Research: Metals & Mining
Wheaton Precious Metals (WPM) released its Q422/FY22 financial results in the context of known production and sales volumes. As a result, financial results were very close to our prior expectations for both Q422 and FY22. The main (positive) variances were in depletion (US$3.3m) and ‘other’ income (US$1.9m), to result in net earnings that were US$5.0m better than our prior forecasts for both periods (equating to a positive percentage variance of 5.1% for the quarter and 1.0% for the full year; see Exhibit 2).

Making headway despite headwinds
WPM’s results were achieved despite at least five of its major contributing mines (Salobo, Antamina, Penasquito, San Dimas and Voisey’s Bay) mining through coincidentally lower-grade sequences in Q422. Despite such headwinds, other features of its Q4 results were general and administrative expenses that were lower than guidance for the eighth quarter in succession and silver stocks that are now at their lowest level (in terms of months of production) since Q416.
Growth picking up after FY23
Given WPM’s guidance, FY23 seems likely to be year of investment and steady output for Wheaton (we estimate 623.7koz gold equivalent production in FY23 cf 638.1koz in FY22). However, we expect growth in production to pick up smartly thereafter, to reach 852k gold equivalent ounces by FY27.
Valuation: Little changed but marching upwards
Using a CAPM-type method to value WPM and applying a nominal discount rate of 9.0% to cash flows implies a ‘terminal’ valuation for WPM at end-FY26 of US$53.28 (C$73.22) per share, assuming zero subsequent long-term growth in real cash flows and 4% inflation, and a valuation now of US$41.11 (C$56.49) per share. To this should then be added end-FY22 net cash of US$1.54/share (C$2.11/share) to take the total to US$42.65 (or C$58.60) per share. Otherwise, assuming no purchases of additional streams in the foreseeable future (which we think unlikely), we calculate a value per share for WPM of US$54.47, or C$74.85 or £44.83 in FY26, based on a 30.4x historical multiple of contemporary earnings. In the meantime, WPM’s shares are trading on near-term financial ratios that are lower than those of its peers on 63% of common valuation measures if Edison forecasts are used or 55% if consensus forecasts are used. If WPM’s shares were instead to trade at the average level of its peers, then we calculate that its FY23 share value would be US$45.94, or C$63.13 or £37.81, rising to US$47.42, or C$65.15 or £39.03, in FY24 (based on Edison forecasts).
Q422/FY22 results
Wheaton’s Q422/FY22 financial results were released in the context of production and sales volumes having already been pre-released to the market on 21 February. Final sales volumes were exactly in line with the earlier announcement, while the vast majority of a very small difference between the two announcements in gold production could be attributed to production at Sudbury in Q3 and Q2 being retrospectively restated downwards in Q422. A summary of the differences is provided in the table below:

Variance is actual cf forecast. *Excluding impairments, impairment reversals and exceptional items. **Forecasts now include stock-based compensation costs. ***Cobalt inventory is held on WPM’s balance sheet at the lower of cost and net realisable value; cash cost per pound of cobalt sold during Q422 included an inventory impairment charge of US$1.6m, which resulted in an increase in cash costs of US$8.71/lb. Totals may not add up owing to rounding.
At the level of the individual mines, in general, at least five of Wheaton’s major contributing mines (Salobo, Antamina, Penasquito, San Dimas and Voisey’s Bay) were mining through coincidentally lower-grade areas as part of their mine plans, while the grade at Constancia, despite being higher, was lower than expected. Nevertheless, five mines (Zinkgruvan, Minto, Antamina, Stillwater and Sudbury) noticeably outperformed our expectations in terms of either production or sales or both for the quarter.
Ounces produced but not yet delivered
At 11.8%, the degree of under-sale of silver during Q422, relative to production, was below our prior expectation of 7.8%, but was almost exactly in line with the (prior) long-run average of 11.9% (from Q112 until Q322). The 1.6% under-sale of gold relative to production was similarly slightly below our prior estimate of a 4.5% over-sale, but was noticeably above the prior long-run average of a 6.7% shortfall (Q112–Q322) and possibly indicative of some ‘flushing through’ of sales by Wheaton’s counterparties before the year’s end:
Exhibit 3: Over/(under) sale of silver and gold as a percentage of production, Q112–Q422 |
Source: Edison Investment Research, WPM. Note: As reported. |
Gold and silver ounces produced but not yet delivered as at 31 December amounted to 63,601oz and 3.4Moz respectively (cf 67,247oz and 3.6Moz at end-Q322). These were both below our prior estimates (see our note: Adjusting for ‘major maintenance’ at Salobo in Q4, published on 3 March 2023) of 64,275oz Au and 4.0Moz Ag and equated to 2.62 months and 1.41 months of FY22 gold and silver production, respectively (cf 2.63 months and 1.77 months estimated as at end-Q322) and compare with WPM’s target levels of two to three months for gold and palladium and two months for silver (see below).

