The company, which owns 40% of the El Nino gold and silver operation alongside JV partner Nevada Gold Mines, confirmed in its June quarter earnings report that the Carlin, Elko County site is ahead of its outlined schedule.

"[The JV] is looking at opportunities to move the processing of the ore forward in the overall processing schedule," officials said. "Processing of ore from El Nino is now expected during the current quarter."

The company is current processing stockpiled material, and in the quarter reported a total of 917oz of gold. Processing, Premier said, is a "favourable development" that should result in a positive impact to its production timing as well as cash flow and overall economics.

Nevada Gold Mines is a joint venture that includes Barrick Gold business arm Barrick Gold Exploration. It holds the balance of interest in the El Nino project, which will have both surface and underground elements once in operation.

The mineralised material from the complex will be processed at Barrick's Goldstrike property, which is just south of South Arturo.
