A Mining Analyst and a Junior Producer Go Head to Head
Contributed Opinion

Share on Stocktwits


Mining analyst Kees Dekker, Atlantic Gold and The Critical Investor engage in a discussion about Dekker's analysis of the junior gold producer.

1. Introduction

The Critical Investor: After doing a pretty interesting interview with my Dutch fellow countryman Kees Dekker, it is time to show an example of his analyst reports. This is a critical analysis of a new junior gold producer, Atlantic Gold Corp. (AGB:TSX.V). This company was actually one of my favorite holdings for a long time, despite this I no longer have it in my portfolio as I view it to be fair valued since Q2, 2018. The basis for this article is an analysis privately made by Kees, and after I got to read this report it seemed interesting to me to contact Atlantic Gold management, in order to see if they would provide constructive feedback.

Fortunately they did, and the result is an analysis with several rounds of feedback by both Atlantic and Kees. Yours truly also added several questions, opinions (sometimes differing from Kees and/or Atlantic as we all have different views) and remarks here and there, as I love doing this anyway, but also in an attempt to provide more reference, and get things more clear for myself and the audience. As the combined analysis with feedback resulted in a 45-page article, my syndication websites deemed it much too long for publication, so I decided to have it syndicated by providing just the executive summary with feedback. The full-length article including feedback can be found soon on my own website,

2. Executive Summary

Atlantic Gold Corp. (AGB:TSX.V) is a Canadian gold mining company, which has a number of projects in Nova Scotia, Canada, together referred to as the Moose River project. After acquiring in August 2014 the first two of these projects, Touquoy and Cochrane Hill, Atlantic rapidly proceeded to acquire two more projects, Beaver Dam and Fifteen Mile Stream, close to Touquoy. The combined projects had sufficient critical mass to be developed to a mine and construction at Touquoy was given the go-ahead mid-2016. Commercial production was reached on 1 March 2018, which was within budget and on time.

The market has greatly rewarded Atlantic Gold's performance by increasing the share price five-fold since February 2016.

This study has had great problems with reviewing the business plan to determine whether the share price performance and current capitalization are properly underpinned by the intrinsic values of the projects. The 2018 technical report, which purports to substantiate the merits of the Moose River project, is basically a cobbling together of two reports.

Atlantic Gold commentary: This is not correct. The recent report published in 2018 supports the disclosure of new Mineral Resources and Mineral Reserves at Fifteen Mile Stream and Cochrane Hill underpinned by new drilling, resource models, metallurgical testwork, operating costs, pit designs, plant design, and all other modifying factors that must be considered when assessing economic viability.

The first study, completed in 2015, is about production starting from Touquoy and the adjacent Beaver Dam deposits (referred to as Phase 1). The other part of the report deals with production from 2021 onwards from Fifteen Mile Stream, followed by Cochrane Hill (referred to as Phase 2 Expansion). The cobbling-together approach to the combined study report is evident from Phase 1 parameters not having been updated, even including the forecast capital expenditure in 2016 and 2017.

Atlantic Gold commentary: We stated in the technical report that we would update the numbers once we had 12 months operating data.

Response Kees Dekker (KD): It still makes for mixing outdated information into a new study.

The cash flow report refers to Year 1, Year 2, etc., rather than giving actual calendar years.

Atlantic Gold commentary: Please refer to the detailed explanations relative to NI 43-101.

(The Critical Investor (TCI): Atlantic provided a detailed document confirming it did comply with regulations).

Response KD: I am confident that you fully adhered to NI.43-101 regulations, otherwise you would not have been allowed to publish. However, if the purpose of technical reports is to fully inform the reader, one should include a lot more. The limitations of NI 43-101 requirements are, for example, evident by the gross majority of producers being able to consistently publish "reserves" yet rarely able to pay dividends. Basically the mines/projects at best sustain themselves most of the time. Often shareholders need to chip in to keep the companies afloat.

Atlantic Gold commentary: The company is generating substantial free cash flow.

TCI commentary: I have to admit that actual capex could have been updated in this combined report, with opex pending for the first full year of production. Using one quarter of opex figures of a ramping up mine was not helping anyone in my view, so it made sense to wait for a full first year of production data.

The review of the report raises a number of concerns, such as:

  • The grade of estimated resources is heavily influenced by only a few high-grade to very high-grade composite values. These have not been capped, or their influence on the grade of surrounding blocks limited. The average grade of the two Touquoy deposits planned to be mined first is better supported by many assays and less affected by a few high-grade values. Any plant feed grade problems may therefore only become apparent in future. In this respect early indications of problems with are the actual feed grade in 2018. This has been 1.35 g/t for the first six months and lower at 1.28 g/t in the June quarter. The milled grade is exactly as forecast at 1.35 g/t for the full year. However, of ore mined 49% was stockpiled at a grade of 0.51 g/t (see MD&A Q2 2018), which is much lower than the planned 0.78 g/t Au. When back calculating, this indicates that the average grade mined was 0.96 g/t Au, which is far below planned mined grade of 1.30 g/t Au for the full 2018 year as is shown in the table below.

