Denarius Metals Granted the "Cruzadillo" Investigation Permit near Its Lomero Project, Huelva Province, Andalusia, Spain

• The Cruzadillo Investigation Permit is located near the Lomero Project and covers approximately 60 hectares

• Denarius Metals' area permitted for exploration in the Iberian Pyrite Belt now covers a total of approximately 665 hectares

• Cruzadillo increases the exploratory potential for expansion of our Lomero Project

Toronto, Ontario--(Newsfile Corp. - September 29, 2025) - Denarius Metals Corp. (Cboe CA: DMET) (OTCQX: DNRSF) ("Denarius Metals" or the "Company") announced today that the Ministry of Industrial Policy and Energy of Huelva, Andalusia has granted the Company the exploration permit for the Cruzadillo claims (the "Cruzadillo Investigation Permit", Figure 1) which are located less than 1 km from the Company's 100%-owned Lomero Project. The Cruzadillo Investigation Permit covers an area of approximately 60 hectares and brings Denarius Metals' total property holdings in the Iberian Pyrite Belt ("IPB") to approximately 665 hectares.

Serafino Iacono, Executive Chairman of Denarius Metals, commented, "The granting of the Cruzadillo Investigation Permit expands our property holdings in the mineralized trend of the IPB. This new property hosts a combination of geophysical anomalies associated with gossan outcrops that supports the potential for the discovery of additional polymetallic deposits. Our team is currently designing the next phase of systematic exploration activities and drilling campaign to be carried out in 2026 at the Lomero Project, including the Cruzadillo area."

Significance of the Cruzadillo Investigation Permit

"Cruzadillo" is crossed by the potential western extension of the Las Merinas target, which lies along a major shear zone discovered in 2022 by field mapping and supported by geophysics anomalies, located south of the shear zone hosting the Lomero-Poyatos deposit and both trending E-W. The shear zone that crosses "Cruzadillo" is delineated by spotted outcrops of gossan such as at Lomero and Las Merinas, with associated evidence of old mining workings (Las Merinas W prospect) and a former mine, named Maria Mine, adjacent to the old Cruzadillo Mine, now covered by the waste from the San Telmo Mine (Santa Barbara Open pit), (Figure 1).

The mineralization originally mined at the Cruzadillo Mine consisted of three ore lenses. Mining began with Bede Metal Corporation in 1882, in a 280 x 40 m cut, likely exploiting the gossan zone and a secondary enrichment to a depth of 27 m. Open-pit mining was halted in 1892. A 1917 map shows two levels of underground exploration in which the lens terminated at depth with metric-sized bands of massive sulfides (probably hosted by semi-massive sulfides). Around 1915, a 50 m deep exploration shaft was constructed east of the main shaft. A drift from this exploration shaft, at a level of 27 m, led to the discovery of four lenses in an area not previously mined or recognized. This work extended into the 1960s, leading to the definition of an area of mineralization east of the shaft, and some historical drilling in the early 1970s.

The Cruzadillo Investigation Permit is important to Denarius Metals because it also provides the Company with legal coverage by preferential right over the land between "Cruzadillo" and the Company's existing investigation permits, Rubia and Palomarejo. Through this legal coverage, referred to as "Demasias", the Company has influence over an additional 141 hectares within the IPB (Figure 2).

In the coming months, the Company will complete the design of the forthcoming drilling campaign for the Lomero Project to be carried out in 2026, including definition drilling targets at Cruzadillo to test for the presence of polymetallic bodies that have the potential to increase the current mineral resources of the Lomero Project.
