Solis Completes Magnetometry Survey at Cinto

In This Article:

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.
