Zigzag Drilling Results

First Class Metals PLC ("First Class Metals" "FCM" or the "Company") the UK listed metals exploration company seeking economic metal discoveries across its extensive Canadian Schreiber-Hemlo, Sunbeam and Zigzag land holdings is delighted to announce the results of an inaugural drilling programme on the Company's Zigzag Property, (the "Property") located in the Seymour-Falcon corridor in northwestern Ontario, Canada.

HIGHLIGHTS

• Assay results from the recent drill programme are in line with and exceed the channel sample results.

Selected highlights include:

o ZIG-23-01 4.3m @ 1.65% Lithium (Li20) including 1m at 2.93%

o ZIG-23-02 5.0m @ 1.5% Li20 including 0.2m @ 5.19% and 5.75m @ 0.21% Rb20

o ZIG-23-07 6.5m @ 1.09% Li20 including 0.5m @ 2.76%

• Elevated grades of several key technology critical metals present including: gallium (Ga), rubidium (Rb20) , caesium (Ca) and tantalum (Ta).
• Significant upside for the expansion of the geochemical envelope along strike in both directions and down dip.
• Initial geochemical results indicate the probable existence of a second structure.
• An Exploration Permit to allow additional stripping and drilling on the Property is being drafted.

Marc J Sale Chief Executive Officer Commented- "The results from our first drill programme at Zigzag are first class and have not only confirmed our belief in the potential of the 'core zone', but have also significantly exceeded our expectations for the Property. The associated critical metals identified have added another dimension to the Property's potential. Obviously more work is required specifically along strike and further exploration of the southern structure, hence we are to initiate discussion regarding a new Exploration Permit.

Zigzag is growing as a significant lithium and critical metal play in this rapidly emerging pegmatite district."

A focussed drill programme of under 500m in 10 NQ diamond drillholes was completed in late December and all the geochemical assay results are now available. Nine of the holes were targeted at the pegmatite with two 'step-back' holes and a 10th being drilled as a scissor. All targeted holes successfully intersected the pegmatite.

The drilling has vindicated the channel sampling as well as extended the geochemical and geological knowledge of the structure hosting the pegmatite, (see Map 1). The most easterly and westerly holes indicate the structure remains open along strike and importantly the successful step-back holes show the structure continues and remains open at depth.

The Company will now look to initiate the next most appropriate plan of exploration which will be focussed to extend strike and delineate the recently discovered southern structure.

Significant intersections for the drill programme appear in table 1, see below

Table 1 assays from the (nine) hole drill programme at Zigzag, every hole had reportable intersections of Li₂O with significant 'credits' from the accessory critical elements / metals, specifically rubidium oxide, Rb₂O.

The combined geochemical data that the initial grab samples (RNS 31 October 2023), the subsequent channel sampling programme (RNS 28 November 2023) and the recent MMI soil survey (RNS 7 February 2024) support the belief that the 'core 400m zone' contains a significant structure of >1% Li₂O and is open along strike. As previously reported, both the most eastern and western holes of the recent drilling programme intersected pegmatite. The soil sample results further suggest that the mineralisation is open in both directions.

Critical Technology Metals @ Zigzag

While the focus of the project remains on the lithium component, the presence of elevated levels of Rb₂O (peak 0.54% over 0.3m within interval of 5.75m @ 0.21% (2100 g/t) in hole ZIG-23-02), Caesium (peak 480 g/t over 0.45m within interval of 5.00m @ 151 g/t in hole ZIG-23-03), Gallium, and Tantalum (peak 624 g/t over 0.45m within interval of 164g/t over 3.9m in hole ZIG-23-03-03) are potentially a significant 'credit' to the metallurgy of any resource identified.

These speciality metals have been classified as 1 & 2 'Critical Metals' by the USA and Canadian Governments, highlighting their significance usage in modern technology due to their crucial role in various electronic, semi-conductor, and military hardware. Currently China dominates world production and supply of all these elements.

Despite the limited market for specialty metals, it is noteworthy that Rubidium has recently demonstrated a strong price performance, with trading prices exceeding $3100 per ounce on the Shanghai Metals Market3. Recognizing the potential economic benefits and value-added by these specialty technology metals, First Class intends to conduct further investigations into their possibilities and explore their impact on the overall value of the project.
