Mine permitting timelines in international context

Canada takes about 27 years to move a mineral discovery into a producing mine — the third-longest of any major mining jurisdiction, behind only Zambia and the United States, and seven years slower than Australia. Yet Canada is the world's number-one destination for exploration spending. The front of the pipeline works; the build end does not.

The gap between finding ore and shipping concentrate is where nation-building in the resource economy actually happens — or fails to. On the discovery side Canada is a global leader: in 2024 it attracted roughly one-fifth of the world's non-ferrous exploration budget and was the single most-targeted country on earth. But S&P Global's 2024 study of mines producing critical minerals found that the average Canadian project needs about 27 years from discovery to first production. Australia — a federation with comparable geology, comparable environmental standards, and a comparable Indigenous-rights regime — does the same job in 20. The bottleneck is not geology or capital. It is permitting, sequential federal–provincial review, and litigation risk in the long middle of the project life-cycle.

How long it takes, by country

S&P Global examined 268 mines producing nine critical minerals (cobalt, copper, gold, lithium, nickel, palladium, platinum, vanadium, and zinc) and measured average years from discovery to first production. Canada sits near the slow end of the table — faster than the United States, but well behind Australia and the lower-friction producers of West Africa and Southeast Asia.

Average years from discovery to production — mines producing critical minerals
Source: S&P Global Market Intelligence, "Mine development times: the US in perspective" (June 2024); country averages as reported July 2024. Figures cover 268 projects across nine critical minerals; jurisdiction averages reflect small project counts (Canada n=11) and should be read as indicative rather than precise. Argentina and Mongolia also rank among the five longest development times, but S&P did not publish point estimates for them, so they are omitted from the chart rather than shown with an invented value.
It is getting worse, not better. S&P's broader all-metals series shows global lead times have roughly tripled since the 1990s. And the contrast with the US is instructive: Canadian and Australian mines may take long, but they reliably reach production. Several flagship US projects (Lithium Nevada, discovered 1978) still have not — which is why investors continue to prefer Canadian and Australian ground despite the wait.

The trend: lead times keep stretching

This is not a fixed cost of doing business — it is a deteriorating one. Across all metals worldwide, the average time from discovery to production has climbed from roughly six years for mines that opened in the 1990s to nearly eighteen years for those that started up in 2020–24. Extended exploration, permitting, and financing each add to the clock.

Source: S&P Global Market Intelligence, "From 6 years to 18 years: the increasing trend of mine lead times" and "Average lead time almost 18 years for mines started in 2020–23" (2024–25). The 2020–24 figure is 17.8 years; mines in feasibility but not yet operating now average ~28 years. This is a global all-metals series and is not directly comparable to the critical-minerals country averages above.

The discovery end is the strength

The permitting verdict lands harder because the discovery end is so strong. Canada is not short of prospects, capital, or geological promise: it remains the world's #1 destination for mineral-exploration spending, drawing roughly a fifth of the global budget. The constraint on Canadian mining is not the front of the pipeline that markets fund, but the regulatory middle that governments control. That capital-attraction story now has its own metric — see Mineral exploration investment (Financing) for the country rankings, provincial breakdown, and the grassroots-discovery caveat.

Findings

Finding 1

27 years is third-worst among major jurisdictions

On S&P Global's critical-minerals measure, only Zambia (~34 years) and the United States (~29) are slower than Canada (~27). Australia, Canada's natural peer, does it in 20. The longest-running global tail — Canada, the US, Argentina, Mongolia, and Zambia — is dominated by Western-style permitting and litigation regimes, not by geology.

Finding 2

The clock is lengthening, not shortening

Global lead times have risen from ~6 years (1990s start-ups) to ~12.7 years (mid-2000s) to ~17.8 years for mines opened in 2020–24 — a roughly threefold increase. Mines still in feasibility today average ~28 years. The drift is structural and points to the permitting-and-financing middle of the life-cycle, not to the drill bit.

Finding 3

The discovery end is a Canadian strength

Canada attracted ~20% of the world's non-ferrous exploration budget in 2024 (~CAD 3.9 B), the top destination globally, and Canadian-headquartered firms accounted for ~38% of worldwide exploration spend. Ontario (~CAD 1.09 B), Quebec (~CAD 0.89 B), and British Columbia (~CAD 0.75 B) lead domestically. The pipeline is full at the front; the constraint is downstream.

Finding 4

The diagnosis is regulatory, and the comparator proves it

S&P attributes Canada's long timelines chiefly to permitting and overlapping federal–provincial review. Australia carries comparable environmental and Indigenous-consultation standards yet finishes seven years sooner — evidence the gap is process design, not standards. This is the explicit rationale behind Canada's critical-minerals strategy and "one project, one review" reforms.

Sources & methodology

Primary sources
Methodology notes
  1. Definitions. "Discovery to production" is the elapsed time from the year a deposit is first discovered to the year of first commercial production. The country chart uses S&P's critical-minerals dataset (268 projects, nine commodities); the trend chart uses S&P's broader all-metals series grouped by start-up cohort.
  2. Comparability. The two S&P series are not directly comparable: jurisdiction averages (critical minerals) run higher than the all-metals global average (~15.5 yrs) because critical-minerals projects skew toward longer-lead deposits. Country averages rest on small samples (Canada n=11) and are indicative. The exploration figures combine two bases — S&P non-ferrous exploration (share of global budget) and NRCan exploration-plus-deposit-appraisal across all commodities (dollar totals) — which is why Canada's ~20% global share and its ~CAD 3.9 B domestic total are reported against different denominators.
  3. Peer set. The meaningful comparators for mining are the major mining jurisdictions (Australia, the US) plus the global average, not the full G7 — Japan, Germany, Italy, France, and the UK are not material mine developers.