    Atlantic Gold commentary: The lower grade in H1 2018 was due to the mine having to modify its working sequence because of the removal of historic tailings that required removal procedures to be approved by the provincial regulators.

    Response KD: The explanation by Atlantic Gold management that the lower grade was due to the mine having to modify the working sequence, because of the removal of historic tailings does not explain the lower grade, at best the fact that equipment had to be used for tailings removal and not available for mining ore and waste and the lower the planned strip ratio.

    TCI Commentary: The company tried to explain this in the MD&A of Q2 2018:

    "During the first half of 2018, a total of 1,852,353 tonnes of ore were mined, at a waste to ore ratio of 0.85:1 with a total of 3,421,473 tonnes of material moved. Approximately 49% of the ore mined in the first half of 2018 was stockpiled as low and medium-grade material which will be readily available for processing later in the mine life. This material was assumed to be waste in the 2015 Feasibility Study. Waste material was used to build the Tailings Management Facility (TMF) and the waste dump with its ditches and water collection area."

    Wrongly assuming waste to this degree is worrying in my view. The chances of mis-categorizing ore as waste and vice versa seem significant when using the uncapped high-grades with a large search radius to influence neighboring block grades. These high grades have a nugget component of 80% of the grade. Therefore the risks of much lower average grade than forecast are real, and I am really wondering if Atlantic can mine as selectively as it says.

    Response KD: How can moving tailings have anything to do with the grade of ore mined? Refer to the table above; noticeable is that they have mined much less waste than planned, probably to be able to hit ore mining harder (twice planned rate!) to get sufficient higher grade blocks to achieve planned mill grade. This points to them having grade trouble, I have no doubt about that.

    Atlantic Gold commentary: It should be noted that the 2015 FS did not include a stockpiling strategy, which was developed in 2017 to consider both pit discard and economic cut-off grades based on known costs. Grade control drilling on a 5m x 5m pattern is used for ore/waste definition not the resource model. For the year to date grade control model to mill reconciliation is within 1%. Reconciliation is done to bullion. On selectively, the author offers an opinion not facts.

    Atlantic Gold commentary: On the estimation: To say "the grade of the estimated resources is heavily influenced by only a few high-grade to very high grade composite value" is to pass naïve comment on almost all gold deposits where the sample Coefficient of Variation exceeds 2, which includes probably 99% of all gold deposits. Yet there are many gold deposits in production today and over the past 20 years with these characteristics—and which are using or have used the same or very similar approaches to resource estimation and production as the Touquoy Deposit—and have performed very well in production. There are no strong reasons to expect that these characteristics of the Goldenville style gold mineralization will have a stronger negative influence on profitability in these deposits than anywhere else. Finally, production in the first year was focused on the eastern part of the pit, not the west side. The western portion was developed early as a quarry to extract waste used in the roads and tailings dam construction.

    Response KD: Yes, the coefficient of variation (CV) of gold deposits is typically higher than 2, but in the case of Moose River project quoted between lowest at 4.15 (Domain1 Touqouy) to highest at 10.3 (Egerton/Plenty). With respect to Touqouy there is much less concern as the 90-percentile variogram has a much lower nugget component. The concern revolves mainly around the other deposits with higher CV and 90 percentile variograms with very high nugget component. The estimation approach for these did however not cap high grades and put no restrictions on search dimension, which is often used for other deposits. In this way a few very high-grade samples will have a large effect on average grade. Given that initial mined production has a much lower grade than planned indicates that the concerns raised are valid, even for Touqouy, which was deemed less risky than the other deposits.

    TCI commentary: Canadian Malartic stays below 2 and Detour sits around 3, I believe, but both don't rely on high grade as much. The MRC FS states at p.14-7: "A cumulative histogram of the mineralized 2 m composite gold grades indicated that grades are strongly positively skewed with a coefficient of variation of 9.4, indicating a high proportion of very low-grade samples and a small tail of high composite grades greater than 100 g/t Au. The maximum composite grade of 257 g/t Au is some 490 times the average composite grade for the data set. An evaluation of the conditional statistics indicated that the 95 highest-grade composites account for approximately 48% of the total gold content of the composites." I must say this inclusion and gold amount of uncapped samples doesn't instill a great deal of confidence but adds risk, and I believe (as myself being a non-geologist) that Kees could be on to something here, certainly taking into account the apparent mis-categorization of ore as waste.

    Atlantic Gold commentary: Irrelevant as the grade control model is used for planning purposes. Moreover, there was no miscategorization of ore and waste; the stockpiling strategy had not been defined at the time of the FS.

