Research: Metals & Mining
Wheaton Precious Metals produced 159,852 gold equivalent ounces (GEOs) in Q322, of which it sold 138,824 GEOs, representing a positive variance of 2.8% and a negative variance of 0.7% relative to our prior estimates, respectively. Its adjusted net earnings were US$1.4m, or 1.6%, above our prior forecast at US$93.9m and the fourth quarterly dividend for the year was maintained at US$0.15/share. In the wake of Q3 results we have revised our forecasts for Q422 and FY22 only very fractionally.

A rising production profile
After producing c 663k GEOs in FY22, WPM now expects its production to increase to an average of 835k pa GEOs in the four years from FY23–26 and then to an average 850k pa GEOs in the period from FY22–31 (implying production of c 900k pa GEOs in the period FY27–31).
US$494.6m (US$1.09/share) in cash and rising
Wheaton had US$492.5m (US$1.09/share) in net cash as at end-Q322. Depending on the timing of investments relating to its newly acquired streams, and the timing of its receipt of US$150m relating to its Yauliyacu stream sale, we estimate that it is possible that it will accumulate as much as US$892.6m in net cash by end-FY22.
Valuation: Trending higher with production
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$55.35 (C$74.87) per share assuming zero subsequent long-term growth in real cash flows and 4% inflation. Stated alternatively, we calculate that WPM’s current share price of C$45.41 discounts a long-term compound annual average growth rate in nominal cash flows per share of just 2.8% pa, which is lower than the average rate of US inflation since 1981. Otherwise, assuming no purchases of additional streams in the foreseeable future (which we think unlikely), we forecast a value per share for WPM of US$34.11, or C$46.13 or £30.20 in FY22, based on a 30.1x historical multiple of contemporary earnings and US$56.43, or C$76.34 or £49.96, in FY26. In the meantime, WPM’s shares are trading on near-term financial ratios that are lower than those of its peers on at least 63% of common valuation measures regardless of whether Edison or consensus forecasts are used. If WPM’s shares were instead to trade at the average level of its peers, then we calculate that its FY22 share price would be US$36.33, or C$49.14 or £32.16 (based on Edison forecasts). Alternatively, if precious metals return to favour, then we believe that a near-term US$43.63 (C$59.02 or £38.63) per share valuation is possible.
Q322 results
Wheaton produced 159,852 GEOs in Q322, of which it sold 138,824 GEOs, representing a positive variance of 2.8% and a negative variance of 0.7% relative to our prior estimates, respectively. Notably strong performances were recorded at Zinkgruvan, Minto and Antamina for at least the second quarter in succession, while gold production at Salobo and silver production at Constancia both outperformed our expectations. In financial terms, the resulting small negative variance in revenues was more than offset by general and administrative expenses that were US$5.9m lower than our prior expectations to result in adjusted net earnings that were US$1.4m, or 1.6%, above our estimate. The fourth quarterly dividend for the year was maintained at US$0.15/share.

From an operational perspective, Sudbury’s operator, Vale, reported that the first phase of the Copper Cliff Complex South Mine Project was opened, including the development of more than 12km of tunnels to reunite the south and north shafts of the mine, which is expected to nearly double ore production at the Copper Cliff Mine (which has historically represented approximately 20% of production attributable to Wheaton from Sudbury). At the same time, production of gold and palladium at Sibanye-Stillwater’s Stillwater mine was adversely affected by floods for the second quarter in succession, which resulted in it being suspended for seven weeks until 29 July (although access to the East Boulder mine and the Columbus metallurgical facility was maintained and both facilities continued to operate throughout the flooding). Meanwhile, production of cobalt at Voisey’s Bay was down 39% relative to Q321, owing to lower grades during the transition from the depleted Ovoid open-pit mine and the ramp-up to full production of the Voisey’s Bay underground mine. However, relative to Q222 production was up 77.2%. As per Vale’s Q322 Performance Report, physical completion of the Voisey’s Bay underground mine extension is now 78% (cf 74% at the end of Q222), with production from the Eastern Deeps anticipated to start in the near future.
Production at WPM’s flagship asset, Salobo in Brazil (also operated by Vale), increased by 29.5% relative to Q222 (cf a 17.2% increase in copper production) as it ramped up after planned and corrective maintenance to the plant’s mill liners (which was the subject of our note, Incorporating Salobo Q222 operating results, published on 27 July). However, sales lagged the recovery in production, with the result that Salobo sold 12,394 (or 28.0%) fewer ounces than it produced during the quarter. In the meantime, according to Vale’s most recent performance report, physical completion of the Salobo III mine expansion was 98% at end-Q322, with the commissioning of the primary crushing circuit, hot commissioning of the conveyor system and the start of wet commissioning of the flotation circuit. The degree of advancement of the project over successive quarters is shown in the table below:

