Good morning, ladies and gentlemen, and welcome to the Mountain Province Diamonds Inc. Q4 and Full Year 2022 Conference Call and Webcast. At this time, all lines are in a listen-only mode. Following the presentation, we will conduct a question-and-answer session. [Operator Instructions]. This call is being recorded on Thursday, March 23, 2023.
I would like to turn the conference over to Mark Wall, President and CEO. Please go ahead.
Mark Wall
Thank you very much. Good day to everyone who's dialed in to listen to our Q4 and full year 2022 results call. My name is Mark Wall, and I'm the President and CEO of the company. Also present on this call is Steven Thomas, our CFO; Reid Mackie, our Vice President and Head of Sales and Marketing; Matt MacPhail, our Chief Technical Officer; Dr. April Hayward, our Chief Sustainability Officer; and Dr. Tom McCandless, our Vice President and Head of Exploration. The team will be available for any questions you may have at the end of this call.
Firstly, I would like to draw your attention to our cautionary and forward-looking statement. This presentation will be posted on our Web site for anyone who needs additional time to review this statement. Mountain Province is a Canadian diamond producer mining Canadian diamonds to the high standards of corporate social responsibility, and that's something that we continue to be proud of.
We own 49% of the Gahcho Kué mine in the Northwest Territories with De Beers owning the remaining 51%. We operate with a joint venture agreement with a four-person management committee, two from De Beers and two from Mountain Province. We've appointed De Beers as the operator of the asset and that has resulted in the operating systems of De Beers and Anglo American being applied to the assets, including the high standards of corporate social responsibility that I have already mentioned.
In addition to the 5,216 hectares of joint venture ground containing the existing mining operations, Mountain Province is the 100% owner of more than 113,000 hectares of highly prospective ground that surrounds the Gahcho Kué assets that we refer to as the Kennedy North project.
Today, I'll speak to 2022 full year and 2022 Q4 results and how Mountain Province Diamonds has changed over the last 12 months. I'll speak to our focus areas to 2023 and give a high level outlook for 2024. Matt, our CTO, will provide an update on the work that we’re doing around growth and the preliminary results so far. Steve, our CFO, will discuss the financial performance of the company. And Reid, our Head of Sales and Marketing, will provide an update on the diamond market. And I will then close out the presentation.
While there are many positives from 2022 that I will get into in a moment, the safety performance of the mine did not meet my expectations, including a tragic fatal accident during quarter three. Anglo American and De Beers have undertaken an exhaustive investigation to avoid a similar incident with regards to this type of heavy mining equipment anywhere else in the world. And the site management team are laser focused on ensuring a safe workplace in 2023. The safety of all workers, be they employees or subcontractors, must be our priority.
Before we turn to our 2022 results, it is helpful to review the situation at the end of 2021 when we had US$300 million in bonds terming in December 2022, with no refinancing in place and concern among some shareholders that this would be a highly diluted event. We had a debt to EBITDA ratio of around 2.8 to 1. We have a 2024 mine plan that was around 3.2 million carats as reported in our 43-101 Technical Report.
We had approximately $270 million in write-downs sitting on our balance sheet. We had no material organic growth prospects on the joint venture land. We had a 2019 43-101 Technical Report in place valuing our share of the joint venture at C$595 million pre-tax, pre-royalties. As we review the situation a year later, we have refinanced our bonds at a 9% coupon with zero dilution to shareholders. This attractive refinance was once again supported by our major shareholder, Mr. Dermot Desmond amongst others.
We also repaid US$60 million in debt during 2022 from operating cash flow. We moved our trailing debt to EBITDA from around 2.8 to 1 to around 1.8 to 1 at the beginning of 2023. We made a significant discovery beside and connected to the Hearne open pit that is potentially a catalyst to transition Gahcho Kué to an underground producer with additional drilling underway. If indeed a transition to underground mining proves to be feasible, and we are studying that potential right now, this would lead to a significant mine life extension. We are also studying any potential opportunities to bring the Kelvin and Faraday deposits into any future plan.
We completed the work to write back $240 million on the year end 2021 balance sheet driven by the improved company and market outlook. During 2022, we updated and issued our 43-101 Technical Report on the Gahcho Kué mine showing a pre-tax, pre-royalty NPV of $1.23 billion, an improvement of $638 million on the previous study, leading to an after tax NPV of C$964 million on our share of the Gahcho Kué asset only. The 2024 mine plan has been revamped from that published in our latest 43-101, with the planned current production increased to 2024 to be a planned year of positive cash flow and additional debt reduction.
