Poseidon Nickel (ASX: POS) (“Poseidon” or “the Company”) is pleased to report an updated Mineral Resource Estimate (MRE) for the Black Swan disseminated sulphide deposit at Black Swan.
Key Points
- Updated Black Swan Disseminated Mineral Resource Estimate reported as follows:
- 28.9Mt at 0.63% nickel containing 181kt nickel at a 0.4% cut off; including
- Measured and Indicated Resources of 10.7 Mt at 0.75% nickel containing 80kt nickel
- Measured and Indicated Resources now have 35% more contained nickel compared to the 2014 Resource
- Global Resource nickel inventory has increased by ~10kt contained nickel and is at a higher average grade
- The updated Black Swan Mineral Resource has significantly improved the confidence in the nickel grade and distribution of the metallurgically important serpentinite and talc-carbonated hosted disseminated mineralisation immediately below the Black Swan open pit
- The update Resource underpins the previously outlined “Fill the Mill” Strategy
Managing Director and CEO, Peter Harold, commented, “The update of the Black Swan Disseminated Resource is an important milestone for our Fill the Mill Strategy. Black Swan has a 2.2Mtpa process plant (mill) and our strategy is to “Fill the Mill” to leverage off the existing infrastructure and large resource base at Black Swan.
The latest MRE incorporates the results from the recent underground drill programs undertaken from the Gosling drill drive. We are pleased the update has resulted in both an increase in the overall tonnes of contained nickel together with an increase in the inventory of the Measured and Indicated Resources. Most importantly, the recent drilling has provided an improved understanding of the disseminated grade distribution within the metallurgically important serpentinite and talc-carbonate hosted ores below the existing Black Swan open pit. The improved metallurgical understanding is key to further de-risking the restart of Black Swan.
Work is well advanced on optimising the pit shell designs from the new MRE and from the underground mining studies at Silver Swan and Golden Swan. Once completed, this work will allow the updating of Ore Reserves for the Black Swan Project to underpin the Bankable Feasibility Study.”
The MRE was prepared for Poseidon by independent resource consultants Golder Associates Pty Ltd (Golder) using all available assay data as at June 2022. The updated MRE now totals 28.9 Mt @ 0.63% Ni for 181kt of nickel metal contained. The MRE replaces the previous Black Swan MRE completed by Golder in 2014 (refer to Company announcement “Black Swan Mineral Resource” dated 4 August 2014) which reported 29.1 Mt @ 0.59% Ni for 170.9kt of nickel metal contained excluding stockpiles which have not been updated at this time.
TABLE 1 - COMPARISON BETWEEN 2014 MRE AND 2022 MRE AT 0.4% NI CUT-OFF
The updated 2022 Black Swan MRE is classified in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC 2012) and are reported herein above a 0.4% Ni cut-off grade in Tables 1 and 2. The JORC 2012 Compliance tables (Sections 1, 2 and 3) that accompany this announcement are contained in Appendix 1.
Competent Persons for this updated 2022 MRE are Poseidon’s in-house geology team for providing the validated drill hole database and the lithological and mineralisation domains for the Black Swan deposit. Golder’s personnel were responsible for the estimation, reporting and classification of the MRE.
New Data
The updated MRE incorporates 5,144 metres of new drilling from 24 diamond drill holes (DDH) completed by Poseidon between October 2021 and March 2022 (refer to Table 2 and Appendix 2) and 14 RC holes (2,481 metres) completed in 2019 (refer to Company announcement “Black Swan underground RC Drilling – Final Assay Results” dated 27 November 2019). Both drill programs were completed from underground using the Gosling access drive. The recent 24-hole drill program was specifically undertaken to increase the confidence in the Black Swan MRE, by infilling the area extending approximately 125 metres immediately below the existing Black Swan open pit with the objective of better delineating the metallurgically important serpentinite and talccarbonate hosted resources in this area. Below this area, the MRE is based on the same historical drill hole data that was used in the August 2014 MRE.

Key Project
Kremer Project
The 100 percent owned Kremer project is Ni-Co Energy’s flagship exploration asset and a prime example of the company’s focus on uncovering critical mineral resources within geologically favorable but underexplored regions. Located approximately 90 kilometers from downtown Montreal and about 15 km northwest of Saint-Côme, the Kremer property enjoys excellent accessibility and infrastructure — a significant advantage for an early-stage exploration project.
The project comprises 233 mining claims covering 15,375 hectares, within the Grenville geological province, an area known for its potential to host nickel-copper-cobalt magmatic sulfide systems, particularly along the margins of a large anorthosite intrusion. The property benefits from its proximity to paved highways, well-maintained logging roads, powerlines and skilled labor pools. These logistical advantages significantly reduce exploration costs and timelines while positioning the project favorably for future development and potential production scenarios.
Geological Characteristics and Exploration History
The property is underlain primarily by paragneiss rocks of the Grenville province and lies near the Morin Anorthosite Complex, a large intrusive body known to host iron-titanium-vanadium and nickel-copper-cobalt mineralization. Historical grab samples from around the “Lac à la Mélasse” area have returned values up to 3,547 parts per million (ppm) nickel, 1,107 ppm copper, and 924 ppm cobalt, supporting the district's critical mineral potential
In 2021 and 2022, Ni-Co Energy completed airborne magnetic and time-domain electromagnetic (TDEM) surveys, covering 1,659 line-kilometers. These surveys identified numerous EM conductors, particularly concentrated in the northwestern sector of the property. A ground gravity survey conducted in 2024 detected multiple weak to moderate positive anomalies, suggesting the presence of sulfide-rich bodies or lenses that could host nickel-copper-cobalt mineralization.
The company’s 2023 maiden diamond drilling campaign included 22 drill holes totaling 4,201 meters. Of these, a significant proportion intersected massive (>50 percent) and semi-massive (<50 percent) sulfide mineralization. Highlights include:
- DDH 20-2023: 1.73 percent nickel, 0.85 percent copper over 2.95 meters
- DDH 04-2023: 1.58 percent nickel, 0.42 percent copper over 2.70 meters
- DDH 21-2023: 1.46 percent nickel, 0.71 percent copper over 1.80 meters
Advancements and Future Prospects
In 2024, Ni-Co Energy deployed a suite of advanced geophysical tools, including drone-based magnetics, ground gravimetric surveys, and borehole TDEM, to sharpen its geological targeting. These efforts identified two major mineralized zones:
Northwest Zone: This drilled zone features continuous surface mineralization extending over 700 meters, exposed every 25 to 50 meters, with blown trenching done at two places up to 1 meter deep to verify mineral continuity.
Southeast Zone: A newly uncovered area approximately 7 km from the current drilling site, exhibiting fresh nickel-copper-cobalt mineralization indices and offering substantial exploration upside.
Ground EM, MAG and gravity surveys are overlapping in the central 3-km long zone. This highly prospective area is believed to host a mafic intrusion buried at shallow depth and will be drill tested during the 2025 program. Ni-Co Energy also intends to do some step-out drilling in the already drilled northwest zone to confirm mineralization extent.
With infrastructure in place and geophysical indicators pointing to scale, the Kremer project offers a compelling combination of accessibility, geological potential and alignment with critical mineral supply priorities.
For 2025, Ni-Co Energy plans to implement a two-phase exploration program with a combined budget of over C$2 million. The programs includes follow-up drilling based on overlapping structural, geophysical, and geochemical anomalies
