Solis Minerals Lists on ASX and Updates on Mostazal Drilling in Chile

Vancouver, BC - December 24th 2021 - Solis Minerals Limited (ASX: SLM, TSXV: SLMN, FSE: 08W) (“Solis Minerals” or “the Company”) is pleased to announce its successful listing on the Australian Securities Exchange (ASX) following its very well-supported IPO.

The Company raised a total of A$5.5 million through the issue of 27,500,000 Chess Depository Interests (“CDIs”) at A$0.20, with one attaching option for every two shares subscribed in the IPO with an exercise price of AUD$0.30 for a period of two-years from the date of issue.

Upon closing, the Company has in excess of A$7.0 million cash at bank, and is very well placed to commence its highly anticipated maiden drilling program at the Mostazal Copper Project in Chile, one of the largest copper production nations in the world.

CEO Jason Cubitt commented: “We were pleased to see the support of past shareholders and we welcome many new shareholders to the company in the IPO. I’d like to thank the administrative and legal teams in both Canada and Australia for supporting this achievement and, in particular, thanks go to our lead manager in Australia, Euroz Hartleys, for managing distribution of the IPO. We now look forward to a busy field season commencing January 2022 and the potential for a significant new copper discovery.”

Net proceeds from the IPO will be primarily allocated to funding the upcoming drill program at the Company’s 100%-optioned Mostazal Copper Project in Chile’s Atacama Desert where previous exploration has outlined significant near surface copper mineralisation.

Mostazal Copper Project Summary

The Mostazal property is located 80 kilometres (km) northeast of Copiapo, Chile (Figure 1) and within the Domeyko fault — a major structural control for some of the world's largest and most productive copper mines*, including Chuquicamata and Escondida, and 40 km south of Codelco's El Salvador mine (Appendix 1).

The first program of drilling will total approximately 2,900 metres diamond drilling in two phases, is expected to commence in mid-January continuing through until mid-March, and will initially target both porphyry and manto-style copper mineralisation.

As well as testing the copper at near surface, the Company intends to undertake the first-ever drill testing of an interpreted porphyry feeder system underlying a 4 km by 2.5 km, north-south-trending, belt of outcropping copper mineralisation, small-scale mine workings, and geochemical and geophysical anomalies. Four main target areas have been identified (Figure 2) on the basis of historical drilling, geochemical and geophysical surveys, and structural interpretation and modelling.

The Mostazal West target (Target Area 1) is located immediately west of stacked copper-bearing manto lenses and is characterised by the presence of a magnetic low and chargeability high geophysical anomalies. The Company is targetting a potential source of copper mineralisation beginning at a depth of 300 metres – about 100 metres deeper than prior drilling and immediately adjacent to the area of recent exploitation.

The Central target (Target Area 2) is located immediately beneath known manto copper lenses where historical, relatively shallow drilling (Figure 1) to a depth of approximately 150 metres, has encountered wide zones of high-grade copper mineralisation (Table 1). The Company is targetting to penetrate though stacked copper-bearing manto lenses to test for an interpreted buried porphyry/ feeder structure beginning at a depth of approximately 300 metres.
