• Commenced substantial first phase of RC drilling at 100%-owned Nanadie Copper-Gold Project
• Expanded Bluetooth Gold Prospect drilling program to further define near-surface oxide gold mineralization
• Received anomalous gold results from aircore drilling at Edjudina Range Gold Prospect

Solstice Minerals' December 2025 quarter was highlighted by the start of a substantial first phase of Reverse Circulation (RC) drilling at the Company's 100%-owned Nanadie Copper-Gold Project, where it sees excellent potential to materially add scale to an already significant West Australian copper-gold deposit. The Phase 1 RC program, now expanded to 6,300m, is designed to extend the current 150m wide and 900m long disseminated sulphide system and increase drilling density in priority areas within and below the current 40.4Mt Mineral Resource Estimate (MRE) containing 162,000t of copper and 130,000oz of gold. Geological observations from the initial 13 RC holes have provided strong impetus for continued drilling. At the Yarri Project, Solstice prepared a 2,000m RC drill program to further define the thick, shallowly dipping panels of near-surface oxide gold mineralization discovered at the Bluetooth Gold Prospect, while also testing down-plunge positions in the underlying fresh rock profile. Significant gold intercepts from 2025 drilling at Bluetooth include 18m @ 3.06g/t Au, 29m @ 1.58g/t Au, and 20m @ 1.98g/t Au. The Company also received anomalous gold results of up to 10m @ 0.47g/t Au to end-of-hole from aircore drilling at the Edjudina Range Gold Prospect, confirming and further defining zones of gold anomalism in the weathering and transported profile. Solstice ended 2025 with $13.4M in cash and no debt, providing excellent flexibility to advance its drilling programs and pursue value-accretive opportunities.

Solstice remains focused on adding commercial value to its portfolio of high-quality copper and gold assets in the West Australian Goldfields through disciplined, drill-based exploration. The Company looks forward to reporting assay results from the Nanadie Copper-Gold Project drilling as soon as they are available, and plans to continue advancing its pipeline of gold exploration targets at the Yarri and Ringlock projects.
