The type of production drill utilized in a mining operation will depend on the drilling and blasting requirements, rock mass characteristics, and the stope design. There are two primary types of production drills: Longhole drills and down-the-hole (DTH), which are also referred to as in-the-hole (ITH) drills.

Test drilling for gold is an important step in prospecting and eventually commercially mining for gold. Test drilling is done to get a continuous sample of the bedrock of a given gold project. The sample is then tested to determine if there is gold in the project area and to estimate the amount of gold that can be mined in the area.

The development of guided microdrill systems for the shallow depths of many mineral exploration projects will be challenging. Drilling generally represents the largest single cost associated with mineral exploration and the delineation of an ore deposit once it has been discovered. ... shorten the time required to determine if a drill hole had ...
Drilling has to stop when groundwater is encountered as the hole quickly becomes clogged with mud. Surveying A Drill Hole. The deeper the drilling the greater is the need for down-hole surveys. These are important drill holes can be very off course. A survey will confirm the actual angle and direction of the holes at a specific depth.
Services Overview. Since its inception, REI Drilling has been on the leading edge of directional drilling applications for the mining industry. Our first projects focused on coalbed methane commercialization and degasification, but since those humble beginnings, we have continuously added new approaches and capabilities including geologic exploration, abandoned mine verification, and dewatering.

ONTARIO - Falcon Gold received an exploration and drill permit to carry out activities on the gold, silver, and copper prospects on its project in Ontario. In a press release, Falcon said that the permit includes over 20 drill pad locations, overburden trenching, and geophysical surveys to test historic prospects and expand the company's geologic understanding.
Considering every viable project will need hundreds of drill holes, the cost of exploration drilling can rise to millions of dollars. Furthermore, there is no guarantee of returns. However, it is not the drilling that provides the value of a mining project, the value is found in the samples obtained from drilling and their analysis to determine ...
The mining sector continues to look for ways to improve efficiencies and lower costs and drilling companies are following suit. At the end of the day, the best drilling contractors know that it's all about providing maximum value to the customer. Drilling the meters is only one part of the equation and other metrics provide guidance to total ...
Here, you can browse by company name, mineral project and by country to see which mining companies use Corebox to visualize their drill results.
