Visible Gold Assaying 64.1 g/t Gold Within 20.4 Metre Interval Grading
3.54 g/t Gold
Toronto, ON – September 4, 2025 – Critical One Energy Inc. (formerly Madison Metals Inc.)
(“Critical One” or the “Company”) (CSE: CRTL) (OTCQB: MMTLF) (FSE: 4EF0) is pleased to
announce the acquisition of the KCR Gold Project (“KCR Project”) including the Slam Gold Zone
discovery (Figure 1) contiguous to the Company’s extensive land holdings at the Howells Lake
Antimony-Gold Project (“Howells Lake Project”), located approximately 200 kilometres (km) from
the Ring of Fire corridor in the Thunder Bay Mining Division of Ontario, Canada1.

Highlight Details
Compelling discovery Visible gold (“VG”) mineralization discovered in a single historic drill hole –
remains untested in all directions.
Historic soil anomaly Drill testing of a soil anomaly first identified in 1984, but only tested in 2010,
resulted in alteration and VG with assays up to 64.1 g/t over one (1) metre
(m) in the only hole drilled to date on the new Slam Gold discovery (Figures
2 and 3)³.
Discovery hole results Slam Gold Zone discovery averaged 3.54 g/t Au over 20.4 m (Figure 3)³,
100 m below a gold geochemical target that showed more than 1 km of
anomalous results².
(Not all core assayed; unassayed intervals given zero grade for
calculations. See note below.)
Follow-up work Assays were received after drill demobilization, and no further work was
completed.
Untested potential Slam Gold Zone remains completely untested above, below, and along
strike. No outcrop is exposed.
Geochemistry footprint (1984) Anomalous results linked to Slam Gold Zone may have a surface
expression >900 m² (Figure 2).
Historic gold identification Gold was first identified on the KCR Property in the 1930s³.
Historic trenching results • 1974 (New Jersey Zinc): 16.42 g/t Au over 3.35 m⁴.
• 1980 (New Jersey Zinc): 12.82 g/t Au over 4.11 m⁴ (Figure 3).
Drill testing under trenches Discovery hole (MM1001) intersected 9.79 g/t Au over 3.8 m from 17.4 m³
in upper Slam Gold Zone (Figure 3).
Strategic land position Critical One now controls >30 km of the geological trend, covering all
known strongly altered and underexplored antimony-gold targets.

Critical One acquired 100% interest in the KCR Property, subject only to a 2% Net Smelter Royalty
(NSR). The Company now contro ls 100% of all the high-priority exploration land in the Howells
Lake area, having assembled a total land package of more than 25,000 hectares covering all the
known gold and antimony occurrences and strong alteration and deformation discovered to date
in the region.
The gold minerali zation on the KCR Property is related to strong carbonate, biotite alteration,
minor quartz veining , moderate shearing, and various felsic intrusive rocks , as well as sericite
alteration, fine pyrite and minor pyrrhotite . The KCR Property and the other extensive land
positions now held 100% by the Company were all identified and acquired by the Company over
the past eight months.
Prior to this acquisition, Critical One had already acquired all the prospective land adjacent to the
KCR Property and was in the process of carrying out a new, state-of-the-art airborne geophysical
survey of the Company’s property position. On the basis of the pending acquisition, Critical One
ensured it collected detailed data in the area covering and proximal to the Slam Gold discovery.
“The acquisition of this key property covering a completely unevaluated VG-bearing discovery,
which includes numerous gold values occurring over a drilled width of 20.4 metres, shows the
camp-scale potential of our Howells Lake Project,” said Duane Parnham, Founder, Executive
Chairman and CEO of Critical One. “With our land acquisition complete and the evaluation and
interpretation of our new geophysical database being finalized, we will soon be in a position to
determine where we can discover a lot more gold and antimony on our property, which now covers
all significant antimony and gold targets over a 30-kilometre strike length.”
Parnham continued, “The presence of VG in the only hole to ever test this geochemical target
speaks volumes about its potential to host a lot more gold mineralization. Not only was there VG
with a very high gold assay, but there were several other significant gold values not far from the
VG. There was even anomalous gold mineralization at the bottom of the drill hole. By securing
100% interest in this key property, we have added significantly to the gold discovery potential on
our project.”
This strategic acquisition follows the Company’s ongoing review and analysis of historic work on
and proximal to its extensive land holdings in the Howells-Miminiska area.
Critical One is awaiting results of the evaluation and review of its recently completed VTEM
airborne geophysics completed by Geotech Ltd. over the Howells Lake Project. The geophysical
data is currently being processed to provide details on specific target selection , definition and
interpretation. Additional news will be released as this work progresses.
The Howells Lake Project hosts a historical resource of 1.7 million tons at a grade of 1.4%
antimony with associated gold mineralization. The resource is not NI 43-101 compliant and
therefore readers should not rely on the information . The resource estimate does not include
categories as required under NI 43-101 and the report predates NI 43-101 by decades. Given the
work was completed more than 40 years ago, all work will need to be redone as the historic work
cannot be used in a NI 43-101 compliant report. Geological mapping as well as significant drilling
will be required to establish a NI 43-101 resource estimate for the known antimony mineralization.
The resource presented in the report does not provide the parameters used in the preparation of
the resource estimate (tonnage estimate). Historical Report Reference: Themistocleous, S.G.,

*Note: All geological and assay information contained in this document is historical in nature and
the Qualified Person (“QP”) responsible for the technical disclosure in this release is unable to
determine if any of that data would meet current NI 43 -101 regulations regarding disclosure of
scientific and technical information. Additionally, the QP has not done sufficient work to make the
resource current. Drill intersections are reported as downhole intervals. No true width could be
determined at this time. The information in the data recovered is considered of value and relevant
to the Company’s project. However, the Issuer is not treating the estimate as current. The overall
20.4 metre interval grading 3.54 g/t was derived from the original assay certificates that were
available in the public domain and included sections that were not assayed and were therefore
averaged at 0 g/t in the weighted average for the interval.
Critical One is advancing its exploration program plans for follow -up drilling to further delineate
and expand the antimony -gold resource. Supported by a recent private placement of CDN$3 .3
million and a clean capital structure with approximately 50 million common shares ou tstanding,
the Company is fully funded for near-term exploration, including a maiden drill program on the V-
3 historical antimony deposit and drilling of other antimony-gold target zones such as the Slam
Gold Discovery covered in this press release.
