("Future Metals" or the "Company")
Drilling Continues to Confirm Bulk Tonnage Potential at the Panton PGM-Ni Deposit
Future Metals NL ("Future Metals" or the "Company", ASX|AIM: FME), a platinum
group metals ("PGM") focused company, is pleased to report shallow, wide PGM
assay results from the resource definition drilling undertaken at its 100%
owned Panton PGM Project ("Panton") in northern Western Australia.
Assay results reported in this announcement are from three out of a total of
52 drill holes submitted for assaying, comprising 19 holes drilled by the
Company and 33 historical drill holes not previously sampled. Once received,
assay results from all 52 holes will support the modelling of a new bulk
tonnage, shallow JORC Mineral Resource Estimate ("MRE") for Panton. Panton has
a current JORC MRE of 14.32Mt @ 4.89g/t PGM(6E) and 0.31g/t gold for 2.4Moz of
contained PGM and gold (refer to Appendix One).
Highlights
§ Assay results received for three exploration holes, further to the eight
metallurgical hole results previously reported in the Company's announcement
of 17 January 2022, included (refer to Table One and Appendix Two for full
details):
o 18.27m @ 1.95g/t PdEq (1.58 g/t PGM3E & 0.20% Ni) from 74m (PS394)
o 16m @ 1.56g/t PdEq (1.17 g/t PGM3E & 0.19% Ni) from 23m (PS395)

§ Assay results pending for a further 49 drill holes comprising 16 holes
recently drilled by the Company and 33 historical drill holes that were not
previously sampled through the footwall of the Upper Reef
§ Once the remaining assay results have been received, the Company will
incorporate the new results into an updated MRE that will encompass shallow,
bulk PGM-Ni mineralisation up to 20-40 metres in thickness, that importantly
sits outside of the current MRE (refer to the Company's announcement of 8
December 2021 and Figures Two and Three)
§ Metallurgical flotation test work is underway on both high-grade and
low-grade representative composite samples from the previously reported
metallurgical holes
§ The Company remains in a strong financial position, with cash at bank of
A$5.6 million as at 31 December 2021
Recently appointed CEO, Mr Jardee Kininmonth, commented:
"The results from these latest drill holes confirm the potential for
substantially greater widths of shallow PGM mineralisation than modelled in
the current MRE and demonstrate the growth potential of the 100% owned Panton
PGM deposit. We look forward to reporting further drill results regularly over
the next 2-3 months as assays are received for the remaining 49 drill holes."

Exploration Drillhole Assay Results
A total of 19 resource definition holes were drilled as part of the Company's
6,000m diamond core drilling programme. Additionally, the Company sampled core
from 33 historical diamond drill holes to support the modelling of an updated
MRE based on the bulk tonnage mineralisation at Panton.
Assay results for the initial three of the 19 resource definition holes
drilled (PS393 - PS395) have now been received and confirm much broader widths
of shallow PGM mineralisation than modelled in the current 2.4Moz MRE (refer
to Appendix One). Assay results from these initial three holes are set out
in Table One below (refer to Appendix Two for the drill hole details):

Drilling Programme Overview
As previously reported, the Company has completed approximately 6,000m of
diamond core drilling designed to:
§ provide samples for further metallurgical test work;
§ test continuity and depth extensions to the existing MRE;
§ test the potential for defining a much larger and shallower
mineralised zone at lower cut-off grades; and
§ test parallel zones of highly anomalous PGM at surface (i.e. the
Northern Anomaly)
The Company has completed 27 drill holes to date. Eight holes were drilled to
provide metallurgical samples as announced on 28 October 2021 and 17 January
2022. Assay results from the first three of the 19 resource definition holes
drilled are reported in this update. Assay results from the remaining 16
resource definition holes remain pending with samples submitted to Bureau
Veritas in Perth, Western Australia in 11 batches between October 2021 and
January 2022.
Historical drill holes were often terminated once the hole reached the 'Upper
Reef' or the 'Middle Reef' and were not drilled through the entire prospective
footwall horizon to the 'Lower Reef' (refer to the Company's announcement of 8
December 2021). Furthermore, several historical drill holes only had samples
and assays taken within the visible chromitite in the Upper and Middle Reef
and were not sampled between or below in the host dunite rock.
The Company sampled partially unassayed historical holes that were drilled
into the mineralised footwall dunite. A total of 33 historical drill holes
that were not previously completely assayed have now been sampled and
submitted for assaying in December 2021 and January 2022.
The Company expects to progressively report assay results from a further 49
drill holes (comprising the 16 recently drilled holes not yet reported and 33
historical holes) over the next 2-3 months. Results will be reported regularly
throughout the remainder of Q1, 2022 and into early Q2, 2022.
Once received, all new assay data will be incorporated into a new MRE for the
Panton PGM Project. The planned updated MRE will take into consideration
shallow, bulk PGM-Ni mineralisation of up to 20-40 metres in thickness that
sits outside of the current MRE (refer to the Company's announcement of 8
December 2021).
Palladium Equivalent (PdEq)
Based on metallurgical test work completed on Panton samples, all quoted
elements included in the metal equivalent calculation (palladium, platinum,
gold, nickel, copper and cobalt) have a reasonable potential of being
ultimately recovered and sold.
Metal recoveries used in the palladium equivalent (PdEq) calculations are in
the midpoint of the range of recoveries for each element based on
metallurgical test work undertaken to date at Panton. It should be noted that
palladium and platinum grades reported in this announcement are lower than the
palladium and platinum grades of samples that were subject to metallurgical
test work (grades of other elements are similar).
Metal recoveries used in the palladium equivalent calculations are shown
below:
§ Palladium 80%, Platinum 80%, Gold 70%, Nickel 45%, Copper 67.5%
and Cobalt 60%
Metal prices used are also shown below:
§ Palladium US$1,700/oz, Platinum US$1,300/oz, Gold US$1,700/oz,
Nickel US$18,500/t, Copper US$9,000/t and Cobalt US$60,000/t
Metal equivalents were calculated according to the follow formula:
§ PdEq (Palladium Equivalent g/t) = Pd(g/t) + 0.76471 x Pt(g/t) +
0.875 x Au(g/t) +1.90394 x Ni(%) + 1.38936 x Cu(%) + 8.23 x Co(%)

