White Cliff Minerals Limited (ASX: WCN), headquartered in Australia is engaged in the business of exploration and development of minerals. The company is currently working on two projects – cobalt-nickel projects in Western Australia and high-grade Aucu Gold-Copper Project in the Kyrgyz Republic.
White Cliff has reported a maiden Inferred Mineral Resource of nickel-cobalt deposit at the Ghan Well in harmony with the JORC Code guidelines. The resource reported consists of 1.3 million tonnes with an average grade of 0.9% nickel (which is above a cut-off grade of 0.8% nickel) and 0.07% cobalt. In value terms, it contains 11,900 tonnes of nickel and 900 tonnes of cobalt.

The mineralisation appears to be a flat-lying, undulating body, occurring as clays (oxide) to saprolitic ultramafic above the fresh ultramafic rock. The main zone of mineralisation is stretched over 850 metres east-west and 700 metres north-south, separated into two main zones in the south which combine into a single zone to the north. The thickness of the mineralisation varies from 1-2 m to 40 m.
The deposit reported is shallowly drilled in most areas and thus provides considerable scope to increase the resource with further drilling. There is an additional possibility of nickel and cobalt mineralisation along 3 km to the north, and 6 km to the south as the ultramafic host rock becomes significantly wider just next to the south of nickel-cobalt deposit.
Before further drilling, the company is looking for options that may add value to the project like preliminary metallurgical test-work to validate rock characteristics and metal recoveries.
Late in March, White Cliff reported the existence of maiden nickel – cobalt resource of 5.7 million tonnes at Coronation Dam. The nickel-cobalt deposit at the Ghan Well is the second Inferred Mineral Resource discovered by White Cliff Minerals in the same region after the one identified at Coronation Dam.
A moderate Inferred Mineral Resource of both nickel and cobalt has been identified by the company through further drilling and subsequent resource modelling within a 700-metre long section of the expected ultramafic sequence along the Company’s area.
To immediately south of the Inferred Mineral Resource, the possible ultramafic unit is stretched over 6 km. This unit has not yet been tested for nickel and cobalt mineralisation and thus provides an opportunity for further identification of the inferred resource.
White Cliff Minerals was indulged in many cobalt-nickel projects like Coronation Dam Cobalt Project, Ghan Well Cobalt Project, Coglia Well Cobalt Project, Bremer Range Cobalt Project and Merolia Nickel Project. Apart from cobalt-nickel projects, it was involved in many gold projects including Kyrgyz Copper-Gold Project, Ironstone Gold Project and Laverton Gold Project.
Earlier, the company conducted bulk sampling along a section of the Chanach river alluvial terraces to assess the gold concentration in the samples. In March, the company reported the gold assays for the bulk samples collected previously and reported gold concentrations in the bulk samples.
The company’s stock is currently trading flat at AUD 0.006 on ASX (as at Thu 18 Apr 2019, 2:15 PM AEST).
