VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 22, 2015) - CARIBOU KING RESOURCES LTD. ("Caribou" or the "Company") (News - Market indicators)(OTCBB:CBULF)(FRANKFURT:CB8) is pleased to announce assay results from the northern "Case Zone" at its 100% owned Buckingham Graphite property in southern Quebec.

Sampling was conducted in the newly discovered "Case Zone", recently reported by Caribou King (PR dated May 14, 2015), which has been found to be host to numerous and widespread graphite showings exhibiting broad horizons of large-flake disseminated and chunk-style graphite.

A total of 17 grab samples were taken in and around the Case Zone (of which 7 are still pending assay). The highest assay of 28.7% was returned from a sample taken near the centre of the zone, from a large former excavation located directly over a historical airborne anomaly. A total of six samples returned values higher than 10.0% Cg, as shown in the table below:

Case Zone - Grab Sampling Results:

Graphite mineralization in all samples was observed as large-flake and disseminated in altered marble/paragneiss horizons. The highest assays show a strong correlation with historic electromagnetic conductors (report DP83-05).

Michael England, CEO and Director of Caribou King, stated: "These assay results are highly encouraging and demonstrate the presence of graphite in yet another area on the Buckingham Property, approximately 700m northwest from our existing Uncle Zone. We are beginning to define a substantial new zone on a property which has already yielded over 99.9% Cg pure graphite from flotation testing alone. The Buckingham property has returned some of the highest assay results reported in Quebec to date and continues to yield great results."

The Case Zone measures at least 900m along strike and up to 350m wide, as indicated by assays, graphite-rich showings, pits and EM anomalies, and remains open on all sides. Graphite mineralization at the Case Zone appears to be primarily hosted along the contact of near-surface, sub-horizontally dipping marble/paragneiss horizons with additional chunk-style large-flake graphite occurring in narrow, steeply-dipping brecciated structures.

The samples were treated at Activation Laboratories Ltd. (Actlabs) using protocol 5D-C, where they underwent drying, crushing with up to 90% passing through a #10 square-mesh screen, riffle splitting (250 g) and pulverizing to 95% passing a 105 micron square-mesh screen. Graphitic carbon (Cg) was determined by multistage furnace treatment and infrared absorption, with a 0.05% detection limit.
