The critical mineral antimony plays an essential role in contemporary industry, defense, and the burgeoning field of green technology. It is predominantly utilized as a flame retardant, in the manufacture of lead-acid batteries, and as an alloy strengthener.

Perpetua Resources Corp.'s (PPTA:TSX; PPTA:NASDAQ) Stibnite Gold Project holds the only identified reserve of antimony in the United States.

Material from Stibnite will be used in a pilot plant to produce antimony trisulfide concentrate, a crucial component in munitions and advanced military systems. The company has previously indicated that Stibnite could meet up to 35% of U.S. antimony demand during its initial years of operation.

In company materials, Perpetua Resources continues to highlight the Stibnite Gold Project as both a significant gold asset and a domestic source of antimony, a mineral deemed essential for national defense and industrial applications. The global supply of this mineral is predominantly concentrated in China and Russia. With an estimated 148 million pounds of antimony reserves, Stibnite is positioned as a significant potential contributor to U.S. supply resilience.

The project is situated in Idaho, a region known for its established permitting processes, skilled mining workforce, and dependable infrastructure. According to Perpetua's investor presentation, the project boasts 4.8 million ounces of gold in Proven and Probable reserves and 107 million pounds of recoverable antimony over its mine life.

The growing significance of antimony is linked to its applications in solar panel construction, semiconductor manufacturing, and the development of advanced liquid metal batteries, which are crucial for storing renewable energy.

1From the following analysts' ratings, Street Smart came up with an average rating of Buy / Outperform, with an average target price of US$38.90 / CA$54.07.

Rabi Nizami — National Bank of Canada Capital Markets

Perpetua Resources recently shared several significant updates, including progress on securing a loan from the US Export-Import Bank (EXIM), filing an updated Technical Report Summary (TRS) with revised costs, and releasing their financial results for the fourth quarter of 2025, according to an updated research note on April 8 by Analyst Rabi Nizami for National Bank of Canada Capital Markets.

These developments are viewed positively and are expected to position Perpetua to outperform its peers as it moves closer to obtaining final approval from the EXIM board and making a construction decision within the year, Nizami said.

EXIM's board has informed Congress about a proposed US$2.2 billion senior secured loan facility intended for the development of the Stibnite Gold project. This notification triggers a 25-day review period, concluding around April 24, after which a final decision from the board is anticipated. This step follows earlier indications from the EXIM board minutes reviewed on March 20, suggesting that the loan was progressing towards approval. The confirmation of the notification to Congress reinforces confidence in the final approval of the loan, expected by late April or early May, potentially coinciding with EXIM's conference scheduled for April 29-30.

The proposed loan amount of US$2.2 billion (US$2.7 billion with capitalized interest and fees) exceeds the initial expectations of up to US$2 billion. Together with US$714 million in cash on hand, this funding is sufficient to cover the updated capital expenditure (capex) requirements of US$2.576 billion outlined in the TRS, marking a 15% increase from the previous estimate, the note said.

The capex aligns with our projections, and the updated operational expenditure (opex), which is 6% higher than the previous TRS, is more favorable than our anticipated 15% increase. The project's net present value (NPV) at a 5% discount rate is estimated at US$3.5 billion, slightly above our previous estimate of US$3.4 billion at aligned consensus prices.

In light of these developments, we have revised our financial model to include the anticipated US$2.2 billion loan, a budget of US$328 million for the first half of 2026, and an updated TRS assuming a conservative 5% inflation rate. We also anticipate a US$200 million fundraising effort to serve as a spending buffer. Consequently, our net asset value per share (NAVPS) has been adjusted slightly to CA$54.51 per share, a decrease of 2.3%, based on the long-term price deck of US$3,200 per ounce for gold and US$11 per pound for antimony. However, at current spot prices (US$4,800 per ounce for gold; US$12.4 per pound for antimony), the NAVPS could rise to CA$94 per share, Nizami noted.

Given these factors, the firm raised its target price for Perpetua Resources to CA$55 from CA$50, based on a valuation of 1x NAVPS, up from 0.9x. Currently, Perpetua trades at 0.75x using the long-term price deck and 0.43x at spot prices.

The firm rated the stock Outperform.

