ALASKA ENERGY METALS ANNOUNCES MAIDEN NI43-101 MINERAL RESOURCE ESTIMATE EXCEEDING 1.5 BILLION POUNDS OF CONTAINED NICKEL FOR THE NIKOLAI NICKEL PROJECT, ALASKA, USA
Mineral Resource Estimate - Inferred Mineral Resources
Eureka Zone East: 88.6 million tonnes grading 0.35% NiEq% containing: 471 million pounds of nickel 165 million pounds of copper 34 million pounds of cobalt 548,700 ounces of platinum, palladium, and gold
Eureka Zone West: 182.8 million tonnes grading 0.28% NiEq% containing: 1,080 million pounds of nickel 208 million pounds of copper 81 million pounds of cobalt 792,400 ounces of platinum, palladium, and gold
VANCOUVER, BRITISH COLUMBIA, November 20, 2023 – Alaska Energy Metals Corporation (TSX-V: AEMC, OTCQB: AKEMF) (“AEMC” or the “Company”) is pleased to announce the first independent National Instrument 43-101 Standards of Disclosure for Mineral Deposits (“NI 43-101”) mineral resource estimate (“MRE” or “2023 Resource”) for its 100% owned Nikolai Ni-Cu-Co-PGE-Au Project (“Nikolai Project”) in Alaska, USA. The study was completed by Stantec Consulting Services, Inc., utilizing historical drill hole data the Company purchased earlier in the year. The effective date of the MRE is November 20, 2023.
Alaska Energy Metals President & CEO Gregory Beischer commented: “The two areas in which we were able to calculate an inferred mineral resource, based only on historical drill holes, are approximately two kilometers apart. Other sparse, historical holes drilled between the deposits indicate a reasonable likelihood that further grid-based drilling will ultimately connect the two deposits together. The drilling we recently conducted in Summer 2023 will go part way towards joining the deposits together and is likely to further increase the contained metal in the deposits substantially. The rapid growth in resources speaks to the consistency and predictability of the deposit, which remains open in all directions. Eureka is quickly evolving into one of the larger nickel resources on the continent.”
The results of the 2023 Resource are reported below:
- Total Eureka Zone MRE contains an inferred mineral resource of 1.5 billion pounds of nickel, 372 million pounds of copper, and 115 million pounds of cobalt, plus a total of 1.34 million ounces of platinum, palladium, and gold in a constrained model totaling 319.6 million tonnes at an average grade of 0.30% total nickel equivalent (“NiEq”) using a 0.20% NiEq cut-off grade. See the detailed breakdown in Table 1 and Table 2 below.
- The Eureka Zone East MRE contains an inferred mineral resource of 471 million pounds of nickel, 165 million pounds of copper, 34 million pounds of cobalt, plus 549 kozs of platinum, palladium, and gold in a constrained model totaling 88.6 million tonnes at an average grade of 0.35% total NiEq using a 0.20% NiEq cut-off grade (Table 1 & 2).
- The Eureka Zone West MRE contains an inferred mineral resource of 1,081 million pounds of nickel, 208 million pounds of copper, 81 million pounds of cobalt, plus 792 kozs of platinum, palladium, and gold in a constrained model totaling 231 million tonnes at an average grade of 0.28% total NiEq using a 0.20% NiEq cut-off grade (Table 1 & 2).
- Deposits in the 2023 Resource are defined by 8 of 37 drill holes cored prior to 2023. Several of the remaining drill holes provide early confirmation that the mineralization is interconnected across all three deposits (Figure 1). The deposits remain open in all directions.
- The Eureka Zone East and Eureka Zone West MRE are located approximately two kilometers away from each other (Figure 1).
- Received and pending assay results from the eight-hole 2023 drill campaign are not included in the 2023 Resource. These eight holes were completed as ~250 to 300meter (“m”) step-outs to build outward from the 2023 Resource for the Eureka East, Eureka Zone 2 (“EZ2”) deposit (Figure 1). An updated NI 43-101 Mineral Resource Estimate is anticipated to be completed in 2024 with the additional drill results.
- Chrome and Iron are also present within the deposits but have not been reported in the 2023 Resource due to the lack of historical assay data and analytical methods used.
