Future Metals NL ("Future Metals" or the "Company", ASX | AIM: FME) is pleased to announce its Quarterly Activities and Cashflow Report for the Quarter ended 30 June 2023 ("Quarter").

Future Metals is the 100% owner of the Panton PGM-Ni Project ("Panton Project" or "Project"), located 60km north of the town of Halls Creek in the eastern Kimberley region of Western Australia, a tier one mining jurisdiction.

The Project is situated on three granted mining licences and lies 1km off the Great North Highway which accesses the Port of Wyndham (see Figure One).

The Panton Project hosts an independent JORC Code (2012) Mineral Resource Estimate ("MRE"), as announced on 21 June 2022, of 129Mt @ 1.20g/t PGM3E¹, 0.19% Ni, 0.04% Cu and 154ppm Co (1.66g/t PdEq) at a cut-off grade of 0.90g/t PdEq for contained metal of 5.0Moz PGM3E¹, 239kt Ni, 48kt Cu and 20kt Co (6.9Moz PdEq).

The MRE includes a high-grade reef of 25Mt @ 3.57g/t PGM3E¹, 0.24% Ni, 0.07% Cu and 192ppm Co (3.86g/t PdEq) for contained metal of 2.9Moz PGM3E¹, 60kt Ni, 18kt Cu and 5kt Co (3.2Moz PdEq).

PGM-Ni 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 a series of stratiform chromite reefs as well as a surrounding zone of mineralised dunite within the ultramafic package. The Panton intrusive is also highly prospective for Ni- Cu-PGM sulphide mineralisation from multiple magmatic events.

¹ PGM3E = Palladium (Pd) + Platinum (Pt) + Gold (Au)

Mr Jardee Kininmonth, Managing Director of Future Metals, commented on the Quarter:

"Through the June quarter we continued to optimise the flowsheet at Panton, creating a step-change in PGM recoveries, de-risking the flowsheet and improving project economics through leaching of flotation tails, and optimising the flotation regime. Following these improvements, we can now expect to recover approximately 86% of the PGMs from Panton's ore feed and expect to consistently achieve very high concentrate grades of >280g/t PGM3E1.

With its high grade Resource, recoveries and concentrate grades, Panton compares very favourably to analogous operations in the primary PGM producing jurisdiction of South Africa.

Additionally, we progressed a number of prospective nickel sulphide targets outside of the high-grade PGM reef where scout drilling and follow up exploration activities continue."

Operational Activities

Exploration Discussion

Ongoing exploration target generation identified a potential embayment feature on the Panton North tenement (which is subject to a farm-in agreement with Octava Minerals Ltd where the Company has the right to earn a 70% interest) (see Figure Two).

Embayment features can act as 'sulphide traps', providing a confined localised volume in which sulphide rich magma can settle. This untested embayment feature was identified along the northwest intrusion contact in multiple datasets, including magnetics and short wave infra-red imagery.

A geological review of this embayment area suggested a thickening of the Panton Sill. Field reconnaissance in the area confirmed an altered ultramafic product (magnesite) was present in the area which also cross cuts the dunite on the northern contact. Where the magnesite cross cuts the dunite, brecciated veins are present with fragments of ultramafic and sediment. Rock chip samples (see announcement 'Drilling to Commence at Nickel Sulphide Targets' on 4 May 2023) further mapped out the prospective embayment area and were coincident with historical anomalous stream sediment samples (see announcement 'Large Ni-Cu-(PGE) Sulphide Zone Identified at Panton' on 2 February 2023).

Figure Two | Panton and Panton North Exploration Target Areas

Target generation, ground investigation and surface sampling

Geological mapping and sampling was completed along the northern contact of the Panton Sill, including BC1, as well as the Panton West area. The northern contact of the Panton Sill historically has been erroneously mapped; due to topographic constraints and historical tenure boundaries limiting the extent of exploration.

New mapping of the contact confirmed the BC1 embayment feature as well as a smaller, thickened portion to the east, near Panton North. Within this extended basal contact area, averaged pXRF analysis indicated a Ni-Cu anomalous association in the central and eastern portion of the contact with the BC1 area showing a more Ni-S anomalous association. An iron-rich gossan, on the north central most contact of the weathered ultramafic with metasediments, returned averaged X-Ray Fluorescence ("pXRF") readings of 0.22% Co, 0.08% Cu, 0.08% S and 0.01% Ni. This is the same area where weathered rock chips of ultramafic returned multiple anomalous Ni-Cu samples.

At BC1, an ultramafic outcrop of pyroxenite returned pXRF averages of 0.43% Ni, 0.22% S, 0.06% Cu and 0.05% Co.

South of BC1, ground mapping around drill holes PS053 and PS407 identified gossanous material that had been shifted to create historical drilling pads, over a 50m x 40m area. Further exploration of the area has identified weathered sulphides in two ultramafic rock chips with average pXRF values of 1.95% Ni, 0.26% Cu, 0.09% Co, 0.01% S 135m to the northwest of PS053 (BD23-056, see Photo One) and 4.28% Ni, 0.13% Cu, 0.11% Co, 0.01% S that is 70m to the northwest of PS053 all positioned along strike of a northwest fault (BD23-055). BD23-055 was collected from rock which had been disturbed from historical clearing. This is the same structure that is interpreted to host the magmatic sulphide mineralisation in hole PS053. To assist in target generation in key areas, the Company is currently planning a further detailed mapping and rock chip sampling programme to commence in Q3 CY2024.

