Pantoro Ltd. said it raised the total ore reserve at its Nicolsons gold project in Western Australia by 62%, to 773,252 tonnes at 7.35 g/t for 182,823 ounces.

The ore reserve provides a base case life of about four years, with potential for further increases through drilling and mine development, according to a May 31 release.

The mineral resource at the project now totals 1.58 million tonnes at 7.43 g/t of gold for 376,701 ounces.

The May 2016 estimate for measured, indicated and inferred resource for the entire Halls creek projects stood at 1.04 million tonnes grading 6.52 g/t of gold for 217,581 ounces.
