“Firstly I’d like to thank you for the quick turnaround of our order.Once we received the two trial cold weather tray we sent one off to a local meat processing plant where it was placed in front of a cold air chiller fan for about seven days. This meant it was constantly blasted with air at a temperature of about minus 20 Celsius or more. After seven days we then asked the meat workers to see if they could break it, assuming it would crack after being frozen, they tried, but failed. They twisted and bent it, but it did not break. The second tray was then taken out to Canada and buried in the snow to see how it got on with being frozen down like that; it’s still in one piece as well. Once I’ve got the core yard set up I’ll get some pictures to you.”

“Rest assured that I am very impressed with the product that you market, and its use in Oyu Togloi is now well underway.  The drillers and core-handlers are equally impressed with its performance in the field and finally, I am hugely appreciative of your efforts for us. Thanks again for this, and I commend you and your company for an outstanding product that we will be both happy and proud to use.”

“We use the Discoverer core trays here and I personally find them fantastic. After palletising and re-traying pallets of core from metal/galvanised trays which were bent, had busted pop rivets, had decayed from reactions with massive sulphides and simply stacked unstably on pallets (even though racks are great, it’s hard to move large holes about if you need too) I’d be very hesitant to use anything but plastic core trays.”

“Aluminium trays introduced in the late 1960’s were found to rot when sulphide bearing ores broke down in them. Cardboard trays were light but had to be stored inside at great expense to ensure their long life. Wood trays with galvanised metal bases proved to be the most durable; however core had to be re-boxed at regular intervals if sulphide ores or termites were present.

An early attempt at using inferior plastic trays in North Queensland, Paul was very familiar with, these trays disintegrated in the sun; a bio-degradable core tray was not what the industry wanted.  Paul was heavily involved in the drill core handling systems for WMC at Ernest Henry in North Queensland and the Philippines and I believe it was after handling many thousands of metres of core in trays that Paul decided to invest his own money into inventing the tray for the 21st century.  He sent me two of his original plastic core trays with the instruction to leave them outside and see if they fell apart or if someone could break them. They are still in the backyard having served as plant boxes, dog barriers and the base of skate board ramps. They have not degraded.  

Companies I have worked with have used the trays around the world. We shipped some into Kazakhstan to handle core in freezing to very hot conditions in remote locations where we did not want to build sheds to store the wooden handmade ones used in that part of the world. The trays are universally liked by the people who handle them, as they allow the core to sit below the lip of the trays and the trays to be stacked and bundled efficiently for transportation. Drain holes, rough marking areas for writing on them and hand slots to allow ease of lifting were all unique innovations at the time. Old core from programs going back 30 years have had to be re-boxed at Cloncurry as the older trays have rotted out and the metals corroded away due to the attack of the sulphides ores.

These trays were stored in sheds. Based on the back yard test we do not expect to have to re-box the core in the ‘explorer’ trays which are now stored outside. Paul put a lot of time, effort, experience and money into developing the Explorer core tray system using 30-40 years of knowledge of the inadequacies of the previous core tray systems. His technical design drafting skills no doubt contributed greatly to the success of the core tray. At the time of its development the Explorer tray was unique in its innovations and usefulness.”
