The company recently announced significant advancements from its 100%-owned Chidliak Diamond Project, located near Iqaluit, Nunavut, Canada. These positive drilling results underscore the project’s growing potential and confirm the substantial expansion of its high-grade kimberlite resources, particularly the crucial CH-6 kimberlite pipe.
Peregrine Diamonds Unlocks Deeper Potential with Successful Chidliak Drilling Program
The recent drilling campaign, comprising three critical diamond holes, totaled an impressive 1,474 metres, delivering invaluable geological data. This exploration effort was meticulously designed to further delineate the renowned CH-6 kimberlite, aiming to extend its high-grade resource beyond its previously established depths. The outcomes of this program are not just promising; they are transformative for the Chidliak Project, indicating a robust future for diamond recovery in the region.
The Strategic Importance of the Chidliak Diamond Project
The Chidliak Diamond Project has long been recognized as a premier exploration venture in Canada’s diamond landscape. Situated in the pristine and geologically rich territory of Nunavut, Chidliak has consistently yielded encouraging results, positioning itself as a potential major contributor to the global diamond supply. The project is characterized by multiple kimberlite occurrences, with CH-6 standing out due to its consistently high-grade diamond content. Peregrine’s strategic objective has always been to thoroughly understand and expand these resources, leveraging advanced drilling techniques and comprehensive geological modeling.
Operating in the Arctic presents unique logistical and environmental challenges, but the rewards of discovering significant diamond deposits in such a stable jurisdiction are substantial. The successful execution of this drilling program highlights Peregrine’s expertise and commitment to responsible and effective mineral exploration in remote environments.
Detailed Overview of the 2017 Drilling Campaign Results
The 2017 drilling program meticulously targeted key areas within the CH-6 kimberlite pipe to assess its vertical and lateral extent. The three core holes, identified as CHI-050-17-DD36 (DD36), CHI-050-17-DD38 (DD38), and CHI-050-17-DD39 (DD39), provided critical insights into the kimberlite’s geometry and continuity at depth.
Core Hole CHI-050-17-DD36 (DD36): Delineating Kimberlite Plunge and Character
Core hole DD36 was a 378-meter vertical hole, strategically designed to intersect the kimberlite from 4.5 meters to 295.8 meters below surface (mbs). This intersection depth was entirely consistent with the existing resource model for the CH-6 kimberlite, providing an important validation of previous geological interpretations. Beyond simply confirming the presence of kimberlite, DD36 also served a dual purpose: to access kimberlite at 260 mbs and 380 mbs for crucial microdiamond sampling. Microdiamond analysis is a vital early-stage exploration tool that provides critical insights into the diamond potential and characteristics of a kimberlite pipe, guiding future bulk sampling and resource estimation efforts.
Furthermore, the results from DD36 were instrumental in delineating a southward plunge for the northern portion of the CH-6 kimberlite, aligning perfectly with earlier modeling. This refinement of the geological model enhances the understanding of the kimberlite’s intricate subsurface architecture. An intriguing finding from DD36 was the identification of a unique, spatially restricted textural sub-unit of CH-6 kimberlite, designated KIM-G, which was observed at depths ranging from 149 to 189 meters. The presence of distinct kimberlite sub-units can have significant implications for understanding the emplacement history and variability of diamond grades within the pipe.
Core Hole CHI-050-17-DD38 (DD38): Confirming Expansion and Enhancing Resource Potential
Drilled at a -60-degree inclination to a total length of 560 meters (equivalent to 485 mbs), DD38 was specifically planned to provide an east-west intercept of the kimberlite within the critical 260 mbs to 500 mbs depth range. The outcomes from DD38 were exceptionally positive, revealing a substantial 190.2-meter intersection of typical olivine-rich CH-6 kimberlite, spanning from 277 mbs to 442 mbs. This result is particularly significant as it directly confirms and builds upon the in-section result previously reported from DD33, a testament to the continuity and robust nature of the CH-6 pipe.
Crucially, DD38 indicated an expanded in-section diameter for the kimberlite within the CH-6 pipe, measuring 98 meters – notably larger than the 90-meter diameter reported for DD33. This expansion with depth is a key geological indicator, suggesting that the volume of kimberlite, and consequently the potential contained carats, is increasing significantly at deeper levels. Such findings are paramount for future resource calculations and bode well for the overall economic viability of the project.
