Mindoro Resources Limited has announced the first drill hole result from the Archangel drilling program designed to test interpreted high grade feeder structures underlying the near surface Archangel resources in Batangas in Philippines.

Three holes have been completed in the program. The initial drill hole, PL-188, cut a near surface stock work zone and produced an intersection of 26.7 meters @ 2.19 grams per tonne gold from 19 meters down hole depth, including 6.7 meters @ 7.7 grams per tonne gold from 22.3 meters.

The initial drill hole PL-188 provided important information as to the orientation of high grade hydrothermal breccia veins from 1.25 meters @ 10.73 grams per tonne Au, 130.6 grams per tonne Ag from 24.5 meters. On the basis of this information PL 190 was drilled in a different orientation targeting northwest southeast trending structures. PL-190 subsequently intersected a 48 meter down hole thickness of hydrothermal breccia mineralization from 1.9 meters. Assay results from this hole are not yet available.

Drill core samples are prepared and analyzed by Intertek Testing Services Philippines Inc. laboratories. Gold assays were by 50 gm fire assay fusion; where gold assays greater than 3 ppm were by gravimetric finish and by AAS where the gold values were less than that threshold. Silver and copper were determined by ICP after a four acid digest. Normal Quality Control and Quality Assurance procedures are being carried out, using a system of duplicate, standard and blank samples.
