2017 Report: Mineral Exploration Australia

Mineral exploration is the process of gathering information to assess the mineral potential of a given area by determining geologic anomalies that may lead to mineral discovery. Drilling programs are then undertaken to provide estimates of the extent and quality of the deposit. The immediate product of exploration is the identification and geological knowledge of […]

Sitech WA helps Castle Drilling Complete Project

Last year, Castle Drilling Company was contracted to complete an extensive drilling project, creating 200 2.5-metre-deep holes per day. Due to the size and nature of this project, Castle Drilling enlisted the help of Sitech WA.

An Introduction to Reverse Circulation Drilling

When choosing a drilling method, especially for exploration and grade control, one must consider many factors such as cost, time, environmental impact, depth of drilling and sample quality. Reverse Circulation drilling offers many advantages over other drilling methods, such as Rotary Air Blast drilling or diamond drilling. This article will explain what Reverse Circulation drilling […]

What is Reverse Circulation (RC) Drilling? [Inc. Video]

Reverse circulation (or RC as it’s more commonly known) drilling is an essential tool in the mining industry. In addition to other oil rigs and drill rigs, reverse circulation drills assist in the productivity and accuracy in mining jobs. RC drilling is a drilling method involving a large rotary drill and air compressor that yields […]

RC Drillers achieve 0.3% sample errors from a 9000 sample population

During a recent Reverse Circulation exploration drilling campaign, Castle Drilling Company delivered the client 100% sample return (2x 20kg samples with nosample loss at all), and 28 errors over a sample population of 9000. These errors largely consisted of spilt bags and numbering issues which were easily rectified. The challenge during the 6 week program […]

What is grade control and how can it save you time?

Traditionally, a geologist oversees grade control in the mining industry. However, over the past two decades, we have seen an emergence of technology that assists with this procedure. Today will take a closer look at grade control and how it can improve the mining industry. What is Grade Control? Grade control is an essential part […]