As such, Salobo III is expected to be fully commissioned in the near future followed by a 15-month ramp-up to full capacity.
Ounces produced but not yet delivered
At 11.0% the degree of under-sale of silver during the quarter, relative to production, was in line with the long-run average of 11.9% since Q112 and closely in line with the previous two quarters. By contrast, the 15.7% under-sale of gold relative to production was noticeably above the long-run average of 6.5% (albeit all of the under-sale could be attributable to Salobo).
Exhibit 3: Over/(under) sale of silver and gold as a percentage of production, Q112–Q322 |
Source: Edison Investment Research, WPM. Note: As reported. |
Gold and silver ounces produced but not yet delivered as at 30 September amounted to 67,247oz and 3.6Moz respectively (cf 59,331oz and 3.7Moz at end-Q222). At the period end, we estimate that ounces produced but not yet delivered equated to 2.63 months and 1.77 months of gold and silver production for FY22, respectively (cf 2.34 months and 1.86 months as at end-Q222) and compare with WPM’s target of two to three months of gold and palladium production and two months of silver production.

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$9.8m, non-stock G&A expenses in Q322 were 16.9% below the bottom of the range implied by guidance and below guidance for the seventh quarter in succession.

Given the performance of WPM’s shares during the quarter, stock-based G&A expenses in Q322 were approximately US$3.7m below our prior estimate for the quarter (as shown in Exhibit 6, below):
Exhibit 6: Graph of historical share price move (US$/share) versus quarterly stock-based G&A expenses, Q419–Q222 |
Source: Edison Investment Research (underlying data: Bloomberg and Wheaton Precious Metals) |
The analysis of stock-based G&A expenses over the past 12 quarters relative to the change in WPM’s share price (also in US dollars) continues to exhibit a relatively close Pearson product-moment (correlation) coefficient between the two of 0.78, 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 8.
FY22 and five-year and 10-year guidance
In the light of Q322 results (as well as the Keno Hill and Yauliyacu stream sales), Edison’s short-, medium- and long-term production forecasts relative to Wheaton’s official guidance are now as follows (including the Marathon, Curipamba and Goose streams, but not yet the Fenix stream):

Source: WPM, Edison Investment Research forecasts. Note: *Edison forecasts include Salobo III from FY23e, Rosemont/Copper World from FY27e and Antamina extension from FY28.
WPM’s updated five-year and 10-year guidance is based on standardised pricing assumptions of US$1,800/oz gold, US$24.00/oz silver, US$2,100/oz palladium and US$33.00/lb cobalt. Of note in this context is an implied gold/silver ratio of 75x, which compares with its current ratio of 81.0x and a long-term average of 61.5x (since gold was demonetised in August 1971). Self-evidently, at the standardised prices indicated, our gold equivalent production forecast of 663.0koz gold equivalent (AuE) for FY22e lies well within WPM’s guidance range of 640–680koz AuE.
Otherwise, readers will note that Edison’s medium-term production forecasts are within 1.5% of WPM’s (implied) guidance for the period FY23–26 and within 3.0% of its longer-term guidance for FY22–31 (albeit this estimate necessarily excludes potential future stream acquisitions).
Short-term organic growth opportunities
In the short term, First Majestic is in the process of 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 is investigating installing a 3,000tpd high-intensity grinding mill circuit and an autogenous grinding mill to improve recoveries and reduce operating costs. 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 by two years, to 2024, following the suspension of growth capital activities owing to COVID-19). Similarly, the Voisey’s Bay underground project is in the process of ramping up to full production.
Medium-term growth opportunities
In the medium term, Wheaton has four projects that are progressing on their route to production:
■
Sabina Gold & Silver Corp has announced a formal construction decision for the Goose project and noted that it will be in a position to commence full construction in early 2023 with first production expected in 2025.
■
Artemis Gold announced the commencement of site preparation work at the plant site at its Blackwater project including site clearing, bulk earthworks and sediment/erosion control. Artemis believes the Blackwater plant site will start major construction works in Q123.
■
Generation Mining has delivered the environmental assessment report for its Marathon project to federal and provincial ministers and announced the purchasing of an unused, surplus SAG mill and ball mill ahead of the start of construction late in Q123.
■
Adventus Mining announced an Investment Protection Agreement commitment declaration by the government of Ecuador indicating a significant milestone in the development of the Curipamba Project. In this context, the company is planning for the start of formal construction of the project in Q223.
Longer-term outlook
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, depending on the grade of the material processed, WPM will be required to make a payment to Vale for this expansion, which WPM estimates will be in the range US$550–670m in FY23, in return for which it will be entitled to its full 75% attributable share of expanded gold production. Note, however, that the timing of this payment is dependent upon Salobo III successfully navigating a 90-day completion test, based largely on throughput, the start of which is at Vale’s discretion. The payment also compares 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.
According to Vale’s Q222 performance report, the Salobo III mine expansion is now 98% complete (see Exhibit 2) with start-up now imminent. Once Salobo III has been completed, however, WPM believes reserves and resources 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, although Vale could exercise a right to alter the timing of the incremental payment due for Salobo III.
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.
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 in March 2019, 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 stalled the project. In the meantime, 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.
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, 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 would 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.
Within this context, on 24 May, 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 Army Corps of Engineers (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 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.
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. It expects to advance a pre-feasibility study for Phase I of the Copper World project by the end of this year, which 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 during 2023, 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 a consequence, Edison is now forecasting production from Rosemont/Copper World attributable to WPM in FY27 (cf FY26 previously). 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, 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. The mine, which is co-owned by Glencore, BHP, Teck and Mitsubishi Corp and which is Peru’s largest, and the world’s second-largest, copper mine, anticipates being granted approval for the extension from the country’s environmental authority either later this, or early next, year.
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 (the carrying value of Pascua-Lama in WPM’s accounts) 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, but Barrick has raised the possibility that the orebody could be developed in a different manner, with an investment decision anticipated in 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 the course of c 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$494.6m in cash that it has on its balance sheet (at end-Q322) 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:
■
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 basic EPS forecast of US$1.13/share for FY22 is 4.2% below the consensus forecast of US$1.18/share (source: Refinitiv, 4 November 2022). In this context, it is worth noting that our gold and silver price forecasts for the remainder of the year are now US$1,671/oz and US$20.62/oz, respectively, which are those prevailing at the time of writing (cf US$1,653/oz and US$19.87/oz previously).

