Radius Gold updates Jonco and Tierra Roja properties
July 21, 2026 – TheNewswire - V ancouver, British Columbia – Radius Gold Inc. (TSX-V: RDU) (“Radius” or the “Company”) is pleased to report on site visits by Radius President Dr. Luke Longridge to the Jonco and Tierra Roja Projects, Peru.   Jonco Site Visit In anticipation of the execution of the formal Option Agreement for 100% of the Jonco Silver Project (announced 15 July 2026), Dr. Longridge visited the Jonco site on the 3 rd and 4 th of July, and was accompanied by Radius Chairman and CEO Simon Ridgway, several members of Radius’ Peruvian team, and Frederick Felder, representative of Minera Joncijirca S.A.C. Mr. Felder is an experienced geologist and former EVP of Greystar Resources and was instrumental in the advancement and resource expansion of the world-class Angostura Au-Ag deposit in Colombia. Mr. Felder has been involved in the Jonco project since it was originally staked in 1996 and has accumulated a wealth of knowledge on the geology of the property.
The site visit, together with a legacy dataset that includes geophysics, geochemistry, petrographic and fluid inclusion studies, and the database for 11 historic holes, has allowed for the transfer of this valuable geological knowledge. The Jonco Silver Project hosts a bulk-tonnage polymetallic Ag-Au-Pb-Zn epithermal system associated with dacite flow domes and hydrothermal breccias, and diatreme structures within the Miocene Volcanic Belt of northern Peru. Mr. Felder believes that Jonco represents a telescoped polymetallic epithermal system that has been tectonically juxtaposed by several episodes of deformation.
Further understanding and delineating of the disseminated polymetallic epithermal mineralization will be the initial focus for the Radius team, while also evaluating the multiple additional targets already identified by Mr. Felder, and based on historical work. Radius is currently reviewing all historical data and will be conducting re-sampling of historic drill core and trenches. During the site visit, the Radius team visited historic trenches and drill collars, and discussed the planned work programme for the Jonco Project, which will be announced in due course.
Furthermore, Radius’ senior leadership met with community representatives at the nearby Cajamarquilla community, who hold surface rights over much of the area covered by the Jonco claims. Radius is working towards obtaining agreements with the Cajamarquilla community, which are required for permitting of drilling and other exploration activities.   Figure 1 : Photographs from the Jonco Project.

We look forward to continuing to work with them to secure the necessary surface access agreements and permitting for future exploration activities at Jonco.
I am even more excited about the project now that I have seen it in person. Strong alteration associated with polymetallic mineralization, together with favourable topographic relief, confirms the potential for a bulk-tonnage target”.   Tierra Roja Site Visit Dr. Luke Longridge visited the Tierra Roja property on the 7 th of July 2026, accompanied by Alejandro Ly (VP Exploration) and Felix Cerron, an experienced geologist who conducted detailed geological mapping and assessment of the property prior to acquisition by Radius. Several observations were noted by Dr. Longridge during the visit and are presented in the figures below.
These include: Widespread Cu-oxide minerals beneath 1-3m thick cover of caliche. Cu-oxides are most visible in quebradas (ravines/valleys) but excavations beneath the caliche away from these valleys reveal widespread Cu-oxide minerals.   The presence of porphyry dikes containing disseminated copper oxides.   Extensive silicification and sericitic and potassic alteration of the Jurassic andesite volcanics. These andesites represent the older host (country) rocks into which the mineralizing system has been emplaced.   Widespread disseminated Cu-oxide mineralization within the host andesite volcanics.   Presence of copper oxides at distances of over 1 km to the east from the 600 m x 800 m “Core Zone”.
Re-examination of assay data from rock chip samples collected prior to the acquisition of the project highlight this widespread copper distribution across an area greater than 4 km   Radius continues to engage with Peruvian government entities regarding drilling authorization at Tierra Roja. A surface work programme is being prepared for the Tierra Roja property, which will allow for more detailed characterization of the mineralizing system and its extents.

I look forward to working on both projects to realize their potential.” Qualified Person Luke Longridge, PhD, P.Geo, is the President of Radius and is Radius’s Qualified Person as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects.  Dr.
