EDMONTON, Alberta; August 8, 2006 - Mindoro Resources Ltd. (TSXV: MIO; Frankfurt: OLM) today reported additional encouraging gold grades from a further six drill holes, including 28 meters of 1.07 grams per tonne (g/t) gold, from the Kay Tanda epithermal gold-silver prospect, located in the Archangel Project, the Philippines.
Results from an ongoing reverse circulation drilling program are giving thick intersections of low-grade, near-surface, oxide gold-silver mineralization. Previous results are reported in releases dated May 3, May 23, June 16, July 4, July 25, and Aug. 1, 2006. The drill holes continue to extend the near-surface mineralization beyond the previously known limits and infill drilling is confirming mineralization continuity. Location of all drill holes to date are shown the map accompanying this release and on Mindoro's website at www.mindoro.com. A summary of results from the recent drilling at Kay Tanda (KT) follows:

KT-22: 69 meters of 0.62 g/t gold and 1.75 g/t silver, including 28 meters of 1.07 g/t gold and 2.56 g/t silver; an infill hole confirming mineralization continuity 50 meters from adjacent drill holes on section, and 100 meters between adjacent sections

KT-23: 14 meters of 0.44 g/t gold; an infill hole, confirming mineralization continuity 50 meters from adjacent drill holes

KT-24: 14 meters of 0.66 g/t gold and 8.46 g/t silver; an infill hole confirming mineralization continuity 50 meters from adjacent holes

KT-25: 38 meters of 0.53 g/t gold; an infill hole confirming mineralization continuity 50 meters from adjacent holes (silver results not yet received)

KT-26: 14 meters of 0.36 g/t gold, followed by 36 meters of 0.34 g/t gold; extends mineralization a further 50 meters to the north and west of known mineralization (silver results not yet received).

KT-27: 30 meters of 0.75 g/t gold, including 6 meters of 1.25 g/t gold; an infill hole confirming mineralization continuity 50 meters from adjacent holes (silver results not yet received).
GRADES IN LINE WITH SUCCESSFUL GOLD MINES ELSEWHERE
Mindoro's management notes that grades continue to be in line with successful and low-cost, open-pit, heap-leach mines elsewhere in the world. For example, Glamis Gold Ltd., a profitable intermediate-sized gold producer, reports on its website Proven and Probable Reserves for its Marigold Mine of 59,396,000 tonnes at a grade of 0.72 g/t gold (Glamis 66% share); for its San Martin Mine, 10,775,000 tonnes at a grade of 0.76 g/t gold; for the giant Penasquito deposit, currently being developed, 564,000,000 tonnes at a grade of 0.55 g/t gold and 31.7 g/t silver. At Penasquito, one of the pits grades 0.38 g/t gold and 25.4 g/t silver, and another pit 0.22 g/t gold and 20.3 g/t silver. For the Imperial Project, Glamis reports Measured Resources of 67,877,000 tonnes at a grade of 0.59 g/t gold.

CORING RIG MOBILIZED TO COLLECT METALLURGICAL SAMPLES
A diamond drill rig has been mobilized to Kay Tanda to collect large diameter core samples of both oxide and non-oxide material for a new phase of metallurgical testing. The metallurgical test-work will be supervised by P. J. Lewis and Associates, metallurgical consultants of Australia, and the work will be carried out at Metcon Laboratories of Australia. Drilling will commence this week.
