Why Hercules Metals Is Drilling the Kilometre Between Two Discoveries

A single hole at the Southern Flats zone in western Idaho cut 286.52 metres of copper porphyry mineralisation, Hercules Metals Corp. (TSXV: BIG) reported on 30 September 2026. The company has never published a mineral resource estimate.

Hole HER-26-01 graded 0.58 per cent copper equivalent over that interval, and 0.80 per cent copper equivalent over a 65.54-metre core of it, according to the release.

The geometry matters more than the grade here. The company says 3D modelling suggests Southern Flats may be an approximate one-kilometre southern extension of Leviathan, the porphyry system it discovered in 2023, and that a roughly one-kilometre gap in drilling separates the two. Holes now turning are aimed into that gap.

Hercules trades on the TSX Venture Exchange and in Frankfurt under the symbol C0X, WKN A3DRWX, ISIN CA4270861038, per Deutsche Börse's listing record. The shares closed at C$1.22 on 30 September 2026, down 5.4 per cent from the previous close of C$1.29, on 655,531 shares on the venture exchange and 1,011,938 across all Canadian venues, per TMX Money exchange data read after the close. Those are 15-minute delayed secondary market figures and are not verified against SEDAR+ filings.

A 286-metre intercept is a drill result, not a deposit

The release is careful about this, and the number is large enough that the caution matters.

Hercules states that "the intervals reported represent drill intercepts and insufficient data are available at this time to state the true thickness of the mineralized intervals." A drill hole passes through rock at whatever angle it was collared at. If it happens to run along the length of a mineralised body rather than across it, the metres reported are longer than the body is thick. Until enough holes exist to model the shape, nobody knows which of those two things happened, and the company is saying so.

The sampling is documented. Samples were prepared at MSA Labs in Elko, Nevada and analysed at MSA Labs in Langley, British Columbia, both ISO 17025 and ISO 9001 certified, with blind certified reference materials and blanks inserted by the company. Dillon Hume, P.Geo., vice-president exploration, is the qualified person for the release. George Ogilvie is president and chief executive; Chris Paul, senior vice-president exploration, is quoted saying that systematic exploration has produced two significant porphyry copper discoveries at Hercules since 2023. Those titles are as given in the 30 September 2026 release.

The copper-equivalent figure is four metals and one assumption

Copper equivalent is a convenience. It takes the other metals in the rock, converts them into the copper they would be worth at chosen prices, and adds them to the copper grade so a single number can be quoted.

Hercules sets it out: CuEq % = Cu % + (0.000512 × Mo ppm) + (0.010591 × Ag g/t) + (0.902879 × Au g/t), using three-year trailing average prices of US$4.20 a pound for copper, US$2,600 an ounce for gold, US$30.50 an ounce for silver and US$21.50 a pound for molybdenum, and assuming 80 per cent metallurgical recovery.

Two things follow. First, the copper equivalent moves with the price deck, and a three-year trailing copper price of US$4.20 a pound is well below the US$6.57 a pound copper traded at on 30 September 2026, per Trading Economics market data. A higher copper price lowers the equivalent contribution of the other metals, so the conversion is conservative on that input rather than flattering.

Second, the 80 per cent recovery is an assumption, not a test result. The release reports no metallurgical work. The plain copper grade, which needs no assumption at all, is 0.43 per cent over the 286.52 metres and 0.61 per cent over the 65.54-metre core of it.

Faraday Copper shows what a counted pound is priced at

The comparison copper juniors are usually put through is dollars of market value per pound of contained copper. Running it here demonstrates why it cannot be run here.

Faraday Copper Corp. (TSX: FDY) is a reasonable reference: a Canadian-listed company advancing a copper porphyry in the southwestern United States, at the stage Hercules would reach if the drilling works. Its Copper Creek estimate, effective 9 February 2023, reports 421.9 million tonnes at 0.45 per cent copper in the measured and indicated categories, containing 4,203.8 million pounds, plus 83.6 million tonnes at 0.34 per cent copper inferred, containing 628.2 million pounds.

The basis and its limits, stated together: these are market capitalisations from TMX Money on 30 September 2026, not enterprise values, because cash and debt for neither company were verified against filed financial statements. Faraday's resource is three and a half years old and precedes drilling done since. The two projects differ in geology, depth and metallurgy. And the bottom row is the point rather than a gap in the table. Faraday's number exists because somebody counted the pounds and a qualified person signed for them. Hercules has intercepts, and an intercept is not a tonnage.

That asymmetry is what a person comparing the two market values is actually looking at. About C$407 million is being paid for a drilling programme and a geological model. About C$1.6 billion is being paid for a counted resource with an economic study attached. Those are different products, and the ratio between them is not evidence about either one.

Barrick appears twice in this story, and never as a buyer of the company

The relationship is easy to over-read, so here are the terms.

In August 2025 Hercules closed an option agreement with a Barrick subsidiary over the Olympus Claims, more than 74,000 acres of unpatented mining claims around Leviathan, which if fully exercised would take the company's land position past 100,000 acres. Hercules issued 2,681,427 common shares at a deemed price of C$0.74587136, set on a five-day volume-weighted average, and agreed to reimburse annual claim maintenance estimated at about US$740,000 a year. Hercules can earn a 100 per cent interest in the claims.

Separately, Barrick holds a strategic equity position, described on the company's investor page as a C$25 million investment, and holds a participation right to maintain its pro-rata ownership. That right was recorded in the 6 May 2026 financing, in which Hercules raised C$31.5 million by issuing 53,353,000 common shares at C$0.59, comprising 36,353,000 shares under a listed issuer financing exemption offering and 17,000,000 under a concurrent placement, with BMO Capital Markets and SCP Resource Finance as joint bookrunners.

Neither arrangement is an acquisition, a joint venture on the core discovery or an offtake. A major's money and land support the programme; they do not price it.

On the share count, the exchange lists 333,406,487 common shares issued and outstanding and 350,156,487 shares across all classes as at 30 September 2026, giving a market value of C$406.8 million on the listed shares and C$427.2 million across all classes. The company's own investor page, current to 10 September 2026, shows 350.4 million issued and outstanding and 367.1 million fully diluted, including 14.0 million options and 2.67 million restricted share units. The two counts are on different bases and the difference is not reconciled in either document.

The kilometre of undrilled ground is the next measurable thing

Three holes are in progress or awaiting results, according to the 30 September release: assays are pending for HER-26-04, and HER-26-05 and HER-26-06 are drilling. The company says drilling will keep prioritising expansion at Leviathan.

If the intervening kilometre returns continuous mineralisation, Southern Flats and Leviathan stop being two discoveries and become one system with a length that can be modelled, and a resource estimate becomes a document somebody can start. If it returns barren rock, Hercules has two separate zones and a longer road to the same place. Neither outcome is knowable from a single 286.52-metre intercept, and the company has not claimed it is.

Most exploration projects never become mines. What Hercules has is a large, well-documented set of intercepts in a jurisdiction that permits mining, a land package assembled with a major's help, and C$31.5 million raised in May to keep drilling. What it does not have is the one document that would let anyone price it the way copper juniors are usually priced. Until that document exists, the C$407 million is a valuation of drilling, and it will keep being argued about on that basis.
