Refiled the technical report, effective 19 May 2023, to answer British Columbia Securities Commission comments.

17 Apr 2023resource reserve update● Neutral

The technical report behind that update, effective 1 October 2022 and prepared by Ausenco.
14 Nov 2022resource reserve update● Neutral
Reran the economics to show the effect of the July royalty sale: the company says a $12 million tranche, or the full $60 million at 10% of gold and 30% of silver, makes little difference to the 20-year base case while adding cash. The comparison is against the 2021 assessment's no-royalty figures.
2 Nov 2021resource reserve update● Neutral
The full technical report behind that assessment, effective 9 September 2021, prepared by Ausenco with Tetra Tech, Knight Piesold and Hunter Dickinson personnel as qualified persons.

The completed preliminary economic assessment, with the September figures marginally restated: 15.7% return and $2.3 billion net present value at forecast prices, $4.7 billion at prevailing prices, and 6.4 billion lb of copper over the life of the proposed mine.
9 Sept 2021resource reserve update● NeutralMajor
A preliminary economic assessment put the project as designed in the permit application at a 15.8% return and a $2.3 billion net present value at a 7% discount and forecast long-term prices, rising to $4.8 billion at prices then prevailing, with expansion cases running 90 to 101 years and $5.8-8.5 billion. It values the same mine plan whose federal permit had been refused ten months earlier.
6 Apr 2021resource reserve update● Neutral
The 2021 technical report itself, effective 24 February 2021 - the same resource as before, restated to reflect that the project's federal permit had been refused.
2 Oct 2020resource reserve update▲ Good
Filed the technical report carrying August's rhenium-inclusive resource, which the company says makes Pebble the largest single rhenium resource in the world, ahead of Chile's Chuquicamata at 3.8 million kg.
20 Aug 2020resource reserve update▲ GoodMajor
Added rhenium to the Pebble resource for the first time: 2.6 million kg in the 6.5 billion tonnes measured and indicated at 0.41 ppm, plus 1.6 million kg inferred, on 58,000 assays from 699 holes. With total US rhenium resources around 5 million kg, the company said Pebble raises the domestic total by 84%. Copper, gold, molybdenum and silver figures are unchanged.
27 Feb 2018resource reserve update● NeutralMajor
Filed the technical report behind a slightly larger Pebble resource: 6.456 billion tonnes measured and indicated at 0.40% copper, 0.34 g/t gold, 240 ppm molybdenum and 1.7 g/t silver (57 billion lb copper, 71 million oz gold, 3.4 billion lb molybdenum, 345 million oz silver), plus 4.454 billion tonnes inferred at 0.25% copper. The increase came from a change in the planned processing method that altered assumed metal recoveries, not from new drilling.
