About 15-20 years ago, there was a "Modern Marvels" on History that touched on this mine and how it was a different way they mined (comparative to the DeBeers mines in SA) based on the geologic structures they found bearing diamonds.
They then covered similar geography in Canada, where BHP Billiton had already started building the deep underground structures to support the mining operation.
Jacob Rothschild is the majority shareholder in BHP.
The full, original episode can't be found anymore, only a 30-minute edited and compressed version. And I haven't heard of large quantities of high quality Canadian stones in the market, so why keep massive underground diamond mines that don't produce diamonds in operation, 15 years later?
