The focus of the study was an eastern zone of Jurassic volcano-sedimentary rock intruded by the Cretaceous coastal batholith, and similar rocks to the west displaying development of extensive hornfels alteration. The eastern area was considered prospective for IOCG (iron oxide copper gold) style mineralisation. The areas were separated by a north-south fault with interpreted downthrow to the west with the IOCG zone being considered as a higher emplaced, more distal expression of potential porphyry mineralisation to the east (Figure 2).

The study identified significant drill targets with some limited surface exposure confirming copper mineralisation.

Drill permitting was submitted in May and is expected to be approved in 4Q 2024.

Ilo Este Project

Significant progress has been made at Ilo Este with the analysis of results from a drone magnetometry survey completed in December 2023. This survey focused on the eastern extension of the Ilo Este licences (Figures 1 & 3), with data acquisition at an average altitude of 35m and a rate of 25 readings per second at a ground velocity of 10m/second. Safety and quality control measures included maintaining a 200m distance from high-tension powerlines in the southeast2.

The survey area is flanked by the regional Chololo fault to the northwest and characterised by the accumulation of quaternary sediments in a SW-NE trending structural corridor. The drone survey was a direct follow-up of the survey in the permit Solis Ilo Este I, with the projected continuation of the magnetic anomaly leading to the recent application of permit Solis Ilo Este II.

Fathom Geophysics of the USA have subsequently analysed and combined 2014 ground magnetometry data with the 2023 drone magnetometry results, revealing potential alteration associated with magnetite. These findings suggest potential extensions of the magnetite alteration associated with porphyry-style mineralisation encountered at Ilo Este, extending east across the Chololo regional fault.

In the primary advanced target area at Ilo Este environmental monitoring programs are currently underway in support of the drill permit applications, which are in progress. Drilling is anticipated in Q1 2025, subject to receipt of necessary permits.

Cinto Project

Subsequent to the end of the Quarter, the Company completed a first pass geochemical programme at its Cinto Project. The programme identified high grade samples up to 7.14% copper with mineralisation mapped over a 200m x 100m area in historical workings associated with significant alteration and structural deformation3,4.

Initial mapping programmes identified a zone within and bordering the Incapuquio Fault system that showed the presence of abundant copper oxides through artisanal workings (Figures 4 & 5). The zone, approximately 200 x 100m in extent, consisted of shales and tuffs with argillic and propylitic alteration showing considerable multi-directional faulting and brecciation with copper oxides occurring in distinct patches3,4.

Several assays returned copper values greater than 1% and one high grade sample returned 7.14% Cu in a highly mineralised oxide zone4. Some mineralised structures were at high angles to a bounding splay of the Incapuquio fault to the north. The nature of the occurrence (mineralisation breccias, abundant copper oxide mineralisation in places) suggest a proximal source. Geochemical assay results (associated Ag, Au, Mo and zinc) have reflected a chemistry similar to the neighbouring Toquepala deposit. The copper occurrences are considered by management as a marker for a potential porphyry style mineralisation in the area.

The Company has already received and approved a proposal for first drone magnetometry survey which is programmed to commence in the last week of August directly following the completion of the Guaneros drone magnetometry survey commencing in week one of August, this initial survey may be followed up with a ground IP programme to assist in target development and initial drill hole design. EIA drill permitting submission will follow immediately upon the completion of the initial geophysical programmes with approximately 4-5 months required for permitting approval.

Guaneros Project

The 6,400 hectare Guaneros project is located between the Company's Chancho al Palo (Ilo Norte) and Ilo Este Projects (Figure 1) and has been subject to minimal systematic exploration by previous owners. During the Quarter, Solis' geologists identified alteration and outcropping copper mineralisation in the new applications, approximately 8km north-west along strike from, and in a similar geological setting to, known porphyry-style mineralisation at Ilo Este. As announced on 10 May 2024, the Company is undertaking assays on two hand specimens from Guaneros and results are expected in due course. Collation of samples for analysis has led to a longer than expected assay turnaround time.

Subsequent to the end of the Quarter5, a drone magnetometer survey (Figure 6) has been contracted and will commence in early August. This survey will be the first targeting exercise and assist in the identification of areas for follow up geochemical and geophysical surveys and the submission of the first EIA for drill permitting. Mapping crews have been mobilised to site to systematically cover the tenement package in order to contribute an evaluation of drill targets.

Acquisition of the additional land at Guaneros has supported the Company's strategy in building a compelling portfolio of exploration properties in an underexplored porphyry belt.

BRAZIL LITHIUM PROJECTS

Borborema

A total of 843 geochemical soil samples were taken across three tenements on a 200m x 100m grid spacing in the northeastern portion of the Borborema project during April (Figure 7). The objective of the programme, in conjunction with field mapping and reconnaissance, was to identify potential lithium bearing pegmatite systems within previously unexplored terrain.

585 assay results were reported, with no material results recorded for lithium suite minerals, base or precious metals. The decision to halt further expenditure on geochemical sampling at Borborema was subsequently made until all tenements are mapped and priority target areas identified.

Approximately 270 assays are pending from the initial geochemical programme at Borborema with anomalous areas of mineralisation expected to be followed up with additional sampling once assays received. No further exploration activities have been carried out in the Borborema district during the last Quarter.

PROJECT GENERATION

Solis is continually reviewing potential acquisitions in various jurisdictions and commodity spaces with the emphasis on copper, gold and lithium projects which are drill ready or with known mineralised systems previously identified.

CORPORATE

The Company has a current cash balance of approximately AUD $4.4 million to advance its portfolio of exploration assets.
