In public announcements to date, Santana has estimated a 2 million ounce global inferred resource, including significant high grade resources.
Some holes have yielded what the company describes as "exceptional" mineralised intercepts and results from other holes had added weight to the discoveries.
Santana will continue drilling the four defined resources and also extend activities along the 30km Bendigo-Ophir mineralised trend.
The company has also raised about $9 million through the issue of new shares so it can expand its drilling programme within the 292 sq km permitted project area.
During the June quarter, Santana spent $1.65 million on its New Zealand activities and $6000 on exploration and holdings costs in Mexico.
"We really have opened up the prospect of future underground mining of the deeper parts of the Rise and Shine [RAS] deposit if RAS continues further down plunge, which our geological model suggests it should," chief executive Dick Keevers said.
