Drilling Continues To Grow And De-Risk The World-Class Jaguar Nickel Sulphide Project

Latest step-out and deeper drilling at key deposits confirms the potential for further significant resource growth towards 1 million tonnes of contained nickel metal and beyond

Centaurus Metals (ASX Code: CTM, OTCQX: CTTZF), is pleased to advise that resource growth and development drilling at its 100%-owned Jaguar Nickel Sulphide Project in the Carajás Mineral Province of northern Brazil continues to deliver outstanding results. The latest results are expected to underpin further growth in the Mineral Resource while also continuing to de-risk the Project with positive in-fill drilling results.


  • Strong, high-grade results received from step-out drilling at the Onça Preta (OP) and Jaguar South (JS) deposits, with new assays including:
    • 42.7m at 0.98% Ni from 511.7m; including 4.1m at 2.42% Ni from 542.9m in JAG-DD-22-462 (OP)
    • 9.0m at 2.21% Ni from 599.0m in JAG-DD-22-460 (JS)
    • 24.4m at 0.82% Ni from 507.6m; including 4.2m at 1.58% Ni from 517.4m in JAG-DD-22-507 (OP)
    • 21.6m at 0.79% Ni from 511.4m in JAG-DD-22-464 (OP)
    • 11.0m at 1.43% Ni from 574.0m; including 3.0m at 2.49% Ni from 582.0m in JAG-DD-22-487 (JS)
    • 10.7m at 1.40% Ni from 478.0m; including 3.1m at 2.14% Ni from 478.0m in JAG-DD-22-515 (JS)
    • 7.5m at 1.78% Ni from 460.0m; including 5.5m at 2.19% Ni from 460.8m in JAG-DD-22-515 (JS)
    • 12.4m at 0.96% Ni from 605.4m; including 5.0m at 1.51% Ni from 607.6m in JAG-DD-22-462 (OP)
    • 8.5m at 1.40% Ni from 557.3m in JAG-DD-22-462 (OP)
  • Visuals and assay results from deeper drilling at Jaguar South confirm the continuity of high-grade mineralisation at depth, with excellent potential for further growth below the current Resource.
  • Further significant results received from completed in-pit in-fill drilling across all deposits, demonstrating the continuity of the mineralisation within the current Mineral Resource model. New assay results include:
    • 10.0m at 2.28% Ni from 105.0m; including 3.2m at 5.25% Ni from 109.9m in JAG-DD-22-404 (JC)

    • 21.5m at 0.66% Ni from 35.0m; including 4.1m at 1.66% Ni from 41.2m in JAG-DD-22-510 (JS)
  • The Jaguar November 2022 Mineral Resource Estimate (MRE), comprising 108.0Mt @ 0.87% Ni for 938,500 tonnes of contained nickel, is one of the largest nickel sulphide resources held by an ASX-listed company and the largest outside of the majors. A further MRE update is planned later this year.
Centaurus’ Managing Director, Mr Darren Gordon, said that the outstanding results received from resource growth and development drilling were consistent with the Company’s two-pronged strategy of continuing to grow and upgrade the Resource in parallel with key de-risking steps associated with in-fill drilling and the completion of the ongoing Definitive Feasibility.

“In November 2022 we updated our MRE to 108.0Mt @ 0.87% Ni for 938,500 tonnes of contained nickel, confirming Jaguar as one of the largest undeveloped nickel sulphide deposits globally. That Resource is already in the hands of the mining engineers and will underpin the DFS that will focus on a long-life project delivering +20,000tpa of nickel- in-sulphate for the rapidly growing global battery-EV industry.

“The development drilling that we are progressing continues to build confidence in the Resource in and around these open pits, and will also go a long way to continuing to de-risk the project beyond the DFS. At the same time, we will continue to grow the project in a systematic manner through targeted step-out and extensional drilling that is expected to push the resource beyond 1 million tonnes of contained nickel metal in 2023.

