Herencia Resources plc announced that a new comprehensive geological review of the company's core copper mineral prospects has been completed as a precursor to a broad drilling program on the prospects. The review was conducted by Mr. John Holliday who was involved in the discovery of the Cadia Mineral field in Australia. John has worked extensively on copper geology throughout the world and will be retained by Herencia as its Geological Advisor. The review covered all previous drilling and exploration work and was conducted on the Picachos, Montenegro and the largely unexplored Pastizal property. The company is now planning the scope of its exploration program which will commence shortly.
