Progradex 
In collaboration with Driconeq and drilling project management company Geolorn Ltd, Progradex has supplied an EL850CS RC sampling package to leading independent drilling contractor, Apex Drilling Services for drill sampling programmes within the UK.
The package was initially successfully tested in the coalfields of South Wales and is now providing quality sampling support in limestone quarrying marking a new era for the drilling industry and RC sampling concept in the UK.

Britain’s decision to leave the European Union has provided a boost to British exporters as the short term value of the Pound (£) falls by around 10% post Brexit.
Progradex Managing Director, Toby Day, commented, “In all the turmoil of Brexit, there has never been a better time to buy a Progradex Sampling System as our export position has suddenly improved greatly as a consequence of the resulting exchange rate fluctuation. This means you can get a Progradex product 10% cheaper this week than you could last week. We are also going to match that with a further 10% price reduction on top to make it a 20% reduction. When you combine this with the market reaction to gold (increasing in value by about the same percentage since Brexit), mining, particularly gold mining, has become very attractive once again after being in a 4 year slump.
“This is a big opportunity for all and we are going to try and take advantage of the volatility and use it to breathe some life back into the industry.”
New independent scientific papers are increasingly being published on the positive effect of using Progradex sampling systems to vastly increase bottom line profit, safety and overall mining efficiency. With this, and these additional incentives, it is expected to make Progradex the value adding proposition for mining.
New Scientific Papers relating to results from Progradex PGX Series Sampling Systems will be presented at two AusIMM Conferences later in the year.
“Simple Facts About Sampling Gold Ores” will be presented by Dr Geoff Lyman – Principal, Materials Sampling & Consulting Pty Ltd – at the 13th AusIMM Mill Operators’ Conference 2016 on 10-12th October 2016 at the Pan Pacific Hotel in Perth, Western Australia.
“A Fine Looking Sample – The Importance of Fines in Grade Control Sampling” will be presented by Ben Reid – Senior Mine Geologist, Cowal Gold Mine (NSW), Evolution Mining Ltd – at the Ninth AusIMM Open Pit Operators’ Conference 2016 on 15-16th November 2016 at the Western Australian School of Mines Conference Centre in Kalgoorlie, Western Australia.

Sampling Error is complicated and is made up of many contributing and influencing factors (errors) which occur at different stages of the various sampling processes, all of which combine to form what is known as the “Overall Estimation Error (OEE)”.
By far the largest percentage of Overall Estimation Error (OEE) occurs at the first stage however, the drilling stage, where the initial samples are taken. Errors here are grouped into five recognised categories:-
These five sampling errors are all derived at the drilling stage (drill sampling) and bias here accounts for approximately 1000% of the Overall Estimation Error (OEE) compared to around 50% for the second stage, known as Preparation Error (IPE), and approximately 0.1% at the third stage, known as Analytical Error (AE). The second and third stages occur after drilling once samples are presented to the lab for processing and, while very important, have a relatively small impact on the Overall Estimation Error (OEE) compared to those seen at the drilling stage. This is why it is critical to get your drill sampling right from the outset because the impact of every error thereafter pales into relative insignificance by comparison.
Other than the Fundamental Error (FSE), which is unavoidable though can be managed, a Progradex Sampling System will entirely remove all other sampling errors at the initial drilling stage for the following reasons:-

In addition to the recent announcement that Japanese machine manufacturing giant, Furukawa, has chosen to partner with Progradex and Driconeq to produce a new RC Grade Control rig offering for the global market, emerging German rig manufacturer, BBurg, has also released its new HD1650D rig for RC Grade Control at Bauma 2016 in Germany this week featuring the Progradex EL850 sampling system as standard.

Progradex has this week announced the imminent release of another new sampling system product line. Termed the MR1000, it is said to fill the mid-tier gap in the market between the highly successful and prized Progradex PGX1350 Series Samplers and their recently released EL850 Entry Level Sampler.
Details are still under wraps but it is said to be a rotary splitter that is almost unblockable, provides around 400 fully cross-sectional slices of the interval per metre drilled into duplicate sample bags and is only around 2.3m tall.
With the beautiful backdrop of Table Mountain and Lions Head Mountain (cover picture), Progradex attended the 2016 Mining Indaba Conference in Cape Town, South Africa in February (6th-9th). It is currently the world’s largest mining investment event and Africa’s largest mining event.
Managing Director, Toby Day, represented Progradex and commented, “While the conference was understandably a little quieter than usual this year due to the current downturn in the global mining industry, all of the main players were there and it was a great opportunity to reestablish relationships with old friends and acquaintances from the industry, some of whom had traveled from all over the world. Some good leads came out of the networking that goes on at such events and potential opportunities in partnership with others were formed.”