“Importantly, the recent deep drilling results from the Jaguar South and Onca Preta Deposits are well below the MRE limits and previous Scoping Study stope optimisations.

“Jaguar is shaping up as a Tier-1 supplier of nickel-in-sulphide and it is clear to us that the demand for nickel sulphate is growing rapidly as auto-makers increasingly focus on where they are going to source their nickel from and what the emissions footprint looks like for the nickel that is essential to their accelerating EV roll-out.”

Resource Growth – Step-out Drilling

The diamond rigs at Jaguar are now targeting resource growth by undertaking both step-out drilling and extensional drilling across all deposits, but with an initial focus on the high-grade Onça Preta and Jaguar South Deposits. These rigs will also continue to undertake important drilling for geotechnical, metallurgical and structural interpretation purposes.

The Company is in the process of optimising its contractor drill fleet, removing underperforming rigs and reducing the total number of rigs on site to six diamond rigs and one Reverse Circulation (RC) rig.

The May 2021 Jaguar Scoping Study demonstrated that both the Jaguar South and Onça Preta Deposits can sustain quality underground operations with the study stope optimisations bottoming out on the base of the January 2021 MRE.

The continual extension of the high-grade mineralisation, as demonstrated by recent drill results, both down-dip and now along strike at both deposits bodes well for continued resource growth and in turn future underground operations.

Jaguar South

The Jaguar South Deposit is the largest deposit at the Jaguar Project, hosting an MRE of 34.6Mt at 0.92% Ni for more than 316kt of contained nickel. The base of the November 2022 MRE continues to be constrained by the depth of drilling and ongoing step-out drilling continues to confirm that the mineralisation remains open at depth and along the +800m strike length of the deposit in both directions (see Figure 2 and Figure 3).

The deepest hole that the Company has completed to date on the Project, JAG-DD-22-4451 on section 478300mE, reached a final depth of 771m depth. Importantly, this hole successfully intersected a 10m thick zone of semi- massive and massive nickel sulphide mineralisation from 612m depth within a broader 20m intersection.

The intersection is 100m down-dip from the previously deepest hole on section JAG-DD-22-223 (16.4m at 1.34% Ni). Refer to Figure 1, Figure 11 and Table 2 for photos of the core and visual estimates of hole JAG-DD-22-445.

Drill-hole JAG-DD-22-487, the second deepest hole completed on the Project, was collared 90m to the east of JAG- DD-22-445 on section 478390mE and intersected 11.0m at 1.43 % Ni from 574.0m including 3.0m at 2.49% Ni amongst other intersections (Figure 2).

Blackstone Minerals Expands Portfolio with Mankayan Copper-Gold Project Acquisition

In a strategic move that marks a significant expansion beyond the company's nickel-mining operations, Blackstone Minerals (ASX:BSX,OTC Pink:BLSTF,FWB:B9S) has announced a merger of equals with IDM International to acquire the Mankayan copper-gold project in the Philippines.

This acquisition positions Blackstone to leverage its expertise in the evolving mining landscape, driven by energy transition requirements, according to Blackstone Managing Director Scott Williamson.

"We can leverage (the) experience that we have from operating in Vietnam, which is a similar jurisdiction. We've operated in Vietnam for the last five or six years; we've been focused on nickel in Vietnam. Now we can use that team and our expertise in developing mines in Vietnam to the Mankayan project in the Philippines," he explained.

The Mankayan project is renowned for its high-grade copper and gold potential, supported by impressive historical drill results. Williamson emphasized the project's significance, indicating the potential for a substantial resource expansion.

Nickel Price Forecast: Top Trends for Nickel in 2025

The nickel market has faced challenges over the past few years due to a supply glut and weak demand.

Even though the price of nickel surged in the first quarter of 2024, higher prices didn’t last. By the end of the year, any gains the base metal had made were erased, and it entered 2025 in the US$15,000 to US$15,200 per metric ton range.

What's in store for the rest of the year, and what nickel trends should investors be watching?