Nizami said the firm anticipates a steady re-rating of the NAV over the construction period, with the potential for a more significant re-rating based on EBITDA multiples in the later years of the build, or even an outright M&A acquisition. This is due to the project's large scale, strategic significance to the US military, and untapped exploration potential. A future production multiple of approximately 5x EV/EBITDA for the years 2030-2035 could imply a value exceeding CA$100 per share, the analyst wrote.

Heiko Ihle — H.C. Wainwright & Co.

On February 5, H.C. Wainwright analyst Heiko F. Ihle, CFA, issued a research report on Perpetua maintaining a Buy rating and increasing the price target from US$30 to US$41. This adjustment was largely influenced by an update to the firm's precious metal price forecasts, which now account for the sustained rise in gold spot prices.

According to Factset, that rating was reaffirmed on April 7.

The report also discussed a significant policy development reported by Bloomberg News on February 2, regarding the Trump Administration's plans to initiate Project Vault. This project involves a US$12 billion investment in a strategic stockpile of critical minerals to decrease U.S. reliance on Chinese supplies and mitigate risks from supply disruptions and geopolitical tensions. The analyst pointed out that growing conversations about Europe potentially collaborating with the U.S. to lessen dependence on Chinese supply chains could enhance access to critical minerals in Western markets.

The report underscored the strategic importance of the Stibnite project as a key domestic source of antimony, suggesting that a federally supported stockpile would enhance offtake visibility, reduce financing risks, and boost Perpetua's role as a vital asset in the Western supply chain. H.C. Wainwright revised its precious metal price forecasts effective January 1, 2026, to US$3,750/oz for gold, US$50/oz for silver, and US$5/pound for copper, reflecting macroeconomic factors that have driven up spot prices significantly over the past year. Since February 4, gold has surged 74.5% to US$4,962/ounce, silver has climbed 172.2% to US$87.99/ounce, and copper has increased 33.5% to US$5.94/pound.

The new US$41 price target for Perpetua is derived from a discounted cash flow (DCF) analysis of the Stibnite operations, using a 10.0% discount rate, which Ihle believes aligns with similar assets in comparable jurisdictions with equivalent geopolitical risks. The DCF analysis estimates a combined valuation of US$4.45 billion, or US$34.84 per share. After accounting for pro forma cash and cash equivalents of US$720.0 million, a US$35.0 million valuation for key exploration targets, and subtracting debt, the total valuation reaches US$5.2 billion, or US$40.75 per share, rounded to a price target of US$41.

The report notes that the positive impact of the revised price deck is somewhat offset by a delay in the company's first production to the second half of 2029. Near-term catalysts for Perpetua include advancements in financing and future debt funding, with a decision expected this year. Ihle plans to monitor progress towards a Final Investment Decision, noting that Stibnite is poised to be highly profitable given the current commodity price environment.

Perpetua currently generates no revenue and reported a diluted EPS of (US$0.22) in 2024, with estimates of (US$0.38) for 2025 and (US$0.16) for 2026. Key risks include commodity price fluctuations, operational and technical challenges, financial uncertainties, and political risks. As of February 4, 2026, Perpetua's shares traded at US$28.47, suggesting a potential 44% upside to the US$41 target, with an enterprise value of approximately US$2.75 billion, a market capitalization of about US$3.47 billion, and pro forma cash of US$720 million following a recent equity raise. The 52-week trading range was US$7.81 to US$35.97.

Nick Giles — B. Riley Securities

On March 31, Perpetua highlighted its fourth quarter financial results for 2025, a Congressional notice by the EXIM Board regarding US$2.7 billion financing (including capitalized interest and fees of US$500 million), and updated economic assessments of the Stibnite project, according to an April 1 research note by Analyst Nick Giles for B. Riley Securities.

The stock saw an 11% increase in its value, outperforming the R2K's decline of 1.5%. Looking forward, several key events are expected to further boost Perpetua's performance. Firstly, the EXIM board's 25-day Congressional review is underway, with final approval of the US$2.2 billion funding anticipated soon, setting the stage for a construction decision in the second half of 2026. Secondly, updates to the Technical Report Summary have refined metal price assumptions and cost estimates, reflecting current inflation and potential tariff impacts, making them more realistic, Giles wrote.

The updated project economics show a net present value (NPV) of 5% at US$3.5 billion and an internal rate of return (IRR) of 23.5%, significantly improved from previous estimates. This shift from funding and permitting risks to a focus on execution indicates that Perpetua is ready to begin construction at Stibnite and engage in downstream antimony off-take agreements later this year. The stock currently trades at a spot price-to-net asset value (P/NAV) of 0.46x, and 0.69x based on the firm's metal price deck.

