Copper and Cobalt Operations Update

Jubilee, the AIM and Altx traded metals processing company is pleased to announce key milestones
achieved in its southern copper and cobalt operations in Zambia. The Company’s cobalt operation, at
its Sable Refinery (“Sable”), has successfully achieved the production of export grade cobalt product
allowing the ramp-up of its operations to commence.

Sable has also successfully commissioned the direct leaching and refining of copper sulphide material
in addition to the recovery and refining of its copper oxide concentrates. In doing so, it has successfully
bypassed the traditional power intensive, smelting process used by the industry for the refining of
copper sulphide materials, significantly expanding Sable’s processing capability.

Highlights

    •   Jubilee achieved export quality cobalt production, allowing the commencement of the ramp-up
        of operations
    •   The Company will initially target the production of 50 tonnes of contained cobalt metal which
        is the equivalent of approximately 220 tonnes of final product, before ramping up to the 1 200
        tonnes of contained cobalt metal annual capacity, which equates to 5 280 tonnes of final
        product
    •   This achievement forms part of the development and design of the much larger Northern
        Refining Project
    •   The cobalt, seen as a by-product to the Southern Refining operations, holds the potential to
        significantly contribute to overall earnings with targeted margins at capacity expected to exceed
        45% and first sale of product targeted to commence end of December 2022
    •   Direct leaching of copper sulphide from mixed copper concentrates achieved at operational
        scale on a sustainable basis, resulting in improved recoveries on overall copper treated.
        This process by-passes the need for traditional power intensive smelting of copper sulphide
        concentrates, offering additional growth opportunities from Sable’s operational capability from
        the processing of mixed copper oxide and copper sulphide concentrates

Following its first production of export quality cobalt carbonate, Sable is now able to commence with
the commercial production of cobalt targeting an initial production rate of 50 tonnes per month of
contained cobalt metal for the next three months, thereafter, stepping up to targeted capacity of 100
tonnes per month.

The cobalt production is expected to make a significant contribution to the earnings potential of the
Southern Copper refining operations with margins expected to exceed 45% at capacity. This establishes
Sable as one of the few cobalt refineries in Zambia able to process and refine cobalt containing materials
at commercial scale.
Sable has also successfully achieved the direct leaching of copper sulphide from mixed copper
concentrates at operational scale. This leading refining approach offers further diversity to its
operational capability to target mixed copper oxide and copper sulphide concentrates which Jubilee has
identified as a significant growth opportunity.

In its integrated annual report, Jubilee noted the water and power infrastructure challenges present in
Zambia and the constraints these have had on the newly commissioned Roan concentrator. The water
constraints will be addressed with the upgrading of the water infrastructure commencing the first week
of December. This follows the award of a water licence to Roan allowing it to own and operate a
dedicated water supply infrastructure for its operations. The intervention project is expected to be
completed over 6 days during which time the water infrastructure will be upgraded and
recommissioned. The power constraints experienced at Roan have been resolved satisfactorily.

Leon Coetzer, CEO commented: “Jubilee’s Project Roan is part of our Southern Copper Refining Strategy
(“the South”), and the predominant supplier of concentrates, produced from perceived waste to the
Company’s copper and cobalt Sable Refinery, which is adjacent to Jubilee’s Kabwe tailings resource in
Zambia.

“The success and the lessons learned from the South are fundamental to the development and de-risking
of Jubilee’s Northern Refining Strategy (“the North”) where we will implement the same strategy, but at
scale.

“With approximately 264 million tonnes of copper-containing surface tailings secured in the North, the
focus is now on integrating the successful technology of the Sable plant at a much larger scale into the
North.

“With such a large resource secured, the North offers the potential to far exceed the original stated
Production target of 15 000 tonnes per annum of copper. A key next decision for the implementation of
the North is to lock in the capacity of the North refinery which sets in motion the final design capacities
for the concentrators that supplies the refinery with concentrated copper and concentrate materials.

“With the now proven processes in the South, the Company expects to receive the final recommendation
on capacities from its design teams by mid-January 2023. I look forward to updating shareholders in this
regard.”
