Burgundy Diamond Mines Limited has released a detailed update on its Ekati Diamond Mine, outlining significant revisions to its life‐of‐mine plan based on new drilling, sampling, and block modelling activities. The company has refined both its Mineral Resource and Ore Reserve estimates across several key areas—most notably in the Misery Main and Fox underground deposits. At Misery Main, recent diamond drilling and increased microdiamond sampling have led to an updated geological model with extended mine depth and modified resource classifications calculated using ordinary kriging on sub‐blocks. Technical parameters such as diamond grade (in carats per tonne), block sizes, and bulk density measurements were used to incorporate more robust grade modelling into the reserve estimates. In the Fox underground deposit, the latest prefeasibility study from 2025 demonstrates improved project economics mainly as a result of switching from incline caving to a sublevel retreat method coupled with a streamlined Railveyor haulage system. This technical adjustment has resulted in lower initial capital outlays and earlier ore release, while detailed production profiles, operating costs, and sensitive financial indicators (such as NPV and IRR) reflect the viability of the revised plan. The announcement also details updated bulk sampling results from the Point Lake and Sable open pit projects, where finer diamond size frequencies have led to lower average prices, prompting a deferment of open-pit mining at Point Lake until mid-2026 while maintaining a contingent stockpile to support plant feed. Moreover, the update reviews environmental measures, infrastructure readiness, permitting pathways, and risk factors including potential delays in regulatory approval and changes in diamond valuation assumptions. Detailed sensitivity analyses show that the project remains commercially robust under moderate shifts in key parameters such as diamond price, grade and operating costs, though it remains exposed to fluctuations in the broader commodity market. Market sentiment may lean bullish given the extended mine life, enhanced mining techniques, and overall strengthening of project economics through new technical insights and cost reductions. At the same time, some caution may be warranted given the inherent risks of integration challenges, regulatory delays, and dependency on stable diamond pricing, all of which are critical factors for investors evaluating the long-term prospects of Burgundy Diamond Mines Limited's operations.