The 2022 production plan was under significant pressure, with a tenfold increase in site COVID-19 cases in 2022 compared to 2021. The recovery plan developed led the mine to produce 5.52 million carats for the year with a strong Q4. In a challenging year for inflation and costs, we contained our costs despite the additional expenditure on COVID-19-related matters, inflation across the spectrum and very high diesel prices to finish the year at the bottom of original guidance for cost per tonne treated and $1 above original guidance for cost per carat produced, all of that coming together to deliver a record annual adjusted EBITDA at $177.2 million. I would sum up 2022 as a year with many difficulties and challenges, and also one with many achievements, as I believe we left 2022 much stronger than we entered into it.
Onto quarter four and full year results. A quick review of the full year 2022 highlights. As I've already stated, an adjusted EBITDA of $177.2 million, revenue of almost $399 million, the highest revenue in the company's history, and average value per carat of US$112, and the successful refinancing transaction as already stated with no dilution to existing shareholders. Despite the challenges in 2022, we saw production results in Q4 reflective of what the mine is capable of.
With production of 1.62 million carats, the fourth quarter represented a 12% increase in carat production relative to Q3, and a 29% increase relative to Q2 of 2022. We remain intensive to managing the inflationary cost pressures seen across North America, while at the same time balancing the operational and human resources demands required to run a remote mining operation with a skilled workforce.
As with any mining operation with such a high ratio of fixed costs relative to the variable, the main driver of value will always tend to fall on how many times can be processed, especially in our case where we currently have a large stockpile ahead of the plant. This effectively means that plant utilization must be maximized, which is a key metric we will continue to focus on. Matt will go into more detail on the operational aspects of quarter four in the next few minutes.
Focusing for a moment on the sustainable development efforts for 2022, the team continues to work hard to further its community involvement. The National Mining Association of Canada award for the Ni Hadi Xa joint environmental monitoring program was certainly a highlight for me. The award of 12 scholarships by Gahcho Kué mine to the top Northwest Territories graduates from Aurora College's early learning and childcare program was another highlight. These scholarships fill an important funding gap for part-time students living in the Northwest Territories who are ineligible for government funding because of their part-time status.
Another program that I believe is especially powerful is the recently launched Baby Bundle Program. In this program, the Gahcho Kué mine has partnered with the government of the Northwest Territories to tackle the issue of infant mortality in the Northwest Territories. It was determined that many cases of infant mortality were preventable, and this led to the development of this program where around 600 baby bundles will be delivered to every mother of an infant born in the Northwest Territories for the next three years. 400 of these bundles have already been distributed. The makeup of these bundles has been determined by the health ministry and includes essential supplies, information and resources to help new mothers and new families during the important early phase of a child's life.
Now moving to 2023 and the year ahead, our strategy remains consistent. Firstly, we will continue to focus on safety, sustainability and operational performance at the mine level. Secondly, we'll focus on organic growth at Gahcho Kué and Kennady, both on the underground potential, reviewing options to include the 13.6 million indicated carats and 7.4 million inferred carats from the Kelvin and Faraday deposits into possible mine plans as well as the targeted exploration programs.
Thirdly, we will continue to improve our balance sheet by working on reducing debt directionally towards a 1 to 1 debt to EBITDA ratio. As we focus on continuing to repay debt towards our target, we will review all opportunities to minimize debt costs and maximize capital allocation options. And fourth, we will continue to optimize our sales pipeline and look for ways to manage our costs while benefiting from our current nimble sales platform.
Earlier I raised our 2024 mine plan. While it's not necessary to review and update our entire 43-101 Technical Report, it is appropriate to provide a general outlook on production for 2024, which due to a widening of the ore body and other changes is now estimated to be 4 million to 4.4 million carats, up from the 3.276 million carats as published in the current 43-101 Technical Report. While some additional carats have come into the plan over the life of the mine, the overall plan from 2025 onwards is materially the same. We will continue to review the 2024 plan as a part of the normal strategic business planning process during this year to seek further optimization and improvement.
We are now into 2023. We know that quarter one for Gahcho Kué is a very busy time. With almost 400 kilometers of ice road having been constructed and the move into the mine of most of the ores and equipment for the year taking place, that work is on schedule and going well. At the same time, mining and processing operations take place through the coldest temperatures and the most challenging conditions of the year, with temperatures in the range of minus 50 degrees not uncommon. While Q1 is always a challenge, it sets the operation up to deliver results through the full year.
I will now hand over to our CTO, Matt MacPhail, to provide additional details on our operating results.
Matt MacPhail
Thanks, Mark. I'm now going to walk through Q4's operating performance with some reference to full year 2022 results as well. During the fourth quarter, 10.145 million tonnes were mined, total tonnes ore plus waist, which includes 706,000 ore tonnes. That compares to 10.813 total tonnes mined and 1.02 million tonnes of ore that were mined in Q4 of 2021.
Ore processing in 2022 Q4 the process plant, we processed 828,000 tonnes of Kimberlite at an average grade of 1.96 carats per tonne, which resulted in 794,000 carats recovered attributable to Mountain Province. This processing result compares to Q4 of 2021, the year prior where we processed 813,000 tonnes at a grade of 1.86 where we recovered 741,000 carats attributable to Mountain Province and 1.511 at 100%.
