Atalaya Mining Copper, S.A. Announces Results from Its Ongoing Drilling Programme At Proyecto Masa Valverde Atalaya Mining announced 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. 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. Recent infill and ext extensional drilling at the Mas a 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. 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 Andalucia 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 ramp will also facilitate more efficient exploration of the possible connection between Masa Valverde andajadales. Duyuru • Jun 25
