Base Case: After-tax net present value ('NPV') of $2 billion (US$1.5 billion) at a 7% discount rate, after-tax internal rate of return ('IRR') of 29%, 1.9-year payback period and 29-year life of mine ('LOM')
After-tax NPV of $3.8 billion (US$2.6 billion) at 7%, after-tax IRR of 45% and a 1.4-year payback at spot prices
Phase 1 average annual production of 200,000 ozs Au and 48mm lbs Cu over 5 years, with 157 million lbs Cu Eq. or approx. 307,000 ozs Au Eq. LOM
LOM revenue of 48% copper, 45% Au, and 7% Mo at Base Case prices, and 50% Au, 44% Cu and 6% Mo at spot
Phase 1 operating cash flow of $2 billion at Base Case prices supports rapid payback of 1.9 years and fully funds Phase 2 expansion capex
Among the lowest cost and capital intensity projects relative to peer group
Two-phase approach at single plant site with Phase 1 at 40,000 tonnes per day ('tpd'), doubling to 80,000tpd
NPV of $2.0 billion (US$1.5 billion) is 1.7 times initial capital investment of $1.1 billion (US$847 million) at Base Case pricing and 3.3 times initial capex at spot prices
Phase 1 cash cost of US$763/oz Au Eq. or US$1.49/lb Cu Eq. sits in first quartile globally i
Long-term opportunity spanning 35-kilometer porphyry district
29-year mine plan
New discovery at West Goodspeed, located within 1km of Red Dog, not included in current resource
$7 million fully funded exploration program focused on expanding higher margin and grade northwest corridor

The 2025 PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the projections described in the 2025 PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

U.S. Court of Appeals for the Federal Circuit Affirms Prior Delaware District Court Rulings in Favor of Acadia in NUPLAZID® (pimavanserin) Composition of Matter Patent
- Composition of matter patent affirmed, provides protection into 2030 - Builds on recent ruling in favor of Acadia for formulation patent expiring in 2038 SAN DIEGO, June 09, 2025--(BUSINESS WIRE)--Acadia Pharmaceuticals Inc. (Nasdaq: ACAD) today announced that the U.S. Court of Appeals for the Federal Circuit affirmed a decision issued by the U.S. District Court for the District of Delaware in December 2023 confirming validity of the NUPLAZID® (pimavanserin) '740 composition of matter patent. The affirmance came in Acadia's litigation against MSN Laboratories Pvt. Ltd. and MSN Pharmaceuticals, Inc. In its affirmance, the Appeals Court applied the precedent established in Allergan USA, Inc. v. MSN Laboratories Private Ltd., MSN Pharmaceuticals, Inc., Sun Pharmaceutical Industries Limited, holding that "a first filed, first-issued, later-expiring claim cannot be invalidated by a later-filed, later-issued, earlier-expiring reference claim having a common priority date." "We are gratified that the U.S. Federal Appeals Court has affirmed the lower court's ruling in favor of our composition of matter patent for NUPLAZID, securing protection into 2030 for this patent, and beyond based on the recent favorable ruling for our formulation patent providing patent protection for NUPLAZID 34 mg capsule formulation into 2038," said Catherine Owen Adams, Chief Executive Officer. "These decisions reinforce our commitment to safeguarding the intellectual property that underpins our innovations in addressing serious, unmet medical needs." This follows the U.S. District Court for the District of Delaware ruling in favor of Acadia regarding its '721 formulation patent for NUPLAZID which ruled in favor of Acadia on both infringement and validity arguments in its formulation patent litigation against Aurobindo Pharma Limited and other ANDA (Abbreviated New Drug Application) filers.
