La Romana Target
The La Romana target includes a thick zone of stock work and massive sulphide with high copper values (e.g. DDH PR5: 4.68m @ 2.94% Cu). The massive sulphide was discovered by Exxon in the mid-1980’s following drill testing a 1.2 mGal gravity and IP anomaly. Exxon drilled 9 wide-spaced drill holes at La Romana, including 6 drill holes 300-400m apart with intervals of massive sulphide and up to 160m stock work sulphide mineralisation, and 3 drill holes that did not reach the target.
The mineralisation comes to surface at the La Romana mine workings and extends for approximately 1.3 km to the east and west under Tertiary cover sediments. Down-hole misé-a-la-masse shows an anomaly extending from hole PR5, indicating potential for the massive sulphide to extend a further 700m to the east. Further drilling is required potential for a large concealed massive sulphide copper deposit.

The Cañada Honda Trend
The Cañada Honda target is massive sulphide hosted copper and zinc associated with an untested 1.5 x 0.5 km, 1 mGal gravity anomaly along strike from the Aznalcollar mine. The gravity anomaly and geological setting suggests potential for massive sulphide beneath overthrust Devonian sediments. Drilling by Exxon in the 1980’s and Boliden in the 1990’s, also shows copper and gold intervals in thrust faults up dip from the gravity anomaly. The drilling targeted gold mineralization beneath the Cañada Honda mine old mine tunnel but did not test the gravity anomaly.
