History
Amarc, a British Columbia copper-gold explorer, lost its first partner, won Freeport and Boliden to fund drilling, then found AuRORA, while Boliden's 2026 stop at 60% leaves it funding 40% of DUKE.
2018-2020: Alone after Hudbay
Amarc is a British Columbia copper-gold explorer with three districts: IKE, JOY and DUKE. Its model is to assemble large areas of ground and have bigger companies pay for the drilling in return for a share of the project. In June 2018 it reported six new holes (3,060 metres) at DUKE. With the two 2017 discovery holes, they outlined copper mineralisation 400 metres by 600 metres under only 4 to 18 metres of glacial till, open in all directions. Seven of eight holes hit, with best results of 0.34% and 0.37% copper-equivalent. These were bulk-tonnage grades, meaning modest grades over large volumes, not high grade. DK18004, drilled a kilometre north, returned only 0.30% over 93 metres.
In January 2019 Hudbay gave up its options on both IKE and JOY. Hudbay and Amarc had put C$5.55 million into JOY over two years, and that work stood, but Amarc was left alone on all three districts and looking for partners. In December 2019 Amarc bought Gold Fields' remaining 51% of the PINE property for 5,000,000 shares, plus 2,000,000 more only if certain spending levels are reached. After buying Cascadero Copper's 49% the year before, it held 100% of 323 square kilometres at the core of JOY. Gold Fields kept royalties over the ground.
2021-2023: Freeport and Boliden arrive
In May 2021 Freeport-McMoRan's Canadian arm signed an earn-in on JOY, able to take up to 70% through staged investment, with Amarc as operator. First assays under Freeport, in March 2022, expanded the PINE deposit with 101.9 metres of 0.56% copper-equivalent. The first hole ever drilled at the TWINS target found porphyry-type mineralisation: 63 metres of 0.18% copper-equivalent including 39 metres of 0.22%. Freeport spent about C$14 million at JOY in 2022. The 2022 programme (37 holes, 15,427 metres) stretched PINE to more than 1,700 metres of strike and made a new discovery at Canyon, with 96 metres of 0.51% inside 296 metres of 0.39%. Freeport had put in about C$20 million across two years.
In November 2022 Boliden signed an earn-in on DUKE, able to reach 70% by staging C$90 million of spending. Its first holes in early 2023 returned bulk-tonnage grades: 542 metres of 0.33% and then 309 metres of 0.42%, and a third rig was added. Corporate funding was harder. In December 2023 Amarc raised C$2.77 million by issuing 25,000,000 shares, at C$0.13 for flow-through shares and C$0.08 for units, and a new insider emerged. The record also shows a C$1 million director loan, extended twice. Shares on issue rose from 186,602,894 at the end of 2023 to 211,702,894 a year later. The 2023 work at JOY was surveys only, with no drilling.
2024-2025: The AuRORA discovery
In late 2024 Amarc drilled the never-drilled Northwest Gossan target at JOY. The first hole, JP24057, returned 82 metres of 1.08% copper-equivalent. Step-outs followed, including 162 metres of 1.90% and, in the best hole, 132 metres of 1.71% including 90 metres of 2.26%. Not every hole matched: some returned 0.56% or 0.88%. The 2024 programme ended four sections short because the crew camp closed for the season. A new porphyry discovery was also made at Twins.
Amarc also drilled IKE, which it owns outright and funds itself. Nine holes in the Greater Empress area, 6 kilometres north, returned 181 metres of 0.46% including 60 metres of 0.90%, but no partner pays for that work.
In May 2025 Freeport completed its C$35 million Stage 1 and earned 60% of JOY. In September it elected Stage 2, a further C$75 million over five years, and became operator, with Amarc retained as contractor. The JOY titles moved into Aurora Minerals Ltd, held 60% by Freeport and 40% by Amarc. Step-outs through late 2025 pushed AuRORA north and east.
2026: Mapping the new position
In January 2026 the last 12 of 23 expansion holes showed AuRORA covering 1.4 kilometres by 0.8 kilometres, roughly triple its 2024 footprint and still open to the north, east, south and southwest, with 45 holes and 17,586 metres drilled over 2024-25. In February Amarc reported TWINS, 17 kilometres southeast, as a third porphyry system: four holes over five years, the best 300 metres at 0.51 g/t gold and 0.23% copper from 819 metres. Its grades are far below AuRORA's and it starts deep, and the company said more drilling is needed.
In April 2026 Boliden completed C$30 million of spending and earned 60% of DUKE, then declined to take 70% by investing a further C$60 million. DUKE became a 60:40 joint venture from 1 April, so Amarc must fund 40% of each programme or be diluted, ending the free carry it had had since 2022. Amarc remains operator and a 2026 programme is being planned. No property had a mineral resource estimate, AuRORA had none, IKE had no partner, and shares on issue stood at 225,377,364.
