Covered mining company announcements incorporated into today’s intraday TSX Peer Table (resource updates, economic studies, changes in attributable project ownership):

• 4 Sept 2025 - Copper developer Koryx Copper (TSXV:KYX) announced an updated PEA for its 100%-owned flagship Haib project in Namibia, which replaces a prior 2021 PEA. The study contemplated 28 mtpa conventional milling and 7mtpa low grade heap leach (replacing the 20 mtpa bio-heap leach contemplated in 2021). So capex is obviously up signficantly (to US$1.559b), but the more conventional processes in this study should have much lower technical risk. Reported post-tax NPV8 at US$10,000/t Cu ($4.536/lb Cu) was US$1.742m with low all-in-sustaining costs of $2.46/lb Cu. At our estimated 3-month trailing average copper price of US$4.76/lb Cu, this NPV rises to $2.1b - encouragingly and somewhat surprisingly in-line with the 2021 PEA results at this price, despite the large jump in capex (for the mill). KYX stock traded up +2% today (4 Sept) after this announcement on strong volume, to C$1.05/sh, market cap C$100m, and P/NAV (simplified as market cap/post-tax NPV) of 0.03x - a 55% discount to our 35-company copper developer peer group median 0.08x (at 3-month trailing $4.76/lb).