    TCI commentary: I am also wondering if mining low grade ore isn't much more expensive than stripping waste at this project.

    Atlantic Gold commentary: The difference between ore and waste mining is in the order of $0.03/tonne.

  • The plant feed grade assumes very low unplanned dilution, whereas the chosen small selective mining unit (SMU) introduces much risk of such unplanned dilution.

    Atlantic Gold commentary: The author does not take into account that short-range planning is based on the grade control model built with data on a 5m x 5m grid. Moreover, ore and waste are blasted separately to better reduce dilution. Approximately only 20,000 tpd are mined using relatively small equipment (in the mining space) including excavators as opposed to shovels. Ore width often exceeds 30m.

    Response KD: Extra attention and mitigating measures may help, but in practice selective mining and unplanned dilution are bedmates.

    TCI commentary: Canadian Malartic has a mining dilution of 8%, ore loss I believe 0% but not sure, study didn't say ore loss but just no mining loss. Detour has a mining dilution of 3.8%, and ore loss of 5%.The numbers of Atlantic are mining dilution of 1.6% and ore loss also 1.6% (98.4% mining recovery). Forecasted recovery is 98.4%, which was very high, in reality it has 94.7% for H1 2018. Detour has 91.2% and Malartic 88.6% for FY2017 and had 89.4% planned in the FS.

    Atlantic Gold commentary: Comparing 200,000 tpd operations that use large shovels and trucks with a 20,000 tpd operation using excavators with small buckets does not apply.

  • The pit designs have been based on pit shells that are very sensitive to small changes in input parameters. At the current gold price they are certainly sized too large, irrespective of the risk of underestimating operating cost (see more on this below).

    Atlantic Gold commentary: Taking into account the Canadian dollar gold price that the pits were optimized on (~CDN$1450 for Phase 1 and ~CDN$1600 Phase 2) the change to today's Canadian dollar gold price of ~CDN$1580 is not that significant. Higher cut-off and discount rate used for pit optimization therefore conservative.

    Response KD: The cut-off grade is higher is higher than what? The reserves were established based on a cut-off grade of 0.40 g/t Au, which is substantially lower than the 0.5 g/t cut-off grade used for resources. An 8% discount rate is appropriate at this stage.

  • The production schedule assumes that stockpiling is such that material can be reclaimed with much higher grade than the average grade. It is very doubtful this can be achieved without much additional grade control effort and expense.

    Atlantic Gold commentary: Scheduling assumed high and low-grade stockpiles would be created. The reclaiming of stockpiles targets the high-grade stockpile initially followed by the lower grade; however, this was summarized in the technical report as a single stockpile.

    Response KD: The point I am making is that this will require additional grade control and stockpile management, which will add to expenses.

    Atlantic Gold commentary: No additional grade control as all material to be mined is going to be grade controlled as per budget. And it was always the case in the projections. Stockpile management or waste dump management are pretty much equivalent in terms of operating costs except for a small re-handle cost.

    TCI commentary: To what extent would opex rise with this grade control compared to no grade control? I don't believe that Malartic has grade control. Detour has grade control as well, don't know to what extent though.

  • This study shows that the mining cost suggested by Atlantic Gold is much lower than actual cost at the much larger Detour operation with a simpler mining process and using much larger mining equipment and much lower than the Canadian Malartic operation in H1 of 2018 based on reported figures. Moreover, initial actual Q2 2018 operating unit costs are clearly higher than forecast for Touquoy.

    Atlantic Gold commentary: Comparing the mining costs at Detour with Moose River is like comparing apples with pineapples. Detour is by no stretch of the imagination a simpler operation despite the higher mining rate. Also, Detour has higher fuel costs, longer haulage distance and much higher labor costs due to the FIFO nature of its operations. Mining costs at MRC are well-known since Atlantic has the benefit of more than two years of operating data. Mining cost/t is a bit lower than the PFS, G&A/Processing is a bit higher due to above expected maintenance, but the company is actively working on a large number of tweaks and improvements. The Feasibility study has $9.00 to $10.00/tonne processing cost. We expect the costs to vary between $10.00 and $12.15 depending on the maintenance required. Higher costs are mostly on maintenance while we make tweaks to the crushing circuit and also labor costs because we are building capacity and capabilities for the other projects.

    Response KD: I record that no benchmarks are provided to show that the Detour and Canadian Malartic numbers are not representative. The actual Q2 operating cost of Moose River indicates an overrun of 10%.

    TCI commentary: The study mentions C$690/oz AISC on average, for H1 2018 realized is C$746/oz so looks higher although still first year so I consider this very decent. The excessive low grade stockpiling points to underlying issues though, in my view.

