JORC 2012 Inferred Mineral Resource Estimate for the Luansobe
Copper Project, Zambia
Galileo Resources plc ("Galileo "or the "Company") is pleased to
announce the results of an initial Inferred Mineral Resource
Estimate for the Luansobe copper project ("Luansobe" or the
"Project") in Zambia, completed by independent consultants Addison
Mining Services. Galileo holds a 75% interest in the Project.
Highlights
-- Inferred Mineral Resources reported in accordance with the JORC code 2012 edition, including;
o Approximately 5.8 million tonnes gross at 1% total Cu above a
cut-off grade of 0.25% total Cu for 56,000 tonnes of contained Cu,
potentially amenable to open pit mining.
o Approximately 6.3 million tonnes gross at 1.5% total Cu above
a cut-off grade of 1% total Cu for 97,000 tonnes of contained Cu,
potentially amenable to underground mining.
-- Additionally, 3.0 to 7.0 million tonne gross exploration
target with grades in the region of 1% to 1.5% total Cu at depths
between 100m to 300m in an underexplored area of the licence where
further drilling may serve to convert this conceptual target to a
mineral resource.
-- Detailed metallurgical test work has already commenced on a
60 kilogram sample of drill core to determine the optimised
processing flow sheet which may contribute to the upgrade of the
Mineral Resource classification.
-- Tendering for mining contractors can commence once an
optimised block model is available as part of general Project
planning work
Colin Bird Chairman & CEO said: " We are very pleased with
the outcome of the Luansobe drill programme and the resultant
tonnage and grade estimate in our maiden inferred resources. We
will now continue the process of optimising a block model and open
pit planning during the current quarter as a basis for engagement
with potential contractors to quote for open pit mining. The timing
of mining start-up will be subject to, amongst other matters, the
ongoing feasibility assessment, completion of mining and processing
agreements, along with necessary Project permitting.
Samples of drill core have been sent to a metallurgical testing
laboratory and are being assessed for amenability to upgrade for
processing elsewhere or construction of an onsite plant. The
results appear to be capable of supporting a 10-year 600,000 tonnes
per year project which would represent a significant operation,
well timed due to the predicted shortage of copper supplies. "
Project Background
The Luansobe area is situated some 15km to the northwest of the
Mufulira Mine in the Zambian Copperbelt which produced well over
9Mt of copper metal during its operation. It forms part of the
northwestern limb of the northwest - southeast trending Mufulira
syncline and is essentially a strike continuation of Mufulira, with
copper mineralisation hosted in the same stratigraphic horizons. At
the Luansobe prospect mineralisation occurs over two contiguous
zones, dipping at 20-30 degrees to the northeast, over a strike
length of about 3km and to a vertical depth of at least 1,250m.
Galileo entered into a Joint Venture agreement with Statunga
Investments Limited ("Statunga" or "the Vendors"), a private
Zambian company which holds the Luansobe Project ("Project")
comprising small-scale exploration licence No. 28340-HQ-SEL in the
Zambian Copperbelt.
The JV Agreement provides Galileo the right to earn an initial
75% interest in a special purpose joint venture company to be
established under Zambia law to, with Ministerial consent, acquire
the exploration licence and the technical data related to the
Luansobe Project by making two payments of US$200,000 each (subject
to project due diligence) by 20 February 2022 and issuing 5,000,000
Galileo shares to the Vendors. These conditions were met by the
Company.
As per our JV agreement, Galileo will continue to evaluate and
optimise Project feasibility in parallel to seeking third party
quotes for contract mining as referred to above.
If a decision to mine is made by Galileo, then the parties will
be entitled to fund pro rata to their beneficial interest in the JV
Company. Any funding shortfall by the Vendors will be recovered
from subsequent mine production.
Mineral Resource Estimate
The initial Mineral Resource Estimate has been completed by
Addison Mining Services Ltd., an independent consultancy based in
the United Kingdom and is reported in accordance with the JORC code
2012 edition. Resources are of the Inferred category and
include.
-- Approximately 5.8 million gross tonnes at 1% total Cu above a
cut-off grade of 0.25% total Cu, potentially amenable to open pit
mining.
-- Approximately 6.3 million gross tonnes at 1.5% total Cu above
a cut-off grade of 1% total Cu, potentially amenable to underground
mining.
The southeast of the Luansobe licence area remains under
explored with insufficient data to allow estimation of a mineral
resource. Historic drilling in this area suggests an exploration
target of approximately 3 million to 7 million tonnes between
depths of 100 to 300m with grades in the region of 1% to 1.5% total
Cu. The target area is approximately 2 km by 1 km in surface
expression. The exploration target is conceptual in nature and may
not be realised. Galileo plans to test the exploration target
following evaluation of the open pit mining potential and, given
favourable results, the commencement of production. Approximately
5,000m of drilling is recommended to test the area.
The Mineral Resource Estimate is based on wireframe restricted
block modelling with grade estimation by ordinary kriging. Pit
optimisation was used to identify material which may be amenable to
open pit mining - these data are presented in Table 1 below above a
cut-off grade off 0.25% total Cu, in addition to Resources that may
be amenable to underground mining techniques above a cut-off grade
of 1% total Cu. For further information see JORC Table 1 below.

