Xstreco is carrying out an internal pre-economic assessment of large scale production at each of our five mineral assets, together with the concentration and refining capacity that would process the material. It is a running process, it remains ongoing, and no figures are published.

Xstreco completed the economic and engineering planning for production at the Rumichaca and Tincopalca properties in March 2026. The operating permits required to move into production are in place at both, and the next step is small scale pilot production, beginning at Rumichaca.

Xstreco completed the engineering definition, the plant layout and the cost planning for small scale pilot production at the Rumichaca property in March 2026. The property holds the operating permits required to move into production.

Xstreco completed the engineering definition, the plant configuration and the cost planning for small scale pilot production at the Tincopalca property in March 2026. The property holds the operating permits required to move into production.

Xstreco issued its Group policy framework, comprising the Code of Conduct and the supporting Group policies, on 14 June 2025.

A test pit programme was completed at the Rumichaca property across the sectors identified by earlier field work, and reported in May 2025. The programme identified the principal gold-bearing horizon.

Xstreco completed an internal base case economic evaluation across all five mineral assets on 20 May 2025, testing the case for taking each of them forward to operation and production. No figures are published.

A geological and geochemical field programme was completed at the Rumichaca property, sampling the river terraces and the active fluvial deposits, and reported in November 2024.

A ground induced polarisation, resistivity and magnetometry survey was completed at the Tincopalca property between September and October 2024, and proposed positions for future drill testing.

A reconnaissance rock sampling programme was completed across the Tincopalca property and reported by a commercial testing laboratory in July 2024.

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 summary of the Churubamba property, covering mapping and reconnaissance geochemical sampling over the altered zone and its margins, was reported in December 2022.

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.

A field evaluation of the Cochabamba property, covering traverse mapping, structural measurement and rock chip and channel sampling on the main structure, was reported in November 2018.

A reconnaissance visit in 2007 by an external exploration company, working on adjoining ground, mapped the local geology at what is now the Cochabamba property. The report forms part of the technical record held on file.

An evaluation of the Tincopalca property completed in 2007 mapped the local geology and altered zones along a faulted contact, and took a reconnaissance sample suite.
