At Koh-i-Sultan, Chagai Resources is exploring an extensive system of intensely altered breccia and volcanics covering an area of more than five square kilometers on the margin of an extinct volcanic caldera (See Fig. 2). The company has undertaken 3 phases of drilling at Koh-i-Sultan. In late 2005, strong gold mineralisation was intersected in one of 2 percussion holes (LRM-01) drilled on the western margin of the system in late 2005.

In 2008, a five-hole diamond drilling program totaling 2284 m (see Figs. 2 & 3 for drillhole locations) resulted in two new discoveries:

  • Porphyry-type copper-gold mineralisation in drillhole LRMDDH-002 (392 – 520 m, 128 m @ 0.14%Cu and 0.19 ppm Au) and
  • very large, variably-altered and mineralised breccia complex, intersected in all five drillholes, over a width of more than 700 m and a north-south extent of more than 400 m. Geologically significant gold values were intersected in the breccia in four of the five drillholes. It is believed that the southern extension of this breccia also hosts the gold mineralisation intersected in drillhole LRM-001.
