Solis Completes Magnetometry Survey at Cinto
HIGHLIGHTS
- Magnetic anomaly recognised on batholith margin
- Coincident WorldView 3 remote sensing and magnetic anomalies
- Clear zones of interest identified for follow-up IP for drill targeting
- First-pass drill program anticipated for 2025
West Leederville, Western Australia–(Newsfile Corp. – October 15, 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 Cinto Project situated in the prospective Cenozoic Porphyry Belt of southern Peru (Figure 1 – geology).

Solis has completed a combined drone and ground magnetometry survey over its Cinto permits (Figure 2). The survey shows magnetic anomalies south of an intrusive batholith contact with corresponding alteration detected from WorldView 3 remote sensing work (Figure 3). Areas of low magnetic response north-east of the batholith contact represent alteration that contains the area of visible copper mineralisation present at Cinto.
Executive Director Mike Parker commented:
“Cinto has an incredible address on the regional Incapuquio fault system with the giant Toquepala porphyry copper mine only 15km to the north. The magnetometry survey provides excellent insight into the geology and alteration at Cinto.
“Combined with our previous remote sensing work, and mapping and sampling – including our high grade copper sample area in the northeast of the permits – we are forming an exceptional toolbox to extract the maximum benefit from our ongoing porphyry exploration. We will now conduct further assessment using IP surveys to guide our first-pass drill program2.”

Survey Details
Peruvian geophysical contractors Real Eagle Explorations completed 120km of drone lines from 21 to 30 August 2024. A GEM GSMP-25u mobile magnetometer was deployed supported by a Matrice 300RTK drone. The base station was a GEM GSM-19Wv7.0 Overhauser. 200m spaced lines, with appropriately spaced tie-lines, were flown at a maximum velocity of 28km/h with an altitude range of 30-80m above ground. From 11 to 18 of September 2024, 41km of ground magnetometry data acquisition lines were carried out in the north of the permits to complete the survey at 161km of survey lines in total. The change of method was due to unsuitable conditions for drone flying. The geophysical contractors carried out thorough comparative testing on the methods and levelled the data to form one complete magnetometry dataset.
Interpretation and Observations

For purposes of interpretation, Solis has overlain preliminary Total Field data obtained in the magnetometry surveys with WorldView 3 remote sensing data. Geological features are also referenced. High magnetic response areas are viewed as potentially related to the presence of magnetite – a vector for alteration associated with porphyry copper mineralisation. Low magnetic response areas are viewed as magnetite destruction areas – a common sign of hydrothermal alteration.
Figure 3 shows a central late Cretaceous batholithic intrusive, (interpreted to be a structural outlier of the Cretaceous batholith related to the Toquepala porphyry deposit), which has a zone of high magnetic response of dimensions 4km x 1km striking WNW-ESE along its southern flank. On the southern flank of the magnetic anomaly itself, several zones of alteration were detected by WorldView 3 remote sensing in a broad swathe 6km long and 1km wide. Alteration signatures include propylitic, phyllic, argillic, and jarositic mineralisation predominantly in fine-grained tuffs. A low magnetic response area with associated WorldView 3 argillic alteration zones indicates a zone of more intense hydrothermal alteration.
Additionally, a SW-NE orientated magnetic anomaly zone was identified partly covered by Cenozoic forearc basin sediments of the Moquegua Group (M1-M3 on Figure 2). This zone has a partial remote sensing response only due to the recent cover rocks and resembles a high angle fault intersection with the Incapuquio fault zone. Cross-faulting zones are considered to be potentially more prospective in Andean porphyry belts1.
The north-east flank of the batholith has a zone of propylitic alteration defined by Worldview 3, which encompasses the high grade copper sample area previously reported2. To the east of this, the low magnetic response area coincident with an associated jarosite alteration halo indicates a zone of more intense hydrothermal alteration.

Conclusions and Next Steps
The high magnetic anomaly south of the batholith is flanked by alteration to the south which represents a high priority target for immediate follow-up mapping and geochemistry. To the north-east of the batholith, the known high Cu grade area potentially extends into an area of alteration to the east. Evaluation of areas for follow-up IP programs will be carried out to accelerate permitting for drilling these first-class targets during 2025.
Exploration and Drilling Pipeline
Solis is advancing its portfolio of targets in the Coastal Belt of Peru to targeted drilling programs as shown in the table below. The data in red indicates progress since the last announcement on 3 October 20243.
