The Ekati diamond mine is a diamond mining operation in Canada's Northwest Territories, roughly 300 kilometers northeast of Yellowknife, that opened in 1998 as Canada's first diamond mine. Built around a cluster of kimberlite pipes near Lac de Gras, Ekati's discovery and development launched Canada as a major diamond-producing nation and remains one of the most-referenced names in natural diamond provenance today.
This guide goes deep specifically on Ekati — its discovery, its remote subarctic operating environment, how the mine itself is structured, who has owned and operated it over the decades, why it matters historically, and how Ekati-origin diamonds show up in the wholesale trade as a documented-provenance product. For a broader look at Canada's diamond mining industry as a whole, including Ekati's place alongside Canada's other producing mines, that's covered in a separate guide; here, the focus stays on Ekati itself.
The Discovery That Started It All
Ekati's story begins with two geologists, Chuck Fipke and Stewart Blusson, who spent years in the late 1980s and early 1990s tracing kimberlite indicator minerals across northern Canada. Kimberlite indicator minerals — small garnets, chromites, and other distinctive mineral grains that erode out of diamond-bearing kimberlite pipes and get carried away by glacial movement — act as a kind of geological breadcrumb trail. By systematically sampling soil and stream sediment across a huge stretch of the Northwest Territories and mapping where indicator mineral concentrations increased, Fipke and Blusson worked backward toward the source.
That work led them to Lac de Gras, a remote lake roughly 300 kilometers northeast of Yellowknife in Canada's Northwest Territories. In 1991, drilling confirmed diamond-bearing kimberlite at the site — a discovery that triggered one of the largest mineral-claim staking rushes in modern Canadian history, as prospectors and mining companies scrambled to acquire ground across the region on the strength of the find. At the time, Canada had no operating diamond mines and little history as a diamond-producing country, so confirmation of a genuinely diamond-bearing kimberlite field in the Northwest Territories was a landmark event in itself, years before any stone was actually mined and sold.
From Discovery to Mine: Opening in 1998
Turning a confirmed kimberlite discovery into an operating mine took years of further exploration, bulk sampling, environmental assessment, and infrastructure planning — unsurprising given how remote and undeveloped the Lac de Gras area was at the time. The Ekati mine officially opened in 1998, becoming Canada's first operating diamond mine. That milestone is significant beyond Ekati itself: it proved that a viable, commercial-scale diamond mining industry could exist in Canada at all, something that had been genuinely uncertain before Fipke and Blusson's discovery. Every diamond mine that has opened in Canada since has, in a real sense, followed the trail Ekati blazed both geologically and in terms of establishing the regulatory, logistical, and investment precedent for northern Canadian diamond mining.
Ekati's opening is frequently cited alongside the later opening of the nearby Diavik mine as the beginning of what's sometimes called Canada's "diamond rush" — a period in which Canada rapidly went from having no diamond production at all to becoming one of the world's significant diamond-producing countries within roughly a decade.
Where Ekati Is, and Why That Location Matters
Ekati sits in a genuinely remote part of the Canadian Arctic, in the Northwest Territories near Lac de Gras, well north of Yellowknife and far from any permanent road network for most of the year. This location is not incidental to understanding the mine — it shapes nearly every operational decision Ekati makes, from how equipment and fuel arrive on site to when heavy freight can move at all.
For a large portion of the year, Ekati depends on aircraft for personnel and priority freight, since there is no permanent all-season highway connecting the site to southern supply chains. During the coldest winter months, temporary ice roads are constructed across frozen lakes and tundra, creating a narrow seasonal window — typically only a matter of weeks — during which heavy equipment, fuel, and bulk construction materials can be trucked in over the frozen ground and ice. Missing that window can mean waiting an entire additional year for certain deliveries, which makes long-range logistics planning an unusually central part of running a mine like Ekati compared to mines with year-round road or rail access.
This subarctic operating environment also means extreme seasonal temperature swings, permafrost conditions that affect everything from building foundations to tailings and waste-rock management, and a workforce that operates on rotating fly-in, fly-out schedules rather than living locally, since there is no nearby town of meaningful size. These are genuine operational tradeoffs of mining in one of the most remote industrial sites in North America, not incidental trivia — they are a large part of why Ekati diamonds carry a certain mystique in the trade, and why northern Canadian diamond mining in general is viewed as logistically demanding compared to mining in more temperate, better-connected regions.
