Reference information

Comments No correlation between Cu grades and intensity of metasomatism. Primary Cu halo >300 ppm Cu (5 by 2 km) was outlined by chip samples. Ore bodies are not outlined because exploration works was not enough. There are some quartz veins (0.5 m thickness). Poor CuOx (malachite) dissemination in prophylites. Limonite (G+J) covers only a surface of pyrite veinlets (<0.5%). Quartz sheeted veinlets and pyrite veinlets trending NW are crossed by chlorite veinlets. Main ore stockwork (1250 x 100) [sic] is located on the top of Khok Mountain and elongated in NE direction.
