Sunstone Metals (ASX:STM) starts drilling at T2 porphyry target, El Palmar

Sunstone Metals (ASX:STM) has begun drilling at the T2 porphyry target within its El Palmar porphyry discovery in northern Ecuador, with highly encouraging results from T1 and T5 which are adjacent to T2.

Sunstone Metals says T2 is a large target measuring 1km long x 450m wide, which is part of a cluster of at least five porphyry systems that measures 2.6 x 1km.

It also says it's bound by the regionally-significant Toachi Fault zone and is associated with orthogonal structures, very similar to the 3 billion-tonne Alpala copper-gold porphyry deposit within SolGold's Cascabel project, 65km away.

Sunstone Metals says whilst the three targets are mineralised, drilling is still to be done at T3 and T4.
