Progradex EL850CS Sampling System Video

The EL850CS is Progradex’s “entry level” sampling system …but don’t be fooled by the name. Packed with superior features as standard, the system requires no electrics yet is still a fully automatic sequenced sampling system that produces outstanding duplicate repeatability in all RC drilling applications.

The Heroes of the 33 Trapped Miners

A bit of history for you. The guys I’m with here work for a Chilean drilling company called Terraservice. This is the company that found the 33 trapped miners in the Chilean mining disaster a few years ago. The guy on the far left, Eduardo Hurtado, was the drilling supervisor on the actual hole that found them. He has since been involved as an advisor in the Hollywood film that was made [The 33] about the story and Terraservice’s drill rigs and equipment were used in the making of the film. The Chilean flag below is the actual flag that was flown on top of the rig during the rescue operation. It has been signed by all of the 33 rescued and now hangs in Terraservice’s reception in Copiapo.


I am privileged and honoured to say that Eduardo and his team, including the driller that drilled the miracle hole, will be helping me next week at Barrick’s Alturas Project in an exploration drilling programme to find gold. I am confident that, with Terraservice’s track record of finding the impossible, locating gold is going to be relatively easy.

Successful Atacama, Chile Test with Barrick

Phase 1 Trials of the Progradex PGX1350T Sampling System for Barrick Chile have been deemed successful in the Atacama Desert of Northern Chile. The system will now mobilise to Barrick’s Alturas Project, 5200m above sea level, with drilling contractor Terraservice for gold exploration.

The premium Progradex system has been selected on the basis of its unique ability to collect and sample the coarse and fines particulate (100% recovery for sampling) along with its other unique ability to provide around 400 complete cross-sectional slices of the interval in the sample bag per metre drilled, securing a complete cross-section of the interval in the sample bag every 2.5mm drilled including the fines.

Since the release of the Progradex PGX Series product line in 2010, 7% more gold is found as a direct result of sampling the fines that was previously lost from an RC chip sample. Only a Progradex sampling system can provide total sampling representivity,

Results are verified by a growing number of independent scientific papers worldwide.

Simple fact. No other sampling system on the global market has the ability to collect the fines for sampling or the representivity of prehomogenised, mechanically layered (blended) sample duplicates than a Progradex Sampling System.

Indisputable Evidence – The Necessity of Fines in a Sample

Click on the link to read an amazing and enlightening paper written by Ben Reid of Evolution Mining on the importance of fines collection in an RC Grade Control sample to achieve mine to mill reconciliation. Compiled with years of RC Grade Control data and verified by mine to mill reconciliation, the same must surely apply to RC exploration.

To The Apex^

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.

Brexit – A Boost for British Exports

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.
