First Atlantic Nickel Expands RPM Zone Awaruite Nickel-Alloy (Ni₃Fe) Discovery: 400-Meter Northern Extension Yields 1.47% Nickel Concentrate Over 351 Meters in DTR Metallurgical Recovery Testing

 

 

 

 

 

First Atlantic Nickel Corp. (TSX-V: FAN) (OTCQB: FANCF) (FSE: P21) is pleased to announce positive Davis Tube Recovery metallurgical test results from drill hole AN-24-05, the final hole completed during the Phase 1 drilling at the RPM Zone, part of its district scale Atlantic Nickel Project. Drill hole AN-24-05 returned a continuous interval of 351 meters averaging 1.47% nickel and 1.53% chromium in magnetic concentrate, with a mass pull of 8.21%. This corresponds to a magnetically recoverable nickel grade (DTR grade) of 0.12% over the 351 meter interval. Located approximately 400-meters north of the initial RPM discovery hole AN-24-02, this step out hole confirms that widespread disseminated, visible awaruite mineralization extends significantly northward toward Pipestone Pond.

 

Phase 2 drilling is currently underway, building on the success of Phase 1, which already defined a 400-meter by 500-meter area of awaruite nickel mineralization. All four holes drilled at the RPM Zone in Phase 1 intersected disseminated awaruite mineralization, returning consistent nickel grades and recoveries. Concentrate grades from these holes ranged from 1.32% to 1.47% nickel, with mass pulls between 8.21% and 9.53%. Notably, all drill holes ended in mineralization and remain open in all directions, indicating significant expansion potential. The consistent magnetic concentrate grades and mass pulls across the drilled area underscore the extensive nature of the awaruite nickel mineralization in the RPM Zone.

 

Highlights:

  • AN-24-05 Extends RPM Zone 400 Meters North, Confirming Continuity of Awaruite Mineralization: Drill hole AN-24-05, the fourth hole completed during the Phase 1 drill program at the RPM Zone, extends the drill-defined mineralization approximately 400 meters north of the initial discovery hole (AN-24-02). The results confirm the continuity of widespread disseminated awaruite nickel mineralization within the RPM Zone.
  • Metallurgical Testing of AN-24-05 Returns 1.47% Nickel Concentrate Over 351 Meters: Davis Tube Recovery (DTR) testing of the 351meter mineralized interval in AN-24-05 returned a nickel grade of 1.47% in magnetic concentrate, with a mass pull of 8.21%. This equates to a magnetically recoverable DTR nickel grade of 0.12%. The total nickel recovery was 50.26% from a head grade of 0.24% total nickel, highlighting the effectiveness of magnetic separation as a metallurgical process for upgrading awaruite nickel mineralization.
  • Phase 1 Drilling Expands Awaruite Nickel Discovery at RPM Zone: The Phase 1 drill program has delineated an initial mineralized zone measuring 400 x 500 meters. All four holes within the RPM Zone intersected significant awaruite nickel mineralization, returning consistently high DTR concentrate grades ranging from 1.32% to 1.47% nickel and mass pulls of 8.21% to 9.53%. These results yielded magnetically recoverable DTR nickel grades between 0.11% to 0.14%, establishing a strong foundation for Phase 2 expansion drilling.
  • RPM Zone Discovery Highlights District-Scale Potential of Atlantic Nickel Project: The RPM Zone discovery occurs within a 30 km long, highly magnetic ultramafic nickel belt known as the Pipestone Ophiolite Complex. The zone is located approximately 25 kilometers south of historic awaruite nickel-alloy (Ni₃Fe) mineralization identified by Altius Resources and Cliffs Natural Resources in 2010 at the Atlantic Lake Zone. Average DTR nickel grades of 0.11% to 0.14% from the RPM Zone demonstrate the potential for district-scale awaruite mineralization within multiple target areas of the project.
  • Phase 2 Exploration and Expansion Drilling Underway to Expand RPM Mineralized Footprint: The Phase 2 drilling campaign is currently underway, utilizing a systematic grid-based drill plan designed to step out from the Phase 1 footprint. The program aims to expand the RPM Zone’s mineralized area and further define the extent of awaruite nickel mineralization.

The Company’s final drill hole from the Phase 1 program at the RPM zone, AN-24-05, has returned positive DTR metallurgical test results that extend the known awaruite mineralization approximately 400 meters to the north of the initial RPM Zone discovery hole (AN-24-02). Drill hole AN-24-05 intersected 351 meters of awaruite mineralization averaging 1.47% nickel and 1.53% chromium in magnetic concentrate. The interval demonstrated a consistent mass pull averaging 8.21% and a DTR nickel grade of 0.12%, with total nickel recovery averaging 50.26% over the 351meter interval. These results highlight the strong and uniform metallurgical properties of the northern extension of the RPM Zone.

 

With the completion of AN-24-05, Phase 1 drilling has delineated an initial mineralized footprint measuring approximately 400-meters by 500-meters. All four holes from the program successfully intersected broad zones of disseminated awaruite-bearing nickel mineralization. The metallurgical results are notably consistent across all holes, indicating uniform nickel alloy mineralization hosted within ultramafic host rocks and strong lateral continuity of the mineralization system, which remains open in all directions and at depth. Across the RPM Zone, Phase 1 drilling returned magnetic concentrate grades ranging from 1.32% to 1.47% nickel, with mass pulls between 8.21% and 9.53%. Corresponding DTR nickel grades averaged 0.11% to 0.14%, confirming the RPM Zone as an extensive awaruite-dominated nickel system with robust metallurgical characteristics. All Phase 1 holes ended in mineralization, providing a solid foundation for the Phase 2 drilling program, which aims to expand the mineralized footprint and further delineate the RPM Zone’s scale and continuity.

