Caribou King Reports Flotation Test on Second Sample from Uncle Zone Yields >99.9% Graphitic Carbon

- March 17th, 2015

Caribou King Resources (TSXV:CKR) reported that the flotation test from the second sample taken from the “Uncle Zone” at the Buckingham flake/lump graphite property yielded >99.9% Cg. The two samples from the Uncle Zone yielded exceptional results and indicate that material is widespread and could also be qualified as ultra-high-grade graphite. A metallurgical study for the Uncle Zone is now top priority, together with an aggressive exploration program.

The two samples from the Uncle Zone yielded exceptional results and indicate that material is widespread and could also be qualified as ultra-high-grade graphite. A metallurgical study for the Uncle Zone is now top priority, together with an aggressive exploration program.

As quoted in the press release:

This second sample was taken from the wall of a historic trench, located roughly 250 metres ESE of the previously announced sample that yielded purity of up to 99.4% Cg (see PR dated February 17th, 2015). Both samples were taken from the “Uncle Zone”, a ~600 meter wide area of mineralization in the SE portion of Buckingham Property, and assays were conducted by SGS Canada Inc. (Lakefield).

The second sample, with a head grade of 56.0% Cg (58.3% total C), was concentrated by grinding and flotation and divided into three size fractions: +48, +100 and -100 mesh. The +48 mesh size (jumbo size) fraction represented 31.6% of the flotation concentrate and assayed >99.9% Cg*. The +100 mesh size (medium to large size) fraction represented 25.3% of the flotation concentrate and assayed >99.9% Cg*.

These results were obtained in a single flotation test without process optimization such as acid leach or alkaline roast. Exceptional results from the two samples collected 250 metres apart are extremely encouraging as they indicate that material is widespread within the “Uncle Zone” and could also be qualified as ultra-high-grade graphite.

Caribou King has therefore decided to make metallurgical studies a top priority in parallel to an aggressive exploration program at its “Uncle Zone”. Purity of Buckingham graphite is to be further defined by additional tests as to get the maximum benefit from it.
