Herencia Resources PLC01 August 2007 1 August 2007 Herencia Resources plc ("Herencia" or the "Company") Further High Grade Drilling Results Highlights: • Paguanta Project - Further High Grade Zinc, Silver and Lead Drilling Results • Assay results received from sixteen holes drilled into the 'Patricia' zone at Paguanta. • High grade intersections (in addition to those high grade results announced on 18 July) include: • 8m at 9.82% zinc, 280 g/t silver and 5.55% lead from 68m in hole PTRC008; and • 15m at 6.8% zinc, 92g/t silver and 1.6% lead from 106m in hole PTRC014 including 5m at 13.7% zinc, 222 g/t silver and 3.92% lead. • Near surface zinc/silver/lead mineralisation now confirmed on the Cathedral vein over a strike length of 500m and up to 130m down-dip from surface. Paguanta Project Herencia Resources Plc holds a 50% interest in the Paguanta Project in NorthernChile and is in the process of increasing this interest to 70%. The project,located on the northern end of the Chilean Porphyry Copper Belt, isapproximately 150km east of the port of Iquique and 20 km south of a nationalhighway. Paguanta contains old silver-lead-zinc workings, in particular theEnglishman Mine encompassing the 'Patricia' zone. 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, moderate to steeply dipping structures. These generally have acore of higher grade zinc, silver and lead mineralisation within a broadermineralised zone. Drilling Program A 5,000m RC drill program commenced in June 2007 and by the end of July 4,282mof drilling (36 holes) had been completed. Assays results from the firstsixteen holes have now been received with the majority of holes targeting theCathedral vein intersecting high grade mineralisation. Assays received to date are summarised as follows: Hole ID Width From Zinc % Silver (g/t) Lead % CommentPTRC001 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 AuPTRC002 2m 19m - 85 1.48 Camp veinPTRC003 2m 33m - 36 - Camp veinPTRC004 no significant resultsPTRC005 4m 6m - 60 - Camp vein 8m 73m - 36 -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 1.85PTRC007 18m 89m 8.45 123 2.61 Cathedral veinincludes 6m 100m 13.27 199 4.49 0.44 g/t AuPTRC008 8m 68m 9.82 280 5.55 Cathedral veinPTRC009 To be re-drilled Undershot target zonePTRC010 20m 35m 1.57 - - Cathedral veinPTRC011 4m 83m 4.86 94 2.03 Cathedral vein 3m 96m 3.42 87 1.56PTRC012 4m 11m - 44 - Splay from Cathedral veinPTRC013 3m 49m 4.46 73 1.62 Splay from Cathedral vein 4m 76m 2.76 52 1.71 Cathedral veinPTRC014 28m 5m - 40 1.46 Cathedral Hanging-wallincludes 6m 6m - 82 5.05 15m 106m 6.8 92 1.60 Cathedral veinincludes 5m 113m 13.7 222 3.92PTRC015 6m 15m - 49 1.02 Cathedral Hanging-wall 3m 99m 4.45 71 0.77 Cathedral Hanging-wall 4m 105m 4.42 54 1.15 Cathedral Hanging-wall 3m 125m 6.58 22 - Cathedral Hanging-wall 11m 160m 2.50 55 0.93 Cathedral veinPTRC016 11m 84m - 49 0.49 Cathedral Hanging-wall 5m 98m 3.74 80 0.91 Cathedral Hanging-wall 4m 148m 5.05 29 0.31 Cathedral vein 5m 235m 1.35 59 0.78 Notes: . Zn, Ag, Pb and Au analysed by Atomic Absorption Spectrometry (AAS).• All intervals are downhole widths. Significantly, all but one of the holes (PTRC009) drilled into the mainCathedral vein intersected mineralisation. It is believed that this hole mayhave dropped below its intended target and will be re-drilled. Executive Director Michael Bohm summarised the results as follows "we have nowconfirmed that near surface zinc/silver/lead mineralisation in the Cathedralvein extends for 500m along strike and up to 130m down-dip. This strike anddip extent, in conjunction with the high grades achieved, bodes well for theopen pit potential of the Paguanta Project". The drilling contractor is currently conducting on-site maintenance on the drillrig prior to completing the program. This will allow Herencia to receive assayresults for all the holes drilled to date. Given the success of the program todate Herencia will therefore take the opportunity to complete a number ofadditional holes without incurring re-mobilisation costs. This phase willcommence in mid-August and take approximately 10 days.
