FAQs for Discoverer® Core Trays / Boxes

What are the Discoverer® core trays made of?

Yandina Plastics’ Discoverer® core trays are manufactured from the highest UV stabilised polypropylene available.

Why is it made from polypropylene?

  • The material has a high level of resistance to organic chemicals found in drill core recovery
  • It is highly resistant to impact
  • It is non-magnetic
  • It is exceptionally durable, making it suitable for the harsh mining / exploration environment

Why do you only manufacture four sizes?

The Discoverer core tray offers the industry a standardised mode of core storage. This minimises stock holdings by just carrying one range of standard sized products, instead of the multitude of sizes and types of metal trays.

Why is it manufactured as a one piece mould?

As the Discoverer core trays are a one piece molding they have no pop rivets and welds, which means increased product strength, less damaged and unusable trays, dramatically reducing wastage.

Why do the trays have rounded edges and handles with an optional ID tag?

  • Rounded edges mean no more dangerous sharp edges, leading to improved safety when handling
  • Built-in handles on both ends of the trays provide safe and easy use when handling
  • The built-in ID tag area and optional tags provide for a permanent record of contents

Why have the designers used a START marker?

A bold START mark at the end of the tray was designed to make it absolutely clear to the driller, at which end they should commence to load the core from the core barrel inner tube, thereby eliminating possible errors in logging the core.

Why are the trays made in different colours?

The trays are colour coded, allowing for quick and easy identification of the different sizes both in storage and out in the field.

Do the Discoverer core trays heat up when left out in the sun?

The plastic remains relatively cool to touch when left outside, unlike metal trays. Therefore no more painful burns when handling core trays.

Are the Discoverer core trays recyclable?

Yes, the Discoverer core trays are fully recyclable.

Why are there ribs in the Discoverer core trays?

The unique raised rib design has been incorporated as they improve drainage, whilst making it easier to slide the core into the tray. This assists in the field, helping to retain the quality of your core.

How long have the Discoverer core trays been in use?
