Three Miners Head Into the Quarter That Settles Their 2026 Guidance

Early each year, or late in the one before, a Toronto-listed producer puts a range on the coming year: the gold or copper it expects to pull from its mines. The company is then measured against that range for twelve months, in Canada, under Canadian disclosure rules, wherever the mine happens to sit.

With nine months of 2026 reported, three of the producers Maple covered this week have each moved theirs. Equinox Gold raised its range in August after closing its combination with Orla Mining. B2Gold narrowed its range a day later, after a fire at its Goose mine in Nunavut and a permit delay in Mali. Ivanhoe Mines cut its copper range at Kamoa-Kakula in March, and in October said production was trending toward the lower end of what remained.

Maple's weekday coverage followed each step, from Equinox Gold's largest quarter of the year on October 13 to the ounces B2Gold needs in the second half on October 16. The fourth quarter now decides all three.

A range the company has to answer for

Production guidance is a forecast, and in Canada a forecast comes with obligations attached. National Instrument 51-102, the continuous-disclosure rule for reporting issuers across the country, says a company must not disclose forward-looking information unless it has a reasonable basis for it.

The rule follows the forecast through the year. Section 5.8 requires a company to discuss in its MD&A, the management's discussion and analysis filed with each set of results, any events in the period that are reasonably likely to cause actual results to differ materially from forward-looking information it published for a period not yet complete. It must also describe the difference it expects. A company can meet that duty with an earlier news release, provided the MD&A names it and gives its date. The section carves out disclosure governed by NI 43-101, the separate standard for technical reports on mineral projects.

If a company decides to withdraw a forecast altogether, the same section requires the MD&A to say so and to explain which assumptions are no longer valid. A separate subsection requires the MD&A to compare actual results with any financial forecast or outlook published for the period.

A guidance change is the company's own statement that the basis for its forecast moved. Each change below came with the company's reason attached, and the reasons are where the year's story sits.

Three ranges, three histories

The guidance histories run in different directions, and each began with a dated release.

Equinox moved up because the company became larger. The August release does not give the earlier range, so the size of the raise cannot be read from it. The August 5 range adds Musselwhite in Ontario and Camino Rojo in Mexico for August through December. Equinox said the range equals about 1.1 million ounces on a full twelve months of Orla's production.

B2Gold's cut came at the top of its range, and the company named two causes. On April 17 it announced a fire in parts of the crushing circuit at Goose, its mine in Nunavut, and in August it took 30,000 ounces off the top of Goose's 2026 range. It expected the repairs to be completed in the third quarter. The largest single change, the company said, came from the delayed Menankoto permit at Fekola Regional. The same release said first-half production of 441,411 ounces had exceeded corporate expectations.

Ivanhoe's cut was the largest of the three in proportion, about 22 per cent off the midpoint, and it came with a change of measure. The March 31 release took the midpoint of Kamoa-Kakula's 2026 range from 400,000 to 310,000 tonnes, and cut 2027 by a similar margin. The company attributed the change to updated mine designs with a longer period of development before new areas are stoped, and to development rates about 15 per cent lower than targeted after "adverse geotechnical and hydrological conditions."

The March release also changed the measure, from copper in concentrate to copper in anode or blister. Ivanhoe's July 8 release maintained the March range. By October 8 the top had come down by 20,000 tonnes, and the range was expressed as copper in saleable products.

What the fourth quarter has to carry

The fourth quarter's share follows from two numbers per company: what has been produced so far, and the range. The figures below are the companies' own; the subtraction is the desk's.

For Equinox, the third-quarter total understates the run rate. Musselwhite and Camino Rojo counted for August and September only. Maple's October 13 piece added the July output of the two acquired mines, from the same release, to put the full-quarter equivalent at 261,686 ounces, about 3,000 ounces above what the low end now requires. The company's release the same day said it remained on track for the range. It also said Valentine, in Newfoundland and Labrador, and Greenstone, in Ontario, were positioned for stronger production through the rest of 2026.

At Kamoa-Kakula, the low end asks for slightly more copper than the third quarter delivered. Third-quarter output was about 19 per cent above the second quarter's, and Ivanhoe said higher mining rates across the complex were lifting second-half production. The company's own words on October 8 were "trending towards the lower end." The nine-month figure adds three quarterly releases whose product descriptions differ slightly, so the subtraction is approximate.

B2Gold has not published third-quarter production. Its half-year total leaves about 189,300 ounces a quarter for the low end and about 239,300 for the top. The first quarter produced 237,763 ounces.

How a company says it will miss

A company that expects to fall outside its range has defined ways to say so. It can publish a revised range in a news release, as all three companies did this year. It can discuss the expected difference in the MD&A filed with its results. Or, if the forecast can no longer be supported, it can withdraw the guidance and explain which assumptions failed.

None of the three has done the last of these for 2026. Equinox said on October 13 that it was on track. Ivanhoe said its range "remains" 290,000 to 310,000 tonnes. B2Gold's August 6 range is the last it has published, and its third-quarter results arrive with the MD&A in which section 5.8 asks for that discussion.

Ivanhoe's own history shows how a deep revision travels through the documents. The December 3, 2025 guidance was set after the seismic activity at Kakula in May 2025 and the redesign that followed. The March 31 study then cut both 2026 and 2027, gave the reasons in engineering terms and changed the unit of measure. Each later release restated the current range. A change of that size reached shareholders as a dated document with its causes named.

Where Canada sits in these numbers

Two of the three ranges depend materially on Canadian mines. Equinox's three Canadian operations, Greenstone, Musselwhite and Valentine, produced about 59 per cent of its third-quarter ounces by the desk's division of the October 13 figures, and the company's case for a stronger finish rests on two of them. At B2Gold, the single Canadian asset, Goose, was the mine hit by the April fire, and its narrower range is part of the company's lower ceiling.

Ivanhoe's copper comes from the Democratic Republic of Congo. Its guidance is a Canadian disclosure matter all the same, because the company reports in Canada and files its MD&A under the same instrument.

The documents arrive close together. Ivanhoe reports third-quarter results after the close on November 3, B2Gold after the close on November 4 and Equinox on November 9. Full-year production comes with the fourth-quarter releases early in 2027.

The fourth quarter now has to deliver about 258,500 ounces at Equinox and about 77,900 tonnes of copper at Kamoa-Kakula, and on November 4 B2Gold reports how much of its second half is already in hand.