Drilling

During the Quarter, a c.2,000m RC scout drilling programme commenced at the Panton North Project, starting at the BC1 Prospect (see Figure Two).

This first pass RC drilling programme was designed to test the BC1 and Panton West Prospects for Ni-Cu-PGM mineralisation. The prospectivity of these targets is supported by detailed analysis performed on information across EM, magnetics, gravity, stream sediments, soil samples, rock chip samples, and validation in the field.

The BC1 Prospect drilling was designed to test the newly interpreted basal contact for the Panton Sill, which is supported by EM and magnetic anomalies. Drilling at the Panton West Prospect targeting discrete magnetic features coincident with historical EM anomalism at depth, with these features located on the contact of a gravity high interpreted to be an ultramafic intrusion under cover. Neither of these targets have been previously drilled.

The Company was successful in securing EIS co-funding of A$147,000 from the Western Australian State Government to co-fund drilling at the Panton West Prospect.

Initial scout drilling at BC1 and Panton West has been completed with assay results expected to be announced in due course.

Metallurgical Testwork and Scoping Study Activities

Processing and Project Delivery Strategy

The Company continues to methodically de-risk the development of Panton and enhance project economics through ongoing metallurgical testwork and optimisation.

A series of improvements are being incorporated into the Scoping Study further demonstrating the viability of the Panton Project as a low capital, high-grade and high recovery operation producing PGMs, nickel and chromite concentrate.

The Scoping Study is evaluating multiple pathways (see Figure Three) for progressing Panton, assessing both concentrate production for sale into the smelting market, and downstream integration to produce high payability, low emission upgraded metal products for direct sale to end users.

These de-risking factors include:

§ Ore sorting testwork

Demonstrating the ability to separate high-grade PGM reef with a 97% recovery from the surrounding low grade bulk mineralisation and waste. Enabling the use of more conventional mining methods to extract the high-grade ore and ensure a high-grade feed for the mill, thereby reducing capital and operating costs.

§ Flotation test work

Demonstrating the ability to consistently achieve flotation PGM_3E1 recoveries averaging 78% at a very high average concentrate grade of >280g/t PGM_3E1 utilising conventional crushing, grinding and flotation techniques on high-grade PGM_3E1 reef ore.

§ Flotation tails leaching test work

Leaching of flotation tails improved overall PGM_3E1 recoveries to 93.1% Pd, 76.8% Pt and 94.2% Au (~86% PGM_3E1), requiring no additional grinding, at atmospheric pressure and ambient temperature.

§ Magnetic Separation

Test work demonstrating the ability to produce a saleable chromite concentrate from flotation tailings using magnetic separation.

Figure Three | High-Level Flowsheet

Improved PGM Recoveries Through Leaching of Flotation Tails

The Company demonstrated that cyanide leaching of flotation tails at an ambient temperature and atmospheric pressure can achieve recoveries of 83.5% Pd and 92% Au as shown in Table 1.

The positive leaching results not only potentially improve project economics, but also substantially de-risk the flow sheet by providing an additional method of metal recovery following flotation, thereby providing protection from any periods of fluctuating flotation performance.

Pt (g/t)		Pd (g/t)	Au (g/t)
Head Grade	0.94	1.25	0.16
Recovery (%)	0.3	83.5	91.6

Applying previously reported concentrate flotation recoveries in combination with this successful flotation tailings leaching test work provides an overall net recovery of 86% PGM3E1 as show below in Table 2.

Flotation Reagent Optimisation

The Company has continued to optimise its flotation test work subsequent to demonstrating the ability to consistently achieve a high-grade concentrate at high recoveries.

As part of this work, the Company demonstrated the ability to achieve strong results with 79.4% PGM3E1 recovery at a concentrate grade of 309g/t PGM3E1 without the need for nitrogen sparging, thereby reducing the capital and operating costs and simplifying the flow sheet.

A summary of the results from this reagent optimisation testwork is shown in Table 3 below.

Chromite Concentrate as a Valuable By-Product

Test work has demonstrated the ability to produce a saleable chromite concentrate from flotation tailings through a magnetic separation circuit.

Chromite concentrate is a high-value bulk product primarily used for the production of ferrochrome, a non-substitutable input into the production of stainless steel. The major suppliers of chromite concentrate include South Africa, Turkey, Zimbabwe & Albania. Given its importance to the steel industry and the limited deposits in Western jurisdictions it is listed as a critical mineral in the United States, Australia, Japan and India.

The Company has commenced further optimisation test work and will assess the inclusion of a chromite concentrate circuit as part of the Project's flow sheet in the Scoping Study. Chromite concentrate has the potential to be a valuable by-product and reduce tailings at site.

June 2023 Quarter Activities

Ongoing Exploration Activities

The Company is progressing its nickel sulphide exploration model including completing scout drilling of two priority targets being BC1 and Panton West. The Company will provide an update on planned forward activities once assays are received and interpreted through Q3 CY2023.

Scoping Study Progress

The Company continues to methodically de-risk the development of Panton and enhance project economics through ongoing metallurgical test work and optimisation. This series of improvements to the Scoping Study, targeted for completion in Q4 2023, will serve to demonstrate a credible path towards developing a future low capital, high grade PGM-Ni operation.

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.