Mineral resources are not mineral reserves and do not have demonstrated economic viability. The 2023 Resource estimate will be incorporated into a NI43-101 compliant technical report for the Nikolai project to be filed within 45 days.

MINERAL RESOURCE ESTIMATION CALCULATION METHODOLOGY
The geologic model used for the reporting of mineral resources is a 3D block model, developed using Hexagon Mining’s geological modelling and mine planning software, MinePlan version 16.0.4. The block model was developed using NAD 1983 UTM Zone 6N and is in metric units. The block size is 40 m (X), 20 m (Y) and 5 m (Z) rotated by 20 degrees toward the east to align the X-axis along strike at 110 degrees. The block model captures three mineralized ultramafic intrusive bodies (“zones” or “solids”) that dip towards the southwest at between 45 and 50 degrees.
These three zones are called Eureka Zone 1 (EZ1), Eureka Zone 2 (EZ2), and Eureka Zone 3 (EZ3) from south to north across the deposit, respectively. The three mineralization zones are further divided into west and east areas separated by faulting.
The mineralized zones were built using Seequent’s Leapfrog Geo software from a drill hole database of 37 drill holes. Mineral sample assays have been validated in eight (8) of the 37 drill holes and assay data from these holes has been used to estimate grades for nickel (Ni), copper (Cu), cobalt (Co), platinum (Pt), palladium (Pd), gold (Au), silver (Ag), iron (Fe) and chromium (Cr). All metals, excluding Ag, Fe and Cr, have been used to calculate a Ni equivalent grade based on average (24 month) market prices. Only Au grades were capped prior to estimation at 55 parts per billion (ppb) for the Eureka 2 zone and 30 ppb for the Eureka 3 zone. Ni is approximately 76% of the total value of the metals included in the equivalent grade calculation.
Reasonable prospects for economic extraction have been determined by calculating a Ni cutoff grade of 0.20 percent (%) using the following assumptions:
- Mining costs US$2.5/tonne;
- Processing costs US$25/tonne;
- Overall processing recovery of 60%.
Resources are reported from within an economic pit shell at 45-degree constant slope using Hexagon mining Pseudoflow algorithm. No underground mining is considered.
Assumed revenue used to drive the pit shell is US$10.9/lb Ni applied to a recovered Niequivalent grade assuming 60% recovery for Ni and 50% recovery for all other metal equivalents. This pit optimization does not represent an economic study. Future engineering studies will be needed to develop optimal bulk tonnage mining methods. The pit-constrained maiden MRE is at inferred-level of assurance based in the quantity of exploration data available for grade estimation. Mineral resources are only reported for the Eureka 2 zone and Eureka 3 zone.
The Nikolai Project Maiden MRE, with an effective date of November 20, 2023, is shown in Table 1 and associated grade sensitivity is shown in Table 2.
MINERAL RESOURCE ESTIMATE PREPARATION
The MRE has been prepared by Derek Loveday, P. Geo. of Stantec Consulting Services Inc. in conformity with CIM “Estimation of Mineral Resource and Mineral Reserves Best Practices” guidelines and is reported in accordance with NI 43-101.
Mr. Loveday is a qualified person (“QP”) as defined in NI 43-101 and is independent of the Company. The QP is not aware of any environmental, permitting, legal, title, taxation, socioeconomic, marketing, political, or other relevant issues that could potentially affect this Mineral Resource Estimate. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that any mineral resource will be converted into mineral reserve.
METALLURGY
All three deposits in the 2023 Resource contain desirable nickel sulfide mineralization consisting of thick, layered horizons of nickel and copper sulfides, which are enriched in cobalt, platinum, palladium, and gold. Preliminary deportment assessments for the EZ2 mineralization were completed by Pure Nickel Inc. in 2014 (press release dated April 22, 2014) and the Company in 2022 (press release dated September 29, 2022).
Results from these two assessments (Table 3) indicate an average of 83.4% of the total nickel is in potentially recoverable phases of Ni-sulfides and Ni-Fe alloys. The Company also analyzed copper deportment at that time, with an average of 74% of the total copper in potentially recoverable phases of Cu-sulfides and Cu-oxides. Additional deportment studies and bench scale testing are ongoing with core samples from the 2023 step-out drill program. Results from ongoing studies will be released when completed.
