Archer Exploration Corp. Provides 2024 Winter Drilling Results at Grasset Nickel Project

Highlights

• Drill hole GR24-10A intersected the newly discovered H1X Zone at 400 metres below surface:

  • 2.67% Ni, 0.44% Cu, 2.32 g/t Pt-Pd over 2.90 metres

  • Including 4.08% Ni, 0.98% Cu, 4.57 g/t Pt-Pd over 0.85 metres

  • Within a larger zone grading 1.19% Ni, 0.17% Cu, 0.99 g/t Pt-Pd over 8.20 metres

• The H1X Discovery Zone, discovered in 2023, is a high-grade south-eastern extension of the H1 Zone, as seen by:

  • GR23-03 : 1.55% Ni, 0.18% Cu, 1.2 g/t Pt-Pd over 5.80 metres

  • GR23-07 : 2.97% Ni, 0.10% Cu, 4.1 g/t Pt-Pd over 0.44 metres

  • GR23-08 : 1.06% Ni, 0.14% Cu, 0.7 g/t Pt-Pd over 5.60 metres

"Today's assay results further reinforce our confidence in the presence of a robust mineralizing system that we can't fully appreciate yet," said Tom Meyer, President and Chief Executive Officer of Archer. "As our technical team persists in exploring and defining the boundaries of the Grasset Deposit, we remain highly encouraged from the successes of our fall and winter drilling campaigns. We are particularly enthusiastic about future drilling as we focus on the H1X Discovery Zone at depth and towards the southeast, an area devoid of any historical drilling or exploration along the Sunday Lake Fault."

Winter 2024 Drill Program

The 2024 Winter Program consisted of three diamond drill holes totaling 1,323 metres of drilling. The primary objective of the program was to test the new geophysical anomaly, N9, approximately two kilometres northeast of the Grasset Deposit and to further explore the high-grade H1X Discovery Zone.

H1X Discovery Zone Drilling Results

Holes GR23-07 and GR23-08, drilled in December 2023, confirmed the extension of mineralization in the H1X Zone to a depth of approximately 430 metres, approximately 100 metres below the discovery hole, GR23-03, which intersected 0.30 metres of massive sulphides at a depth of 330 metres. Hole GR24-10A intersected the H1X Zone 50 metres above and 50 metres southeast of hole GR23-08. The mineralized zone is located on the northern contact at the bottom of the main ultramafic sequence.

Hole GR24-10A intersected 2.67% Ni, 0.44% Cu, 2.32 g/t Pt-Pd over 2.90 metres, including a subinterval of 4.08% Ni, 0.98% Cu, 4.57 g/t Pt-Pd over 0.85 metres within a broader zone grading 1.19% Ni, 0.17% Cu, 0.99 g/t Pt-Pd over 8.20 metres. The mineralization is comprised of two zones of massive sulphides, (pyrrhotine and pentlandite) 0.25 and 0.35 cm thick, within a 2.90 metre section of net-texture mineralization. This is the first intersection demonstrating large, high-grade net-texture thickness within the H1X Zone.

Hole GR24-11 was targeting the up-dip extension of the trend defined through the intersections of holes GR23-08 and GR23-03. Unfortunately, due to strong deviation, the hole interested the H1 Horizon 50 metres west of the target and intersected 0.41% Ni over 0.70 metres. As with hole GR23-07, the bottom contact of the ultramafic was strongly sheared with a small zone of disseminated sulphides.

Holes GR23-03, GR23-08 and GR24-10A, which now define the newly discovered H1X Zone, clearly demonstrate the presence of a strong mineralizing system that remains open in all directions below 250 metres in the southeast portion of the H1 Horizon (Figure 1).

Grades and textures, observed at the bottom of the main ultramafic package, indicate the potential for recent intersections to be at the fringe of a new high-grade-hosting ultramafic conduit. All four drill holes in the H1X Discovery Zone intersected nickel grades higher than the Indicated Resources average grade of the H1 Horizon of 0.82% (Tables 1 and 2).

N9 Target Drilling

The N9 electromagnetic conductive plate (Figure 1) was interpreted from a high-power, large loop InfiniTEM-XL surface survey conducted in 2023. The N9 plate ranges from a depth of 300 to 700 metres and occupies an area of approximately 400 by 400 metres. The anomaly is located at the northern contact of an ultramafic sequence (interpreted from magnetic surveys) similar in nature to the H1 Zone.

