“The results of the Aurora PEA confirm what our geological and technical work has long suggested: this is a copper-molybdenum-silver deposit with the scale, grade and production profile to support compelling development pathway. The PEA demonstrates robust cashflows, competitive operating costs, reasonable capital costs and robust financial returns, including an after-tax NPV8% of $2,703 million and an 18.5% IRR with substantial upside leverage to rising copper and molybdenum prices. Importantly, this PEA represents only the first chapter of the Aurora story, reflecting 402.9 million tonnes of mineralized material, or approximately 30% of the MRE, which shows an Indicated resource of 614.84 million tonnes at 0.19% Cu, 0.06% Mo and 2.09 g/t Ag and an Inferred resource of 1,118.80 million tonnes at 0.18% Cu, 0.07% Mo and 1.95 g/t Ag. As such, a significant portion of the MRE has not been included in the PEA, preserving future underground expansion optionality beyond what is contemplated within this initial 17.5-year mine plan. We intend to advance Aurora towards pre-feasibility while simultaneously scoping the underground expansion optionality and look forward to engaging with strategic partners on this multi-phase development program,” commented Ian Gendall, CEO of DLP.

Project Overview

The 100%-owned Aurora spans 12,500 hectares in Peru’s Cusco province, with easy road access and power infrastructure nearby. On June 22, 2026, DLP announced that the local Parobamba Community, where Aurora is located, approved a six-year extension of the land use and exploration agreement, demonstrating the strong, collaborative relationship DLP has built with the local community and providing the Company with the long-term access and social license to advance the project through its next stages of development.

The PEA represents an initial development case for Aurora, deliberately designed to maximize after-tax returns and capital efficiency on initial invested capital. The PEA mine plan encompasses 402.9 million tonnes of mineralized material, representing approximately 30% of Aurora’s MRE, concentrating the initial 17.5-year mine plan on the highest-confidence, highest-value portions of the deposit accessible by open pit and underground mining methods. The resources outside of the mine plan define a clear expansion opportunity. As such, the Company intends to advance an infill and extensional drill program at Aurora to advance resource classification and support incorporation of material outside of the mine plan into subsequent Prefeasibility or Feasibility studies. Management views this PEA as an initial Phase 1, providing a foundation for a long-term, multi-decade mining district, with today’s mine plan representing the first of several possible development phases. The PEA establishes Aurora as one of Peru’s emerging copper-molybdenum-silver development assets, with a project profile characterized by a long-life, high-value molybdenum production base alongside meaningful copper and silver co-production.

The Company notes the PEA is preliminary in nature and there is no certainty that the PEA will be realized. The PEA includes Inferred Mineral Resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The Company also notes that a multi-phase underground development scenario has not been evaluated in the current PEA, no economic analysis has been applied to potential additional resources, and there is no certainty that any multi-phase underground expansion would be realized. DLP views the multi-phase underground expansion opportunity as a significant source of longer-term value not captured in the PEA economics and intends to advance dedicated multi-phase underground scoping work as a priority workstream.

Mining Methods

The mine plan consists of two principal mining methods: a conventional truck-and-shovel open pit operation to year 4 of the mine life (including stockpiling mineralized material), followed by underground mining of the higher-grade molybdenum core between years 3 and 17. Underground mineralized material will be processed alongside stockpiled open pit material.

Open Pit Mining (Years -3 to 4)

The open pit mine plan is based on a conventional truck-and-shovel operation producing a total of 237.3 million tonnes of mineralized material at a design throughput of 65,000 tonnes per day. The open pit strip ratio of 0.95:1 (waste:mineralized material) reflects the favorable geometry and continuity of the near-surface mineralized body. The open pit mine plan will see average mined grades of 0.33% copper, 0.01% molybdenum and 3.52 g/t silver.

Underground Mining (Years 3 to 17)

Following completion of open pit mining, operations transition to underground extraction of the higher-grade molybdenum-enriched core of the Aurora deposit. Underground development commences simultaneously with the opening of the open pit mine, using a block cave mining method, with level access established during late open pit years. The underground mine plan will see 165.6 million tonnes mined at an average molybdenum grade of 0.20% Mo, positioning Aurora as a robust, high grade molybdenum project.

Updated Mineral Resource Estimate

In connection with the PEA, an updated MRE has been completed for the Aurora deposit by Terre Lane of Global Resource Engineering, an independent Qualified Person as defined by NI 43-101. The MRE has an effective date of April 30, 2026. The updated MRE incorporates data from 28 drill holes totaling 22,613.38 metres and reflects revised geological modelling, updated metallurgical recovery assumptions, and the incorporation of recent infill drilling results.

The MRE is classified in accordance with the 2014 CIM Definition Standards on Mineral Resources and Reserves and was estimated in accordance with the CIM 2019 Best Practices Guidelines. The resource has been constrained by an open pit shell (OP domain) or by a conceptual underground extraction envelope (UG domain) demonstrating reasonable prospects for eventual economic extraction.

QP Disclosure

The geological setting, mineralization, deposit characterization, exploration, drilling, sampling, analytical information, and data verification were prepared under the direction of Hamid Samari, Ph.D., QP, Principal Geologist at GRE. Dr. Samari meets the requirements for a QP as set out in his Certificate of Qualified Person.