About Panton PGM Project
The 100% owned Panton PGM project is located 60 kilometres north of the town
of Halls Creek in the eastern Kimberly region of Western Australia, a tier one
mining jurisdiction. The project is located on three granted mining licences
and situated just 1 kilometre off the Great North Highway which accesses the
Port of Wyndham (refer to Figure Four).
The Panton PGM Project has a JORC Mineral Resource estimate of 14.32Mt @
4.89g/t PGM, 0.31g/t Au and 0.27% Ni (refer to Appendix One).
The Panton mineralisation occurs within a layered, differentiated
mafic-ultramafic intrusion referred to as the Panton intrusive which is a 10km
long and 3km wide, south-west plunging synclinal intrusion. PGM mineralisation
is hosted within two stratiform chromite reefs, the Upper and Middle reefs,
within the ultramafic sequence.

About Platinum Group Metals (PGMs)
PGMs are a group of six precious metals being Platinum (Pt), palladium (Pd),
iridium (Ir), osmium (Os), rhodium (Rh), and ruthenium (Ru). Exceptionally
rare, they have similar physical and chemical properties and tend to occur, in
varying proportions, together in the same geological deposit. The usefulness
of PGMs is determined by their unique and specific shared chemical and
physical properties.
PGMs have many desirable properties and as such have a wide variety of
applications. Most notably, they are used as auto-catalysts (pollution control
devices for ICE vehicles), but are also used in jewellery, electronics,
hydrogen production / purification and in hydrogen fuel cells. The unique
properties of PGMs help convert harmful exhaust pollutant emissions to
harmless compounds, improving air quality and thereby enhancing health and
wellbeing.

Exploration done by other parties § Acknowledgment and appraisal of exploration by other parties. § The Panton deposit was discovered by the Geological Survey of Western
Australia from surface mapping conducted in the early 1960s.
§ Pickland Mather and Co. drilled the first hole to test the
mafic-ultramafic complex in 1970, followed by Minsaco Resources which drilled
30 diamond holes between 1976 and 1987.
§ In 1989, Pancontinental Mining Limited and Degussa Exploration drilled a
further 32 drill holes and defined a non-JORC compliant resource.
§ Platinum Australia Ltd acquired the project in 2000 and conducted the
majority of the drilling, comprising 166 holes for 34,410 metres, leading to
the delineation of a maiden JORC Mineral Resource Estimate.
§ Panoramic Resources Ltd subsequently purchased the Panton PGM Project
from Platinum Australia Ltd in May 2012 and conducted a wide range of
metallurgical test work programmes on the Panton ore.
Geology § Deposit type, geological setting and style of mineralisation. § The Panton intrusive is a layered, differentiated mafic to ultramafic
body that has been intruded into the sediments of the Proterozoic Lamboo
Complex in the Kimberley Region of Western Australia. The Panton intrusion
has undergone several folding and faulting events that have resulted in a
south westerly plunging synclinal structure some 10km long and 3km wide.
§ PGM mineralisation is associated with several thin cumulate Chromitite
reefs within the ultramafic sequence. In all there are three chromite
horizons, the Upper group Chromitite (situated within the upper gabbroic
sequence), the Middle group Chromitite (situated in the upper portion of the
ultramafic cumulate sequence) and the Lower group Chromitite (situated toward
the base of the ultramafic cumulate sequence). The top reef mineralised zone
has been mapped over approximately 12km.

o easting and northing of the drill hole collar
o elevation or RL (Reduced Level elevation above sea level in metres) of
the drill hole collar
o dip and azimuth of the hole
o down hole length and interception depth

information is not Material and this exclusion does not detract from the
understanding of the report, the Competent Person should clearly explain why
this is the case.
