DRILLING TO RESUME AT ANGKOR GOLD’S CHINA WALL PROSPECT, CAMBODIA
GRANDE PRAIRIE, ALBERTA (September 9, 2014) ANGKOR GOLD CORP. (TSXV: ANK) (“ANGKOR”) has concluded exploration for the season on our China Wall prospect in Andong Meas tenement, Ratanakiri Province, Cambodia. This work involved detailed geological mapping, termite mound geochemistry and an induced polarization (IP) survey. Drilling is planned for the dry season on this and other prospects.
China Wall is one of many targets being explored aggressively by the Angkor / Tohui Beishan alliance. The geology and geochemistry complement the IP beautifully, indicating a copper-molybdenum mineralised porphyry intrusive with peripheral Au epithermal mineralization.
Detailed creek mapping showed mainly propylitic altered granite and granodiorite, and local clustered pyrite mineralization either in small veinlets or in vuggy quartz. Geology along the creeks highlighted a swarm of sulphidized andesite-diorite dykes, with an average orientation of 020o; vertical dip (70 to 80o E) and matrix pyrite mineralization up to 10%, intruding the granite.
The geological mapping and ground IP were done under contract by Beijing Explor-Tech Engineering Co. Ltd. (Betec) and the China Chemical Geology and Mine Bureau Shandong Geological Prospecting Institute (SI) over a 25km2 area. They were supported by Angkor’s staff, who undertook a concurrent 16km2 termite mound geochemical survey over the northern part of the IP survey, collecting and processing almost 13,000 samples. Results of the IP survey are shown below, superposed on the aeromagnetic map with the principal anomalous zone coinciding with a magnetic low. Only a single vertical depth probe was possible before the rains set in.
The resistivity shows a very clear ring structure, surrounding the chargeability high, which, in turn, is concentric about a central resistive high.
Termite mound geochemistry is equally compelling. There are unequivocal copper and molybdenum anomalies that coincide precisely with the anomalous IP, as depicted on the maps below:
The single vertical pseudo-profile (line ‘A’-‘B’ in the maps above) that was completed indicates that this surface chargeability has the shape of an inverted ‘U’, with strong chargeability confined to the perimeter and down some 150m in the north and over 300m in the south. This fits our previous interpretation from mapping, and the 3 drill holes completed in 2012, of a multi-phase intrusive body with a halo of sulphide mineralization at the intrusive contact margins.
The coincident copper-molybdenum and IP anomalies present an excellent target for drilling, but prudence dictates that at least a further 3 deep sounding 3D IP lines be completed before drilling commences.
All termite samples were analysed in-house for base metals by X-Ray Diffraction, which has been calibrated against some 2500 samples sent for ICP-MS analyses by ALS-Chemex. Duplicate, blank and standard QA/QC samples are run on a random basis which average 10 samples per 100, and instrumental drift adjustments are made on the basis of the blanks and standards every 100 samples. Gold estimates are made by panning a 1kg sample of termite mound material to a heavy mineral concentrate, then counting the number and relative sizes of gold grains observed in the pan. The resulting “gold index” is a purely empirical number, used in-house as a prospecting tool. Geophysical work was done under contract by Betec, under the joint field supervision of contract geologists from SI and ANGKOR’s staff geologists.

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.
ANGKOR GOLD CORP., a public company listed on the TSX-Venture Exchange, is Cambodia’s premier gold explorer with a significantly large land package and a first-mover advantage with excellent relationships at all levels of Government (local to national).