For the entire 2022 operating year, we mined almost 34 million total tonnes, including 4.1 million tonnes of ore. Also in 2022, 3.1 million tonnes processed at an average gain of 1.78 across the year for total attributable carat production of 2.7 million carats, or 5.52 on 100% basis. The year prior to that in '21, we processed just shy of 3.1 million tonnes of ore at a grade of 2.02 slightly higher grade which resulted in just over 3 million carats recovered attributable to us and 6.229 at 100%.
So to summarize 2022’s performance, we processed almost the same quantity of ore tonnes as in 2021, albeit at a slightly lower grade, resulting in fewer carats recovered. To start off 2023, we're well positioned with stockpile at year end 2022 of over 1.7 million tonnes containing over 2.7 million carats. We'll build on this stockpile in 2023 as the ore mining outpaces the plant's throughput rate. This was set up well for 2024 where we enter a period of high waste stripping that we mine down through the top section of the Tuzo ore body.
Now moving on to the Hearne Northwest extension and our organic growth opportunities at the mine, I wanted to touch on some of the exciting things we're working on to unlock value at Gahcho Kué. As you may recall, in 2022, we discovered what we now call the Hearne Northwest extension, a previously unknown occurrence of Kimberlite part of the Hearne ore body. And last year, the JV drilled this extension to better understand its extents. And now in 2023, we are continuing to drill this drill campaign at Hearne.
The newest round of drilling at Hearn is focused on testing the extents of the ore body at depth as well as generally increasing our understanding of the ore body below the current pit. Additionally, this year's program has meters allocated to the NEX and Tuzo ore bodies with a similar goal of better understanding these ore bodies below the current pit limits.
All this resource information is feeding into our internal study, which is looking at the potential of Gahcho Kué to transition to underground mining. Early indications are positive, but there remains much work to be done. We expect to be able to share more information with the market regarding the progress of these initiatives in the later stages of 2023.
Now I'm going to hand it back over to Steve, our CFO, who's going to run through the financial results of the company for Q4 and 2022.
Steven Thomas
Thank you, Matt, and good morning, everyone. 12 months ago, having just joined the company, I said that I was looking forward to being able to talk to our future financial progress for the company, building on the strong performance in 2021. I'm pleased to say that I can do that this morning given the financial results for 2022.
Before discussing specific aspects of the financial results and certain material transactions flowing into the 2022 financial statements, I will first provide a high level financial overview of the business. Although the year saw some operational changes impacting diamond recovery, the benefit of cost control and strong diamond price underpinned record financial results in respect of turnover and earnings from operations.
When normalizing 2021 for the exceptional impact of the impairment reversal, records were also set for operating income, net income, earnings per share, and adjusted EBITDA. The balance sheet was strengthened considerably with the company refinancing via long-term debt on competitive commercial terms and without any dilution to equity. The successful refinancing was achieved with a renewed commitment from our key lenders, and in particular our major shareholder, Mr. Desmond.
It is worth noting also that with the refinancing achieved, the going concern now which has been in the financial statements since Q2 2020, initially due to concerns about COVID impacts, but more recently reflecting the pending refinancing challenge, has now been removed from these statements, with both concerns effectively managed.
Lastly, for the 2022 financial statements, the audit report from KPMG is bifurcated in respect of the current year 2022 numbers and 2021 comparatives, as we voluntarily deregistered to terminate SEC reporting obligations per our intention announced in 2020. We expect this simplification to deliver corporate cost efficiencies going forward.
Now turning to the balance sheet, the year-end total long-term debt of US$245 million comprises US$195 million of 9% senior secured notes due 2025 and the US$50 million junior secured credit facility due 2027. During the year, we paid down US$110 million against the expiring senior secured notes using $60 million from operational cash flows while drawing down the junior credit facility.
In Q4 2022, accounting for changes in the above debt instruments has had material impacts in the financial statements, and I will highlight those shortly. Not surprisingly, the working capital position of the company has changed significantly to a positive balance of $129 million for 2022 compared to negative $276 million of 2021 year end, a negative $182 million at the start of the quarter. This is due to the debt reclassification in 2022 now as a long-term debt. Absent that impact, the comparable working capital number would be $100 million for 2021 compared to this year's $129 million.
Looking at current assets, the value of inventory of $161 million, although consistent with the balance at the start of the quarter, has changed materially from $110 million at the end of 2021. This increase of $51 million is largely explained by a $12 million increase in supplies, reflecting the higher volume and carrying cost of fuel held in stock, which was purchased in Q1 2022 where the prices spiked due to the invasion of Ukraine. So this year, I can confirm that nearly all fuel has been delivered on the winter road at prices in line or below budget.