Hole GR24-09 was designed to intersect the center of the conductive plate, at a depth of about 400 metres below surface. Due to technical difficulties, hole GR23-09 was unable to reach its target and following an unsuccessful attempt to wedge the hole a depth of 336 metres, the decision was made to abandon the hole and move the drill rig to the Grasset Deposit for continued drilling of the H1X Discovery Zone. Notwithstanding the technical challenges, the N9 target remains a priority as it presents very similar characteristics to the S6 plate (Figure 1) that overlays the H1X Discovery Zone.

Erratum

Archer would like to make a correction to a previously published assay result in the press release "Archer Exploration Extends Mineralization to Depth in H1 Discovery Zone of Grasset Nickel Project' dated January 17, 2024. An inversion of two sample tags at the lab produced an error in our database resulting in an incorrect assay for one sample. Following a thorough audit by ALS Laboratory, the Company has received final verification and a new assay certificate with the corrected results.

Previously reported on January 17, 2024:

Corrected assay as of March 22, 2024:

The Company's database and figures have been modified accordingly.

Director Resignation

The Company also wishes to report that Mr. Michael Konnert has resigned as a director of the Company, effective immediately, to focus on other professional commitments.

The Board of Directors wishes to thank Mr. Konnert for his contributions to the Company as a director and wish him the best in his future endeavours.

The Grasset Project

The Grasset Deposit, discovered in 2012 and located at the southern end of the Grasset Ultramafic Complex, comprises two subparallel, and sub-vertically dipping zones (H1 and H3 horizons) of disseminated to locally semi-massive sulphides mineralization. The H1 and H3 horizons each remain open at depth and along strike to the northwest.

In 2021, an updated mineral resource estimate, using a 2016 drilling cutoff, was completed with an Indicated Mineral Resource Estimate of 5.5 Mt grading 1.53% nickel equivalent ("NiEq") and an Inferred Mineral Resource Estimate of 217,000 tonnes grading 1.01% NiEq. For additional information regarding Archer's Grasset Project please refer to the Technical Report entitled "NI 43-101 Technical Report for the Grasset Property, Quebec, Canada" dated effective September 2, 2022, prepared by Carl Pelletier, P.Geo., available under Archer's profile on www.sedarplus.ca.

The vast majority of the Grasset Ultramafic Complex is underexplored and limited exploration prior to 2016 resulted in the discovery of several significant nickel sulphides showings along the entire 23-kilometre-long belt. Most notable is the GUC Central discovery, 7 kilometres northwest of the Grasset Deposit, which hosts a 950-metre-thick ultramafic sequence with several mineralized horizons of nickel sulphides and a best mineralized intercept of 4.14% Ni over 0.65 metres, within 7.58 metres of 1.05% Ni.

The Grasset Deposit is one of the largest nickel sulphides deposits in Canada's Abitibi region and the only North American nickel sulphides deposit, with an Indicated Mineral Resource Estimate of more than 50,000 contained tonnes of nickel and an average NiEq grade of over 1.5%, not controlled by a major mining company.

Quality Assurance and Quality Control

Archer implements high-quality industry-standard quality assurance and quality control ("QA/QC") procedures for its diamond drill programs. Archer's geologists insert alternating blanks and standards approximately one per every 10 samples collected. Moreover, a blank is added after logged, potentially high-grade mineralized zones with standards additionally inserted within such mineralized zones. Overall, blanks and standards account for approximately 12% of the samples submitted to the lab.

All samples are being assayed at ALS's Val d'Or laboratory where duplicates are inserted in the sample sequence at a rate of 1 in 40 samples sequence alternating with standards and blanks to result in a QA/QC insertion rate of about 1 in 10 samples. All drill core samples are analyzed using a 4-Acid digestion followed by 33 element ICP-AES analyses (ALS's Code ME-ICP61). Over limit Ni results are further analyzed by 4-Acid ore grade elements ICP-AES process (Code ICP-81 or ME-OG62). Analyses for Au, Pd and Pt are done using the ore grade ICP-AES procedure (Code PGM-ICP23). Gold only assays are performed with Au-ICP21 or AU-GRA21 if any visible gold. ALS is an accredited laboratory (SCC - CAN-P-1579 and CAN-P-4E ISO/IEC 17025) and is independent of the Company.
