The gold torcs, believed to date back around 3,000 years, were uncovered during a metal detecting rally on land near Blackford and Harker.
The site is close to an area being considered for National Grid’s proposed Cross Border Connection project.
A Cumberland Council spokesperson said: “Our Historic Environment Service is aware of the finds made at the metal detecting rally near Blackford.
“We are awaiting further details on the exact locations and what was recovered.
“Statutory designation to protect archaeological sites is undertaken by Historic England.
“Requests can be made to them to assess any sites – this is open to all.”
The torcs were discovered during a four-day rally involving around 100 detectorists.
Participants also unearthed a Roman coin hoard, a medieval coin hoard and a Bronze Age axe head.
Campaign group North Carlisle Against Pylons and Substations says the discoveries highlight the historical importance of the area and strengthen calls for protection.
Spokesperson Allan Harty said finding three torcs together was “incredibly significant”.
“To find one torc is rare, but to find three together is incredibly significant,” he said. “It just shows how important this area may have been historically.”
The artefacts have been reported to the Finds Liaison Officer and will be assessed by experts.
Campaigners are urging Historic England to investigate the site and are calling for National Grid’s proposed substation to be located elsewhere.
National Grid has said any verified archaeological discoveries would be carefully considered as part of the project’s appraisal process and that it works closely with heritage specialists, local authorities and Historic England when developing its proposals.