Dr. Samari reviewed and verified the data supporting the Mineral Resource Estimate, including the geological and drillhole database, sampling information, analytical data, QA/QC results, and supporting documentation. As part of the data verification, Dr. Samari conducted a site visit to the Aurora Project on June 2-3, 2026, during which he reviewed the project geology, drill core, core logging and sampling procedures, and other relevant geological information. Independent check samples were collected and submitted for laboratory analysis. The copper (Cu), silver (Ag), and molybdenum (Mo) assay results obtained from the independent check samples were compared with the corresponding assay results reported in the project database. The comparison showed reasonable agreement between the two sets of results and provided additional verification of the analytical data supporting the Mineral Resource Estimate. Based on these verification procedures, Dr. Samari considers the data and information used to support the Mineral Resource Estimate to be sufficiently reliable for this purpose. No material limitations on the verification process or material failures to verify the data were identified.

Processing & Metallurgy

The Aurora PEA contemplates a conventional milling and froth flotation process plant designed to treat 65,000 tonnes of mineralized material per day. The process plant is designed to produce a copper concentrate grading approximately 25% Cu and a molybdenum concentrate grading approximately 55% Mo.

Metal recoveries to concentrate average 85.5% for copper, 88.5% for molybdenum, and 74.0% for silver. Silver reports to the copper concentrate as a by-product credit. The recoveries take into account mineralized material from various zones and the blending of various zones to feed the plant. Payable metal assumptions applied in the economic analysis reflect smelter and refinery terms of 96.5% payability for copper and 96.0% payability for molybdenum and silver.

Tailings from the flotation circuit will be filtered and placed in a drystack tailings facility and managed in accordance with applicable Peruvian regulatory requirements, including the standards established under the Environmental Impact Assessment (EIA-d) process overseen by Peru’s Ministry of Energy and Mines (MINEM). The Company is evaluating tailings storage facility design options as part of ongoing engineering studies.

Capital & Operating Costs

Initial capital is estimated at $2,377 million over a 3-year construction period, and is based on the costs outlined in Table 3, below:

Table 3) Breakdown of Initial Capital

Sustaining and underground development capital over the life of mine (through year 20) is estimated at $1,160 million, with total closure costs estimated at $121M.

Working capital of $24.7 million in year 1.

Operating costs are estimated at $13.05/t processed based on the costs outlined in Table 4, below.

Table 4) Breakdown of Operating Costs

Life of Mine C1 cash costs are calculated on a co-product basis: $0.90/lb copper; $7.83/lb molybdenum. Stockpiled material costs (during the pre-production period) have been excluded from the C1 cash cost and included in the pre-production capital cost.

Economic Analysis Results

The PEA highlights an after-tax NPV8% of $2,703 million corresponding to an IRR of 18.5% and a 5.2-year payback period. Assumptions, including commodity pricing used as part of the economic analysis is outlined in Table 6 below:

Table 5) Commodity Price Assumptions

Table 6) Sensitivity to Copper and Molybdenum Prices, Capital Cost and Operating Cost

Infrastructure & Site Layout

The site layout incorporates the process plant, tailings and waste management facilities, camp infrastructure, and water management systems within a consolidated footprint designed to support efficiency. Tailings are planned to be managed in a dry stack tailings facility (DSTF) and potential acid generating (PAG) waste rock storage facility (WRSF), utilizing favourable topographic conditions adjacent to the process plant site. The tailings and waste management facilities have been designed and sited with the long-term development potential of the Aurora deposit in mind, and the selected footprint provides a foundation from which future expansion capacity could be developed as the project advances. The Company will continue to refine site layout and infrastructure design as it advances Aurora toward a Pre-Feasibility Study.

Figure 4) Site Layout

Opportunities

The PEA mine plan has been deliberately designed to deliver the optimal after-tax return on initial invested capital. By focusing the first phase of development on the highest-value portions of the Aurora deposit, the Company has structured the mine plan as a compelling, financeable standalone project while simultaneously preserving the potential for future phases to capture the full resource potential of the Aurora deposit.

This disciplined, phased development philosophy is consistent with practices adopted at analogous large-scale porphyry copper-molybdenum development projects. DLP believes this approach at Aurora appropriately sequences capital deployment to maximize shareholder value at each stage of development.

Multi-phase Expansion Potential

Aurora’s envisioned mine plan is contemplated as an approximate 30% subset of the Indicated and Inferred MRE. DLP views the resources outside of the mine plan, together with additional exploration targets as the natural foundation for multi-phase underground expansion, which the Company expects to advance through dedicated infill and conversion drilling and scoping studies in parallel with PFS activities. Subject to resource conversion, engineering studies, and regulatory approvals, a multi-phase development scenario has the potential to materially extend Aurora’s mine life and increase annual production rates beyond the current Phase 1 PEA.

As illustrated in Figure 5, mineralization at Aurora extends well beyond the boundaries of the Phase 1 mine plan, with the deposit remaining open to the west, east, and at depth. The current MRE boundaries are defined by drilling extent rather than geological limits, and all mineralized zones shown in the section, including lower-grade material at the margins, carry positive economic margins above projected operating costs.

A key feature of Aurora’s long-term value proposition is the infrastructure leverage inherent in a phased development approach. The 65,000 tonne-per-day processing facility constructed under the Phase 1 capital program represents the single largest infrastructure investment required to bring the project into production. Advancing a potential Phase 2 underground expansion would require a materially lower incremental capital outlay, concentrated primarily on underground development and a new dry-stack tailings facility, while utilizing the processing infrastructure already in place. DLP intends to advance an infill and extensional drilling program to further define Aurora’s resource base and support economic evaluation of a future Phase 2 expansion, with Phase 2 scoping work expected to advance in parallel with ongoing Phase 1 development studies.