General and administrative expenses
At the time of its Q122 results, WPM provided guidance for non-stock general and administrative (G&A) expenses of US$47–49m or US$11.75–12.25m per quarter (cf US$42–44m or US$10.5–11.0m per quarter for FY21 and US$40–43m in FY20), including all employee-related expenses, charitable contributions, etc, but excluding performance share units (PSU) and equity settled stock-based compensation. In the event, at US$11.3m, non-stock G&A expenses in Q422 were below the bottom of the range implied by guidance for the eighth quarter in succession.

Given the performance of WPM’s shares during the quarter, stock-based G&A expenses in Q422 were almost exactly in line with our prior estimate for the quarter (as shown in Exhibit 6, below):
Exhibit 6: Graph of historical share price move (US$/share) versus quarterly stock-based G&A expenses, Q419–Q422 |
Source: Edison Investment Research (underlying data: Bloomberg and Wheaton Precious Metals) |
The analysis of stock-based G&A expenses over the past 13 quarters relative to the change in WPM’s share price (also in US dollars) continues to exhibit a close Pearson product-moment (correlation) coefficient between the two of 0.79, which remains statistically significant at the 5% level for a directional hypothesis (ie there is less than a 5% probability that this relationship occurred by random chance) and this therefore continues to form the basis of our quarterly and full-year forecasts for G&A expenses in Exhibit 9.
FY23 and five-year and 10-year guidance
At the time of its 21 February production and sales announcement, Wheaton also provided detailed production guidance for FY23 (for the first time), as well as for the five years from FY23–27 (inclusive) and the 10 years from FY23–32 (inclusive). These remain unchanged and are presented in the exhibit below compared with Edison’s equivalent forecasts. Note that both include the Marathon, Curipamba and Goose streams (but not yet the Fenix stream) and exclude the Keno Hill and Yauliyacu streams (which have now been sold).

Source: WPM, Edison Investment Research forecasts. Note: *Edison forecasts include Salobo III from FY23, Rosemont/Copper World from FY27 and Antamina extension from FY28.
WPM’s updated five-year and 10-year guidance is based on standardised pricing assumptions of US$1,850/oz gold (cf US$1,800/oz previously), US$24.00/oz silver (unchanged), US$1,800/oz palladium (cf US$2,100/oz previously) and US$18.75/lb cobalt (cf US$33.00/lb previously). Of note in this context is an implied gold/silver ratio of 77.1x, which compares with its current ratio of 86.7x, but a long-term average of 61.5x (since gold was demonetised in August 1971). At the standardised prices indicated, our gold equivalent production forecast of 623.7koz gold equivalent (AuE) for FY23e lies well within WPM’s guidance range of 600–660koz AuE.
Otherwise, readers will note that Edison’s medium-term production forecasts are within 5% of WPM’s guidance for the period FY23–27 and within 7% of its longer-term guidance for FY23–32. However, we regard this as within an acceptable range of variance, especially given WPM’s traditional under-sale of metal relative to production of this order of magnitude. In addition, these estimates necessarily exclude potential future stream acquisitions.
Growth opportunities
Short term
In the short term, production of palladium and gold at Stillwater (operated by Sibanye-Stillwater) will increase under the influence of the Fill-the-Mill project at East Boulder (although the Blitz project has now been delayed to 2024, following the suspension of growth capital activities owing to COVID-19). Similarly, the Voisey’s Bay underground project is ramping up to full production, while First Majestic is increasing production at San Dimas by restarting mining operations at the past-producing Tayoltita mine to add another 300tpd (12%) to throughput. In addition, it has been investigating the installation of a 3,000tpd high-intensity grinding mill circuit and an autogenous grinding mill to improve recoveries and reduce operating costs.
