Tian Poh Resources (ASX:TPO) has hit copper grades up to 1,100 parts per million and molybdenum grades up to 585ppm during due diligence drilling at the Zuun Mod project in Mongolia.

Intensifying alteration was evident at depth, with geological processes indicated an albite alteration zone could overlay a mineralised zone in Khuvyn Khar porphyry complex of the project area.

Most drilling samples from surface to 244 metres depth returned from 200 to 1,100 ppm copper (average 750 ppm copper) and about 30 to 200 ppm molybdenum (average 206 ppm molybdenum), with highest concentration being 585 ppm molybdenum.

The results were much higher in concentration than samples from the lower part of the hole (244 to 450 metres), where copper averaged 288 ppm in grade and molybdenum averaged 31 ppm.

This work represented the completion of due diligence drilling as part of Tian Poh’s acquisition of Zuun Mod from Erdene Resources (TSX:ERD).

The drilling program was designed to test the Khuvyn Khar North target zone, located on the northeastern part of Khuvyn Khar. The target is selected on the basis of a series of coincident and overlapping geological, geophysical and geochemical features.

These features include gravity, induced polarisation and magnetic responses, as well as the concentration of quartz veins and anomalous mineralisation of copper, silver and gold.