PHASE 2 DRILLING UNDERWAY TO EXPAND RPM ZONE MINERALIZATION

 

Phase 2 drilling is actively underway at the RPM Zone, with a program strategically designed to expand the current mineralized footprint beyond the approximately 400-meter length by 500-meter width area defined by the initial Phase 1 drill holes. Strategic step-out drilling at greater depths is now actively testing further expansion of mineralization in all directions – north toward Pipestone Pond, east toward Chrome Pond, and west into the RPM fault zone. Results from drill hole AN-24-05 highlight the strong potential for further expansion, with consistent DTR grades encountered throughout the hole, ending in mineralization. These findings indicate that the mineralized awaruite system extends further north, making the area towards Pipestone Pond a high-priority target.

 

The fully funded Phase 2 program is further supported by upgraded project infrastructure, including improved road access and expanded camp facilities. In addition, equipment optimizations have enabled deeper drilling capabilities, enhancing the Company’s ability to test the full vertical and lateral extent of the mineralized system. Together, these advancements position the Phase 2 campaign to meaningfully grow the RPM Zone’s known mineralized footprint across in all target directions.

 

Awaruite (Nickel-iron alloy Ni₂Fe, Ni₃Fe)

 

Awaruite, a naturally occurring sulfur-free nickel-iron alloy composed of Ni₃Fe or Ni₂Fe with approximately ~75% nickel content, offers a proven and environmentally safe solution to enhance the resilience and security of North America’s domestic critical minerals supply chain. Unlike conventional nickel sources, awaruite can be processed into high-grade concentrates exceeding 60% nickel content through magnetic processing and simple floatation without the need for smelting, roasting, or high-pressure acid leaching1. Beginning in 2025, the US Inflation Reduction Act’s (IRA) $7,500 electric vehicle (EV) tax credit mandates that eligible clean vehicles must not contain any critical minerals processed by foreign entities of concern (FEOC)2. These entities include Russia and China, which currently dominate the global nickel smelting industry. Awaruite’s smelter-free processing approach could potentially help North American electric vehicle manufacturers meet the IRA’s stringent critical mineral requirements and reduce dependence on FEOCs for nickel processing.

 

The U.S. Geological Survey (USGS) highlighted awaruite’s potential, stating, “The development of awaruite deposits in other parts of Canada may help alleviate any prolonged shortage of nickel concentrate. Awaruite, a natural iron-nickel alloy, is much easier to concentrate than pentlandite, the principal sulfide of nickel”3. Awaruite’s unique properties enable cleaner and safer processing compared to conventional sulfide and laterite nickel sources, which often involve smelting, roasting, or high-pressure acid leaching that can release toxic sulfur dioxide, generate hazardous waste, and lead to acid mine drainage. Awaruite’s simpler processing, facilitated by its amenability to magnetic processing and lack of sulfur, eliminates these harmful methods, reducing greenhouse gas emissions and risks associated with toxic chemical release, addressing concerns about the large carbon footprint and toxic emissions linked to nickel refining.

The development of awaruite resources is crucial, given China’s control in the global nickel market. Chinese companies refine and smelt 68% to 80% of the world’s nickel4 and control an estimated 84% of Indonesia’s nickel output, the largest worldwide supply5. Awaruite is a cleaner source of nickel that reduces dependence on foreign processing controlled by China, leading to a more secure and reliable supply for North America’s stainless steel and electric vehicle industries.

Analytical Method & QA/QC

 

Samples were split in half on site, with one half remaining in the core box for future reference and the other half securely packaged for laboratory analysis. The QA/QC protocol included the insertion of blanks, duplicates, and certified reference material (standards), with one QA/QC sample being inserted every 20 samples to monitor the precision and accuracy of the laboratory results. All analytical results successfully passed QA/QC screening at the laboratory, and all Company inserted standards and blanks returned results within acceptable limits.

 

Samples were submitted to Activation Laboratories Ltd. in Ancaster, Ontario, an ISO 17025 certified and accredited laboratory operating independently of First Atlantic. Each sample was crushed, with a 250 g sub-sample pulverized to 95% – 200 mesh. A magnetic separate was then generated by running the pulverized sub-sample through a magnetic separator which splits the sub-sample into magnetic and non-magnetic fractions. This involves running a 30 g split of the pulp through a Davis Tube magnetic separator as a slurry using a constant flow rate, a magnetic field strength of 3,500 Gauss, and a tube angle of 45 degrees to produce magnetic and non-magnetic fractions.

 

The magnetic fractions are collected, dried, weighed and the magnetic fraction is fused with a lithium metaborate/tetraborate flux and lithium bromide releasing agent and then analyzed on a wavelength dispersive XRF for multiple elements including nickel, cobalt, iron and chromium. The magnetically recovered nickel grade was then calculated by multiplying the XRF fusion nickel value by the weight of the magnetic fraction and dividing by the total recorded feed weight or magnetic mass pulled from the sample.

 

True widths are currently unknown. However, the nickel bearing ultramafic ophiolite and peridotite rocks being targeted and sampled in the Phase 1 drilling program at the Atlantic Nickel Project are mapped as several hundred meters to over 1 kilometer wide and approximately 30 kilometers long.
