ROCKLABS December 2001...

CHRISTMAS AND NEW YEAR GREETINGS TO YOU FROM ROCKLABS!

NEW ROCKLABS CATALOGUE

Our new catalogue illustrating the full range of ROCKLABS equipment is now available.
The complete catalogue is on our website at www.rocklabs.com. Have you checked our website recently?

The biggest growth sector at ROCKLABS has been the manufacture of Mechanised Systems. However, we have continued working with Research Institutes and Universities to produce unique items of equipment such as the Bench Top Ring Mill.

Our Standard Ring Mill and associated Heads of agate, carbon steel, chrome steel, tungsten carbide, zirconia etc. continue to be sought after by laboratories world-wide.

MECHANISED SYSTEMS

Can you continue using labour intensive equipment in your laboratory when there is a better alternative readily available?

Can you ignore possible health hazards in the laboratory from heavy lifting, dust inhalation , noise, etc?

Can you continue missing out on the many benefits of Mechanisation such as cost saving, more representative samples etc. etc?

If you can, don't read the rest of this article, go to Reference Materials.

We have received orders for three Mechanised Systems for gold mines in North America.

Mechanised System No. 1 for Gold Mine in Nevada.

The Rodeo System: Designed and built for Barrick Gold's Rodeo Mine. This System can process underground samples up to 50 kg in weight with lumps up to 150 mm (6 inch). Other samples include drill core and any other mine sample from 1 to 50 kg.

Each sample is lifted up to a primary crusher and the output is conveyed up to a Boyd Crusher for a second, fine crush. The sample is then rotary split and a portion is pulverised in a CRM.

Mechanised System No. 2 for another Gold Mine in Nevada.

The Cortez System: Designed for Placer Dome's Cortez Mine. This System is for crushing and splitting large samples, e.g. large drill core.

Each sample of 1 to 20 kg is weighed , to control the output weight at a constant figure, regardless of the input weight. There are two stages of crushing and then rotary splitting. Samples will be pulverised in existing mills.

Mechanised System No. 3 for Gold Mine in Canada.

The Musselwhite Systems: Designed for another Placer Dome property in Canada.
These Systems are for processing a variety of sample types. The process includes weighing, crushing, splitting, pulverising.

CERTIFICATED REFERENCE MATERIALS FOR GOLD ASSAYING

7 new values will be available from January 2002. Please check this website regularly for the new values.

Reference Materials are now being used in 30 different countries.

Our aim has been to produce a high quality product that is affordable enough to be used on an every batch basis. The high quality of ROCKLABS Reference Material is achieved through the use of appropriate raw materials, a stringent homogeneity testing regime and the assignment of values through the use of 20 or more well recognised laboratories world-wide.

Remember the price of ROCKLABS Reference Materials is related to the volume you purchase. If you would like to start using them on an every batch basis, work out how much you are likely to use over a year and then ask us or your ROCKLABS Agent for the "bulk supply" price.

For those of you who receive our newsletter by post please accept our small gift of a desk calendar.

Best wishes for 2002.
