An updated reserves estimate for the Redbeard gold deposit, part of Millennium Minerals Ltd.'s Nullagine mine in Western Australia, outlined 153,000 tonnes grading 3.5 g/t for 17,200 ounces in the probable category.
The company said July 3 that production from the oxide deposit is on track to start later in the month.
Reserves are included within measured and indicated resources and surveyed stockpiles and were estimated using a cutoff of 0.7 g/t.
Millennium said the Redbeard analysis represents a resource-to-reserve conversion rate of 76%, making it the highest-grade deposit defined to date at Nullagine. Deeper drilling is underway on the Redbeard deposit as part of the company's plans to assess a potential underground operation.
The company is also planning to complete initial resource estimates for the Golden Gate mining center, which is next to Redbeard and was last mined in 2014.
