ANGKOR Gold Corporation is increasing exploration programs in Ratanakiri province after signing a definitive agreement with Tohui Beishan Property Group Holding Limited (TG) of Hong Kong. Angkor has contracted Beijing Explo-Tech Engineering Co (BETEC) and the China Chemical Geology and Mine Bureau Shandong Geological Prospecting Institute (SGI), which have commenced work alongside Angkor’s geological team.
Work on the Andong Meas Exploration Licence area shows two zones of particular interest, Wild Boar and China Wall prospects, which have both seen extensive artisanal mining.
Soon after Angkor acquired the property in April 2012 a program of three scout diamond drill holes totalling 521 metres on the China Wall prospect returned high silver values over good thicknesses (6.13 grams/tonne silver over 18.7 metres; 15.98 grams/tonne over 20.4 metres; 14.52 grams/tonne over 7.5 metres), some exceptional molybdenum (0.025% over 8.0 metres; 0.023% over 8.1 metres; and 0.014% over 45 metres), and excellent tungsten values (0.017% over 11.3 metres; 0.027% over 9.5 metres; and 0.025% over 9.6 metres).
Exploration has continued since then, including reconnaissance termite mound geochemistry coupled with geological mapping, a clay alteration survey and ground magnetic and electromagnetic geophysical surveys. This work shows a strong multi-element termite mound geochemical anomaly over, and to the east and southeast of China Wall and another over the Wild Boar prospect, which covers stacked polymetallic epithermal to mesothermal quartz-carbonate veins.
Panning from stream outwash gravels immediately southeast of China Wall showed good concentrations of gold, some of it crystalline which is indicative of close proximity to source.
The next step is a strong push of detailed geological mapping, termite mound geochemistry and induced polarization geophysics over both areas. BETEC and SGI will work in close association with Angkor’s geological team to run this survey over an area of 25sqkm with a view to defining drill targets for later in the season. A team of 11 geoscientists from these two contractors is deployed with Angkor’s own team of 54 staff, including four of Angkor’s international geologists on Andong Meas tenement.
On the Wild Boar prospect the IP and geochemical work is targeting several polymetallic quartz-carbonate veins on which there are extensive artisanal workings, and from which grab samples showed gold grades from 3.22 to 13.58 grams/tonne. Some samples had elevated silver and lead values as well.
On the Okalla prospect in Banlung Exploration Licence area, where Angkor has drilled 7823 metres in 43 diamond drill holes on a gold-copper-molybdenum bearing diorite porphyry, BETEC and SGI will deploy a further team of six earth scientists to extend eastwards and to the north the IP and geology work done originally on this prospect. The team, with additional Angkor staff, will cover a block of roughly 15sqkm.
