What Diamcor Mining does
Diamcor Mining Inc. is a publicly traded Canadian junior diamond mining company (TSX-V:DMI, OTCQB:DMIFF) incorporated in 1985 and headquartered in Kelowna, British Columbia. The company's sole operating asset is the Krone-Endora at Venetia Project in South Africa's Limpopo Province, acquired from De Beers Consolidated Mines in February 2011. The project covers 5,888 hectares directly adjacent to De Beers' flagship Venetia Diamond Mine, with granted mining rights covering 657.71 hectares and an NI 43-101 inferred resource of 1.4 million carats with a high proportion of gem and near-gem quality diamonds. The deposit sits in only 15 meters of diamondiferous gravel between surface and bedrock, enabling low-cost strip mining.
Diamcor generates revenue from trial mining operations through the sale of rough diamonds, historically through a strategic alliance with Tiffany & Co. Canada (which held first right of refusal on up to 100% of production until the off-take agreement was terminated in February 2026), through international tenders conducted at Koin International's Dubai facilities, and through sales of run-of-mine goods to the South African State Diamond Trader. Processing relies on conventional mineral processing equipment including dense medium separation, log-washers, and electronic x-ray diamond recovery systems. Phase 1 upgrades completed in September 2021 were designed to double processing volumes, with Phase 2 expansion plans announced in March 2022.
The company is led by CEO Dean H. Taylor and COO Dr. Kurt Petersen, with 11-50 employees. Diamcor is sub-scale, with annual revenue of approximately $830,000 in 2024, and has historically funded operations through a series of debt and convertible financings rather than operating cash flow. The company faces material financial distress signals, including a June 2025 Section 244 notice from Tiffany & Co. under the Bankruptcy and Insolvency Act, a July 2025 application for a Management Cease Trade Order, and an extension of its 2025 AGM to June 30, 2026.

Diamcor Mining competitors and assessment
Company assessmentBroad incumbents
- De Beers Group: The world's largest diamond mining group and Diamcor's immediate geographic neighbor via the flagship Venetia Mine adjacent to the Krone-Endora project. Operates globally across exploration, mining, sorting, and marketing of rough diamonds, making it the dominant incumbent in the same geological setting.
- Alrosa: Russian state-controlled diamond mining giant producing the majority of the world's rough diamonds by volume. Operates broadly across the rough diamond value chain from mining to cutting, providing the global benchmark for rough diamond pricing relevant to Diamcor's tenders.
- Anglo American plc: Diversified mining major (LSE:AAL) that previously held De Beers and now retains an 85% economic interest. Comparable as a broad incumbent with material diamond mining exposure through De Beers, influencing global rough diamond supply and pricing dynamics relevant to Diamcor.
Direct peers
- Lucara Diamond Corp: Canadian-listed junior diamond miner (TSX:LUC) operating the Karowe Mine in Botswana, producing high-value gem-quality rough diamonds for global markets. Comparable as a publicly traded single-asset diamond producer focused on large, high-quality stones sold through tender.
- Mountain Province Diamonds: Canadian-listed junior diamond miner (TSX:MPVD) and joint venture partner with De Beers at the Gahcho Kué Mine in Canada. Closely comparable to Diamcor as a publicly traded diamond producer with a De Beers counterparty relationship and rough diamond sales via tender.
- Petra Diamonds: Mid-tier diamond producer (LSE:PDL) operating the Cullinan, Finsch, and Kimberley Underground mines in South Africa. Comparable as a publicly listed diamond miner with multi-asset South African operations producing gem and near-gem rough diamonds.
- Gem Diamonds: LSE-listed diamond miner operating the Letšeng mine in Lesotho, renowned for producing large, high-value rough diamonds sold through tender in Antwerp and Dubai. Comparable as a publicly listed single/joint-asset producer targeting the high-value rough segment.
- Stornoway Diamonds: Canadian diamond producer (formerly TSX:SWY) that operated the Renard Mine in Quebec. Comparable as a publicly traded single-asset diamond miner that has faced financing and operational restructuring challenges, similar in profile to Diamcor's small-cap, single-project risk profile.
- Firestone Diamonds: Diamond mining and development company previously operating the Liqhobong Mine in Lesotho. Comparable as a publicly listed junior diamond producer with single-asset exposure and tender-based rough diamond sales.
Emerging players
- Tsodilo Resources: Canadian-listed junior exploration company (TSXV:TSD) focused on diamond and base-metal projects in Botswana. Comparable as a small-cap, publicly traded diamond-focused junior with exploration-stage assets and limited near-term production.
