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.
Figure 2: Plan View of PMV, the Valverde Exploitation Concession and Planned 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.

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.
