Premier American Uranium and American Future Fuel Announce
Updated Mineral Resource Estimate for the Cebolleta Project,
Setting the Stage for Planned Expansion Drilling
Toronto, ON, June 24, 2024 – Premier American Uranium Inc. (“PUR” or “Premier American Uranium”) (TSXV:
PUR) (OTCQB: PAUIF) and American Future Fuel Corporation (“AMPS” or “American Future Fuel”) (CSE: AMPS,
OTCQB: AFFCF, FWB: K14, WKN: A3DQFB) are pleased to announce a current mineral resource estimate and the
filing of a Technical Report (the “Technical Report”) for the 100% owned Cebolleta Uranium Project located in
Cibola County, New Mexico, US (the “ Project”) prepared in accordance with National Instrument 43 -101 –
Standards of Disclosure for Mineral Projects (“NI 43-101”). The Technical Report is being filed under both PUR
and AMPS’ respective profiles on SEDAR+ at www.sedarplus.ca, in connection with the previously announced
Plan of Arrangement involving the companies (the “Arrangement”) which is expected to close later this
week. The Technical Report, prepared by SLR International Corporation (“SLR”) with an effective date of April
30, 2024, includes a current Mineral Resource Estimate ( “MRE”) for the Project and in line with
recommendations, lays the foundation for future exploration to support a planned Preliminary Economic
Assessment (“PEA”).
Highlights of the Technical Report
• The MRE is based on a commodity price of US$80.00 per pound of U3O8 using an underground mining
cut-off grade of 0.072% eU3O8 and an open pit mining cut-off grade of 0.024% eU3O8, reported as an:
o Indicated Mineral Resource totaling 18.6 million pounds of eU3O8 (6.6 million short tons at an
average grade of 0.14% eU3O8).
o Inferred Mineral Resource totaling 4.9 million pounds eU3O8 (2.6 million short tons at an
average grade of 0.10% eU3O8).
• The MRE underscores the Project’s extensive exploration and operating history, incorporating reliable
historical data and previously unaccounted areas such as the St. Anthony North pit, while factoring in
depletion from past production (Figure 1).
• The current MRE exceeds the historical Inferred Mineral Resource that was prepared for Uranium
Resources, Inc. (AMPS’ predecessor) in 2014 , upgrading approximately 80% of previous Inferred
Mineral Resource to the Indicated Mineral Resource category.
• Key recommendations outlined in the Technical Report include:
o Exploration to expand the deposit footprint with potentially positive implications to a mining
scenario.
o Collection of additional bulk density and chemical assays in future drilling to confirm historical
reported density and radiometric equilibrium results.
o Updating the MRE with additional drill hole data and completing a PEA.
• Strong exploration potential remains at the Project with potential to increase total mineral resources
through exploration and expansion drilling in previously untested areas where the mineralized
horizons of the Jackpile sandstone are open ended beyond the currently drilled area. Further work to
de-risk the Project is expected to include infill drilling to u pgrade Inferred Mineral Resource to
Indicated Mineral Resource along currently mapped uranium mineralization. The Willie P area, which
is not included in the MRE but was the site of previous underground mine operations, is believed to
have resource potential which may be augmented by integrating additional historic radiometric logs
and grade information into the resource model.
Colin Healey, CEO of PUR , commented, “We are extremely pleased to announce the updated Technical Report
on Cebolleta. This asset was identified by our seasoned technical team as “highly attractive” for its resource
potential, grade and favourable location on private lands in New Mexico. The new Technical Report represents
a significant step forward for PUR and the Project, delivering a current MRE for the first t ime in a decade, and
ahead of plan . The Mineral Resource estimate now exceeds the 2014 historic al I nferred Mineral Resource
estimate, confirming 18.6Mlb U3O8 in Indicated and 4.9Mlb U3O8 in Inferred (~80% ‘Indicated’, ~20% ‘Inferred’)
and our exploration strategy can now transition from confirmation drilling to extension and expansion drilling as
we work toward completing a Preliminary Economic Assessment (PEA), as recommended in the Technical Report.
We believe that prioritizing our budget around these higher-impact initiatives should deliver enhanced value to
shareholders with the potential to add resource pounds in new areas as we build out a mining concept. We thank
all the technical staff and contractors for their contribution in achieving this major milestone and we are excited
for the next phase of work at Cebolleta.”

shapes and 0.024% eU3O8 for open pit using Whittle pit optimization.