Secondly, the significant increase in the value of the ore stockpile by $26 million, doubling its value compared to year end 2021 reflects the planned growth in the volume of the ore stockpile by 1 million tonnes over the course of the year, which will source future processed ore. And then lastly, the value of rough diamonds which are passing through the sales pipeline has increased by $12 million reflecting a 9% increase in volume and 18% increase in cost per carat, much of which is attributable to non-cash depreciation accounted for in the stock.
Within current assets is a 2.2 million derivative asset, an increase of approximately 1.5 million compared to 2021. 3 million of the 2022 balance is the value assigned to the redemption features within the senior secured notes, which constitute an embedded derivative asset. This value is offset by the embedded derivative liability calculated on outstanding hedge currency products valued at $900,000.
Within current liabilities, the warrant liability reflects the fair value of the one right held under the related party junior credit facility established in Q1 2022. The change in valuation is primarily due to changes in the volatility and risk-free interest rate factors underpinning the calculation causing the liability to reduce in value from $15 million as reported in Q1 to $7.2 million now.
Within long-term liabilities is the Canadian dollar equivalent value of the US$195 million secured notes payable and the US$50 million junior credit facility translated at the prevailing year end rate of C$1.355 to the U.S. dollar. As mentioned earlier, uniquely in 2022 and specifically Q4, the impact of the increase in interest rate in the junior credit facility is booked entirely in that period and that results in a $10 million increase in the carrying value of the loan and the finance expense, which impacts net income. This non-cash impact booked now will have the effect of reducing interest charges going forward.
Secondly, to note for that facility, the changing terms to defer all interest in principal payments until after the secured loan notes are repaid resulted in a $5 million reduction in the carrying value of the debt and an equivalent deemed capital contribution as the loan is provided by a related party, Dunebridge Worldwide Ltd..
In respect of the secured notes payable, the carrying value of the loan is reduced by an amortized transaction costs of $7 million, which comprises the original issue discount of 3% equally in US$5 million plus capitalized transaction-related fees and that is offset by the $3 million embedded derivative asset mentioned earlier.
Other material liabilities on the balance sheet include the decommissioning and restoration liability, which has reduced by $12 million since the start of the year due to the significant increase in the risk-free interest rate in that calculation. The increase in the fourth quarter for the decommissioning liability by $3.4 million is in line with the increase in the undiscounted liability, which reflects the impact of increased inflation assumptions in those cash flows.
Lastly, the deferred tax liability, which is established in respect of future mining royalties payable, has increased by approximately $21 million over the year, reflecting the profitability of 2022 with taxable production income of $162 million, taxed at 13%, which has been deferred through the utilization of available tax pools.
Turning to our earnings. In 2022, the company sold approximately 2.7 million carats at an average price of US$112 per carat, or C$146 to generate $389 million in turnover. This compares to 2021 when approximately 3.2 million carats were sold at an average price of US$75 per carat, or C$94 for revenues of 298 million.
Q4 saw 758,000 carats sold at US$94 per carat compared to 809,000 carats at US$84 per carat in the comparative Q4 2021 period. Although price as expected has come off of the unprecedented peaks in H1, it remained at a very healthy level through the end of the year.
Production costs for the year were managed in line with plan and despite the general inflationary pressures, the material spike in fuel prices arising in Q1 2022 and the cost of reverting to a two-week in and out labor schedule and specific COVID-related prevention measures, the cash cost per tonne of ore treated, net of capitalized stripping at $89 per tonne remains as per 2021.
This resulted in earnings from operations for 2022 of $170 million compared to $114 million for 2021. And similarly, cash generated flows from operating activities for 2022 was $173 million versus $113 million in 2021, and that enabled the $60 million paydown U.S. of a low note mentioned earlier.
Before I move to discussing net income, it is worth noting that 2022's adjusted EBITDA was a record at $177 million versus $135 million for 2021. The resulting EBITDA margin based on sales is 46% in 2022 comparable to 44% for 2021. This non-GAAP measure is formulated to normalize for some of the flows which pass through the income statement to derive the net income number, which is 70.4 million in 2022, is materially different to the $297 million for 2021, and that was due to the $241 million impairment reversal in 2021. Absent that transaction, the comparable EBITDA number for 2021 will be approximately $56 million.
Looking at adjusted EBITDA for Q4 of $23.4 million compared to the full year of $177 million looks disproportionately low. The main driver for this is the impact of the $20.3 million non-cash realized FX loss arising in Q4 on the cancellation of the existing debt that hits that quarter compared to the full year equivalent impact of $23 million within the full year EBITDA of $177 million. If these respective realized losses were excluded from Q4 and the full year EBITDA, then Q4 would be approximately one quarter of the full year EBITDA amount.
