(MENAFN- Newsfile Corp) Vancouver, British Columbia--(Newsfile Corp. - August 20, 2025) - EMX Royalty Corporation (NYSE American: EMX) (TSXV: EMX) ( the "Company" or "EMX") congratulates AbraSilver Resource Corp. ("AbraSilver") on its recent updated Diablillos mineral resource estimate ("MRE") that increased total open pit constrained, oxide mineral resources to 199 million ounces of contained silver (+34%) and 1.72 million ounces of contained gold (+27%) in the measured and indicated ("MI") categories.¹,² AbraSilver is also further enhancing project economics with ongoing drilling, advancing other priority initiatives (e.g., engineering optimization, investment incentives, among others), and is expected to receive EIA approval in the latter half of 2025 and on schedule to deliver a definitive feasibility study ("DFS") for the Project in Q1 2026. EMX retains a 1% NSR royalty on the Diablillos Project, and all known mineralization occurs within EMX's royalty ground.

The updated Diablillos MRE reports tank leach resources, which previously was the sole metallurgical processing assumption for the Project, as well as contributions from a maiden heap leach MRE. The additional heap leach resources represent a milestone advancement in converting near surface and peripheral lower grade "waste" material within the constraining open pit configuration to mineralization potentially recoverable via a low-cost processing route. AbraSilver reported total (i.e., tank and heap leach) oxide MI resources as 104 Mtonnes averaging 59 g/t silver and 0.51 g/t gold. The tank leach MI resources account for approximately 70% of the tonnes and over 90% of the contained silver and gold, with the heap leach resources contributing the balance which provides the potential to reduce the strip ratio and enhance project economics.

There were significant MI increases across all five resource deposits (i.e., Oculto, JAC, Fantasma, Laderas and Sombra) (see Figure 1 reference map), with the largest tonnage and contained metal increases driven by the JAC deposit, which is characterized by high-grade, near-surface silver-gold mineralization, as well as the Oculto deposit. The Sombra deposit, a recent discovery immediately south of Oculto and JAC, represents a first-time addition to the Project MRE totals.

There is significant district scale exploration upside at Diablillos with an ongoing Phase V 20,000 meter drill program scheduled for completion by early 2026. This program includes step-out drilling at Oculto East, JAC, and Sombra, as well as exploration drilling at the Cerro Viejo and Cerro Blanco porphyry targets.

EMX congratulates AbraSilver for its success in rapidly building value at the Diablillos royalty property. In addition to the significant increases in silver-gold mineral resources via drilling and metallurgical advancements, AbraSilver is currently evaluating other initiatives to further enhance project economics as inputs to the H1 2026 DFS (e.g., connecting to national grid for power, upgrading the fleet size, outsourcing waste movement, and optimizing TSF design to co-locate waste with tailings).³ Moreover, Diablillos is eligible for Argentina's Incentive Regime for Large Investments (i.e., RIGI), which includes lower tax rates, elimination of export duties, and accelerated depreciation; an investment decision by Q2 2027 is required to fully qualify. Clearly, AbraSilver is on a fast track in advancing Diablillos to a production decision, and thereby unlocking the value of EMX's royalty interest.

Comments on the Updated MRE . The updated Diablillos MRE reports total (i.e., tank and heap leach) measured resources of 33,218 Ktonnes @ 98 g/t Ag (105,050 Koz contained) and 0.59 g/t Au (634 Koz contained) and indicated resources of 70,686 Ktonnes @ 41 g/t Ag (93,593 Koz contained) and 0.48 g/t Au (1,081 Koz contained). In addition, the updated MRE includes total inferred resources of 19,628 Ktonnes @ 21 g/t Ag (13,427 Koz contained) and 0.38 g/t Au (241 Koz contained).

Comments on the December 2024 PFS. AbraSilver's PFS study updated in December 2024 outlined an average 14 year life of mine with annual production of 7.6 Moz of silver and 72 Koz of gold yielding an NPV(5) of US$747 million, 28% IRR, and a two year payback using base case prices of $25.50/oz silver and $2,050/oz gold. Importantly, the PFS production profile over the first five years of full mine production averages 11.7 Moz silver and 59 Koz gold which underlines the Project's early-stage potential for strong cash-flow generation and corresponding royalty payments to EMX. AbraSilver's ongoing initiatives and sustained silver and gold bull market prices suggest significant additional Project upside.
