  • 20 Oct 2025 - Gold explorer Kalamazoo Resources (ASX:KZR) announced a re-optimized gold resource estimate for its Mt Olympus deposit, which makes up the overwhelming majority of ounces at the flagship Ashburton gold project in Australia. This re-optimization was repiorted to have increased Mt Olympus overall grade by 10% to 2.8 g/t Au and the indicated category ounces by 68%, with the pit-optimized portion now standing at 0.772Moz @ 2.53g/t Au and underground portion now at 0.1745Moz @ 3.76 g/t, with a new UG exploration target of 2-6Mt @ 2g/t for another 129-387koz. Total project resources fall slightly to 1.31 Moz Au (from 1.44Moz), but are now higher-grade and tighter, which should bode well for the upcoming Scoping Study due before yearend, and set to contemplate a high-grade open pit production scenario for the pit-constrained 0.772Moz @ 2.53 g/t Au. KZR traded down today (20 Oct) following this news some -2.4% (outshining peer group median down -4.6%) to 20c/sh, market cap A$47m, and market cap/oz resource of US$23.4/oz - a 51% discount to our 92-company peer group median $48/oz (and a 61% discount to our 74-company gold developer peer group, where KZR is headed upon completion of Scoping Study).