Specifically in deriving net income for 2022 at $17.4 million, the net finance expense of 46.4 million compared to 14.4 million in 2021 includes several material adjustments equaling $14.2 million arising in respect of accounting for certain aspects of both loans, 10 million of which is in respect of the junior credit facility, which I mentioned earlier. Other income of 6.5 million is explained by the $6.2 million reduction in the fair market value of the liability for warrants, which I also discussed earlier.
Of the derivative loss of 2.5 million for 2022, 1.5 is in respect of currency contracts that settled during the year with the hedged rate below the prevailing spot rate. The equivalent derivative loss in 2021 was negligible. The company continues to use currency hedging to provide certainty in Canadian reported results for which all income is earned in U.S. dollars, but nearly all operating costs are incurred in Canadian dollars, other than for the payment of interest on the loans and some marketing-related costs. This policy will continue in 2023 with an intention to cover approximately half of all Canadian dollar costs through hedges.
The foreign exchange loss of $28 million for 2022 compared to a gain of $2.3 million for 2021 reflects the significant strengthening of the U.S. dollar over the year from an opening exchange rate of 1.26 to a closing rate of 1.35. The loss comprises a realized loss of $23 million in respect of the senior secured loan notes settled at rates that are different to those that were prevailing when the loan was taken out in December 2017.
The unrealized loss of 5 million is primarily in respect of the translation of the junior credit facility from the rate of 1.25 prevailing when the loan was taken out on March 28, 2022 compared to the year-end closing rate of 1.35. And it is notable that in Q4, there is a $5.6 million FX gain as the U.S. dollar actually weakened from the opening rate of 1.38 to the closing rate of 1.35.
Moving to net income after tax for 2022, there is a deferred tax of $21.2 million in respect of the mining royalty and that is similar in quantum to the deferred tax charge of $20.7 million arising in 2021. All of the above results and a net income of $49.2 million for 2022 compared to $276 million in 2021 which excluding the impairment reversal impact of 240 million would comparably be approximately $36 million.
2022 net income equals earnings per share of $0.23 on a basic and fully diluted basis and for Q4 with net income of 9.4 million, $0.04 per share on a basic and diluted basis. Specifically, net income for Q4 is lower than the average for the previous three quarters, given the comparatively lower selling price compared to the average for Q1 to Q3, but held by a proportionately higher volume of sales in Q4 at 29% of the full year sale. Additionally, the impact of the unique $10 million finance expense landing in that quarter, if adjusted, would result in Q4 being a relatively profitable period compared to previous quarters.
In conclusion, 2022, we're seeing the company stabilize its financial position with three and five-year term loans, which provides management with adequate runway to formulate the optimal capital structure going forward, helped by a delevered balance sheet. The company made significant inroads into reducing the debt and intends to do so in 2023 and return the capital to the lenders who have long supported the company.
This financial goal will be delivered as the company continues to generate the significant cash flow seen in 2022, which will be achieved through driving production to meet guidance and benefiting from our sales process that capitalizes on the positive market sentiment seen throughout 2022 which is continuing into 2023.
And that provides an appropriate segue to turn the presentation over to Reid Mackie, our VP Diamond Sales and Marketing. Reid?
Reid Mackie
Thank you, Steve. A few comments on the diamond market in 2022, which was certainly an eventful year for traders. It all started on an exuberant note with strong rough diamond price increases, low inventories and robust demand throughout the diamond pipeline. But Russia's invasion of Ukraine, rising inflation and ongoing COVID lockdowns in China brought uncertainty to the rough diamond market and rough diamond prices.
Demand for polished diamond softened and manufacturers began to accumulate higher inventories, particularly in the top end categories of polished. This was met with rough market price decreases during Q2 and Q3. As the year progressed, continued consumer spending in the U.S. kept the market steady.
Rough prices firmed later in Q3, and with reports of solid sales during the all important U.S. retail holiday period, positive price momentum was restored by year end. And this was helped by an easing of China's zero COVID policy which fueled hopes of a resurgent Chinese retail sector and boosted market sentiment at the end of the year and into 2023.
One key market development we saw during 2022 was that smalls brands and other lower price point diamond saw sustained price growth, which is visible here in the [indiscernible] price performance by size index. We continue to see that these categories of diamonds are experiencing strong demand alongside reduced supply as the market continues to adjust to the closure of Argo and the reduction in supply caused by sanction on Russian diamonds.
It's worth noting here that over 40% of the value of Gahcho Kué production profile comes from diamonds smaller than 1 carat, which positions Mountain Province well to benefit from this development. In Q4 2022, prices for larger, higher value rough diamond assortments also stabilized and though the outlook for 2023 is cautious for this category, the market is looking forward to positive movement here when China replenishes its stock at its recently reopened jewelry retail sector.
Lastly, we see overall that increasing consumer demand for ethically and sustainably sourced diamonds is driving the rollout of provenance and traceability platforms through the diamond pipeline down to retail. And we look forward to this evolution towards positive marketing based on diamonds origin as a development that will further support demand for our product in 2023 and well into the long term.
