Solis Minerals Encounters Copper Mineralisation Encountered During Reconnaissance at Canyon Project

HIGHLIGHTS

• Widespread copper oxide mineralisation confirmed in initial reconnaissance sampling at Canyon Project, with copper occurrences in road-cuts over 400m.
• Rock grab samples returned assays of 0.74% Cu/ 0.07% Mo, and 0.53% Cu/ 0.02% Mo.
• Associated high molybdenum values indicate primary porphyry style mineralisation.
• Follow-up remote sensing, mapping, and rock geochemistry planned at the Canyon Project to quickly focus in on prospective targets over 25km strike length and parallel corridors.
• Solis is advancing its portfolio of targets in the Coastal Belt of Peru with targeted drilling programs across multiple copper projects planned from Q1 2025.

West Leederville, Western Australia--(Newsfile Corp. - November 12, 2024) - Latin American focused copper-gold explorer, Solis Minerals Limited (ASX: SLM) ("Solis" or the "Company") is pleased to announce an update on exploration activities at the Canyon Project in Peru.

Initial reconnaissance activities have commenced at the Canyon Project with sampling confirming the presence of copper oxide mineralisation. The mineralisation was found in joints and faults in road-cuts over a distance of approximately 400m in discontinuous patches.

Two samples returned high values of copper and molybdenum, indicating a porphyry-style mineralisation. Some quartz-veining and alteration were also observed in porphyritic quartz granodiorites indicating the primary controls on mineralisation. As well as providing an obvious follow-up target, this mineralised zone presents as an excellent pathfinder to rollout exploration over the entire 25,600 Ha tenement package.

Executive Director, Mike Parker, commented:

"First pass reconnaissance work at our Canyon Project has commenced and we are pleased to have found widespread evidence of copper oxides so early on. The geology is intriguing, and we are quickly developing our understanding of some controls on the copper oxide distribution.

"Our follow-up work at Canyon will include remote sensing, mapping, and rock geochemistry aimed at defining the most prospective zones within our large 25,600 Ha application area. It's an exciting time for Solis as we move forward with our vectoring and targeting strategy".

An initial reconnaissance visit to the Canyon Project (Figure 2) has confirmed the presence of copper oxides in intrusive rocks in a zone adjacent to a major cross-fault (Figure 3). The copper oxides were observed sporadically in road-cuts over a zone of approximately 400m in length, trending in a NNW direction, and are predominantly present as fracture and joint fills in largely unaltered porphyritic quartz granodiorites (Figure 1).

This area is 4.5km SE of previous exploration drilling that was permitted in 2013 (Figure 3). No results of this drilling have been located for confirmation. Continuing along this NNW trend beyond the tenement boundaries are the known copper oxide occurrences of Los Pinos (14.5km) and Nispero (21.0km) (Figure 2 and Figure 3).

The extent of the mineralised zone encountered is undefined and the oxides occur in distinct discontinuous patches from 0.5 to 3m in size. No quantitative estimate of mineralisation is feasible due to the nature of the outcrops, the evident discontinuities, ubiquitous dust, and the early reconnaissance nature of the geological inspection. Follow-up in this area will include detailed mapping, undertaken to add to geological understanding of the copper oxide occurrences and aiding the rollout of additional exploration strategies across the entire tenement package.

The assays obtained from two rock samples are shown in Table 1.

Note: The mineralisation identified, and its associated alteration, is considered a "pathfinder" exploration indicator for the potential presence of associated porphyry copper mineralisation in the tenements. Such mineralisation and alteration do not guarantee the presence of associated porphyry mineralisation and thus the significance of the assays and images are strictly in the context of exploration potential. The nature of grab samples implies that they are not necessarily representative of broader mineralisation, nor is the presence of such broader mineralisation implied.

The host rocks are characterised by large (up to 5mm) euhedral hexagonal primary biotite crystals and partially weathered pyrites. Whilst the copper mineralisation is predominantly a secondary weathering product, inspection of the area shows some potassic alteration related to veining, and the presence of <5mm wide sugary-textured quartz veins with weathered Cu oxides (Figure 4) which may indicate a primary source of the mineralisation. On a larger scale, distinct zones of late cross-cutting porphyritic diorite dykes up to 30m wide appear to have a spatial, roughly parallel, relationship with the presence of Cu oxides observed in the joints and fracture zones (Figure 5).

This area was sampled and returned assays of 0.53% Cu and 0.023% Mo. Sample number 22122, coordinates 383514E and 8546240N - WGS84 18S. <5mm wide sugary-textured quartz veins (parallel to open joint in photo) appear to have a primary control on mineralisation in this area.

Late porphyry dioritic dykes identified (partially indicated in yellow) with evidence of cutting the granodiorites and dipping steeply east. These barren dykes, some up to 30m wide, appear to exert a geological control on some of the mineralisation.

Next steps

Following the positive reconnaissance at Canyon, Solis will initiate work programs including remote sensing, mapping, and rock geochemistry to vector in on the most prospective areas.

The corridor that appears to be most favourable due to previous exploration and the presence of known occurrences has a strike length of 25km in the application area. In addition, potential for the existence of parallel corridors adds considerable exploration prospectivity and will be subject to further evaluation.

Canyon Project

Solis has made applications for 27 exploration concessions, totalling 25,600Ha, in a contiguous block known as the Canyon Project. The target is copper porphyry mineralisation, principally oxides, situated on a NW-SE prospective trend with known porphyry occurrences just outside the application area, as well as reported exploration activities within the area itself.

The application area contains a belt of intrusive rocks identified as the Coastal Intrusive Belt containing various Coastal Batholiths that stretch from the Ecuadorian border in the north to the Chilean border in the south along the coast of Peru (Figure 6).

These rocks, of Late Jurassic to Cretaceous age, host (from south to north) Solis' Ilo projects (Ilo Este, Chocolate, Chancho Al Palo) as well as important copper deposits of Tia Maria and Zafranal in Arequipa, the Almacen prospect 8km south-east of the applications, and the Los Pinos project 4km north-west, plus several other Cu projects and prospects (Figure 6). Additionally, the Canyon applications are bound to the east by the operating Cerro Lindo VMS mine.

The application area is approximately 22km by 12km and the geology predominantly consists of granodiorite and tonalite. These intrusive rocks dip steeply to the west with structures aligned along NW-SE strike. Prominent high-angle faults cut across strike and seem to localise the occurrences of porphyry style mineralisation within the intrusive rocks.
