Infill assays are reported as materially higher than both the Indicated grade of 1.18 g/t and the Inferred grade of 1.72 g/t across the zone

Decision Focus

On July 22, 2026, Talamore Mining Corporation released assay results from 55 reverse circulation holes at the Supremo Extension zone of its wholly-owned Coffee Gold project in Yukon, Canada. The results are feeding directly into an ongoing Feasibility Study, with approximately 20,000 metres of infill drilling completed ahead of the resource update cutoff. For Mining Operations Directors, the operational signal is not the headline intercepts themselves but what grade performance at depth means for the eventual pit design, strip ratio, and heap leach sequencing of a 3.8-million-ounce open-pit project approaching a construction decision.


90-Second Brief

This week, talamore’s 40,000-metre infill and exploration program at Coffee Gold is targeting resource conversion from Inferred to Indicated at Supremo Extension ahead of a feasibility study cutoff. Infill assays are reported as materially higher than both the Indicated grade of 1.18 g/t and the Inferred grade of 1.72 g/t across the zone. The broader project carries 3.0 million ounces in Measured and Indicated resources plus 0.8 million ounces Inferred. With permitting and engineering described as near-final and a construction decision targeted, the resource upgrade work is already shaping the pit parameters and metallurgical domain split that any incoming operations team will inherit at construction sanction.

What Is Really Happening?

The Supremo Extension zone sits at the intersection of a steep northeast-trending high-grade structure and a shallow east-dipping zone. That structural geometry is not incidental to operations planning: the shallow-dipping zone delivers wider mineralised intervals with lower trace metals, while the intersection creates thick, high-grade blocks described as well-suited to open-pit mining. Infill drilling is filling cross-sections between existing drill lines to give the resource model the density required for Indicated classification.

The practical consequence of grades exceeding the resource average is that block grades in the feasibility model should improve, with potential to reduce the strip ratio and justify pit expansion at depth. Several holes have intercepted mineralisation below the current pit shell, raising the prospect of a deeper or wider pit outline before the feasibility study locks in the mine plan. That decision will set the waste push schedule, bench progression, and fleet sizing that an operations director will be accountable for from day one.

The heap leach recovery parameters are equally consequential. The project’s metallurgical domain split is approximately 64% oxide, 18% upper transition, 5% middle transition, and 13% lower transition, with recoveries declining from 86.3% for oxide to 31.4% for lower transition material. Any operational model that assumes resource-average recovery will overstate metal production once the ore blend shifts toward transition material as the pit deepens. The domain breakdown here is explicit enough for an operator to identify where recovery management will matter most in years three through five of production.


Why It Matters for Mining Operations Directors

A project at this stage rarely requires direct attention from an operating-mine director. What warrants a second read is the combination of scale, design type, and timeline. At 3.8 million ounces across Measured, Indicated, and Inferred categories, Coffee Gold sits at a size that will require experienced operational leadership at construction sanction, not just at first ore. Permitting and engineering described as near-final suggests a construction decision horizon within a plausible two-to-three-year window, though no schedule has been confirmed.

The open-pit heap leach design carries a specific operational profile: lower capital intensity than a mill, but a production ramp dependent on stacking rate, pad management, and solution management across a long ore campaign. The recovery differential between oxide and transition domains means domain sequencing and reagent management matter as much as head-grade management. Any operator reviewing this project for a leadership role should stress-test the feasibility mine plan against the transition-material recovery assumptions before accepting commitments on first-year metal targets.

The Yukon location adds operational constraints that do not appear in the resource numbers. Remote infrastructure, a FIFO workforce model, and four established First Nation groups with stated interests in land and water outcomes all represent lead-time requirements that a startup team will need to absorb before steady-state production is achievable.


Forward View

The immediate watch point is the resource update incorporating the 2026 infill data, which will feed into the Feasibility Study and establish revised pit shells, strip ratios, and reserve-level economic parameters. If the updated model confirms grade improvement at depth and supports pit expansion, the capital estimate and mine schedule will shift accordingly, changing the operational envelope that an incoming director will need to manage.

Beyond feasibility, the permitting timeline in Yukon is the gating factor for construction sanction. Environmental approvals and First Nation consultation outcomes are not reducible to schedule assumptions, and operators experienced in remote Canadian projects will understand that community and regulatory processes can extend construction-ready timelines by years without reflecting on the asset fundamentals.

A third signal worth tracking is the company’s planned shift to regional targets in August 2026. If those targets return material mineralisation, mine plan complexity increases alongside the resource opportunity, with direct implications for fleet sizing, infrastructure phasing, and the operational model presented to construction decision-makers.


What Is Still Uncertain

No confirmed construction timeline or capital cost estimate is publicly available as of this release. The feasibility study is ongoing, and the resource update incorporating 2026 infill data has not yet been published. The directionally positive gap between current Inferred resource grades and infill assay performance has not been formally converted into a revised resource statement. Pending assays on multiple cross-sections mean the final pit geometry remains open. Recovery assumptions for transition material carry inherent uncertainty at this stage, and no metallurgical testwork update accompanied this release. Whether the project proceeds to construction sanction also remains contingent on permitting outcomes not yet confirmed.


One Question for Your Team

If the Coffee Gold feasibility study delivers a construction decision within the next two years, which operational lead times in remote Yukon — workforce sourcing, equipment delivery, First Nation engagement sequencing, and heap leach pad commissioning — would your team need to start tracking now to be ready for a first-ore commitment?
