Caribou Achieves more than 99.9% Graphitic Carbon From Flotation Test on Second Location on Uncle Zone, Quebec

equities Canada |

VANCOUVER, BRITISH COLUMBIA--(March 3, 2015) - CARIBOU KING RESOURCES LTD. ("Caribou" or the "Company") (CKR:CA) (FRANKFURT:CB8) is pleased to announce exceptional preliminary results from its first beneficiation test at a second location sample on the 100% owned Buckingham flake/lump graphite property.

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*.

Initial Flotation Test Results

Concentrate Fraction Distribution (%) Assay (% Cg)
+48 mesh 31.6 >99.9*
+100 mesh 25.3 >99.9*
-100 mesh 37.3 96.5
Total recovery (%) 94.2  
* Assay results for +48 mesh and +100 mesh returned values of 101.5% Cg and 100.2% Cg respectively, and are shown above as >99.9%. Further testing is currently being carried out to verify these values. All reported results have an associated measurement uncertainty based on the expected precision and accuracy relating to the method and sample concentration. Values at 100% should not be treated as pure products without additional impurity testing. Testing by party and/or umpire analysis will reduce, but not remove measurement uncertainty of the method.
Note: Flotation test analysis from a 1kg portion of the 2kg grab sample

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.

Michael B. England, CEO & Director of Caribou King stated, "Needless to say, these results are highly encouraging. They suggest that mineralization at the Uncle Zone is high purity and also extends for a considerable distance."

All carbon analyses were performed by SGS Canada Inc. (Lakefield) and are reported as graphitic carbon Cg employing a LECO SC-632 instrument. The results reported in this release are from a single trench and are not necessarily representative of all mineralization hosted in this zone. Further testing must be carried out to verify these results.

(Lakefield) and approved the technical information provided in this news release.

About the Buckingham Property

The 100% owned Buckingham Graphite property, covers 480 hectares and is located 7km northwest of Buckingham, Quebec, Canada. Well-maintained bush roads lead directly to the sampled showing and throughout the property. The property is comprised of eight claim blocks within the Central Metasedimentary Belt of the Grenville Geologic Province with graphite occurring in veins and masses within pegmatite, diopside skarn, marble and gneiss.
