Initial Tin and Copper Metallurgy Testing Results

 

Rome Resources plc (AIM: RMR), the DRC-focused tin and copper explorer, is
pleased to provide an update on the initial results from metallurgical testing
of ore samples from its Bisie North project in the Democratic Republic of
Congo ("DRC"), located just 8 km from the world-class Alphamin Mpama tin mine
complex. This update follows the drilling update provided on 16 January 2026.

 

Metallurgical testing was undertaken by SGS on bulk samples from the tin,
copper and zinc zones in order to assess the potential for commercial recovery
of the various commodity metals from the ore.  The results for copper and tin
recovery are encouraging.

 

·   The tin zone sample has responded well to gravity pre-concentration
with 80% of the Sn reporting to a first concentrate at a grade of over 10% Sn
from a head grade of 0.6% Sn in less than 5% of the mass.

 

·   The copper zone sample has also responded well to gravity
pre-concentration with 96% of the Cu reporting to a concentrate at a grade of
3.7% Cu from a head grade of 2.4% Cu in less than 63% of the mass.

 

·   The copper sample responded very well to flotation with 95.5% of the
Cu reporting to the rougher flotation at a grade of 9.5% Cu. The Zn in this
sample followed the Cu and differential flotation may therefore be considered
to separate the Cu and Zn.

 

In all cases customary cleaning of the tin and copper concentrates will be
required in order to raise the grade to export levels.

 

Paul Barrett, Chief Executive Officer of Rome Resources, said:

"These preliminary results are highly encouraging for the potential
commercialisation of both the tin and copper at Bisie North.  As the copper
is developed at shallow depths in the Mont Agoma deposit, recovery and
monetisation of this is expected to be highly accretive to the overall project
economics.

 

Currently, the drilling campaign at Kalayi continues and we will move to Mont
Agoma next month to test further the extent of the tin and copper
mineralisation. We will update the market in due course."