How the Ekati Mine Is Structured
Ekati is not a single pit but a cluster of multiple kimberlite pipes spread across its claim area, each representing a distinct volcanic diamond-bearing structure that intruded into the surrounding rock over roughly a billion years ago and was preserved close enough to the surface to be economically mineable. Rather than one uniform ore body, Ekati's operators have worked through a sequence of individual pipes over the mine's operating life, bringing new pipes into production as others are depleted.
Extraction at Ekati has generally followed a pattern common to many large kimberlite mines: pipes are typically mined first as open pits, since near-surface ore can be accessed relatively efficiently with large-scale earth-moving equipment, and as a pit deepens and open-pit mining becomes less economical relative to the volume of waste rock that has to be moved to reach ore, some pipes transition to underground extraction methods to continue accessing ore below what an open pit can reasonably reach. This progression — from open-pit to underground as individual pipes mature — is a defining structural feature of how a multi-pipe kimberlite operation like Ekati is run over its lifetime, and it's part of why a mine like this can remain in production for decades even as any single pit eventually reaches its practical depth limit.
Ownership History: A Mine That Has Changed Hands
Ekati was originally developed by BHP, the global mining company (operating in this context as BHP Billiton), which built the mine and brought it into production in 1998 as part of what was, at the time, a notable diversification into diamond mining for a company primarily known for other commodities. Over the following years and decades, ownership and operation of Ekati has changed hands between mining companies, as is common for large, long-lived resource assets as corporate strategies shift and companies buy, sell, or restructure their mining portfolios.
Dominion Diamond Mines later became associated with owning and operating Ekati, and more recently Burgundy Diamond Mines has been connected with the operation. Rather than treating any single ownership snapshot as permanent, the more useful way to understand Ekati's ownership history is structurally: it is a mine that, like many large long-life mining assets, has moved between corporate owners over its operating life, while continuing to produce diamonds from the same underlying kimberlite pipes throughout those transitions. Buyers and researchers who want the current, precise ownership and operating status at any given moment should check current public records directly, since ownership of large mining assets can and does change.
Ekati's Significance in Canadian and Global Diamond History
It's difficult to overstate how significant Ekati's 1998 opening was for the global diamond trade. Before Ekati, Canada was not considered a diamond-producing country in any meaningful commercial sense. Within a decade of Ekati's opening, Canada had become one of the world's top diamond-producing nations by value, driven by Ekati and the mines that followed it, most notably Diavik. That rapid rise is what's often referred to informally in the trade as Canada's "diamond rush" — a compressed, high-stakes period of exploration, staking, and mine development that mirrored, in miniature, historic resource rushes in other commodities, except playing out over years rather than a single dramatic event.
Ekati's opening also had a broader effect on how the diamond trade thinks about country-of-origin and mine-of-origin as commercially meaningful concepts. Canadian diamonds, with Ekati as the original example, helped popularize the idea that a diamond's specific mine of origin could be tracked, documented, and marketed as a distinct value proposition — separate from the diamond's cut, color, clarity, and carat weight. That shift in how origin is discussed in the trade traces directly back to the credibility Ekati established as Canada's pioneering diamond mine.
Ekati Compared to Other Major Canadian Diamond Mines
Ekati is often discussed alongside Canada's other major diamond mines, particularly Diavik and Gahcho Kué, since all three sit in the same general region of the Northwest Territories and share a broadly similar subarctic operating context. The table below summarizes general, well-established distinctions between them at a high level — precise production figures and ownership details shift over time and are best verified against current sources rather than treated as fixed.
| Mine | Discovery / Opening Era | Region | General Structure |
|---|---|---|---|
| Ekati | Discovered early 1990s; opened 1998 — Canada's first diamond mine | Lac de Gras area, Northwest Territories | Multiple kimberlite pipes; open-pit extraction transitioning to underground as pits mature |
| Diavik | Discovered mid-1990s; opened early 2000s, shortly after Ekati | Lac de Gras area, Northwest Territories, near Ekati | Multiple kimberlite pipes; open-pit and underground extraction depending on the pipe |
| Gahcho Kué | Developed later, opening in the mid-2010s | Northwest Territories, southeast of the Ekati/Diavik cluster | Kimberlite pipe cluster mined primarily via open-pit methods |
What these three mines share is more notable than what separates them: all three are remote, subarctic, multi-pipe kimberlite operations that rely on similar seasonal logistics, and all three contributed to establishing Canada's reputation as a source of well-regulated, traceable natural diamond production. Ekati's distinction within that group is chiefly historical — it was first, and it's the mine whose discovery and opening effectively created the modern Canadian diamond mining industry that Diavik and Gahcho Kué later became part of.