And with that, I'll hand it back over to Mark for his closing remarks.
Mark Wall
Thanks, Reid. As you've heard, 2022 was a transformational year for the company. To reiterate, our priorities as we move into 2023. Firstly, we'll continue to focus on safety, sustainability and operational performance at a mine level. Secondly, we'll focus on organic growth at Gahcho Kué and Kennady, both on the underground potential, reviewing options to include the 13.6 million indicated and 7.4 million inferred carats from Kelvin and Faraday into possible mine plants, as well as target an exploration program.
Thirdly, we continue to improve our balance sheet by working on reducing debt directionally towards a 1 to 1 debt to income ratio. As we focus on continuing to repay debt towards our target, we will review all opportunities to minimize debt costs and maximize capital allocation options. And fourth, we will continue to optimize our sales pipeline and look for ways to manage our costs while benefiting from our nimble sales platform that Reid has just described.
We entered 2023 with a robust diamond market with strength in the smaller gem quality goods that we are known for in a world where the production of natural diamonds has been in decline from 2017 levels. We continue to have the advantage of delivering Canadian diamonds into a market where purchasers care about diamond origin, even more so in the backdrop of the ongoing conflict in Ukraine. We have a growth pipeline to keep us focused on ways to extend the mine life, as we work with De Beers on delivering in here safe production.
My team is now available to take any questions that you may have.
Question-and-Answer Session
Operator
Thank you. Ladies and gentlemen, we will now begin the question-and-answer session. [Operator Instructions]. Your first question comes from the line of Daniel McConvey from Rossport Investments. Please go ahead.
Daniel McConvey
Yes. Hello, Mark, everyone. Thank you for a very good and thorough presentation. It's appreciated. A couple of questions. First one, just with the COVID issues you had in terms of productivity in terms of getting people, supply chain issues, et cetera, and maintenance I think suffered during COVID. Where are you now in terms of rectifying some of that? And do you have the skills and staffing levels that you need, or are you close to it now?
Mark Wall
Thanks. Good question. I think the issue with COVID, what's important to understand is that what happened in 2022 with the Omicron variant specifically is the regulations that we were operating under created by the government meant that all close contacts needed to go into quarantine. In a remote location, what that did in a situation where a lot of people who were even testing positive were not actually sick. But we were required to put a lot of people into quarantine. And we had circumstances where 30%, 40% of the entire workforce were quarantined at one time, which in a remote location where you can't move them because you're not allowed to, that is move them off site that you have to leave the folks quarantined for significant periods of time in their rooms was really quite devastating and difficult for the operation. So we worked closely with the government and the government was supportive. But as with all things in government, it took time to change those regulations so that there was a more equitable and reasonable quarantine requirement for COVID-19 cases on site. So while there is great medical facilities, great care facilities, this quarantine issue really caused us problems. Once the government changed those requirements and we were able to better manage the circumstances, remove people from site, change how things were working with quarantine, then things became quite a lot easier. I would say the overlay also with that was that we all know this. COVID was pretty tough on everyone, on all of us. It was especially tough if you imagine working in a remote mine site where you're wearing a mask all the time, you're away from your family for extended periods of time, because the rosters were increased, as Steve mentioned, for up to four weeks from two weeks. So it created a real degree of stress on the workforce. That is all now being returned and recovered. But we certainly did deal with a period where towards the end of COVID, a bunch of folks decided they just wanted to have a rest. So there were a lot of skilled people who were lost during that period. The sites now have the time to rebuild. That it's got -- the quarantine issues have gone, the regulations from the government that were causing us issues have gone, there is still a degree of testing and maintenance of quarantine issues, it hasn't completely gone away. The staffing of the site is now where we need it to be. We're actually looking at the moment towards slightly overstaffing, just to make sure that we bring the maintenance that you've correctly raised as a primary point of issue and concern back to exactly where it needs to be. So it's a long answer. But the headline is, there was many inputs that caused those issues. Those inputs have all now been managed. And we are rebuilt back to where we need to be.
Daniel McConvey
Okay. So it sounds like you're very -- based on what you were thinking six or nine months ago, you're very happy with where you are now?
Mark Wall
Yes.
Daniel McConvey
Okay, great. In terms of the new things you're looking at, the underground operations, et cetera, and Faraday, et cetera. Just where in a word, what is De Beers looking strongly at those options as well?
Mark Wall
We’re working together with De Beers on those options. What we have with De Beers and Anglo American is we have almost two seniors, if you like. We have De Beers that were a company in their own right and then we're absorbed into Anglo American as a larger company. So there are a number of hurdles to work through that are rational hurdles that a major company would have in order to look at it and investment decision. So the work is actually being done by the De Beers team. We are supporting that work. So it's De Beers themselves that are doing the work with our support in order to assess and analyze those opportunities from a financial and life of mine perspective, if that answers your question.
