Operations Update: Bonanza Mine

 

Bonanza vein study progressing well

 

Nativo Resources plc (LON:NTVO), a gold-focused mining company with interests
in Peru, is pleased to provide an update on ongoing field activities at the
Bonanza Gold Mine on the fully owned Tesoro Gold Concession.

 

Surface Exploration - Trenches, Mapping and Sample Analysis

·    The surface trenching programme along the Bonanza Vein has now been
completed

·    20 trenches were excavated at 25-metre intervals to depths of 1.2-1.5
metres to expose the vein structures beneath the colluvial cover

·    Each trench was cleaned, geologically logged, structurally measured
and photographed, providing the foundation for detailed surface geological
mapping

·    Systematic channel sampling was completed within the surface
trenches, with samples taken at 1-metre intervals across the exposed
mineralised structures to characterise grade variability along strike - these
samples will support the preparation of geological sections and longitudinal
profiles and will be incorporated into the ongoing data-processing and
interpretation work

·    Collected samples are being logged and prepared for despatch to the
Certimin laboratory in Lima - packaging and sealing was completed on 16
November 2025, and the first batch will be dispatched this week

·    Results will feed directly into the sample analysis and data
processing workstream, enabling the refinement of longitudinal sections and
mineralised shoot interpretation

·    Preparation of geological sections and longitudinal profiles has
commenced - the field mapping data, combined with structural measurements and
preliminary trench assay results, are currently being digitised

·    This modelling work is essential for defining priority underground
targets and supports the underground works and mine planning components of the
overall study

 

Construction and Rehabilitation of Mine Access

·    Work on mine access rehabilitation is advancing in line with the
preliminary engineering plan to prepare the site for full underground re-entry

·    A complete topographic survey of the Bonanza shaft collar, access
path and first underground platform has been finished

·    The engineering team has started preparing the detailed design for
the shaft access system, including ladders, platforms, ventilation pipes, and
water evacuation lines

·    All supports required for the first rehabilitation stage have already
been procured and are on site

 

 Camp Establishment and Operation

·    Significant progress has been made in the planning for upgrading the
central operations camp that will support both the Bonanza and Morrocota mines
and provide full operational continuity

·    Capacity is being increased from 20 to 40 personnel, including
operational, geological, security and service teams

·    Work scheduled for completion over the next two weeks includes:

•     Completion of accommodation facilities for all personnel

•     Restoration of water distribution lines for domestic use and
sanitary facilities

•     Commissioning of a new generator and verification of the
electrical load distribution centre

•     Installation of a Starlink internet system to ensure stable
communications between the camp, mine and Lima office

•     Preparation of storage and workshop areas, including segregation
of fuel, reagents, consumables and mechanical equipment

•     Establishment of HSE safety zones and mandatory access-control
points

 

Mining Contractors

·    Prospective mining contractor site visits have commenced following
the request for tenders issued last month to qualifying contractors in
preparation for the results of the Bonanza Vein Study

·    Site visits enable firms to inspect conditions, assess logistical
constraints, and confirm equipment and workforce requirements ahead of
submitting formal proposals

·    Once all proposals have been received, Nativo's technical and HSE
teams will carry out a rapid but structured evaluation, followed by a
selection process

 

Field activities, including underground works, will advance in parallel over
the next two weeks to complete the Bonanza Vein Study. Nativo's objective is
to resume small scale mining operations, initially at Bonanza, by year-end.

 

Technical Preparation for Adding Capacity Through New Mines

In parallel, with the above field activities, the Company has completed a
concession wide study across the 300-hectare Tesoro Gold Concession to
identify additional areas for gold mining. The study included mapping and
sampling, and has used the available historical geophysical, geological and
mine data from 2007 to 2014, to identify new veins for development. Fresh
mapping has verified the existence of multiple veins previously identified as
"Zona Central" and "Zona Este", which extend across the Company's concession
and are considered of high potential with surface grades on mapped veins of up
to 10 g/t gold(*). Five new sites have been identified with potential as ore
shoots that may be suitable for small scale mining.

Stephen Birrell, Chief Executive Office of Nativo, commented:

 

"Preparations to re-open the Bonanza mine are advancing at pace. We look
forward to providing further updates upon completion of the Bonanza Vein Study
and are targeting a resumption of mining operations before year-end. In
parallel with this we have identified five new ore shoots which merit detailed
study for their potential to add further mining capacity on the concession."
