  • 25 Aug 2025 - Gold developer Omai Gold Mines (TSXV:OMG) reported an updated mineral resource estimate (MRE) for its Wenot deposit at its 100%-owned Omai Gold project in Guyana, which more than doubled indicated resources to 3.7 Moz @ 1.82 g/t Au while also growing inferred resources by 16% to 0.97 Moz @ 1.46 g/t. Including the project’s other Gilt Creek deposit, project and company resources gres by ~50% to 6.5 moz. OGM stock was up a few percent today (25 Aug) intraday following this news, to 90c/sh, market cap C$548m, and new market cap/oz of US$61/oz Au - inbetween our 71-company gold developer peer group median $45/oz and mean $66/oz AuEq. Omai’s after-tax NPV5 according to its 2024 PEA (that is now superceded by this substantial resource update), is US$600m, translating to a P/NAV (taken as market cap/NPV) of 0.66x at our refernce gold price of US$2,000/oz - above group mean P/NAV of 0.53x. But a larger NPV to reflect this substantial resource upgrade (and at least one more as 2 rigs continue to aggressively convert inferred resources to indicated) is anticipated by late 2026. Guyana returned to Fraser institutes survey of mining companies this year after being excluded last year, and it moved up +13 spots since the prior year to #9 - just ahead of Norway #10 and just behind Newfoundland #8 and Saskatchewan #7 (as we covered on LinkedIn here: https://www.linkedin.com/feed/update/urn:li:activity:7356864986410844160)
