Epithermal gold-silver mineralization at Kay Tanda is associated with extensive and intense quartz stockworks, veins and hydrothermal breccias, with accompanying base metal sulphides. Kay Tanda is reflected by an induced polarization chargeability anomaly that is about 1.5 kilometers by 1.4 kilometers in extent, which is part of a much larger chargeability anomaly which extends over six kilometers along strike to the northeast. To date, drilling has been conducted only on the Kay Tanda part of the trend.

Mindoro has completed 147 reverse circulation (RC) and twenty six core drill holes at Kay Tanda for a total of 23,042 meters of drilling. Almost all holes have encountered near-surface, generally flat-lying to gently-dipping blanket-like low-grade stockwork mineralization. This is strongly to partially oxidized to depths of 40 to 160 meters and non-oxide below this. Drilling, especially at deeper levels, has encountered at least five steeply-dipping, much higher-grade zones with bonanza grades to 246 g/t gold and over 1,000 g/t silver, which are interpreted as structurally controlled upflow, or "feeder" zones.

Structural studies are in progress to determine the nature and controls of the high-grade zones. The high-grade mineralization appears to occur preferentially at elevations below 250 meters (ASL) interpreted to be a paleo-boiling zone. Few holes have penetrated to this depth to date. Such upflow zones may be associated with bonanza mineralization that constitute some of the world's best epithermal gold-silver deposits.

Kay Tanda is being evaluated for its open-pit, heap leach potential. Initial metallurgical test work has produced excellent results. Kay Tanda is interpreted as intermediate to low sulphidation epithermal quartz-carbonate-gold-silver-base-metal mineralization telescoped into the top of an underlying porphyry copper-gold system.
