The anomaly was identified in a SKYTEM survey and Juggernaut said the area was believed to have strong potential for both Eskay Creek-style VMS and epithermal mineralisation.
The survey also identified a second anomaly known as Colossus, Juggernaut said, consisting of two lobes each spanning about 20ha.
"These discoveries are located in geologic elephant country and have excellent potential of being one drill hole away from a world class discovery," president and CEO Dan Stuart said.
The company, formerly known as Ardonblue Ventures, is planning IP surveys to better delineate the anomalies and also investigate the porphyry potential at the Inca trend, ahead of an expected 2018 drilling programme.
Highlights from initial chip sampling from the Rockstar zone on the 5.5km Inca trend in December included 1m at 21.7g/t gold, 0.94% copper, 3.42% zinc and 11.55% zinc.
The company raised C$3 million (US$2.4 million) in a placement in 2017 and had working capital of $430,000 at the end of September.
Its shares have ranged between C8c-59c over the past year and rose 12.8% yesterday to 22c.
