- New assays received from Coronation Dam, results include:
o 40 metres at 0.22% cobalt and 1.75% nickel from 8 metres
o 36 metres at 0.10% cobalt and 0.87% nickel from surface
o 16 metres at 0.11% cobalt and 0.88% nickel form 18 metres
o 20 metres at 0.06% cobalt and 0.75% nickel from 8 metres
o 21 metres at 0.06% cobalt and 0.8% nickel from surface
o 10 metres at 0.04% cobalt and 1.3% nickel from 20 metres
- Final composite assays expected shortly
Drilling results are from the four cross sections drilled either side of the sections previously reported and extent the high grade mineralisation to over 600 metres long, 400 metres wide and up to 56 metres thick (average 20 metres). Mineralisation has developed in the regolith profile above an intensely weathered ultramafic unit which was originally a peridotite. The peridotite is approximately 1 kilometre wide and 5.7 kilometres long within the mining tenement which covers 16km2. Results include:
CDRC0071 40 metres at 0.22% cobalt and 1.75% nickel from 8 metres
CDRC0070 20 metres at 0.06% cobalt and 0.75% nickel from 8 metres
CDRC0069 12 metres at 0.08% cobalt and 0.8% nickel from 32 metres and;
12 metres at 0.04% cobalt and 0.8% nickel from 64 metres
CDRC0030: 4 metres at 0.11% cobalt and 0.90% nickel from 36 metres
CDRC0031: 12 metres at 0.04% cobalt and 0.74% nickel from 20 metres
CDRC0032: 16 metres at 0.11% cobalt and 0.88% nickel from 18 metres
CDRC0033: 36 metres at 0.10% cobalt and 0.87% nickel from surface
CDRC0034: 16 metres at 0.07% cobalt and 0.82% nickel from surface
CDRC0013: 10 metres at 0.02% cobalt and 1.0% nickel from 2 metres
CDRC0014: 21 metres at 0.06% cobalt and 0.8% nickel from surface including;
2 metres at 0.08% cobalt and 1.3% nickel from surface
CDRC0015: 10 metres at 0.04% cobalt and 1.3% nickel from 20 metres
CDRC0020: 12 metres at 0.05% cobalt and 0.57% nickel from 12 metres
CDRC0021: 4 metres at 0.01% cobalt and 0.60% nickel from 16 metres
White Cliff Managing Director Todd Hibberd said: "Further assays at Coronation Dam continue to demonstrate the high grade nature of the cobalt mineralisation. The mineralised zone is now over 600 metres long, 400 metres wide and up to 56 metres thick (average 20 metres). Further assay results should be available shortly and on receipt of the final drilling results the Company will be in a position to complete a geological and mineralisation model and to select samples for metallurgical testing".
The Coronation Dam Cobalt Project
The Coronation Dam Cobalt Project is located 90km south of Glencore's Murrin Murrin mining operation and 45km south of GME Resources' proposed Mt Kilkenny nickel-cobalt processing facility in WA's north-eastern goldfields (see Figure 2 in link below). The project is surrounded by world class mining infrastructure and multiple operating mines. Glencore is currently mining cobalt and nickel from the Murrin East open pit which contained an initial resource of 66 million tonnes at 1.1% nickel and 0.09% Cobalt.
The Coronation Dam project area covers 16km2 and contains an outcropping ultramafic unit that is approximately 1 kilometre wide and 5.7 kilometres long within the tenement.
Cobalt-nickel mineralisation occurs as a shallow layer of cobalt-enriched manganiferous oxides that form between the smectite clays and the overlying ferruginous clays. High grade cobalt mineralisation typically occurs between the surface and 50 metres depth and is associated with nickel mineralisation.
Existing drilling has only partly tested the mapped ultramafic unit, indicating there is potential to identify significant additional mineralisation.
The proximity of Coronation Dam to the Murrin Murrin nickel refinery is likely to have a strong, positive impact on the possibility of economic development of both the cobalt and nickel mineralisation. While the Company has not yet calculated a mineral resource, it is clear that the potential exists for the project to host one of substantial size.

About White Cliff Minerals Ltd
White Cliff Minerals is a Gold, Copper, Cobalt, Nickel resources and mining company listed in Australia (ASX:WCN). The Company is focused on developing low cost high value mineral deposits that have near term cash flow potential.
Major projects include the Aucu gold deposit that contains 484,000 ounces of gold (3mt at 5.1 g/t) starting at surface and Chanach copper deposit that contains 64,000 tonnes of copper (17.2Mt at 0.37% copper). Both projects have substantial blue sky potential with drilling covering only 5% of the known structures. In Australia the company is developing the Coronation Dam cobalt–nickel deposit where a maiden resource will be announced in the late 2018.
