Masa Valverde Drilling Update
Results confirm and extend high-grade copper zones
which are expected to be the initial focus for mine development
Atalaya Mining (LSE: ATYM) is pleased to announce results from its ongoing
drilling programme at Proyecto Masa Valverde ("PMV"). At present, two rigs are
active and are focused on infill and extensional drilling at the Masa Valverde
deposit, where high-grade copper zones have been defined.
Highlights
· Notable high-grade copper zone drilling results include:
‒ MJ65: 25m at 2.93% Cu (from 568m)
‒ MJ72: 18m at 2.17% Cu (from 611m)
‒ MJ73W1: 83m at 1.19% Cu (from 579m), including 12m at 2.39% Cu
‒ MJ74: 53m at 1.36% Cu (from 599m), including 15m at 2.32% Cu
‒ MJ76: 46m at 2.11% Cu (from 575m)
‒ MJ76W1: 30m at 2.14% Cu (from 598m)
‒ MJ76W3: 25m at 2.54% Cu (from 604m)
‒ MJ79: 26m at 2.78% Cu (from 603m), including 10m at 4.39% Cu
· Results are primarily associated with stockwork-style
mineralisation, which is expected to be amenable for processing at the
existing Riotinto facilities
· Drilling supports Atalaya's initial focus on the Masa Valverde
copper zones, which are expected to be mined via the planned access ramp
· Ramp development is expected to begin once the purchase of
certain surface rights is completed and is subject to final Board approval
Alberto Lavandeira, CEO, commented:
"We are pleased to announce these exciting drilling results at Masa Valverde.
The high-grade copper zones that have been identified have the potential to be
mined selectively and deliver high-grade material to our Riotinto processing
plant.
Infill drilling will continue for the remainder of 2025, furthering our
understanding of the copper zones which are expected to form the basis for the
initial development of this satellite project, and of the separate zinc-rich
and gold-rich areas of mineralisation which could be exploited as part of a
larger-scale future development. Finalisation of the required land purchases
will allow Atalaya to begin ramp development.
Atalaya is in a fortunate position to develop regional deposits like Masa
Valverde in a capital efficient manner thanks to its significant existing
infrastructure at Proyecto Riotinto including its 15 Mtpa processing plant. We
also expect to benefit from the extensive underground mining capabilities
available in the region. Finally, we are thankful for the positive business
environment in Andalucía, as highlighted by the permitting timeline achieved
at Proyecto Masa Valverde."
Recent Drilling
Recent infill and extensional drilling at the Masa Valverde deposit is
confirming and expanding the areas of high-grade copper mineralisation. The
implementation of directional drilling has allowed Atalaya to efficiently
drill from surface at a spaced grid of approximately 50 by 25 metres over the
selected mineral-enriched zones, which are located at depths of over 500
metres. These high-grade zones are related to a late-stage tectonic event,
which involves the replacement of primary massive sulphide (pyrite) and
volcanic rhyodacite by copper (zinc-lead) veining-type mineralisation. This
mineralisation consists of coarse-grained recrystallised chalcopyrite with
minor sphalerite and galena, locally accompanied by silica and carbonate.
It is anticipated that this copper mineralisation will be amenable for
treatment at Atalaya's existing Riotinto processing facility, and therefore
this material is expected to be the initial focus for mining once the planned
access ramp has been developed.
Table 1 shows the most significant copper intercepts, consisting of
copper-rich stockwork (SW-Cu) and copper-rich massive sulphide (MS-Cu) ore
types. Additional intercepts are shown in the Appendix.

The locations of the drill holes are shown below in Figure 4. Priority has
been given to the high-grade areas where the drill hole spacing is tighter.
Further infill drilling is in progress in several areas.
Background
PMV is located in the Iberian Pyrite Belt of southern Spain approximately 28
km to the south of Atalaya's 15 Mtpa processing plant at Proyecto Riotinto.
PMV consists of a highly prospective land package that includes the Valverde
Exploitation Concession (CE Valverde), which contains the Masa Valverde and
Majadales volcanogenic massive sulphide ("VMS") type deposits.
Figure 1: Proyecto Masa Valverde Location
In April 2022, Atalaya announced a NI 43-101 compliant Mineral Resource
Estimate for the Masa Valverde and Majadales deposits. Thereafter, Atalaya
focused on the definition of higher-grade zones and an infill drilling
programme was designed and initiated.
Atalaya was granted the Unified Environmental Authorisation (Autorización
Ambiental Unificada ("AAU")) by the Junta de Andalucía in March 2023 after
initiating the permitting process in December 2021. Subsequently, Atalaya was
granted the Exploitation and Restoration permits for the Valverde Exploitation
Concession in December 2023 and the water permit in May 2024. The permitting
timeline for PMV highlights that Andalucía is a world-class mining
jurisdiction.
Atalaya plans to access the Masa Valverde and Majadales deposits by
constructing a ramp from surface. Underground mining is expected to be
completed by a mining contractor, which is consistent with other operations
across the Iberian Pyrite Belt including at Sandfire's neighbouring MATSA
mines, and allows Atalaya to benefit from the significant underground mining
skills in the region.
Mined material will then be trucked to Proyecto Riotinto in order to leverage
Atalaya's existing 15 Mtpa processing plant. The copper stockwork-style of
mineralisation is expected to be amenable for processing without requiring
significant investment in plant modifications. This is consistent with
Atalaya's strategy for developing Riotinto into a central processing hub for
its assets across the Riotinto District, thereby facilitating higher
production and a longer life-of-mine at competitive capital intensity and
reduced execution risk.

Ramp
Figure 2 is a plan view of PMV, showing the Valverde Exploitation Concession,
the four orebodies discovered so far (Masa Valverde, Majadales, Campanario and
Mojarra) and the planned ramp to the Majadales and Masa Valverde deposits. The
ramp will also facilitate more efficient exploration of the possible
connection between Masa Valverde and Majadales.

The following set of sections, as shown in Figure 4, illustrate the new assay
results and the geometry of the high-grade zones.
Figure 5: Section A
Section A is located in a sector of the deposit where additional infill
drilling is in progress to improve definition of the high-grade copper
intervals from previous holes.
Figure 6: Section B
Section B illustrates stockwork copper zones which are situated laterally and
under the massive sulphides in the south-west and north-east sectors, and the
polymetallic zinc-rich mineralisation hosted by massive sulphides in the
central part of the deposit.

Figure 9 shows the mineralisation wireframes, copper values above 0.5%, the
planned ramp and the nearby Majadales deposit which will also be accessible
from the planned ramp. The new holes are represented by the thicker black
lines in the diagram.
Next Steps
Two rigs are currently onsite, and it is expected that the ongoing infill
drilling programme will be completed by the end of 2025. In parallel with
drilling, the Company is refining the geological and geometallurgical models
in order to support an updated Mineral Resource Estimate.
Metallurgical test work is also in progress, with the current focus on
high-grade stockwork-type copper material. Future test work is planned for the
polymetallic material including related to the production of zinc concentrates
from areas of high-grade zinc mineralisation, as well as to investigate the
potential recovery of gold from gold-rich mineralisation that is independent
of the copper and zinc mineralisation. Application of the E-LIX System will be
tested in conjunction.
Atalaya is currently finalising the purchase of certain surface rights which
are required to begin development of the ramp portal. Subject to final
approval by Atalaya's Board of Directors, ramp development is expected to
begin in late 2025.
