The diameter of mineral exploration drill holes (called slimholes) is generally much smaller than the diameter of either petroleum or geothermal wells. Therefore, many of the down-hole tools used for drilling in the petroleum and geothermal fields are too large to be used in the mineral exploration slimholes. The need for miniaturization of ...

In mineral exploration, targets need to be confirmed by means of drilling. Such drilling is based on anomalies often detected in geochemical and/or geophysical exploration. Because drilling is costly and because mineral exploration has low success rate, the need to know quickly, with minimal drilling, whether a target is mineable or not, …

There are two main methods of exploration drilling - core drilling and reverse circulation drilling (usually referred to as RC). Core drilling, yields a solid, cylinder shaped sample of the ground at an exact depth. Reverse circulation (RC) drilling, yields a crushed sample, comprising cuttings from a fairly well determined depth in the hole.
