    Sixteen holes for 5,040 metres through the Hearne Northwest Extension, spotted in a pit bench face in late 2021, showed ten significant kimberlite intersections - up to 86 metres in hole MPV-22-568C - and modelling suggests a volume potentially equal to the Hearne orebody as originally defined. It sits below the exposed benches and plunges north-west, so the joint venture is looking at whether it can be mined underground.

    Finished the 2022 Kennady North program with 25 of 35 holes hitting kimberlite over more than 5,000 metres, and a new body, KE, about 450 metres east of the Kelvin deposit - three holes through kimberlite sheets up to 2.13 metres, thin so far and to be drilled again in 2023. Eight volcaniclastic intersections came from the North Anomaly, and the ground now runs to over 113,000 hectares.

    Halfway through a 6,000 metre winter program on Kennady North, 16 of 20 holes had hit kimberlite across three of four target areas - all seven holes north of Faraday 1-3, all five south of Faraday 2 at an average 4.5 metres wide, and four of six south of Kelvin. The North Anomaly holes included volcaniclastic kimberlite, which the company notes often points to a larger body.

    Closed the US$50 million junior secured loan from Desmond and issued him warrants over 41,000,000 shares at US$0.60975, exercisable to December 2027. The loan ranks behind the second lien notes, can be prepaid without penalty, and is a related-party transaction under Canadian minority-protection rules; the warrants were partial consideration for the credit rather than a separate raise.

    The updated technical report put Mountain Province's 49% share of the mine at a C$1,233 million pre-tax and C$964 million post-tax present value at a 7.5% discount. Reserves stood at 42.6 million carats at 1.51 carats per tonne, with 2.6 million carats added before depletion, and the Tuzo reserve grade rose 11% to 1.33 carats per tonne. Outside reserves sit 3.0 million indicated carats at 1.25 and 20.3 million inferred at 1.72 carats per tonne, and the mine plan moved to 3.6 million tonnes a year.

It also started a 6,000 metre drilling and geophysics program on the wholly-owned Kennady North ground aimed at new discoveries.

    Set out the terms of a proposed US$50 million loan from Dermot Desmond ranking behind the existing second lien notes: 8% to December 2022, then 2% above whatever replaces the notes, maturing December 2027, with 41 million warrants at C$0.78 attached. Nothing was binding yet - it needed definitive documents, regulatory clearance and a vote of disinterested shareholders. The company also said the undrawn US$25 million first lien revolver would be used within weeks to fund the winter ice-road resupply, and that it expected US$50 million of extra cash flow by end-2022 to help a wider debt restructuring.

    Repaid the Dunebridge term loan in full with a final US$11.5 million payment, three months early, and extended the US$25 million revolving facility from the same lender to 31 March 2022 on unchanged terms for a fee of 2% of drawn principal. The board again recorded the finding that the company was in serious financial difficulty, the wording that lets a related-party deal skip a formal valuation - Dunebridge is ultimately owned by largest shareholder Dermot Desmond.

    Borrowed a further US$33 million from Dunebridge at a fixed 10% a year plus a 5% fee on each drawing, on top of the existing US$25 million revolving facility, with the term loan shrinking to US$22 million in July and due at the end of December 2021. Two directors connected to the major shareholder recused themselves, and the board recorded a formal finding that the company was in serious financial difficulty - the plainest statement of distress in the record so far.

    With Antwerp shut and no traditional buyers, agreed to sell US$50 million of run-of-mine diamonds (stones under 10.8 carats) to Dunebridge Worldwide at prevailing market prices, the first tranche about US$22 million. Dunebridge takes a 10% fee a year on each sale plus costs, and any surplus when it eventually resells is split equally. A committee of four directors independent of both management and the major shareholder reviewed it against the alternatives - a structure that signals a related-party transaction.

    Scotiabank and Nedbank relaxed the covenants on the undrawn US$50 million revolving facility for three quarters of 2020, lifting the maximum leverage ratio from 4.0 times to 4.5 at March, 5.0 at June and 4.25 at September; if June leverage exceeded 4.5 times, half the facility would become unavailable. This is covenant relief granted as Covid-19 closed the diamond market, not a tightening, and the facility remained undrawn.

    Wrote $115.8 million off the carrying value of the mine because expected future diamond prices had been cut to match the market, turning the fourth quarter into a $115.7 million loss, and withdrew all guidance over Covid-19. The mine itself performed: 3.58 million tonnes treated in 2019 for 6.82 million carats at 1.90 carats per tonne, with fourth-quarter grade at 2.11, but realised prices fell to US$64 a carat and cash costs ran at $103 a tonne treated and $49 a carat recovered.

    Chose to leave Nasdaq rather than fix a share price that had sat below the US$1 minimum for more than 30 trading days, saying almost all volume was on the Toronto exchange and the cost of the second listing was no longer worth it. Last Nasdaq trading was around 10 February 2020; the shares kept trading in Toronto and the company said it would eventually seek to deregister from the SEC entirely.

Holes cut up to 119 metres of kimberlite, it comes to surface under lake sediment, and a 115.2 kilogram sample yielded a 0.28 carat diamond.

The bigger change was value: US$140 a carat against US$112, on revised stone size distribution modelling - well above the roughly US$60 to US$85 a carat Gahcho Kué itself was fetching at tender.

The mine treated 1.68 million tonnes in the half for 3.57 million carats on a 100% basis, a recovered grade of 2.12 carats per tonne, ahead of plan. A $6.3 million quarterly net loss came mostly from a $7.7 million unrealised currency loss on the US dollar notes.

Kennady shareholders' equity was rolled into Mountain Province stock rather than cashed out.

    The second sale of 2018 fetched US$142 a carat, by far the highest Mountain Province had achieved at any tender, though on only 177,000 carats for US$25.1 million; on a normalised basis the price was US$76, so the headline reflects an unusually large-stone assortment rather than a market move. The release also confirmed the company's intention to begin paying a dividend.

It brings in the Kelvin kimberlite at 13.62 million carats indicated, 1.60 carats per tonne, valued at US$63 a carat on a 2016 bulk sample, the Faraday cluster at 5.02 million carats inferred, 1.54 carats per tonne and US$98 a carat, and 67,164 hectares surrounding the mine.

Surveys also flagged a new gravity target between the Tesla and Tuzo pipes and a possible south-west extension of Tesla; 11 more holes were still to drill.

    Closed the US$330 million 8.0% second lien notes, repaying and terminating the project loan and clearing the De Beers development-cost balance. Interim CEO David Whittle said this removed the project loan's cash reserve accounts, lender-approval restrictions and, in his words, any further need for bank waivers - the first mention in the record that the company had been seeking waivers under that facility. Patrick Evans, chief executive through the whole build, was no longer in the role.

The notes would rank behind a new US$50 million first lien revolving facility to be signed at the same time, and no interest rate had been set.

    The seventh diamond sale was the largest to date by both value and volume, 463,000 carats for US$27.1 million, but at US$59 a carat against US$72 to US$95 in earlier 2017 sales; the fall was because 85,000 carats of small goods were fast-tracked into it and De Beers won most of the large and coloured stones on offer. On a like-for-like basis the company put the price at US$72 a carat, in line with US$75 year to date. The mine was running well above its 1.57 carats per tonne reserve grade, recovering 2.05 carats per tonne from 1.84 million tonnes in 2017 to the end of August for 3.77 million carats on a 100% basis.