Key upcoming catalysts include securing the EXIM loan, advancing engineering and procurement for construction readiness, and initiating construction in the second half of 2026. Additionally, Perpetua is exploring potential tungsten opportunities at the site, given its historical production and the limited domestic supply, the analyst reported.

The EXIM Board has progressed to notifying Congress of the proposed US$2.7 billion senior secured long-term loan under the Make More in America program, initiating a 25-day review period. This is the final step before the board's final approval vote, with funding expected to close in the second half of 2026. The US$2.2 billion in funding, along with US$773 million in existing cash and equivalents, fully covers the initial US$2.6 billion capital required for Stibnite's construction, avoiding any potential equity dilution.

The updated Technical Report outlines an NPV5% of US$3.5 billion and a 23.5% IRR, using a base case gold price of US$3,250/oz, with antimony at US$10/pound and silver at $40/ounce. This represents a substantial increase from previous estimates, reflecting updated capital and operating costs due to inflation, geopolitical uncertainties, and potential tariffs. Contracts with key suppliers like Hatch, ATCO, and Idaho Power anchor these cost estimates.

In summary, the firm maintained a US$40 price target and Buy rating for PPTA, based on a detailed NAV analysis of the Stibnite Gold Project. The valuation incorporates updated production assumptions and a long-term gold price of $3,000/oz, applying a 0.90x P/NAV multiple to reach an estimated NAV of US$3.2 billion, while also accounting for potential exploration upside.

Brian Quast — BMO Capital Markets

In light of recent developments, the financial outlook for the Stibnite Gold Project has undergone significant revisions, wrote Analyst Brian Quast in an April 1 research note for BMO Capital Markets.

The initial capital estimate for the project has increased by approximately 15% to US$2.576 billion from the previous US$2.215 billion, and the life-of-mine all-in sustaining costs (AISC) have risen by about 10% to US$833 per ounce from US$756 per ounce, primarily due to inflationary pressures, noted Quast.

In response, the U.S. Export-Import Bank has demonstrated strong federal support for the project by unanimously deciding to notify Congress of a proposed US$2.7 billion senior secured long-term loan, an increase from the earlier guidance of up to US$2 billion. This move underscores the government's commitment to the project's success without necessitating shareholder dilution, despite the challenges of construction, the report said.

The Export-Import Bank's notification to Congress involves a direct loan of approximately US$2.2 billion with the remainder allocated for capitalized interest and fees. This notification commences a 25-day review period and represents the final procedural step before the EXIM Board's vote on final approval, expected shortly after this period concludes. The funding is contingent upon the finalization of definitive loan documents and the fulfillment of all closing and drawdown conditions, anticipated in the second half of 2026.

Perpetua Resources has also updated its Technical Report Summary, reflecting more conservative financial estimates due to inflation and detailed cost and technical data from signed contracts with companies such as Hatch and ATCO, as well as ongoing negotiations, according to Quast. This has led to the revised capital and AISC estimates. The company has incorporated additional conservatism into its financial modeling to account for the current challenging mining cost environment.

On the operational front, management has indicated that restrictions from voluntary stipulations with plaintiffs regarding early works construction activities are set to expire in April. This clearance will enable Perpetua to proceed with early works and prepare for full-scale construction slated for the latter half of 2026. While the timeline for first production remains targeted for 2029, the expected commencement has been adjusted to the end of that year, slightly later than initially planned.

Quast said the firm's valuation of Perpetua Resources remains optimistic with an Outperform rating on the stock and a target price of CA$47 based on a 1.4x price-to-net present value (P/NPV) multiple, using a 5% discount rate and BMO's metal price assumptions. Currently, Perpetua trades at 1.2x P/NPV, compared to an average of 0.9x among peer project developers.

In an upside scenario, where exploration success on Perpetua's land package leads to an extended mine life or higher ore grades, the potential value could soar to US$65, highlighting the significant growth prospects of the Stibnite Gold Project, Quast wrote.

Mike Kozak — Cantor Fitzgerald

The U.S. Export-Import Bank (EXIM) is progressing with a significant financial proposal, advancing a US$2.7 billion loan to support the development of Perpetua Resources' Stibnite gold-antimony project in Idaho, Analyst Mike Kozak of Cantor Fitzgerald wrote in a March 31 note.

