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

·      Drilling of hole HMO-008 has now been completed. This is the
first drill hole of the recently commenced resource upgrade to Indicated
status.

 

·      A 2.5m wide zone of visible zinc mineralisation was encountered
high in the hole.

 

·      Within this 2.5m interval, five (5) portable XRF spot samples
have been taken, which average 6.7% Zn, 2.5% Pb and 42g/t Ag. The highest
individual spot sample for zinc is 18.7% Zn. This zone has been cut, sampled
and sent to the laboratory for analysis. The pXRF equipment does not measure
germanium values, but germanium will be analysed at the laboratory.

 

·      In addition to testing these upper lodes, hole HMO-008 also aimed
to test mineralisation at much greater depths. The hole is dominated by
extensive fault zones, shears, brecciation and fracturing, which resulted in
very slow and difficult drilling conditions.

 

·       The entire drill core from surface to 289.00m depth is
extremely altered with epidote, silica, carbonate, chlorite and clay. It is
interpreted that this hole unintentionally drilled directly down one of the
growth faults which are responsible for the thickening of mineralised
sedimentary units.

 

·       The position of this hole, and the presence of the growth fault
provides the team with valuable geological and mineralisation knowledge,
particularly of the growth fault characteristics and orientation. This is the
first time that a hole has drilled directly down one of these faults, so the
hole was pushed to greater depths, resulting in a very slow rate of drilling.

 

·       The drill rig has moved to the second hole site. Drilling of
future holes is expected to be faster as the position of the rig moves away
from the growth fault.

 

·       A second drill rig is being sought to increase the rate of
drilling productivity.

 

 

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.

The yellow/green colour is epidote alteration, the pink is iron staining

and the white is clay/carbonate alteration.

 

David Price, Chief Executive Officer of Rockfire, commented:

"This drill hole has proved extremely difficult to drill and is without
question, the most fractured, broken and brecciated hole drilled at Molaoi so
far. It is thought that hole HMO-008 has drilled directly down one of the
growth faults. These faults have provided the geological setting for thicker
mineralised lodes at depth. It was hoped that, by drilling deeper, the hole
might exit the fault into strong mineralisation, however the hole remained in
the fault for its entire length."

"The upper lodes were intersected in the anticipated position, and these lodes
are currently being analysed. The rig has moved to the south to start the
second hole, and we expect the rate of drilling to be faster. A second drill
rig is also being sought to increase the company's rate of drilling."

 

"Shareholders can take comfort that not all our drill holes are expected to
take this length of time and hole HMO-008 is extremely unusual. The intensity
of alteration, and the extremely broken ground made for difficult and slow
drilling conditions. The decision to push deeper to get through the fault zone
was taken, however the fault proved far more extensive than first thought.
This hole has provided excellent geological information within the fault which
will enable us to model the fault into our updated Indicated resource."

 

"We look forward to providing more updates as our drilling continues."

Australia.

·      The Molaoi deposit in Greece has a JORC Inferred Mineral
Resource of 15.0 million tonnes @ 7.26% Zn, 1.75% Pb and 39.50g/t Ag, for 1.5
million tonnes of ZnEq. metal. This resource uses a 4% low-grade cut, and
equates to 1.09 million tonnes of zinc, 260,000 tonnes of lead and 19.1
million ounces of silver.

 

·      The Plateau deposit in Queensland has a JORC Inferred
Resource of 131,000 ounces of gold and 800,000 ounces of silver, using a
0.5g/t Au cut off. 53,000 of these ounces lie within the top 100m from