Core Hole CHI-050-17-DD39 (DD39): Proving Deep Continuity of High-Grade Kimberlite
DD39 was a 536-meter near-vertical hole designed to provide a deep intercept of the known high-grade KIM-L kimberlite from 3.9 mbs to beyond 500 mbs. The hole successfully terminated in kimberlite at 532 mbs, definitively confirming that the CH-6 kimberlite system extends well beyond the 500 mbs mark. This depth extension is a critical achievement, as 500 mbs was the initial planned extent for the 2017 resource expansion drilling program.
The drilling of DD39 primarily intersected the high-grade KIM-L kimberlite throughout its length, with one notable exception: a 32-meter country rock intercept observed between 347 mbs and 379 mbs. This intercept is interpreted as a xenolith – a fragment of host rock engulfed by the kimberlite during its violent ascent. The overall consistency of the KIM-L intersection reaffirms the pipe’s strong continuity and high-grade potential at significant depths, opening up exciting new avenues for future resource growth.
Management Optimism: A Significant Uplift to Contained Carats
Tom Peregoodoff, Peregrine’s President and Chief Executive Officer at the time, expressed immense satisfaction with the drilling results. “We are extremely pleased with the drill results to date,” Peregoodoff commented. His enthusiasm was particularly focused on the confirmation from DD38 regarding the expansion of the CH-6 kimberlite with depth. “This additional kimberlite material could provide a significant uplift to contained carats as we look to recalculate the resource later this year,” he added.
This statement underscores the direct economic implications of the drilling success. An increased volume of kimberlite, especially one known for its high-grade (averaging 2.45 carats per tonne), directly translates to a greater estimated quantity of diamonds within the deposit. The confirmation from DD39 that the high-grade CH-6 pipe continues below 500 meters further solidifies “future resource expansion opportunities,” pushing the boundaries of the project’s known potential. With drilling ongoing, Peregoodoff affirmed confidence in meeting the year’s objective of expanding the CH-6 resource below the 260 mbs base of the current Inferred Resource, signaling a strategic move towards upgrading and enlarging the project’s overall diamond inventory.
Implications for Chidliak’s Future and Global Diamond Supply
The successful 2017 drilling program at Chidliak represents a pivotal moment for Peregrine Diamonds and the Canadian diamond industry. The proven expansion of the CH-6 kimberlite, both in lateral extent at depth and its overall vertical continuity, enhances the project’s fundamental value proposition. This is not merely about finding more kimberlite; it’s about confirming the persistence of a high-grade, diamond-bearing body that promises longevity and economic viability.
The increased volume of kimberlite at greater depths means that the project has a larger potential “pay zone.” This can lead to a more robust and longer mine life once production commences. For investors and stakeholders, this translates into reduced risk and increased confidence in Chidliak’s long-term production profile. The geological models will be updated with this new data, allowing for a more precise and comprehensive resource recalculation, which is expected to show a significant increase in total contained carats.
Beyond the immediate resource implications, these results reinforce Nunavut’s growing importance as a frontier for diamond exploration. Canada has already established itself as a significant player in the global diamond market, and projects like Chidliak further solidify this position. The ability to successfully explore and delineate substantial resources in the challenging Arctic environment speaks volumes about the technological advancements and human ingenuity within the Canadian mining sector.
Looking Ahead: Continued Exploration and Resource Development
The momentum generated by these positive drilling results will undoubtedly propel further exploration and development activities at the Chidliak Project. The company will now focus on integrating this new data into its resource models, which will be critical for updating the mineral resource estimate later in the year. This updated estimate will provide a clearer picture of the project’s true potential and guide future investment decisions, including potential pre-feasibility and feasibility studies.
The commitment to expanding the CH-6 resource below the 260 mbs base of the current Inferred Resource also suggests a strategic intent to upgrade portions of the resource to higher confidence categories (e.g., Indicated or Measured), which are crucial for defining economic reserves. Peregrine Diamonds’ meticulous approach to exploration, coupled with these encouraging discoveries, positions the Chidliak Diamond Project as a bright prospect in the future of global diamond mining.
In conclusion, Peregrine Diamonds Ltd.’s latest drilling campaign at the Chidliak Diamond Project has yielded exceptionally positive results, confirming a significant expansion of the high-grade CH-6 kimberlite. These findings not only promise a substantial uplift to the project’s contained carats but also open up exciting new avenues for future resource growth and contribute to the enduring legacy of diamond exploration in Canada’s Arctic.