This development is positively received as it triggers a 25-day notice period to Congress, after which the EXIM Board is expected to vote on final approval. The completion of this senior secured long-term loan, with undisclosed interest rate and tenor, is anticipated in the second half of 2026, he said.

Key details of the EXIM loan reveal an increase from the previously anticipated US$2 billion to US$2.7 billion. This loan includes US$2.2 billion directly allocated for project construction and an additional US$0.5 billion to cover capitalized interest and fees, ensuring full funding for the Stibnite project through to production.

Concurrently with the loan announcement, Perpetua Resources updated the economic projections for the Stibnite project, the analyst noted. These revisions reflect more realistic capital expenditures (CAPEX), operational expenditures (OPEX), and metal prices as of the end of the fourth quarter of 2025. The updated figures include an initial CAPEX of US$2.6 billion (previously US$2.2 billion), an all-in sustaining cost (AISC) net of by-products at US$833 per ounce (previously US$756 per ounce), and an after-tax net present value (NPV) at 5% of $5 billion assuming a gold price of US$4,000 per ounce (previously $4.1 billion at US$3,100 per ounce). Using a gold price of US$4,000 per ounce and adjusting for a 7.5% discount rate, the revised capital and operating costs result in an NPV of US$3.8 billion, compared to the previous US$4.4 billion.

In light of the advancing EXIM loan, Cantor Fitzgerald's target multiple has been adjusted from 0.9x to 1x net asset value per share (NAVPS) at a 7.5% discount rate, offsetting the reduction in project NPV caused by the increased capital and operating costs. We reiterate our Buy rating on Perpetua and continue to view the company as a highly likely candidate for a takeover.

Cantor Fitzgerald rates the stock a Buy with a US$49 per share target, a 46% return from when the note was written.

Josh Wolfson — RBC Capital Markets

Perpetua recently announced significant progress regarding its US$2.7 billion U.S. Export-Import Bank (EXIM) loan aimed at funding the development of the Stibnite project, Analyst Josh Wolfson noted in an update for RBC Capital Markets, also on March 31.

Alongside this, the company also provided an update on the project's economics. The developments are viewed as slightly positive, enhancing the likelihood of securing project funding and advancing construction in the second half of 2026. The updated economic projections reflect adjustments for inflation and higher metal price assumptions, with capital costs now estimated at US$2.6 billion, marking a 15% increase from 2025, and all-in sustaining costs (AISC) revised to US$650 per ounce, an 11% rise from the previous year. Under the base case scenario using metal prices of US$3,250 per ounce for gold, $US10 per pound for antimony, and US$40 per ounce for silver, the revised project estimates show a net present value (NPV) at a 5% discount rate of US$3.5 billion and an internal rate of return (IRR) of 23.5%.

In terms of funding, the EXIM Bank's board has unanimously decided to notify Congress of the proposed US$2.7 billion loan, which excludes capitalized interest and fees, setting off a 25-day notice period before the board votes on final approval, Wolfson said. A conclusive vote is expected shortly after this period, with the potential closing of the financing slated for the latter half of 2026. With the pending EXIM debt funding combined with US$714 million in cash, PPTA is well-positioned to fully fund the revised initial capital expenditure of US$2.6 billion, potentially leading to a positive final investment decision in 2026.

Disclosures for National Bank of Canada Capital Markets, Perpetua Resources Corp., April 8, 2026:

RISKS: Commodity Price Risk. Once producing, Perpetua would have the majority of its revenues tied to the sale of gold. Any decline in the price of gold may materially affect the company’s development and mining activities in the future. Other commodity price risks include antimony, although at a much lower significance vs. gold. Regulation Risk. The mining, processing, development and mineral exploration activities of Perpetua are subject to various laws governing prospecting, development, production, taxes, labour standards and occupational health, mine safety, toxic substances, land use, water use, land claim of local people and other matters. Permitting/Environmental Risk. The Stibnite project is subject to environmental regulation in the state of Idaho as well as regulations at a U.S. Federal level. These regulations require the project to operate within certain levels to maintain permits and advance the project. These regulations mandate the maintenance of air and water quality standards and land reclamation. The site requires a substantial cleanup of prior mining activities and an extensive 25-year reclamation plan. As the project is yet to achieve a fully permitted status, delays could occur in the granting of the final permits and or outright refusal to grant one or more of the final permits without more work carried out by the company to meet additional requirements and/or address new concerns raised by the permitting issuing government departments. Financial Risk. We assume that financing required to fund the development of Stibnite should come in the form of mostly debt, with the bulk of it assumed to be granted by EXIM at competitive interest rates, which is not guaranteed to be achieved on both the scale granted and the interest rate. Assuming this level of debt is granted, a portion of Perpetua’s future cash flows will be required to service this debt.

