Further Research by the University of Patras, Greece

Additional Critical Minerals identified in sulphides at Molaoi

 

Rockfire Resources plc (LON: ROCK), the base metal, critical mineral and
precious metal exploration company, is pleased to update shareholders of
on-going findings by scientists at the University of Patras at Rockfire's
100%-owned Molaoi zinc deposit in Greece. The University of Patras is a
3.5-hour drive from Molaoi.

Some of the key findings from this on-going research are:

·    Using Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry
analysis ('LA-ICP-MS'), sphalerite crystals have been found to host high-grade
gallium up to 858 g/t Ga and a peak silver value of 3,364 g/t Ag.

 

·    Surprisingly, pyrite crystals at Molaoi are also a strong host of
other high-value minerals, including maximum values of 20.7% Ni, 1.37% Cu and
245.0 g/t Au

 

This research has positive implications for the future exploration strategy
and may contribute to the long-term economics of the project. It is yet to be
determined if any of these elements can be extracted in sufficient quantities,
or at economic grades.

 

·     Gallium is typically elevated (less than 30g/t Ga) in Rockfire's
drill core, but currently it is unknown if gallium reports to any of the
concentrates as a by-product. This will be tested in the next round of
metallurgical test work.

 

·     Nickel and copper are routinely analysed in Rockfire drill holes
and values are typically low (Ni less than 30g/t and Cu less than 500g/t). In
metallurgical tests done by Rockfire so far, copper reports to a lead-silver
concentrate with grades of 2% Cu, which may prove to be a valuable by-product.
It is not known if nickel reports to any of the concentrates as a by-product.

 

·     Gold is only sporadically analysed in the Rockfire core, and
specifically in zones of intense silicification and within veins. Values are
typically low (less than 0.05g/t), but gold is known to report to a
lead-silver concentrate with grades of 0.5g/t, again proving the potential for
another high-value by-product.

 

Under the leadership of Dr. Stellios Tombros, the University of Patras has a
multidisciplinary and integrative research team conducting an advanced
scientific study of the germanium (Ge) potential of the Molaoi Zn-Pb (± Ag,
Ge) ore deposit.

 

 

David Price, Chief Executive Officer of Rockfire, commented:

"The research being undertaken on rocks from Molaoi continues to unearth
surprises and key findings. It is this excellent work by Dr. Tombros and the
team at the University of Patras that will enable Rockfire to understand the
emplacement, form, geochemistry, extractability, and commercial aspects of the
multiple critical, base and precious metals being identified at Molaoi."

"Of the recent findings, the nickel and high-grade gold are the two biggest
surprises, providing further evidence that Molaoi is more akin to a deposit
formed in an epithermal setting. It is becoming more apparent that the Molaoi
deposit is the result of a continuously evolving ore deposit, with multiple
mineralizing episodes."

"It is yet to be determined if any of these elements can be extracted in
sufficient quantities, or at economic grades. It is encouraging to learn that
these metals are present at high grades within the sulphides at Molaoi. The
ability to extract any of these elements commercially will be determined in
the next round of planned metallurgical test work."

"With drilling now underway, the Company is determined to lift the resource
confidence, leading to feasibility as quickly as possible. The market will be
informed as drilling results become available."

Notes to Editors

Rockfire Resources plc (LON: ROCK) is a gold, base metal and critical mineral
exploration company, with a high-grade zinc/lead/silver/germanium deposit
in Greece and a portfolio of gold/copper/silver projects in Queensland
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 resource of 131,000
ounces of gold and 800,000 ounces of silver, using a 0.5g/t Au cut off. 53,000