Environmental and Community Considerations
Operating a large mine in a subarctic, ecologically sensitive environment like the Lac de Gras area comes with real environmental management obligations, and Ekati's operators have had to address concerns specific to that setting over the mine's operating life. These include managing waste rock and tailings in a permafrost environment where standard temperate-climate containment approaches don't directly apply, monitoring impacts on regional caribou herds that migrate through the broader area and are culturally and economically significant to Indigenous communities in the Northwest Territories, and managing water use and discharge given the sensitivity of Arctic and subarctic freshwater ecosystems.
Ekati's development and ongoing operation has also involved agreements and consultation with Indigenous communities and governments in the region, reflecting the broader shift in Canadian resource development toward formalized Indigenous engagement, impact-benefit agreements, and employment and business opportunities for local and Indigenous communities connected to mining projects in their traditional territories. Canada's diamond mining sector overall — and Ekati specifically, as the mine that established the template — is generally regarded in the trade as operating under comparatively strict environmental and regulatory oversight relative to some other diamond-producing regions globally, which is part of what underpins the traceability and provenance story Canadian-origin diamonds are often marketed around.
Ekati-Origin Diamonds and Mine-of-Origin Certification
One of the more commercially significant outcomes of Ekati's existence is the way it helped establish mine-of-origin certification as a real, documentable feature of a natural diamond, rather than an abstract marketing claim. Some Canadian diamonds, including stones traceable to Ekati specifically, are marketed with certification and laser-inscription programs that document a stone's mine of origin and track it through cutting and polishing, giving buyers a documented chain of custody back to a specific mine rather than a general country-of-origin claim.
For a trade buyer, this matters because it addresses a real gap in how most natural diamonds move through the global supply chain: the overwhelming majority of rough diamonds are sorted, mixed, and processed through international channels without preserving mine-specific origin data all the way to the finished, polished stone. A diamond marketed and documented as Ekati-origin, or more broadly as Canadian-origin with mine-level traceability, is meeting a specific and genuinely differentiated demand from buyers and end consumers who want documented, verifiable origin rather than a general assurance. That's a meaningfully different value proposition than country-of-origin marketing alone, and it's part of why "Ekati diamond" and "Canadian diamond" carry real recognition in trade and consumer conversations even among buyers who couldn't necessarily describe the mine's geology or ownership history.
Natural Mine-of-Origin Diamonds vs. Lab-Grown: Tradeoffs Worth Understanding
Ekati's story is a useful lens for thinking honestly about the tradeoffs between natural, mine-of-origin diamonds and lab-grown CVD diamonds, since Ekati represents one of the more well-documented, traceable ends of the natural diamond spectrum. A natural diamond traceable to a specific mine like Ekati carries geological history — formed deep in the earth over roughly a billion years and brought to the surface by ancient volcanic activity — plus, when properly certified, a documented chain of custody that some buyers and end consumers find genuinely meaningful, separate from the stone's visible 4Cs grade.
A lab-grown CVD diamond, by contrast, is chemically and optically a real diamond, graded on the same 4Cs scale by the same major labs, but it's produced in a controlled reactor environment over a period of weeks rather than mined from a specific geological deposit, and its supply scales with manufacturing capacity rather than being constrained by a finite ore body like Ekati's kimberlite pipes. Neither option is objectively "better" — a well-cut, well-graded stone from either origin can look identical to the naked eye and hold the same grading credentials. The distinction buyers weigh is origin, story, supply dynamics, and price per carat, and different customers reasonably prioritize different things: some specifically want the geological rarity and documented mine-of-origin story a stone like an Ekati diamond can offer, while others prioritize the value and consistent availability lab-grown CVD diamonds provide. A jeweler who understands both sides of that tradeoff, rather than treating one as automatically superior, is better positioned to have an informed conversation with either kind of customer.
