DLP puts a number on Aurora: $2.7B NPV, and a moly project in disguise

On September 1, 2026, DLP Resources published its first economic study — a Preliminary Economic Assessment, or PEA, the earliest and roughest pass at whether a deposit could make money — for its Aurora copper-molybdenum-silver project in Peru’s Cusco province. The headline numbers are large: an after-tax net present value of US$2.7 billion (the project’s estimated worth today at an 8% discount rate) and an 18.5% internal rate of return, the yearly percentage a project earns back on the cash sunk into it. The study was prepared by three engineering firms — Global Resource Engineering, Ausenco, and SRK Consulting — under Canada’s NI 43-101 rules. The market had already moved: DLP’s shares are up 127.8% over three months while copper barely budged (+0.8%) and the copper-equity peer index rose 0.9%. That’s pure company-specific re-rating, not a sector wave.

Here’s the mechanism worth understanding. Aurora is really a molybdenum project wearing a copper name. Molybdenum — a steel-hardening metal — supplies 65.6% of lifetime revenue, and the underground grade averages 0.20% (peaking at 0.25%), which is genuinely world-class for moly. Copper, at 0.19% grade, is the low-grade porphyry backdrop that carries the tonnage. And the tonnage is huge: 1.73 billion tonnes of total resource. The returns, though, are thin for the money involved. The upfront build is priced at US$2.377 billion, so the NPV covers initial capital only 1.14 times — a slim cushion. Against that stands a company with a market value near C$39–40 million and no strategic partner disclosed. CEO Ian Gendall, a 32-year exploration geologist who identified Aurora in 2021, has no prior record of taking a deposit to feasibility, production, or a sale.

Now the honest part. Most of the resource — 1,118.8 million tonnes of 1,733 million — is Inferred, the most speculative category, which NI 43-101 says is too uncertain to have economics applied; the PEA carries this material anyway, and no reserves are declared. The mine plan uses only about 30% of the resource. The much-promoted multi-phase underground expansion is explicitly un-costed and unevaluated — no economics applied. And with 65.6% of revenue tied to molybdenum, a thinly traded, cyclical metal, the economics live or die on price. The community land-use agreement runs only to about 2032. What’s next: the full technical report filed on SEDAR, an infill and extensional drill program toward pre-feasibility, and a maiden 3,000-metre drill program at the Esperanza copper-gold project in late Q3 2026.
