Radius Gold Reports Multi-Element Geochemical Results Supporting Porphyry Interpretation at the Tierra Roja Core Target, Peru

Radius Gold Inc. (RDU) released multi-element geochemical results from rock and soil sampling at its Tierra Roja copper project in southern Peru. Rock sampling confirms strong correlations between copper, silver, gold, potassium, and molybdenum, consistent with the upper, oxidized levels of a porphyry copper system. Soil sampling shows classic porphyry signatures, including inverse copper-zinc relationships and depleted lead/zinc over the high-copper core. Potassium enrichment (>2% K) in both rock and soil aligns with potassic alteration of the surrounding Jurassic volcanic sequence.

Permitting remains the primary near-term hurdle: the company holds provisional SBN authorization for surface access and has submitted an application to GREM for exploration authorization. Drilling is pending GREM approval. Next steps include a larger property-wide geochemical survey to map metal zonation and vectors, with results reported as they become available.

Radius Gold Inc. (RDU) released a routine positive exploration update confirming the geological model established during its July 2026 site visit and March 2026 footprint expansion. The company remains in the pre-drill exploration phase, with the release not introducing new financial results, resource estimates, or drilling results.

An August 2026 private placement raised $1.24 million, providing sufficient working capital to continue surface exploration and permit processing. Future capital will be required to fund the actual drill program and Jonco option earn-in payments. The news aligns with management's stated focus on securing GREM authorization to commence drilling, showing no material deviation from prior expectations.

Radius Gold Inc. is an exploration-stage company with a portfolio of precious and base metal projects across Peru, Mexico, and Guatemala. Its flagship asset is the Tierra Roja Copper Project in Southern Peru, a 100% owned porphyry copper target on state-owned land. Recent surface work has expanded the known geochemical footprint to approximately 750m strike by 450m width, revealing widespread copper oxides, porphyry dikes, and potassic alteration.

The company also holds interests in other assets, including the Jonco Silver Project in central Peru, which spans 3,830 hectares with an option to earn 100%, the Amalia Gold-Silver Project with a 35% interest in a joint venture with Pan American Silver, and the Holly Gold-Silver Project with a 40% interest in a joint venture with Volcanic Gold Mines. Management is led by CEO Simon Ridgway and President Dr. Luke Longridge, a former Teck Resources structural geologist, with a focus on advancing Peruvian projects and unlocking value from joint venture assets.
