QUEST CRITICAL METALS ANNOUNCES COMPLETION OF DIAMOND DRILL HOLE TESTING A STRONG IP ANOMALY IN THE AREA OF THE TISOVA-KLINGENTHAL CU-CO DEPOSIT

Quest Critical Metals Inc. has received the results for the recently completed diamond drill hole testing of a strong IP (induced polarization) anomaly stratigraphically below the historical copper mine workings. Quest's Tisova-Klingenthal licence area, centred on the Tisova mine, which was actively mined from 1627 until 1970, has shown promising results. The historical sulphide zones contained grades up to 17.1 per cent copper (Cu), 0.69 per cent cobalt (Co) and 3.7 grams per tonne (g/t) gold (Au).

The drill target was generated from the 2019 IP and resistivity survey data. In 2024, the geophysical data were reprocessed and remodelled by independent geophysicists, confirming the same IP anomaly. The program comprised two diamond drill holes, with the initial hole being abandoned at 393 metres, due to faulting.

The second 479.5-metre diamond (azimuth of 80 degrees, dip of minus 85 degrees) drill hole intersected:

• 4.3 metres of mine stratigraphy, 67.3 to 71.6 metres, assaying 1,901 parts per billion (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 to 5 per cent 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 centred on the Tisova mine, which was actively mined from 1627 until 1970, has shown historic sulphide zones with grades up to 17.1 per cent Cu, 0.69 per cent Co and 3.7 g/t Au.

Quest's Tisova-Klingenthal Cu-Co deposit was the test site of the European Union-financed (EU) 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 data sets, 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 mineralization, including the historical Tisova 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.