  • Atlantic Gold suggests that the operating cost at Phase 2 operations, which are at some distance from Touquoy and require extra handling and transport cost, are lower than for Touquoy. This is not sufficiently substantiated and deemed not credible.

    Atlantic Gold commentary: Phase 2 is based on production of a gold concentrate at both Fifteen Mile Stream and Cochrane Hill, which is transported to Touquoy for final processing. Reduced costs associated with concentrate production can be attributed to the following:

    • Incorporated "Hydrofloat" technology allowing larger grind size thus reducing grinding costs.
    • Reduced reagent costs compared to Touquoy.
    • Transportation costs significantly reduced due to transporting concentrate vs. run of mine ore.
    • Optimization of personnel across projects.

    Response KD: The reagent cost will be beneficially lower for treating concentrate compared to gravity tailings at Touquoy/Beaver Dam, but unlikely to be that much lower as provided for. Against the advantages stand regrinding of concentrate, transport to and double handling at the Touquoy plant. Given the modular nature of the expansion, little prospect for economies of scale

    Atlantic Gold commentary: Author cannot support that assertion without a full understanding of detailed costs.

  • The business plan looks very much a paper exercise and is not practical as the graph below illustrates.

    Forecast Total Material Mined Over the Life of Mine

    The planned expansion is for tripling of plant throughput.

    Atlantic Gold commentary: This is not correct. For the purpose of the study throughput is planned at 2,000,000 tonnes (and is not tripled). Pre-concentration plants will be constructed at Fifteen Mile Stream and Cochrane Hill with a throughput of 2,000,000 tonnes each. This will require transporting 50,000 to 70,000 tonnes of concentrate per year to the Touquoy processing facility.

    Response KD: Yes, that is when considering the throughput at Touqouy only. I will rephrase accordingly to bring out that it is a tripling in the comminution rate.

    TCI commentary: This AG comment feels like semantics, in the end three plants of 2,000kt each are build, and only Touquoy has the final processing facility to handle the concentrates of FMS and CH. To build three mills and crushing circuits (three standalone operations) each lasting five to six years does sound inefficient. But bottom line the post-tax FS IRR of about 28-30% @$1200/oz Au is good for a gold mine, if realized of course.

  • Theoretically this schedule is achievable, but it is a very inefficient approach with the company having to use contract miners, alternatively staff and equip up for a few years, to retrench and dispose of the equipment soon thereafter. The schedule should be seen as impractical.

    Atlantic Gold commentary: We do not use contract miners. This is an impractical schedule only if you are not an operator. Production is from four separate operations. Phase 1 will see equipment utilized between TQ and BD. FMS and CH will be separate operations requiring their own fleets to be utilized over a five-year mine life.

    Response KD: I do not follow the reasoning. When you want to increase overall plant feed, no matter from where it is derived, mining rates will have to increase dramatically requiring additional equipment and staff for those years. Redeployment is possible between operations when one reduces/closes down and another starts up.

  • The business plan looks even less practical when considering the forecast cash flow using the gold price of US$1,199/oz and exchange rate of C$1.29/US$ at 3 October 2018 shown in the diagram below.

    Cash Flow Forecast – Atlantic Gold

    The above graph shows that the company's financial performance is totally dominated by having to ensure it has the required funding to develop first Fifteen Mile Stream and a year later Cochrane Hill. Once constructed the Moose Rover project has five years life left should it not be very successful in identifying additional reserves.

    At the share price of C$1.59 on 3 October, Atlantic Gold has a market capitalization of C$376 million. When accounting for dilution and net current assets, but ignoring the effect of loan servicing because the cash flow model has accounted for this, an Enterprise Value of C$370 million (US$287 million) is derived. This is almost 40% higher than the net present value of the cash flow model, which is C$266 million for a discount rate of 7.5%. This value was derived assuming that the very low operating cost rates proposed by Atlantic Gold are valid.

    TCI commentary: I would like to see the DCF model provided by Atlantic to see exactly what is going on, also mostly all economic studies have one. The sensitivity in the study generates a post-tax NPV of around C$370M @$1200/oz Au. However, in my opinion the value of a producer is much better indicated by P/CF multiples (P is share price, CF is operational cash flow annualized per share). Atlantic is operating at about a CF of about C$80 million annually now, which implies a P/CF of less than 5, which is low for a low-cost, good-jurisdiction producer (8-10 is more standard). But on the other hand, the company has to re-invest internal CF for phase 2 so this limits FCF output in 2020-2021; it might have grade issues and it has additional ramp up risks of three new pit operations.

3. Conclusion

In conclusion, this valuation points to Atlantic Gold being heavily overvalued, irrespective of the many concerns. Overvaluation of producing companies is a feature of the equity markets. That is why this report emphasises not the overvaluation, but the concerns about the business plan, which could mean that the calculated value of C$266 million, based on the inputs of Atlantic Gold, is far too high.