3. Mineral Resources are estimated using a long-term uranium price of US$80/lb U3O8.
4. Mineral Resources have been depleted based on past reported production numbers from the underground JJ#1 and
Climax M6 mines.
5. A minimum mining width of two feet was used.
6. Tonnage Factor is 16 ft3/st (Density is 0.625 st/ft3 or 2.00 t/m3).
7. Numbers may not add due to rounding.
Mineral Resources are not Mineral Reserves, and do not have demonstrated economic viability. The authors of
the Technical Report were not aware of any environmental, permitting, legal, title, taxation, socio -economic,
marketing, political, or other relevant factors that could materially affect the MRE.
Technical Report
Mineral Resources have been classified in accordance with Canadian Institute of Mining, Metallurgy and
Petroleum (CIM) Definition Standards for Mineral Resources and Mineral Reserves dated May 10, 2014 (CIM
(2014) definitions).
The MRE was completed using a conventional block modelling approach. The general workflow used by SLR
included the construction of a geological or stratigraphic model representing the Jurassic Morrison Formation in
Seequent’s Leapfrog Geo (Leapfrog Geo) from mapping, drill hole logging, and sampling data, which was used to
define discrete domain and surfaces representing the upper and lower contact of the Jackpile Sandstone
Member. The geologic models were then used to constrain resource estimation completed using Seequent’s
Leapfrog Edge (Leapfrog Edge) software. The MRE used a regularized, unrotated whole block approach, inverse
distance cube d (ID3) interpolation methodology, and one -foot uncapped composites to estimate the eU 3O8
grades in a three -pass search approach. Hard boundaries were used with ellipsoidal search ranges, and search
ellipse orientation was informed by geology and mineralization wireframing. Density values were assigned based
on historical bulk density records.
Estimates were validated using standard industry techniques including statistical comparisons with composite
samples and parallel inverse distance squared (ID2), ordinary kriging (OK) and nearest neighbor (NN) estimates,
swath plots, and visual reviews in cross section and plan. A visual review comparing blocks to drill holes was
completed after the block modelling work was performed to ensure general lithologic and analytical
conformance and was peer reviewed prior to finalization.
Rotary and diamond drilling (core) on the property was the principal method of exploration and delineation of
uranium mineralization. From 1951 to 2014 and 2023, AMPS and its predecessors completed a reported total of
3,644 drill holes, of which 3,594 drill holes totaling 1,868,457 ft of drilling are contained in the drilling database
provided to SLR. Of the 3,594 drill holes, 2,713 drill holes totaling 1,380,041 ft of drilling were used in the MRE.
Historic surface holes missing collar information, lithology information, or corresponding radiometric logs, i.e.,
assay data, were excluded. A summary of the available data used in the modeling of mineralization is presented
in Table 2.

Figure 1: Plan View Map of the Cebolleta Uranium Project and Uranium Deposits
As described below and depicted above in Figure 1, t he deposits that comprise the Project are classified as
sandstone hosted uranium deposits with eight deposits occurring as a series of tabular bodies within the Jackpile
Sandstone Member of the Upper Jurassic Morrison Formation within the boundaries of property.
These deposits are part of a broad and extensive area of uranium mineralization, including the Jackpile-Paguate
deposit, located adjacent to the southern boundary of the property, which was one of the largest concentrations
of uranium mineralization in the United States (Moran and Daviess, 2014). The L -Bar occurrence area contains
five distinct deposits, including Areas I, II, III, IV, and V. The historical JJ#1 Mine is situated in the northwest corner
of the Area II Deposit area. In addition to the L-Bar deposits, three distinct deposits occur in the St. Anthony area
of the property.
The production history of the Project is as follows:
• Climax M6 Mine (1956 to 1960): 78,722 short tons (71,415 tonnes) that averaged 0.20% uranium oxide
(U3O8) and contained 320,942 pounds of U3O8.
• St. Anthony Mine Complex (1975 to 1979): 1.6 million pounds of U3O8.
• Sohio JJ#1 Mine (1976-1981): 898,600 short tons averaging 0.123% U3O8 and yielding 2,218,800 pounds
of U3O8.
Significant exploration potential is believed to remain on the Project. The mineralized horizons of the Jackpile
sandstone are open ended and potentially trend beyond the external limits of the drill hole grid. Potential exists
to extend mineralization into previously untested areas of the Project, where this mineralized zone is present
but not drill tested in a comprehensive manner.
