Exploration Target For Bramaderos Porphyries

The Exploration Target within the Bramaderos concession is estimated from three areas;

  1. the extensions to the Brama-Alba system that are not captured in the MRE;
  2. mineralisation drilled at Melonal
  3. mineralisation drilled at upper section of the Limon porphyry

The Exploration Target does not include known porphyry mineralisation at Copete, Sandia, Porotillo, Playas, Yeso and the deeper main body of the Limon porphyry. It was decided to not include these areas because Sunstone has not yet completed any or sufficient drilling in these areas. Some historical drilling has been completed at Porotillo. Further work in these areas will be undertaken and they are expected to contribute to an expanded Exploration Target in the future.

The initial Bramaderos Porphyry Exploration Target, reported in accordance with the JORC Code, consists of between approximately 255 and 360Mt at a grade between 0.40 and 0.74g/t AuEq2 (gold + copper) for contained metal of between 3.3Mozs and 8.6Mozs AuEq.

The Exploration Target range is in addition to the initial MRE.

The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource for the target area reported. It is uncertain if further exploration will result in the estimation of a Mineral Resource
