Among the highlights, Pretium reported 1m at 58.7g/t within 90.21m at 1.71g/t gold.
The holes were drilled east from Valley of the Kings underground development and confirmed mineralisation continued to beneath the Flow Dome Zone, with features also suggesting increased proximity to porphyry style mineralisation beneath this zone.
Pretium said it would use the results to plan future drilling to focus on Valley of the Kings resource expansion, and would start a follow-up surface geophysical programme.
It said a regional, grass roots exploration drilling programme was expected to begin next month to follow up on "the identification of several distinct areas that have the potential to host mineralised zones similar to the Valley of the Kings and Eskay Creek deposits".
Brucejack is ramping up and after overcoming some setbacks, the company said last month it was "confident" it would deliver on its first half guidance of 150,000-200,000 ounces at an all-in sustaining cost of US$700-$900/oz.
Pretium had working capital of $63.4 million at the end of March, excluding the current portion of long-term debt, up from $40.6 million at the end of 2017.
It is aiming to achieve steady-state production in mid-to-late 2018.
Pretium shares closed up 4.88% to C$9.88 yesterday but remain down 31.1% so far this year, capitalising it at $1.8 billion.