Daniel McConvey
Okay. Thank you. Last question, the start of 2023 from the winter road, et cetera, you're happy just in terms of the way the operations have started. We're well into the first quarter. Are you reasonably happy with production levels, et cetera so far?
Mark Wall
Well, we're talking about 2022, but I think at a high level I would say since my early introduction to the diamond industry, I'm never happy with quarter one. Quarter one is a quarter where it is so active with this ice road, with the weather conditions. I don't think there would ever be a quarter one that I would say that I'm happy with. Quarter one has proceeded safely. The ice road has gone well as active as that is. 44 million liters of diesel have moved along that ice road together with very large pieces of equipment, like replacement vibrating grizzly for jaw crushers, cone crushers, new rolls for a high pressure grinding roll, which is a very large piece of gear as well. So am I happy? I'm not happy with quarter one. I'm never going to be happy with quarter one because there was so much going on to set the mine up for the rest of the year that it's a very difficult quarter every year.
Daniel McConvey
Okay, all right. Thank you very much, Mark.
Operator
Thank you. And your next question comes from the line of Paul Zimnisky from PZDA. Please go ahead.
Paul Zimnisky
Hi, everyone. Thanks for doing the call. Maybe a follow up on the previous question looking at the life of mine beyond 2029, can you keep feeding the plan at capacity with just Hearn underground or do you think you will need ore from the Kennady assets as well? And I guess to phrase again, so beyond 2029, would it need to be a combination of Hearn underground and Kennady, or could it be more of an either/or situation?
Mark Wall
Hi, Paul. I think rather than steal Matt's thunder, I'll let Matt have a crack at that.
Matt MacPhail
Sure. Thanks, Paul, for the question. So again, still early days. We've done some high level mine planning scenario analysis to answer the exact questions that you are asking and we have some preliminary guiding answers to these types of questions. But findings are that in underground mining scenario at Gahcho Kué, under certain assumptions of mining method could essentially fill the plant about 80% of the way beyond 2030, even beyond the end of open pit reserves. So the plant would be 80% full via underground. Now that again leaves open the opportunity to top up the plant with external ore sources, those being the Kennady assets, which we own. So these are all influx and these are all opportunities in scenarios that we are continuing to assess and determine their economic and practicality viability of mining and how we get those into the mine frame. So long story short, underground, depending on some assumptions you make, probably won't fill the plant but we would like to look at the opportunity to integrate Kennady, and that's an ongoing discussion happening with us and our JV partners.
Mark Wall
Matt, perhaps I'll just add to that for Paul that specifically to the question around Hearne. Hearne as a high grade and potentially significant underground resource opens the opportunity for underground options at both NEX and Tuzo and 5034, as we move through the ore body. So the reason that we're so excited about Hearne is that it has the potential to unlock the optionality of underground at NEX, Tuzo as well as the Kelvin, Faraday deposits. And that's why you hear us keep talking about Hearne. We see it potentially as the key to the lock to unlock the potential both underground and for Kennady and Gahcho Kué.
Paul Zimnisky
Okay, understood and very clear and thank you very much.
Operator
Thank you. [Operator Instructions]. There are no further questions at this time. Please continue.
Matt MacPhail
Operator, I have some questions from the webcast that I'm going to read out and we'll have management answer them. So the first question comes from Jeff Stacey from Stacey Muirhead Capital Management. And the question reads, how do you envision your spending plans for 2023 will break down between continued debt repayment, further development of Kennady North and marketing initiatives?
Mark Wall
Steve, I know that you are waving in the whims [ph].
Steven Thomas
Thanks, Mark. Thank you for the questions, Stacey. I know it sounds a bit of a generic answer, optimized capital allocation, but given the importance of the growth story, the investment in the projects in conjunction with De Beers to keep that Hearne underground opportunity moving forward will be funded. I mentioned in my speech that we will be focusing on delevering the balance sheet just as we did in 2022. That will be a focus in 2023, because we think that creates options for the business in due course. So we will be focusing on that as well. And all of that is achieved, not just by maximizing the revenue part of the equation but also keeping a close control on the cost that we spend otherwise in the mine in conjunction with the partners. So yes, investment in both, significant reduction in debt is what we would hope to achieve in 2023, but to not compromise our ability to invest in the growth project. Mark, is there anything you'd like to add to that?
Mark Wall
That's right. And I think Stacey, perhaps I would add that where we're fortunate to have bondholders that we know and we know that they're both thoughtful and sophisticated bondholders who we're able to talk with around options of application of capital to growth. Now, we want to return capital to our bondholders, because that's what we've committed to do. At the same time, we are able to engage with our bondholders and they are well known to us. So we're able to have very good and rational discussions. So we're confident that we'll be able to fund through the platform that we see in front of us.
