SOLARIS RECEIVES FINAL US$50 MILLION TRANCHE UNDER ROYAL GOLD FUNDING PACKAGE

Solaris Resources Inc. has received the third and final $50-million (U.S.) tranche under its $200-million (U.S.) financing package with RGLD Gold AG, a wholly owned subsidiary of Royal Gold Inc.

Receipt of the final tranche completes the three scheduled instalments under the financing package, comprising an initial $100-million (U.S.) tranche and two subsequent $50-million (U.S.) tranches.

The company reported cash and cash equivalents of $54-million (U.S.) as at June 30, 2026. The additional $50-million (U.S.) further strengthens Solaris's balance sheet and provides additional financial flexibility to advance its social, permitting, technical and operational workstreams in parallel as it progresses Warintza toward a fully permitted project.

Matthew Rowlinson, president and chief executive officer of Solaris, commented: "Receipt of the final tranche completes the $200-million (U.S.) Royal Gold funding package and materially strengthens our liquidity as we advance Warintza's social, permitting and technical workstreams. The package has provided substantial capital without an equity issuance while preserving strategic flexibility. We thank Royal Gold for their partnership and continued support as we responsibly advance Warintza."

Royal Gold financing package

The $200-million (U.S.) non-dilutive financing package was entered into in May, 2025, and comprises a gold stream and net smelter return royalty. The financing was payable in three instalments: $100-million (U.S.) at closing, $50-million (U.S.) following publication of the prefeasibility study and receipt of the environmental impact assessment technical approval, and the final $50-million (U.S.) tranche following completion of the required security filings.