Medium term
In the medium term, Wheaton has four projects that are progressing on their route to production:
■
Sabina Gold & Silver Corp (in the process of being acquired by B2Gold) has announced a formal construction decision for the Goose project with the intention of commencing full construction early this year with first production anticipated in 2025.
■
On 9 March, Artemis announced the approval of its BC Mines Act Permit for the Blackwater project, which is the last major permit required ahead of major construction work. Last year, the company announced the start of site preparation work at the plant site, including site clearing, bulk earthworks and sediment/erosion control, which is reported to be ‘well advanced’. Since then, it has executed an order for construction equipment with the initial fleet expected to be delivered in early Q223. It has also now closed the associated US$385m project loan facility, with first gold now anticipated in H224.
■
In November, Generation Mining received the final environmental approvals for its Marathon palladium-copper project in northern Ontario. This year, it is aiming to secure key provincial permits, related to species at risk, tree harvesting and water quality, etc, so that early construction works can commence. The start of construction is anticipated in Q323 and production in Q3–Q425, to which end it has already purchased an unused, surplus SAG mill and a ball mill.
■
Adventus Mining signed the investment contract for the Curipamba project with the Ecuadoran government in December and is planning for the start of formal construction of the project in Q223.
Long term
Salobo
On 24 October 2018, Vale announced the approval of the Salobo III brownfields mine expansion, intended to increase processing capacity at Salobo from 24Mtpa to 36Mtpa, with start-up at that point scheduled for H222 and an estimated ramp-up time of 15 months. According to its agreement with Vale at the time, depending on the grade of the material processed, WPM was to have made a payment to Vale for this expansion, subject to a 90-day completion test, which WPM estimated was to have been in the range US$550–670m in FY23–25, in return for which it was to be entitled to its full 75% attributable share of expanded gold production.
After the end of the quarter however, Wheaton and Vale agreed to amend the Salobo Precious Metals Purchase Agreement (PMPA) to adjust the expansion payment terms to provide increased flexibility for the ramp-up of the expansion, while also maintaining an incentive for Vale to maximise grade on an annual basis. The expansion payment will now be phased, with Wheaton making an initial payment once actual throughput is expanded above 32Mtpa and a second payment if actual throughput is expanded above 35Mtpa, by 1 January 2031. The total cumulative payments will range from US$283m to US$552m, dependent on Vale’s timing for each of the production increases, and Edison now forecasts that Wheaton will make total payments to Vale of US$552m by the end of FY24. In addition, Wheaton will be required to make annual payments of between US$5.1m and US$8.5m for a 10-year period following payment of the expansion payments if the Salobo mine maintains a high-grade mine plan.
These payments compare to WPM’s purchase of a 25% stream from Salobo in August 2016 for a consideration of US$800m (see our note Going for gold, published on 30 August 2016), the US$900m it paid for a similar stream in March 2015 (when the gold price averaged US$1,179/oz) and the US$1.33bn it paid for its original 25% stream in February 2013.
As at the end of Q422, the Salobo III mine expansion was reported to be 99% complete:

According to Vale, the project successfully commenced at the end of 2022 and is expected to achieve full capacity in Q424. Once Salobo III has been completed, however, WPM believes that reserves and resources there could support a further 33% capacity increase at Salobo, from 90ktpd to 120ktpd (denoted Salobo IV). In addition to its long-term underground potential, WPM believes such an expansion could nevertheless still be supported by open-pit mining alone. Under the terms of its agreement with Vale, there would be no additional payment due from WPM in respect of the Salobo IV expansion.
Rosemont/Copper World
Another major project with which WPM has a streaming agreement for attributable gold and silver production is Rosemont in Arizona (now part of the wider Copper World complex).
Rosemont/Copper World is near a number of large porphyry-type producing copper mines and will be one of the largest copper mines in the United States, with initial output of c 86,000t copper per year from mined sources, accounting for c 8% of total US copper production, rising to c 101,000tpa after 16 years. Total by-product production of silver attributable to WPM is estimated to be c 1.7Moz Ag pa for Phase I, followed by c 2.4Moz Ag pa for Phase II.
