5 Myths about Diamond Drilling

Posted by Rod McCoremick on Mar 12, 2018 11:30:00 AM

Whether you work in diamond drilling or another industry, we all face some misconceptions about our jobs. For me, it appears that when people ask what I do and I tell them I’m a diamond driller, there are always false assumptions and some confusion. Maybe it’s because it is not a well-known industry in general but I find myself repeating the same corrections. In this week’s blog, I thought it would be interesting to look at the most common myths about diamond drilling.

Posted by Rod McCoremick on Feb 19, 2018 12:35:57 PM

 A lot of the time I talk about the different challenges and problems diamond drillers face when the drill site is off in some remote location. It gives the impression that all diamond drilling is done in rural settings, off the beaten track. Now we know that geotechnical drilling happens in urban centers but there are times when a mineral exploration drill site is located in the city.

When is Diamond Drilling Like Football?

Posted by Rod McCoremick on Feb 5, 2018 4:00:00 PM


Drilling a deep hole is a challenge for even the most experienced drillers. So many things can go wrong, from hole deviation to equipment failure. Drilling deep holes is not for amateurs because making a mistake at 1,500 meters becomes an expensive mistake and something every driller wants to avoid. I often say that improving drilling performance and making drillers’ lives easier are our goals, and we are constantly trying to innovate and develop products to help achieve those goals.

Tips for High Altitude Diamond Drilling

Posted by Rod McCoremick on Jan 8, 2018 10:30:00 AM

Sometimes in diamond drilling the drilling operation takes you to far away lands that are high up…really high up. Drilling that is performed at altitudes that are higher than 15,000 feet is considered high altitude drilling. The problem with high altitude drilling is the adverse conditions that drillers will encounter. These adverse conditions will affect the health of drillers and how drilling equipment performs. When you start getting higher than 10,000 feet, getting enough oxygen becomes a challenge not just for drillers but for your engine and hydraulics as well.
