Molaoi Drilling Update

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

Highlights

·      Results from drill hole HMO-015 have been received from the
laboratory, with highlights below.

 

o  0.82m @ 8.7% Zn, 28.5g/t Ag, and 27.4g/t Ge from 350m downhole depth

o  11.9m @ 8.8% Zn, 49.0g/t Ag and 25.2g/t Ge from 354.90m downhole depth

o  3.02m @ 7.5% Zn, 40.9g/t Ag, 19.0g/t Ge and 1.3% Pb from 386.28m downhole
depth

 

*** Please note that quoted widths are downhole widths ***

·      Diamond drilling to upgrade the Inferred Resource to Indicated
Resource status continues with hole HMO-017 currently in progress.

 

·      Portable XRF ("pXRF") readings being recorded in hole HMO-017 are
encouraging, with individual, spot zinc values up to 51% Zn, 72g/t Ag, 0.38%
Cu and 5.1% Pb being recorded over narrow intervals at a depth of
approximately 288m from surface. The pXRF does not measure germanium.

 

·       Results of core samples from hole HMO-016 are awaited from the
laboratory.

 

The cleanliness of the pXRF machine is 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) is 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:

"Hole HMO-015 is drilled within the main zone of mineralisation at Molaoi,
which extends for more than 1,300m north-south. Similar, previous, strong
intervals within 65m of hole HMO-015 include:

HMO-004 - 8.8m @ 8.8% Zn, 49.0g/t Ag, 16.0g/t Ge from 258.4m depth (Rockfire
hole)

AN007 - 12.3m @ 4.8% Zn, 20.0g/t Ag, 1.13% Pb from 120.1m depth (historical
hole)

AN004 - 4.0m @ 8.5% Zn, 36g/t Ag, 1.85% Pb from 134.3m depth (historical hole)

HMO-003 - 3.6m @ 6.0% Zn, 32.5g/t Ag, 1.1g/t Pb, 17.4g/t Ge from 202.5m depth
(Rockfire hole)

B035 - 3.0m @ 7.0% Zn, 39.5g/t Ag and 2.88% Pb from 255.3m depth (historical
hole)

AN006 - 3.7m @ 14.3% Zn, 52.0g/t Ag, 1.4% Pb from 99.50m depth (historical
hole)"

*** Please note that quoted widths are downhole widths ***

"As shown in the above examples, there is considerable variation of both grade
and width of the mineralised lodes. This variation is expected in mineral
deposits, however the critical characteristic of Molaoi to remember is that
every hole in the main lode has intersected zinc, silver, germanium and lead.
The mineralisation continues to be robust and predictable."

"I take this opportunity to highlight that local community support for the
project remains strong and the government in Athens is also strongly
supportive of Rockfire and the drilling activities being undertaken. Our use
of above-ground tanks instead of digging in-ground sumps where possible is
appreciated by the landowners. Rockfire is proud of its track record of not
having destroyed any olive trees, despite drilling between rows of old-growth
trees."

"The market will continue to be informed and updated as new information and
results come to hand."
