The first drill program at Altan Rio Minerals’ Khavchuu gold project in the Tov province of northern Mongolia is under way. The 7sqkm project contains significant geophysical and gold-arsenic geochemical anomalies in a Boroo mine-type orogenic gold setting and has never been drilled.

Altan Rio says six diamond core drill holes covering 1800 metres across three main targets will test a large tract of geology over an area of about 5 x 6 km, searching for key structural features such as low-angle fault zones.

The general geological setting at Khavchuu is very similar to nearby Boroo and surrounding deposits such as Ulaan Bulag. Economic gold mineralization in the district is dominated by large tonnage quartz-sericite-sulphide alteration zones, commonly known as ‘QSP’, in granitoids. The QSP alteration is readily imaged by IP surveys which show chargeability highs and magnetic surveys which show coincident moderate low zones (magnetite destruction).

In 2011, Altan Rio performed rock sampling and detailed soil geochemical grids in the northwestern quarter of the project, which confirmed robust arsenic anomalies coincident with IP chargeability highs as well as low-level gold anomalies.

The company’s president Evan Jones says this combination - coincident gold, arsenic and IP highs - is fundamental to all economic deposits discovered thus far in the Boroogol district.

Drilling is expected to be finished next month. Altan Rio’s licence holdings in Mongolia total more than 153,310 hectares and contain significant zones of newly identified primary gold and copper mineralization across a very large area of unexplored ground.
