Molefe Mine Phase 1 Drilling Confirms Continuity of Copper Mineralisation and Extends Mineralised Zone
Jubilee, the Zambia focused copper producer, is pleased to provide an update on the latest drilling
results at the open-pit Molefe copper mine (Molefe Mine), located within trucking distance of the
Company's Sable refinery.
The Phase 1 infill drilling programme has confirmed the continuity of near-surface copper oxide
mineralisation and consistency of grades, supporting the Molefe Mine's expansion program and
Jubilee's strategy of securing high-quality copper feed sources from owned resources to underpin its
growing processing operations in Zambia (Pillar 2 of its Zambian strategy as previously announced).
Highlights
• Infill drilling completed to date confirms copper ore grades consistent with those incorporated
in Molefe Mine's expansion mine plan
• New near surface zone, identified and validated based on visual and handheld pXRF
assessment, extending copper oxide mineralisation by approximately 250 metres beyond the
expansion mine plan with mineralisation remaining open to the east
• Phase 2 drilling program is currently under way by project partner, Galileo Resources Plc
(Galileo), targeting the eastern extension to determine the full extent of the mineralised zone
• Consistency of grades and thicknesses supports confidence in the resource and provides a
strong foundation for the advancement of a formal resource estimate
• Results continue to demonstrate shallow, copper oxide mineralisation suitable for processing
at Jubilee's Sable Refinery
• Infill drilling of oxide mineralisation reinforces projected grades of ore currently incorporated
into the mine plan
• Peak intercepts include the following:
- MNKDD010 16.00m @8.01% TCu ("total copper"), 1.60 % ACu ("acid soluble
copper") from 18.00m (TCu cut off 0.6%, ACu cut off 0.35%)
- MNKDD011 20.0m @5.33% TCu, 0.92% ACu from 22.0m (TCu cut off 0.6%, ACu cut off
0.35%)
- MNKDD012 10.7m @ 6.54% TCu, 2.17% ACu from 37.00m (TCu cut off 0.6%, ACu cut
off 0.35%) from 33.8m
- MNKDD013 6.00m @1.07% AsCu from 79.00 m (TCu cut off 0.6%) from 81.0m
- MNKDD014 6.80m @5.40% TCu, 2.06% ACu from 54.20m (TCu cut off 0.6%) from
54.2m
- MNKDD015 7.50m @ 9.17% TCu, 1.30% ACu from 43.00 m (TCu cut off 0.6%, ACu cut
off 0.35%)
- MNKDD016 2.17m @ 5.40% TCu, 1.80% ACu from 60.83m (TCu cut off 0.6%)
Leon Coetzer, CEO of Jubilee, commented:
"We are very excited by these results, delivered in a few short months, which confirm the apparent
continuation of the high-grade copper reef close to surface that is currently being accessed at the
Molefe Mine operations. The high-grade intersections of shallow copper oxide is perfectly suited for
processing and refining at the nearby Sable refinery.
The extension identified to the eastern boundary provides a strong indication of the further
continuation of the mineralised reef, particularly given the additional approximately 12 300ha of
exploration ground we hold to the east of the 400ha Molefe mining area.
We have commenced phase 2 drilling to further define this eastern extension and the Company will
update the market as results become available.
Results from the phase 2 drilling program will be used to provide a clearer timeline for the release of
a formal resource estimate. The updated expanded mine plan, incorporating the latest drill results and
developed in partnership with Galileo, is expected to be published on the Company's website within
the coming three weeks."
Drilling Results
The Phase 1 drilling programme was designed to confirm the continuity and grade of the oxide
mineralisation within the current mine expansion plan at Molefe Mine.
Results demonstrate consistent near-surface copper oxide mineralisation that is amenable to Jubilee's
existing processing capabilities at its nearby Sable refinery and reinforcing previously projected grades
incorporated into the mine plan. The consistency of grades and thicknesses supports confidence in
the resource and provides a strong foundation for the advancement of a formal resource estimate.
A total of 3,390m of drilling has been completed during the Phase 1 program with drill holes still
pending final assay results.

In addition, drilling has identified an extension of copper oxide mineralisation of approximately 250
metres to the east of the current mining footprint based on pXRF assessment. The Phase 2 drilling
program is targeting this newly identified zone extending the focus further east up to the property
boundary. Initial visual inspections of the phase 2 drill cores are encouraging supported by on-site XRF
analysis indicating the potential to further expand near-term mining activities.
These developments align Jubilee's broader strategy of unlocking value from Zambia's extensive
copper resources by securing shallow, high-grade oxide material capable of rapid integration into its
expanding processing infrastructure. The Molefe Mine continues to play a key role in increasing the
availability of feed material to support the growth in copper production.
