Quest Critical Metals Announces Completion of Diamond Drill Hole Testing a Strong IP Anomaly in the Area of the Tisova-Klingenthal Cu-Co Deposit
FOR IMMEDIATE RELEASE
QUEST CRITICAL METALS ANNOUNCES COMPLETION OF DIAMOND
DRILL HOLE TESTING A STRONG IP ANOMALY IN THE AREA OF THE
TISOVA-KLINGENTHAL CU-CO DEPOSIT
Vancouver, BC – September 19, 2025 – Quest Critical Metals Inc (“Quest ” or the
“Company”) (CSE: BULL, OTC: DCNNF, FSE: DCR0) has received the results for the
recently completed diamond drill hole testing of a strong IP anomaly stratigraphically
below the historic copper mine workings. Quest’s Tisová /Klingenthal license area,
centered on the Tisová Mine, which was actively mined from 1627 until 1970, has shown
promising results. The historic sulphide zones contained grades up to 17.1% Cu, 0.69%
Co, and 3.7g/t Au.
The drill target was generated from the 2019 IP and resistivity survey data. In 2024, the
geophysical data was reprocessed and remodelled by independent geophysicists,
confirming the same IP anomaly. The program comprised 2 diamond drill holes, with the
initial hole being abandoned at 393 metres. due to faulting.
The second 479.5 metre diamond (Azimuth 80 degrees, Dip - 85 degrees) drill hole
intersected:
4.3 metres of mine stratigraphy , 67.3 to 71.6 metres , assaying 1901 ppb Copper.
Including 2.0 metres of 0.2 ppm of gold. This zone of mineralization is interpreted as the
main historically mined ore zone.
76.5 metres of 2-5% disseminated pyrite within a strongly silica, phyllitic altered zone from
328.7 to 406 metres. Though barren, this horizon fits within the Besshi Type Deposit
model as a strongly altered stratigraphic section. All intersections are close to true width.
Analysis of core samples was completed by ALS Romania SRL.
Quest’s Tisova/Klingenthal licence area is centered on the Tisova Mine, which was
actively mined from 1627 until 1970 , has shown historic sulphide zones w ith grades up
to 17.1% Cu, 0.69% Co, 3.7g/t Au.
Quest’s Tisová–Klingenthal Cu–Co deposit was the test site of the European Union (EU)-
funded Exploration Information System (EIS) project, which aimed to develop innovative
exploration concepts and advanced data analysis tools to increase the likelihood of
discovering new sources of critical raw materials vital for the EU’s economy. Utilizing the
Exploration Information System (EIS) toolkit, a knowledge- driven Fuzzy Logic approach
was developed to integrate key spatial datasets, including buffered Copper and zinc soil
and stream sediment anomalies and metabasaltic lithology, relevant to Besshi -type
Volcanogenic Massive Sulphide deposits.
The prospectivity model defined anomalies of potential mineralisation, including the
historic Tisová deposit and additional targets aligned along the same stratigraphic horizon
that require further exploration follow-up.
The Company remains encouraged by the project’s underlying potential and is committed
to advancing exploration efforts to define future drill targets.

words, or statements that certain events or conditions "may" or "will" occur. In particular,
forward-looking information in this press release includes, but is not limited to, statements with
respect to the Company's diamond drill hole testing and results. Although we believe that the
expectations reflected in the forward- looking information are reasonable, there can be no
assurance that such expectations will prove to be correct. We cannot guarantee future results,
performance or achievements. Consequently, there is no representation that the actual results
achieved will be the same, in whole or in part, as those set out in the forward-looking information.

acceptable terms; the need to obtain required approvals from regulatory authorities; stock market
volatility; liabilities inherent in water disposal facility operations; competition for, among other
things, skilled personnel and supplies; incorrect assessments of the value of acquisitions;
geological, technical, processing and transportation problems; changes in tax laws and incentive
programs; failure to realize the anticipated benefits of acquisitions and dispositions; and the other
factors. Readers are cautioned that this list of risk factors should not be construed as exhaustive.
