Radius Advances Permitting and Defines an Expanded Copper Mineralization Footprint at Tierra Roja Project, Peru

The most recent news (March 18, 2026) indicates that Radius Gold is in the final administrative stages of permitting for its Tierra Roja copper project in Arequipa, Peru. The company has received provisional surface land authorization from the SBN and has submitted the final application to the GREM to initiate exploration. Concurrently, surface sampling has expanded the known copper-silver mineralization footprint to a corridor of 750m by 450m, much of which is covered by caliche, suggesting potential for mineralization to continue at depth. This follows the February 2026 announcement of an option to acquire 100% of the Jonco Silver Project, a bulk-tonnage polymetallic target with historical drill intercepts such as 254.5m @ 27.0 g/t Ag.

The impact is categorized as Routine - Positive. While the expansion of the geochemical footprint at Tierra Roja is technically encouraging, the news is primarily an incremental update on a long-delayed permitting process. - Permitting Delays: In October 2025, management expected final authorization by "early November 2025." As of March 2026, they are still in the "final administrative step." This persistent delay pushes back the primary catalyst (drilling) by several quarters. - Asset Diversification: The acquisition of Jonco adds a significant secondary project with historical data, reducing the binary risk of Tierra Roja. However, it also adds US$4.15M in cash payment obligations over five years, which is substantial relative to the company's current cash position. - Geochemical Expansion: Confirming mineralization beneath cover at Tierra Roja increases the scale of the target but does not replace the need for drill verification.

Radius Gold is a project generator and explorer focused on Latin America. - Flagship Project: Tierra Roja (Peru). A copper-gold-silver target showing characteristics of both Porphyry and IOCG systems. It has never been drill-tested. - Secondary Projects: Jonco (Silver-Polymetallic, Peru), Amalia (Gold-Silver, Mexico - JV with Pan American Silver), and Holly (Gold-Silver, Guatemala - JV with Volcanic Gold). - Strategy: Advancing high-impact targets to the drill stage, often utilizing joint ventures to limit downside risk.
