Assay Results from New vein at Paguanta Project

First hole into Cathedral target extends vein & hits high grade

(Paguanta Zinc-Lead-Silver-Gold Project in Northern Chile)

Highlights:

·; Assays results received from first three holes in current diamond drilling campaign

·; New vein now confirmed by three drill holes

·; Extension to Cathedral high grade vein confirmed by first hole drilled into target zone

·; Gold assay results in all holes

Further to the Company's announcement of 8 March 2010, Herencia Resources Plc (AIM: HER) is pleased to advise that assay results from the first three diamond holes (PTDD035, PTDD036 and PTDD037) in the current drill program have been received from the laboratory.

The results from the first two holes confirm the presence of a new vein located south of the high grade Cathedral vein at the Company's flagship Paguanta Project in northern Chile.

Best intersections from the first two holes are as follows:

·; PTDD035 - 10.5m @ 5.13% zinc, 0.97% lead, 63.4g/t silver and 0.27g/t gold from 59m

including 2.17m @ 17.62% zinc, 3.27% lead, 224g/t silver and 1.08g/t gold

and 3.5m @ 1.81% zinc, 0.61% lead, 30.15g/t silver and 0.36g/t gold from 158.75m

·; PTDD036 - 3.0m @ 2.05% zinc, 0.83% lead, 41g/t silver and 0.19g/t gold from 139.8m

including 1.0m @ 3.56% zinc, 0.92% lead, 55.9g/t silver and 0.45g/t gold

including 0.25m @ 8.37% zinc, 5.01% lead, 193g/t silver and 0.36g/t gold

The results from the above two holes coincide well with those from diamond drill hole PTDD031 (previously drilled and assayed in 2008) which also intersected this new vein and reported the following high grades:

·; 2m @ 11.87% zinc, 5.83% lead, 327g/t silver and 0.34g/t gold from 37m

·; 6m @ 3.61% zinc, 1.17% lead, 57.6g/t silver and 0.66g/t gold from 124.5m

including 1.5m @ 7.5% zinc, 2.50% lead, 113g/t silver and 1.59g/t gold

Of note is that hole PTDD036 terminated in mineralisation, hence potential exists to further extend this zone.

The results from the third hole in the drill program (PTDD037), the first to target a western extension of the Cathedral vein, have confirmed that mineralisation continues at least 80m to the west of the current resource, and that high grades are again in evidence. The best intercept is reported below:

·; PTDD037 - 5m @ 8.25% zinc, 0.19% lead, 25.1g/t silver and 0.52g/t gold from 177m

including 2m @ 16.5% zinc, 0.18% lead, 38.3g/t silver and 0.91g/t gold

Drilling continues on site, with the focus remaining on extending the Cathedral vein as planned. The program remains on schedule for all assay results to be returned by June 2010 with an expected update to the Company's Mineral Resource Estimate expected by mid-2010. Appendix 1 provides further information in relation to the drill holes noted above.

Commenting on the results, Managing Director Michael Bohm stated:

"We are pleased to see mineralisation being confirmed in the new vein and to see continuing high grades being achieved. Extending the Cathedral vein was always the main goal for this program so intersecting high grade mineralisation in the first hole is a great result. We continue to note the consistent presence of gold mineralisation in all the Paguanta veins which bodes well for future Project economics. Whilst early days, the opportunity to expand the current mineral resource estimate appears likely."
