West Leederville, Western Australia–(Newsfile Corp. – February 5, 2026) – Solis Minerals Ltd (ASX: SLM) (“Solis Minerals”, “SLM” or “the Company”) is pleased to provide an update on the Cucho Copper Project (“Cucho” or the “Project”) (SLM up to 100%) in Peru.

Chief Executive Officer, Mitch Thomas, commented:

“Cucho is a standout project within our Peruvian portfolio. The broad mineralised copper intercepts, strong geophysical signatures, and clear structural controls highlight a system with genuine scale. Permitting is advancing rapidly. Against a backdrop of record copper prices and strong market fundamentals, our first drilling at Cucho aims to demonstrate the potential of this porphyry system and advance Solis Minerals toward resource discovery in 2026.”

Cucho Copper Project

Background

Cucho was discovered by geologists from Quippu Exploraciones (“Quippu” or the “Vendors”) (a Peruvian privately held exploration company) in 2008 in the Ancash Department of coastal Peru. Following a maiden drilling campaign in 2014, it was defined as a potential large-scale porphyry copper-molybdenum system. The project area was expanded by Quippu between 2021 and 2022 through the acquisition of neighboring concessions. Subsequent surface activities and re-interpretation of geophysics defined an expansive 3 x 1.8-kilometer mineralisation footprint.

Cucho represents a compelling exploration and development opportunity with extensive historical datasets, existing drill-defined copper mineralisation from surface, and clear geological indicators of a district-scale mineralised system.

The Company considers Cucho to have the potential to host a globally significant copper deposit and intends to advance the Project rapidly to exploration drilling.

Pursuant to the binding agreement signed with Quippu in October 2025, and now modified favourably by negotiated commercial terms, Solis Minerals has the right to earn up to a 75% interest in the issued share capital of a new joint venture company (“JVCo”) which will hold 100% of the Project via a staged earn-in, with an option to acquire a 100% interest³.

Due diligence

The Company has completed the following workstreams as part of its detailed due diligence:

• Permitting and concession review; drill permitting applications are advanced

• Logistics and infrastructure review; 40kms to the coast and excellent supporting infrastructure

• Geological modelling⁴; confirming several compelling targets

• Core relogging and lithology review; confirming geological modelling assumptions

• Drone magnetometry survey; results targeted for release Q1 2026; to support drill sequencing

• Surface mapping; including identification of new mineralised areas

• Application for adjacent concessions; expanding to the north and east of the project area⁵

Solis Minerals’ due diligence activities over recent months have reaffirmed a strongly favorable view of the exploration and project development prospectivity of Cucho.

Data collected during the due diligence phase has been reflected within the planned drill campaign scheduled for late Q2 2026. Approximately 14 drill pad locations are being permitted to provide flexibility during the drill campaign (Figure 2).

Commercial updates

Solis Minerals has renegotiated the terms of future milestone payments favorably to better align payments with key exploration milestones (permitting and drilling). Key differences from the terms announced 21 October 2025⁷:

1. Exercise phase

• Cash reduced from US$300,000 → US$100,000 payable February 2026.
• Share consideration of US$100,000 payable February 2026.
• Previously required payment of A$1,000,000 in SLM shares has been deferred and split into:
  • A$500,000 payable following Drill Permits phase (i.e., once permits are awarded);
  • A$500,000 payable following the Drilling phase (i.e., following drill completion).
• Solis Minerals’ equity at exercise adjusted to 10% (reflecting lower upfront consideration).

2. Drill Permits phase

• Cash increased from US$200,000 → US$300,000 upon receipt of drilling permits.
• Additional A$500,000 in SLM shares incorporated (deferred from Exercise phase).
• All payments are conditional upon full receipt of permits required for drilling.
• JVCo equity increases to 30%.

3. Drilling phase

• Share consideration increased by A$500,000 (the second half of the deferred Exercise phase).
• Cash component remains US$200,000.
• Importantly, both amounts are payable only upon completion of a 5,000-metre drilling program.
• JVCo equity increases to 51%, unchanged from the original terms. No other changes have been made to the Cucho transaction terms. Country and regional activity

The region surrounding Cucho is experiencing increasing exploration activity from major international mining companies, reflecting the district’s strong geological endowment and growing interest in large Andean porphyry copper systems.

