Pinderi Hills Project Update

Alien's Joint Venture Partner Identifies 6km2 Li2O Soil Footprint at Pinderi Hills

Alien Metals Ltd (AIM: UFO) is pleased to provide an update covering recent activities and exploration works completed and assessed by Errawarra Resources Ltd ("Errawarra") at its 100% owned Pinderi Hills silver and precious metals project (the "Project" or "Pinderi Hills") in Western Australia.

As announced on 29 April 2024, Errawarra entered into a joint venture agreement with Alien in respect of the lithium rights of the Project (the "JV"). Recent results provided by Errawarra concerning exploration for lithium at the Pinderi Hills Project have confirmed that the Munni Munni Mafic Complex is highly prospective for PGE's, nickel and copper. As part of the terms of the JV, Errawarra has a first right of refusal to acquire all the remaining mineral rights to the Pinderi Hills nickel, copper, and platinum group metals projects.

Highlights:

Results from over 1,000 samples collected at Pinderi Hills were received

• Reconnaissance samples from Pinderi Hills Project confirm lithium pegmatite potential
• New large lithium soil footprint identified within 6km2 area
• Lithium trends with up to 3km strike highlighted by anomalous soil and stream samples
• Second anomalous lithium area highlighted by stream samples
• Rock chip sample reports 288ppm Li2O with associated anomalous Cs, Ta and Nb
• Follow-up planning underway

Munni Munni Anomaly:

The results of reconnaissance samples comprising soil (926 samples), stream sediment (190 samples) and rock chip (37 samples) undertaken on the Pinderi Hills JV tenements have been received and assessed. The stream samples covered the entire tenement package while the soil samples were restricted to the area covered by tenements M47/123, 124, 125 and 126 and a portion of E47/3322. Rock chip samples were taken when a pegmatite was identified while undertaking the soil and stream sediment sampling programmes.

The soil samples which were taken on a 400m x 100m north-south orientated grid have highlighted several closely related linear anomalous Li2O trends within a 6km2 footprint. These trends are highly suggestive of lithium bearing pegmatites due to the linear and swarm characteristics of the anomalies. Although preliminary limited on ground investigations have not identified a cause for the anomalous sample results, a pegmatite rock chip sample located within the anomalous zone has reported 73 ppm Li2O. The stream sediment samples associated with the lithium soil anomalism in this area have also reported anomalous Li2O

values which complements the soil results and further highlights the prospectivity of this area within the project tenements.

Maitland Lithium Anomaly:

Three spatially related stream sediment samples located on the margin of the Maitland Mafic Intrusion and 10km northeast of the Munni Munni lithium anomaly have also reported Li2O greater than 50ppm Li2O (Figure 1). This result is anomalous for the streams in this region and follow-up of this anomalous area by further stream sediment or soil samples is to be undertaken.

Anomalous Rock Chip Sample:

A sample from possible pegmatite located 6km due east of the Munni Munni lithium anomaly has reported 288ppm Li2O along with associated elevated Cs, Ta and Nb which is characteristic of a LCT pegmatite. Follow-up of this anomalous rock chip sample will be a priority.

Next steps:

The first pass sampling program which covered the entire tenement package of 175 km2 has provided encouraging results and confirmed the lithium fertility of the JV tenements. Follow-up work programs will initially focus on resolving the larger Munni Munni lithium soil trends as well as following-up the Maitland anomalous lithium stream anomaly and the isolated anomalous lithium pegmatite sample that reported 288 ppm Li2O and associated pathfinder elements.

Robert Mosig, Non-Executive Director, commented:

"This is a pleasing start to the exploration programmes at Pinderi Hills. Errawarra is a valued joint venture partner and we look forward to further positive lithium exploration results as the work programmes are implemented.

"Importantly, the data being gathered by Errawarra, at no cost to Alien, will continue to provide the Company essential information that will assist in the analysis and drill targeting for silver, base and precious metals."
