Exploration Results from Coola Exploration Licence

 

Pensana is very pleased to report on the results from the recently completed
exploration programme on the Coola Exploration Licence located 40 kilometres
north of Longonjo.

Exploration activities have been focused on three highly prospective targets
namely the Sulima West carbonatite, the Benge Novo alkaline complex and the
Coola carbonatite.

The results from Sulima West are considered to be a significant discovery and
will be the main focus of exploration activities in 2023.

Highlights include:

·  Trench sampling at Sulima West carbonatite reported rare earth grades of
up to 9.7% Total Rare Earth Oxides ("TREO"), averaging 3.4% TREO over 68
metres at surface. Individual samples from other trenches reported grades
between 3.4 and 5.2% TREO.

·  Pit sampling at Sulima West carbonatite reported rare earth grades of up
to 5.2% TREO, averaging 4.3% TREO over 6 metres at surface.

·  Manganese grades in the laterite at Sulima West were reported from 1.5%
to 18% Manganese Oxide ("MO"), averaging 12% MnO all at surface and are
regarded as economically significant.

· Geological mapping at Sulima West identified a prominent outcrop of
supergene apatite occurring together with maghemite and monazite and the area
has the potential to host significant phosphate resources. The style of
mineralisation has similarities to the Mt Weld deposit currently being mined
in Western Australia by Lynas Corporation.

·  Reconnaissance mapping of the Benga Novo intrusion, immediately to the
north of Sulima West carbonatite, indicates a large almost 10 km alkaline
intrusion largely covered by residual soils. Reconnaissance mapping indicates
potential for bauxite deposits, ionic clay type Rare Earth Element ("REE")
deposits and direct application fertilizers.

Exploration Manager, Grant Hayward, commented:

"We are extremely excited with the trench and pit analytical results from
Sulima West laterised carbonatite which have reported high rare earth grades
over significant widths at surface. Together with the presence of abundant
apatite and manganese, we regard Sulima West as a significant discovery and it
will be the main focus of our exploration activities in 2023.

The deeply weathered soils overlying the vast Benge Novo intrusion appear to
have the potential for ionic clay hosted rare earth mineralisation in addition
to bauxite deposits and potassic rock fertilizers. Geophysical surveys of all
targets are scheduled for early 2023 and diamond drilling is scheduled to be
initiated on the Sulima West and Coola targets by mid-2023."

 

Sulima West nepheline syenite and carbonatite complex

·  Significant rare earth elements (TREO), phosphate (P) and manganese (Mn)
mineralization have been identified at Sulima West.

·  One of the five historic trenches at Sulima West, excavated in the
1970's by the colonial era Compania Minerais do Lobito prospecting for
radiometric anomalies, was cleaned and sampled at 2-meter intervals across the
iron/manganese ("Fe/Mn") enriched lateritised regolith. Analysis returned
values of between 0.3 and 9.7% TREO, with an average grade of 3.4% TREO over
68 meters at surface.

·   A historic pit at Sulima West and adjacent to Trench 1, was cleaned and
sampled at 1-meter intervals. Analytical results (ICP-MS)returned values of
between 3.4% and 5.2% TREO, with an average grade of 4.3% TREO over 6 meters.

·   Five additional Fe/Mn laterite samples from the other trenches reported
individual values which vary from 4.5% to 7.6% TREO.

·  Reported manganese grades in the laterite range from 1.5% to 18% MnO and
average 12% MnO at surface. The manganese component is regarded to be
economically significant.

·   Samples of the Fe/Mn laterite have been collected for Mineral
Liberation Analysis.

·   The presence of outcrops of secondary, supergene apatite occurring
together with maghemite and monazite at Sulima West attests to the formation
of a zone of phosphate enrichment which must occur within a deeply weathered
regolith. Similar zones of apatite enrichment are noted at Mabounie in Gabon,
Catalão 2 in Brazil and Mt Weld in Australia.

·   Samples of the apatite/maghemite/monazite rock have been collected for
Mineral Liberation Analysis.

Geophysical surveying and diamond drilling of this target is scheduled for Q2
2023 to ascertain the extent of the underlying carbonatite, but importantly
also to quantify the presence and amount of apatite, TREO and manganese.

