Kaminak Reports Heap Leach Oxide Gold Recoveries of Greater Than 85% on 6 Inch Crushed Material from Coffee

VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 04/17/14 -- Kaminak Gold Corporation (TSX VENTURE: KAM) wishes to announce additional, encouraging, column leach metallurgical results from bulk, course crush, surface oxide samples collected in 2013 at the Coffee Gold Project, 130 km south of Dawson City, Yukon. Gold recoveries between 85-88% were returned within a 100-150 day leach period from 6" crush samples collected from surface trenches at both Supremo and Latte. Corresponding samples crushed to 1" returned gold recoveries of 92% over the same period. No agglomeration was required. The 2013 metallurgical program is now complete and final results are being incorporated into a Preliminary Economic Analysis ("PEA"), which is underway and scheduled for completion in the second quarter of 2014.

Fred Lightner, Director Mine Development, stated:

"The metallurgical testing results continue to illustrate the amenability of the Coffee deposits to heap leaching. Once again, the excellent recovery at the 1" crush size of over 90% has been demonstrated. The high recoveries 85% to 88% at the 6" crush size provide potential for treating lower grade ores by very coarse crushing, and even perhaps run-of-mine (ROM) leaching. These final results of our 2013 Metallurgical program will provide valuable input for the Preliminary Economic Assessment, currently in progress."

Highlights from this work include:


--  Column leach gold recoveries of 85% and 88% on 6" crushed material from
    bulk surface Oxide samples from each of Supremo and Latte

--  Corresponding bulk surface oxide samples crushed to 1" for both Supremo
    and Latte produced a recovery of 92%

--  Column leach test work for the 1" samples was conducted under simulated
    cold climate conditions. The 6" crush columns were too large to be
    contained in the refrigerator and were leached at ambient temperature.
    Previous work has shown only a minor (-1%) gold recovery difference
    between ambient and cold climate leaching.

--  Bottle roll gold recoveries were not substantially increased compared to
    the column leach tests, which is consistent with previous results,
    indicating that heap leaching is a more attractive option than agitation
    leaching at this stage of the project.

Results of the recent column leach tests, conducted by Kappes, Cassiday and Associates ("KCA") are summarized below in Table 1.

Comparative Bottle Roll Test Work

Results from bottle roll test work undertaken on splits of the same composites utilized for column leaching are detailed below in Table 2. Again it was observed that at a fine grind, recoveries were not substantially increased over the column leach tests, indicating that heap leaching will most probably be economically more attractive than agitation leaching.

Bulk Samples for the 2013 Metallurgical Test Program

Locations for collection of metallurgical samples were selected by examination of the resource block model for material that would be representative of average gold grade. The Supremo Oxide sample was collected from a surface trench across the T3 mineralized structure at 6974250mN. The Latte Oxide sample was collected from a surface trench across the Latte mineralized structure at 583250mE. Trenches were excavated to bedrock and sampling was completed on 2m intervals. A total of 1500kg of material was collected from each trench and was sent to KCA where it was homogenized prior to splits being taken for the analytical work presented above.
