Honey Badger's PC Silver PEA Pegs 22-Year Mine Life

Honey Badger Silver Inc. (TSXV: TUF, OTCQB: HBEIF) released an updated preliminary economic assessment for its 100%-owned PC Silver Mine (Prairie Creek) in the Northwest Territories, reporting a 22-year mine life, average output of 10.7 million ounces of silver equivalent in the first seven years, and after-tax life-of-mine free cash flow of C$4.7 billion at August 31, 2026 spot prices.

Honey Badger Silver Inc. (TSXV: TUF, OTCQB: HBEIF) has put numbers on the asset that has defined it, releasing an updated preliminary economic assessment and mineral resource estimate for the 100%-owned PC Silver Mine — the project long known as Prairie Creek — in Canada's Northwest Territories. The headline figures are large: a 22-year mine life, average production of 10.7 million ounces of silver equivalent annually across the first seven years, and after-tax life-of-mine free cash flow of C$4.7 billion.

The company also reported an all-in sustaining cost of negative US$36 per ounce of silver — a figure that tells you, before anything else, what kind of deposit this is. A negative AISC means the by-product credits from the other metals in the ore more than pay for the entire cost of mining, processing and sustaining capital, leaving silver as a free-carried product on paper. At PC Silver those by-products are zinc, lead and copper, which is why the company frames the asset as silver plus critical minerals rather than a pure precious metals play.

What the assessment actually says

On a pre-tax basis, the PEA shows life-of-mine free cash flow of C$7.3 billion, a net present value of C$3.0 billion at an 8% discount rate and C$4.1 billion at 5%, an internal rate of return of 48% and payback in 2.1 years. After tax, those figures step down to C$4.7 billion of free cash flow, a C$1.8 billion NPV at 8%, C$2.6 billion at 5%, a 38% IRR and payback of 2.4 years. The gap between the pre-tax and after-tax cash flow is roughly C$2.6 billion, which is the implied tax and royalty load over the full 22 years — an illustrative subtraction, not a figure the company broke out.

All amounts are stated in Canadian dollars. The results were disclosed by the company and carried by INN Precious Metals.

A preliminary economic assessment is the earliest of the three standard study tiers under Canadian disclosure rules. It is allowed to include inferred mineral resources, which are the least certain category, and it carries an explicit caveat that there is no certainty the economics will be realised. It is a scoping exercise, not a construction decision. Investors reading a 38% IRR off a PEA should hold it to a different standard than the same number off a feasibility study.

The price deck is doing a lot of the work

The economics above are struck on spot pricing as at August 31, 2026: silver at US$66.41 per ounce, zinc at US$1.84 per pound, lead at US$0.85 per pound, copper at US$6.68 per pound, and a US dollar to Canadian dollar rate of $0.72. That is the single most important disclosure in the release, because a polymetallic PEA is a leveraged bet on its own price deck. Silver above US$66 an ounce is an exceptional environment by any historical standard, and copper near US$6.68 a pound is likewise not a conservative long-run assumption.

The company's own framing acknowledges this. Its release describes the economics as compelling "even at much lower than spot commodity prices," which signals that sensitivity cases at reduced metal prices are part of the study. That is the right instinct, and it is also where serious readers should spend their time. Two questions matter more than the headline NPV:

• How much of the negative US$36 per ounce AISC survives if zinc, lead and copper revert toward more conventional levels? By-product credits are the entire mechanism behind a negative cash cost, so the figure is more sensitive to base metal prices than to silver.
• How does the after-tax NPV behave at, say, a materially lower silver price? A 2.4-year payback has a lot of cushion; a 22-year mine plan built on a single date's spot prices has less.

Also worth noting: the favourable exchange assumption cuts both ways. Revenue is earned in US dollars while capital and operating costs in the Northwest Territories are largely incurred in Canadian dollars, so a weaker Canadian dollar flatters the study and a stronger one compresses it.

Prairie Creek's long history is the other variable

PC Silver is not a greenfield discovery. Prairie Creek is one of the longest-known undeveloped polymetallic deposits in northern Canada, and its history is a history of access, permitting and infrastructure rather than geology. The deposit sits in a remote part of the Northwest Territories where the practical constraints are road access, seasonality, water management and the consultation and permitting framework that governs any development in the region. None of that is solved by a PEA.

