Mt Olympus Gold Project Poised for Major Underground Expansion
Kalamazoo Resources has delivered compelling news for investors, revealing a significantly enhanced underground resource at their flagship Mt Olympus project. The company has identified a re-optimised underground resource of 1.44 Mt @ 3.76 g/t Au for 174,500oz, utilising a conservative gold price of AUD$4,500/oz.
This represents a substantial upgrade from previous assessments and positions the project for extended mine life well beyond the current open pit development plans. Furthermore, the Kalamazoo Resources Mt Olympus expansion demonstrates exceptional potential for value creation through systematic resource development.
Substantial Resource Growth Drives Multi-Year Production Vision
Beyond the confirmed resource, Kalamazoo Resources Mt Olympus expansion includes an Underground Exploration Target of 2.0-6.0Mt @ 2g/t Au containing between 129,000-387,000oz (mid-point 258,000oz). This exploration target sits directly beneath the proposed Mt Olympus-West Olympus open pit shell.
Combined with the 772,000oz already within the optimised pit shell, this discovery potentially adds 300,000-560,000oz of additional mineable material to the project's inventory. Moreover, the higher grade nature of this material significantly enhances project economics.
Key Investment Highlights:
- 174,500oz confirmed underground resource at 3.76 g/t Au
- 258,000oz mid-point exploration target beneath the open pit
- Higher grade Indicated material at approximately 4 g/t Au
- Q4 2025 open pit scoping study completion
- Q1 2026 targeted drilling programme to upgrade resource confidence
Executive Chairman Luke Reinehr stated: "The identification of potentially ~300,000-560,000oz of additional mineable underground material below the proposed Mt Olympus open pit, provides a tremendous opportunity to enhance the future open pit production profile."
What Are Underground Exploration Targets?
An Underground Exploration Target represents a preliminary estimate of potential mineral resources that requires additional drilling to confirm continuity and orientation. Unlike established resources, exploration targets are conceptual estimates based on existing geological understanding and drilling data.
Investor Implications:
Underground exploration targets serve as critical indicators of potential resource growth beyond current confirmed estimates. These preliminary assessments provide insight into the geological continuity at depth and demonstrate a systematic approach to resource development.
Additionally, they offer a clear pathway for resource upgrades through targeted drilling programmes. This approach allows companies to communicate potential upside whilst maintaining appropriate technical disclosure standards.
Technical Framework
The exploration target utilises the same geological system as confirmed resources, providing reasonable confidence in the geological model. However, additional drilling remains necessary to meet JORC Resource standards.
In the case of the Kalamazoo Resources Mt Olympus expansion, the Underground Exploration Target benefits from extensive historical mining data and geological understanding. The project produced 350,000oz between 1998-2004, providing valuable geological and metallurgical insights that support current exploration activities.
Strategic Development Timeline and Next Steps
Kalamazoo has established a clear progression pathway for maximising the Mt Olympus project value. The company's systematic approach focuses on converting lower-confidence Inferred material into higher-confidence Indicated resources.
Immediate Priorities (Q4 2025 – Q1 2026):
- Complete Mt Olympus-West Olympus Scoping Study in Q4 2025
- Finalise designs and permits for high-priority exploration drilling programme
- Commence infill drilling in Q1 2026 to convert Inferred to Indicated resources
- Advance Pre-Feasibility Study subject to positive scoping study results
Medium-Term Development:
- Resource growth drilling for underground and open pit optimisation
- Stakeholder and regulatory engagement advancement
- Integration of additional study results from Peake and Zeus deposits
- Greenfields exploration across the broader 380km² project area
Management anticipates this process may result in fewer overall ounces at substantially higher grades, potentially improving project economics. The Kalamazoo Resources Mt Olympus expansion timeline reflects industry best practices for resource development.
