1. Ownership and Share Structure Information

The information listed above was updated on the date this article was published and was compiled from information from the company and various other data providers.

On April 15. 2026, Grande Portage Resources Ltd. (GPG:TSX.V; GPTRF:OTCQB; GPB:FSE) released positive results from its Preliminary Economic Assessment (PEA) for its New Amalga Gold Project in Alaska.

This PEA is the first study for the project, using a previously released Mineral Resource Estimate (MRE) by DRW Geological Consultants Ltd. from mid-2024. This year's PEA highlights:

• The Base Case using a US$3,200/oz gold price generates a pre-tax Internal Rate of Return ("IRR") of 69% (after-tax 56%) and a pre-tax net present value ("NPV") at a 5% discount rate of US$979 million (after-tax US$721 million).
• 1.1 year pre-tax payback (1.3 year after-tax) on invested capital at the Base Case gold price.
• Based on price sensitivity analysis at the recent spot gold price of approximately US$5,000/oz, the project returns a pre-tax IRR of 109% (after-tax 91%) and a pre-tax NPV at a 5% discount rate of US$2,128 million (after-tax US$1,557 million) with an after-tax payback period of 0.8 years.
• The PEA production plan incorporates an underground mine with a Base Case production life of seven years, with total production of 1.05 million gold ounces shipped.
• Gold production averages approximately 150,000 ounces shipped per year.
• Average shipped gold grade of 17.6 g/t (after sorting), average mined gold grade of 13.6 g/t (before sorting).
• Pre-Production Capital Cost (CAPEX) of US$254.8M (including US$46.4M contingency).
• Operating Cost (OPEX) of US$272 per production tonne mined, including mining, sorting, overland and seaborne transportation, and minesite G&A.
• All-in Sustaining Cost (AISC) of US$1,408 per ounce payable, inclusive of operating costs, sustaining capital costs, royalty payments, treatment costs, and refining costs.

According to the press release, Grande Portage's CEO, Ian Klassen, commented on the study, saying, "The strong results of the PEA confirm our contention that the project's offsite processing strategy is the optimal development pathway, with high margins, rapid payback, and straightforward engineering combined with a very small environmental footprint. This PEA positions the project well for the future, where detailed design, capital optimization, baseline environmental studies, and permitting can advance with confidence."

The press release also provides conceived mine plans, citing the project as an underground operation with a production potential of 1,150 tonnes per day, with a gold cutoff grade of 7.0 g/t. The mine will be accessed via a 900-meter decline initiated from a surface portal, and the primary method will be longitudinal longhole open stoping, supplemented by a smaller amount of cut-and-fill mining for zones of lower rock mass quality.

Grande Portage Resources Ltd. is a Canadian exploration company that is focused on its 100%-owned, high-grade New Amalga Gold Project in Alaska and developing Alaska's next underground gold mine.

Gold Spikes Amid Peace Deal

Gold investors have had shaky hands, watching inflation rates rise, and metal stocks wobble as the U.S.-Iran War continues. Simultaneous hints of coming peace and military aggression are making the market hard to predict. On April 17, 2026, Josh Chait interviewed unnamed Metals Focus analysts from the Silver Institute for Stockhead.

"Our base case is that the situation will be contained, and that the recent pressure that rising U.S. rate expectations have placed on precious metals prices will be temporary," they said. "Even if the conflict proves prolonged, though, over time, weaker growth, inflationary pressures, and fiscal strain would likely weigh on real yields. Coupled with a resurgence of safe-haven demand as pro-cyclical markets contend with liquidations, this should rekindle interest in both gold and silver." The analysts ended their positive suppositions with a warning: these estimates are based on a healthy physical investment demand, which has shown instability in Q1 2026.

But Matthew Piepenburg of Von Greyerz Gold has more faith in the market. On April 17, he argued, "Gold is rising because over-expanded, and hence diluted, paper currencies are falling. For thousands of years, gold, which is real money, has protected far-sighted investors in such repeated scenarios as a superior store of value to sovereign currencies. The USD is not, and will not be, an exception to this blunt fact."

With President Trump's Friday morning announcement on April 17 that the Strait of Hormuz has been fully reopened, gold stocks have soared today. With oil futures declining, gold has had a more than healthy day. After market open on April 17, Ernest Hoffman of Kitco wrote that, " Gold prices had been rallying since the spot price broke definitively above the US$4,800 per ounce resistance level shortly after 8:20 am Eastern, but the announcements of the reopening of the Strait added rocket fuel to the upward move, driving spot gold to a daily high of US$4,890.78 just five minutes later."

Experts Overweight on Stock

Jeff Valks and Jeff Clark of The Gold Advisor called the release of Grande Portage's PEA a "key de-risking milestone" for the company in an April 16, 2026, report. The two experts note an upside to the company's choice to pursue a direct shipping ore model, writing, "That significantly reduces capital intensity, speeds up permitting, and lowers environmental impact."

Valks and Clark gave the company a 'Buy' rating, stating that ". . . With a defined NPV now in place, the company has a clear valuation anchor — and as it continues to de-risk through permitting, development, and further drilling, we would expect the market to start closing that gap. The combination of strong economics, low capital intensity, and exploration upside makes this a compelling story at current levels. Both Jeff and I are overweight."

On the same day, Chen Lin of What is Chen Buying? What is Chen Selling? wrote about Grande Portage, saying, "GPG.v released the long-awaited PEA, with a NPV of almost CA$1 billion on CA$3,200 gold. Much higher at the current gold price. The company is still working on possibly processing it at a nearby mill for even better economics. GPG performed well in the past year. There is some profit taking on the news, but this should establish the base valuation for the project in the long run."

Applications Underway

In its investor presentation, Grande Portage provided an update on its 2026 plans.

These include waiting for the review of an easement application that the company submitted to enable the development of the initial segment of the mine access road and preparing for the FAST-41.