The evolution of the project from Rosemont to Copper World
In March 2019, Rosemont/Copper World’s operator, Hudbay, received both a Mine Plan of Operations from the US Forest Service and a Section 404 Water Permit from the US Army Corps of Engineers (ACOE), which was effectively the final material administrative step before the Rosemont mine could start development. Subsequently, Hudbay indicated it would seek board approval to start construction work by the end of CY19, which would have enabled first production ‘by the end of 2022’. In the meantime, it started early works to run concurrently with financing activities (including a potential joint venture partner).
A legal challenge, lunched in July 2019, has since delayed the project. However, Hudbay has continued to explore in and around the area of the mine and, on 22 September 2021, announced the intersection of additional high-grade copper sulphide and oxide mineralisation predominantly located on its wholly owned patented mining claims (denoted Copper World). To date, seven deposits have been identified at Copper World with a combined strike length of over 7km and, on 15 December 2021, Hudbay announced a maiden mineral resource at Copper World of 272Mt in the indicated category and 142Mt in the inferred category, both at an average grade of 0.36% copper. The mineralisation consists of both skarn and porphyry copper sulphides with a significant oxidised component along a regional fault along the west side of the Rosemont, Bolsa and Broad Top Butte deposits known as the Backbone Fault. As a consequence of this exploration, it was determined that approximately 33Mt of inferred mineral resources at the Bolsa deposit, which were previously considered to be waste in the resource pit shell used for Rosemont’s NI 43–101 feasibility study, could now potentially be converted into reserves, which would result in less waste being mined at Rosemont, thereby reducing costs and energy consumption per tonne of ore mined. In addition, the Rosemont deposit also contains oxide mineralisation that was previously classified as waste, which could be processed with the oxide mineralisation at Copper World, and it is expected that further synergies will be identified as Hudbay explores the gap between Bolsa and Rosemont. Note, the Copper World discovery is included in WPM’s area of interest under its precious metals purchase agreement (PMPA) with Hudbay.
A new development plan
As a result of these discoveries, Hudbay has adjusted its plan to develop the district. Among other things, it has now acquired a private land package totalling approximately 4,500 acres to support an operation on private lands. The initial technical studies for Copper World were incorporated into a preliminary economic assessment (PEA) investigating the development of the Copper World deposits in conjunction with an alternative plan for the Rosemont deposit, which was announced to the market on 8 June 2022, and proposed a two-phase mine development plan. The first phase of the mine plan requires only state and local permits and reflects an approximate 16-year mine life. The second phase then extends the mine life to 44 years and incorporates an expansion onto federal lands to mine the entire Rosemont and Copper World deposits. The second phase of the mine plan will be subject to the federal permitting process and the company expects that it will be able to pursue the federal permits within the constraints imposed by the courts’ most recent legal decisions if any subsequent appeals are not successful.
In this context, on 24 May 2022, Hudbay received a favourable decision from the US District Court for the District of Arizona on all issues relating to the development of Copper World, including that Copper World and Rosemont are not connected under the National Environmental Policy Act (NEPA) and, therefore, that the ACOE does not have an obligation to include Copper World as part of its NEPA review of Rosemont. The District Court also granted Hudbay’s motion to dismiss the Copper World preliminary injunction request filed by the plaintiffs in the two lawsuits challenging the Section 404 Clean Water Act permit for Rosemont on the basis that the lawsuits were moot after the company surrendered its 404 permit back to the ACOE in April 2022. The ACOE has never determined that there are jurisdictional waters of the United States on the Copper World site and Hudbay has independently concluded through its own scientific analysis that there are no such waters in the area. In this respect, Hudbay believes the District Court’s decision, together with the 12 May 2022 decision, clarifies the permitting path for Copper World, including the requirements to receive federal permits for the second phase only (ie years 16 to 44 of the project) under existing mining regulations.
