Overview
One of five mineral assets in Xstreco's Peruvian portfolio, reactivated under our staged development programme. Antioquia sits at an average 1,600 metres above sea level in hillside terrain east of Lima, reached by the Carretera Central through Chaclacayo. Surface and underground exploration work has been carried out, including an exploration adit driven in 2023 toward a projected vein. The vein is interpreted to continue beyond the current face, and the adit is retained as direct underground access for the next phase of work. Relations with the communities around the property are good, and the formal engagement programme is scheduled as part of the next phase of work.
Location
Cieneguilla, Chaclacayo and Antioquia districts, Lima and Huarochiri provinces, Lima department
By-products
Precious metals
Access
Approximately 60 km and around 2 hours from Lima via the Carretera Central and the California turnoff, with a final section on an unmade track
Permits and approvals
The property is at the environmental permit application stage for the next phase of work. Development and production activity follow the grant of the relevant instrument.
How activities are assessedWork programme
The geological setting of the property and the exploration programmes completed on it.
Geological setting
Antioquia sits in the pre-Andean foothills of central Peru, on the tonalite, granodiorite and diorite of the Coastal Batholith. Quartz veins with associated alteration cross the centre of the property, and a second fault set follows the regional Andean grain. Much of the ground is masked by sand and colluvium weathered from the batholith itself.
Work completed
Three programmes have been completed. Geological mapping and surface sampling in 2022 covered mapped vein and fault structures across the central sector. An exploration adit was driven in 2023 toward a projected vein, and the target is interpreted to continue beyond the current face. The adit is stable and accessible, and it gives direct underground access for survey, underground mapping, sampling and short drilling toward the projected position. A ground induced polarisation, resistivity and magnetic survey followed in 2024 over the central sector, and identified chargeability anomalies.
Xstreco is privately held and is under no obligation to publish mineral resource or mineral reserve information. No resource, reserve or production figure is published on this page. Detailed technical information is available to qualified parties on request.
Working responsibly
A single framework of our Group requirements applies to every activity on this property.
How we work with communities
Our assets sit in settings where farming, pasture and settlement long precede mining. Engagement is with people already living on the ground.
Engagement continues for the life of the activity and through its closure.
Our approach to communitiesNews and notices
Updates relating to this asset, most recent first.
A ground induced polarisation, resistivity and magnetometry survey was completed over the central sector of the Antioquia property in March 2024.
An exploration adit was driven at the Antioquia property in 2023 and is retained as underground access for further work. The projected vein position is interpreted to lie beyond the current face and is a target for the next phase.
A geological and mining reconnaissance of the Antioquia property, covering surface mapping and rock chip and channel sampling across the central sector, was reported in November 2022.
A first suite of reconnaissance rock samples from the Antioquia property was analysed by an accredited commercial testing laboratory in Lima and reported in May 2021.
