Reverse circulation drilling extended the White Light mineralisation below 260 vertical metres where it remains open down-plunge.
New results included 2m at 17.7 grams per tonne gold from 198m; 2m at 11.8gpt gold from 227m; and 0.5m at 60.1gpt from 308.5m.
Another hole intersected new zones about 100m to the south of White Light and could reflect parallel lodes.
Results included 4m at 3.3gpt gold from 112m; 3m at 3.4gpt gold from 150m; and 1m at 11.4gpt gold from 179m.
The zones will be followed up.
"These are further excellent drill results from the White Light lode which is continuing to grow," Musgrave managing director Rob Waugh said.
"Importantly, the potential for further untested gold lodes has been identified in this recent drilling with new zones intersected to the south and parallel to the White Light lode.
"It is early days but these new zones have the potential to add further resource ounces at Break of Day. Additional drilling is currently being planned to test these positions."
Further drilling at Starlight returned 2m at 13.7gpt gold from 178m; and 12m at 4.2gpt gold from 5m, extending the near-surface mineralisation to the west.
A maiden resource for the Starlight and White Light lodes is due in late October.
The high-grade Break of Day deposit already has a resource of 868,000 tonnes at 7.2gpt gold for 199,000 ounces.
Regional aircore and RC drilling is underway with the aim of making additional high-grade gold discoveries.
The total resource for the Cue gold project is 613,000oz at 3gpt gold.
Musgrave shares opened 2.8% higher at A55.5c. Friday's close of 54c was the lowest since July, when the stock hit an all-time high of 83c.