Source: Refinitiv, Edison Investment Research. Note: As at 4 November 2022.
We note that our EPS forecast of US$1.47/share for FY23 is based upon expected gold and silver prices of US$1,749/oz and US$24.55/oz, respectively. In the event of precious metals prices remaining at current levels for the whole of FY23, then we estimate that this figure would instead moderate to approximately US$1.19/share.
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 FY22, in the case of WPM (as with Newmont and Endeavour), we discount forecast cash flows back over five years from the start of FY22 and then apply an ex-growth terminal multiple to forecast cash flows in that year (ie FY26) based on an appropriate discount rate.
In this case, in the wake of Q322 results, our estimate of WPM’s ‘terminal’ pre-financing cash flow in FY26 is ostensibly unchanged at US$2.67/share, as shown below:
Exhibit 10: WPM cash flow per share and related valuation (US$/share), FY22–26 |
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). |
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$55.35/share, which, when discounted back to FY22 in combination with intervening cash flows, results in a valuation at the start of FY22 of US$40.24/share, or C$54.43/share (cf US$40.20/share previously). However, this valuation is inherently conservative in that it is based on the assumption of 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 23.2% pa for the 16 years between FY05 and FY21, while its operational cash flows per share have increased at compound average annual growth rate of 15.8% pa.
Stated alternatively, we can say that WPM’s current share price of C$45.41 discounts a long-term compound annual average growth rate in cash flows per share of 2.8%, which is less than the compound average annual increase in US consumer prices from 1981 to the end of 2021.

Historical
Excluding FY04 (part-year), WPM’s shares have historically traded on an average P/E multiple of 30.1x current year basic underlying EPS, excluding impairments (cf 29.7x Edison or 25.8x Refinitiv consensus FY22e – see Exhibit 14).

Applying this 30.1x multiple to our (unchanged) EPS forecast of US$1.88 in FY26 implies a potential value per share for WPM of US$56.43 or C$76.34 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. We would ascribe this observation to macro-economic uncertainty and loose monetary policy combining to create a supportive environment for precious metals prices. As such, we believe that a multiple of 38.6x (the average of FY18–21) may still be supported in the event of a return to favour of precious metals and precious metals stocks. In this case, applying a 38.6x earnings multiple to our unchanged EPS forecast of US$1.47 in FY23 implies a potential value per share for WPM in that year of US$43.63 or C$59.02.
Relative
In the meantime, from a relative perspective, it is notable that WPM is cheaper than its peers on 63% (23 out of 36) of the valuation measures observed in Exhibit 14 if Edison estimates are used or 63% (23 out of 36) of the same valuation measures if consensus forecasts are used.

In conjunction with Arovella Therapeutics’ strategic focus on developing its invariant natural killer T (iNKT) technology, the company has announced it has received a notification of intention from the European Patent Office for the pending patent grant for its cell platform. Management expects the patent to be granted in early 2023, after completing the formalities. Patent applications have also been filed in the United States, Canada, China, Hong Kong and Australia. If granted, the European patent would be valid until 28 February 2039. This should provide intellectual property protection to the company’s clinical and subsequent commercialisation efforts for its iNKT cell platform, the primary focus of Arovella’s R&D programme following the recent strategic review.