PEA completed and PFS underway ahead of potential project sanctioning in 2024
Resources were reported to have expanded materially to 792Mt in the measured category, 381Mt in the indicated category and 262Mt in the inferred category at the time of Hudbay’s PEA at an average grade of 0.40% copper. In April 2022, the company commenced early works at Copper World with initial grading and clearing activities at site – albeit Hudbay is having to contest an ACOE order to stop grading and land clearing on a portion of the site, while also being under a law enforcement investigation by the San Francisco regional office of the US Environmental Protection Agency (EPA) for alleged ‘unauthorized activities’. Nevertheless, main facility engineering has been completed and metallurgical test work is being analysed as part of concentrate leaching trade-off evaluations and Hudbay expects to conclude a pre-feasibility study for Phase I of the Copper World project in Q223. Among other things, this will focus on converting the remaining inferred mineral resources to measured and indicated status and the evaluation of many of the project’s optimisation and upside opportunities. It will then complete a definitive feasibility study as well as receiving all required state and local permits over the next 12 months, while simultaneously evaluating a variety of financing options, including a potential minority joint venture partner, prior to project sanction potentially as early as 2024. As such, Edison is continuing to forecast production from Rosemont/Copper World attributable to WPM in FY27. However, readers should note that any acceleration in the process of being granted federal permits could allow Hudbay earlier access to higher-grade areas of the orebody, especially at Rosemont. In the meantime, it is continuing exploration and technical work at site with seven drill rigs conducting infill drilling to support its feasibility studies.
Antamina
In April 2022, Antamina announced a US$1.6bn investment that will lengthen the mine’s useful life from 2028 to 2036. Currently, the mine is carrying out a third and final ‘public participation’ with residents of the northern Andean region of Ancash, where the mine is located, and is awaiting a response from the local authority, Senace, regarding the company’s request to modify its environmental impact assessment to allow the mine to extend its operating life by eight years. Production and the mine’s operational footprint would remain the same and it hopes to achieve mine extension approval early this year. The mine, which is co-owned by Glencore, BHP, Teck and Mitsubishi Corp, is Peru’s largest, and the world’s second-largest, copper mine.
Pascua-Lama
WPM’s contract with Barrick provided for a completion test that, if unfulfilled by 30 June 2020, would result in WPM being entitled to the return of its upfront cash consideration of US$625m less a credit for any silver delivered up to that date from three other Barrick mines (at which point it would have no further streaming interest in the mine). Given the test was unfulfilled, WPM had the right to an estimated US$252.3m (WPM’s carrying value of Pascua-Lama) repayment from Barrick in FY20. Given the long-term optionality provided by the Pascua-Lama project, however, WPM instead opted not to enforce the repayment of its entitlement and to instead maintain its streaming interest in the project (which was originally expected to deliver an attributable 1.7–12.0Moz silver pa, averaging 5.2Moz Ag pa, to WPM at a cost of US$3.90/oz inflating at 1% per year). A Chilean court ordered Pascua-Lama to close in 2020. However, Barrick is advancing a comprehensive review into Pascua-Lama and has raised the possibility that the orebody could be developed in a different manner, in which case an investment decision on the project could be forthcoming as early as 2024.
Other potential future growth opportunities
In general, WPM expects to be conducting due diligence processes on approximately 10–12 projects at any one time, which it expects to narrow to three to four target projects over approximately 12 months. Most of the opportunities currently being evaluated by WPM are reported to be the precious metal by-product streams of base metal mines, although there are also reported to be some high-margin, purely precious metals mines included as well. In the first instance, WPM would fund any such transactions via the US$2bn available under its revolving credit facility, plus the US$696.1m in cash that it has on its balance sheet (at end-Q422) and, potentially, its US$300m at-the-market equity programme.
While it is difficult, or impossible, to predict potential future stream acquisition targets with any degree of certainty, it is possible to highlight two that may be of interest to WPM in due course for which it already has strong, existing counterparty relationships, being:
■
the platinum group metal by-product stream at Sudbury (operated by Vale); and
■
the 30% of the gold output at Constancia that is not currently subject to any streaming arrangement.

Our improved basic EPS forecast of US$1.15/share for FY23 is 1.7% below the consensus forecast of US$1.17/share (source: Refinitiv, 14 March 2023). In this context, it is worth noting that our gold and silver price forecasts for the remainder of the year are US$1,868/oz and US$21.54/oz, respectively, which are those prevailing at the time of writing.

Valuation
Absolute
WPM is a multi-asset company that has shown a willingness and desire to buy streams in the past to maintain production and maximise shareholder returns. As a result, rather than our customary method of discounting maximum potential dividends over the life of operations back to FY23, in the case of WPM (as with Newmont and Endeavour), we discount forecast cash flows back over four years from the start of FY23 and then apply an ex-growth terminal multiple to forecast cash flows in that year (ie FY26) based on an appropriate discount rate.
