Solaris Resources Confirms Significant Copper Deposit at Patrimonio Target

Solaris Resources (TSX:SLS) Confirms Significant Copper Deposit with 96m of 0.59% CuEq From Near Surface within 144m of 0.50% CuEq and 148m of 0.52% CuEq in First Two Reconnaissance Holes at Patrimonio Target

Solaris Resources (TSX:SLS) reports assay results from the first two exploration drill holes at the Patrimonio target at the Warintza project in southeastern Ecuador. These results support the discovery of a significant new copper deposit south-west of central Valinza.

Patrimonio was discovered in June 2023 as part of a mapping and sampling program near Warintza Central, more specifically, approximately 0.5 km southwest of Warintza Central. These early drill holes have now confirmed the existence of this extraordinary copper reserve. Additionally, unique skarn mineralization has been observed in carbonate-rich volcanic sequences. The origin of this mineralization remains under investigation.

Drilling details indicate that the SLSP-01 hole drilled to the northwest exposed 50 m of 0.75% CuEq1 and 96 m of 0.59% CuEq1 from surface, with a larger span of 144 m of 0.50% CuEq1. This occurs prior to entry into the lightly mineralized dacitic porphyry reservoir. On the other hand, hole SLSP-02, drilled west from the same platform, intersected 148 m of 0.52% CuEq1 in a more extensive 276 m of 0.40% CuEq1 near the surface, culminating in porphyry.

Copper Deposit at Patrimonio Target

Two distinct mineralization stages have been identified. The first is evident in the upper part of the hole and shows intense epidote-magnetite alteration (skarn) and secondary biotite alteration (potassium) in a series of volcanic structures. Subsequent phases are associated with the later development of dacite porphyry and were affected by quartz-sericite-pyrite alteration that weakened the mineralization of the volcanic section mentioned above.

The discovery of drill core indicates that the epidote-magnetite (skarn) mineralization has a different origin than the dacite porphyry, suggesting the interesting possibility of further skarn mineralization and even its discovery in the legacy Sources of intrusion in anomalies.

In addition, later quartz-sericite-pyrite alteration influenced by dasnic porphyry contains approximately 10% sulfides, mainly pyrite, exceeding chalcopyrite. This suggests the potential for similar targets in other porphyries within the Warintza Cluster, where favorable sulfide horizons associated with previous stages of alteration are dominated by chalcopyrite rather than pyrite.

Current efforts are in place for meticulous mapping and sampling to understand this mineral system better and to determine directions for skarn and alteration layers. This will also assist in setting priorities for drill locations that are presently in the construction phase. The copper mineralization is still not fully explored towards the northwest, south, and west, while it touches a slightly mineralized quartz-monzodiorite porphyry on its northeast side.

Patrimonio is characterized by a north-south molybdenum soil anomaly that measures approximately 1.5km x 0.5km, surrounded by a copper soil anomaly extending towards the west. Here, outcropping porphyry shows noticeable alteration and veining, situated on the western flank of an assumed major north-south fault close to Warintza Central.

Highlights from the results are as follows:
