter. The ability for our downstream business to access third-party concentrate will be important to meet the burgeoning demand for nickel driven by rapid growth in the Lithium-ion battery industry. During the quarter Blackstone continued to collaborate with Trafigura and the Company looks forward to presenting outcomes of the PFS for its downstream refinery business in
June / July this year.”

ASX Cobalt Stocks: 4 Biggest Companies in 2025

After spending much of the last two years trending downwards, the cobalt price is spiking in 2025.

About 75 percent of global cobalt output comes from the Democratic Republic of Congo (DRC). While electric vehicle (EV) demand has remained positive, cobalt oversupply has weighed on markets and hurt efforts to build supply chains outside of the DRC.

However, the country banned exports of cobalt in February in an effort to increase the metal's falling price. By mid-March, cobalt had spiked to US$36,170 per tonne, up more than 65 percent from its record-low price of US$21,550 hit in late January.

Increasing electric vehicle (EV) and lithium-ion battery demand is expected to be supportive for key battery raw materials in the coming years. This means that as demand for EVs increases, so too will demand for cobalt — and, as one of the top four cobalt-producing countries in the world, Australia finds itself in a position to capitalise on this demand.

Cobalt Market Update: Q1 2025 in Review

Cobalt metal prices fell to a nine year low in February after another year of oversupply, but rebounded sharply after the Democratic Republic of Congo (DRC) instituted a four month export pause for the critical metal.

After starting the year at US$24,495 per metric ton, cobalt ended the three month period at US$34,040.40, a strong 39 percent increase from January’s value. The price spread between cobalt’s first quarter low of US$21,467.70 on January 29 and its Q1 high of US$36,262 on March 17 is even more impressive at 69 percent.

The drop to US$21,467.70 marked the battery metal's lowest level since February 2016.

Electra Secures Federal Support for North America’s Only Cobalt Sulfate Refinery

Electra Battery Materials (TSXV:ELBM,NASDAQ:ELBM) announced on March 21 that it has received a letter of intent from the Canadian government for C$20 million in proposed funding.

The money would support the construction and commissioning of North America’s first battery-grade cobalt refinery, a critical step toward strengthening the region’s electric vehicle (EV) supply chain.

The refinery, located in Temiskaming Shores, Ontario, is set to produce 6,500 metric tons of cobalt sulfate annually, enabling domestic production of up to 1 million EVs per year. According to Electra, it would be a key step in reducing North America's dependence on China, which currently refines approximately 90 percent of the world’s cobalt.

Top 5 Canadian Cobalt Stocks of 2025

Cobalt prices have been in a steady state of decline for much of the past few years as the market has remained constrained by excess supply and eroding demand.

The sluggish market conditions were attributed to reduced demand from the battery sector and oversupply of material. As a result, prices remained under pressure, with limited signs of improvement expected in the near term.

Cobalt prices continued to face many headwinds at the beginning of 2025. The multi-year supply glut and the growing transition to cobalt-free electric vehicle battery chemistries pulled the value of the battery metal down to US$21,550 per metric ton on February 10, a low not seen for more than a decade.

However, the world's leading cobalt producing country, the Democratic Republic of Congo (DRC) placed a four-month ban on cobalt exports on February 22 in an effort to boost prices. As the DRC is responsible for more than 70 percent of global cobalt production, this of course sent prices for the battery metal soaring to a yearly high of US$36,170 per metric ton as of March 17.
