Middle Island more than doubles Wirraminna gold resources to 23,000 ounces

Middle Island Resources Ltd. said Dec. 8 that resources at the Wirraminna deposit of its Sandstone gold project in Western Australia more than doubled, to 23,000 ounces of gold contained within 550,000 tonnes averaging 1.3 g/t of gold, using a 0.5 g/t cutoff.

About 55% of the resource is in the higher-confidence indicated category, with the rest classified as inferred.

The previous Wirraminna estimate outlined inferred resources of 106,300 tonnes at 2.07 g/t of gold for 10,674 ounces.

The company attributed the increase to a higher degree of mineralized zone continuity, as demonstrated by infill and extension drilling, as well as the use of a lower cutoff grade.

Middle Island will undertake pit optimization of Wirraminna to assess its potential contribution to the planned production schedule for Sandstone, which is expected to be completed by the end of the month.

The company also highlighted potential to further extend and enhance the Wirraminna deposit through follow-up reverse circulation drilling, including confirmation of historical higher-grade holes and infill drilling to upgrade inferred resources.