Paired Trade Disclaimer From time to time, B. Riley Securities, Inc. Research Analysts will offer short-term trading ideas, including identifying a paired trade. In a paired trade, an investor buys the securities of one company and sells the securities of another company. The idea to buy the securities of one company and sell the securities of the other company is based on the expected short-term price move or relative value between the two companies mentioned in the paired trade, not between the companies and any other companies. In contrast, the recommendations in a Research Analyst’s published report reflect the Research Analyst’s views on a company over the long term (i.e., the next 12 months) relative to other companies covered by the Research Analyst. The trade idea in a paired trade is unrelated to the Research Analyst’s long-term view of the companies as expressed in the Research Analyst’s most recently published research report. A paired trade idea to sell a company that is rated as Neutral or higher, or to buy a security that is rated Neutral or lower, is not inconsistent because the call to sell or buy the company is relative to the other company mentioned in the paired trade over the short term; it is not a long-term view relative to other companies covered by the Research Analyst.

Definitions of recommendations BUY: The stock is attractively priced relative to the company’s fundamentals and we expect it to appreciate significantly from the current price over the next 6 to 12 months. BUY (Speculative): The stock is attractively priced relative to the company’s fundamentals, however investment in the security carries a higher degree of risk. HOLD: The stock is fairly valued, lacks a near term catalyst, or its execution risk is such that we expect it to trade within a narrow range of the current price in the next 6 to 12 months. The longer term fundamental value of the company may be materially higher, but certain milestones/catalysts have yet to be fully realized. SELL: The stock is overpriced relative to the company’s fundamentals, and we expect it to decline from the current price over the next 6 to 12 months. TENDER: We believe the offer price by the acquirer is fair and thus recommend investors tender their shares to the offer.

Equity valuation and risks. For valuation methods used to determine, and risks that may impede achievement of, price targets for covered companies, please see the most recent company-specific research report at www.rbcinsightresearch.com or send a request to RBC Capital Markets Research Publishing, P.O. Box 50, 200 Bay Street, Royal Bank Plaza, 29th Floor, South Tower, Toronto, Ontario M5J 2W7. Perpetua Resources Corp. Valuation Our US$42.00 price target reflects our 1.0x NAV target multiple to our Stibnite NPV8% estimate, inline with our average developer target multiple (~1.0x) reflecting completed permitting, project financing, and the tier 1 jurisdiction in Idaho. The implied return to our price target supports our Outperform, Speculative Risk rating. We have assigned a Speculative Risk qualifier to reflect the early-stage nature of the project and construction risk ahead. Risks to rating and price target • Permitting and Legal Risk: Despite securing the final ROD from the US Forest Service, legal challenges under NEPA, the Clean Water Act, or ESA could delay construction or trigger additional requirements. Such setbacks could extend timelines, increase costs, or undermine investor confidence in the project. • Financing Risk: While PPTA has a DoD off-take agreement and raised $475m for 2025, $200-250m in royalty sales and $2bn in EXIM bank debt remain critical. Unsecured funding or higher-than-expected costs could delay timelines or negatively impact valuation. • Technical and Execution Risk: Recovering refractory ore at Stibnite hinges on effective POX circuit operation. Construction delays, recovery shortfalls, or cost overruns could threaten project economics and stall payback periods, increasing financial and operational risks. • Commodity Price Risk: Gold and antimony price volatility significantly impacts project feasibility. Market sensitivity to Chinese antimony supply and unstable industrial demand could erode margins, challenging cash flow and financing opportunities. • Antimony Refining: With no US-based refining for antimony concentrate, domestic capacity must be established alongside Stibnite’s construction. Delays in refining agreements or capacity could harm payability and weaken overall project economics. • Jurisdictional and ESG Risk: Idaho is favorable for mining, but legacy contamination at Stibnite raises ESG concerns. Environmental scrutiny, public opposition, or unmet restoration targets could escalate costs, damage reputations, or delay development.
