Integra Resources Corp CEO George Salamis said the appointment of Ausenco to lead detailed engineering work on the company’s proposed US$390 million DeLamar gold project in Idaho, USA, was a key milestone in efforts to revive mining at the site.
The former Kinross Gold Corporation-run mine is currently going through National Environmental Protection Act federal permitting.
Integra’s December 2025 feasibility study outlined a 12-year mine life for an openpit oxide heap leach operation producing an average 106,000 oz of gold a year at average all-in sustaining costs of $1480/oz. The company expects to part-fund the project with cash flow from its operating Florida Canyon heap leach operation in Nevada.
Salamis said Ausenco and Integra would advance detailed engineering at DeLamar concurrently with the NEPA process. A final environmental impact statement and record of decision from the US Bureau of Land Management were expected in the second half of 2027.
“As one of the largest and most advanced heap leach projects currently in the NEPA process, DeLamar has the potential to drive long-term economic growth and job creation in southwestern Idaho,” Salamis said.
“The appointment of Ausenco strengthens the company’s position to advance DeLamar as the company progresses through the NEPA process,” Salamis said.
Integra COO Cliff Lafleur said Ausenco had a proven track record of executing similar mandates on openpit projects of DeLamar’s scale.
“Detailed engineering work is already underway and will continue through Q1 2027, with long-lead procurement activities beginning in the second half of this year and continuing through 2027,” he said.
“The detailed engineering, along with the expected receipt of the final EIS and ROD next year, will inform a construction decision for DeLamar.”
Ausenco has retained heap leach engineering, metallurgy and mine planning specialists at Forte, now part of SLR, to work on DeLamar.
