Molaoi Drilling Update

Rockfire Resources plc (LON: ROCK), the base metal, critical mineral and
precious metal exploration company, provides the market with this drilling
update from Rockfire's 100%-owned Molaoi zinc deposit in Greece.

Highlights

·       The third drill hole, (HMO-010) has completed successfully at
275.80m depth.

 

·       Multiple mineralised intervals have been intersected in line
with our expectations from resource modelling, with peak pXRF values of 36.55%
Zn, 325ppm Ag, 5.1% Pb and 1.3% Cu.

 

·       Between 97.40m and 97.70m depth (0.3m), pXRF readings average
8.25% Zn, with peak values of 13.86% Zn, 1.15% Pb and 76.67ppm Ag.

 

·       From 198.50m to 200.70m (2.2m), a zone of mineralisation
detected by pXRF readings averages 2.0% Zn and 1.80% Pb. This zone has
readings peaking at 3.94% Zn and 5.1% Pb.

 

·       The same zone from 198.50m depth has returned very strong
individual pXRF readings for silver (325ppm Ag) and copper (1.3% Cu).

 

·       Molaoi hosts 19.1 million ounces of silver and copper is known
to be throughout the mineralisation. Up to 2% Cu reports to the silver/lead
flotation concentrate.

 

·       Another zone between 238.80m and 239.15m (0.39m) averages 9.07%
Zn, 3.2% Pb and 19g/t Ag. A peak reading of 14.8% Zn has been recorded in this
interval.

 

·       Finally, from 258.65m to 260.00m (1.35m), a peak pXRF value of
36.55% Zn is within an average interval of 13.82% Zn.

 

·       All pXRF readings are considered preliminary and all the
intervals identified will be analysed accurately at ALS Laboratories in
Ireland.

 

·       The pXRF equipment does not measure germanium values, but
germanium will be analysed at the laboratory.

 

·       At the completion of this current drilling campaign, it is
expected that Molaoi will host the only defined Inferred Resource of germanium
in Europe and one of only two quoted germanium resources globally.

 

 

 

 

 

 

 

 

The cleanliness of the pXRF machine was established by measuring a BLANK
reference material (a translucent quartz crystal) at the beginning of each
day. A Certified Reference Material (CRM) specific to volcanic-hosted massive
sulphide Zn-Pb-Cu-Ag-Au ore (ORES 620) was measured for accuracy/precision of
the pXRF machine with a reading taken at the beginning of each day.

 

 

 

David Price, Chief Executive Officer of Rockfire, commented:

"Our drilling program continues well, and our third drill hole has
successfully intersected multiple lodes predicted by our mineralisation
modelling. The portable XRF readings throughout the hole continue to return
high values, all of which will be confirmed by full and accurate analysis at
the laboratory."

"Hole HMO-011 has commenced and is currently in progress. The Christmas period
is rapidly approaching, and the drill team will shortly break for the
Christmas/New Year holiday. There will be a pause in drilling from the 20(th)
of December, with drilling expected to resume on the 12(th) of January. A
second drill rig is expected to be in operation sometime during January 2026."

"The zinc resource at Molaoi is 2.2km long and drilling of the next 27 holes
will continue in the new year. Our objective is to increase the
zinc/silver/lead resource confidence from Inferred to Indicated and drilling
is expected to continue throughout the first half of 2026."

"We will continue to update the market with analytical results from the
laboratory in the interim."