Our estimate of WPM’s ‘terminal’ pre-financing cash flow in FY26 is ostensibly unchanged at US$2.57/share (cf US$2.59/share previously), as shown below:
Exhibit 11: WPM cash flow per share and related valuation (US$/share), FY23–26 |
Source: Edison Investment Research. Note: Valuation line assumes ex-growth cash flow per share growth rate of 4.0% pa post-FY26 in nominal terms, which equals the average US rate of CPI inflation since 1972 (ie 0% per annum growth in real terms). |
Note that the negative cash flow that we calculate in FY23 arises almost solely as a result of the assumption that Wheaton will pay Vale US$283m in consideration for the Salobo III expansion over the next 10 months in addition to instalment payments for Santo Domingo, Blackwater, Goose, Curipamba and Marathon. In reality, some (or all) of these could be deferred or delayed. Otherwise, assuming 4% growth in nominal cash flows beyond FY26 (ie 0% growth in real cash flows) and applying a discount rate of 9.0% (being the expected long-term required nominal equity return), our terminal valuation of the company at end-FY26 is US$53.28/share (cf US$53.71/share previously), which, when discounted back to FY23 in combination with intervening cash flows, results in a valuation at the start of FY23 of US$41.11/share (cf US$41.52/share previously), or C$56.49/share (cf C$56.30/share previously). To this should then be added WPM’s end-FY22 net cash position of US$1.54/share (C$2.11/share) to take the total to US$42.65 (or C$58.60) per share. However, this valuation is inherently conservative in that it assumes zero growth in (real) cash flows beyond FY26. This is inconsistent with the gold price, which has risen at a compound average annual growth rate of 7.6% per annum since 1968 and at a simple average annual growth rate of 9.7% per annum (as depicted below).

It is also inconsistent with WPM’s longer-term historical performance, wherein operational cash flows have increased at a compound average annual growth rate of 21.0% pa for the 17 years between FY05 and FY22, while its operational cash flows per share have increased at compound average annual growth rate of 14.1% pa.
Historical
Excluding FY04 (part-year), WPM’s shares have historically traded on an average P/E multiple of 30.4x current year basic underlying EPS, excluding impairments (cf 37.6x Edison or 37.1x Refinitiv consensus FY22e – see Exhibit 14).
Exhibit 13: WPM’s historical current year P/E multiples, 2005–22 |
Source: average share price data Bloomberg, Edison Investment Research calculations |
Applying this 30.4x multiple to our (ostensibly unchanged) EPS forecast of US$1.79 in FY26 (cf US$1.80 previously) implies a potential value per share for WPM of US$54.47 or C$74.85 in that year. However, the graph above suggests that the investing environment post-2017 has been able to support an enhanced WPM multiple relative to earlier years (which we would ascribe to macroeconomic uncertainty creating a supportive environment for precious metals). As such, we believe that a multiple of 37.8x (the average of FY18–22) may still be supported in the event of a return to favour of precious metals and precious metals stocks. In this case, applying a 37.8x earnings multiple to our updated EPS forecast of US$1.15 in FY23 implies a potential value per share for WPM of US$43.48 or C$59.75.
Relative
From a relative perspective, it is notable that WPM is cheaper than its peers on at least 63% (23 out of 36) of the valuation measures observed in Exhibit 14 if Edison estimates are used or 55% (20 out of 36) of the same valuation measures if consensus forecasts are used.

SIGA’s FY22 results highlighted underlying revenue diversification and clinical progression during the year. Results were broadly in line with our expectations. Growth was driven by the material uptick in international orders due to the mpox (monkeypox) outbreak ($71m of $77m orders delivered in FY22), supported by orders from the US Department of Defense (DoD) and BARDA for IV TPOXX. Consistent with prior periods, variability in replenishment of government stockpiles is a key consideration in reported revenues and margins. For FY23 and FY24 we estimate replenishment of government stockpiles will continue to remain a pillar, driven by BARDA deliveries for oral ($225m in total over FY23 and FY24 for expiry replenishment) and IV TPOXX. SIGA remains well-capitalized, with net cash of $98.8m at FY22. We adjust our estimates for the Q422 results and near-term operational visibility (introducing a slower international sales ramp-up) resulting in our valuation adjusting to $17.70/share (from $19.64).