Matt MacPhail
Okay, excellent. I've got a set of two questions from Mr. Michael Wan [ph]. First question, when do management expect a debt to EBITDA ratio of 1 to 1 to be achieved? And then the second part of the question, what steps are being taken to market the company to investors and address the heavily discounted share price?
Mark Wall
I guess on the first one -- thanks, Michael. I hope you're well. On the first one, giving a specific date, directionally that's where we want to go. Of course, we've got -- getting U.S. dollars and where we've got costs in Canadian dollars, which can be a good thing with a positive FX rate. But we're reporting our revenue in Canadian dollars. So I'd have to take a guess on exchange rate. I'd have to take a guess on diamond price on a range of things. So we've purposely said that we want to directionally move towards a better EBITDA ratio of 1 to 1. Giving an exact date of when we'll do that would be too many variables for me to guess that, although Steve’s welcome to come in and take a shot if he would like. Your second point is a point that multiple investors have discussed with me and it's obviously a hot topic. We've reported $177 million of adjusted EBITDA against the share price that is significantly less than that. And yes, we need to do more to continue to market the company, to communicate externally the company and the prospects of the company. We will be in London in April to be doing that. We’re in discussions with different individuals around how we can more effectively market the company. We too are frustrated with the share price of the company. And I agree with you that we need to do more and we will do more to market the company externally to get value into the share price. Steve, do you have anything to add?
Steven Thomas
Mark, I wouldn't. So I will stick to that answer. Many variables driving our future financial cash flow that will feed into getting the debt down and therefore not sensible to put a specific date on it, that's the direction we're heading and that's our intent.
Matt MacPhail
Okay, great. I have now a question from Kieron Hodgson of Panmure Gordon. And the question reads, have there been any surprising trends in diamond demand during Q1 2023 beyond what had been anticipated?
Mark Wall
Reid, that one sounds like it's in your purview.
Reid Mackie
Yes. Thanks, Kieron. It's a good question. I would say that the sustained, and I mentioned in the talk and we did see it through 2022, but I would say that we are seeing -- and I don't know if I'd call it a surprise, but continued upward price performance in the small, cheap and brown colored diamonds that we have a fairly large position in at Gahcho Kué. The sustained increase is a welcome surprise. Maybe we shouldn't have been surprised by it with the absence of Argo, with what's going on with increased sanctions on diamonds coming out of Russia. I think it's also becoming a more important input into manufacturing centers in India right now. All those elements combined are helping to sustain the price growth of that product area for the medium term. And we're seeing right through the pipeline increased usage of those goods right down to the retail and jewelry design. So I think that's important. Another welcome, and again I wouldn't call it a surprise, but it is a new development is -- or it's become more important is how provenance and traceability platforms are now looking at smaller or going down to smaller sizes. Before it was kind of a 1 carat up type of venture. We're seeing increased interest in guaranteeing provenance and certainly provenance of our goods, Canadian source product that will travel with diamonds like ours right down to the consumer level is becoming increasingly sophisticated. And it's obviously welcome from what we're seeing so far in 2023. And I would expect to continue with maybe a little bit of an earlier push for replenishing stock certainly out of Asia. So it's something to watch this space to see if it continues through here, but definitely also an additional welcome development.
Matt MacPhail
Okay. Thanks, Reid. And now I have one final question from the webcast. And the question is from Andreas Amarin [ph]. And the question reads, what is the rough timeline until you will have enough data to decide how to go forward with Hearne? Mark, do you want us to --
Mark Wall
Sure. Go ahead, Matt.
Matt MacPhail
Okay. So as I mentioned before, throughout the kind of latter half of 2023, we hope to be able to share more information with the market as we progress both the drilling campaign at Hearne and the internal study, which we're working on, and this level of study is going to inform the next stage gate of investment decision around find process Kimberlite tailings and placement and things like that. So there are a few stage gates that we need to get through. And they will -- the next one we expect is at the end of '23. And then there'll be another stage gate, so full commitment to investment. I don't think we'd be making a full decision for underground before the end of 2024 at the earliest. But every level of stage gate decision is going to increase our confidence and the accuracy of our economic outcome. So the market will be well informed of all of these activities as appropriate.
Mark Wall
Thanks, Matt. And still got [ph] little perhaps that towards the end of this year, we'll have a very good idea of where we're at with this project. And Matt’s right. There are some technical hoops to jump through. But by the end of this year, we'll have a pretty good idea of where we're at. And we'll be able to update everyone and the market and shareholders on that that will then lead us into that very detailed phase that Matt raises.
Matt MacPhail
Okay, that's all the webcast questions I have operator.
Mark Wall
Okay. Well, thanks everyone for your questions. It's very good to take questions. We enjoy taking questions. So please, when we have the next call, don't be shy. Thanks everyone for dialing in. And we look forward to updating you again soon.
Operator
Thank you. That does conclude our conference for today. Thank you all for participating. You may now disconnect.
