GRANDE PRAIRIE, Alberta, Nov. 7, 2014 (GLOBE NEWSWIRE) -- A research program on the Otray prospect funded by ANGKOR GOLD CORP. (TSXV:ANK) ("ANGKOR") at the Mineral Deposit Research Unit of the University of British Columbia, has confirmed the presence of polymetallic epithermal mineralization on the company's Oyadao South tenement in Cambodia. Mineralization was initially discovered in the Otray prospect area with a termite mound geochemical survey in 2012 (see Press Release dated 2013 May 29), following up on regional mapping, stream sediment sampling, and an aeromagnetic survey that indicated a prospective structural zone south of the Phum Syarung gold project.
The project has utilized surficial mapping techniques, short wave infrared spectroscopy (SWIR), termite mound geochemistry, 'C' zone soil geochemistry, structural analysis, geochronology, and petrography. The final goal of the research to is to understand the genesis, timing, and the geochemical signature of the deposit to guide further exploration in the region.
Coinciding with the base metal geochemical anomaly in Otray, a series of stacked quartz veins with disseminated sphalerite, galena, and pyrite were discovered during the last field season. Three veins have been discovered to date, with quartz float blanketing the area surrounding the termite geochemical anomaly. Potentially, the mineralized quartz veins could span the entire 2.5 km strike length of the geochemical anomaly. Rock chip geochemistry from the area shows some exciting values of base and precious metals:

SWIR analysis of grab samples from the field has indicated that the geochemical anomaly is surrounded by argillic alteration (kaolinite, dickite, illite) with advanced argillic alteration (Na-alunite, diaspore, dickite, halloysite, pyrophyllite, jarosite, and vuggy silica) to the west, and isolated pods of phyllic alteration (pyrophyllite and sericite). Advanced argillic alteration was encountered along with highly silicified lithocap material and the majority of the hills to the west of the Otray prospect area. Accordingly, a reconnaissance IP program of 4 lines is planned for 2015, with a view to designate three or more drill targets for the latter part of the dry season.
"The surface data collected in the Otray prospect over the past two seasons continues to create a beautiful picture of the exposed portions of this well-mineralized system," says Craig Richardson, the Otray Project Geologist. "The geophysics program planned for the upcoming field season will produce our first images of the prospect in the third dimension and put us one step closer to drilling."
The rock samples were analyzed for base metals by ICP-MS after 3 acid digestion and for gold by standard fire assay by ALS-Chemex. Angkor's QA/QC protocol required semi-random insertion of calibration standards and blanks at a rate of 10 per 100.

ANGKOR's 7 exploration licences in the Kingdom of Cambodia cover 1448 km2, which the company has been actively exploring over the past 5 years. The company has now covered all tenements with stream sediment geochemical sampling; has flown low level aeromagnetic surveys over most of the ground; drilled 18,737 metres of NQ core in 148 holes; and has collected in excess of 20,000 augered 'B' and 'C' zone soil samples and 55,000 termite mound samples in 17 centres of interest, over a combined area of 85km2, in addition to numerous trenches and detailed geological field mapping. Exploration on all tenements is ongoing.