The estimate incorporates new drilling by Galileo completed
between 4(th) August and 9(th) November 2022. Galileo drilled 28
diamond holes, totalling of 3,568.4m (ranging between 47.7m and
230.3m in depth). Drillhole size was PQ in overburden with HQ
tails. All drillholes are vertical. In addition, 78 drillholes
completed in 2006-2007 by previous operators Z.C.C.M. Ltd along
with 86 other historical drillholes completed by Roan Consolidated
Mines Ltd in 1950 to 1970 were used in the estimate, 30 of which
were re-logged by independent consultants GeoQuest on behalf of
Galileo. GeoQuest completed pXRF verification of Cu values on the
historic core inspected and sampled previously unsampled
mineralised core for inclusion in the mineral resource
estimate.

Notes relating to Mineral Resource Estimate:
1. The independent Competent Person for the Mineral Resource
Estimate, as defined by the JORC Code (2012 edition), is Mr.
Richard Siddle, MSc, MAIG, of Addison Mining Services Ltd since
November 2014. The effective date of the Mineral Resource Estimate
is 21(st) of December 2022. Mr Siddle has not yet completed a site
visit and as such the Mineral Resources are restricted to the
Inferred category.
2. No mineral reserve estimates have been undertaken. Mineral
resources that are not mineral reserves do not have demonstrated
economic viability. The quantity and grade of reported Inferred
Resources in this Mineral Resource Estimate are uncertain in nature
and there has been insufficient exploration to define these
Inferred Resources as Indicated or Measured, however it is
reasonably expected that the majority of Inferred Mineral Resources
could be upgraded to Indicated Mineral Resources with continued
exploration and verification including improved structural
understanding of the deposit, fault mapping, further verification
of legacy drillholes and metallurgical testing. Following a site
visit by the CP it may be possible to convert some of the Inferred
Mineral Resources to Indicated Mineral Resources.
3. Acid Soluble Cu (%) represents the concentration of copper
that is susceptible to leaching by a 5% sulphuric acid digestion
and is a proxy for the concentration of copper present in oxide
phases. Chalcocite, a secondary sulphide copper mineral may also
report in part to the Acid Soluble Cu. By extension Total Cu (%)
minus Acid Soluble Cu (%) is a proxy for the concentration of
copper in sulphide phases. Estimation of copper phases is important
for future evaluation work as sulphide and oxide copper minerals
maybe processed by different methods such as flotation and leaching
with electrowinning respectively, bulk flotation is also a
possibility. Initial mineral processing testwork has commenced but
has yet to be completed at the time of writing.
4. The Inferred mineral resource category set out in the table
above at cut-off grades >0.25% Total Cu for open pit and 1%
Total Cu for underground mining comply with the resource
definitions as described in the Australasian Code for Reporting of
Exploration Results, Mineral Resources and Ore Reserves. The JORC
Code, 2012 Edition. Prepared by: The Joint Ore Reserves Committee
of The Australasian Institute of Mining and Metallurgy, Australian
Institute of Geoscientists and Minerals Council of Australia
(JORC).
5. Numbers are rounded to reflect the fact that an Estimate of
Resources is being reported. Rounding of numbers may result in
differences in calculated totals and averages. All tonnes are
metric tonnes.
6. Open pit mining assumes a Cu price of US$9000 per tonne with
85% payability on metal in concentrate. Pit optimisation and
cut-off grade selection was based on the assumption of 85% recovery
of total Cu, including the acid soluble component, by flotation at
$14/t plus $1.5/t G&A. Mining costs were assumed as $3/t.
Underground mining was based on the same assumptions with a mining
cost of $40/t.
7. Pit slopes were assumed as 40 degrees in overburden and 50
degrees in fresh rock. No geotechnical studies have been completed
to support this assumption and the requirement for shallower pit
slopes may serve to materially reduce the open pit mineral
resource.
8. The Mineral Resource Estimate set out above was based on the
wireframe interpretation of the mineralised massive shale, lower
dolomite, BC and C quartzites of the "Ore" Formation of the Lower
Roan stratigraphy. Mineralisation is interpreted to dip in the limb
of a syncline to the northeast by 30-40 degrees with locally
shallower sections.
9. The block size was 20 mE x 20 mN x 2 mZ in the area of
closest spaced drilling covering the open pit resource area (1/2 to
1/3 of drill spacing). In areas of more sparse drilling including
most of the underground resource the block size was 60 mE x 60 mN x
6 mZ (1/2 to 1/3 of drill spacing).
10. Grades were estimated using Ordinary Kriging of 2m downhole
composites, no grade capping was deemed necessary. An incrementally
larger search radius of 100, 200 and 300 m was used. The maximum
number of samples per search was restricted to 18 maximum and
samples per drillhole restricted to 2 in the area of 2 mZ blocks,
elsewhere there was no restriction in the number of samples per
drillhole. Discretisation was 5x5x2. The estimate was completed
using Micromine 2023.1 software.
11. Mineralisation ranges from approximately 30 to 160m below
surface in the open pit resource and is approximately 550m along
strike to the southwest and 150m down dip to the northeast.
Elsewhere the resource ranges up to 250 to 300m below surface with
an additional strike length of 1200m extending down dip 300 to
500m.
12. The mineral resource is closed off by drilling and as it
nears surface to the northwest and southwest. Down dip to the
northeast mineralisation may continue and it has been extrapolated
by 50m from the edge of drilling, were further mineralisation to be
present here it would likely only be amenable to underground mining
due to the high stripping ratios to the northeast. To the southeast
where the deposit is deepest further mineralisation has been
identified at depths 250-300m, however drilling is too sparse to
infer continuity and allow reporting of a mineral resource.
