DLP Resources Inc. has delivered a base-case after-tax net present value at an 8% discount rate of $2,703 million, an after-tax internal rate of return of 18.5%, and a 5.2-year payback period for the Aurora Copper-Molybdenum-Silver Project in Peru.

The Preliminary Economic Assessment outlines a 17.5-year mine life processing 402.9 million tonnes of mineralized material at a design rate of 65,000 tonnes per day. The development plan uses a phased approach, starting with a 7-year open pit operation with a 0.95:1 strip ratio before transitioning to a 15-year underground block cave phase. Initial capital costs are estimated at $2,377 million, with sustaining and underground development capital projected at $1,160 million and closure costs at $121 million.

The study anticipates average annual production of 90.5 million pounds of payable copper, 37.4 million pounds of payable molybdenum, and 1.21 million ounces of payable silver based on long-term metal price assumptions of $4.90 per pound for copper, $25.40 per pound for molybdenum, and $45.30 per ounce for silver. Under spot pricing conditions as of August 26, 2026, using $6.47 per pound copper, $33.57 per pound molybdenum, and $68.50 per ounce silver, the after-tax net present value rises to $4,812 million with a 24.9% internal rate of return and a 3.8-year payback.

The PEA incorporates an updated Mineral Resource Estimate prepared by Global Resource Engineering with an effective date of April 30, 2026. The resource comprises an indicated resource of 614.84 million tonnes grading 0.19% copper, 0.06% molybdenum, and 2.09 grams per tonne silver, alongside an inferred resource of 1,118.80 million tonnes grading 0.18% copper, 0.07% molybdenum, and 1.95 grams per tonne silver.

This compares with the company's previously reported maiden inferred resource of 1.05 billion tonnes at 0.44% copper equivalent. The current mine plan utilizes approximately 30% of the total mineralized material within the updated resource, leaving the remainder to support future expansion.

DLP secured 100% ownership of Aurora on June 22, 2026, after completing all commitments under the SMRL Parobamba II option agreement, following a six-year land use and exploration agreement extension granted by the local Parobamba Community.

“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.”

— Ian Gendall, CEO of DLP

The company will file a National Instrument 43-101 technical report for Aurora on SEDAR+ within 45 days. Near-term work streams will focus on initiating pre-feasibility study planning—including infill and geotechnical drilling, metallurgical testwork, and engineering trade-off studies—while advancing dedicated scoping work for multi-phase underground expansion.