That is the honest counterweight to a C$1.8 billion after-tax NPV at an 8% discount. The study establishes that the orebody can support a long-life operation at current metal prices. It does not, by itself, establish a timeline, a financing plan or a permit. For a company of Honey Badger's size, the capital required to build a 22-year mine in that location is the gating item, and the route to it typically runs through a prefeasibility study, a partner or strategic investor, or both.

The updated mineral resource estimate is the quieter but arguably more durable piece of news. Extending mine life to 22 years is a statement about the size and continuity of the resource, and resource growth tends to persist through price cycles in a way that study economics do not.

How the market took it

The US over-the-counter quote, HBEIF, last traded at 0.45, up 1.04% from a prior close of 0.44, with a session range of 0.43 to 0.47, as of the 20:00 GMT close on September 16, 2026. That is a modest move — a penny-scale reaction in a penny-scale stock — and it came against a soft broad tape. The S&P 500 tracker (NYSEARCA: SPY) closed at $754.05, down 0.44%; the Dow 30 fund (NYSEARCA: DIA) fell 1.15% to $515.22; the Nasdaq 100 fund (NASDAQ: QQQ) was effectively flat at $704.72, up 0.03%.

Investors should be careful about reading too much into the OTC line. Honey Badger's primary market is the TSX Venture Exchange under TUF, with additional quotes on the Frankfurt exchange and Tradegate under 1QA. The OTC ticker is typically the thinnest of the group, and liquidity there is not a reliable gauge of how a Canadian junior's home market absorbed a study release.

What to watch from here

Three things will determine whether this PEA becomes a project or stays a document. First, the full sensitivity tables: the price deck at which the after-tax NPV stops working is the number that sets a floor under the equity. Second, capital cost and the funding route — a junior with a multi-billion-dollar NPV and no balance sheet to match it has to dilute, partner or sell, and which of those it chooses matters more to shareholders than the NPV itself. Third, permitting and access milestones in the Northwest Territories, which have historically set the pace at Prairie Creek and will again.

Over the first seven years alone, average output of 10.7 million ounces of silver equivalent implies roughly 74.9 million ounces cumulatively on an illustrative basis — a scale that would make PC Silver a materially significant silver source if it is built. The conditional remains the operative word.

Frequently asked questions

What did Honey Badger Silver announce?

The company released an updated preliminary economic assessment and an updated mineral resource estimate for its 100%-owned PC Silver Mine, also known as Prairie Creek, in the Northwest Territories, Canada. The updated resource extends mine life to 22 years, with average production of 10.7 million ounces of silver equivalent annually over the first seven years.

What are the PEA's key economic results?

Pre-tax, the study shows life-of-mine free cash flow of C$7.3 billion, a C$3.0 billion NPV at an 8% discount rate, C$4.1 billion at 5%, a 48% internal rate of return and 2.1-year payback. After tax, the figures are C$4.7 billion of free cash flow, C$1.8 billion NPV8%, C$2.6 billion NPV5%, a 38% IRR and 2.4-year payback.

How can all-in sustaining cost be negative US$36 an ounce?

A negative AISC occurs when revenue credits from by-product metals exceed the total cost of mining, processing and sustaining capital. At PC Silver those by-products are zinc, lead and copper. The consequence is that the figure is highly sensitive to base metal prices: lower zinc, lead or copper would erode the credit and push the cost per silver ounce back toward positive territory.

What price assumptions were used?

The study uses spot prices as at August 31, 2026: silver at US$66.41 per ounce, zinc at US$1.84 per pound, lead at US$0.85 per pound and copper at US$6.68 per pound, with a US dollar to Canadian dollar rate of $0.72. All study amounts are stated in Canadian dollars. The company says economics remain compelling at materially lower prices.

How is a PEA different from a feasibility study?

A preliminary economic assessment is the earliest of the three standard Canadian study tiers. It may include inferred mineral resources, the least certain resource category, and carries a mandatory caveat that there is no certainty the projected economics will be realised. Prefeasibility and feasibility studies apply tighter engineering, cost and resource-confidence standards before any construction decision.

How did the shares react?

The US over-the-counter quote HBEIF last traded at 0.45, up 1.04% from a prior close of 0.44, with a range of 0.43 to 0.47, as of the 20:00 GMT close on September 16, 2026. The move was modest. Honey Badger's primary market is the TSX Venture Exchange under TUF, with additional quotes in Frankfurt and on Tradegate under 1QA.
