If you’re familiar with core processing and analysis, you know core trays serve a multitude of purposes; they are filled with core at the drill site, are used to safely transport the core from the site to the core shed or lab, assist in recording and sampling procedures, and used as a container to preserve the core. 

At Dynamics G-Ex our core business is in fact, the development and manufacture of core trays. We identify problems and solve them for geologists and field workers so they can do their job safely and efficiently.

So we developed superior core tray products such as the Discoverer Core Sample Trays. Innovation was our answer to the old core trays and its associated problems.

In this post, I thought we should take a look at how core trays have evolved over the years as a reminder of just how far we’ve come as an industry.

Metal Trays

Metal and galvanised trays were introduced into the industry decades ago. Although extremely sturdy, it has its own set of problems. The metal would bend and corrode as sulphide ores reacted with the metal. Metal trays were also heavy to lift, and after a day in the burning sun, became hot to handle, causing calluses and burns. Metal also stacked unstably on the pallets causing delays in transportation or loss of core from the tray if the stack collapsed due to this instability.

Cardboard Trays

It seems odd considering the large scale of mining and exploration operations nowadays, but cardboard trays were also developed to provide a solution to the increasing amount of core tray problems. The idea however was flawed from the beginning. On the one hand, cardboard trays are light and can be used by one person alone. But this is where its practical use ends. These trays have to be stored inside which only adds to lost productivity and employee frustrations, not to mention its  short life span.

Wooden Trays

Wooden trays are a popular solution, particular in colder parts of the world. Timber as a resource is readily available across the globe and as a material, it is strong but can be slightly heavier in weight. The downside to timber trays is that it is susceptible to termites and insects. Thus in many parts of the world, particularly tropical regions, this is not a practical solution. Wherever these are used in the world, these wooden boxes will rot out however, and you will encounter loss of core or sample bias in some form. 

Plastic Trays

Of course, given technological advancements, it wasn’t too long before plastic trays were developed. But the initial ones sold on the market were flimsy and would all too often disintegrate in the sun, needing constant replacement.

Our solution

Over the years, we researched, designed, developed, tested and continually improved our plastic core tray products. Now they are universally liked by the people who handle them: geologists, drillers, core-handlers and site workers who all report high performance in the field.

Our trays feature:

  • heavy duty UV stabilised polypropylene that can stand the test of time 
  • built in handles to provide safe and easy handling
  • different sizes to suit different core from BQ to PQ
  • available in a variety of colours for different uses e.g. black for HyLogging 
  • drainage holes to help your core dry out and remain stored in premium condition
  • improved design allows trays to be stacked and bundled efficiently for storage and transportation
  • variety of accessories available for ease of use and core protection e.g. ID tags, plastic and wooden core markers and lids

We at Dynamics G-Ex understand that there really is no one core tray style fits all given project requirements, cost, availability, suitability and personal preferences. Therefore, we offer a wide selection of core boxes, including plastic core trays, to suit every conceivable condition in the field.
