Caribou King Yields 99.3% Graphitic Carbon From Initial Purity Test
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Feb 10, 2015) - Caribou King Resources Ltd. ("Caribou" or the "Company") (TSX VENTURE:CKR)(FRANKFURT:CB8) is pleased to announce exceptional preliminary results of up to 99.3% graphitic carbon (Cg) from its first beneficiation test conducted by SGS Canada Inc. (Lakefield) on the 100% owned Buckingham flake/lump graphite property.
The 2 kilogram (kg) surface sample, taken from an exposed vein with a head grade of 55.8% Cg (57.9% total C), was concentrated by grinding and flotation and divided into three size fractions: +48, +100 and -100 mesh. All three concentrates returned high grade graphitic carbon (Cg) content with very little losses in the tailings and middling streams. The +48 mesh size (jumbo size) fraction represented 36.6% of the flotation concentrate and was assayed at 99.3% Cg. The +100 mesh size (medium to large size) fraction represented 25.6% of the flotation concentrate and was assayed at 98.8% Cg. The -100 mesh size (fine to amorphous) fraction represented 32.7% of the flotation concentrate and was assayed at 95.3% Cg. These results are summarized in the following table:
Initial Flotation Test Results
Concentrate Fraction | Distribution (%) | Assay (% Cg) |
+48 mesh | 36.6 | 99.3 |
+100 mesh | 25.6 | 98.8 |
-100 mesh | 32.7 | 95.3 |
Total recovery (%) | 94.9 |
*Flotation test analysis from a 1kg portion of the 2kg bulk sample. |
Results were obtained in a single flotation test without process optimization. A full process development study including grinding and flotation optimization is anticipated to return higher flotation concentrate recoveries and grades, thus reducing the operating cost of a downstream purification process.
These positive results at Buckingham have triggered an extensive follow-up program now being planned by the Company.
Michael B. England, CEO & Director of Caribou King stated, "After just an initial traditional flotation test, Buckingham has yielded a concentrate that assayed 99.3% Cg which is extremely encouraging, especially when considering that they were obtained in a single set of tests without any process optimization."
All carbon analyses were performed by SGS Canada Inc. (Lakefield) and are reported as graphitic carbon Cg employing a LECO SC-632 instrument.

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.
