The company reported a number of significant intersections from the prospect in the Murchison Gold Province, including the 3.25 metres at 18.5 g/t standout that was returned from 107 metres.
Other highlights from the campaign included: 5 metres at 3.6 g/t from 24 metres, 6 metres at 4.0 g/t from 37 metres; and 11 metres at 4.9 g/t from 42 metres.
Thundelarra has previously announced a number of other intersections and these include a highlight 2.4 metres at 66.5 g/t from 263.4 metres.
Western Australia-based Thundelarra drilled 3,713 metres over 17 holes in its latest Crown Prince campaign to produce the best gradings it has seen at the WA project.
Thundelarra said gold mineralisation was encountered in 13 of the holes.
Six holes or 1,153 metres were diamond drill tails while 11 were reverse circulation (RC) holes, with an extra six RC collars, for another 2,560 metres.
Results augur well for future exploration at the prospect.
The company said: “This program at Crown Prince continued to deliver outstanding results, further confirming the presence of high-grade mineralisation in the known lodes.
“It has also established the new geological theory that the mineralisation extends into the oxide zone to the northeast of the Crown Prince in areas never previously tested.”
Thundelarra's Garden Gully Gold Project's prospects
Thundelarra will focus its next exploration efforts on the northeast structural corridor that has not been drilled previously.
It stated: “Multiple high-grade zones appear to be present within the weathering profile in this confined structural corridor.
“This area offers significant potential for previously undiscovered near-surface high-grade oxide gold mineralisation.”
Crown Prince is found at of one of 15 prospecting licences that comprise the wholly-owned 78 square metre Garden Gully project, about 20 kilometres northwest of the town of Meekatharra.
Garden Gully is a former mine where about 21,000 ounces grading about 21 g/t was produced historically over the five years to 1915, primarily from Crown Prince, to maximum depths of 120 metres.
