Solis Announces Acquisition of Highly Prospective Cucho Copper Project, Peru

HIGHLIGHTS

Agreement to acquire up to 75% of the Cucho Copper Project ("Cucho" or the "Project"), Peru, via staged earn-in with an option to acquire 100% (subject to shareholder approval).

Project is a large-scale, partially outcropping copper-molybdenum-silver porphyry system, with excellent infrastructure access only 44 kilometres from the Pacific coast.

Cucho is complementary to Solis Minerals' existing Peruvian portfolio, providing an asset with historical drilling and very attractive untested drill targets.

Historical exploration includes 2,000 metres of diamond drilling and confirms significant copper mineralisation from surface, with both oxide and primary sulphide copper.

Previous drilling encountered significant mineralisation in all drill-holes1 with grades consistent with operating mines across the Andean copper belt:

COP14-01: 169.7 metres @ 0.24% Cu, 0.012% Mo and 1.0 g/t Ag (from surface)

Inc. 39.5 metres @ 0.34% Cu, 0.014% Mo and 1.1 g/t Ag (from 27.3 metres)

COP14-02: 178.7 metres @ 0.23% Cu, 0.022% Mo and 0.9 g/t Ag (from 38.6 metres)

Inc. 20.0 metres @ 0.32% Cu, 0.020% Mo and 0.8 g/t Ag (from 135.9 metres)

COP14-05: 96.7 metres @ 0.28% Cu, 0.018% Mo and 1.4 g/t Ag (from 37.2 metres)

Inc. 52.7 metres @ 0.35% Cu, 0.016% Mo and 1.0 g/t Ag from 82.5 metres

COP14-06: 175.4 metres @ 0.28% Cu, 0.012% Mo and 1.3 g/t Ag (from surface)

Inc. 91.2 metres @ 0.33% Cu, 0.007% Mo and 0.8 g/t Ag (from surface)

COP14-07: 269.1 metres @ 0.25% Cu, 0.011% Mo and 1.1 g/t Ag (from surface)

Inc. 19.9 metres @ 0.36% Cu, 0.002% Mo and 1.0 g/t Ag (from 13.6 metres)

Inc. 18.0 metres @ 0.36% Cu, 0.020% Mo and 0.6 g/t Ag (from 138.2 metres)

Historical drilling had limitations that led to a 2014 Technical Report, prepared under NI-43- 101 Standards, concluding that "the main geochemical and geophysical anomalies were left without verification by drilling". Solis Minerals plans to drill these in early 2026.

Cucho is located 40 kilometres from Element 29 Resources' Elida project (Inferred Resource: 321Mt @ 0.32% Cu. 0.03% Mo, 2.61 gt/t Ag)2. Market capitalisation of CAD$157M3.

Project to be acquired through a staged, low-upfront cash structure with no minimum spend.