Sourcing Natural and Lab-Grown Diamonds From One Wholesale Supplier
For a jeweler or designer who wants to offer customers both sides of that conversation — genuine natural diamonds with documented origin appeal, and CVD lab-grown alternatives — sourcing both from a single relationship rather than managing separate vendors is a real operational advantage. Guru Diam carries genuine natural diamonds as a distinct catalog alongside its CVD lab-grown line, kept clearly separated rather than blended, so a natural stone is always represented as natural and a lab-grown stone is always represented as lab-grown, with no ambiguity between the two on any given product.
Guru Diam is a trade-only wholesale supplier — buyers are independent jewelers, designers, and manufacturers, not end consumers — carrying standard, antique, and exotic diamond shapes across both natural and CVD lab-grown catalogs, along with certified loose stones and finished jewelry, with IGI, GIA, and GCAL certification all available. That breadth means a jeweler fielding a customer question about Canadian or mine-of-origin diamonds, and a separate customer looking for a value-driven CVD lab-grown alternative, can be served from the same sourcing relationship rather than two. In-stock inventory ships same-day from Guru Diam's New York location before 6pm EST and its Los Angeles location before 4pm PST, and diamonds are cut, set, and polished in-house before final grading and shipment — one supplier, one shipment, one relationship, for both the natural and lab-grown side of a jeweler's counter.
Jewelers can browse certified natural and lab-grown loose diamond inventory through the certified diamonds category, source matched pairs through matching pairs, and review fancy color options through fancy color loose diamonds. Trade accounts can review wholesale terms at the wholesale hub or apply directly through trade partner, and a jeweler building a full piece around a natural or lab-grown center stone can work through custom jewelry, with rings finished in 4-6 days.
What Ekati's Future Looks Like
Like any large mining operation built around a finite set of kimberlite pipes, Ekati's long-term future depends on the productive life remaining in its known ore bodies, continued exploration for additional pipes within its broader claim area, and the economics of transitioning more of its production from open-pit to underground extraction as existing pits mature. Mines of Ekati's scale and history don't typically close abruptly — production volumes generally decline gradually as the most accessible ore is depleted, with operators evaluating whether remaining underground resources justify continued investment as conditions change.
Beyond its own operating horizon, Ekati's legacy as the mine that started Canadian diamond mining is already secure regardless of how much longer it remains in production. It proved the geological thesis that brought Fipke and Blusson to Lac de Gras in the first place, it established the logistical and regulatory playbook that every subsequent Canadian diamond mine has built on, and it helped create mine-of-origin traceability as a real, marketable feature of natural diamonds rather than an abstract idea — a legacy that will continue shaping how Canadian-origin diamonds are discussed and sourced in the trade long after any individual pit at Ekati itself reaches the end of its productive life.
Frequently Asked Questions
What is the Ekati diamond mine?
The Ekati diamond mine is a diamond mining operation near Lac de Gras in Canada's Northwest Territories that opened in 1998 as Canada's first diamond mine. It's built around multiple kimberlite pipes and is credited with launching Canada's commercial diamond mining industry.
Who discovered the Ekati diamond mine?
Geologists Chuck Fipke and Stewart Blusson discovered the diamond-bearing kimberlite at Lac de Gras in the early 1990s, following years of tracing kimberlite indicator minerals across the Northwest Territories. Their discovery led directly to Ekati's development and 1998 opening.
Where exactly is the Ekati mine located?
Ekati is located roughly 300 kilometers northeast of Yellowknife in Canada's Northwest Territories, in a remote subarctic area near Lac de Gras. The site is accessed primarily by aircraft, with seasonal ice roads open for a limited window each winter for heavy freight.
Who owns the Ekati diamond mine now?
Ekati was originally developed by BHP and has changed hands between mining companies over the years, including Dominion Diamond Mines and, more recently, Burgundy Diamond Mines. As with any large mining asset, ownership can shift, so buyers wanting the current precise ownership status should check current public records.
Is Ekati an open-pit or underground mine?
Ekati is a multi-pipe kimberlite operation that has generally used open-pit mining for its individual pipes at first, transitioning some pipes to underground extraction as pits deepen and open-pit mining becomes less efficient. Different pipes across the site can be at different stages of this progression at the same time.
What makes an Ekati or Canadian diamond different from other natural diamonds?
Ekati helped popularize mine-of-origin certification and laser inscription for natural diamonds, giving some Canadian diamonds a documented chain of custody back to a specific mine rather than just a general country-of-origin claim. That level of traceability is a genuine point of differentiation buyers who care about documented origin often look for.
