Herencia Resources PLC18 July 2007 18 July 2007 For immediate release Herencia Resources plc ("Herencia" or the "Company") High Grade Drilling Results at Paguanta Zinc-Silver Project Highlights: • Paguanta Project - High Grade Zinc, Silver and Lead Results o 5,000 metre reverse-circulation (RC) drill program nearing completion at Paguanta with over 4,000 metres drilled to date. o Results from the first three holes drilled into the main 'Patricia' zone intersect mineralisation and return high grade zinc, silver and lead assays. o Highest individual grades of 18.4% Zn, 374 g/t Ag, 8.13% lead and 3.11 g/t Au returned (1m samples). Herencia Resources Plc holds a 50% interest in the Paguanta Project in NorthernChile and is in the process of increasing this interest to 70%. Paguanta Project The Paguanta Project, located on the northern end of the Chilean Porphyry CopperBelt, is approximately 150km east of the port of Iquique and 20 km south of anational highway. Paguanta contains old silver-lead-zinc workings, inparticular the Englishman Mine encompassing the 'Patricia' zone, which wasdeveloped over 100 years ago. Previous surface and underground sampling by Herencia had identified a onekilometre long zinc, silver and lead anomaly. Diamond drilling in December2006 had indicated that the Patricia mineralisation is hosted by at least threesub-parallel, steeply dipping structures. These generally have a core ofhigher grade zinc, silver and lead mineralisation within a broader mineralisedzone. Drilling Program - Initial Results A 5,000m RC drill program was commenced in June 2007 and is anticipated thiswill be completed before the end of July. Approximately forty (40) holes arebeing drilled at nominally 60m to 80m spacing. Drilling is predominantlytargeting the Patricia zone near surface to test the open pit potential of themineralisation. The results from the first three holes have been received with the significanthigher grade intercepts as follows: Hole ID Width From Zinc % Silver (g/t) Lead % Comment PTRC001 24m 18m 4.36 86 1.29 Camp veinincludes 3m 27m 5.55 61 1.08 0.87 g/t Au 7m 34m 8.13 192 2.42 1.15 g/t Au PTRC006 33m 107m 4.28 59 1.00 Cathedral veinincludes 9m 108m 8.53 116 1.68 0.43 g/t Auincludes 1m 127m 10.05 34 0.66includes 4m 135m 7.37 92 1.85 PTRC007 18m 89m 8.45 123 2.61 Cathedral veinincludes 6m 100m 13.27 199 4.49 0.44 g/t Au Notes: • Zn, Ag, Pb and Au analysed by Atomic Absorption Spectrometry (AAS). • All intervals are downhole widths. Maximum individual drill assays received to date (1m samples widths) are 18.4%Zn (PTRC007), 374 g/t Ag (PTRC001), 8.13% lead (PTRC007) and 3.11 g/t Au(PTRC001). Hole PTRC001 was drilled approximately 40m down dip of PTDD001 (a diamond holedrilled in December 2006), PTRC006 was drilled approximately 40m down dip ofPTDD004 (a diamond hole drilled in December 2006) and PTRC007 was drilledapproximately 60m west of PTRC006. The drill results demonstrate that the highgrades previously encountered in the diamond drill program have been repeateddown dip in the Camp vein and both down dip and along strike in the Cathedralvein. Commenting on the results, Executive Director Michael Bohm said "Following onfrom the results achieved in the previous drill program at Paguanta, it isexciting to see near surface high grade mineralisation being repeated in thesefirst three holes of the current drill program". It is anticipated that the current drill program will be completed by month endwith all assay results expected to be received by the end of August 2007.Those results will be released thereafter as they are received.