Benge Novo alkaline complex

·   The Benge Novo intrusion is interpreted as a very large caldera
occurring to the north of the Sulima, Sulima West and Monte Verde intrusions.
It is regarded to be at least 10 km across and is characterised by flat,
deeply weathered soils with a solitary alkaline granite outcropping in the
south eastern area.

·   The discovery of thick, leached and clay rich lateritised material
above the western parts of the known alkaline silicate complex of Benge Novo
are strong indications of the possibility of bauxite potential. Similar
occurrences are known in other parts of the world, for example, the Pocos do
Caldas intrusive nepheline syenite in Brazil. Initial sampling has been
completed and assays awaited.

·  The identification of a significant, clay dominated, deeply weathered
regolith over parts of the main Benge Novo intrusion may additionally be
prospective for the occurrence of ionic clay hosted REE deposits.

·   Both Phosphorus and Potassium are enriched in these rock types and the
use of nepheline syenite as well as ultra-potassic rocks as direct application
crushed rock fertilisers has been a success in many parts of the world. Soils
in the sub region are notoriously impoverished in Phosporous and to a lesser
degree Potassium, two of the three plant macro-nutrients, and further sampling
will be conducted to evaluate the potential for these essential elements.

Airborne geophysical survey of the Benge Novo complex is scheduled for Q2
2023, with a view to guiding exploration of this highly prospective complex.

 

Coola carbonatite

·  Detailed mapping and sampling of the Coola carbonatite has previously
revealed elevated values of TREO over thin soils above outcropping
carbonatite, as well as REE-enriched dolomitic carbonatite which importantly
hosts bastnaesite.

·  Rock chip sampling of the 20-50 m wide portions of the dolomitic
carbonatite ring dyke returned values of between 0.6% and 4.9% TREO (average
2.6%). Soil geochemistry over areas of soil covered dolomitic carbonatite
returned values of between 0.37% and 13.18% TREO (average 3.21%).

·  Samples of the REE mineralized dolomitic carbonatite have been collected
for Mineral Liberation Analysis.

· Auger drilling of the soil covered central caldera, aimed at testing the
potential for near surface supergene mineralisation, was previously
unsuccessful as the auger was unable to penetrate a hardpan ferricrete
developed below the colluvial soils. Deeper drilling is scheduled for 2023 to
effectively test this target.

About Pensana Plc

The electrification of motive power is the most important part of the energy
transition if we are to tackle climate change and one of the biggest energy
transitions in history. Magnet metal rare earths are central to that
transition, forming a critical part of the technology for efficient electric
vehicle motors and offshore wind turbines.

Pensana plans to establish its Saltend processing hub as an independent and
sustainable supplier of the key rare earth magnet metal oxides to a market
which is currently dominated by China.

The US$195 million Saltend facility is being designed to produce circa 12,500
tonnes per annum of rare earth products, of which 4,500 tonnes will be
neodymium and praseodymium oxide (NdPrO), representing over 5% of the world
market in 2025.

Pensana's plug-and-play facility is located within the world-class Saltend
Chemicals Park, a cluster of leading chemicals and renewable energy businesses
in the Humber Freeport and will create over 500 jobs during construction and
over 125 direct jobs once in production.

Powered by low-carbon offshore wind, it will be the first major separation
facility to be established in over a decade and will become one of the few
major producers located outside China.

Feedstock will be shipped as a clean, high purity mixed rare earth sulphate
(MRES) from the Company's Longonjo low-impact operations in Angola. The mine's
state-of-the-art concentrator and proprietary MRES processing plant are
designed by Wood to the highest international standards.

The operations will be powered by renewable energy from hydroelectric power
and connected to the Port of Lobito by the recently upgraded Benguela railway
line.

Pensana believes that provenance of critical rare earth materials supply, life
cycle analysis and GHG Scope 1, 2 and 3 emissions will all become significant
factors in supply chains for major customers.

The Company intends to offer customers an independently and sustainably
sourced supply of the metal oxides and carbonates of increasing importance to
a range of applications central to addressing the energy transition.

Pensana is also aiming to establish Saltend as an attractive alternative to
mining houses that may otherwise be limited to selling their products to
China, having designed the facility to be easily adapted to cater for a range
of rare earth feedstocks.
