Gibb River Diamonds (ASX:GIB) has defined a maiden JORC resource – comprising 24,800 tonnes of gold at 1.51 grams per tonne (g/t) for 1,200 ounces (oz) – at historic leach pads at its Edjudina gold project in Western Australia.

The leach pads are located above ground and can be picked up with a front-end loader for direct train transportation, and their mineralisation is expected to complement the resource of the Neta prospect, which measures 378,000 tonnes @1.9g/t for 24,000 oz in the indicated and inferred categories.

Neta’s indicated resource is measured at 110,000 tonnes at 2.2g/t for 8,000 oz of gold.

GIB is busy engaging in discussion around permitting and joint venture possibilities to enable a mine and haul operation at the prospect, with toll treatment enabled through a third-party mill.

Concerning the leach pads, the company has used metallurgical cyanide bottle roll testing to show that gold can be recovered at a grade of 1g/t.

This testing also formed part of the work to achieve the definition of an inferred gold resource for the leach pads, alongside auger drilling data, satellite imagery and Digital Terrain Modelling data.

GIB shares have been trading flat at 3.7 cents.