Australian-listed AusQuest Limited (ASX: AQD) is actively drilling its Cangallo Copper Project, located within the same coastal Peruvian batholith that hosts Cucho. Cangallo displays comparable geological characteristics, including porphyry-style vein networks, multiphase intrusive centers, and a similar magmatic-hydrothermal evolution.

AusQuest has released results from 23 drill holes (21 RC and 2 diamond), demonstrating broad copper mineralisation⁸:

• CANRC001: 348m @ 0.26% Cu, 0.06 ppm Au from 6m

• CANRC002: 188m @ 0.28% Cu, 0.07 ppm Au from 214m

• CANRC003: 154m @ 0.37% Cu, 0.06 ppm Au from 36m

• CANRC004: 10m @ 0.17% Cu, 0.07 ppm Au from 228m

• CANRC005: 226m @ 0.22% Cu, 0.07 ppm Au from 4m

• CANRC006: 138m @ 0.17% Cu, 0.03 ppm Au from 270m

• CANRC007: 136m @ 0.25% Cu from 22m; 121m @ 0.26% Cu from 256m

• CANRC008: 304m @ 0.30% Cu, 0.06 ppm Au from 34m

• CANRC009: 130m @ 0.23% Cu from 18m; 242m @ 0.16% Cu from 166m

• CANRC010: 274m @ 0.19% Cu from 36m

• CANRC011: 124m @ 0.16% Cu from 18m; 126m @ 0.23% Cu from 226m

• CANRC012: 324m @ 0.30% Cu, 0.07 ppm Au from 36m

• CANRC013: 234m @ 0.30% Cu, 0.06 ppm Au from 110m

• CANRC014: 330m @ 0.30% Cu, 0.06 ppm Au from 32m

• CANRC016: 14m @ 0.14% Cu, 0.02 ppm Au from 278m

• CANRC017: 150m @ 0.21% Cu, 0.05 ppm Au from 276m

• CANRC018: 42m @ 0.20% Cu, 0.02 ppm Au from 14m

• CANRC019: 314m @ 0.20% Cu, 0.04 ppm Au from 106m

• CANRC021: 156m @ 0.16% Cu, 0.05 ppm Au from 2m

• CANDD001: 144m @ 0.15% Cu, 0.04 g/t Au from 686m

• CANDD002: 555m @ 0.26% Cu, 0.06 g/t Au from 5m

These intercepts are comparable to historical drilling at Cucho that confirm the presence of large, vertically extensive porphyry system⁹. Notably, historic drilling at Cucho averaged only 280m depth, with two holes ending in mineralisation and mineralisation remaining open in all directions, leaving significant untested potential.

The emerging Elida Copper Project, located 40 km from Cucho and owned by Element 29, demonstrates the region’s prospectivity. Elida hosts an inferred resource of 321.7 Mt @ 0.32% Cu, 0.029% Mo and 2.6 g/t Ag, and recently reported one of the most significant porphyry holes in Peru; 1,489m @ 0.44% Cu, 0.04% Mo and 4.1 g/t Ag (ELID037), with grades increasing at depth¹⁰. Elida is now regarded as one of the most attractive undeveloped copper porphyry projects in South America.

Both Cucho and Elida share hallmark features of Andean porphyry copper-molybdenum systems: large multiphase intrusive centres, extensive hydrothermal alteration, strong geophysical signatures, and long copper intercepts beginning near surface with clear expansion potential at depth.

Additional advanced exploration in the region includes Vale’s (NYSE: VALE) Umami Project, Alpayana’s Antarumi Project, and ongoing base-metals exploration by Fortescue (ASX: FMG) adjacent to the Cucho concessions (see Figure 3).

⁹ Comparisons with other projects or mines, including those that are in production or at a more advanced stage of development, are not intended to imply that the Company will achieve similar results, recoveries, or economic outcomes. The potential quantity and grade of any resource at Cucho is conceptual in nature, and there has been insufficient exploration to estimate a Mineral Resource. It is uncertain if further exploration will result in the estimation of a Mineral Resource. Investors should not place undue reliance on such comparisons.
