Hi Safe,
Good to hear that you plan to take a more pragmatic approach to understanding developments at Sunrise. You also said this;
“I did not see any suggestion in the RNS that the appointed contractor had messed up”
Ok from the 27th October RNS PC said;
A. “The Company has recently contracted Kimball Equipment Company of Reno, Nevada to supply and operate a mobile crushing and screening plant to process a 100-ton bulk sample of raw perlite from the Company's CS Project”
B. “The plant will comprise a crusher, high frequency screens and associated conveyors and will be a basic version of the plant that is proposed for the initial production facility”
C. “The perlite bulk sample will be processed into two separate size-grades of horticultural raw perlite. Interest in a new source of raw perlite has been very strong and material will initially be sent to five potential customers who will expand the raw perlite in their commercial facilities. Plans to supply additional customers are in progress”
It is clear what Sunrise expected in terms of the Contractor processing the raw material and providing 2 different grade sizes.
In Tuesday’s RNS we had this info;
“The Company's testing and analysis shows that during the crushing and screening process carried out by the Company's contractor the screens operated inefficiently resulting in over-crushing of the perlite and the inclusion of too much fine perlite in the products and that this is likely to have adversely affected the quality of the expanded product. The supply of a coarser particle size can be resolved with small adjustments to the crushing and screening process but in this case only 100 tons of material was available for processing and there was insufficient opportunity to optimise the crusher and screen settings”
It seems clear to me that whomever operated the crush/screen plant (presumably Kimball) did not have the settings quite right. We probably did have in the samples some Perlite at the correct size. But due to screens not being set/working correctly it seems like some over crushing happened and some finer material got through the processing. It is a bit like the cat litter we use at home, there are typically large granules but also some much finer ones.
My issue is whether SRES had anyone overseeing the processing to check the produced material looked correct. It feels to me that the Contractor knew things were not quite right but sent the stuff out anyway,
Safe, another point. I believe in the past that you have complained at Sunrise sending out Pozz and Perlite samples free of charge. Perhaps you will now look at things in a slightly different light. This customer spent time and effort/cost (heating our samples would not be cheap) testing what we supplied and it presumably cannot be used or is sub standard. If we had charged for this material I think the customer would be mightily cheesed off.
